For example, the timing at which the edge device 4000 generates the second information may be before the second information is acquired by the server device 3000, and is not limited to the timing illustrated in FIG.

  Hereinafter, the information collection system 2000 of this embodiment will be described in more detail.

<Details of First Information Generation Unit 4020>
The first information generated by the first information generation unit 4020 is various. For example, the first information generation unit 4020 determines whether an abnormality has occurred in the edge device 4000 having the first information generation unit 4020 or the monitoring target device of the edge device 4000. And the 1st information generation part 4020 produces | generates the 1st information which shows the result of this abnormality determination.

  The result of the abnormality determination regarding the edge device 4000 or the monitoring target device of the edge device 4000 represents, for example, the result of the abnormality determination regarding any one or more of each element (hardware or software) included in the edge device 4000. Further, for example, the result of the abnormality determination regarding the edge device 4000 or the monitoring target device of the edge device 4000 represents one abnormality determination result regarding the entire edge device 4000 or one abnormality determination result regarding the entire monitoring target device.

  Further, the first information generation unit 4020 acquires one or more parameters representing the state of the edge device 4000 having the first information generation unit 4020 or the monitoring target device of the edge device 4000, and indicates the acquired parameters. 1 information is generated. In this case, for example, the first information is the usage rate of each computer resource included in the edge device 4000 or the monitoring target device.

  Further, for example, the first information generation unit 4020 generates, as the first information, information indicating the position of the edge device 4000 having the first information generation unit 4020 or the monitoring target device of the edge device 4000 (hereinafter, position information). To do. Since the technique for generating position information is a known technique, the description of the method for generating position information is omitted.

<Details of Second Information Generation Unit 4040>
The second information generated by the second information generation unit 4040 is various. For example, the second information indicates detailed information regarding an abnormality occurring in the edge device 4000 or the monitoring target device of the edge device 4000. For example, the detailed information includes the details of the abnormality, the current detailed status of the edge device 4000 or the monitoring target device, or a log regarding the status of the edge device 4000 or the monitoring target device.

  For example, assume that the monitoring target device is a gas cylinder. In this case, for example, the second information may indicate the remaining amount of the gas cylinder. Thereby, for example, when the first information indicating that an abnormality has occurred in the gas cylinder is acquired, whether or not a gas leak has occurred and how much gas has leaked based on the second information. And so on.

  For example, assume that the monitored device is a vending machine. In this case, for example, the second information may indicate the remaining number of each product or the number of each coin or banknote in the vending machine. Thereby, for example, when the first information indicating that the casing of the vending machine has been opened illegally is acquired, whether or not the product or money is lost based on the second information, You can know the number and amount of money.

  In addition, for example, it is assumed that the first information indicates position information indicating the position of the edge device 4000. In this case, for example, the second information also indicates position information indicating the position of the edge device 4000. For example, in this case, the collection rule indicates the collection frequency of the second information, and this frequency is set higher than the frequency of the first information. The collection rule is applied when the position of the edge device 4000 indicated by the first information is within a predetermined distance from the server device 3000. By doing so, “when the edge device 4000 is away from the server device 3000, the server device 3000 grasps the position of the edge device 4000 less frequently, and when the edge device 4000 approaches the server device 3000, the server device 3000 Can grasp the position of the edge device 4000 at a high frequency ". Thereby, it is possible to realize a monitoring system that monitors the position of the edge device 4000 at an appropriate frequency while suppressing the load on the information collection system 2000.

  Further, for example, it is assumed that the first information is position information of the edge device 4000, and the edge device 4000 is a device provided in the vehicle. For example, in this case, the server device 3000 acquires information for providing a service to the vehicle based on the position of the vehicle as the second information. For example, it is assumed that server device 3000 provides a service that prompts a car to refuel at a gas station. In this case, the second information is the remaining amount of gasoline in the car. And the collection rule which acquires this 2nd information is applied when the position of the car which the 1st information shows is near a gas station. When the position of the vehicle indicated by the first information is near the gas station, the server device 3000 acquires the second information indicating the remaining amount of gasoline in the vehicle. And the server apparatus 3000 transmits the position information of a gas station with respect to the edge apparatus 4000, when gasoline remaining amount is below predetermined amount. For example, in this case, the edge device 4000 is preferably a car navigation system. The edge device 4000 can prompt the driver to go to the gas station by displaying the position information of the gas station received from the server device 3000 on the screen.

<First information collection method>
There are various methods by which the first information acquisition unit 3020 acquires the first information. For example, the first information acquisition unit 3020 acquires the first information by receiving the first information transmitted by the edge device 4000. In this case, the edge device 4000 includes a first information transmission unit 4060 that transmits the first information of the edge device 4000 to the server device 3000. FIG. 5 is a block diagram illustrating an information collection system 2000 when the edge device 4000 includes the first information transmission unit 4060.

  There are various triggers for the first information transmission unit 4060 to transmit the first information. For example, the first information transmission unit 4060 transmits the first information when receiving an instruction from the first information acquisition unit 3020. In this case, the server device 3000 includes a functional configuration unit that requests the first information transmission unit 4060 to transmit the first information.

  Also, for example, the first information transmission unit 4060 transmits the first information regularly or irregularly. When the first information transmission unit 4060 transmits the first information irregularly, for example, the first information transmission unit 4060 is triggered by the change in the state of the edge device 4000 having the first information transmission unit 4060. 1 information is transmitted.

  The server device 3000 may acquire the first information by reading the first information from the first information storage unit 4030 in which the first information is stored. In this case, the edge device 4000 includes a first information storage unit 4030 that stores the first information generated by the first information generation unit 4020. FIG. 6 is a block diagram illustrating an information collection system 2000 when the edge device 4000 includes the first information storage unit 4030.

<Second information collection method>
There are various methods by which the second information acquisition unit 3040 acquires the second information. For example, the second information acquisition unit 3040 acquires the second information by receiving the second information transmitted by the edge device 4000. FIG. 7 is a block diagram illustrating the information collection system 2000 when the second information is transmitted by the edge device 4000.

  In this case, the edge device 4000 acquires a collection rule from the server device 3000 and transmits the second information according to the acquired collection rule. For this purpose, the server device 3000 includes a collection rule transmission unit 3100. The collection rule transmission unit 3100 transmits a collection rule applied to the edge device 4000 to the edge device 4000.

  The edge device 4000 includes a collection rule reception unit 4080 and a second information transmission unit 4100. The collection rule receiving unit 4080 receives from the server device 3000 a collection rule applied to the edge device 4000 having the collection rule receiving unit 4080. The second information transmission unit 4100 transmits the second information to the server device 3000 based on the collection rule.

  The second information generation unit 4040 may acquire the collection rule received by the collection rule reception unit 4080 and generate the second information according to the collection rule. In this case, the second information transmission unit 4100 transmits the second information generated by the second information generation unit 4040 to the server device 3000.

  However, the second information generation unit 4040 may generate the second information regardless of the collection rule. In this case, the second information transmission unit 4100 selects second information to be transmitted to the server device 3000 from the second information generated by the second information generation unit 4040 based on the collection rule. Then, the second information transmission unit 4100 transmits only the selected second information to the server device 3000.

  The server device 3000 may acquire the second information by reading the second information stored in the edge device 4000 based on the collection rule. In this case, the edge device 4000 includes a second information storage unit 4050 that stores the second information generated by the second information generation unit 4040. In this case, the server device 3000 may not transmit the collection rule to the edge device 4000. FIG. 8 is a block diagram illustrating an information collection system 2000 when the edge device 4000 includes the second information storage unit 4050.

<Details of collection rules>
As described above, the collection rule indicates any one or more of the content of the information included in the second information, the frequency of acquiring the second information, and the edge device 4000 to which the collection rule is applied. For example, it is assumed that the first information indicates that an abnormality has occurred in specific hardware included in the edge device 4000. In this case, for example, the content included in the second information is a detailed status regarding the specific hardware.

  For example, it is preferable that the frequency of acquiring the second information indicates a shorter time interval as an abnormality occurring in the edge device 4000 or the monitoring target device is more serious.

  For example, the edge device 4000 to which the collection rule is applied may be the edge device 4000 that is the generation source of the first information, or may be the edge device 4000 other than the generation source of the first information. Here, it is assumed that each edge device 4000 monitors the state of any other edge device 4000. In this way, when an abnormality occurs in an edge device 4000, detailed information regarding the abnormality of the edge device 4000 can be acquired from another edge device 4000 that monitors the edge device 4000. Therefore, even when the edge device 4000 in which an abnormality has occurred cannot generate the second information, information regarding the abnormality relating to the edge device 4000 can be collected. This can be realized by making the edge device 4000 to which the collection rule is applied different from the edge device 4000 from which the first information is generated.

  The collection rule may indicate further information. For example, the collection rule may indicate a compression method of the second information. For example, the first information transmission unit 4060 described above transmits the second information after compressing the second information according to the compression method indicated in the collection rule. Further, for example, it is assumed that the second information acquisition unit 3040 reads the second information from the second information storage unit 4050 described above. In this case, for example, the second information acquisition unit 3040 compresses the second information in the second information storage unit 4050 by a method according to the collection rule, and then reads the second information. By doing in this way, when the server apparatus 3000 acquires 2nd information, the load concerning the communication network 10 can be reduced.

  Further, for example, the collection rule may indicate a time point when the collection of the second information is started. Thereby, for example, the second information can be collected from each server device 3000 at different times. Even if the collection frequency of the second information is the same in the two server apparatuses 3000, the timing at which the two server apparatuses 3000 collect the second information does not overlap if the time point at which the collection of the second information starts is different. . Therefore, the load applied to the communication network 10 can be reduced.

<< Collection Rule Table 200 >>
FIG. 9 is a diagram illustrating information stored in the collection rule storage unit 5000 in a table format. The table shown in FIG. 9 is referred to as a collection rule table 200. Each record of the collection rule table 200 indicates a record ID 202, a signal set 206, contents 208, a frequency 210, an application target 212, a priority 214, and an application count 216. A record ID 202 indicates the ID of the record. The signal set 206 represents a combination of “edge device 4000, first information” associated with the collection rule. For example, the signal set 206 of the record in the first row in FIG. 9 represents a combination of “first information of edge E1, x = s0”. That is, when the first information acquisition unit 3020 acquires the first information x = s0 from the edge E1, the collection rule acquisition unit 3060 acquires the collection rule indicated by the record in the first row in FIG.

  The collection rule is represented by the content 208, the frequency 210, and the application target 212. The content 208 indicates the content of the second information. The frequency 210 indicates the frequency of collecting the second information. The application target 212 indicates the ID of the edge device 4000 to which the collection rule is applied. The priority 214 and the application count 216 will be described later.

  The collection rule acquisition unit 3060 searches the collection rule table 200 for a record corresponding to a combination of “the first information acquired by the first information acquisition unit 3020 and the edge device 4000 from which the first information is generated”. Specifically, the collection rule acquisition unit 3060 indicates that the value of the signal set 206 is “first information acquired from the first information acquisition unit 3020, the generation source of the first information” from the records of the collection rule table 200. The record that matches the combination of the edge device 4000 ”is specified. Then, the collection rule acquisition unit 3060 acquires the content 208, the frequency 210, and the application target 212 of the specified record as a collection rule.

  The signal set 206 may represent a combination of values indicated by a plurality of pieces of first information. For example, the signal set 206 of the record in the second row in FIG. 9 has a conditional expression “acquires first information x = s1 from edge E1 and obtains first information y = s1 from edge E2”. Represent. The signal set 206 is a conditional expression representing a logical sum such as “obtain first information x = s1 from the edge E1 or obtain first information y = s1 from the edge E2”. Also good. As described above, by setting the collection rule based on the combination of the first information received from the plurality of edges, it is possible to collect the second information in consideration of the states of the plurality of edges.

  The signal set 206 may represent a combination of values indicated by the first information acquired within a predetermined time. For example, the signal set 206 of the record in the third row in FIG. 9 obtains “first information x = s2 from edge E1 and y = s2 from edge E3, and two This represents the condition that the difference in the reception time of one information is within 10 seconds.

  Further, the signal set 206 may indicate that the same determination result or parameter value is indicated in the first information continuously for a predetermined number of times or more. For example, the record on the fourth line in FIG. 9 indicates that “first information x = s3 is acquired three times continuously from the edge E4”.

  When the signal set 206 indicates a combination of values indicated by a plurality of first information, the first information acquisition unit 3020 stores the acquired first information in a buffer or the like in association with the acquisition time point or the like. . The collection rule acquisition unit 3060 searches the collection rule table 200 with reference to the first information stored in this buffer.

  The application count 216 indicates how many times the collection rule indicated in the record is applied to the collection of the second information. For example, the application count 216 of the record in the first row in FIG. 9 indicates “10 times”. Therefore, the acquisition of the second information to which the collection rule indicated by this record is applied is performed 10 times. Each record of the collection rule table 200 may represent the length of time to be applied instead of the number of times of application 216.

  It is assumed that a plurality of records are specified when the collection rule acquisition unit 3060 searches the collection rule table 200. In this case, for example, the collection rule acquisition unit 3060 acquires the collection rule from the record indicating the highest priority among the plurality of identified records. Further, the collection rule acquisition unit 3060 may acquire a record having the smallest record ID 202 from the plurality of specified records. Further, the collection rule acquisition unit 3060 may acquire a record with the latest generation date and time from the plurality of identified records.

  Note that the collection rule table 200 may be configured such that each signal set 206 always shows a different value. In this case, when the collection rule acquisition unit 3060 searches the collection rule table 200 for a record that matches the first information, a plurality of records are not specified.

  Furthermore, when a plurality of records are specified, the collection rule acquisition unit 3060 may acquire a collection rule from each of the plurality of records and apply the collection rules in order of priority. For example, it is assumed that the search result by the collection rule acquisition unit 3060 is two records X and Y. Further, it is assumed that the number of application times 216 of the record X having a high priority indicates 5 times, and the number of application times 216 of the record Y having a low priority indicates 2 times. In this case, after the second information is acquired five times according to the collection rule indicated by the record X, the second information is acquired twice according to the collection rule indicated by the record Y. For example, if a higher priority record is indicated, the server device 3000 can perform an operation of acquiring the second information while gradually decreasing the acquisition frequency of the second information.

  There are various timings at which the second information acquisition unit 3040 acquires the second information. For example, the acquisition of the second information is performed only when the collection rule is acquired by the collection rule acquisition unit 3060. In addition, for example, when the collection rule acquisition unit 3060 does not acquire the collection rule, the second information may be acquired regularly or irregularly.

  When a collection rule (hereinafter, collection rule 1) is applied to an edge device 4000, another collection rule (hereinafter, collection rule 2) that the collection rule acquisition unit 3060 applies to the edge device 4000. ). There are various ways of handling the collection rule 2 in this case. For example, the application of the collection rule 1 is stopped and the collection rule 2 is newly applied. Further, the collection rule 2 need not be applied. Further, the collection rule 2 may be applied after the collection rule 1 is applied. Further, a priority is given to the collection rule (eg, priority 214 in the collection rule table 200), and the application of the collection rule 1 is stopped only when the priority of the collection rule 2 is higher than the priority of the collection rule 1. Thus, the collection rule 2 may be applied.

[Embodiment 2]
FIG. 10 is a block diagram illustrating an information collection system 2000 according to the second embodiment. In FIG. 10, arrows indicate the flow of information. Further, in FIG. 10, each block represents a functional unit configuration, not a hardware unit configuration.

  In the information collection system 2000 of the present embodiment, the second information is collected in consideration of the load on the information collection system 2000. Therefore, the server device 3000 includes an upper limit value storage unit 3080 that stores the load upper limit value. The load upper limit value is an upper limit value of the load allowed by the information collection system 2000.

  Further, the collection rule storage unit 5000 according to the second embodiment indicates the collection rule in association with the collection load. The collection load corresponding to the collection rule indicates the load applied to the information collection system 2000 by acquiring the second information performed based on the collection rule.

  FIG. 11 is a diagram illustrating a collection rule table according to the second embodiment. The collection rule table in FIG. 11 is referred to as a collection rule table 400. The record ID 402 to the application count 416 in the collection rule table 400 are the same as the record ID 202 to the application count 216 in the collection rule table 200, respectively. Unlike the collection rule table 200, the collection rule table 400 has a collection load 418. The collection load 418 of each record indicates the collection load applied to the collection rule table 200 when the second information is collected based on the collection rule indicated by the record.

  The collection rule acquisition unit 3060 according to the second embodiment acquires the collection rule so that the total value of the collection loads indicated by the currently applied collection rules is equal to or less than the load upper limit value.

  For example, the server device 3000 performs processing according to the flow shown in the flowchart shown in FIG. In step S202, the collection rule acquisition unit 3060 receives the “collection rule” corresponding to the first information acquired by the first information acquisition unit 3020 from the collection rule storage unit 5000 and the edge device 4000 that is the generation source of the first information. , Collecting load "combination. Hereinafter, these are expressed as collection rule i and collection load i, respectively. In step S204, the collection rule acquisition unit 3060 acquires a collection rule list that is a list of collection rules currently applied to each edge device 4000. In this case, the server device 3000 includes a rule list storage unit that stores a collection rule list.

  Steps S206 to S214 are loop processing A that is repeatedly performed. The loop process A is repeatedly performed while the condition “the sum of the collection load i and the total value of the collection loads included in the collection rule list is greater than the load upper limit value” is satisfied. In step S206, the collection rule acquisition unit 3060 determines whether or not to continue the loop process A. When the loop process A is continued, the process of FIG. 12 proceeds to step S208. On the other hand, when the loop process A is not continued, the process of FIG. 12 proceeds to step S216.

  In step S208, the collection rule acquisition unit 3060 determines whether there is a collection rule list having a lower priority than the collection rule i. If there is no collection rule having a lower priority than the collection rule i (step S208: NO), the processing in FIG. 12 ends. On the other hand, when there is a collection rule having a lower priority than the collection rule i (step S208: YES), the process of FIG. 12 proceeds to step S210. In step S210, the collection rule acquisition unit 3060 deletes one of the collection rules having a lower priority than the collection rule i from the collection rule list. In step S212, the collection rule acquisition unit 3060 stops applying the collection rule deleted from the collection rule list. That is, the collection of the second information based on this collection rule is stopped. Step S214 is the end of loop processing A. The process of FIG. 12 proceeds to step S206.

  In step S216, the collection rule acquisition unit 3060 adds “collection rule i, collection load i” to the collection rule list. In step S218, the collection rule acquisition unit 3060 acquires the second information based on the collection rule i.

  When the loop process A is finished and the process proceeds to step S216, the conditional expression shown in step S206 is satisfied. Therefore, even if the second information is collected according to the collection rule i, the load applied to the information collection system 2000 does not exceed the load upper limit value. Therefore, by performing the processing in the flow of FIG. 12, it is possible to prevent the load applied to the information collection system 2000 from exceeding the load upper limit value.

  Note that the flow of processing performed by the server device 3000 of the second embodiment is not limited to the flow of FIG. For example, in the case of FIG. 12, the collection rule for canceling the application is determined based on the priority of the collection rule. However, the collection rule acquisition unit 3060 may cancel the application in order from the collection rule with the earliest time when the application of the collection rule is started, for example. Further, for example, the collection rule acquisition unit 3060 may determine a combination of collection rules for which application is to be stopped so that the number of collection rules for which application is to be stopped is minimized. This combination is aimed at minimizing the number of collection rules, and can be calculated by solving an optimization problem that restricts that the total load does not exceed the load upper limit value.

  Furthermore, the server device 3000 may not use the collection rule list. For example, the server apparatus 3000 may store a total load value that is a total load applied to the information collection system 2000 according to the currently applied collection rule, and may use this total load value. In this case, the collection rule acquisition unit 3060 does not collect the second information based on the collection rule i when the sum of the load total value and the collection load i is larger than the load upper limit value. Conversely, when the sum of the total load value and the collected load i is equal to or less than the load upper limit value, the second information is collected based on the collection rule i. If the collection rule list is not used, it is difficult to stop the application by selecting an appropriate collection rule being applied. However, since it is not necessary for the server device 3000 to store the collection rule list, it is possible to reduce the capacity of the storage and memory required for the server device 3000. In addition, since it is not necessary to perform a process such as selecting a collection rule to be deleted from the collection rule list, the time required for the process necessary to start collecting the second information is shortened.

<Upload upper limit value>
Furthermore, the server device 3000 according to the second embodiment may have a function of updating the load upper limit value stored in the upper limit value storage unit 3080. There is a possibility that the load upper limit value that is the upper limit value of the load that the information collecting system 2000 can tolerate may fluctuate. For example, since there is information exchanged via the communication network 10 in addition to the second information, the load on the communication network 10 may vary due to the exchange. Therefore, the server device 3000 acquires information related to the load of the information collection system 2000 and updates the load upper limit value according to this information.

  FIG. 13 is a block diagram illustrating an information collection system 2000 according to the second embodiment having a function of updating the load upper limit value. In FIG. 13, arrows indicate the flow of information. Further, in FIG. 13, each block represents a functional unit configuration, not a hardware unit configuration.

  The server device 3000 includes a load information acquisition unit 3090 and an upper limit value update unit 3110. The load information acquisition unit 3090 acquires load information that is information related to the load of the information collection system 2000.

  For example, the load information is information indicating the load of the communication network 10. In this case, the information collection system 2000 includes a network load measuring unit that measures the load on the communication network 10. The network load measurement unit may be provided inside the server device 3000, may be provided inside the edge device 4000, or may be a device separately provided for network measurement. Since the method of measuring the network load at the end host and the method of measuring the network load by a device installed between the end hosts are both known techniques, detailed description thereof is omitted.

  In addition, for example, the load information indicates the load of the server device 3000 or the load of the edge device 4000. The load of the server device 3000 and the edge device 4000 is represented by, for example, the usage rate of the computer resources that they have. The load information of the edge device 4000 may be collected together with the first information, or may be collected separately.

  The upper limit value update unit 3110 updates the load upper limit value stored in the upper limit value storage unit 3080 based on the load information. For example, assume that the network load is used as the load information. In this case, the load upper limit value represents the network bandwidth of the communication network 10 that can be used for collecting the second information. The collection load corresponding to the collection rule represents the network bandwidth used by the collection of the second information based on the collection rule. Then, the load upper limit value is calculated by subtracting the network bandwidth used for purposes other than the collection of the second information from the maximum network bandwidth of the communication network 10. The network bandwidth used other than the collection of the second information is calculated based on the load information. Note that the load upper limit value may be calculated by further subtracting a predetermined margin from the value calculated by the above calculation method.

<Action and effect>
According to the present embodiment, the second information is collected in consideration of the load on the information collection system 2000. Specifically, the collection rule to be applied is determined so that the total collection load of the collection rules to be applied is equal to or less than the load upper limit value. By doing so, it is possible to prevent the information collection system 2000 from being overloaded by the collection of the second information.

  As described above, the information collection system 2000 according to the second embodiment may have a function of updating the load upper limit value. By doing so, it is possible to determine a collection rule for collecting the second information in consideration of the load on the information collection system 2000 other than the collection of the second information. Therefore, it is possible to prevent the communication network 10 from being heavily loaded by collecting the second information with a higher probability.

[Embodiment 3]
FIG. 14 is a block diagram illustrating an information collection system 2000 according to the third embodiment. In FIG. 14, arrows indicate the flow of information. Further, in FIG. 14, each block represents a functional unit configuration, not a hardware unit configuration.

  The edge device 4000 according to the third embodiment acquires a rule regarding the generation of the first information from the outside. Details will be described below.

<Generation rule storage unit 6000>
The information collection system 2000 according to the third embodiment includes a generation rule storage unit 6000. The generation rule storage unit 6000 stores generation rules. The generation rule is associated with the first information and the edge device 4000 that generated the first information, and indicates a rule regarding generation of the first information.

  For example, the generation rule indicates a method for generating the first information and the content of the first information. For example, it is assumed that the first information is information indicating whether an abnormality has occurred in the edge device 4000 or the monitoring target device of the edge device 4000. In this case, the generation rule indicates a rule for determining whether or not an abnormality has occurred in the edge device 4000 or the monitoring target device of the edge device 4000. For example, this rule indicates a rule of “which computer resource usage rate is in which range is determined as abnormal” for the usage rate of each computer resource. Further, for example, this rule is a rule of “Which variable value is in what range and in which range the value is determined as abnormal” in the software operating on the edge device 4000 or the monitoring target device of the edge device 4000. Show.

  Further, it is assumed that the generation rule indicates the content of the first information. In this case, the first information generation unit 4020 generates first information indicating the contents indicated in the generation rule. For example, in this case, the generation rule indicates which element is included in the first information or which parameter is included in the first information in the edge device 4000 or the monitoring target device of the edge device 4000.

  The generation rule storage unit 6000 may be provided inside the server device 3000 or may be provided outside the server device 3000. The method for realizing the generation rule storage unit 6000 is the same as the method for realizing the collection rule storage unit 5000.

<Server device 3000>
The server device 3000 includes a generation rule acquisition unit 3120 and a generation rule transmission unit 3140. The generation rule acquisition unit 3120 acquires from the generation rule storage unit 6000 the first rule acquired by the first information acquisition unit 3020 and the generation rule corresponding to the edge device 4000 that generated the first information. The generation rule transmission unit 3140 transmits a generation rule corresponding to the edge device 4000 to the edge device 4000.

<Edge device 4000>
The edge device 4000 includes a generation rule reception unit 4120 that receives a generation rule. In addition, when the generation rule reception unit 4120 receives a generation rule, the first information generation unit 4020 of Embodiment 3 generates first information using the generation rule.

<About the first information generated before receiving the generation rule>
The generation rule acquisition unit 3120 acquires a generation rule corresponding to the first information. Therefore, the edge device 4000 needs to generate the first information at a time before acquiring the generation rule from the generation rule transmission unit 3140. Therefore, for example, a default generation rule is set for each edge device 4000. Then, the first information generation unit 4020 generates the first information according to the default generation rule until the generation rule reception unit 4120 acquires the generation rule from the generation rule transmission unit 3140.

<Generation rule table 300>
FIG. 15 is a diagram illustrating information stored in the generation rule storage unit 6000 in a table format. The table shown in FIG. 15 is referred to as a generation rule table 300. Each record of the server device 3000 indicates a record ID 302, a signal set 306, and a generation rule 308. The record ID 302 is a record ID. The signal set 306 indicates a combination of “edge device 4000, first information” associated with the generation rule. Similarly to the signal set 206 in FIG. 9, the signal set 306 may indicate a plurality of combinations of “edge device 4000, first information”.

  The method by which the generation rule acquisition unit 3120 acquires the generation rule from the generation rule table 300 is the same as the method by which the collection rule acquisition unit 3060 acquires the collection rule from the collection rule table 200.

  The record generation rule 308 in the first row in FIG. 15 is an example showing the contents (parameter combinations) to be included in the first information as a rule for generating the first information. The record in the second row in FIG. 15 is an example of a conditional expression for determining whether or not the edge device 4000 has an abnormality as a rule for generating the first information. In this conditional expression, when the value of parameter x satisfies the condition 20 <x <40, the edge device 4000 determines that it is normal (OK), and the value of parameter x does not satisfy the condition 20 <x <40. In this case, the edge device 4000 is a conditional expression for determining that an error has occurred.

<Process flow>
FIG. 16 is a diagram illustrating a flow of processing executed in the information collection system 2000 according to the third embodiment. In step S302, the first information generation unit 4020 generates first information. In step S304, the first information acquisition unit 3020 acquires the first information. In step S306, the generation rule acquisition unit 3120 acquires from the generation rule storage unit 6000 the generation rule corresponding to the first information acquired in step S304 and the edge device 4000 that is the generation source of the first information. In step S <b> 308, the generation rule transmission unit 3140 transmits a generation rule to the edge device 4000. In step S310, the edge device 4000 receives the generation rule. In step S312, the first information generation unit 4020 generates first information based on the generation rule.

<Action and effect>
In the present embodiment, the first information generation unit 4020 generates the first information based on the generation rule. Therefore, the generation rule of the first information by each edge device 4000 can be centrally managed by the generation rule storage unit 6000. Therefore, management of the first information generation rule (change of the generation rule, etc.) is facilitated.

  Further, by determining the first information generation rule in association with the first information and the edge device 4000 that generated the first information, according to the state of the edge device 4000 or the monitoring device of the edge device 4000, The generation rule of the first information can be determined flexibly.

  Furthermore, the edge device 4000 only needs to generate the first information according to the generation rule acquired from the outside, and it is not necessary to determine the generation rule of the first information inside the edge device 4000. Therefore, the mounting of the edge device 4000 can be simplified, and the cost and size of the edge device 4000 can be reduced.

  As mentioned above, although embodiment of this invention was described with reference to drawings, these are illustrations of this invention, The combination of the said embodiment and various structures other than the said embodiment can also be employ | adopted.

This application claims the priority on the basis of Japanese application Japanese Patent Application No. 2013-243299 for which it applied on November 25, 2013, and takes in those the indications of all here.
