Description

Reprogrammable Remote Sensor Monitoring System

Background of the invention

The present invention relates to a portable, real-time, reprogrammable sensor monitoring system.

For more than fifty years, governments have tracked the movement of vehicles or troops using active or passive detection systems. Smart communications already use multimillion-dollar satellite-borne sensors containing high-resolution cameras, infrared and radio direction-finding equipment to covertly monitor areas of interest. It is only in recent years that economies of scale and breakthroughs in production have allowed derivatives of this technology to be used in commercial applications.

An early commercial application was a satellite-borne vehicle tracking system using communication satellites in synchronous (co-located) orbits above the Earth. These satellites all use terminal antenna packages, are about the size of a suitcase, and have a considerable price tag, resulting in limited use in large trucking companies. In order to reduce the price and the size of the terminal to the average consumer, two developments have been made. One development uses a radio network using low-Earth orbit satellites, and the second uses local cellular capabilities and other existing terrestrial radio networks. Using these new capabilities, the mobile asset monitoring and tracking market has grown to include all surface modes of transportation. The current focus is on vehicle safety and recovery by vehicles. Falling communication costs also allow the market to expand into small fleet management, as well as navigation, traffic control and roadside assistance.

While these abilities are valuable, the inventors believe that they have failed to pay personal attention to a problem of increasing social importance that nearly everyone encounters in their lives. This problem is based on the need to monitor distant persons or other subjects who are expected to move normally but may not be able to do so; and, if the subject is not moving normally, notification or corrective action must be taken. In commonly encountered situations, an elderly or infirm relative wants to lead a normal, independent life, but due to age or illness the relative is unable to do so. Concerned people can call or visit again and again, but such checks can be unreliable because relatives may suddenly become ill long before the next checkup. In addition, relatives and interested persons may not be able to recognize the signs of an unexpected accident. Too frequent calls or visits may make relatives uncomfortable.

There needs to be a way to allow the subject to perform the monitoring and communication required in abnormal or emergency situations while allowing normal activity. The present invention fulfills such a need and provides related conveniences.

Summary of the invention

The present invention provides an apparatus and method for monitoring living or inanimate objects from a distance. The method of the present invention allows monitoring of the state and position of the subject, in some cases with the cooperation of the subject. The nature of monitoring can vary according to the needs of the environment.

According to the invention, an apparatus for remotely monitoring and estimating the state of an object comprises a portable monitoring unit comprising at least one automatic sensor associated with the object, a position determination device made as a portable unit; and a sensor interface unit. The sensor interface unit includes a reprogrammable microprocessor with an active state and a standby state. The microprocessor can change from the inactive state to the active state in response to the activation parameters of any set of operating states, including at least one state preselected by an automatic sensor, a request signal from an external source, and a human condition The status signal of the lower object. The microprocessor communicates with at least one automatic sensor and position determination device. The sensor interface unit also includes a communication device interface in communication with the microprocessor, a first transceiver of the communication device in communication with the communication device interface, and a first terminal for the microprocessor, the communication device interface, and the communication device and also to the portable unit A power supply that provides power to any other component that requires power.

One or more sensors are selected as appropriate for the object and the reason for monitoring the object. For example, sensors may include audio/video sensors, biostat sensors, chemical sensors, weather sensors, motion sensors, electromagnetic sensors, seismic sensors, or device sensors.

The location determining means may be selected to determine the absolute location of the portable monitoring unit, or the relative location of the portable monitoring unit to other locations. The position determining means is preferably a Global Positioning System (GPS) receiver, but other types of means such as triangulation means or cell phone based means could also be used.

In addition, there is a central monitoring device with a second terminal of the communication device, and desirably a display in communication with the second terminal of the communication device and a computer for receiving and processing information from the sensor interface unit via the communication device. A central monitoring facility is typically capable of maintaining the necessary communications with many portable monitoring units. The central monitoring unit may be portable and may contain its own position determination functionality either absolute or relative to the position of each portable monitoring unit.

In operation, the microprocessor is programmed with a set of start-up parameters for the working state, and then the microprocessor enters the standby state. The microprocessor enters the operational state in response to occurrence of any of the operational state's enabling parameters. The microprocessor gets the status of the object from the automatic sensors and the position of the portable unit from the position determining means and sends status messages to the central monitoring means through the communication means.

The microprocessor of the sensor interface unit is equipped with a unique unit identifier whose central monitoring means addressing data, initialization data and rules used by each sensor are loaded or accessed into the unit. The sensor interface unit may be configured on a sensor-to-sensor basis to transmit all sensor data received in operation, or all data meeting some predetermined criteria such as time window, decibel value or signal threshold. Data transfer from the sensor interface unit may be initiated manually, activated by a control signal from a central monitoring device, or automatically in response to receipt of specific input from one or more of the connected sensors. In one embodiment, the sensor interface unit includes a tone or visible light generator component which is activated by a call from a central monitoring device, and means for activating/deactivating the component.

the central monitoring unit comprises a second terminal of communication means which allows the central monitoring unit to communicate with any one of a plurality of portable monitoring units to uniquely identify each unit and data concerning its configuration and use, to process received data, And display the processed data to the operator of the central monitoring device. Location data can be displayed on a map or plotted with distance and direction to a known address or location. The central monitoring device includes the ability to transmit received data to other devices.

Thus, the present invention handles events from the aspect of the monitored object. The event at the portable receiving unit is perceived. The central monitoring unit can make periodic status inquiries to the portable receiving unit. Status inquiries can be made in an automatic response mode without the subject's knowledge or involvement, such as a sensor periodically monitoring when the subject is sleeping or even when the subject is awake, so as to minimize interruptions. The portable monitoring unit may be configured to access the central monitoring facility periodically or in response to preselected sensor readings. Such status queries may also be made to ask a subject to respond, eg, to determine whether an awake subject is mentally able to respond. In the case of a human, the subject may also respond to a call from the portable monitoring unit or the subject actively sends a signal such as "Hi" to the central monitoring device. If no "I'm OK" signal is received, the system determines the location of the portable monitoring unit, reviews available sensor data (such as biometric information or sensor information on medical devices used by the person, such as infusion pumps), and sends Provide information to relevant personnel, or call medical practitioners as appropriate.

A single central monitoring unit can monitor many different portable monitoring units, each configured differently or reconfigured as desired. An important feature of the present invention is the ability to change (ie reprogram) the operating parameters, as well as change the functionality of the portable monitoring unit for different needs. Human medical and status applications are described in the preceding paragraphs. The same device but different sensors can be used to track and monitor inanimate objects, such as expensive items in a shipment. In this case, the sensor can indicate the state of the item, such as temperature, humidity or movement, or the associated state of the equipment such as cooling or heating.

Other features and advantages of the invention will become apparent from the following more detailed description of preferred embodiments of the invention, which illustrate, for example, the gist of the invention, with reference to the accompanying drawings. But the scope of the present invention is not limited to the preferred embodiment.

Detailed description of the invention

As shown in Figures 1 and 2, the apparatus for remotely monitoring and assessing the status of a subject comprises a portable monitoring unit 12 and a central monitoring device 14, which may communicate via a radio communication link. FIG. 1 depicts a preferred embodiment of apparatus 10 . FIG. 2 depicts a communication link configuration with a plurality of portable monitoring units 12 and a central monitoring device 14 .

The portable monitoring unit 12 includes a sensor interface unit 20, represented by a bus structure, within which is a microprocessor 22 having a plurality of inputs and outputs. Communication of the microprocessor 22 with the radio communication link 16 , and thus with the central monitoring device 14 , takes place via the communication device interface 24 of the radio communication link 16 and the first transceiver 26 . Information is assembled by one or more sensors 28 . The radio communication link 16 is preferably a digital radio communication link, but an analog link could also be used instead. The sensors 28 may include internal sensors 28a installed within the portable monitoring unit 12 and/or external sensors 28b connected to the portable monitoring unit through a suitable external interface 30 . (In FIG. 1, the external interface 30 is depicted as part of the portable monitoring unit 12, but it could be external to the portable monitoring unit.) The external sensor 28b can be any type of sensor that can be connected to the microprocessor 22 through the interface 30 . For example, interface 30 may be a standard serial or parallel interface, a PCMCIA interface, or an Ethernet interface. An external programming device or other device may also be connected to the microprocessor 22 through a suitable external interface 30 .

An optional manual input device 32 in communication with the microprocessor 22 is accessible from the outside of the portable monitoring unit 12 to allow a user or subject of the portable monitoring unit to provide information to the microprocessor 22 . The manual input device 32 can be as simple as a switch, such as a push button switch, or more complex as a keyboard. A display 34, such as a liquid crystal display, and an audio and/or visual communication device 36, such as a tone generator, speaker, or pulsed light source, may optionally be provided to signal the user of the portable monitoring unit 12 for additional response. . An external port 37 such as a serial or parallel communication port is provided to allow input of information or reprogramming instructions to the microprocessor 22 in place of the portable monitoring unit 12 . (Portable sensors can also be connected via the external port 37). Manual input device 32, display 34, audio and/or visual communication device 36, and external port 37 are optional for specific needs.

Microprocessor 22 may be a chip package (MCP) such as the currently available Vadem VG330, Advanced Micro Devices AMD Elan SC400, NEC HHT-ASSP, or ZF Microsystems SMX/386. The microprocessor includes a power management unit that allows the microprocessor to be placed in an inactive state or put into an active state by appropriate signals. Power management can protect the power supply 42 . The microprocessor is typically configured with memory 44, which may be random access memory, read-only memory, mass storage, or any combination of these types of memory. This memory may be shared with other elements of the portable monitoring unit 12 . The first transceiver 26 may be a single board digital radio module with a suitable interface 24, such as the WIT915 or WIT2500M sold by Digital Radio Corporation. The first transceiver 26 has its own power management unit which allows the transceiver to be placed in a standby state or put into an active state with appropriate signals.

Position determination means 38 are provided so that the position of the portable monitoring unit 12 can be determined. The location determining means 38 is preferably a Global Positioning System (GPS) receiver having an antenna common to the first transceiver 26 . The GPS receiver may be a MicroTracker LP global positioning system receiver module commercially available from Rockwell Semiconductor Systems. Other types of position determination means 38 such as those based on cellular cell-site position triangulation, LORAN, etc. may also be used.

A power source 42 , such as a battery, provides power to components of the portable monitoring unit 12 that require power, which may be any of the external sensor 28 b and the external interface 30 . In FIG. 1, power connections between elements providing power and the power supply 32 are indicated by "PS" to avoid obscuring data communication paths by drawing interconnections.

The central monitoring device 14 includes at least one second transceiver 50 of the radio communication link 16 to establish communication between the first transceiver 26 of the portable monitoring unit 12 and the central monitoring device 14 . Typically, the central monitoring device 14 also includes a terminal 52 having a communication device interface 58 connected to the second transceiver 50 and a connection point to a display 54 which can be viewed with an operator 56 . Terminal 52 may be a purely manual system, or preferably, it may be more complex as described. Within this more complex terminal 52 there is a computer 60 which communicates with the display 54 and with the portable monitoring unit 12 and monitors its operation in the manner discussed below. A position determination device 62 may also be provided for the central monitoring device 14, especially if the central monitoring device is portable or portable and its position must be determined. The position determination device 62 has an antenna 64 shared with the second transceiver 50 . Typically, compatible position determining devices 38 and 62 are selected. If, for example, the position determining device 38 is an autonomous GPS receiver, typically the position determining device 62 is also a GPS receiver. On the other hand, position determination techniques may utilize triangulation, time-of-flight, or other types of measurements that require coordination between position determining devices 38 and 62, which are then selected by the preferred technique.

Figure 2 depicts the installation of device 10 in an existing communication link, and its integration with other similar units. In this case, the device 10 is incorporated into a cellular telephone communication system having a plurality of cell locations 70 , here depicted as two cell locations 70 . Each cell site 70 communicates with a central telephone office 72 (eg, MTSO or Mobile Telephone Switching Office) via typically a ground line. Each cell location 70 is in radio communication with one or more portable monitoring units 12, depicted here as two portable monitoring units. Each cell location 70 is in radio communication with one or more central monitoring devices 14 . Two types of such central monitoring devices are described, central monitoring device 14a in radio communication with cell site 70, and central monitoring device 14b in land-based communication with cell site 70 through central telephone office 72. Central monitoring device 14a may typically be a mobile unit, while central monitoring device 14b may typically be a stationary unit. Such a configuration allows the central monitoring device 14 to be used in a variety of applications and to monitor many different portable units 12 of the same or different kinds and applications.

When there are two or more portable monitoring units 12 as shown in FIG. One unit 12 communicates.

Figure 3 depicts the practice of the invention. Set the operational equipment, the number is 80. The preferred device is device 10 described above. Program the microprocessor with a set of instructions for general operation and start-up parameters, number 82. Programming may be provided by the central monitoring device 14 or by a separate source connected through port 37 or external interface 30 . The programming features are discussed below. The microprocessor first enters into work to find the occurrence of the start parameter of any working state, and if the start parameter does not occur, it becomes the standby state, numbered 84. The microprocessor becomes (or remains) active, number 86, if there is any kind of start-up parameter, or any start-up parameter of any kind of start-up condition happens to occur. The microprocessor obtains the state of the object and its position, item 88 , and reports this information via the communication link 16 to the control monitoring means 14, item 90 . The central monitoring unit analyzes and reports the information and takes appropriate action, No. 92.

Thereafter, when conditions can be warranted, the microprocessor can be reprogrammed, number 94. Reprogramming can occur from the above-mentioned source, namely at the location of the portable monitoring device, or from a location remote from the central monitoring device via the radio communication link 16 .

FIG. 4 depicts the process flow for the preferred embodiment of the portable monitoring unit 12 for initializing when the sensor interface unit 20 is powered on and then formatting and sending data received from one or more sensors 28. . When power is applied, the microprocessor 22 loads the portable receiver unit application program from non-volatile memory, loads the unit start-up parameters from memory, and enters an operational state. Once the microprocessor is operational, it reads the memory, then monitors the sensor 28, port 37, communicator interface 24, and manual input 32 for activation. If there is no activity on sensor 28, port 37 or manual input 32 for the time specified by the operating parameters, the microprocessor places communicator interface 24 in an inactive state. A signal from any of source 28, port 37, communicator interface 24, or manual input 32 causes the microprocessor to return to the start-up state. If the signal is from the manual input 32, the process described in FIG. 5 follows; if the signal comes from the communication device interface 24, the process described in FIG. 6 follows. If the signal comes from port 37, and the required service enters the administrative state, then the process described in FIG. 7 follows. If the source of the signal is a sensor 28 or port 27 connected to a sensor, and the job required is to transmit data to the control monitoring device 14, then the first transceiver 26 is powered. When the first transceiver 26 is powered on, a connection is established with the central monitoring device 14 via the communication link 16 . The microprocessor 22 formats the data received from the sensors 28 and transmits it to the central monitoring device 14 . When this data is received, the central monitoring facility 14 processes the received data and stores it in a database associated with the sending portable monitoring unit 12 . The operator 56 is notified of receipt of the data and provided with an opportunity to display the data, along with locally stored reference information pertaining to the sending portable receiving device 12, for review and appropriate action.

FIG. 5 depicts the process flow when a subject wants to initiate a transfer from the manual input device 32 of the portable monitoring unit 12 to the central monitoring device 14 . Depending on the type of manual input device, communication may be direct (such as a panic button signal) or involve the use of the display 34 . In the latter case, the microprocessor 22 activates the display 34 and displays a menu for the object. Object selects options from a menu. The microprocessor determines the service required and the information to be sent, and turns on the power of the first transceiver 26 . The microprocessor determines what action to take from the type of message requested and the rules associated with the current configuration and operating parameters. If data conversion is required, the microprocessor determines the required operation for each applicable interface based on the sensor interface unit 20 and operating parameters. As needed, the microprocessor activates the connected device and sends service requests to it. The microprocessor reads the data buffer associated with each applicable interface and, upon receipt of the required data, prepares a formatted message and places the message in the queue of the first transceiver 26 . If the request is an emergency call or communication detection, an instant connection is established with the central monitoring device and a prioritized formatted message is placed in the transmission queue. When the first transceiver is operational, a connection is established with the central monitoring device 14 via the communication link 16 . When a connection is established with the central monitoring device 14 , the communication device interface 24 reads the transmission queue and transmits all available messages to the central monitoring device 14 . As these messages are received, the central monitoring facility processes the received messages and stores the data in a database associated with the transmitting portable monitoring unit 12 . The operator 56 is notified of the receipt of the data and has the opportunity to display the data with locally stored relevant information pertaining to the sending portable monitoring unit 12 for review and appropriate action.

FIG. 6 illustrates when the operator 56 or terminal 52 wishes to query a specific portable monitoring unit 12, to monitor one or more sensors 28, to transmit a message to, or to change the configuration or application of the microprocessor by the portable monitoring unit 12. software processing. An operator or terminal places a call via communication link 16 . The connection request is detected by a low current receiver in the first transceiver 26 , which activates the entire first transceiver 26 and sends an enable signal to the microprocessor 22 . Once activated, the microprocessor acknowledges the call. The central monitoring unit 14 then transmits the service request information to the portable monitoring unit 12, and then to the microprocessor and its memory 44. If a status request is made to be responded to by the subject, the display 34 or audio/visual communicator operates until the subject responds via the manual input 32 . If the sensor interface unit is not properly configured when the request to be responded to by the object is made, a timeout occurs, completing the configuration. If the call requires data from a sensor 28, the microprocessor signals the sensor. When requested data is received from a sensor, a formatted message containing the data is prepared and transmitted. If reconfiguration (i.e., reprogramming) is required, the microprocessor stops all other inputs, displays on the display 34 an update message that is already in progress, receives the update message sent, performs the required work, and returns to the working state , put the update success/failure message into the transmission queue, and display the result on the display 34 . The updated status is transmitted to the central monitoring device 14 . The operator 56 is notified of the receipt of the data and has the opportunity to display the data for review and appropriate action with locally stored reference information pertaining to the sending portable monitoring unit.

In some cases, an external source (such as a personal computer connected to the portable monitoring unit 12 via port 37) is required. If port 37 is connected to an external sensor, and the information is data, then a readout is performed for sensor 28 in the same way as described for FIG. 4 . If the information is reprogrammed in the form of an application program update or new parameters, the portable monitoring unit 12 is powered on in the usual manner. The original application program is loaded into the microprocessor 22, the operating parameters are retrieved and set, and the sensor interface unit 20 is brought into operation. However, if the reprogramming is to be loaded through port 37, no input through other interfaces will be accepted. External sources load the reprogram through port 37. Reprogramming can be an entire new application program or new parameters of an existing program. By an operator request to perform administrative functions on a device fitted to one of the other interfaces, the microprocessor first verifies that the device is operational. If the device is inoperable, the microprocessor alerts the operation and waits for further commands. If the device is operational, the microprocessor indicates that it is ready to support supervisory functions and begins to schedule inputs and outputs to the device until it is signaled to stop by the operator or the device. If a reset command is received, the microprocessor closes all open files and returns to work. If it cannot return to a working state, an error message is displayed.

The procedures shown in Figures 4-7 provide a building block through which various queries, status checks, and reprogramming can be accomplished. For example, the central monitoring facility may periodically monitor the sensors 28 to determine the status of the object. Subjects may be required to "report" via periodic manual entry to demonstrate good mental health. If the subject is unable to report, the control monitoring device may initiate a call, activate the audio-visual device 36 and/or display 34 until the subject responds, and then ask the subject to perform a set of input responses via the manual input 32 to demonstrate good mental health . If the sensor information or the manual input of the object is not good, the control monitor 14 can report this fact and the apparent nature of the problem to the person concerned or call for help. is available, its data is automatically communicated with the central monitoring facility as part of a message message. Obviously, many different types of these procedures can be used to reprogram portable monitoring unit 12.

While specific embodiments of the present invention have been described for illustrative purposes, various modifications and enhancements can be made without departing from the spirit and scope of the invention. Accordingly, the invention is limited only by the appended claims.
