Description

  The present invention relates to a monitoring device, a monitoring system, and a monitoring method for monitoring abnormal states such as illegal dumping and theft of home appliances.

  In recent years, for example, precious metals, vehicles, and monitoring devices equipped with positioning means and communication means using GPS (Global Positioning System), PHS (Personal Handyphone System), etc., have been attached to valuables such as ATM (Automated Teller Machine). If the valuables are stolen, the monitoring device notifies the monitoring center of the position information of the valuables, and the monitoring center tracks the position of the valuables. Provided positioning service.

In addition, the provision of a wide-area ubiquitous network technology capable of wireless access of several kilometers and accommodating terminals with low power consumption is expected to provide an inexpensive positioning service (see, for example, Non-Patent Document 1). .

  However, when a monitoring device built in a home appliance or the like placed in an abnormal state such as illegal dumping realizes a positioning service that notifies the monitoring center of location information of the home appliance or the like, a conventional monitoring device Does not have a means to detect an abnormal state, so the timing information to be notified is not known, and even if the home appliances are in a normal state where they are not dumped illegally, the location information is sent to the upper monitoring device of the monitoring center. There was a problem of notification. For this reason, there is a problem that the host monitoring device that is notified of the position information from the monitoring device in the normal state increases the communication cost.

  In addition, because the monitoring device notifies location information at an unnecessary timing, power is wasted, and illegally dumped home appliances etc. are illegally dumped because the external power supply is cut off When a monitoring device such as a home appliance placed in an abnormal state needs to actually perform positioning and position notification, there is a problem that power necessary for notification of position information cannot be obtained.

  The present invention has been made in view of the above-described points, and a monitoring device incorporated in advance in a home appliance or the like placed in an abnormal state such as theft or illegal dumping correctly detects the abnormal state of the home appliance or the like. It is an object of the present invention to provide a monitoring device that makes communication costs and power consumption more efficient and notifies the position information to a higher-level monitoring device such as a monitoring center.

The power supply is built in when there is no power supply from the outside. A power supply unit, a positioning unit that outputs a positioning result by a predetermined positioning means, a detection unit that detects the presence or absence of the power supply and outputs the detection result, and the detection result indicates that there is no external power supply And a transmitter that transmits the positioning result.

  In addition, the present invention is a monitoring apparatus including the transmission unit that transmits an identifier indicating the monitored apparatus.

  The present invention also provides a monitored device that monitors the presence or absence of external power supply, a built-in power supply that is built in the monitored device and that supplies power when there is no external power supply, and a predetermined positioning A positioning unit that outputs a positioning result by means, a detection unit that detects the presence or absence of the power supply, and outputs a detection result, and the positioning result indicates that there is no external power supply. And a second monitoring device that receives the positioning result. A monitoring system comprising: a transmission unit that transmits the positioning result; and a second monitoring device that receives the positioning result.

  Further, the present invention is a processing method performed by a monitoring device built in a monitored device that is monitored for the presence or absence of external power supply, and the power supply is provided when the built-in power supply unit has no external power supply. A step in which the positioning unit outputs a positioning result by a predetermined positioning means, a step in which the detection unit detects the presence or absence of the power supply, and outputs a detection result, and a transmission unit in accordance with the detection result And a step of transmitting the positioning result when it is indicated that there is no external power supply.

  According to the present invention, a monitoring device attached in advance to a home appliance or the like placed in an abnormal state such as theft or illegal dumping detects that the external power supply has been stopped, and uses this as a trigger for the home appliance etc. The position information is notified to a host monitoring device such as a monitoring center. For this reason, only a monitoring device such as a home appliance placed in an abnormal state notifies the host monitoring device of the position information, so that the monitoring device is improved in communication cost and power consumption.

  An embodiment for carrying out the present invention will be described. FIG. 1 is a diagram showing a monitoring system according to an embodiment of the present invention. The monitoring system includes a monitoring device 1, a monitored device 10, an external power supply device 20, and a host monitoring device 30. The monitored device 10 is a device to be monitored from the monitoring device 1 such as a home appliance, and includes the monitoring device 1. The monitoring device 1 includes a control unit 2, a power supply relay unit 3, a built-in power supply unit 4, a positioning unit 5, and a transmission unit 6. The host monitoring device 30 is provided in a monitoring center (not shown).

  The external power supply device 20 is provided outside the monitored device 10 and the monitoring device 1, and supplies power to the monitored device 10 and the monitoring device 1 via the power supply relay unit 3. The power supply relay unit 3 relays power supplied from the external power supply device 20 or the built-in power supply unit 4 and supplies power to the monitoring device 1 and the monitored device 10 via the power supply line 7. A power supply line from the power supply relay unit 3 to the monitored device 10 is not shown. In response to a notification request from the control unit 2, the power supply relay unit 3 controls whether power is supplied to the power supply relay unit 3 from the external power supply device 20 via the communication line 8 between the control unit power supply relay units. Notify part 2. The power supply from the external power supply device 20 may be, for example, power supply from a power socket (power outlet) installed in a house or the like.

  The built-in power supply unit 4 is provided in the monitoring device 1 and supplies power to the monitoring device 1 via the power supply relay unit 3. The built-in power supply unit 4 detects whether or not power is supplied from the external power supply device 20 to the power supply relay unit 3. If power is not supplied, monitoring is performed via the power supply relay unit 3 instead of the external power supply device 20. Power is supplied to the device 1. The built-in power supply unit 4 may be provided not in the monitoring device 1 but in the monitored device 10 to supply power to both the monitored device 10 and the monitoring device 1 via the power supply relay unit 3. In this case, by providing a plurality of built-in power supply units 4, at least one built-in power supply unit 4 may be secured as a dedicated built-in power supply for the monitoring device 1 so as to reliably obtain power necessary for notification of position information and the like. . Further, the built-in power supply unit 4 may be charged from the external power supply device 20 via the power supply relay unit 3.

  When placed in an abnormal state such as theft or illegal dumping, the monitored device 10 is not connected to the external power supply device 20 because it is moved from a predetermined installation location, and thus power is not supplied from the external power supply device 20. . In order to determine the abnormal state of the monitored device 10 due to theft or illegal dumping, the control unit 2 requests the power supply relay unit 3 at a predetermined cycle, for example, to make the above notification. When the control unit 2 is notified from the power supply relay unit 3 that there is no power supply from the external power supply device 20 as a response to this request, the control unit 2 determines that the monitored device 10 is in an abnormal state. Note that the control unit 2 may determine that the monitored device 10 is in an abnormal state even when there is no notification (response) within a predetermined time after the control unit 2 requests the power relay unit 3 for notification. .

  When determining that the monitored apparatus 10 is in an abnormal state, the control unit 2 outputs a positioning process execution request and a position information notification request as a positioning result to the positioning unit 5. The control unit 2 notifies the transmission unit 6 of data including the position information notified as a response from the positioning unit 5 and the identifier stored in advance for identifying the monitored device 10.

  When the positioning processing execution request and the position information notification request are input from the control unit 2, the positioning unit 5 is, for example, a satellite positioning such as a GPS or a quasi-zenith satellite system (Quasi-Zenith Satellites System), or a wireless LAN. Positioning processing is executed by positioning means using electric field strength such as (Local Area Network) or PHS, and the positioning result including the position information of the monitoring device 1, that is, the monitored device 10 is notified to the control unit 2. Note that the positioning unit 5 may execute a positioning procedure using a base station of a portable information terminal or a stay-type flying body (high altitude unmanned aircraft, airship, helicopter, etc.).

  When the transmission unit 6 is notified of the abnormal state data including the position information and the identifier of the monitored device 10 from the control unit 2, the higher level monitoring device installed in the monitoring center or the like (not shown) is notified of the notified abnormal state data. 30 for example via a wireless network. Upon receiving the abnormal state data, the host monitoring device 30 recognizes that the monitored device 10 and the monitored device 10 are in an abnormal state, and executes a predetermined operation such as reporting.

  FIG. 2 is an operation sequence diagram of the monitoring system according to the embodiment of the present invention. The power relay unit 3 is supplied with power from the external power supply device 20. The control unit 2 makes a power supply confirmation request to the power supply relay unit 3 (step S1). The power relay unit 3 notifies the control unit 2 that power is being supplied from the external power supply device 20 (step S2). The operation from step S1 to step S2 may be repeated a plurality of times.

  For example, since the monitored device 10 has been placed in an abnormal state such as illegal dumping, the power supply socket (power outlet) installed in the house or the like is unplugged, and power supply from the external power supply device 20 to the power relay unit 3 is stopped. (Step S3). When the built-in power supply unit 4 detects that the power supply from the external power supply device 20 to the power supply relay unit 3 is cut off, the built-in power supply unit 4 supplies power from the built-in power supply unit 4 (step S4).

  The control unit 2 makes a power supply confirmation request to the power supply relay unit 3 (step S5). The power supply relay unit 3 notifies the control unit 2 that power is supplied from the built-in power supply unit 4. Since the power supply relay unit 3 is supplied with power from the built-in power supply unit 4, the control unit 2 determines that the monitored device 10 is in an abnormal state (step S6). Note that the operations from step S5 to step S6 may be repeated a plurality of times.

  The control unit 2 requests the positioning unit 5 to execute the positioning process and notify the position information that is the positioning result (step S7). The positioning unit 5 executes a positioning process (step S8). The positioning unit 5 notifies the control unit 2 of the positioning result including the position information of the monitoring device 1, that is, the monitored device 10 (step S9). The control unit 2 notifies the transmission unit 6 of abnormal state data including the notified position information and the identifier of the monitored device 10 (step S10). The transmission unit 6 transmits the notified abnormal state data to the higher-level monitoring device 30 (step S11). Upon receiving the abnormal state data, the host monitoring device 30 recognizes the position of the monitored device 10 and that the monitored device 10 is in an abnormal state, and executes a predetermined operation.
