(Embodiment)
FIG. 1 is a diagram showing a system configuration including a measurement meter device and a security device in an embodiment of the present invention. In FIG. 1, this system configuration includes a management center (a gas company or the like) 100 that is a management system for collecting meter reading data and the like, a base station 200 connected to the management center 100 by a public telephone line network, and the like. The measurement meter device 300 is configured to communicate with the base station 200 via a wireless line.

  The measurement meter device 300 supplies gas to gas products such as a gas table, a hot water supply device, and a gas fan heater installed indoors, and when any abnormality is detected, the gas supply can be cut off. In this embodiment, the gas meter is assumed to be described. However, even a meter device that measures the flow rate of electricity, gas, water, or the like does not affect the invention, and the measurement meter device has a wireless communication function. Applicable in general.

In addition, a crime prevention device 400 is installed indoors. When the crime prevention device 410 attached to the window detects that an intruder has opened the window, the crime prevention device 410 communicates to the crime prevention device 400 by wireless communication. Since the security device 400 is wirelessly connected to the measurement meter device 300, the security device 400 notifies the security center via the measurement meter device 300 and the base station 200.

  Next, the internal configuration of the measurement meter device 300 will be described with reference to FIG. The measuring meter device 300 is provided with a measuring device 301 and measures the amount of gas used. The usage amount measured by the measuring device 301 can be confirmed by being displayed on the display unit 303 after being converted into a predetermined data format by the control means 302. Since the display unit 303 is provided at the position shown in FIG. 3, the user can check the flow rate value at any time.

  Further, the control unit 302 is connected to the communication unit 304. The control unit 302 converts the usage measured by the measuring device 301 into a predetermined data format and then transmits it to the communication unit 304. The communication unit 304 includes the antenna 305. The usage data is transmitted to the base station 200 via Further, the measurement meter device 300 uses an internal power supply 306 attached therein as a power supply source, and the control means 302 can check the remaining power capacity.

  The antenna 305 may be built in the measurement meter device 300 or may be configured by a glass antenna (a form in which an antenna line is embedded in the glass portion of the display unit 303). In addition, the communication unit 304 can be configured by a wireless communication module including an antenna. In this case, it is needless to say that it is not necessary to separately provide the antenna.

  The communication unit 304 is desirably as small as possible because it is installed inside the measurement meter device 300, and for example, a communication module is preferable. This communication module (communication unit 304) is a unit in which a wireless transmission / reception unit and a microcomputer unit are integrally sealed, and it is not necessary to arrange a microcomputer unit on a mounting board, thereby achieving a reduction in size of the communication unit 304. Yes. In wireless communication, specific low-power wireless communication using a 400 MHz band, a 1.2 GHz band, or a 2.4 GHz band is performed, and thus a transmission distance of several hundred meters can be obtained.

  Next, the internal configuration of the security device 400 will be described with reference to FIG. When the security device 400 receives intrusion alarm information from the security device 410 by the communication means 401, the control means 402 sounds an alarm from the alarm means 403 based on the intrusion alarm information. At the same time, the control unit 402 transmits the fact that the intruder alarm information has been received, that is, the fact that the intruder has entered from the outside, to the security center via the measurement meter device 300 and the base station 200. The security device 400 uses an internal power supply 404 attached therein as a power supply source, and the control unit 402 can check the remaining power capacity.

  Further, the internal configuration of the security device 410 will be described with reference to FIG. 3. When the security device 410 is installed in, for example, a window and the intrusion detection means 411 detects that the window has been opened, the control means 412 The communication means 413 wirelessly communicates the intrusion alarm information to the security device 400. The intrusion detection means 411 may be any means that can detect an intruder intrusion, such as a temperature sensor that detects the body temperature of the human body or an infrared sensor that senses the movement of the human body, in addition to the detection of the opening / closing of the window. Moreover, the crime prevention child machine 410 uses the internal power supply 414 attached in the inside as a power supply source, and the control means 412 can confirm the power capacity remaining amount.

  Next, the operation of the present embodiment will be described. In the present embodiment, when the measurement meter device 300 notifies the security center that the intrusion alarm information has been received via the base station 200, the remaining power of the internal power source 306 of the measurement meter device 300 is a predetermined amount (first 1) is transmitted directly to the base station 200, and when the remaining power of the internal power supply 306 is less than the predetermined amount, it is transmitted to other measurement meter devices installed in neighboring houses. Is transmitted from the measurement meter device to the base station 200.

Therefore, when the control means 302 receives an intrusion alarm signal from the crime prevention device 400 (step 401), it is checked whether or not the current remaining power of the internal power supply 306 is equal to or less than a first predetermined amount (step 402). . If the remaining power of the internal power supply 306 is equal to or less than the first predetermined amount, the measurement meter device 300 has received an intrusion alarm signal from another measurement meter device installed in a neighboring house. Notification is made (step 403), and other measurement meter devices transmit to the base station 200 instead. On the other hand, when the remaining amount of power of the internal power supply 306 is greater than the first predetermined amount, it is transmitted directly to the base station 200 (step 404).

  According to this, even if the internal power remaining amount of the measuring meter device becomes a predetermined amount or less and a signal cannot be transmitted, it is possible to reliably notify the security center that an intruder has entered the room, thus improving crime prevention. be able to.

  In addition, when there are a plurality of other measurement meter devices provided in a neighboring house, the measurement meter device 300 may be transmitted to a preset measurement meter device, or a plurality of measurement meter devices. You may transmit to the thing with the most internal power remaining amount among them.

  Further, when the control means 302 confirms that the remaining power of the internal power supply 306 has reached a second predetermined amount that is smaller than the first predetermined amount, the control means 302 is directed to the crime prevention device 400 via the communication means 304. A power remaining amount limit signal is transmitted. As a result, the communication means 401 of the security device 400 that has received the remaining power limit signal notifies the indoor resident that the amount of power is low by the alarm means 403. It is possible to take measures such as replacing the power supply.

  The security device 400 normally transmits intrusion alarm information to the security center using a public network, and uses wireless communication to the measurement meter device 300 when connection to the public network is impossible for some reason. The communication mode may be switched so as to transmit the intrusion alarm information. In this case, other controls of the measurement meter device 300 are as described above.

  As described above, in the measurement meter device according to the present invention, when the communication means receives information indicating that the security device has detected an intruder indoors, the communication means detects the intruder into the indoor security device. Since the information indicating that it has been sent to the base station, it is possible to reliably transmit the data to the security center. This is applicable not only to gas meters but also to measuring meter devices that measure flow rates of electricity, water, and others. is there.
