Description

  The present invention relates to a wireless system for automatic notification that wirelessly transmits information collected by a meter or a security sensor from a wireless slave unit to a wireless master unit, and in particular, information for specifying a communication partner to the wireless slave unit and the wireless master unit. It relates to technology for registration.

  2. Description of the Related Art An automatic meter reading system is known that collects meter reading data of a meter that measures the usage amount of electricity, gas, water and the like by a host device such as a center device via a communication line such as a telephone line. There is also known a disaster prevention system for reporting information such as alarms collected by a security sensor such as a fire sensor or a human sensor to a host device via a communication line.

  In a wireless system for automatic notification such as an automatic meter reading system or a disaster prevention system, a meter or a security sensor and a communication line are separated from each other and it is often difficult to connect them by wiring.

  Therefore, the wireless slave unit is connected to the meter or security sensor, the wireless master unit is connected to the communication line via the network control device, and wiring is performed by performing wireless communication between the wireless slave unit and the wireless master unit. A technique that is unnecessary is proposed (for example, Patent Document 1).

In order to perform wireless communication between the wireless slave unit and the wireless master unit, information necessary for wireless communication, such as the ID of the communication partner between the wireless slave unit and the wireless master unit, is specified in advance in order to identify the communication partner. Initial registration to register is required. Conventionally, this initial registration starts the initial registration operation by an operation such as inputting an initial registration activation switch of the wireless slave unit and the wireless master unit, and then wirelessly by wireless communication in the same manner as the wireless communication during the subsequent operation. Information such as the ID of the communication partner is registered between the slave unit and the wireless master unit.

The surface 50a of the housing 50 and the surface 60a of the housing 60 are brought close to each other so that non-contact communication is possible with the magnet 59b of the machine 5-1 facing each other. In this way, the reed switch 57b is operated by the magnet 69b and a signal to start the initial registration is output to the control unit 53, and the reed switch 67b is operated by the magnet 59b and the initial registration is performed in the control unit 63. Outputs a signal to start. When the control units 53 and 63 detect signals from the reed switches 57b and 67b, respectively, the non-contact communication unit 58 and the non-contact communication unit 59 become communicable and start initial registration.

Next, the operation at the time of initial registration of the automatic notification wireless system 4-1 according to the second embodiment of the present invention will be described in detail with reference to the flowcharts shown in FIGS.
