Japanese Patent Laid-Open No. 7-006283

  By the way, in the wireless device system including the wireless master device and the wireless slave device as described above, since the wireless master device and the wireless slave device can transmit and receive information by wireless communication, it is imposed when the wireless slave device is installed. As a result, the number of restrictions imposed is reduced, and it can be installed freely in appropriate locations.

  Therefore, in a gas meter reading system using radio, a plurality of wireless slave units are installed in one master unit, a plurality of meter meter readings are performed, and meter reading information is reported to the center via the master unit via a public line. The form of communication has increased.

  In addition, with the recent increase in crime prevention and disaster prevention awareness, there has been an idea that the system configuration of fire alarms and security devices, etc., should only have alarms installed only at priority and warning locations. We have come to want to achieve strict crime prevention and disaster prevention by installing wireless devices in various places and linking each device wirelessly.

  With this trend, when an increase in the number of wireless slave units that can be connected to a single master unit is required, the conventional ID registration method requires a large number of wireless slave units to be registered. You will have to spend a lot of time and effort. Further, since the number of devices constituting the wireless device system tends to increase in the entire system, improvement in workability during installation and increase in efficiency are desired.

  In view of such a situation, the present invention does not increase the burden of registration of a wireless master unit even if the number of devices of the wireless device system is increased, and is intended to improve workability and efficiency during installation. An apparatus system is provided.

  In order to solve the above-described conventional problems, the wireless device system of the present invention is configured such that when initial setting with a wireless parent device is started via the parent-child initial setting unit, an identification number (ID ) Is transmitted to the wireless master device, and when the initial setting with the wireless grandchild device is started via the descendant initial setting means, the wireless slave device uses the wireless grandchild device with an identification number (ID) preset in the wireless grandchild device. Is to be received from.

  According to this, it is not necessary to perform initial setting work between the wireless master unit and all the wireless devices, the wireless master device initializes only the wireless slave device, and the wireless slave device initializes only the wireless grandchild device. As a result, the number of devices constituting the wireless device system as a whole system can be increased.

  In the wireless device system of the present invention, when the number of devices constituting the wireless device system is increased, a system configuration is formed by a combination of a wireless master device, a wireless slave device, and a wireless grandchild device, and the wireless master device includes only a wireless slave device. By registering only the wireless grandchild device in the wireless slave device, it is possible to share the wireless slave device without increasing the memory load required for registration of the wireless master device. Therefore, the wireless master device can be configured with the same memory capacity as the wireless slave device.

  Also, it is only necessary to register the wireless master device only with the wireless slave device and the wireless slave device with only the wireless grandchild device, and the wireless master device is not installed at a reachable range capable of communicating with all the wireless devices constituting the wireless device system. Therefore, it is possible to make it difficult to receive restrictions on the installation location of the wireless master device.

The first invention is a wireless device system comprising a wireless master device, a wireless slave device communicating with the wireless master device, and a wireless grandchild device communicating with the wireless slave device. The wireless slave unit includes a parent-child initial setting unit for starting the initial setting and an initial setting unit between the descendant for starting the initial setting with the wireless grandchild device, and the wireless slave unit is connected to the wireless parent device via the parent-child initial setting unit. When the initial setting with the wireless device is started, an identification number (ID) preset in the wireless master device is received from the wireless master device, and the initial setting with the wireless grand device is started through the inter-descendant initial setting means. And the identification number (ID) received from the parent device is transmitted to the wireless grandchild device, and the identification number (ID) preset in the wireless parent device is stored in the identification number storage means of the wireless child device. is there.

  According to this, since the identification number (ID) of the wireless master device can be transmitted to all the wireless slave devices and the wireless grandchild devices, the identification number (ID) of the wireless master device is set as an ID common to the entire wireless system. By using this ID for wireless communication, it is possible to broadcast all over the wireless system composed of the wireless master device, wireless slave device, and wireless grandchild device. Communication time can be shortened and efficient communication is possible.

According to a second aspect of the invention, in particular, in the first aspect of the invention, when the wireless slave device starts initial setting with the wireless master device via the parent-child initial setting means, the communication condition preset in the wireless master device is wirelessly transmitted. When the initial setting with the wireless grandchild device is started via the descendant initial setting means, the wireless slave device transmits the communication condition received from the wireless master device to the wireless grandchild device.

  According to this, since the communication conditions between the parent and the child and the communication conditions between the descendants can be made the same, the communication conditions such as the channel to be used and the transmission / reception time are configured by the wireless master device, the wireless slave device, and the wireless grandchild device. If the communication conditions of the wireless master unit are set so that they do not interfere with other wireless systems, the wireless slave unit and the wireless grandchild device will not interfere with other wireless systems. Can be.

The third invention, in particular, in the first or second invention, the wireless master unit includes a parent-child initial setting means for starting the initial setting means with the wireless slave device again when the initial setting with the wireless slave device is completed, The wireless slave device includes descendant initial setting means for activating the initial setting means with the wireless grandchild device again when the initial setting with the wireless grandchild device is completed.

  According to this, once the initial setting of the wireless slave unit is activated in the wireless master unit, the wireless master unit continuously performs the initial setting with the slave unit without the second activation of the wireless master unit. Once the initial setting of the wireless slave unit is started with the wireless grandchild device, the wireless slave device is continuously initialized with the wireless grandchild device even if the wireless slave device is not activated for the second time. This makes it possible to shorten the time until the initial setting of the entire wireless system is completed and the communication time, thereby enabling efficient initial setting.

According to a fourth aspect of the present invention, in particular, in the first to third aspects, when a push button is provided as an activation means of the parent-child initial setting means and the descendant initial setting means, and the push button is pressed for a shorter period of time,
The wireless slave device transmits an identification number (ID) preset to the wireless slave device to the wireless master device, and when the push button is pressed longer than the predetermined period, the wireless slave device is preset to the wireless grandchild device. An identification number (ID) is received from a wireless grandchild machine.

  According to this, when the push button is pressed shorter than the predetermined period, the wireless slave device changes the communication procedure so that it starts from wireless transmission, and when the push button is pressed longer than the predetermined period, it starts from reception. Thus, the initial setting can be performed with both the wireless master device and the wireless grandchild device with one push button.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.
