In the following description, the distribution devices 2A to 2H are appropriately referred to as the distribution device 2, and the wireless terminals 3A to 3H are appropriately referred to as the wireless terminal 3.

  For example, the distribution devices 2A to 2H are incorporated in electric devices 6A to 6H (hereinafter, appropriately referred to as “electric devices 6”) installed on the ceiling β of the indoor α or attached to the outside. The distribution devices 2A to 2H store, for example, position information of the installation positions where they are installed, and are positioned relative to the wireless terminals 3A to 3H existing in a predetermined radio wave range (that is, an area to be managed) by wireless communication. Information XA to XH (hereinafter referred to as “location information X” as appropriate) is distributed.

  Here, the predetermined radio wave range is determined by, for example, the transmission output from the distribution apparatuses 2A to 2H, the directivity of the antenna, and the like. In the example of FIG. 1, the conical dotted line shown below the distribution apparatus 2A is a distribution line. A predetermined radio wave range in the apparatus 2A is shown.

The position information management system 5 transmits the object information of the management object 7 together with the terminal identification information B of the wireless terminal 3 attached to the management object 7 and the position information X received by the wireless terminal 3. Therefore, it is possible to easily associate these pieces of information. An example of management information managed by the position information management system 5 will be described later.

  Among the wireless terminals 3 shown in FIG. 1, for example, the wireless terminal 3G or the wireless terminal 3H receives a radio signal (for example, time information, orbit information, etc.) from the GPS (Global Positioning System) satellite 9 in the outdoor γ. It is good to calculate the position on the earth.

May be used (for example, Bluetooth (registered trademark)). As a result, it is possible to reduce the number of external I / Fs in the wireless terminal 3-1, thereby reducing the cost of the wireless terminal 3-1.

  As described above, when the wireless terminal 3-1 performs data communication with the management object 7-1 to acquire the object information, the position information management system 5 manages the management object 7 that has been input manually or the like.
