  Next, the operation of this embodiment will be described. The wireless communication system 1 of the present embodiment efficiently establishes a wireless communication path while preventing radio wave interference.

  As shown in FIG. 1, the wireless communication system 1 includes a plurality of wireless communication terminals M1 to M11 arranged at intervals on an indoor ceiling or the like. Now, as shown in FIG. 7, it is assumed that the wireless communication terminals M1 and M2 belong to the group GrA and the wireless communication terminal M3 belongs to the group GrB.

  In FIG. 7, it is assumed that the management apparatus KS has already been turned on and has been turned on all at once for the wireless communication terminals M1 to M3. Each wireless communication terminal M1 to M3 starts transmission of a route request when the power is turned on. Now, as shown in FIG. 8, the wireless communication terminal M1 transmits a route request to the wireless communication terminals M2 and M3 in a short distance by broadcasting (S1). At this time, the wireless communication terminal M1 transmits a data frame route request as shown in FIG. This route request data frame includes a sequence number, a command, a destination, a transmission terminal, and a transmission terminal group (transmission terminal Gr). The sequence number is command specifying information for specifying a command. Since the command is a route request now, the sequence number is route request specifying information. The command is now a route request. Since the destination is the final destination of the command and is now the management device KS, it is the terminal ID of the management device KS as management device specifying information for specifying the management device KS. The transmission terminal is transmission source specifying information for specifying the transmission source of the command. Since the transmission source of the route request is the wireless communication terminal M1, it is the terminal ID of the wireless communication terminal M1. The storage control unit 45 of the wireless communication terminal M1 stores information on these route requests (hereinafter referred to as route request information as appropriate) in the storage unit 47.

  The wireless communication terminal M2 discards the route request (cancel relay transmission) because the group information (group GrA) of the wireless communication terminal M1n that is the transmission source of the route request is the same as the group information (group GrA) of its own terminal. (S2-1). At this time, in the wireless communication terminal M2, the information acquisition unit 43 acquires the sequence number and the route information from the route request, and the radio wave intensity acquisition unit 42 determines the radio wave intensity during communication with the radio communication terminal M1 as the radio wave quality during communication. Get as. The storage control unit 45 temporarily stores the sequence number, route information, and radio wave quality in the storage unit 47. However, when the relay transmission of the route request is stopped, items other than the sequence number may be deleted.

  In the wireless communication terminal M3, since the group information (group GrA) of the wireless communication terminal M1 that is the transmission source of the route request is different from the group information (group GrB) of the own terminal, the communication control unit 44 broadcasts the route request by broadcast. Transmit (S2-2). At this time, in the wireless communication terminal M3, the information acquisition unit 43 acquires the sequence number and the route information from the route request, and the radio wave intensity acquisition unit 42 determines the radio wave intensity at the time of communication with the radio communication terminal M1. Get as. The storage control unit 45 stores the sequence number, route information, and radio wave quality in the storage unit 47.

  Further, the storage control unit 45 of the wireless communication terminal M3 causes the storage unit 47 to store route information like the terminal M3 illustrated in FIG. However, since FIG. 6B shows route information when the wireless communication terminal M3 receives a route request from the wireless communication terminal M2, the destination information of the route information in FIG. “Terminal M2” becomes “terminal M1”.

  Then, the communication control unit 44 of the wireless communication device M3 transmits a data frame route request as shown in FIG. This route request data frame includes the same sequence number, command, destination, transmission terminal, transmission terminal group (transmission terminal Gr) as the route request data frame of FIG. 9A, and also includes the route cost (radio wave quality). It is out. In FIG. 9B, the route request transmission terminal is the wireless communication terminal M2 that is the direct transmission source of the route request. The route cost is the radio wave quality during communication acquired by the radio wave intensity acquisition unit 42, but when the route request is relayed through the plurality of wireless communication terminals M1 to M11, the route cost included in the route request is The radio wave quality is obtained by adding the radio wave quality during communication acquired by the radio wave intensity acquisition unit 42.

  Since the wireless communication terminal M3 transmits the route request by broadcast, the management device KS and the wireless communication terminals M1 and M2 also receive this route request.

  In the management apparatus KS, when the wireless communication unit 51 receives the route request, the radio wave intensity acquisition unit 52 acquires the radio wave quality during communication with the wireless communication terminal M3, and the information acquisition unit 53 determines the sequence number and the route from the route request. Get information and route cost. The route determination unit 54 determines the source of the route request based on the radio quality during communication, the route cost of the route request (radio quality), the source terminal identification information (source ID) of the route information, and the source group information. A wireless route to the wireless communication terminal M1 is determined. That is, the route determining unit 54 adds the radio wave quality during communication and the radio wave quality included in the route request that is the route cost, and calculates the radio wave quality in all transmission routes of the route request. The route determination unit 54 causes the storage control unit 55 to store the calculated radio wave quality in the storage control unit 55 together with the sequence number of the route request, transmission source terminal identification information, and transmission source group information. When the route determination unit 54 receives one route request and stores the information in the storage unit 57, the route determination unit 54 waits for reception of another route request with a sequence number during a preset route request reception waiting time ( S3-1). When the route determination unit 54 receives a plurality of route requests from the transmission source of the route request having the same sequence number (now the wireless communication terminal M1) received during the route request reception waiting time, The relay route of the route request with the best radio wave quality (route cost) is determined as the wireless route (S4).

  In addition, the wireless communication terminals M1 and M2 that have received the route request from the wireless communication terminal M3 have the communication control unit 44 that the group information of the source wireless communication terminal of the route request, the group information of the own terminal, and the past Based on the route request, the relay transmission of the route request is controlled. That is, the communication control unit 44 of the wireless communication terminal M2 transmits a route request having the same sequence number as the route request for which relay transmission is stopped (discarded) to a wireless communication terminal that is a wireless communication terminal having group information different from the group information of the own terminal. When received from M3, the relay transmission of the route request by the wireless communication unit 41 is stopped (S3-2).
