<P>PROBLEM TO BE SOLVED: To provide a high reliability radio communication system at low cost which permits a radio communication path between a master station and a plurality of slave stations installed in a building to be set easily and also can maintain excellent communication quality even when the radio communication environment changes. <P>SOLUTION: A plurality of slave stations 1 installed in a building 5 are made to transmit at different times of day, and received data of the rest of slave stations 1 and a master station 2 for transmission from each of the slave stations 1 are acquired, and the totalized results of the received data are stored in a reception storage unit 2e1 as a reception condition totalization table 7 which the master station 2 can display in matrix form. The master station 2 selects the standby communication path of each of the slave stations 1 on the basis of the reception condition totalization table 7, so that when the radio communication environment changes and existing communication paths are found to be inappropriate, the standby communication paths are set to new communication paths. <P>COPYRIGHT: (C)2013,JPO&INPIT |
