AUTOMATIC METER-READING RADIO DEVICE, AUTOMATIC METER-READING RADIO SYSTEM, AND PROGRAM THEREFOR

摘要

PROBLEM TO BE SOLVED: To solve a problem that coping with a change is difficult when a peripheral environment such as a building constructed newly and a broken-up building is changed in conventional constitution installed after the priority of a radio slave device is preliminarily determined, and a problem wherein an affected area in the change may come to a large scale to get poor in flexibility, in an automatic meter-reading system using a radio wave. SOLUTION: A random weight time is generated using each timepiece part 205, when the radio slave device 105e and the radio slave device 108e receive a radio data from a base station 102, transceiving processing is carried out recognized as the slave device after receiving a prescribed data packet during the weight times, and the transceiving processing is carried out recognized as a superordinate device hereafter when not receiving the prescribed data packet during the weight times.
