RADIO SYSTEM FOR AUTOMATIC METERING

摘要

PURPOSE:To eliminate interference from other system by setting a communication channel for radio communication and a communication time for synchronization matching with a clock circuit. CONSTITUTION:A clock circuit 17 is a circuit to implement time management of a radio equipment and a time synchronization matching communication time and communication channel setting circuit 18 is a circuit to set a time synchronization matching communication time and a communication channel for time synchronization matching communication. Then the communication channel and the time synchronization matching communication time in the radio communication between a master radio equipment 27 and a slave radio equipment 28 are distributed to avoid interference with radio communication of other systems by using a call code. That is, when the communication time as the time synchronization matching communication time is distributed to 24 hours (each due time), for example, '' a remainder when a numeral of a call code (12 digits) is divided by 24'' is set for the communication time, then the time synchronization matching communication time is set at random for each radio equipment.
