ASYNCHRONOUS COMMAND ACHIEVING METHOD OF REMOTE METER READING SYSTEM

摘要

PURPOSE: An asynchronous command executing method of a remote meter reading system is provided to perform a communication efficiently with a zigbee node which is in active mode during a predetermined time. CONSTITUTION: A concentrator(20) receives a command signal request from a meter server(40)(S10). The concentrator receives an active notification signal from a zigbee node(10)(S20). The concentrator transfers the command to the zigbee node by the priority order(S40). The concentrator receives the command execution result according to the command signal from the zigbee node. The concentrator transfers the command execution result to the meter server(S50).
