The traditional gas meter reading methods have the disadvantages of hard to come into residence,low efficiency and difficulty to supervise.In order to solve these obstacles,this article proposed one kind of wireless gas meter reading system based on ZigBee technology.This system take PIC18LF4620 and the CC2420 radio frequency receiving and transmitting module as a core,inserts the wireless sensor node to gas meters.With the concentrators in the building and data management center,the automatic gas meter reading system is composed.The practice indicated that ZigBee technology applies in the automatic gas meter reading system,enhanced the system application flexibility,reduced all kinds of problems caused by wiring on-site in gas meter reading system.
