Abstract: In order to solve the shortcomings of the traditional meter reading way, this subject proposes a new automatic meter reading (AMR) system。This thesis mainly completed the following several aspects。Firstly,comparing the existing way of meter reading and the short distance wireless communication technology and finally raising a wireless meter reading scheme based on ZigBee technology。But the ZigBee technology should be combined with GPRS technology can realise the remote transmission。In this system, the realization of the ZigBee network communication and GPRS communication is based on CC2530 chips and SIM900A module。The Zigbee network is used to transmit data between wireless gas meter and wireless handsets。The GPRS network is used to realize data transmission between wireless handsets and management center。The focus of this paper is studied data transmission experiment based on the ZigBee network and GPRS network。On the server port ,we can use the online debugging assistant to check the upload data。The characteristics of this system include low cost, low power consumption, ad-hoc network and adaptive and with strong mobility and compatibility。This system can be applied to the wireless meter reading system that terminal equipment is water meters or electric meter。In the Internet industry,it has extensive application prospect 。
