So that ZigBee technology with above advantages provides a better choice for automatic meter reading system’s development. To adopt ZigBee wireless network protocol, using free frequency band to communicate, collaborative testing user’s electro-situation, dynamic networking and communication of automatic routing become hotspots for research in field of automatic reading meter system. This paper includes the specific as follows: First, introduce topic background, discussing research status from domestic and abroad, and summarized describes the main characteristics and ZigBee technical specifications. Secondly, ZigBee protocol stack research from shallow and deep ZigBee physical layer, detailed instructions for MAC layer, network layer and application layer function, ZigBee protocol stack of the analysis is the foundation behind the software design. Then, shows the theory of construction of the wireless meter-reading, and building the wireless network and transferring date etc, and designing that from the hardware design and the software the realization of wireles
