ZigBee technology is an emerging short-range, low-power, low-cost wireless communication technology. It is mainly based on the IEEE 802.15.4 wireless standard, and coordination to achieve communication between thousands of tiny sensors. ZigBee technology in the field of smart home, building automation, industrial control, medical testing its protocol is simple, low cost, feature-rich, easy networking, has a broad market space. Compare, ZigBee wireless meter reading technology with traditional manual meter reading, IC card prepaid table, the cable meter reading as well as the advantages and disadvantages of wireless meter reading, with its state-of-the-art technology, easy to implement, high reliability, low cost, easy to spread, etc. to become one of the trends of the future development of wireless meter reading system. Wireless meter reading system is very high requirements on system power consumption and anti-jamming, the selection has a low power consumption, high noise immunity ZigBee wireless sensor network technology, the establishment of a residential area wireless meter reading network model, the network model of communication, energy consumption initiate the relevant study. The main work of this paper is as follows: (1) existing wireless meter reading network power consumption the poor reliability problem, we take into account the actual application environment of the residents of the community, in reference to the star tree ZigBee network The topology of the network model, a new type Star - tree network model, which uses the star and tree network model combined to build a new network model. Through the analysis of the function of each device in the network model and working principle, the paper proposes the specific design of the network layer, and meter reading network between the devices work processes and data transmission elaborated. (2) In order to reduce the amount of redundant information in the meter reading network, improve the success rate of the network traffic with the correct rate, the overall design of the wireless meter reading system, build ZigBee wireless meter reading development platform and the platform of the new the formation of star - a tree network communication, anti-interference and energy consumption testing. Experimental results show that: albeit verified in the laboratory, but in the short distance range to ensure high communication success rate and the correct rate is guaranteed. (3) In order to reduce the energy consumption of the meter reading node, in the process of building a ZigBee wireless meter reading development platform for ZigBee wireless meter reading system, the Atmega88 low-power microcontroller and CC1100 wireless transceiver module designed a new type of meter reading terminals node. The research areas of research of ZigBee technology in the wireless meter reading, lay the foundation to reduce the development costs of wireless meter reading system, but also for ZigBee technology research and development in other areas to provide a reference.
