Abstract
The traditional residential gas meter is readed by manual way, which is time consuming , laborious and low efficiency.The traditional manual meter reading can no longer meet the need of people’s lives. Now，business are constantly changing to be automatic.Therefore, the technology of automatic meter reading has become an important topic. This paper is to study the wireless meter reading system, which uses ZigBee technology and GPRS technology , so as to solve the problem of gas meter automatic data collection and transmission.
This article focuses on the following: Firstly, the background and significance of Wireless Meter Reading System, as well as the domestic and foreign development situation of automatic meter reading system. Secondly, it introduces ZigBee technology, including its technical features, protocols, network architecture and so on. In the hardware design of data collection terminal, building tree network based on ZigBee
network protocol on IEEE802.15.4 and ZigBee module selects TI’s CC2530 chip. It also introduces GPRS technology, including its technical
features, protocols, and network architecture. In the hardware design of data transmission terminal, it uses MSP430 MCU and wireless transmission module G24 making telecommunication come true . Finally, it is the design of software. Based on ZigBee protocol stack, data collection terminal uses the application to complete ZigBee network node formation, acquisition and data transmission, which is based on Z-STACK protocol.
