摘要
针对现有的抄表系统的现状与不足,结合燃气表直读技术、无线传感器网络技术和GPRS技术的优点,设计了一套低功耗燃气自动抄表系统。提出系统的整体方案,并对系统的硬件设计、软件设计加以详细说明。该系统由三级网络构成,一级网络和二级网络采用不同的频率,降低了数据传输时的干扰,提高了燃气表智能终端的使用寿命。系统具有结构简单、布置灵活、低功耗等优点。
Aiming at current situation and shortcomings of existing meter reading system, an automatic gas meter reading system with low power was designed based on the advantages of gas meter directly reading technology, WSN technology and GPRS technology. The whole scheme and the hardware and software design are introduced. The system consists of three level network. The first level network and the second level network used different frequency during communication, which decreased the interface of each other during data transmission, and increased the life of the smart gas meter. The system has advantages of easy structure, flexible layout and low power consumption.
