摘　　要：通过对星型网络结构的无线燃气报警系统的工作原理和设计过程的分析,构建并实现了基于AT89C52单片机、315M无线收发模块以及循环扫描方式的多被测点燃气浓度信号无线监测和报警系统,它能利用中国移动GSM网络实时通知指定用户具体的燃气浓度超标地点,使居民小区、酒店、工厂等场所的多点燃气报警得到了集中化管理。实验结果表明该系统具有低功耗、报警准确、迅速、人机交互性好等优点。The paper describes the working principle and the design process of star-like network structure for wireless gas alarm system, and the wireless monitoring and alarm system of multi-point gas concentration signals based on AT89C52 microcontroller,315M wireless transceiver module and multi-cycle scan mode,is constructed and realized. In such system,China Mobile＇S GSM network is used to immediately notify the designated centration in excess of the specific location, thus the gas alarm system of residential quarters, other places can get the centralized management. Experimental results show that the system has and rapid alarm, as well as good human-computer interaction. user of the gas conhotels, factories and low power, accurate
