Design of the Poison Gas Detection System with IOP and Surface Acoustic Wave Sensor Array

针对目前日益突出的公共安全和生产安全问题的突发性和不确定性,提出了将声表面波传感器阵列与物联网技术相结合的毒害气体检测系统,并给出了毒害气体检测系统的设计方案,分别从物联网技术和声表面波技术两方面验证了系统的可行性,该系统采用了Zig Bee通信技术和GPS定位手段,利用涂覆不同敏感膜的4通道声表面波传感器阵列及相应的数据处理算法,实现了对H_2S、SO_2等毒害气体的检测和报警,组建了成熟的便于定位的传感器网络,系统经过实验验证达到了预期的设计目标.

In view of the increasingly prominent problem of sudden and uncertainty of the public security and production safety,toxic gas detection system with surface acoustic wave sensor array and Internet of things technology is proposed in this paper. It presents a design scheme of toxic gas detection system,and verifies the feasibility of the system respectively from the Internet of things technology and acoustic surface wave technology. The system realizes gas detection and alarm by using Zig Bee,GPS,and the different sensitive coating film4 channel surface acoustic wave sensor array and the corresponding data processing algorithm and so on. It has formed a mature facilitate localization of sensor network. Through the experiment the system achieves the expected goal.
