为了监测空气环境,针对煤炭不完全燃烧产生的一氧化碳有害气体,提出一种无线传感器网络(WSN)一氧化碳远程监测节点的设计方案。设计了以低功耗片上系统型微处理器C8051F930为控制器,采用金属氧化物半导体在加热条件下和一氧化碳发生氧化还原反应时电阻值随气体浓度变化而变化为检测原理的一氧化碳传感器TGS2442对气体传感信号采集、调理、转换、数据处理,通过支持802.15.4通信协议的无线射频芯片Si4432收发数据,实现了对一氧化碳排放情况的远程监控。
In order to monitor the air environment, aiming at the carbon monoxide harmful gas produced by incomplete combustion of coal, a design scheme of WSN carbon monoxide remote monitoring node is proposed. The low-power chip-based system microprocessor C8051F930 is used as the controller, the metal oxide semiconductor is used under the condition of heating and carbon monoxide redox reaction resistance value changes with the change of gas concentration as a detection principle carbon monoxide sensor TGS2442 on the gas Sensing signal acquisition, conditioning, conversion, data processing, through the 802.15.4 communication protocol support RF transceiver Si4432 transceiver data, to achieve the remote monitoring of carbon monoxide emissions.
