污染气体排放监测节点的设计与实现
|
摘要
文中选用MAX14830芯片为EFM32单片机扩展出4个串口,分别接串口输出的智能化气体传感器,同时单片机内部的A/D转换器通过预留的接口可直接外接模拟输出的气体传感器,使系统具备同时监测排放气体中多种不同类型有害气体浓度的能力;测量结果可以在单片机的液晶触摸屏上直接显示,也可以经单片机外挂的通信芯片SIM808通过商用通信网络传输到指定目的地;以此模块作为网络节点安装于需监测的生产线或排放口上合适位置,可以方便地建立起工业企业污染气体排放的监测系统。
In this paper,chip MAX14830 is chosen for single-chip microcomputer EFM32 extending four serial ports,which respectively connects intelligent gas sensor with serial port output. At the same time,the integrated A/D convertor directly connect via reserved port to outer gas sensor with analog output,which enables the performance of monitoring concentration of different types of exhausted harmful gases. The results of measurement can show on LCD touchscreen,or transmit to target place by use of SCM hanging communicate chip SIM808 via commercial communication network. Installing this module as a network node on proper location of discharge outlet or in need of monitoring produce line,which conveniently form up industrial entrepreneur pollution gas emission Monitoring system.
