摘要
针对养殖场周围空气污染问题,根据三电极电化学气体传感器的工作原理,设计了养殖场空气污染监测系统。该系统选用嵌入式LPC2148芯片作为终端控制器,VC++6.0创建上位机监控界面,使用串口通信控件MSComm和终端进行通信,并用MSChart图表控件绘制了NH3和H2S气体浓度曲线。为此,详细地介绍了系统终端与上位机界面的设计和原理。实验证明,该系统能准确、灵敏地检测出有毒气体的浓度,在养殖场周围环境保护上具有很好的应用价值。
Aim at resolving the air pollution around farms,and according to the work principle of the three-electrode electrochemical gas sensor,this paper design a farm air pollution monitoring system.The system selects embedded chip LPC2148 as a terminal controller,creates PC monitor screen with VC++6.0,uses serial communication control MSComm to communicate with terminal,and draws NH3,H2S gas concentration curve by using MSChart chart control.This article not only describes the design and principles of the system terminal and the host computer interface,but also proves that this system can detect the toxic gases' concentration sensitively and accurately.So It has good application value in the environmental protection around farms.
