摘要
工业水箱中的污水在排放前进行液位与PH值检测对生态环境保护具有重要意义。本文设计一种以STC12C5A60S2单片机为控制器的小型污水水情测控装置。采用HS-SR04传感器检测污水水箱液位,E-201-C传感器检测污水PH值,测得的电压信号经由AD7705完成信号转换,将水箱液位、PH值和供电电压送至单片机处理,由LCD12864显示。在Visual Basic 6.0平台开发上位机管理系统,通过AS13-TTL无线串口通信将下位机采集的水情信息传输到管理系统进行实时监控。试验结果表明,系统具有响应速度快,测量精确的优点。
The detection of liquid level and pH value of sewage in industrial water tanks before discharge is of great significance to ecological environment protection. This paper designs a small sewage water condition measurement and control device based on STC12 C5 A60 S2 microcontroller.The HS-SR04 sensor is used to detect the liquid level of the sewage tank. The E-201-C sensor detects the PH value of the sewage. The measured voltage signal is converted by the AD7705. The liquid level, PH value and power supply voltage are sent to the MCU for processing,displaying by LCD12864.In the Visual Basic 6.0 platform, the upper computer management system was developed. The water information collected by sensor is transmitted to the management system for real-time monitoring through AS13-TTL wireless serial communication. The test results show that the system has the advantages of fast response and accurate measurement.
