摘要
为了提高水质监测系统中pH值的采样精度,并解决定时定点采集数据耗费人力物力问题,设计并实现一种基于物联网的水质监测系统。首先,为了提高pH值的测量精度,硬件电路上使用AD8603进行前级调理,AD7792进行高精采样,软件设计上采用中值滤波和滑动滤波算法。其次,搭建水质监测服务平台,监测数据通过ZigBee传输到主机,在经由GPRS发送到服务器,用户使用手机APP或Web可以远程监控每台设备的数据。结果表明,所提方法提高了监测设备的pH值测量精度,监控平台运行稳定可靠。
In order to improve the pH value sampling accuracy of water quality monitoring system and solve the problem of consuming manpower and material resources while collecting data at fixed time and fixed point,a water quality monitoring system based on Internet of Things is designed and implemented. The AD8603 is used in the hardware circuit for pre-conditioning and the AD7792 for high-precision sampling to improve the measurement accuracy of pH value. The median filtering and slip filtering algorithm algorithms are used in the software design. The water quality monitoring service platform is constructed. The monitoring data is transmitted to the host through ZigBee and then sent to the server via GPRS. Users can remotely monitor the data of each device with the mobile APP or Web. The results show that the water quality monitoring system can improve pH measurement accuracy of the monitoring equipment and make the monitoring platform running stable and reliable.
