Dynamic Monitoring System of Sewage Treatment Process Based on Internet of Things

摘要:

针对污水处理过程复杂、区域广、监测点多、现场布线困难等特性,以CC2530为核心设计了无线传感器节点和汇聚节点,实现对污水处理过程中的设备状态、污水的进出口流量、PH值、COD等监测因子的实时采集,以Zigbee技术实现各无线传感器节点之间的数据传输,以GPRS技术实现汇聚节点与多平台对接；为确保监控系统所接信号不影响原控制系统的正常运行,特设计了高精度电流扩展模块、串口扩展模块等；经现场长时间运行表明,系统有很好的灵活性和扩展性,运行稳定可靠,通过对污水处理过程各参数的动态分析,为提高污水处理效率和节能环保起到重要作用。

Abstract:

For sewage treatment process is complex, wide area, more monitoring point, site wiring difficulty and so on, used CC2530 as the core to design wireless sensor nodes, aggregation nodes, realized real-time acquisition of device status、sewage flow、PH value、COD and other monitoring factors of import and export in the sewage treatment process,realized data transmission between the sensor nodes using the Zigbee wireless technologies,realized docking between gather nodes and platforms using GPRS. To ensure that the signals of monitoring system connected does not affect the normal operation of the control system, designed the high precision current extension module, serial port extension module etc. In the long running shows this system exhibits good flexibility and scalability, stable and reliable running, through the dynamic analysis of various parameters in the sewage treatment process play an important role in improving the efficiency of wastewater treatment and environmental protection.
