摘　　要：为便于对河道水质实现自动、实时在线监测,设计一款较为隐蔽的基于NB-IoT的漂浮式污水监控器。采用STC15F2K60S2为微控制单元(MCU)对水体的温度等参数进行采集,通过NB-IoT通信模块对采集的数据进行实时传输,利用人工神经网络建立水质预测模型,并使用C#和微信小程序分别开发电脑端、手机端监控程序。通过自主研发的终端进行相应实验数据的采集,再使用MATLAB数学软件对实验数据进行分析和拟合,结果表明,漂浮式污水监控器中各类传感器性能符合要求,且轻便、智能,PC端与手机端程序运行良好,实时性、精度等性能均满足实际生产生活要求。In order to realize automatic and real-time online monitoring of river water quality,the article designs a relatively concealed floating sewage monitor based on NB-IoT.It uses STC15F2K60S2 as micro control unit(MCU)to collect the water temperature and other parameters,transmits the collected data in real time through NBIoT communication module,establishes the water quality prediction model by using artificial neural network,and develops the monitoring program of computer and mobile phone by using C#and WeChat program.It collects the corresponding experimental data by the self-developed terminal,and then uses MATLAB mathematical software to analyze and fit the experimental data.The results show that the performance of all kinds of sensors in the floating sewage monitor meets the requirements.It is light and intelligent,the programs of PC end and mobile phone end run well.And the real-time performance and accuracy meet the actual production and living requirements.
