Research on water security using ultrasound and Internet of Things cloud computing technology

面对日益严峻的用水安全挑战,寻求高效、精准的监测与管理手段尤为重要。针对非正常用水情况不易及时发现而造成损失的问题,开发了融合应用超声测流量与物联网云计算技术的用水安全系统。进行系统方案设计,通过对比分析,选择U型超声测流量方法;然后建立用水模型,开展正常用水与非正常用水的对比研究,得到爆管、渗漏和异常用水等情况的水流量特点,并根据三种非正常用水情况的特点,设计一套按照用水统计情况设定参数的判定算法;最后,搭建测试环境并开发测试程序,进行系统各功能测试。结果表明:按照设定的参数,所提系统可准确判定爆管、渗漏和异常用水等情况,并能及时关阀。经过适应性开发后,该系统可进一步推广至工厂、商场和写字楼等场景。

In the face of increasingly serious water security challenges,it is particularly important to find efficient and accurate monitoring and management tools.In allusion to the problem that abnormal water usage is not easy to be detected in time and cause losses,a water security system integrating the ultrasonic flow measurement and Internet of Things(IoT)cloud computing technology is developed.The system scheme is designed,and the U-shaped ultrasonic flow measurement method is selected by the comparative analysis.A water usage model is established,and a comparative study is carried out between normal water usage and abnormal water usage to obtain the characteristics of water flow under the conditions of pipe burst,leakage and abnormal water usage.According to the characteristics of three kinds of abnormal water usage,a set of determination algorithm based on water usage statistics is designed.The testing environment is set and the testing program is developed to test the system functions.The results show that the proposed system can accurately determine the situation of pipe burst,leakage and abnormal water usage according to the set parameters,and can close the valve in time.After adaptive development,the system can be further extended to scenarios such as factories,shopping malls and office buildings.
