Research On Real-time Online Monitoring Technology Of Slope Surface Runoff And Sand Content

With the development of the times and the improvement of our country’s economic strength,the construction of the expressway is becoming more and more common.The highway has long been the first choice for people to drive.But the collapse of the highway slope and the traffic accidents caused by the collapse are also common.Therefore,it is of great significance to monitor the surface runoff and sediment content in real time on the slope.According to the actual demand of real-time online monitoring system for surface runoff and sediment concentration on expressway slope surface,this paper is divided into three modules,and the whole scheme of the system is designed and implemented.The first module is designed to detect the runoff and sediment content on the slope surface.It is proved by experiments that the data of runoff and sediment content can be accurately detected by the detection device.Second modules:the design of the online real-time transmission system of ZigBee and GPRS,through a simple experiment proved that ZigBee network can be obtained from the testing data protocol conversion through the ZigBee conversion module and then transmitted to the GPRS communication module,and finally detected the income data stored to the monitoring center,to achieve unattended,real-time online monitoring of runoff and sediment data.The third main modules: using the power supply mode of solar energy and battery to solve the problem of energy supply on the spot.Which of these three modules of the monitoring system,to highway slope as the application background,the realization of the network of slope runoff and sediment concentration on-line monitoring and real-time,to prevent highway slope collapse and improve the safety of people highway has important significance and value.
