Automatic Monitoring System Of Culvert Water Based On STM32F103 Design And Implementation

With the number of private cars increased year by year,in order to slow down the traffic pressure,the major cities have established a huge number of culverts,overpass and so on.And the rainy weather will lead to paralysis of the drainage system,so that a large number of stagnant water in the low-lying areas of culverts,tunnels and other tunnels can not be discharged in time,which poses a great threat to people's lives and property.Therefore,it is urgent to establish a perfect automatic monitoring system for culvert water.This paper is aimed at the phenomenon of a large amount of water accumulation in the lower part of the road,such as the tunnel,the tunnel,and so on.It designs and realizes a culvert water automatic monitoring system based on STM32F103.The system is mainly composed of a machine of monitoring terminal and PC monitoring center.First of all,the system collects the water level information of water by ultrasonic sensor,Then in the monitoring site using LCD display real-time display of water information and give the corresponding warning;According to the working principle of the blocker,the system adopts the method of controlling the angular displacement of the stepping motor to realize the landing function of the blocker.The GPRS wireless communication module is used to send the collected water level information to the monitoring and control center,At the same time,the collected water level data information is sent to the relevant personnel in charge of the water treatment through the GSM network by the way of short message.After receiving the data transmitted by the GPRS,the data center is displayed in the digital and the curve form in the man-machine interface which is designed by C#.Finally,the received data is stored in the SQL database.Monitoring and control center can also be through radio,television,web site,release culvert water level information.After the whole simulation test,the man-machine interface can display the data accurately,and has the characteristics of low bit error rate and strong stability;Stepper motor can work automatically according to the height of water level,greatly reduces the cost of the system.In addition,the system can effectively remind people about the culvert water information,prevent people from low areas into water deep culvert or road.For people's travel security,provides the guarantee.
