Application of automation technology in the maintenance of navigation marks in navigation channels

Because water buoy is often wound by floating objects and its performance is affected, the original solution requires a large investment of manpower and resources. This paper designs an early warning system for pressure detection and WiFi communication via chip STM32F407. The system can detect the pressure of the beacon in real time, judge the current status of the beacon, and transmit it to the monitoring system through WiFi communication technology. Pass maintenance information to relevant personnel when pressure exceeds standard value.
