Design of Data Acquisition and Monitoring System for Tower Crane Based on STM32
A tower crane data acquisition and monitoring system based on STM32 was designed to meet the real-time monito-ring requirements of operating state parameters and operating environment for tower crane operations.The system used STM32F103RCT6 as the core microprocessor to collect and process the data of various tower crane operating state parameters combined with sensors.The sensor signals were transmitted to the microprocessor through the A/D conversion module with digital isolation and the RS485 to TTL module.Then the microprocessor sent the collected sensor data to the local area network formed by industrial switches and network cameras through the serial port to Ethernet module.Finally,the upper computer page of the system was developed by using the Java language combined with the Spring Boot framework to display the sensor data and video monitoring screen.Through the test,the system can monitor the operating status parameters of the tower crane and the operating environment of the tower crane in real time.The average relative error of the data collected by the sensor is 0.74%,and the aver-age delay of the camera monitoring screen is 20.4 ms,realizing high-speed and accurate real-time monitoring of data.It meets the system requirements for monitoring tower cranes.
