[Abstract]:With the rapid development of global industry, buffer, as a safety protection device, has been widely used in lifting equipment. It can reduce the occurrence of production accidents and ensure the safety of production personnel. The mechanical impact on the buffer with high strength for a long time is easy to cause aging and wear of the buffer and abnormal reset after the bumper is struck. The reset process of manual detection buffer is tedious and inefficient. Therefore, it is of great practical significance to explore the development of an automatic detection and monitoring system instead of manual detection. Aiming at the requirements of crane buffer reset distance detection, this paper designs a buffer detection system based on ZigBee wireless network technology. Through the analysis and comparison of the existing crane buffer fault detection methods, the buffer reset distance is selected as the detection object. And select HC-SR04 ultrasonic ranging sensor module. The DS18B20 temperature sensor module can accurately measure the reset distance after buffer operation in real time. Then the basic principle of wireless sensor network technology is further analyzed. By comparing several popular wireless technologies, ZigBee wireless communication technology with low cost, low power consumption and high transmission quality is selected as the wireless application scheme of this paper. The CC2530 chip of TI company is chosen as the hardware solution of ZigBee wireless communication module. The application circuit of wireless communication module CC2530 and the interface circuit of wireless communication module with host computer and microcontroller are designed. Based on the detailed analysis of the architecture and workflow of the ZigBee protocol stack, this paper designs a set of buffer detection and networking program, and finally realizes the real-time detection and monitoring of the hydraulic buffer of the crane. Finally, the paper summarizes the full text, points out the existing problems of the system, and looks forward to the next research work.
