[Abstract]:In today's society, crane is more and more widely used, crane safety monitoring technology has become a hot research topic. Monitoring the crane can let the staff know the running parameters of the crane in real time, and can troubleshoot the crane in time. In this paper, a three-level safety monitoring system for cranes is designed, that is, the field monitoring level, the local monitoring level and the remote monitoring level, so as to meet the needs of the staff at all levels for crane monitoring. The function of crane safety monitor is introduced in detail in the field monitoring level design of crane. It is designed with MC9S12DG128 as the core. The hardware design includes single chip microcomputer minimum system, CAN communication circuit, serial communication circuit, three-phase alternating current detection circuit, gravity sensor signal conditioning circuit, DA output circuit and monitor power supply circuit. The software design includes software design flow, system initialization, three-phase deficiency and phase sequence detection, serial communication program design. In the design of local monitoring level of crane, the process of constructing network and router node by ZigBee coordinator node and adding terminal node to network is analyzed. The application layer of Zstack protocol stack is developed, and wireless data receiving and receiving, serial port application and so on are compiled. The influence of various factors on the transmission distance of ZigBee wireless network is obtained by analyzing the IEEE802.15.4a channel loss model, and the optimization of AODV routing protocol is studied. The monitor interface of upper computer is designed by using graphical programming language LabVIEW, and database Access 2007 is selected for database application and development. In the design of crane remote monitoring level, LabVIEW is used to release the front panel of program on Web for remote workers to view. The embedded Linux remote video surveillance system is designed with ARM development board S3C6410, and the functions of image acquisition, image compression and data transmission are completed based on the design of B / S mode. The communication system based on C / S is designed by using Socekt, so that the remote administrator can control and direct the crane operation. It has been proved that the designed three-stage intelligent safety monitoring system of crane meets the expected performance requirements and has good stability and reliability to meet the requirements of industrial products.
