[Abstract]:With the rapid development of the coal industry in China, the belt conveyor, as the main transportation equipment in the coal mine surface and underground, plays an important role in the coal mine transportation work, but the accidents caused by it are also one of the factors that hinder the development of the coal mine. The safe and stable operation of belt conveyor is directly related to the efficient production of coal mine. Mine belt conveyor protection and fault diagnosis system is an important part of coal mine safety monitoring system, and its research is of great significance. This paper analyzes and summarizes the research status of belt conveyor protection and fault diagnosis system at home and abroad, as well as the structure, fault mechanism and characteristics of belt conveyor, aiming at the key technology of belt conveyor protection and fault diagnosis. Firstly, the safety protection and technical index of belt conveyor, the network communication interface technology of security monitoring and the software platform of upper computer are studied deeply. In addition, the signal processing analysis and fault diagnosis technology are fully studied. The overall scheme of mine belt conveyor protection and fault diagnosis system is put forward. The protection and fault diagnosis system of mine belt conveyor is designed, including the data acquisition of field monitoring station, the design of data communication interface and monitoring software of upper computer. First, the S3C2440 controller communicates with the main controller of the belt conveyor through RS-485 bus, and communicates with several vibration acquisition nodes through Smart Node wireless module to realize the comprehensive protection of the belt conveyor. Secondly, the S3C2440 controller uses Ethernet to transmit the monitoring data to the general monitoring station based on Modbus / TCP protocol. Finally, the software monitoring platform is designed. Through empirical mode decomposition (EMD) and genetic error back-propagation (GA-BPN) neural network model, fault identification of belt conveyor used in mine is carried out. The functions of displaying, storing, analyzing, alarming and managing the running state information of belt conveyor are realized. The test results are consistent with the theoretical analysis and reach the design goal. The belt conveyor protection and fault diagnosis system designed in this paper can effectively monitor the fault of belt conveyor, such as deviation, tearing, stacking, smoke temperature, skid and so on. The requirements of stable information transmission and high fault identification rate solve the problems of protection and fault diagnosis of belt conveyor used in mine and promote the safe production of coal mine. It has certain engineering application and theoretical research value.
