[Abstract]:With the global resource supply and environmental pressure outstanding, in the coal industry transformation process, the production links more use of automation input and application is essential. Aiming at the practical application of fully mechanized coal mining automation technology in 7 meters mining face, this paper analyzes the present situation of the development of fully mechanized mining complete sets of technology and equipment, and puts forward the idea of applying distributed control system to fully mechanized coal mining face. The automatic application and data acquisition of hydraulic support and pump station are designed separately. The data are collected by each sub-station, and the monitoring and control are unified, and the underground working face production information is transmitted to the ground monitoring main station in real time through the mining industry Ethernet. The integration of downhole information is realized. The paper analyzes the advantages and disadvantages of the old communication control system and the new communication control system of the shearer, selects the hardware for the control and data acquisition of the shearer, and expounds the overall logic relation of the communication control system of the shearer. This paper analyzes the automatic cutting logic of 7 m shearer in detail and gives the compensation scheme of drum height. Aiming at the hydraulic support, the principle of communication between the terminal station of the support and the centralized control station is simply introduced, and the practical application scheme for the monitoring data of the support is put forward, and the optimization flow scheme of the automatic operation process is put forward to save the production time. Improve production efficiency. In the last chapter, the program and configuration design of the data acquisition and control system are introduced and applied. The research conclusions are of great significance and reference value for the rational design of the control system of fully mechanized coal mining face and other equipment, improving the working performance of the equipment and increasing the production efficiency.
