Abstract


With the improvement of people’s lives and the upgrading of consumption structure, energy demand will change significantly in the structure, but China’s coal-dominated energy structure will not change for quite a long time. As a result, in the field of energy, meeting the demand of national economic for coal is the major task in the current and long-term development.At the present time, foreign coalcutter through the high-voltage circuit and the pilot circuit of main cable, adopted the carrier signal transmission and power line carrier signal transmission of the control core in two ways, coalcutter’s data was sent to the gate road control box, consequently the collaborative work of "triad equipment" was realized. At home, research, design and manufacture institutes involved with coal mine machinery has not been researched and applied about the cooperative control of "triad equipment". Therefore, in order to meet the mining demand of our country’s coal resource and realize less-manned or unmanned mining in working face, this paper requires all information of working face’s triad equipment be transported to gate road. Accordingly monitoring device laid on gate road realized linkage of working face’s triad equipment. All information can be transferred to the dispatching center of ground convenient for controlling and managing.Based on Embedded Systems, this article mainly researched the design of monitoring system and the realization of hardware about coalcutter. On the basis of designing coordinated control system of "triad equipment" and other equipments on working face, it received the transfer function of the system by mathematical modeling design for working face’s coalcutter and scraper conveyer system. Then parameters of PID controller were carried through optimization design by adopting GA. Stated preference analysis using Matlab simulation, application of GA in PID parameter optimization can improve stability and dynamic characteristics of the system. It indicated that the application of GA in PID parameters tuning was feasible and valid. Compared with the method of traditional parameters tuning, GA obviously improved the dynamic characteristics of controller system.The realization of coalcutter monitoring system involved with the transportation of coalcutter’s data to gate road. At present, underground mine’s communication network of national large-scale mines has been extended to gate road. But the communication of the segment from working face to gate road is difficult. The main reason for this is complex environment, dusty, humidity, volatile ups and downs in horizontal and vertical directions, further more, with coalcutter’s continued walking and cutting, all equipments in the working face constantly moved forward in coal and rock. The whole working face in motion. The applications of conventional wired communications, wireless communications and fiber-optic communication in working face has some special difficulties.Based on the actual situation of working face, this paper conducted a wireless communications system. It transported the data of coalcutter to gate road and provided data basis for the realization of control system. In the underground working face of Shenmu Liangshuijing mine, the hardware of this wireless system successfully conducted related trial in our company’s 1620 coalcutter.The design of this monitoring system transported coalcutter data to gate road by using wireless mode. It filled the gap of data transmission at home and abroad. Furthermore, it filled the gap of coalcutter monitoring system’s research.
