[Abstract]:This subject originates from the project of Science and Technology Application of Jincheng Coal Industry Group, "the Development of Mine main drainage Automation Monitoring system" No. 20100819-2, which is put forward in view of the problems of backward control technology, high failure rate and poor reliability of mine main drainage automation system in our country at present. The underground drainage system is one of the four production systems in coal mine, which is responsible for the important task of removing the underground water gushing, and its normal operation directly affects the safety production of the whole mine. At present, relay control is still adopted in most mines in our country, which is mainly manual control, so the precision of water level detection is not high, the operation is arbitrary, and it is unable to realize the real-time monitoring of water discharge and the scientific dispatch of drainage process. In addition, a few coal mines in China have adopted automatic drainage devices, but their failure rate is high, their reliability is poor, their control function is not perfect, and they can not meet the requirements of unattended automatic drainage. Therefore, the research and development of coal mine unattended automatic drainage system with complete function and high reliability has important practical significance to realize the coal mine production automation. In this paper, the original main drainage system of Sihe Coal Mine is investigated in detail, its working principle is deeply understood and analyzed, relevant materials and documents are consulted at home and abroad, and the overall scheme of mine main drainage monitoring and monitoring system is determined in combination with the requirements of the task book. The secondary control network structure of the upper computer combined with the lower computer is adopted. The upper computer is placed in the ground control room and the lower computer is placed in the underground pump room. Both of them are combined organically to accomplish the task of automatic drainage together. According to the control structure of the system, the hardware circuit of the mine main drainage monitoring and monitoring system is designed, including the signal collection layer, the electronic control box, the operation table and the communication network, and the hardware structure of the ground monitoring center is configured. The rationality and validity of the hardware scheme are verified by laboratory test and field debugging. According to the design requirements of the system and the characteristics of the hardware circuit, the application software of the main drainage monitoring and monitoring system is designed. The application software is divided into two parts: the lower computer software and the upper computer software. The software is based on PLC program and man-machine interface program. It has the functions of data acquisition, real-time monitoring and control, human-computer information interaction, fault alarm and so on. The upper computer software is based on the 6.55 version of Kingview software platform and Microsoft Office Access database. It can store, statistics and analyze the operation data, operation record, fault alarm and so on. And has the function of remote control of underground equipment. The system test platform was set up in the laboratory, and the hardware, software and the whole system were debugged for each unit of the drainage monitoring and monitoring system. Finally, the field industrial application was carried out in 350 central pump room of Donghe well area of Jinmei Group Sihe Coal Mine. The results of system operation show that the system has reasonable structure, high precision of hardware circuit, strong anti-interference, reasonable design of lower computer software, convenient expansion, fast and reliable operation, perfect control function, good man-machine interaction of upper computer software, The picture is simple, the content is rich, the function is complete, the monitoring data is real time accurate, the whole system runs stably, each index has reached the design request, can satisfy the modern coal mine underground drainage demand.
