[Abstract]:Based on the analysis and research of electro-hydraulic control system of hydraulic support in fully mechanized coal mining face, this paper makes a deep research on the flameproof and intrinsically safe centralized control computer. The research content is "the development of electro-hydraulic control system of hydraulic support in unattended working face" (item No.: 0S2013ZR0493) and the important special project of Shanxi Province, "Full-automatic unattended fully mechanized mining workers", which is a special project of international scientific and technological cooperation and exchange. Research and Development of facet Technical equipment "(Project No.: 20111101024) is an important component." At present, the demand for automation of hydraulic support in fully mechanized coal mining face is increasing day by day. The remote automatic control of electro-hydraulic control system of hydraulic support in coal face has become one of the key technologies of working face automation. The flameproof and intrinsically safe centralized control computer is the main device for realizing the automation of the electro-hydraulic control system of the hydraulic support. With the cooperation of the terminal controller, the interframe controller and the ground monitoring center, the real-time monitoring and automatic control of the hydraulic support are realized together. Centralized control, local control, controller program online upgrade and other functions, the final automation of fully mechanized mining face. In recent years, electrohydraulic control technology has developed rapidly in foreign countries, and has been more and more widely used in practical production. However, the centralized control computer of hydraulic support electrohydraulic control system in China basically depends on import, long supply period, high price and difficult maintenance, which greatly restricts the development of coal mine industry automation in our country. Therefore, it is of great significance to study the flameproof and intrinsically safe centralized computer with independent intellectual property rights. By studying the control strategy of electro-hydraulic control system of hydraulic support in automatic working face, this paper determines the centralized control scheme of electro-hydraulic control system, designs the hardware of flameproof and intrinsically safe centralized control computer, and develops the software of centralized control system. The main research contents are as follows: by consulting a large number of relevant documents and investigating the application of electro-hydraulic control system in fully mechanized mining face at present, The functional requirements and technical specifications of electro-hydraulic control system of hydraulic support are determined. The control scheme of central control system of hydraulic support is designed, and the functional requirements of flameproof and intrinsically safe centralized control computer are put forward. The overall structure of the hardware circuit of the centralized control computer is determined, and the selection of the control module and the design of the intrinsically safe isolated communication circuit are completed. In order to adapt to the bad environment of underground, anti-interference measures are taken to the communication circuit, and the flameproof shell is designed. The centralized control program is developed with embedded SQL based on PowerBuilder, which mainly includes RS-485 communication subprogram of TCP / IP communication subprogram, on-line upgrade of software, and so on, which can realize real-time monitoring of working face running state. Centralized control of hydraulic support electro-hydraulic control system and management function of database. The test bench of hydraulic support electro-hydraulic control system was built in the laboratory, and the functions of centralized control computer were debugged in the laboratory. After assembling the product, the ground trial operation and underground industrial operation were carried out in Jin Coal Group. The results of debugging and running show that the structure of the flameproof and intrinsically safe centralized control computer is scientific and reasonable, and the state signal of the hydraulic support can be obtained quickly and accurately, and the real-time and effective control of the hydraulic support can be carried out. The on-line program upgrade of the terminal controller and interframe controller of hydraulic support is realized, which lays the foundation for automation of fully mechanized mining face.
