The project has been developed ZDYZ-JK type hydraulic support controller based on C8051F020 mcu. The industrial test in Gushuyuan Coal Mine of JAMG has been carried out from July 2013.In the process of industrial test, there are still a lack of system function and a poor product perance and stability. With the further development of technology, the domestic electric hydraulic control technology level has been continuously improved, the function has been improved, and the automatic control requirement of the hydraulic support of the coal mine automation production is continuously improved. In view of the above problems,, the project team has developed electric hydraulic control system based on 16 single chip microcomputer, the overall design scheme of the hydraulic support controller has been determined, and the hardware and software of the system has been developed. Compared with the domestic and foreign advanced systems, combined with the actual underground working situation of the last generation controller ,the existing design program still has some defects. So the research content of this paper is to advance the design and perfect the relevant functions based on the design of the existing second generation controller. In addition, the research content of this paper is to carry out the research of the hydraulic support emulsion high pressure anti filter station controller including develop its overall design program and its hardware and software ,which meeting the the actual needs of the project.The main research contents of this paper are as follows 1.Referring to the domestic and foreign advanced bracket system, 万方数据 太原理工大学硕士研究生学位论文 IV combining underground operation experience in the first generation of controller, the improved design scheme is design by summarizing and analyzing the hardware circuit design, software process design and function setting of existing second generation stent controller design scheme. 2.The drive circuit of the solenoid valve has been designed to improve the reliability of the controller. The EMC design of the power circuit and the communication circuit has been carried out to improve the anti-interference perance of the controller. The hydraulic support posture adjustment procedures, hydraulic support two-way sorting procedures, hydraulic support control warning procedures, hydraulic support anti filter, hydraulic support fault diagnosis procedures has been edited to expand the function of the hydraulic support controller and enhance the practicality of the controller. The test of improved hydraulic support controller has been put into practice to verify the design scheme and test the stability of the program in the test plat. 3. The overall plan of emulsion high pressure back ing filtering station controller has been drew up. Through analyzing the control demand of high pressure filter, the hardware structure of the controller of the filter station is determined, and the control mode and the function of the controller are established. 4. The hydraulic support emulsion high-pressure backwash filter station controller has been developed, and the three modes of controller operation automatic control, semi-automatic control and manual control has been put forward, including controller hardware circuit, the control program of three modes, the program of sensor fault, filter fault diagnosis and the parameters setting procedures. Through the laboratory test, the operation of the various functions has been examined. The research of controller has achieved automation of the emulsion high pressure back ing filter station is realized, which improves the systems automation degree and system reliability.
