Research On The Control System Of Hydraulic Support Test-bed

As the key support equipment of the coal mine fully mechanized working face, Hydraulicsupport has become an important part of coal mine production safety. But because thecorresponding detection device is not perfect, the development of new products and marketsare hindered. Therefore, in order to improve the detection quality of hydraulic support, theresearch and development of new control of Hydraulic Support Test-bed System is imperative.Through the analysis of the MT312-2000test standards and the demand of user to thesystem, in accordance with safety, real-time, stability and reliability requirements, systemdesign, create a set of effective system control scheme. This paper develops a measure andcontrol of hydraulic support test-bed system consists of embedded chip STM32as the lowercontroller and advanced programming language combination the upper computer software,this paper introduces the design of hardware and software.In the hardware aspect, mainly includes the selection of devices, design theelectromagnetic valve control circuit, data acquisition system and the communication of upperand lower machine, analyzes the interference of the system, and to take the correspondinganti-interference measures etc.; In the software aspect, mainly to improve the controllerfirmware programming and the function of control software of the test control. The design issimple and easy to operate interface. The whole project is focused on the field of domestic andprovide a set of advanced measurement and control system of Hydraulic Support Test-bed.Through the actual test in site, the measurement and control system of hydraulic supportcomplete the performance testing for Hydraulic Support Test-bed automatic/manual controland meet the MT312-2000specified requirements. The whole subject due to be applied toengineering practice, the cost is reasonable, the use of better and more practical.Finally, the paper is summarized and prospected.
