The design of synchronous control of the hydraulic load beam mobile computer
[Abstract]For coal mining safety,Test the performance of hydraulic support for mine, and design the test rig of hydraulic support.The main component of the hydraulic support test rig is the load mobile beam,It is mainly controlled by four lift hydraulic cylinder, in order to make the four cylinder stationary synchronous mobile,In this paper, a computer synchronous control system for a load mobile beam is designed. 
  This paper introduces the research situation of hydraulic support loading platform and synchronous control technology,Proportional control of hydraulic parameters for selecting solenoid proportional valve;Then the design of the hydraulic proportional control circuit and the selection of hydraulic components;The hardware of the computer control system is composed of the hardware and the selection of hardware is carried out. The electrical control scheme is designed.The four cylinder synchronous control and plug pin control electrical schematic diagram are given,At the same time according to the use of the design of the panel layout plan;Then it is the software design of the system,With a good man-machine interface using C# programming language design software,And can achieve the relevant test requirements;Finally, the system installation and debugging, inspection work, the system is stable and reliable, it can meet the work requirements.
