Design on measurement and control system automatic test bench of valves for shield support

Abstract Hydraulic support in coal mining plays a key role in the process, the hydraulic valve performance is good or bad will directly influence to the coal  mining  working face operation, want to be able to improve the quality of maintenance of hydraulic valve, it is necessary to have reliable means of maintenance, but the country is lack of the corresponding test equipment, so to study the hydraulic support valve test-bed can for hydraulic valve testing provides the necessary test conditions。

First of all, we introduced the research background and development status of the valve test bench for hydraulic support, analyzed the deficiency and development trend of domestic and international research, and put forward their own suggestions for improvement,

Secondly, the composition and principle of the mechanical working mechanism and the principle of the valve test bench for the hydraulic support are described。 And on this basis, the design of the control test bench test process electrical schematic。

Thirdly, the paper introduces the key electrical components used in the electrical principle diagram of the valve comprehensive test bench of the hydraulic support, and the selection of the components in detail。

Then, this paper introduces the function of the software interface design process, the composition of the interface, the main function of the software, and also briefly describes the operation of the software method。 And the design flow chart is  given。

Finally, the installation and debugging of the test bench are given, and the detailed debugging process is described。
