Intelligent hydraulic test instrument Abstract
The design for the intelligent hydraulic tester design, intelligent hydraulic tester is a kind of instrument can detect the hydraulic system flow, temperature, pressure,, due to the mechanical automation equipment, hydraulic system occupies a important position, so the reliability of the hydraulic system in engineering operations have become increasingly demanding, and test instrument for hydraulic system will provide reliable hydraulic parameter for engineering inspection, this design mainly for testing general situation, structure composition and SCM system development process are introduced. Firstly, the hardware system is designed, and the hardware system is designed, including power module, multi-channel signal acquisition and conditioning module, digital display module, USB communication module, CPU master module. Secondly, on the intelligent hydraulic pressure tester of the underlying software system development were briefly introduced, will need to implement the function with software system design, can complete on most of the hydraulic system pressure, flow rate, temperature detection, can provide reliable basis in the hydraulic system of optimization design and fault diagnosis.
