Development Of Pressure Difference Signal Device Detection Software And Design Research Of Automatic Pressure Regulating Device

There are three types of pressure differential signal device in an enterprise.Each type has ten processes.Each process has twelve pressure values to be checked and recorded.The workload of manual recording is large and error prone.The developed detection system solved some previous problems,such as huge workload and high error rate,at the same time it improved the efficiency of product testing.In addition,this article carried out technical research for undeveloped fully automatic pressure regulating device,which could improve the degree of automation and detection accuracy,provide a good program reference for research and development of new automatic test bench.The main contents are as follows :Research status of hydraulic detection system at home and abroad,including hydraulic test bench,computer aided testing technology and servo motor control technology.Control system design of pressure difference device test bench,including the design of control circuit,hardware model selection of control system.Introduced the working principle of pressure difference signal device and the testing principle of pressure difference test bench,draw the electrical schematic.Development of the testing software,including pressure differential signal device detection software development,serial communication module,voltage acquisition and determination module,the form selection and switching module,data storage module and the interface automatically displays the programming module to achieve multi-species enterprise pressure signal under different operating conditions The data is automatically collected and stored automatically.Design and research of automatic pressure regulating device,introduced its components and working principle.Selected its hardware,finished the calculating of regulator pump and draw the structure.Carried out the elastic modules test of oil volume under low pressure with sets of test experiments.The experimental data were analyzed.The performance test system developed has delivered to the cooperative enterprise and reflect well.The test bench development scheme has also be accepted by enterprise and could provide reference value for the development of new test bench.
