| Light rail trains, air compressor provide900kPa compressed air for locomotivebrake, which is mainly used for the locomotive braking system and other pneumaticcomponents provide air supply. So the quality and reliability of the air compressor ofthe train has a deep relationship with safety and reliable running. In order to ensurethe efficient and reliable operation during the running of the air compressor, need tobe the necessary performance monitoring.This test rig measurement and control system by GB3853air compressionmachine machine performance test methods and JTNPT5NPT5type air compressortest and acceptance of the technical conditions.The design and manufacture of aircompressor performance test rig are introduced in the design principle, designs theoverall scheme of test-bed, and then this basis, the concrete design of the hardwaresystem and PC software system. Hardware is based on Siemens S7-200PLC as themain controller, according to the concrete in order to realize the function, the designof the hardware system mainly includes the test-bed gas path structure, console,control circuit design; Systems software is software based on c#the upper machinethrough the OPC technology and detection of PLC real-time communicationplatform.This test rig measurement and control system in May, when necessary, set thetest mode (automatic/manual), automatic test data, record test results and the testtime and storage, can print the test results, and can query the print history. Test rig isequipped with abnormal alarm, the safety of the pressure, temperature overrunautomatic stop function. And has the high testing precision, safe and reliableperformance, convenient operation, etc. In addition, this test rig the operation issimple, intuitive, user interface with Windows style of humanized design, theinterface is clear. |
