Research On Decompression Valve Monitoring Intelligent Test System

With the rapid development of the aviation and space industry, highprecision gas pressure reducing valve in the aerospace field development moreand more quickly, how to measure a high precision gas pressure reducing valveperformance index of the parameters whether meet the requirements, become aresearch and development personnel and testers one of the top priorities.Previous high precision gas pressure reducing valve testing system based on themechanization of meter and most scientific research personnel manual operation,human error is big, process trival, expend more manpower.This article is to design a sensor system based on the intelligent monitoringsystem of the pressure reducing valve testing precision of the pressure reducingvalve gas monitor all the parameters. Use of the gas pressure reducing valveperformance parameter index understanding,formulated the scientific testspecification processes, in domestic of foreign pressure reducing valveperformance index testing standards.Can choose in full automatic and semi-automatic system work mode of operation, save manpower cost.According to the performance request of the air decompression valve,formulation the decompression value’s monitoring test content. Build test system hardware, carries on real-time gathering to the mass data. The software uses the C++language, unifies the Access data bank technology, completes to the data acquisition control, automatic generated data record file, provide the historic record enquiry service. Can Real-time measurement andsimulate ambient temperature and humidity to test result influence. The human–machine interaction interface is friendly, the automaticity is high.
