How to measure the performance index of each parameter of a high-precision gas pressure reducing valve to meet the requirements? Become one of the most important tasks for R & D and testers. In the past, the test system of high precision gas pressure reducing valve was mostly based on the mechanized instrument and manual operation of scientific research personnel. The artificial error was large, the process was tedious, and more manpower and material resources were consumed. The purpose of this paper is to design an intelligent monitoring and testing system of pressure reducing valve based on sensor system to monitor the parameters of high precision gas pressure reducing valve. Based on the understanding of the performance parameters of the gas pressure reducing valve, a scientific test procedure is established, which conforms to the domestic and foreign standards for testing the performance index of the pressure reducing valve. Optional system in the automatic and semi-automatic mode of operation, save labor costs. According to the performance requirements of high precision gas pressure reducing valve, the monitoring and testing content of high precision gas pressure reducing valve is studied. The sensor system with high reliability and data acquisition module with high speed are selected to simulate signal generation. The digital signal generating module uses RS485 industrial control bus to set up the hardware of the test system and collects a lot of data in real time. The intelligent data acquisition and processing software of upper computer is written. The software adopts C language and is designed based on Microsoft Visual C 6.0 development platform. The generated data is stored in three dimensions, and the control of data acquisition is completed by combining with Access database technology. The test automatically generates the data record file, provides the history record inquiry. The effect of ambient temperature and humidity on the test results can be measured and simulated in real time. Friendly interface automation is high.
