[Abstract]:Screw air compressor, with its outstanding advantages of energy saving and stability, has been widely used in various fields of modern production.According to the relevant national and industry standards and the actual production test environment, based on the full analysis of the system requirements and understanding of the current situation of the industry, this paper designs an industrial control machine as the core.The test system of air compressor is composed of data acquisition card and high precision sensor.Firstly, the overall design of the air compressor test system is completed, the test method and flow chart are defined, and the design ideas of hardware and software are planned.According to the operating characteristics of screw compressor, field environment, mechanical characteristics of monitoring point selection, select high-performance sensors and Yanhua multi-function data acquisition card PCI-1712 to complete the data acquisition.The software completes the data processing and analysis, gives the macro and micro indexes of the air compressor test, makes friendly man-machine interface, and generates the test report.Because the air compressor performance index calculation includes the main engine axis power parameter of the air compressor, this paper also studies the frequency converter electrical parameter test.The working principle of frequency converter is briefly described, and the measuring principle of its electrical parameters and the method of spectrum analysis and calculation are emphatically analyzed.The spectrum leakage, fence effect and aliasing effect in spectrum analysis are discussed. The windowed interpolation correction method is given to reduce the measurement error, and the simulation results are given by MATLAB.The air compressor test system designed in this paper has been debugged. The test results show that the system can quickly and accurately collect the state of the air compressor, give the macro and micro performance parameters of the air compressor, and realize the basic function.It can solve this engineering problem and provide important reference for subsequent design and production.
