LabVIEW-based Adaptive Cyclic Voltage Regulator PCT Test System
Rare earth hydrogen storage materials are indispensable raw materials for nickel-metal hydride batteries and solid-state hydrogen storage devices.In the process of R&D and production of rare earth hydrogen storage materials,PCT curve(pressure-composition-isotherm)is an essential test performance curve.In order to solve the problems of low efficiency and cumbersome operation of PCT test system,a new PCT test system with adaptive cyclic pressure regulation was designed.This paper introduces the hardware structure design of the system,the basic test principle,a mathematical model and software structure design of the adaptive cyclic pressure regulation method,the data acquisition by using the USB-6002 data acquisition card to improve the accuracy of the collected data,and a test program based on Lab VIEW software with reasonable automatic test procedures is designed to reduce the difficulty of operation and improve the efficiency of automatic test.
