Design of performance parameter automatic measurement system for intelligent motor soft starter

The measurement of intelligent motor soft starter performance parameter is an important means to develop new product and guarantee product quality. Based on requirement analysis, an automatic measurement system of performance parameter for intelligent motor soft starter based on virtual instrument technology was designed and implemented. This system was composed of industrial computer, data acquisition card and signal conditioning circuit, etc. Using Lab VIEW virtual instrument technology platform, the related test and data processing program codes were developed, and its high-speed data acquisition and data processing satisfied the needs of ex-factory performance parameter measurement for intelligent motor soft starter. The hardware design was given and the working principles of this system were introduced, the module design of system software was also introduced in detail. Practical application shows that the intelligent measurement system features with high precision, strong disturbance attenuation, high efficiency, easy to operate and maintain, and can improve the design and performance of products, which can be widely used. The system provides an effective way to design the performance parameter measurement system for intelligent motor soft starter.
