智能型电动机软起动器控制电路板测试系统设计

摘要

The measurement of intelligent motor soft starter control circuit board performance parameter is an important means to develop a new product and guarantee product quality. Based on requirement analysis, an automatic measurement system of performance parameter for intelligent motor soft starter control circuit board 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 LabVIEW virtual instrument technology plat-form, 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 control circuit board. The hardware design was given and the working principles of this system were introduced; and the module design of system software was also introduced in detail. Practical application shows that the intelligent measurement system features high precision, strong disturbance attenuation, high efficiency, and easy operation and maintenance. Besides, it 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 control circuit board.%在需求分析基础上设计并实现了一种利用虚拟仪器技术构建的智能型电动机软起动器控制电路板性能参数自动测试系统．系统以工业控制计算机为核心，配置高精度数据采集卡和信号调理电路等硬件，采用先进的虚拟仪器技术——LabvIEw软件开发平台自行开发数据采集、分析、处理软件，实现了对智能型电动机软起动器控制电路板的自动测试．详细分析了系统总体方案设计，阐述了系统软件模块设计．经实际应用表明，该系统具有测试精度高、抗干扰能力强、检测效率高、操作简单等优点．
