摘要
介绍通过计算机的接口电路对电流与转速信号进行采集、处理 ,应用VC+ + 语言制作可视化界面 ,显示电流与转速的响应曲线及电磁时间常数与机电时间常数测试数值 ,实现了数字化的测试方法。该方法简单易行、测量精度高。
The sampling and processing for current signals and speed signals by the computer interface circuits are concerned.In order to display the response curve of current and speed,the testing value of electromagnetic time constant and electromechanical time constant,visual interface has been made based on VC++.The digital testing method has been realized.The method can be easily realized and has high precision.
