摘要
描述了利用单片机AT89C52组成微处理机控制系统 ,测量可调电位器的各种动态参数包括线性度、后冲点、动触点的噪声等 ,将所采样的值通过RS232C串行通信口传送至PC机。由上位机分析处理 ,按照给定的元件规格 ,判断其是否符合标准。
How to utilize the micro_controller AT89C52 to make up the control system is described,to test all dynamic parameters of variable resistor(VR)which include linearity,backlash,noise of moving contact,etc..The tested data is transferred to the host computer via RS232C seral port,and further disposed in PC.Finally the PC calculates the data,decides the VR passed or failed of the based on the specification.
