摘要
提出了一种基于PIC单片机绝缘电阻综合参数测试仪的设计方案。采用PIC16F877为控制芯片,结合经典的检流计法,实现了对绝缘电阻的极化指数、吸收比及电阻值的自动测量,测试数据可实时记录并通过LCD显示或微型打印机打印。通过该系统的开发,可以更大程度的提高绝缘电阻测量的自动化水平。
This passage presents a design of general parameters for insulation resistance tester based on PIC microcontroller.Combining the classic galvanometer method,and using PIC16F877,Realize the polarization of the insulation resistance index,absorption ratio and automatic measurement of resistance.Real-time test data can be recorded and LCD display or through the mini-printer.Through the system development,automation of insulation resistance measurement can be improved.
