摘要
简要地介绍了一新型微机继电保护测试仪的软、硬件开发 ,该测试仪采用并行打印口通信 ,将原始数据处理后经打印口输出 ,以便编程控制调幅和调频。它是一个能自动加载测试 ,自动拟合曲线 。
The HW & SW design and development of a new type microcomputer test device for relay protections are introduced.The test device uses printer interface for communication.It deals with the original data,then outputs it from printer interface to control wave scope and frequency by programming.It is an automatic test instrument,which can automatically impose test load,protract curves,analyze and process data.
