摘　　要：为了便于技术人员对继电器进行筛选，本文提出了一种基于单片CPLD的微型电磁继电器时间参数（吸合时间、释放时间、触点回跳时间）的测试方法，充分利用CPLD的资源来实现继电器多个时间参数的测量，给出了测试电路的硬件结构及各个部分的电路原理图，并通过实验进行了验证．确定其量程为0～99．99ms，最小分辨率为1μs．该电路具有测量速度快、体积小、成本低和操作简单等优点．In order to help technical personnel select relay, this paper puts forward a method to test the time parameters （including operation time, release time and contact bounce time） of micro electromagnetic relay. This method is based on one CPLD and makes full use of its resource to implement the measurement of multiple time pa- rameters. The hardware structure and circuit principle diagrams of each part are given. Through experiments we de- termine that the range of time parameter tester designed in this paper is 0 - 99.99 ms and the minimum resolution is 1 μs. In addition, this circuit has other advantages such as fast measuring speed, small volume, low cost and easy operation.
