电缆网阻值测试仪的设计与实现

随着单片机技术的发展及其在测试领域的广泛应用，早期采用的人工作业对电缆网性能测定的方法已经不再适用。本文介绍了一种基于单片机技术的电缆网阻值测试仪。从电缆网阻值测试仪的功能与设计要求出发，阐述了总体设计方案，说明了该套设备的工作原理，描述了系统的硬件实施和软件设计，并对整套设备进行了实验验证。结果表明：设备满足了用户要求，提高了测试效率。

Design and Implementation of the Test Device for Cable Network

With the development of the MCU technology , and the more and more important func-tion, the method to check the cable network absolutely based on manpower is not appropriate. A design of the test device for cable network based on MCU is introduced. Based on the detection principle, a de-sign scheme is introduced. And the design of hardware circuit and hardware driver and application soft-ware are introduced in detail. Experimental results show that： the device fulfills the specification of the customs and inprove the effection.
