摘要
电缆测试箱利用单片机控制,外加数码语音芯片及发光二极管实现了对多种专用电缆的测试,对有问题电缆给出语音提示,并通过发光二极管指出电缆中是哪一根芯线有问题。利用声、光的形式直观地对电缆进行判断,帮助维修人员快速确定电缆的故障部位,及大地缩短了电缆的维修时间。
This cable test box is used with monolithic integrated circuit control, the sur-numerical code speech chip and the light emitter diode to realize many kinds of special cable＇s tests, the question cable is given the voice prompt, and through the light emitter diode to point out that which core has the question in the cable. With the using of sound and light form, it carries on the judgment in-tuitively to the cable and helps the servicemen to determine quickly the cable＇s trouble location, and greatly reduces the time of cable maintenance.
