标准逻辑器件检测系统的设计

Design of Standard Logic Devices Detection System

实验教学中需要对器件进行大量的检测,因此设计和制作标准逻辑器件检测系统是十分需要的。利用单片机设计这样的检测系统是一个较好的选择,它能够提供所需要的逻辑资源,并且价格便宜。研制的标准逻辑器件检测系统基于MCS51系列单片机实现,该系统通过键盘输入被检测器件的型号,利用数码管和发光二极管显示当前正在被检测的器件型号以及检测结果。实际使用表明,该检测系统具有成本低、升级容易以及使用方便等特点,同时,其硬件电路和软件代码对扩展学生掌握数字系统设计方法也具有很大的价值。

Experimental teaching requires a lot of testing on the device,so the design and production of standard logic device detection system is needed.The detection system with MCU is a better choice,it can provide the required logic resources and the price is cheap.This article developed the standard logic device detection system based on MCS51 series.The system keyboard input is model number of detected device.Nixie tube and LED display currently tested models and test results.Actual use show that the detection system has low cost,easy upgrade and convenient application etc.while its hardware circuit and software code for students to master digital system design method is also of great value.
