资 源 简 介

  利用单片机具有的智能程序控制的特点,设计了基于STC89C52单片机的"二极管特性测试器",可对二极管一般特性进行快速测试。通过稳定线性电流源给二极管加载恒定电流,然后由高精度模数转换器测试其压降,以此为基础可判断二极管好坏、检测二极管极性和测试二极管伏安特性等,避免了用万用表测试只能测得极性而不知其特性这一缺点。可用于电子设计制作过程中对二极管进行快速测试,以确定被测二极管是否满足电路的设计要求。

  Abstract:

  By making good use of the intelligent control function of the Micro Controller Unit (MCU), the diode trait tester was designed based on the STC89C52,which could be used to test the trait of a diode rapidly. By loading constant current to diode through the stable linear current source, and measuring the voltage drop of the diode by high-precision analogue-to-digital converter (ADC), it can judge whether the diode is good or not, distinguish the polarity of the diode, and test the trait that the diode, which can avoid the fault of using a multimeter can only measure the polarity but not the trait. This device can be used to test the trait of a diode quickly,and to make sure that whether a diode can be used in the electronic design or not.
