利用單片機(jī)具有的智能程序控制的特點(diǎn),設(shè)計(jì)了基于STC89C52單片機(jī)的"二極管特性測(cè)試器",可對(duì)二極管一般特性進(jìn)行快速測(cè)試。通過(guò)穩(wěn)定線性電流源給二極管加載恒定電流,然后由高精度模數(shù)轉(zhuǎn)換器測(cè)試其壓降,以此為基礎(chǔ)可判斷二極管好壞、檢測(cè)二極管極性和測(cè)試二極管伏安特性等,避免了用萬(wàn)用表測(cè)試只能測(cè)得極性而不知其特性這一缺點(diǎn)。可用于電子設(shè)計(jì)制作過(guò)程中對(duì)二極管進(jìn)行快速測(cè)試,以確定被測(cè)二極管是否滿足電路的設(shè)計(jì)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.
