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.

在航電系統(tǒng)維護(hù)過(guò)程中,為解決定位故障的效率和降低維修成本等問(wèn)題,提出了基于ICD(Interface Control Document,接口控制文件)的1553B總線的信息監(jiān)控系統(tǒng)模型。該系統(tǒng)運(yùn)用數(shù)據(jù)采集卡對(duì)總線中傳輸?shù)男盘?hào)有無(wú)失真、偏差等電氣特性進(jìn)行檢測(cè),并使用1553B通訊卡通過(guò)測(cè)控軟件LabWindows/CVI編程與ICD數(shù)據(jù)庫(kù)的動(dòng)態(tài)鏈接,實(shí)現(xiàn)總線信息的解析和故障的判斷。與傳統(tǒng)的維護(hù)過(guò)程相比,這種模型能夠從信號(hào)的電氣特性以及信息的解析等全方位的去檢測(cè)判斷故障的來(lái)源,并且能夠廣泛在其他1553B總線系統(tǒng)內(nèi)擴(kuò)展應(yīng)用。驗(yàn)證表明該監(jiān)控系統(tǒng)可以對(duì)總線信息進(jìn)行快速有效地監(jiān)測(cè)分析,能滿足應(yīng)用需求。 Abstract: In the process of avionics system maintenance, to solve the problems such as improving the efficiency of fast orientation to troubles and reducing maintenance cost, system of 1553B bus information monitor model based on ICD was proposed. The system observed whether the data which transmitted on the bus appear distortion and deviation by using data acquisition card. And using 1553B communication card programming of the measure software LabWindows/CVI and the dynamic linking of ICD database, message analysis and fault estimation could be realized. Compared with traditional maintenance, this model can all-dimensionally detect and analyze the source of faults from both electrical characteristics of the signal and message analysis, and it can be widely applied in the other 1553B system. Experiment shown that this monitor system can effectively detect and analyze the bus message and can meet the application requirements.
