利用單片機(jī)具有的智能程序控制的特點,設(shè)計了基于STC89C52單片機(jī)的"二極管特性測試器",可對二極管一般特性進(jìn)行快速測試。通過穩(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)換器測試其壓降,以此為基礎(chǔ)可判斷二極管好壞、檢測二極管極性和測試二極管伏安特性等,避免了用萬用表測試只能測得極性而不知其特性這一缺點??捎糜陔娮釉O(shè)計制作過程中對二極管進(jìn)行快速測試,以確定被測二極管是否滿足電路的設(shè)計要求。 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.

生活中許多目標(biāo)的高度和水平距離需要進(jìn)行測量。目前主要的測量方法,仍以傳統(tǒng)的皮尺丈量為主,測量效率不高,有時還很不方便,沒有技術(shù)成熟的數(shù)字式測高測距產(chǎn)品。以基本的數(shù)學(xué)方法為理論依據(jù),利用遙控小車做為載體,采用角度傳感器測量角度、霍爾傳感器測量水平距離等,通過單片機(jī)LM3S615進(jìn)行數(shù)據(jù)計算,實現(xiàn)了對待測目標(biāo)物體的高度、水平距離等數(shù)據(jù)的快速、精確和數(shù)字式的測量,高度測量精度可達(dá)99.06%,水平測量精度則可達(dá)98.06%。 Abstract: In our lives, the height and horizontal distance of some goals are needed to be measured. Because the currently used methods are still traditional tape-based measuring methods, and the measuring efficiency is low and inconvenient so some kinds of digital and portable measuring methods or instruments are needed. Based on the basic math theory, this paper designed and manufactured a portable, digital and remote controlled measuring mobile small vehicle, which assembled with angle measuring sensor for angle measurement and Hall sensor for horizontal distance measuring. MCU LM3S615 calculated the height and horizontal distance data gotten from these sensors. The measuring process is simple, the measuring results are more accurate and the measuring efficiency is higher than traditional measure instruments. The accuracy of height and distance measurement can reach 99.06% and 98.06%.

在工作控制和智能化儀表中,通常由微型計算機(jī)進(jìn)行實時控制及實時數(shù)據(jù)處理。計算機(jī)所加工的信息總是數(shù)字量,而被控制或測量對象的有關(guān)參量往往是連續(xù)變化的模擬量,如溫度、速度、壓力等等,與此對應(yīng)的電信號是模擬電信號。計算機(jī)要處理這種信號,首先必須將模擬量轉(zhuǎn)換成數(shù)字量,這一轉(zhuǎn)換過程就是“模/數(shù)轉(zhuǎn)換(A/D)”
