介紹一種基于MSP430F2274單片機為核心的智能小車。小車采用超聲波測距技術實現自動避障,同時通過語音模塊來播報出小車與障礙物的距離。為了使測距不受溫度影響,用溫度傳感器實時檢測小車周圍環境的溫度并修正距離計算公式的參數,采用光電編碼器來檢測小車的速度,運用PID控制算法和PWM來控制小車的精確穩定的運行,從而達到預期的設計目標。

數字控制的交流調速系統所選用的微處理器、功率器件及產生PWM波的方法是影響交流調速系統性能好壞的直接因素。在介紹了正弦脈寬調制(SPWM)技術的基礎上,設計了一種以8098單片機作為控制器,以智能功率模塊IPM為開關器件的變頻調速系統。通過軟件編程,產生正弦脈沖寬度調制波形來控制絕緣柵雙極晶體管的導通和關斷,從而達到控制異步電動機轉速的目的。實驗結果表明,該系統可調頻率調電壓,穩定度高,調速范圍寬,具有較強的實用價值 Abstract: AC variable speed with digital control systems used microprocessors, power devices and generate PWM wave is the direct factors of affecting the performance AC speed regulation system. On the basis of introducing the sinusoidal pulse width modulation (SPWM) technology,this paper designed variable speed system which used 8098 as a controller, intelligent power module IPM as switching device. Through software programming, resulting in sinusoidal pulse width modulation waveform to control the insulated gate bipolar transistor turn on and off, so as to achieve the purpose of speed control of induction motors. Experimental results show that the system can adjust frequency modulation voltage, high stability, wide speed range, has a strong practical value.

利用單片機具有的智能程序控制的特點,設計了基于STC89C52單片機的"二極管特性測試器",可對二極管一般特性進行快速測試。通過穩定線性電流源給二極管加載恒定電流,然后由高精度模數轉換器測試其壓降,以此為基礎可判斷二極管好壞、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計制作過程中對二極管進行快速測試,以確定被測二極管是否滿足電路的設計要求。 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.
