【正文】 、自動(dòng)跟蹤器 智能小車的跟蹤原則 跟蹤意味著小車沿著白色地板上兩厘米寬的黑色導(dǎo)航路線運(yùn)行。輸入電壓高于 時(shí)， 模塊可以輸出 的穩(wěn)定電壓，實(shí)現(xiàn)低能量消耗。 PWM 模塊上的端口 PA0，PA1， PA2 and PA3 分別控制 DC 馬達(dá)和轉(zhuǎn)向馬達(dá)來執(zhí)行一些功能，比如前進(jìn)，后 退和轉(zhuǎn)彎等等。 、核心模塊的設(shè)計(jì) 小車的控制器采用了 ATMEL 生產(chǎn)的 AT91SAM7S256 微處理器 。 關(guān)鍵詞： ARM；智能；跟蹤 21 世紀(jì)，隨著科學(xué)技術(shù)的發(fā)展，關(guān)于智能小車及其相關(guān)技術(shù)的研究已經(jīng)成為該領(lǐng) 域 的焦點(diǎn)。其所使用的核心元件為嵌入式 ARM7 芯片。 too close distance may damage the sensor and intensify the effect of diffuse reflection. (2) Due to mon DC motor adopted for it, the control of the car is not accurate and stable enough to perform a break turn unless several same photoelectric sensors are added to the bottom of the car. 5 Conclusion Intelligent car is a front subject which has synthesized many other subjects and has a widelyapplied prospect. It particularly helps to develop the present Chinese undergraduates’ imagination, practical abilities, team awareness, and hitech innovation capacity.

(Beijing Information Science amp。 Control Technology （ Beijing Information Science amp。 L2 and R2 are secondary sensors. The distance between the two ipsilateral sensors should nor be more than width of the black direction control. When the car is running, the black guide line is always kept right between the two primary sensors L1 and L2. When the car goes off the black line, the primary sensors detect it, and thus the ARM7 chip detect level jump and execute the preprepared correction program to navigate the car back onto the track. The secondary sensors are actually a backup for the primary. Once the car offsets the track for inertia, beyond the reach of detection of the primary probes, the secondary perform to correct the motion of the car, so as to ensure the reliability of tracking. 3 Design of software The software is developed in C language in Keil Uvision3 IDE, debugged and downloaded in JLink ARM emulator. JLink is a JTAG emulator which was brought out by SEGGER in USA to support emulation chips with ARM core. It works with IDEs such as IAREWARM, ADS, Keil, WINARM, and RealView, supports all ARM7/ARM9 core chips simulation, and seamlessly connects with various IDE by RDI interface. Easy to operate and to connect to, it is the most practical tool for
