【正文】 l signals, be driven 46V, 2A below the motor. 2. 2 tracing module design Tracing module mainly posed by photoelectric sensor reflex. Photoconductive resistance of the resistance of the light with the surrounding environment changes, when the LTT white lines above, light emission strongly。 1. Project Design light by a sensor, the reality of the electric car is moving quickly degrees, bit, buy, transportation line shape when measured quantity of real condition, and will be measured quantity number according to preach sent to monolithic machine into line processing, but by single chip machine according to the measured by root different forms of several inspection according to real now to electric actuation vehicle wisdom can control system. This kind of square case can real now to electric actuation vehicle dynamic shape state into the shipment do real possession in system, control system spirit alive, can depend, pure degree is high, can full foot of each item of the stockings to beg. (1) straight epidemiological speed is tasseled straight epidemiological speed department with pulse width modulation gather speed is , its main electrical pulse width modulation by road system type variable change device, Jane says PWM variable change device. Adjustable speed by in the department of PWM experience. meanwhile open shut frequency rate is high, only on electricity barnado electricity sense of filter wave can be use to get to move very small straight pulse electric flow, electricity flow barnado electric capacity easily even tantras, department of low speed operation flat , adjustable speed stability van is surrounded relatively wide, can reach 1 000 left right. By on electrical flow wave shape than V M system, be in phase with flat to all electrical flow dynamic machine, electric heat consumption and hair loss than a small. With the sample by in open shut frequency rate is high, and if a fast speed of electrical machine ring should match close, fasten tasseled phase can be to get very wide frequency band, because of the fast speed ring should be good, dynamic configuration sexual can perturbation resistance can force is powerful. According to the root, with more than ensemble close and this set of electrical machine control project by tolerance of the quantity and electrical machine speed straight flow of hair, the exhibitor to adopt the project with a single extremely H type can be changed into change device inverse PWM line speed. photoelectric detection module design The intelligent car was stuck on the black line running on white paper road, so this module design need to detect shop on the black rubber belt drive area, including Run straight along the arc district and driving district two area. Because of the black and white paper to light reflection coefficient is different, can according to receive reflected light. The strength of the judge road the black line. This paper USES is simple and practical detection methods, namely the infrared detection method. Infrared detection method, . use
