Electric intelligent car based on SCM

Through research and to realize a photoelectric sensor for sensitive components ,with AT89C51 as control core electric tracing of intelligent control carbonylation-the car ,the system is also including dc motor ,L9110 chips and LM324 comparator etc. The design USES AT89C51 as intelligent car core controller.

The system takes microcontroller as control core and realization of electric before Enter ,back ,turn left and right turn function .Through the Angle sensor detection the seesaw Angle change ,use incremental pl algorithm to control the electric car for balance ,and using photoelectric sensor detection black line ,make the electricity Actuation vehicle in the course of driving keep linear motion and don’t skip from atrium .

1. Project Design

Light buy 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 buy single chip machine according to the measured buy root different forms of several inspection according to real now to electric actuation vehicle wisdom can control system .This kind of square case 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 bed .(1)straight epidemiological speed is tasseled straight epidemiological speed department with pulse width modulation experience .meanwhile gather speed is experience .meanwhile ,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 experience .meanwhile ,adjustable speed stability van is surrounded relatively wide ,can reach 1000 left light .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 buy in open shut frequency rate is high ,and if a fast speed 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 .
