Abstract
80C51 is a 8 bit single chip computer.Its easily useing and multi-function suffer large users. This article introduce the CCUT graduation design with the 80C51 single chip copmuter.This design combines with scientific research object. This system regard the request of the topic, adopting 80C51 for controling core,super sonic sensor for test the hinder.It can run in a high and a low speed or stop automatically.It also can record the time ,distance and the speed or searching light and mark automatically The electric circuit construction of whole system is simple, the function is dependable. Experiment test result satisfy the request, this text emphasizes introduced the hardware system designs and the result analyse.
The adoption of technique as:
Reduce the speed by program the engine;
efficient application of the sensor;
The adoption of the new display chip.
Keywords 80C51 single chip computer、light electricity detector、PWM speed adjusting
