When the vehicle speed exceeds the highest value set by the driver, the buzzer alarm to alert the driver to slow to achieve the purpose of proactive. To some extent it effectively solve the car speeding problem The working principle of the Hall sensor was introduced in this paper. The working process was described. It is used pulse-counting method to achieve the measurement of speed, and to display vehicle speed values through an intuitive LCD. Combination of hardware circuit design, software were designed bya modular approach using C51 program, such as the motor speed measurement module, alarm module, display module etc. All these programs were simulated through PROTEUSE. Key words: rotate speed measurement ; Hall sensor ; LED1602 ; Single chip puter 临沂大学 2014 届本科毕业论文(设计) 目录 1引言............................................................................................................................. 1 课题产生原因.................................................................................................... 1 课题的发展现状................................................................................................ 2 汽车超速报警器的未来前景............................................................................ 3 本设计的主要内容..........................................
