摘要
当前随着城市规模的扩大及其当前国内经济的快速发展,使得人们对交通的需求量越来越大。而国内出现车辆的数量较多,而道路的数量有限,使得道路的通行较为堵塞,交通事故较为频发,当前很多用户会经常超速进行行驶,也是造成当前马路上车祸的主要原因之一。因此设计一款系统较为完善的检测系统来对车辆进行监测具有重要研究意义。
此次设计一款基于单片机的超速提示系统设计,采用霍尔传感器对当前的车速进行实时监测,监测到当前的速度大于设置的最大值进行声光报警,用户可以通过显示屏查看当前的速度值,通过按键对速度最大值进行设置,通过按键可以调节PWM脉冲,从而控制电机不同的转速,此外为了节约能源,此次设计通过太阳能板对锂电池进行供电,从而给整个系统进行供电。

ABSTRACT
At present, with the expansion of the city scale and the rapid development of the current domestic economy, people’s demand for traffic is increasing. However, in China, there are a large number of vehicles and a limited number of roads, which makes the road traffic more clogged and traffic accidents more frequent. At present, many users often drive over the speed limit, which is also one of the main reasons for the current road accidents. Therefore, it is of great significance to design a relatively perfect detection system for vehicle monitoring.
This design is based on the MCU overspeed prompt system design, the use of Hall sensor for real-time monitoring of the current speed, monitoring the current speed is greater than the maximum value of the set sound and light alarm, the user can view the current speed through the display screen, through the button to set the maximum speed, through the button can adjust the PWM pulse, In order to control the different speed of the motor, in addition to save energy, the design through the solar panel for the lithium battery power supply, so as to power the whole system.
Key words:overspeed alarm; Hall sensor; Solar energy; Single chip microcomputer
