智能车速里程表的设计与制作

Design and Manufacture of Intelligent Speedometer

本文以单片机、霍尔传感器和温度传感器为核心元器件,设计和制作了一种智能车速里程表。里程表还具有水箱温度参数测量功能。实验结果表明,该方案切实可行。

Speedometer is an important instrument for driver to provide dynamic driving information in time. It has a direct impact on the safety of vehicles, especially in high-speed traffic of vehicles. In this paper, a microcontroller, Hall sensor and temperature sensor as the core components, the design and production of a smart speedometer. The design of the first Hall sensor to the wheel speed into a pulse signal, and then the signal into the microcontroller, and finally through the microcontroller as the core of the digital measurement system and powerful processing capacity, the LCD display the car speed mileage data results more Visual display to the user. In addition, the odometer also has a water tank temperature parameter measurement. The experimental results show that the scheme is feasible.
