摘要
现在市场上的里程表样式多种多样,但是很多里程表存在着汽车总里程数和车速不准确的问题,这就需要进行里程表的检测。该文提出了一种里程表检测仪的硬件设计,该设计采用ATmega16为核心的单片机系统,用变频器控制速度,实现了对不同调速比的里程表的检测。该里程表检测仪的系统电路简单可靠,用它来检测里程表方便且高效。
Now the odometers on the market have variety of styles,but there are many automobile odome- ter mileage and speed precision problems,which need to carry on the odometer test.This paper presents the hardware design of a odometer tester,the SCM system design using ATmega16 as the core,control the speed by frequency converter,realized the detection of different regulating speed odometers.The system circuit of the odometer tester is simple and reliable,which is convenient and efficient to test odometers.
