智能车速里程表的硬件设计与制作
[摘要]:近年来随着计算机在社会领域的渗透, 单片机的应用正在不断地走向深入,同时带动传统检测、控制技术日新月异。在车辆高速行驶过程中,车速里程表是为驾驶员及时提供动态驾驶信息的重要仪表,它的好坏直接影响到车辆行驶安全。本文以单片机、霍尔传感器和温度传感器为核心对智能车速里程表进行了设计。该系统将温度传感器输出的数字信号和霍尔传感器输出的脉冲信号,送入单片机并进行处理和运算,最终汽车的速度里程数据通过液晶显示器更加直观的显示给用户。本课题运用先进的电子技术、传感器测量技术和计算机智能技术,设计制作了智能车速里程表,该仪表具有精度高、速度快、显示直观的特点。

Abstract:Along with the computer technology permeating in the social realm in recent years, the applications of SCM (single chip microcomputer) are constantly deep, and it drives the traditional detection and control technology changing with each passing day at the same time. In high-speed vehicles, speedometers are important instruments providing dynamic driving information for drivers. The traffic safety is directly affected by its quality. An intelligent speedometer is designed using Hall sensor, temperature sensor and SCM as core components. The digital signals provided by temperature sensor and pulse signals provided by Hall sensor are processed and calculated by SCM. Then the date of speed and distance are displayed intuitively by LCD. The intelligent speedometer, which has characteristics of high precision, high speed and intuitive display, is designed and manufactured using advanced electronics, sensor technology and intelligent computer technology in this project.
