基于单片机的汽车智能速度表的设计(汽车电气与电子课程设计)

摘 要：本智能速度表设计以单片机和光电传感器为核心，由信号预处理电路、80C51单片机、串口液晶显示电路、串口数据存储电路和系统软件组成。本身设计主要是计算汽车在一秒内轮子的转动圈数即转动频率，但考虑本设计的实际情况，为使电路简单，仅以转动频率来模拟汽车的速度，并将计得的速度通过LCD显示出来，速度显示每1秒钟刷新一次，并在实时速度超过设置的报警速度时发出报警声。司机可以根据不同的情况需要设计来设置合适的报警速度，以使司机能在合适的速度范围内安全行驶。

Abstract:  The intelligent speed meter design based on MCU and photoelectric sensor as the core, the signal pretreatment circuit, 80C51 single-chip microcomputer, serial LCD display circuit, serial data storage circuit and system software. Design of automobile itself is calculated in a second wheel rotation number namely rotation frequency, but considering the design of the actual situation, in order to make the circuit is simple, only to the rotational frequency to simulate the automobile speed, and the measured speed through the LCD display, display the speed of each of the 1 second refresh time, and in real time speed exceeds the set alarm when the alarm sound velocity. The driver can according to the different situation need to set suitable alarm speed, so that the driver can fit in the speed range of safety driving.
Key Words: SCM; SCM system; module; the LCD display module.
