摘要
采用STC89C52单片机结合LM2596-5.0开关电压调节器、DS12C887时钟芯片、AT24C64串行存储器、74HC595移位寄存器以及接触式IC卡等器件,实现了对机场车辆速度的实时显示以及超速后的自行报警,并将超速情况以数据的形式存储到存储器中,可用IC卡对数据进行读取。该系统通过超速报警来提醒司机减速,从而减少车辆刮碰飞机等事件的发生。
This article designs an airdrome vehicle's excessive speed alarm system which uses STC89C52 singlechip,LM25965.0 simple switcher power converter,DS12C887 real time chip,AT24C64 serial EEPROM,74HC595 shift register and contact IC card.This design can display the vehicle ' s real time speed and alarm when its speed is excessive,and then the excessive speed will be stored in EEPROM as data types.The data in EEPROM also can be stored in IC card.This system 's purpose is reducing insecurity affairs such as vehicle hits aeroplane by alarming the driver to decelerate.
