摘要
针对目前传统汽车仪表显示单元的可靠性差、不易布线等缺点,文中介绍了一种汽车仪表,它是以微控制器P87C591为核心,以步进电机和LCD为显示器件,对车速、发动机转速、行驶里程、冷却水温度和机油压力5个参数进行了实时的测量和显示,并且设计了CAN总线接口电路,以实现数据在CAN总线上的接收和发送。
Aimed at the shortcomings of bad reliability,hard wiring in traditional automobile instrument,this paper introduced an automobile instrument.It took the microcontrollers P87C591 as the controller core,and its display devices was stepper motor and LCD.It measured and displayed five parameters-speeds,engine speed,mileage,cooling water temperature and oil pressure in real-time.This design has CAN bus interface circuits,so data could be received and sent in CAN bus.
