摘要
提出了基于CAN总线技术的汽车仪表的研究与应用。该系统设计是以微控制器P87C591为核心,以步进电机和LCD为汽车仪表硬件平台,实现数据在CAN总线上的接收和发送。同时基于汽车工作环境的复杂,对系统的抗干扰进行了分析和设计。通过对CAN总线数据和各传感器数据的读取、处理和显示,该系统设计能够实时反映车辆的工况。
The system design of the motormeter based on CAN bus takes the microcontroller P87C591 as its core and the stepper motor and LCD as its hardware platform,so as to achieve the data received and sent on CAN bus.The anti-jamming of this system is analyzed and designed based on complicated working conditions.This system design can reflect the realtime working conditions of vehicles by reading,processing and displaying the CAN bus data and the data from each sensor.
