基于PIC单片机的汽车车身集中控制系统的硬件设计

The Hardware Design of Auto Body Centralized Control System Based on PIC Single-chip Computer

介绍了汽车车身集中控制系统的硬件和软件设计,以PIC16F74单片机为控制器,对工作状态信息进行检测,读取测速脉冲数,根据需要满足的功能进行运算处理,发出的相应控制信号经驱动和放大电路来控制门锁、闪光器、蜂鸣报警器等电器元件.将分散的控制功能进行集中整合和扩展,使所有功能在一块单片机上进行控制.整个系统体积小、重量轻、功能完备.

This paper introduced auto body centralized control system hardware design and outline of its software design.PIC16F74 microcontroller was used as the controller,work status information to detect,read gun pulse number,in accordance with the need to meet the specific functions of this processing,issued various corresponding control signal and driving amplifier circuit to control door locks,flash devices,faint buzzing alarm,and other electrical components.Scattered centralized control function was integrated and extended all functions in one microprocessor control.The whole control system is small in size and light in weight.It can provide convenience to the automobile manufacturers and users.
