一种基于单片机的汽车电子点火系统的设计

介绍了一种基于单片机的电子点火系统的设计方法。系统采用AT89C2051单片机作为控制单元,依据曲轴位置传感器、温度传感器、爆震传感器和节气门开度传感器及相关调理电路获得转速、温度、爆震和负荷信号后,对其进行运算处理,计算出点火提前角,给出点火控制信号,控制点火电路在适当的时刻点火。完成了系统的硬件设计和软件设计并调试成功。

Design of Automobile Electron Ignition System Based on single chip

A kind of electronic ignition system based on single chip is designed in this paper.The control unit of the system is AT89C2051 single chip.By the crank position sensor,the temperature sensor,the knocking meter,the damper opening sensor and the corresponding circuit,the state data of the running motor is obtained.After processing the data,single chip calculates the ignition angle of advance and gives the firing signal.The firing signal controls the firing circuit to fire the mixture of air and oil.The design of system hardware and system software is accomplished.The system has been debugged successfully.
