摘要
介绍了C8051F040型单片机的结构以及在其控制下的喷油器电磁阀驱动电路的设计。以电磁阀响应为目标,设计了在该单片机控制下的驱动电路,通过配置单片机的可编程计数器阵列(PCA)而产生高精度的,控制喷油时间长短的方波,并详细叙述了该驱动电路的硬件结构和软件流程设计。
The structure of the microprocessor in the Model of C8051F040 and the drive circuit for injector solenoid valve controlled by it are introduced. With the purpose of respond of solenoid valve, the drive circuit controlled by the microprocessor is designed. The high precision square wave by which injection time is controlled is produced with the help of configuration of PCA. The hardware and software of the drive circuit are described in detail.
