基于C8051F040单片机的喷油器电磁阀驱动电路设计

Design of Driving Circuit for Electromagnetic Valve Based on C8051F040 Singlechip

设计了C8051F040单片机控制下的电磁阀驱动电路,包括硬件结构和软件流程设计,实现了高速电磁阀的快速开闭。使用Visual Basic设计了与F040通讯的人机交互界面,该交互界面实现与F040传输数据的目的,同时可实时显示电磁阀喷油过程中电磁阀阀心的电压值变化。

The paper designs the driving circuit of electromagnetic valve controlled by C8051F040 singlechip, including hardware configuration and software program. The circuit could make the electromagnetic valve open and close fleetly. Using Visual Basic designs the user- computer interaction interface which communicates with F040. This interface realizes the purpose of person and F040 transmitting date, synchronously it can show the voltage＇ s change of the electromagnetic valve＇ s center during oil spraying of electromagnetic valve.
