摘　　要：针对工业图像处理流水线检测系统中,多机之间需要传输较大配置文件,并且配置文件需要实时更新的问题,本文着重介绍了一种基于MSComm串口通信控件的较大文件传输方案,MSComm采用事件驱动方式。本方案应用SD-PI09853-4S多串口扩展卡扩展了4个串口,通过自定义通信协议,在Visual C++环境下实现了多机之间串口文件的快速传输,传输结果准确无误并且整个传输方案已在实际的项目应用中得到验证,系统运行稳定,可靠。Based on the question of configuration file transform and real-time update for multicomputer in industrial image processing pipeline system, this paper introduces a big file transform method with Visual C＋＋ used MSComm in event-driver way. This method adds 4 serials by use serial card of SD-PI09853-4S and it realizes the serial file transform for multi-computer system by use self-defined protocol of serial communication. The method has used in project, the results show the system is reasonable and reliable.
