为解决实际测控系统中在控制中心的上位机和控制功能设备的下位机之间传送命令和文件的问题,在讨论VC++6.0中MSComm控件的基础上,通过制定通信协议、给命令和文件加入标识构成包进行传送,从而正确地区分了命令和文件.实验表明,基于该通信协议,可以成功地传送命令和多类型文件. -To address the actual measurement and control system in the Control Center PC and control functions of equipment under the digital transmission between orders and documents, in discussing the VC++ 6.0 in MSComm control on the basis of the communication protocol through the development to the orders and adding logo files constitute a packet transmitted, thereby correct distinction between the orders and documents. The experimental results show that based on the communication protocol, you can successfully send a command and multi-type documents.
