摘　　要：在小型或零星的多媒体教室实现对投影机的网络远程控制,仍然值得进一步研究。在此阐述Windows服务的基本特性,分析服务器端网络数据帧与串口数据帧通信协议的转换,论述基于Windows服务的软件设计流程。进而提出在无网络中控的情况下,对投影机实现远程控制的"零成本"解决方案,并介绍投影机远程冷启动开机和延时关机的方法。基于Windows服务的数据通信有着在特殊应用中的优势。It is still desirable to study and develop remote control on the projector in miniature or scattered multimedia classroom. The basic characteristics of Windows service is elaborated in this paper, and the communication protocol between network data frames and serial interface data frames is ananlyzed,and the software design process based on Windows service is discussed. Furthermore,a solution with zero- cost of the remote control on projector has been put forward when there is no availability of central network control. The method of remote coldstart - on and postpone - off of projector has been introduced at the same time. The data communication based on Windows service is innovative points. The advantage of this technique in some special application has been illuminated.
