说明：  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.)

再者个网络时代，伴随着有线网络的广泛应用，以快捷高效，组网灵活为优势的无线网络技术也在飞速发展。本文将简单介绍无线局域网相关技术及其相对有线局域网的优势，并具体介绍如何通过VC6.0设计和实现能同时运行在有线局域网和无线局域网上的简单通信软件。(network era, along with cable network widely used to provide a quick and efficient. flexible network edge wireless network technology is also expanding rapidly. This article briefly introduces wireless LAN technology and its relative advantages of the wired LAN. and the specific details of how VC6.0 design and implementation can also run on the LAN cable and wireless LAN simple communications software.)

CPing依据ICMP协议实现, 可解析域名和IP, 可设置发包数量,统计丢包率(CPing based on ICMP protocol implementation can resolve domain names and IP, you can set the number of contracting, statistical packet loss rate)

基于网络的视频监控系统 随着时代的发展，人们对安全防范也越来越重视，而数字化视频监控系统在音视频录像、报警录像联动、硬盘存储、多画面显示等方面都有突出表现，因此在安防领域逐渐占有了一席之地。本文提出的基于网络的视频监控系统实现了对数字硬盘录像机的控制功能，其远程客户端软件可以同时播放四路具有高达Dl分辨率的图像数据。 第一章论述了视频监控系统和数据压缩技术的发展动态。 第二章对客户端软件的开发环境及平台进行了选择，并就其中使用的关键技术:windows sockets编程技术、windows多线程技术、windows图像显示技术、MPEG-4编解码与数据传术技术、流媒体技术做了简介。 第三章详细论述了客户端软件的设计及实现。包括客户端软件的整体设计和各模块的设计实现，最后给出了实现结果。 第四章是论述了实时流媒体播放器的设计和实现，包括主要模块设计实现 (网络接收模块、解码模块、显示模块、操作控制模块)、其他模块设计实现(显卡能力探测模块、表面管理模块)、性能优化(缓冲、共享内存、线程模型)。 第五章对系统进行了总结，并为系统进一步发展提出了展望和规划。 (network-based video surveillance system with the development of the times, people are increasingly security attention, and Digital Video Surveillance System in video and audio video, police video linkage, hard disk storage, Multi-screen display, and other aspects outstanding performance in the field gradually Security occupies a place. This paper presents the network-based video surveillance system for the digital disk video recorder to the control function, its remote client software can be broadcast simultaneously Four Dl with high-resolution image data. The first chapter of the video monitoring system and data compression technology developments. Chapter II of the client software development environment and platform choices, and the use of the key technologies : Programming windows sock)
