基于Socket和多线程的远程监控系统

探讨了基于Socket以及多线程技术的远程监控系统的设计和实现，介绍了系统设计的总体方案，并在VC＋＋6．0编程环境下实现了一种基于局域网的监控系统。Socket套节字作为目前最流行的网络通信应用程序接口之一，利用它可以方便地实现局域网内的数据传输。传统的单线程程序中，视频数据的鳊码、解码、传输不能同时进行，导致传输效率很低。为此，提出了多缓冲区多线程结构，有效地提高了视频数据的传输效率。实验证明，系统能有效地实现一点对多点的实时监控。

Remote Monitoring and Control System Based on Socket and Multithread

The development of remote monitoring and control systems based on Socket and multithread technology is described.The scheme of the system is introduced and a LAN based system is realized in VC++6.0 environment.The encoding,decoding and transmission can not be disposed simultaneously in traditional single-threaded programs,which lead to lower efficiency.Socket,a popular network communication API(application program interface),can achieve data transmissions conveniently on LAN.A socket based multiple-buffer multithreading configuration is proposed to improve visual data transmission efficiency,which can achieve point-to-multipoint real-time monitor efficiently.
