一种远程网络摄像机系统的设计与实现

Design and Implement for Long-Range Net Camera System

目前远程视频监控系统已经成为计算机监控系统的重要分支,同时也是人们研究的热点和难点之一。国内外现有的远程监控系统大多基于光纤,而光纤如果遇到机械冲击、碰撞等都会造成光缆断缆或断芯,光缆断裂后,很难快速修复,且修复设备复杂,普通用户根本无法进行焊接修复,再加上光端机价格较高,这些都限制了光纤远程监控系统的应用和普及。为了解决这个问题,人们找到了价格相对便宜、维护十分简单的极低比特率双绞线解决方案。文中以基于MODEM直连方式的矿井远程视频监控系统为例,介绍这套非常经济、实用且具有广播能力的远程矿井网络摄像机系统。

The long-range video supervision system has become the important branch of computer supervisory control system at present, and at the same time the research concerned involves much difficult while drawing much concern. The now available longrange supervision system at home and abroad is based on the optical fiber mostly, and if the optical fiber runs into that the machinery lashes and colliding optical fiber may split or break. Once splitted, it＇s hard to be restored because of the sophisticated equipment, and ordinary user can＇t restore it by means of the welding at all. Moreover the high price of light transmitter and light receiver limits the application and popularization. In order to solve this problem, people have found a solution of using the long-range su- pervision system transmitting on the twisted-pair at an extereme low-bit rate with less cost. The article aims to introduce a twistedpair net camera system at an extreme low-bit rate based on MODEM work with direct link. It is an economical and practical longrange net camera system that possesses broadcasting ability.
