摘要
国内外现有的远程监控系统多基于光纤,而光纤如遇到机械冲击、碰撞造成断缆或断芯后,很难快速修复,且修复设备复杂.针对这一个问题,价格相对便宜、维护十分简单的极低比特率双绞线成为解决的方案.以TI低成本DSP芯片F206为例,介绍了一种基于这一芯片的极低码率双绞线视频图像监控系统,给出了整体方案,并就系统实现的一些关键点进行了详细解析.图5,参5.
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. In order to solve this problem, people have found a solution of using the longrange supervision system transmitting on the twistedpair at an extereme lowbit rate with less cost. The article aims to introduce a twistedpair video supervision system at an extreme lowbit rate based on lowcost TI DSP F206. It is an economical and practical longrange supervision system that possesses broadcasting ability. The author not only offers a complete scheme but also elaborates on some key points.5figs.,5refs.
