监控系统中远端信号的传输方法

The Transmission Methods of Far-end Signals in Supervisory System

监控信号在传输时,可以利用光纤或铜缆,传输速度的快慢跟传输介质及通道大小有绝对的关系。监控系统所要传输的内容有:影像、声音及控制讯号,无论是声音还是影像都可以转变成"数据",本文主要介绍了域内远端信号局端连线远端信号、网络远端信号的传输方法。

Supervisory signals may be transmitted by optical fiber or copper cable. The transmission speed is closely related with the transmission medium and the channel size. The contents transmitted include images, sound and control signal. The sound or the images may be transformed to ＂data＂. This paper mainly introduces the transmission methods of far - end signals in supervisory system.
