提高变电站视频图像传输质量的新型传输方法

New Transmission Method of Improving the Quality of Substation Video Image Transmission

变电站视频监控系统视频图像传输方式采用的是通过同轴电缆(即2M线)经通信光纤通道传入监控中心的,这种方式存在传输带宽小、信号需要封装和解封装过程以及中间传输环节较多等问题,导致视频图像传输质量不高以及传输中断等现象。结合阜阳供电公司网络建设实际,通过以太网网线经信息广域网将视频和图像传送到监控中心的新型传输方式,该方式能够解决前者存在的问题,使视频图像传输质量得到大大提高。

The substation video monitoring system video image transmission mode adopt the coaxial cable(2M line),transfer to the monitoring center through communication optical fiber channel,this mode has many problems such as small signal transmission bandwidth,signal need for encapsulation and decapsulation process,and more intermediate transmission link etc,leading to the quality of video image transmission is not high and the transmission interruption phenomenon.Combined with the actual network construction of Fuyang power supply company,the video image is transferred to the monitoring center using the Ethernet cable through wide area network;this method can solve the existing problems in the former,so that the transmission quality of video and image is greatly improved.
