The solution of node light -end machines on road monitoring video transmission: The transmission system of the road monitoring sub -center is relatively complicated, there are very scattered, there are concentrated and scattered, and the distance of various images is very inconsistent. Dozens or even hundreds of kilometers. The most intuitive and simplest design is to transmit point -to -point video light -end machines. The plan is characterized by simple design, but requires a lot of optical fiber resources. Another solution is to concentrate with point -to -point light -end machines with a few ways to transmit it with a point -to -point light end machine. This scheme saves some optical fibers, but the back -to -back connection needs The quality of the image, especially if the back -to -back connection, has a greater impact on the quality of the image.

According to the above situation, the OTSYSTEEMS node light -end machine is used to achieve remote signal transmission; the pavement monitoring system needs to be connected to the camera controlled by the gimbal control. Data signal, meteorological monitor data signal. If it is a tunnel, the number of short-distance tunnels is not a lot. A link can be transmitted to the center with a link. Long-distance tunnels can be transmitted. We can divide 6-8 cameras into one group to concentrate or transmit videos.

Fully solve the problem of video transmission of the Road Management Sub -Center. The core idea of this solution is that the entire system structure is link type. It is referring to a core fiber inserted into multiple nodes and multiple transmitters on the same fiber. There is only one connecting machine in the center. Real -time transmission, but during the entire transmission process, the video is only digitized once, and all nodes are performed in the digital domain. It ensures that the video quality is exactly the same as the digital non -compressed point -to -point transmission. Real -time feedback.
