Stating wire transmission unit includes forming the multiple switch and netting twine of wired connection.
The wireless transmission unit also includes wireless router.
The wireless router includes being used for the wireless router and 100,000,000 routers for installing wireless Internet card.
The beneficial effects of the utility model are:On the one hand, the networking of live video monitoring is carried out using wireless bridge, can be with
Save it is a large amount of build and maintenance cost, it is and mobile flexible, can quickly meet video monitoring system to image and data transfer
Demand, to realize that the digitlization of chimney anticorrosion engineering video monitoring and networking provide wireless bridge;On the other hand, nothing is utilized
Gauze bridge connects two cable LANs of project management department and power plant, realizes the seamless combination of wireless network and cable network,
Both the purpose of project management department's online had been reached, and had saved cost again, also facilitated power plant and job site video monitoring is shared, enter
One step improves engineering management and control ability.
