At a new optical fiber connection；
3), after the completion of two new optical fiber connections, by Network Video Surveillance equipment M and Network Video Surveillance equipment M+2
It is deleted from the topology of platform；
4), after equipment is re-energised normal work, two new optical fiber connections can be broken into original by respective photoswitch
The 4 optical fiber connection come, and Network Video Surveillance equipment M and Network Video Surveillance equipment M+2 are rejoined into platform topology.
The beneficial effects of the invention are as follows：The system that this method can ensure Network Video Surveillance equipment composition, no matter it encounters
Network Video Surveillance device powers down or optical fiber connection power-off, can utilize the ring of the power-off protection function and network of photoswitch
Defencive function realizes the duplicate protection in network video monitor and control system.
When the Network Video Surveillance equipment in network video monitor and control system when something goes wrong, pass through the previous section of the equipment
Point device can be completed using photoswitch with the latter node device and connect.No matter encountering Network Video Surveillance device powers down still
Optical fiber connection power-off, the phenomenon that being not in equipment normal work and can not communicate.This method can realize Network Video Surveillance
The duplicate protection of equipment, safety higher are easy to implement.
