The utility model can further be specially:
Also include GIS-Geographic Information System and graphically indicate software, GIS-Geographic Information System is connected with the comparison process device, graphically indicates software and is installed in the comparison process device.
When the comparison process device detects unusual optical cable, then can carry out graphical analyzing and processing to the fault point, and finally in the display system of central processing unit, demonstrate the route of optical cable and the position of fault point according to the address code and the GIS-Geographic Information System of Monitor Sub-Station of Less.
Also include the optical cable business device, its fault warning output is connected with the comparison process device of central processing unit.
Central processing unit is on the basis that the loop cycle test is provided, can further provide based on transmitting warning and start test optical fibre cables: each optical cable business device and central processing unit are realized the communication transmission, owing to carried a large amount of business devices on the optical cable, after these business devices problems such as interruption or deterioration occur at optical cable, tend to produce specific warnings, for example for transmission network, the device port that interruption of optical cables can cause being connected with this root optical cable produces relevant alarm.As long as the corresponding relation of business device port and optical cable is known in definition aspect software, can be that fault has taken place which section optical cable just by alarm originating port number and veneer perception, central processing unit is after receiving warning information, send control unit to by data output device, trigger and start optical time domain reflectometer this optical cable is monitored.
Also include client, it is connected with the comparison process device.
Client its objective is to allow the user of system can effectively manage and monitor required cable resource as the man-machine interactive platform in the optical cable monitoring system.Client can be selected the optical cable that will test as required, directly control unit is assigned test instruction by central processing unit, optical time domain reflectometer is specified light path through driving monitoring, and test data is fed back to central processing unit, sends corresponding client to by central processing unit.This is a kind of roll-call test, can be used as replenishing of loop cycle test.
In sum, the utility model advantage compared to existing technology is, optical cable monitoring system has adopted the mode of central centralized control, processing that the optical cable in the zone is monitored, can in time scent a hidden danger, accomplish to become the passive active maintenance that is maintained as, shorten preventive maintenance time, alleviated attendant's pressure, improved the optical cable reliability of operation.Simultaneously combining geographic information system, optical cable business device, the geography information auxiliary monitoring is provided and starts testing scheme based on the alarm of transmitting, further reached time of shortening the trouble-shooting optical cable, really become the passive technique effect that is maintained as active maintenance, improved reliability and real-time fiber optic cable monitor.
