Embodiment 1

[0034] The network structure of the present invention such as figure 1 As shown, it includes application layer 1, network layer 2 and terminal layer, wherein the terminal layer includes master RTU3 and slave RTU4. The network layer 2 forms a communication network through optical modems and optical fibers, and is set between the application layer 1 and the master RTU3, and between the master RTU3 layer and the slave RTU4, and is used for data communication between different network layers.

[0035] Application layer 1 includes the MTC master station located in the monitoring center of the power company. The MTC master station includes the master server, monitoring screen, alarm workstation, printer and networking communication unit, the master server, monitoring screen, alarm workstation, printer and group The network communication unit performs data communication with the network layer 2 through the industrial Ethernet communication port. The master station server includes a ...

Embodiment 2

[0042] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the remote optical fiber monitoring device further includes a data display unit 10 . The signal input end of the data display unit 10 is electrically connected to the output end of the monitoring module 5, and the data display unit 10 can display the operating status information of the optical fiber core of the optical cable collected by the monitoring module 5 on the spot, so that maintenance personnel can intuitively observe the state of the optical fiber. run information.

Embodiment 3

[0044] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 2 is that the remote optical fiber monitoring device also includes an alarm unit 11, and the alarm unit 11 adopts a rotary sound and light alarm. In case of abnormality, the rotary sound and light alarm will send out sound and light alarm to warn the workers.

Abstract

The invention discloses an optical cable fiber core network monitoring system, which includes an application layer, network layers and a terminal layer. The terminal layer comprises main RTUs and sub RTUs. The network layers constitute a communication network with an optical fiber through an optical modem, are disposed between the application layer and the main RTUs and between the main RTUs and the sub RTUs respectively, and are used for data communication among the different network layers. The main RTUs and the sub RTUs each include a far-end optical fiber monitoring device disposed in a communication machine room of a substation and composed of a monitoring module, an OTDR test module and a host computer. The invention is capable of remotely and automatically monitoring the entire optical cable line online, monitoring the variation and variation trend of optical fiber properties in real time, discovering faults, giving out a timely alarm, effectively reducing and preventing optical fiber faults, accurately determining the fault location of an optical cable, compressing the fault duration, reducing the workload of maintenance staff, and improving the work efficiency.

Description

technical field [0001] The invention relates to the field of electric power communication, in particular to an optical cable fiber core network monitoring system. Background technique [0002] With the development of modern network technology, optical fiber has become the main transmission medium. At present, the scale and quantity of optical cable construction in power system communication network and information system are already very large. In addition to abundant detours, it also puts forward high requirements for the operation and maintenance of communication optical cables. The transmission performance of the optical cable has changed to varying degrees from the time it was put into operation due to the environment and other conditions in the erection area. Routine detection of optical cables in the area, and a comprehensive grasp of their operating status is a necessary means to determine whether to carry out planned maintenance on optical cables, improve the operat...
