Referring to fig. 1, an optical fiber ring network intelligent identification system according to an embodiment of the present invention includes: the communication equipment 100 is used as a power optical fiber ring network communication equipment master station and can output communication light waves; a monitoring station 200 for outputting a monitoring light wave and receiving a return light wave reflected by the fiber code 470 to identify the fiber code 470; the first wavelength division multiplexer 300 is respectively connected with the communication equipment 100 and the monitoring station 200 and used for coupling and isolating the communication light wave and the monitoring light wave; a plurality of sequentially connected fiber identification distribution modules 400, each of the fiber identification distribution modules 400 includes a second wavelength division multiplexer 410, a third wavelength division multiplexer 420, a first adapter 430, a second adapter 440, a third adapter 450, a fourth adapter 460, and the fiber code 470, the fourth adapter 460, the third wavelength division multiplexer 420, the second wavelength division multiplexer 410, and the first adapter 430 are sequentially connected through an optical fiber, the first adapter 430 of a first one of the fiber identification distribution modules 400 is connected to the first wavelength division multiplexer 300 through an optical fiber, and the fiber code 470 is disposed on an optical fiber between the fourth adapter 460 and the third wavelength division multiplexer 420; and a plurality of industrial switches 500 connected with the fiber identification and distribution modules 400 in a one-to-one correspondence manner, wherein light receiving optical ports of the industrial switches 500 are connected with the second adapter 440, light emitting optical ports are connected with the third adapter 450, and the industrial switches are connected with the ring main unit 600 to realize data transmission and interaction.
The working process of this embodiment is that the communication device 100 and the monitoring station 200 respectively send the communication light wave and the monitoring light wave to the first wavelength division multiplexer 300 for coupling and isolation, the coupled light wave is sent into the optical fiber identification distribution module 400 through the optical fiber, and first passes through the first adapter 430 to the second wavelength division multiplexer 410, the second wavelength division multiplexer 410 separates the communication light wave and then sends the separated communication light wave to the industrial switch 500 through the second adapter 440, the industrial switch 500 analyzes the communication light wave and then connects with the ring main unit 600 to realize data transmission and interaction, and sends the communication light wave to the third wavelength division multiplexer 420 through the third adapter 450, and then the communication light wave is output to the optical fiber identification distribution module 400 of the next node through the fourth adapter 460; meanwhile, the second wavelength division multiplexer 410 outputs the separated monitoring light wave to the optical fiber code 470 through the third wavelength division multiplexer 420, the optical fiber code 470 reflects the light wave with the corresponding wavelength and is collected and identified through the monitoring station 200, the optical fiber code information collected by the monitoring station 200 comprises the corresponding wavelength and energy, the optical fiber code element wavelength is combined into a unique identification unit, the optical fiber link logical relationship of the optical fiber ring network is identified, the intelligent management of the optical fiber ring network is realized, and the management efficiency of the optical fiber ring network is improved; meanwhile, the operation state of each section of the optical fiber ring network is judged by utilizing the energy change collected by the optical fiber ring network, and the optical fiber section in the optical fiber ring network where the break point is located and the position in the optical fiber section are calculated under the fault condition.
Because the existing optical fiber ring network adopts section-by-section optical fiber communication, the optical fiber network structure is relatively more complex, the interference of optical fiber code identification caused by the isolation and coupling of wave bands is larger, and the optical fiber code identification is carried out by a more accurate monitoring station technology. As described above, in this embodiment, by setting the plurality of optical fiber identification distribution modules and the industrial switch in the chain structure, each optical fiber identification distribution module includes one input and one output wavelength division multiplexers and uniquely identifiable optical fiber codes, and while data transmission and interaction with the ring main unit are ensured, the monitoring station can realize information acquisition, segment management, segment monitoring and fault location calculation of the optical fiber codes by monitoring the optical waves and receiving the return optical waves reflected by the optical fiber codes.
In some embodiments of the present invention, the isolation of the first wavelength division multiplexer 300, the second wavelength division multiplexer 410, and the third wavelength division multiplexer 420 is greater than 30dB, which can prevent interference between the communication optical wave and the monitoring optical wave.
Since the existing ring network communication equipment and industrial switches basically use 1550nm, 1310nm and 1490nm optical fiber communication lightwaves, according to some embodiments of the present invention, the monitoring lightwaves output by the monitoring station 200 are other lightwaves except for 1550nm, 1310nm and 1490nm bands, so as to implement orthogonality between the communication lightwaves and the monitoring lightwaves.
Similarly, in some embodiments of the present invention, the backward light wave reflected by the fiber code 470 is other light waves outside the 1550nm, 1310nm and 1490nm bands.
In some embodiments of the present invention, the optical fiber code 470 is a plurality of optical fiber code elements with different central wavelengths, different reflectivities, and different distances coupled to the optical fiber, and serves as a unique identification unit, so that the monitoring station 200 can identify the logical relationship of the optical fiber links of the optical fiber ring network, thereby implementing intelligent management of the optical fiber ring network and improving management efficiency of the optical fiber ring network; meanwhile, the operation state of each section of the optical fiber ring network is judged by utilizing the energy change collected by the optical fiber ring network, and the optical fiber section in the optical fiber ring network where the break point is located and the position in the optical fiber section are calculated under the fault condition.
