Description

Technical Field

[0001] The invention belongs to the technical field of optical cable equipment and relates to an intelligent optical cross-connection box monitoring and management method and system. Background Art

[0002] With the rapid development of China's economy, Internet construction has been popularized in urban households, rural towns, and some rural households, and users have more and more actual needs, such as: videophone, digital TV, network, etc. The telecommunications industry is constantly developing, and the large-scale implementation of optical fiber replacement has greatly increased the use of optical fiber.

[0003] In the prior art, the optoelectronic integrated cable generally includes: a reinforcing core, a cable core composed of an optical cable, a group of power cords and a filling rope body twisted on the reinforcing core, a wrapping tape layer wrapped around the cable core, and an outer sheath; the more commonly used optoelectronic integrated cable is an optical cable with a bundle tube and a copper conductor wire twisted together to achieve simultaneous transmission of optical fiber signals and electrical energy. The fiber core in the optical cable often adopts a one-main-one-backup structure. For example, patent CN202010014470.9 discloses a central-end device of a wavelength division multiplexing system, which uses an optical switch to connect a main optical fiber and a backup optical fiber to achieve fiber core switching in the event of a fault, but it only communicates one way, resulting in low utilization of fiber core resources. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent optical cross-connection box monitoring and management method and system, increase the utilization rate of fiber core resources, and realize the fiber core usage status monitoring and spare fiber core switching functions.

[0005] In order to achieve the above object, the basic scheme of the present invention is: a monitoring and management method of an intelligent optical cross-connection box, including the following schemes:

[0006] Solution 1:

[0007] The fiber cores of each incoming optical cable are grouped into N cores, of which N-1 cores are main fiber cores, 1 core is a spare fiber core, and N is a positive integer greater than or equal to 2;

[0008] Each main fiber core of the incoming optical cable is connected to the main fiber core of the outgoing optical cable through a switch pair consisting of a 2 / 1-gated optical switch and a 1 / 2-gated optical switch; the spare fiber core of the incoming optical cable is connected to a 1 / N-gated optical switch, and the N output ends of the 1 / N-gated optical switch are respectively connected to the other input end of the 2 / 1-gated optical switch corresponding to the main fiber core; one output end of the 1 / 2-gated optical switch at the outgoing end of each main fiber core is connected to the N / 1-gated optical switch; one output end of the 1 / N-gated optical switch of the spare fiber core is directly connected to one input end of the N / 1-gated optical switch;

[0009] The control ends of the 2 / 1 gated optical switch, the 1 / 2 gated optical switch, the 1 / N gated optical switch and the N / 1 gated optical switch are all connected to the MCU, and the MCU monitors the connection status and usage status of each incoming optical cable core and outgoing optical cable core of the optical cross-connection box; when one of the main optical cores of the outgoing optical cable fails, it can be switched to the spare outgoing optical core channel for use;

[0010] Option 2:

[0011] The fiber cores of each incoming optical cable are grouped into N cores, and the N cores are all main fiber cores;

[0012] Fiber cores 1 to N are connected to the corresponding fiber cores of outgoing optical cables through control switches, and the control switches are connected to the MCU. The MCU monitors the on / off status and usage status of each incoming optical cable core and outgoing optical cable core of the optical cross-connection box.

[0013] The working principle and beneficial effect of this basic solution are: this technical solution treats the fiber cores of each incoming optical cable as a group of any N cores, with N-1 cores used as the main core and 1 core as the spare core, achieving a 75% fiber core resource utilization rate, and realizing the fiber core usage status monitoring and spare core switching functions. Multiple N-core optical cable cores form multiple relatively independent microprocessing systems, and realize unified monitoring and management between multiple microprocessing systems.

[0014] The control ends of all the optical switches are connected to the MCU, which monitors the connection status and usage status of each incoming optical cable core and outgoing optical cable core; when one of the main optical cores of the outgoing optical cable fails, it can be switched to the spare outgoing optical core channel for use (for the next-level optical cross-connection box, it corresponds to the failure of the main optical core of a certain incoming optical cable, and it is switched to the spare optical core of the incoming optical cable). With this technical solution, N is a positive integer greater than 2. By adjusting the value of N, the utilization rate of the main optical core resources of the optical cross-connection box can be flexibly adjusted, which can realize both the monitoring of the core usage status and the switching function of the spare optical core.

[0015] Furthermore, in Plan 1, when one of the main fiber cores of the incoming optical cable fails, it is switched to the spare outgoing fiber core channel for use. At the same time, the corresponding spare fiber core of the incoming optical cable in the lower optical cross-connection box is switched and controlled to restore the main fiber core of the outgoing optical cable of the lower optical cross-connection box, thereby avoiding manual jumper operations between the local and lower optical cross-connection boxes.

[0016] This prevents manual jumper operation between the local and lower optical junction boxes, making it easier to use.

[0017] Furthermore, in solution 1, when one of the main fiber cores of the incoming optical cable fails,

[0018] If the fault is located at the fiber core input end of the optical cross-connection box, the connection channel of the 2 / 1 gated optical switch connected to the fiber core is controlled to be connected to the 1 / N gated optical switch;

[0019] If the fault is located at the fiber core output end of the optical cross-connection box, the connection channel of the 1 / 2-gated optical switch connected to the fiber core is controlled to be connected to the connection channel of the N / 1-gated optical switch;

[0020] If multiple optical cross-connection box sections corresponding to the main fiber core fail simultaneously, the 1 / N selection optical switch connected to the backup fiber core is controlled to be connected to the N / 1 selection optical switch;

[0021] In the case of tight fiber core resources, the spare fiber core switching function can be cancelled. By controlling the 1 / N selection optical switch connected to the spare fiber core to be connected with the N / 1 selection optical switch, direct connection between the spare input fiber core and the spare output fiber core of the optical cross-connection box can be achieved.

[0022] When the main fiber core fails, the backup fiber core can be switched according to the fault location.

[0023] Furthermore, the MCU is provided with an optical time domain transmitting unit to send short pulse signals to different main fiber cores and record the signals reflected from the main fiber cores at different times. The optical time domain transmitting unit converts the collected reflection signal data into a time domain image to display the attenuation of the optical fiber and the location of the fault.

[0024] The fiber core usage status is monitored by sending and receiving corresponding signals of the MCU.

[0025] Furthermore, when more than one main fiber core fails, the main fiber core with a large attenuation is switched to a backup optical fiber based on the attenuation of all the failed main fiber cores.

[0026] In case of a fault with large attenuation, the main fiber core is switched to the backup fiber to ensure greater utilization of the fiber core.

[0027] The present invention also provides an intelligent optical cross-connection box monitoring and management system, comprising a plurality of 2 / 1 gated optical switches, a plurality of 1 / 2 gated optical switches, a 1 / N gated optical switch, an N / 1 gated optical switch and an MCU;

[0028] Each incoming optical cable has N cores as a group, N-1 cores are the main cores, and 1 core is the spare core;

[0029] Each main fiber core of the incoming optical cable is connected to the main fiber core of the outgoing optical cable through a switch pair consisting of a 2 / 1-gated optical switch and a 1 / 2-gated optical switch; the spare fiber core of the incoming optical cable is connected to a 1 / N-gated optical switch, and the N output ends of the 1 / N-gated optical switch are respectively connected to the other input end of the 2 / 1-gated optical switch corresponding to the main fiber core; one output end of the 1 / 2-gated optical switch at the outgoing end of each main fiber core is connected to the N / 1-gated optical switch; one output end of the 1 / N-gated optical switch of the spare fiber core is directly connected to one input end of the N / 1-gated optical switch;

[0030] The control ends of the 2 / 1 gated optical switch, the 1 / 2 gated optical switch, the 1 / N gated optical switch and the N / 1 gated optical switch are all connected to the MCU, and the MCU executes the first solution of the method of the present invention to monitor and manage the optical cross-connection box.

[0031] The fiber cores of each incoming optical cable of this system are grouped into any N cores, with N-1 cores used as the main cores and 1 core used as a spare core, achieving a fiber core resource utilization rate of 75%, realizing the fiber core usage status monitoring and spare fiber core switching functions.

[0032] The present invention also provides an intelligent optical cross-connection box monitoring and management system, comprising a control switch and an MCU;
