Description

Technical Field

[0001] The present invention relates to the technical field of emergency communications, and in particular to a communication emergency dispatch device. Background Art

[0002] In the event of an unexpected / planned optical cable interruption (such as municipal construction, pipeline collapse, typhoon, earthquake, geological disasters, etc.), a pigtail failure, or a planned optical cable maintenance (such as optical cable relocation, business cutover, etc.), the communication optical path service will be interrupted and some communication lifelines need to be restored as soon as possible.

[0003] In the related art, when an optical cable or pigtail fails, the emergency repair personnel first need to understand the wiring diagram of the computer room in detail or manually check one by one to determine the specific location of the fault; then, in the case of accidental or planned interruption of the optical cable, it is necessary to use jumpers between cabinets (ODF racks) to make temporary connections (withdraw the pigtail from the interrupted optical cable and jump directly to the emergency optical cable) to transfer the business on the faulty optical cable to the spare or emergency optical cable. In the case of pigtail failure, the emergency repair personnel re-lay the pigtail or use a temporary pigtail for jumpering to quickly restore the business; then the emergency repair personnel use hot melting (using a fusion splicer to fuse the ends of the optical fibers together) or cold connection (using an adapter or connector to connect the optical fibers) to achieve permanent or temporary connection between the optical cables; after completing the optical path jumper or pigtail restoration, business verification is required to ensure that all restored optical path businesses are operating normally, without new faults or accidental contact with other businesses; after the optical cable fault is repaired or the business cutover is completed, the emergency repair personnel also need to restore the temporarily jumped optical cable and pigtail to their original state.

[0004] However, when an optical cable fails, a planned maintenance or a pigtail fails, the temporary optical path recovery method in the related art uses a temporary connection jumper. In actual operation, there are many services in the computer room, a large number of jumpers, and the routing of the jumpers is disordered. When unplugging the interrupted optical fiber or jumper, it is easy to pull the wrong one, resulting in other business interruptions. The temporary optical path recovery method in the related art is inefficient. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In traditional optical path restoration, it is necessary to use fiber jumpers to make temporary connections between ODF racks or cabinets, especially when the fault occurs in a non-redundant optical cable segment (this segment of optical cable is the only path connecting two points, and the only way to restore communication is often temporary scheduling, such as using fiber jumpers to reconnect to other available optical cables, or urgently laying new optical cables until the original optical cable is repaired or the replacement line is built to complete the fault. Multiple physical connection adjustments are required during the recovery process). It may be necessary to jumper between multiple points, resulting in chaotic on-site wiring, increasing the difficulty of identification and operation, and may also accidentally touch or damage other normally operating pigtails during the recovery process, causing secondary interruption.

[0033] like Figures 1 to 6 As shown, an embodiment of the present invention provides a communication emergency dispatch device, which includes an emergency optical cable 10, two quick connectors 20, two connectors 30 and two pigtail bundles 40. The emergency optical cable 10 includes at least two emergency optical fibers. The two quick connectors 20 are respectively arranged at both ends of the emergency optical cable 10. The connector 30 has an optical cable interface 31 and at least two pigtail interfaces 32. The two quick connectors 20 can be connected to the optical cable interfaces 31 of the two connectors 30 respectively. The optical cable interface 31 has at least two optical cable contacts 311 connected to the at least two emergency optical fibers one by one. The at least two pigtail interfaces 32 are connected to the at least two optical cable contacts 311 in a one-to-one correspondence. The two pigtail bundles 40 are respectively arranged corresponding to the two connectors 30. The pigtail bundle 40 includes at least two pigtail cores. The at least two pigtail cores are arranged in a one-to-one correspondence with the at least two pigtail interfaces 32 of the connector 30. One end of the pigtail core is connected to the pigtail interface 32, and the other end of the pigtail core is provided with a dispatching connector.

[0034] The communication emergency dispatch device provided in this embodiment is applied, and the communication emergency dispatch device includes an emergency optical cable 10, two quick connectors 20, two connectors 30 and two pigtail bundles 40. When a temporary connection is made between two cabinets 70, at least two connectors 71 of the first cabinet 70 are respectively connected to the dispatch connectors of at least two pigtail cores of the first pigtail bundle 40, so that the signals of the at least two connectors 71 are aggregated to the first connector 30. Two quick connectors 20 are respectively arranged at both ends of the emergency optical cable 10, and the two quick connectors 20 are respectively connected to the optical cable interfaces 31 of the two connectors 30, so that the first connector 30 transmits the signal to the second connector 30 through the emergency optical cable 10, and the second connector 30 distributes the signal to at least two pigtail cores of the second pigtail bundle 40, and at least two dispatch connectors of the second pigtail bundle 40 are connected to at least two connectors 71 of the second cabinet 70, so that the fiber adjustment work is systematically performed according to the actual needs in the emergency dispatch process. Therefore, the communication emergency dispatch device is used instead of the fiber jumper in the prior art to temporarily restore the optical path, which simplifies the deployment work. Without changing the original optical path wiring, a new optical path connection can be quickly established. That is, by flexibly deploying the communication emergency dispatch device between cabinets or inside the computer room, instead of directly performing a large number of fiber jumper operations on the ODF rack or equipment, the business can be quickly restored, avoiding the previous complicated operations such as on-site emergency repair and brazing, reducing on-site emergency repair conditions, improving the cleanliness of the room or cabinet during emergency wiring, reducing operating risks, and improving operating efficiency.

[0035] In this embodiment, at least two emergency optical fibers of the emergency optical cable 10 are bundled together through a leather bag. The number of emergency optical fibers and the specifications of the emergency optical cable are selected according to actual use needs.

The use of the at least two photoelectric conversion components can directly convert optical signals into electrical signals, providing more flexible scheduling options for the site.

[0038] like Figures 1 to 4 As shown, the at least two transmission members 34 also include at least two connecting optical fibers, one end of the at least two connecting optical fibers is respectively connected to the at least two optical cable contacts 311, and the other end of the at least two connecting optical fibers is respectively connected to the at least two pigtail interfaces 32. By using the at least two connecting optical fibers, jumpering between optical paths can be quickly achieved.

By adopting the above-mentioned housing 33, when connecting the pigtail interfaces 32, it is convenient to distinguish the pigtail interfaces 32 connected to the electrical signal connection end and the pigtail interfaces 32 connected to the connecting optical fiber, so as to facilitate quick docking.

[0040] In this embodiment, the housing 33 is made of electromagnetic shielding material. The housing 33 described above can prevent external signals from interfering with signal transmission of the transmission member 34 disposed in the housing 33 .

[0042] In this embodiment, the magnetic fixing portion 35 comprises a magnetic sticker, which has the advantages of low cost, simple structure and easy installation, and the magnetic sticker is bonded to the housing 33 .

[0043] like Figures 1 to 4As shown, the communication emergency dispatch device also includes an optical cable reel 50, which includes a protective shell 51 and a winding member 52. The protective shell 51 has two wire-retracting holes, and the two ends of the emergency optical cable 10 extend out of the protective shell 51 from the two wire-retracting holes respectively. The winding member 52 is rotatably arranged in the protective shell 51, and the middle part of the emergency optical cable 10 is wound on the winding member 52. The optical cable reel 50 with the above structure is used to wind the middle part of the emergency optical cable 10 on the winding member 52, and the protective shell 51 is used to protect the winding member 52 and the wound emergency optical cable 10. The winding member 52 is rotated to quickly release and recycle the emergency optical cable 10, avoiding the complicated process of manually pulling and arranging the optical cable in the traditional way, thereby improving the efficiency of emergency dispatch.

The magnetically attracted fixing portion 35 of the connector 30 can be magnetically attracted to the alloy shell to temporarily fix the connector 30, thereby preventing the connector 30 from shaking, bumping, or being damaged during transportation, and facilitating carrying and on-site operation. In addition, the magnetically isolating inner shell is used to prevent the signal transmission of the emergency optical cable 10 wound in the protective shell 51 from being interfered with by external signals and the magnetic attraction cooperation between the magnetically attracted fixing portion 35 and the alloy shell.

[0045] In this embodiment, the alloy shell is made of iron-aluminum alloy.

[0046] like Figures 1 to 4 As shown, the optical cable winding member 50 further includes two storage barrels 53, which are respectively arranged outside the two wire-receiving and releasing holes, and protrude outward from the alloy shell. The two quick connectors 20 are respectively in contact with the ends of the two storage barrels 53 that are away from the alloy shell, so that the operator can conveniently take the quick connector 20 to pull out the emergency optical cable 10 wound by the optical cable winding member 50.
