When identifying on-site, first take a picture of the paper label on the fiber routing port connector on the smart terminal (fiber optic full data detector, mobile phone, Pad, etc.), and select and process the picture of the paper label. Finally, The graphic format processed on the smart terminal is uploaded to the cloud server after adding the address information (including but not limited to GPS address information).

The invention can be applied to the following multiple scenarios:

1. Establishing the file of the new computer room: In the new computer room, the construction staff inserts the connector into the required optical port according to the requirements, and records the business of the connector by inserting the name of the computer room, the cabinet number, the frame number, and the rows and columns. Type, optical path code, opposite optical port position, length, and input to form a paper label; take a photo of the paper label, and then take the photo of the paper label and the above optical port information, together with the fiber line loss at the optical port, and the optical fiber connection The end-face loss of points, as well as personnel information and time information are realized in the APP;

2. The electronic files of the organic room (electronic paper label): the construction personnel take photos of the existing paper labels, attach GPS location information, the system according to the computer room address, computer room name, cabinet name number, frame number, The rows and columns form a system code for searching. The photos of the paper label are uploaded to the server after being automatically corrected and enhanced and sharpened by the mobile phone APP for identification and query use.

3. When the optical port is located and searched, the construction personnel activates the optical port coding through the APP, and the activation information is emitted through the cloud server to instruct the optical port locator installed in the computer room and cabinet where the optical port is located, prompting the site construction staff to find the corresponding cabinet. , Find the connector on the corresponding optical port according to the coordinates of the optical port prompted by the APP, or display the position of the optical port through the prompt lamp connected to each optical port through the optical port locator, and connect the paper label bundled on the connector with the APP Compare the paper label in the optical port information downloaded from above.

Retrieve and find the associated information of the wrong optical port, query historical records and correct the routing information, and finally calibrate the optical port information to finally achieve the consistency of the field information and the cloud server information, which can effectively improve work efficiency and correct errors;

4. Realize big data management after the files of the organic room have been electronicized: The electronic information of the paper labels of the organic room is used to connect all the relevant paper label information together through the optical path coding and business type to form a routing circuit diagram. Or it is determined by the peer information that it is a line, that is, the same route;

5. When the optical port of the connector is faulty, the photo paper label is taken and the complete information is downloaded from the server to confirm the position of the optical port, so that the fault can be quickly removed;

6. Confirmation of discarded optical fiber connectors: Some unused connectors in the equipment room are not cleaned in time after being pulled out, or connectors that have no service are still inserted in the optical port, and the upstream optical fiber connectors have been pulled out. The connection, the construction staff is afraid to determine whether it is in use, resulting in waste of resources. At this time, you can take a photo of the paper label, download the entire optical port connector information and routing information, and finally determine whether to discard the optical fiber connector;

7.

8. Paper label replaces electronic label: electronic label has three functions, one is information recording, the second is optical port positioning, and the third is wrong insertion alarm. Through the automatic identification of the paper label of the present invention, the first two can be realized. This function is redundant, and the third incorrect alarm is a redundant function, because the line conditions at the construction site are different from the design content of the drawing. The construction site can adjust which optical port the connector is inserted into. If the optical port has poor connection conditions, It is extremely normal to replace the optical port. The criterion is whether the business is open. The construction staff will eventually write the correct information on the paper label, and upload the information by taking pictures to ensure that the field information is consistent with the server information and work efficiently. In the prior art, the electronic tag was incorrectly inserted into the alarm, and the on-site construction staff was required to notify the background staff to re-issue the work order and change the work order according to the optical port on the scene, which is inefficient;

9. The role of photon labels in the automatic identification system of paper labels: When some old computer room paper labels are lost or wrong, the photon label routing search is used to find the exact route and optical port connector information, and finally a new paper label is formed.
