DETAILED DESCRIPTION

[0020] The utility model will be described in detail in combination with the drawings.

[0021] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0022] The application provides a kind of based on radio frequency identification's optical cross-box asset management device, which includes:

[0023] At least one sub-control board 1, which is provided with RFID read-write unit 11 corresponding to each port of fiber flange plate 5.

[0024] Mounting piece is used to install each sub-control board 1 to the port position of corresponding fiber flange plate 5 respectively, and mounting piece limits each RFID read-write unit 11 in the corresponding port position by mechanical limiting structure.It needs to be explained that the port position corresponding to RFID read-write unit 11 is not necessarily aligned with the port, but is aligned with the RFID tag connected to the tail fiber 6 to be connected to the port (usually connected to the tail fiber 6 connected to the port through fiber adapter 62) to ensure good reading effect.

[0025] Main control board 2 is connected with each sub-control board 1 respectively; main control board 2 is provided with communication module 21.

[0026] Usually, for optical cross-box, it contains multiple fiber flange plates 5, and multiple ports are provided side by side on each fiber flange plate 5, that is, multiple tail fibers 6 can be connected on one fiber flange plate 5.Therefore, the optical cross-box asset management device usually includes multiple sub-control boards 1, and one sub-control board 1 is installed to the port position of one fiber flange plate 5 by mounting piece. Figure 1 As shown in the figure, RFID read-write unit 11 on sub-control board 1 is used to identify the RFID tag on the tail fiber connected to the corresponding port position to read and write port information.

[0027] Mounting piece connects sub-control board 1 to the port position of fiber flange plate 5, and also limits the movement of RFID read-write unit 11, so that each RFID read-write unit 11 is aligned with the RFID tag on the tail fiber 6 corresponding to the port and keeps stable state, which ensures good reading effect and prevents string reading or missing reading.As an optional implementation, mounting piece installs sub-control board 1 through detachable structure, so that sub-control board 1 can be directly installed on existing fiber flange plate 5, without replacing existing fiber flange plate 5 and other facilities.

[0028] The main control board 2 is responsible for data collection, reporting, and receiving and executing upper-level instructions, so the main control board 2 must have a main control unit. The received pairing information is reported through the communication module 21, or the instructions for updating port information issued by the upper level are received through the communication module 21. Since each port is provided with an RFID read-write unit 11, the pairing and state monitoring of the port and the connected optical fiber 6 can be realized without human intervention. Each RFID read-write unit 11 operates in parallel, and the asset management efficiency is high.

[0029] As an optional embodiment, when the number of sub-control boards 1 is two or more, each sub-control board 1 is connected in turn and then connected to the main control board 2. As shown in Figure 1 The connection port 12 is provided on the sub-control board 1, and when the number of sub-control boards 1 reaches two, the connection port 12 of the next layer of sub-control board 1 is connected to the connection port 12 of the previous layer of sub-control board 1, and the connection port 12 of the uppermost layer of sub-control board 1 is connected to the main control board 2. In this way, the wiring can be connected conveniently, and the situation of messy wiring can be avoided.

[0030] As an optional embodiment, the connection part of each sub-control board 1 to other sub-control boards 1 or the main control board 2 is located on the same side. The connection part of the sub-control board 1 to the outside is the connection port 12, Figure 2 As shown in the figure, the connection ports 12 of all sub-control boards 1 are located on the right side of the sub-control board 1, so that the wiring between the sub-control boards 1 can be shortened as much as possible. Preferably, the main control board 2 is also arranged on this side.

[0031] As an optional embodiment, the sub-control boards 1 and the main control board 2 are connected through Type-C data lines 3 to realize reliable and stable data transmission.

[0032] As an optional embodiment, as shown in Figure 3 The mounting member connects the sub-control board 1 to the left and right side walls of the optical fiber flange 5. Since the port is located on the front side of the optical fiber flange 5, the sub-control board 1 is also located on the front side of the optical fiber flange 5. Therefore, the gravity of the sub-control board 1 borne by the connecting member is transmitted to the optical fiber flange 5 and does not exert a normal force on the left side wall 51 and the right side wall 52, so that deformation is not caused.

[0033] As an optional embodiment, as shown in Figure 3As shown, the mounting component includes a first mounting part 41 and a second mounting part 42. The first mounting part 41 is connected to the left end of the sub-control plate 1 and restricts the sub-control plate 1 from moving to the left by a first limiting structure. The first mounting part 41 is also connected to the right end of the sub-control plate 1 and restricts the sub-control plate 1 from moving to the right by a second limiting structure. Designing the mounting component as separate parts with the first mounting part 41 and the second mounting part 42 improves assembly flexibility and portability. The first limiting structure can be a vertically protruding structure on the first mounting part 41; similarly, the second limiting structure can be a vertically protruding structure on the second mounting part 42. The two protruding structures respectively restrict the movement of the sub-control plate 1 in the left and right directions.

[0034] As an optional implementation, both the first mounting component 41 and the second mounting component 42 include a fixing component 43, which is used to insert into the gap between the cover plate 53 of the fiber optic flange 5 and the left and right side walls, and to cover the top of the left and right side walls.

[0035] Taking the first mounting component 41 as an example, such as Figure 4 As shown, the fixing component 43 on the first mounting component 41 is U-shaped and is inserted from above into the top of the left side wall 51 of the fiber optic flange 5 to achieve a fixed connection. The fixing component 43 can be designed as a flexible structure to clamp the left side wall 51 after being inserted into the top of the left side wall 51, or it can be designed with a raised edge (not shown) at the bottom of the fixing component 43 on the side of the cover plate 53 of the fiber optic flange 5 to lock the fixing component 43 in place by the cover plate 53.

[0036] As an optional implementation, the communication module 21 is a communication circuit that supports wired and / or wireless communication to enable data interaction with a remote host computer or with field devices.

[0037] like Figure 5 As shown, communication module 21 can support wireless communication functions such as cellular mobile communication or IoT communication, and interact with the cloud 9 through wireless gateway 7. Alternatively, communication module 21 can support short-to-medium range wireless communication functions such as ZigBee, LoRa, and Bluetooth, and interact with handheld terminals 8 such as PDAs and tablets on site. Alternatively, communication module 21 can support wired communication functions such as OTG (On The Go), and interact with handheld terminals 8 through OTG cables.

[0038] This application embodiment also provides a radio frequency identification (RFID)-based optical distribution box asset management system, which includes an RFID-based optical distribution box asset management device as described in the above embodiment, and at least one optical fiber adapter 62. The optical fiber adapter 62 is provided with (embedded or pasted on the surface) an RFID tag, and the optical fiber adapter 62 is used to connect to the corresponding pigtail 6.

[0039] An optical fiber adapter 62 needs to be connected to each of the pigtail 6, and the RFID tag on the optical fiber adapter 62 is written with the port information. The RFID read-write unit 11 reads the RFID tag on the pigtail connected to the corresponding port to obtain the port information, thus realizing the pairing of the port and the pigtail.

[0040] The optical fiber adapter 62 is connected to the optical fiber joint 61 of the pigtail as much as possible to be as close as possible to the RFID read-write unit 11 to improve the radio frequency identification accuracy. As shown in FIG. 2, as an optional embodiment, the structure of the optical fiber adapter 62 is adapted to the optical fiber joint 61 of the pigtail. For example, for the FC type optical fiber joint 61, the optical fiber adapter 62 is designed to have a circular inner cavity to be sleeved on the optical fiber joint 61, and for the ST type optical fiber joint 61, the optical fiber adapter 62 is designed to have a square inner cavity to be sleeved on the optical fiber joint 61, or the inner cavity of the optical fiber adapter 62 can be designed to be compatible with the FC type and ST type optical fiber joint 61.
