[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] See also Figure 1 , Figure 1 : is a structural block diagram of an RFID reader provided in an embodiment of the present application, wherein the RFID reader comprises:

[0044] Antenna 1, used to receive the radio frequency signal sent by the RFID tag;

[0045] Camera module 2, used for taking images of ports;

[0046] Host 3, including a radio frequency module 31 and a main control module 32;

[0047] The radio frequency module 31 is used to transmit the radio frequency signal;

[0048] The main control module 32 is used to:

[0049] Receive and analyze the radio frequency signal transmitted by the radio frequency module 31 to obtain identification information of the RFID tag; the identification information of the RFID tag is used to identify the port;

[0050] Receive the port image transmitted by the camera module 2, or receive and send the port image transmitted by the camera module 2 to the resource management system.

[0051] It can be understood that the identification information of the RFID tag is read by bringing the antenna 1 of the RFID reader close to the RFID tag; specifically, the antenna 1 of the RFID reader sends a radio frequency signal of a specific frequency. When the antenna 1 of the RFID reader is close to the RFID tag, that is, the distance between the antenna 1 of the RFID reader and the RFID tag is less than a preset distance, the RFID tag is activated and sends a radio frequency signal of a specific frequency to the RFID reader. The antenna 1 of the RFID reader receives the radio frequency signal and transmits it to the main control module 32 through the radio frequency module 31. The main control module 32 parses the radio frequency signal to obtain the identification information of the RFID tag. Optionally, the identification information of the RFID tag is a manufacturer code (Target ID, TID), and the TID of each RFID tag is unique and cannot be changed.

[0052] The identification information of the RFID tag can be used to identify the port, that is, the identification information of the port is obtained according to the identification information of the RFID tag, so that the use status of the port, the connection relationship of the jumper fiber and other information can be managed through the identification information of the port. For example, the identification information of the RFID tag is directly used as the identification information of the port, specifically, the identification information of the RFID tag is sent to the resource management system, and the resource management system associates and binds the identification information of the RFID tag with the corresponding port, so that the use status of the port, the connection relationship of the jumper fiber and other information can be managed through the associated identification information.

[0053] At the same time, the port image is captured by the camera module 2 installed on the antenna 1 to understand the actual situation of the port, especially the occupancy of the ODF port, so as to ensure the real-time update of the port occupancy in the resource management system, so that the actual occupancy of the ODF port is consistent with the occupancy recorded by the resource management system.

[0054] It is worth noting that the embodiments of the present application are not limited to the identification of ODF ports. The ports to be identified can be other distributed and concentrated ports of dumb resources, such as PON (Passive Optical Network) ports, neatly arranged optical fibers in optical cables, network ports, etc., or integrated and distributed components with identification in logistics warehousing, or various distributed and concentrated ports or components of power grid systems. Examples are not given here one by one. For the sake of convenience, the ports to be identified are used for unified description.

[0055] Optionally, the camera module 2 is disposed on the antenna 1, which can further ensure that the port image is captured when the port is marked.

[0056] In an optional embodiment, the main control module 32 or the resource management system identifies the initial identification information of the port according to the received port image, so as to obtain the identification information of the port according to the initial identification information and the identification information of the RFID tag.

[0057] In the embodiment of the present application, the RFID reader or resource management system can perform one-to-one identification, that is, use one RFID tag to identify one port, or one-to-many identification, that is, use one RFID tag to identify multiple ports.

[0058] (1) Install an RFID tag on each port:

[0059] One-to-one identification: The RFID reader reads the identification information of the RFID tag and takes a photo of the port. The identification information of the read RFID tag is used as the identification information of the port, or the identification information of the RFID tag is spliced ​​with a preset character, and the splicing result is used as the identification information of the port. For example, a preset hexadecimal character "0" is spliced ​​at the end of the identification information of the RFID tag as the identification information of the port. The splicing can be performed at any position of the identification information of the RFID tag, and is not specifically limited here.

[0060] (2) Install one RFID tag for every N ports

[0061] One-to-many identification is adopted: the RFID reader reads the identification information of the RFID tag and takes a picture of the port to obtain a port image; then, the port image is identified to obtain the initial identification information of the port (for example, the serial number next to the ODF port), and the identification information of the port is obtained according to the identification information of the RFID tag and the initial identification information of the port, or the port image is sent to the resource management system, the resource management system identifies the port image to obtain the initial identification information of the port, and the identification information of the port is obtained according to the identification information of the RFID tag and the initial identification information of the port.

[0062] The identification information of the port is obtained according to the identification information of the RFID tag and the initial identification information of the port. Specifically, the identification information of the RFID tag and the initial identification information of the port are directly spliced ​​to obtain the identification information of the port; or the initial identification information of the port is converted into characters, such as hexadecimal characters, and then the identification information of the RFID tag and the characters are spliced ​​to obtain the identification information of the port. The splicing can be performed at any position of the identification information of the RFID tag, and is not specifically limited here.

[0063] When the initial identification information of the port is not recognized, the RFID reader will prompt the operator to retake the photo, or prompt the operator to manually enter the initial identification information until the requirements are met.

[0064] For example, the TID of the RFID tag of a certain ODF port is E20034120614141100734886 (24-bit hexadecimal), and the initial identification information of the ODF port is 2. Then, the initial identification information of the ODF port is spliced ​​at the end of the TID, and the identification information of the ODF port is obtained as follows: E200341206141411007348862. Since the TID of each RFID tag is unique, the identification information of the ODF port formed by splicing a different hexadecimal character at the end of the TID is still unique. In this way, each ODF port can also have a unique identification information. One RFID tag can form the identification information of up to 16 ODF ports, that is, it can identify up to 16 ODF ports.

[0065] This not only significantly reduces the number of RFID tags required to identify the same number of ports, for example, when one RFID tag is used to identify 12 ODF ports, the RFID tag and installation costs are only about 10% of the original solution, but also increases the spacing between RFID tags, reduces the difficulty of RFID tag installation, reduces signal interference between adjacent RFID tags, and improves the accuracy of RFID tag identification information collection.

[0066] In an optional embodiment, the main control module 32 identifies the occupancy status of the port based on the port image; or, receives and sends the port image taken by the camera module 2 to the resource management system, so that the resource management system identifies the occupancy status of the port based on the port image.

[0067] In the embodiment of the present application, the port image is also used to identify the occupancy of the port. After the main control module 32 obtains the port image, it can identify the occupancy of the port and send the occupancy to the resource management system; it can also directly send the port image to the resource management system, and the resource management system identifies the occupancy of the port image. When the embodiment of the present application uses an RFID reader to identify the port, the occupancy of the port is synchronized in real time, thereby ensuring the real-time update of the port occupancy in the resource management system, so that the actual occupancy of the port is consistent with the occupancy recorded by the resource management system.

[0068] In an optional embodiment, the antenna 1 is also provided with a pointed protrusion 4, the camera module 2 is arranged on the pointed protrusion 4, and the direction of the pointed protrusion 4 is used to point to the port; based on the direction of the host 3 toward the antenna 1, the optical axis direction of the camera module 2 is consistent with the direction of the pointed protrusion 4.

[0069] In the embodiment of the present application, a pointed protrusion 4 is further provided on the antenna 1, and the camera module 2 is provided on the pointed protrusion 4, the direction of the pointed protrusion 4 is used to point to the port, based on the direction of the host 3 toward the antenna 1, the optical axis direction of the camera module 2 is consistent with the direction of the pointed protrusion 4, that is, from the direction of the host 3 toward the antenna 1, the shooting direction of the camera module 2 is consistent with the direction of the pointed protrusion 4, so that when collecting the identification information of the port, the same port can be photographed, which not only makes it convenient for users to directly observe the identification and which port is photographed, but also realizes the identification information of the RFID tag of the same port while identifying the occupancy of the same port.

[0070] In an optional embodiment, a light source module 5 is further provided on the pointed protrusion 4; based on the direction of the host 3 toward the antenna 1, the light beam direction of the light source module 5, the optical axis direction of the camera module 2 and the direction of the pointed protrusion 4 are consistent.

[0071] In the embodiment of the present application, in order to more clearly observe which port is marked and photographed, a light source module 5 is further provided on the pointed protrusion 4. Based on the direction of the host 3 toward the antenna 1, that is, from the direction of the host 3 toward the antenna 1, the light beam direction of the light source module 5, the optical axis direction of the camera module 2 and the direction of the pointed protrusion 4 are consistent. By observing the irradiation position of the light beam of the light source module 5, it is possible to know which port is marked and photographed. The light source module 5 is preferably a red light source module, and the light beam is more obvious and easier to observe.

[0072] In an optional embodiment, the angle between the optical axis direction of the camera module 2 and the side of the antenna 1 provided with the pointed protrusion 4 is 30° to 45°; the angle between the installation direction of the light source module 5 and the side of the antenna 1 provided with the pointed protrusion 4 is 30° to 45°; the beam angle of the light source module 5 is 10° to 15°.

[0073] It should be noted that the angle α1 between the optical axis direction of the camera module 2 and the side of the antenna 1 provided with the pointed protrusion 4, the angle α2 between the installation direction of the light source module 5 and the side of the antenna 1 provided with the pointed protrusion 4, and the beam angle being too large or too small will affect the shooting position of the camera module 2 and the light beam irradiation position of the light source module 5. In the embodiment of the present application, the angle α1 is preferably 30° to 45°, the angle α2 is preferably 30° to 45°, and the beam angle is preferably 10° to 15°, so that the camera module 2 can more accurately capture the port and the light beam of the light source module 5 can more accurately point to the port, further ensuring that the light beam direction of the light source module 5, the optical axis direction of the camera module 2 and the direction of the pointed protrusion 4 are consistent.

[0074] For example, Figure 2-Figure 5 In order to facilitate the installation of the camera module 2 and the light source module 5 on the pointed protrusion 4, the camera module 2 and the light source module 5 are arranged on a side of the pointed protrusion 4 away from the host 3, and the side is inclined so that the angle α1 between the optical axis direction of the camera module 2 and the side of the antenna 1 provided with the pointed protrusion 4 is 30° to 45°, and the angle α2 between the installation direction of the light source module 5 and the side of the antenna 1 provided with the pointed protrusion 4 is 30° to 45°; the inclined surface The vertical direction is the optical axis direction of the camera module 2 and the installation direction of the light source module 5, that is, the angle between the inclined surface and the optical axis direction of the camera module 2 is 90°, and the angle between the inclined surface and the installation direction of the light source module 5 is 90°; then, the camera module 2 and the light source module 5 are both arranged on the side of the pointed protrusion 4 away from the host 3, and the angle between this side and the side of the antenna 1 provided with the pointed protrusion 4 is (90°+30°)~(90°+45°).

[0075] Specifically, the angle α1 and the angle α2 can be 30°, 32°, 32.5°, 33.3°, 34°, 36°, 40°, 42.7°, 43°, 45°. Of course, the angle α1 and the angle α2 are not limited to the specific values ​​listed above, and can be set according to actual use requirements, which will not be described in detail here.

[0076] Specifically, the beam angle can be 10°, 10.4°, 11°, 12.5°, 13°, 13.6°, 13.9°, 14°, 14.7°, 15°. Of course, the beam angle is not limited to the specific values ​​listed above, and it can be set according to actual use requirements, which will not be described in detail here.

[0077] In an optional embodiment, if Figure 6 , the RFID reader also includes a connecting rod 6;

[0078] The antenna 1 is fixedly connected to one end of the connecting rod 6;

[0079] The other end of the connecting rod 6 is semi-movably connected to the mainframe 3, so that when the connecting rod 6 is rotated, the pointed protrusion 4 can point to different directions.

[0080] In the embodiment of the present application, the other end of the connecting rod 6 is semi-movably connected to the host 3 to realize the steering function of the connecting rod 6, so that the pointed protrusion 4 can point to different directions. Specifically, the connecting rod 6 can rotate left and right, and the rotation step is 90°. When the host 3 is placed horizontally with the screen facing upward, from the direction of the host 3 toward the antenna 1, the pointed protrusion points to the 3 o'clock direction as the initial direction, such as Figure 7 (a); At this time, rotate the connecting rod 90° to the right, and the pointed protrusion can point to the 6 o'clock direction. Figure 7 (b); Continue to rotate the connecting rod 90° to the right, and the pointed protrusion 4 can point to the 9 o'clock direction, such as Figure 7 (c); Continue to rotate the connecting rod 90° to the right, and the pointed protrusion 4 can point to the 12 o'clock direction, such as Figure 7 (d) Similarly, the left connecting rod 6 is similar and will not be described in detail here.

[0081] It is understandable that in the existing network, there are generally four types of positional relationships between the RFID tag and the ODF port. The RFID tag is usually located directly above or below the ODF port, such as Figure 8 (a)- Figure 8 (b); In some cases, the RFID tag may also be located on the left or right side of the ODF port, such as Fig. 9 (a)- Fig. 9 (b) The steering function of the connecting rod 6 enables the antenna 1 to conveniently photograph the corresponding ODF port when it is close to the RFID tag in any case. Figure 8 (a) Figure 8 (b) Fig. 9 (a) and Fig. 9 The serial numbers 1-12 in (b) are the serial numbers of the ODF ports.

[0084] The storage module 34 is used to store information;

[0085] The display module 35 includes at least one display screen, which can display at least one of the following information: the port image being photographed, the battery level, the success / failure of the wireless communication connection, the success / failure of the RFID tag reading, etc. Optionally, the display module includes a touch screen, and some or all of the functions of the key module 33 can be implemented through the touch function of the touch screen, which is not limited in the embodiment of the present application.

[0086] Optionally, the display module includes a touch display screen, and part or all of the functions of the above-mentioned button module can be realized by the touch function of the touch display screen, which is not limited in the embodiment of the present application.

[0087] The LED module 36 includes at least one of a status display LED 361, an illumination LED 362, a button LED (not shown in the figure), and an orientation LED (not shown in the figure) on the antenna 1, and turns the relevant LED on / off according to the instruction sent by the main control module 32. The status display LED 361 is used to reflect the working status of the RFID reader, the illumination LED 362 is used to provide illumination, the button LED is used to reflect the status of the function button, and the orientation LED is used to display the direction or orientation of the antenna 1.

[0088] The voice module 37 is usually a buzzer, which plays the role of voice prompt. For example, different voice prompts are used when the wireless communication connection succeeds / failures and the RFID tag reading succeeds / failures.

[0089] The communication module 38 connects the main control module 32 and the terminal / cloud, and mainly transmits the data acquired / processed by the main control module 32 to the terminal / cloud via wireless communication methods such as Bluetooth, WIFI, 4G, and 5G.

[0090] In combination with the key module 33, the one-to-one identification and one-to-many identification methods of the RFID reader are specifically as follows:

[0091] One-to-one identification: short press the side button 336, then the light source module 5 on the antenna 1 lights up, and the display screen displays the port image captured by the camera module in real time; at this time, place the antenna 1 close to the RFID tag, rotate the connecting rod 6 or the RFID reader to align the optical axis direction of the camera module with the port to be photographed; press the side button 336 again, the light source module 5 on the antenna 1 goes out, and the RFID reader reads the identification information of the RFID tag and photographs the port.

[0092] One-to-many identification: First, bring the antenna 1 close to the RFID tag and press the RFID key 335 to read the identification information of the RFID tag. When it is necessary to collect the nth (e.g., 8th) port information identified by the RFID tag, first press the TID key 333 to call out the identification information of the nearest RFID tag, then aim the camera module of the RFID reader at the 8th port and press the side key 336 to shoot.
