[0044] 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.

[0045] It is worth noting that, in the prior art, it is necessary to install an RFID tag at each ODF port, such as Figure 1 In a 12-core ODF device, 12 ODF ports 7 need to be installed with 12 RFID tags 8, which has the following problems:

[0046] (1) Excessive use of RFID tags results in waste of resources:

[0047] (2) RFID tags are spaced very close together, making installation difficult;

[0048] (3) The RFID tags are closely spaced, making it difficult for the RFID reader to collect data. When an RFID tag is read, adjacent RFID tags emit signals in response, interfering with each other.

[0049] (4) It is not convenient to install RFID tags on very small optical fiber devices, such as optical fibers in optical cables, which results in the ODF port being unable to use the identification information of the RFID tag for identification.

[0050] In view of this, the present application provides an RFID reader, which has a built-in gyroscope in the RFID reader so that the gyroscope measures the current rotation angle of the RFID reader, and determines the identification information of the port to be identified by the RFID tag according to the current rotation angle and the identification information of the RFID tag. Under the premise of ensuring that each ODF port can be identified, there is no need to install an RFID tag for each ODF port, thereby reducing the use of RFID tags, avoiding waste of resources, and reducing costs. When one RFID tag is used to identify four ODF ports, the RFID tag and installation cost is only about 25% of the original solution.

[0051] In addition, the gap between RFID tags can be increased, thereby reducing the difficulty of installation, reducing signal interference between adjacent RFID tags, and improving the accuracy of RFID tag identification information collection, which is suitable for various types of equipment with ports / components with identification, especially small-volume optical fiber equipment. The embodiment of the present application simplifies the installation process of RFID tags, reduces the difficulty of installation and the complexity of operation, so that when carrying out large-scale digital transformation, the deployment of RFID tags for various types of equipment can be completed more quickly, shortening the project cycle and improving the overall construction efficiency.

[0052] See also Figure 2 , Figure 2 : is a structural block diagram of an RFID reader provided in an embodiment of the present application, wherein the RFID reader comprises:

[0053] Antenna 1, used to receive the radio frequency signal sent by the RFID tag;

[0054] A radio frequency module 21, used for transmitting the radio frequency signal;

[0055] A gyroscope 22, used to measure the current rotation angle of the RFID reader; the current rotation angle is used to indicate the port to be identified by the RFID tag;

[0056] The control module 23 is used for:

[0057] Receive and analyze the radio frequency signal transmitted by the radio frequency module 21 to obtain the identification information of the RFID tag;

[0058] Acquire the current rotation angle measured by the gyroscope 22 to determine the identification information of the port based on the current rotation angle and the identification information of the RFID tag; or acquire and send the current rotation angle measured by the gyroscope 22 to the resource management system so that the resource management system determines the identification information of the port based on the current rotation angle and the identification information of the RFID tag.

[0059] In the embodiment of the present application, the identification information of the RFID tag is read by the RFID reader; 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 control module 23 through the radio frequency module 21. The control module 23 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.

[0060] The RFID reader is also provided with a gyroscope 22 for measuring the current rotation angle of the RFID reader; the gyroscope 22 can measure the current rotation angle of the RFID reader around any axis, which is not specifically limited in the embodiment of the present application. In addition, in addition to feeding back the rotation angle of the RFID reader around any axis to the control module 23, the gyroscope 22 can also feed back the acceleration of the RFID reader around any axis.

[0061] For example, Figure 3 The RFID reader includes an RFID reader body 2 (including a radio frequency module 21, a control module 23 and a gyroscope 22), an antenna connecting rod 3 and an antenna 1. The RFID reader body 2 is connected to the antenna 1 through the antenna connecting rod 3. The gyroscope 22 is used to measure the current rotation angle of the RFID reader around the y-axis. The y-axis is the direction in which the RFID reader body 2 points to the antenna 1, and is also the direction in which the antenna connecting rod 3 points to the antenna 1. When the RFID reader rotates left and right around the y-axis, the gyroscope 22 feeds back the current rotation angle α of the RFID reader around the y-axis, which ranges from -90° to 90°. α of 0° indicates that the RFID reader is in a horizontal position (the left and right sides of the RFID reader are at the same height from the ground). When the RFID reader rotates to the right, α can increase to 90°, and when it rotates to the left, α can decrease to -90°.

[0062] The working principle of the RFID reader provided in the embodiment of the present application is to place the RFID reader antenna 1 close to the RFID tag, read the identification information of the RFID tag, and then change the current rotation angle of the RFID reader by rotating the RFID reader to determine the port to be identified by the RFID tag, so that the RFID reader or resource management system determines the identification information of the port based on the current rotation angle and the identification information of the RFID tag.

[0063] After obtaining the current rotation angle and the identification information of the RFID tag, the control module 23 can determine the identification information of the port based on the current rotation angle and the identification information of the RFID tag, and then transmit the identification information of the port to the resource management system so that the resource management system obtains the identification information of the port.

[0064] After obtaining the current rotation angle and the identification information of the RFID tag, the control module 23 may also directly send the current rotation angle and the identification information of the RFID tag to the resource management system, so that the resource management system receives the current rotation angle and the identification information of the RFID tag to determine the identification information of the port;

[0065] After obtaining the identification information of the port, the resource management system associates the port with the identification information of the port to identify the port, and then manages the occupancy, connection relationship and other information of the port according to the identification information of the port.

[0066] 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.

[0067] In an optional embodiment, determining the identification information of the port according to the current rotation angle and the identification information of the RFID tag includes:

[0068] According to the mapping relationship between the preset rotation angle and the port initial identification information, the current port initial identification information corresponding to the current rotation angle is obtained;

[0069] The identification information of the port is determined according to the initial identification information of the current port and the identification information of the RFID tag.

[0070] In an optional embodiment, the determining the identification information of the port according to the current rotation angle and the identification information of the RFID tag further includes:

[0071] Obtaining the current port initial identification information corresponding to the current rotation angle through the mapping relationship between the preset rotation angle and the port initial identification information;

[0072] The identification information of the RFID tag and the initial identification information of the current port are concatenated to obtain the identification information of the port.

[0073] In the above embodiment, the mapping relationship between the rotation angle and the initial identification information of the port can be preset by the manufacturer during manufacturing, such as embedded software burning, or preset during product debugging, or the user can personalize it according to the number and angle range of the ports, which is not specifically limited here. In addition, since the sizes of ports of different manufacturers may be different to a certain extent, the mapping relationship can be set according to actual needs, which is not specifically limited here.

[0074] The mapping relationship can be used to obtain the current port initial identification information corresponding to the current rotation angle; and then the identification information of the port is determined according to the current port initial identification information and the identification information of the RFID tag, specifically: the identification information of the RFID tag and the current port initial identification information are spliced ​​to obtain the identification information of the port. Specifically, the current port initial identification information can be spliced ​​at any position of the identification information of the RFID tag, which is not specifically limited here.

[0075] Optionally, the initial port identification information is a port number, which can be a hexadecimal character. For example, the port number of the port to be identified is obtained according to the current rotation angle, and the identification information of the RFID tag is read at the same time, and the port number is spliced ​​at the end of the identification information of the RFID tag to obtain the identification information of the port. Such an RFID tag can form identification information of up to 16 ports, that is, up to 16 ports can be identified.

[0076] For example, the TID of a certain RFID tag is E20034120614141100734886 (24-bit hexadecimal). By rotating the RFID reader so that its current rotation angle points to the second port to be identified by the RFID tag, the current port initial identification information of the port is obtained as 2. Then, by splicing at the end of the TID, the identification information of the port is obtained as: E200341206141411007348862. Since the TID of each RFID tag is unique, the identification information of the port formed by splicing a different hexadecimal character at the end of the TID is still unique. In this way, each port can have a unique identification information.

[0077] In order to reduce the misjudgment of the RFID reader, in the mapping relationship, each rotation angle (-90° to 90°) is not provided with corresponding port initial identification information, but a gap angle is left between adjacent ports, and when the rotation angle is at the gap angle, it does not point to any port. Optionally, the size of the gap angle is 5° to 10°.

[0078] For example, 40°≤α≤85° corresponds to the first port, then when 40°≤α≤85°, it indicates that it points to the first port; the clearance angle between the first port and the second port is 30°~40°, then when 30°<α<40°, it indicates that it does not point to any port; 30°≤α≤-30° corresponds to the second port, then when 30°≤α≤-30°, it indicates that it points to the second port; the clearance angle between the second port and the third port is -30°~-40°, then when -40°<α<-30°, it indicates that it does not point to any port, and -85°≤α≤-40° corresponds to the third port, then when -85°≤α≤-40°, it indicates that it points to the third port.

[0079] Specifically, the size of the clearance angle can be 5°, 5.5°, 6°, 6.8°, 6.9°, 7°, 8°, 9.1°, 9.5°, 10°. Of course, the size of the clearance angle is not limited to the specific values ​​listed above, and it can be set according to actual use requirements, and no further details are given here.

[0080] In an optional embodiment, the antenna 1 is further provided with a pointed protrusion 4, and the pointed protrusion 4 is used to point to the port to be identified.

[0081] In an embodiment of the present application, in order to allow the user to directly observe which port to be identified is indicated by the current rotation angle, a pointed protrusion 4 is further provided on the antenna 1, so that the pointed protrusion 4 points to the port to be identified, so that when the current rotation angle indicates which port to be identified, the pointed protrusion 4 points to the same port.

[0082] For example, every three ports form a group, and the ports in the same group are marked with the same RFID tag. The antenna of the RFID reader is provided with a pointed protrusion 4. When the RFID reader is placed horizontally (the left and right sides of the RFID reader are at the same height from the ground), the pointed protrusion 4 points vertically downward, and α=0. When marking a port, the antenna 1 of the RFID reader is brought close to the RFID tag, and the RFID reader is rotated so that the pointed protrusion 4 points to the port to be marked. Figure 4 In the scenario of identifying the ODF port, when the pointed protrusion 4 points to the first ODF port in a group, 40°≤α≤85°; when the pointed protrusion 4 points to the second ODF port in a group, 30°≤α≤-30°; when the pointed protrusion 4 points to the third ODF port in a group, -85°≤α≤-40°.

[0083] In an optional embodiment, a first light source module 5 is further provided on the pointed protrusion 4 , and the first light source module 5 is used to provide a light spot pointing to the port to be marked, and the direction of the light spot is consistent with the direction of the pointed protrusion 4 .

[0084] In the embodiment of the present application, in order to more clearly observe which port to be identified is indicated by the current rotation angle, a first light source module 5 is also provided on the pointed protrusion 4, so that the light spot provided by the first light source module 5 points to the port to be identified, and the light spot is consistent with the direction of the pointed protrusion 4, so that when the current rotation angle indicates which port to be identified, the pointed protrusion 4 points to the same port, and the light spot of the first light source module 5 also points to the same ODF port. By observing which port is illuminated by at least a part of the light spot of the first light source module 5, the port to be identified can be known. In some cases, such as when the light spot of the first light source module 5 is relatively concentrated, or the area of ​​a port is relatively large, the light spot can illuminate all or most of a port to be identified.

[0085] In an optional embodiment, the control module 23 is further used for:

[0086] In response to the current rotation angle being in accordance with the rotation angle range within the mapping relationship, the first light source module 5 is controlled to emit the light spot; the mapping relationship is a mapping relationship between the rotation angle and the initial identification information of the port.

[0087] In an embodiment of the present application, in order to reduce the misjudgment of the RFID reader, the control module 23 stores a mapping relationship between a preset rotation angle and the initial identification information of the port, or the control module 23 obtains a mapping relationship between a preset rotation angle and the initial identification information of the port, so that when the current rotation angle is consistent with the rotation angle range within the mapping relationship, the first light source module 5 is controlled to emit the light spot, which points to the port to be identified.

[0088] In addition, the antenna 1 may also be provided with a second light source module 6, which is arranged on the same surface of the pointed protrusion as the first light source module 5 and is close to the first light source module 5. The light source color of the first light source module 5 is different from the light source color of the second light source module 6, so that when the current rotation angle does not conform to the rotation angle range within the mapping relationship, the second light source module 6 is controlled to emit a light spot, and by observing the color of the light spot at this time, it can be known which port the current rotation angle indicates. For example, the light source color of the first light source module 5 is green, and the light source color of the second light source module 6 is red. When the green light is on, it indicates that the pointed protrusion 4 is pointing to the port to be identified, and when the red light is on, it indicates that the pointed protrusion 4 is not pointing to the port to be identified.

[0089] In an optional embodiment, if Figure 5-Figure 8 When the RFID reader is placed horizontally, the pointed protrusion 4 points vertically downward, the angle β between the installation direction of the first light source module 5 and the horizontal plane is 30° to 45°, and the beam angle of the first light source module 5 is 10° to 15°. Figure 5-Figure 8Schematic diagram of the structure formed by the antenna connecting rod 3, the antenna 1, the first light source module 5 and the second light source module 6 at various viewing angles. The first light source module 5 is arranged on the side of the pointed protrusion 4 away from the RFID reader body, and the surface is inclined so that the angle β between the installation direction of the first light source module 5 and the horizontal plane is 30° to 45°; the vertical direction of the surface is the installation direction of the first light source module 5, that is, the angle between the surface and the installation direction of the first light source module 5 is 90°; and the size of the angle β is the same as the size of the angle β' between the installation direction of the first light source module 5 and the side where the pointed protrusion 4 of the antenna 1 is located, then the first light source module 5 is arranged on the side of the pointed protrusion 4 away from the RFID reader body, and the angle between the surface and the side where the pointed protrusion 4 of the antenna 1 is located is (90°+30°) to (90°+45°).

[0090] Specifically, the angle β can be 30°, 31.1°, 32°, 33°, 34.5°, 35°, 42°, 43.7°, 44°, 45°. Of course, the angle β is 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.

[0091] Specifically, the beam angle can be 10°, 11°, 12.6°, 12.9°, 13°, 13.2°, 13.3°, 14°, 14.4°, 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.

[0092] If the angle β and the beam angle are too large or too small, it will affect the position of the light spot emitted by the first light source module 5. In the embodiment of the present application, the angle β is preferably 30° to 45° and the beam angle is 10° to 15°, so that most of the light spot emitted by the first light source module 5 is irradiated onto the port, further ensuring that the direction of the light spot is consistent with the direction of the pointed protrusion. Similarly, the angle between the installation direction of the second light source module 6 and the horizontal plane is preferably 30° to 45°, and the beam angle of the second light source module 6 is preferably 10° to 15°, which will not be further elaborated here.

[0093] For example, Figure 9-10 The RFID reader provided in the embodiment of the present application may also include: a button module 24, a storage module 25, a display module 26, an LED module 27, a voice module 28, a communication module 29, a lithium battery and a corresponding charging module (not shown in the figure), etc., wherein the button module 24, the storage module 25, the display module 26, the LED module 27, the voice module 28, and the communication module 29 can be arranged in the RFID reader body.

[0098] The LED module 27 includes at least one of a status display LED 271, an illumination LED 272, a key 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 control module 23. The status display LED 271 is used to reflect the working status of the RFID reader, the illumination LED 272 is used to provide illumination, the key LED is used to reflect the status of the function key, and the orientation LED is used to display the direction or orientation of the antenna 1.

[0099] The voice module 28 is usually a buzzer, which plays the role of a voice prompt. For example, different voice prompts are used when the wireless communication connection succeeds / failed, and when the RFID tag is read successfully / failed.

[0100] The communication module 29 connects the control module 23 and the terminal / cloud, and mainly transmits the data acquired / processed by the control module 23 to the terminal / cloud via wireless communication methods such as Bluetooth, WIFI, 4G, and 5G.

[0101] The port identification method of the RFID reader provided in the embodiment of the present application has one or more modes:

[0102] One-to-one method: bring the antenna 1 of the RFID reader close to the RFID tag and press the "RFID" key to complete the identification. Specifically, when the RFID reader identifies in a one-to-one manner, according to the guidance of the terminal APP or the RFID reader's own APP, bring the antenna 1 of the RFID reader close to the RFID tag and press the "RFID" key to complete the identification of a certain port.

[0103] One-to-many mode: by rotating the RFID reader so that the pointed protrusion 4 of the antenna 1 points to the ODF port to be identified, the identification is completed using the first light source module 5 and the side button. Specifically, when the RFID reader is identified in a one-to-many mode, according to the guidance of the terminal APP or the RFID reader's own APP, after selecting a specific one-to-many mode (for example: one-to-two, one-to-three, one-to-four, one-to-five, one-to-six, etc.), the antenna 1 of the RFID reader is brought close to the RFID tag, and the RFID reader is rotated so that the pointed protrusion 4 of the antenna 1 points to the ODF port to be identified. If the first light source module 5 emits a light spot at this time, press the side button 246 to complete the identification of a certain ODF port.

[0104] One-to-many quick reading mode: The RFID reader will automatically store the identification information of the RFID tag collected the most recently. In quick reading mode, rotate the RFID reader, and the RFID reader will prompt 1, 2, 3...N (N is based on the one-to-many mode set, the maximum is 16) in turn according to the current rotation angle and display them on the screen. When a certain number appears, press the side button 246, and the RFID reader will add a hexadecimal number corresponding to the number displayed on the screen after the stored TID code to form a new ID.

[0105] Specifically, the quick reading mode can be entered by pressing the TID key 243 or by shaking the RFID reader after pressing and holding the side button 246 (or detecting that the acceleration of the x, y or z axis of the gyroscope 22 exceeds a preset value). In the quick reading mode, rotate the RFID reader, and the RFID reader will prompt the numbers 1, 2, 3...N in turn according to the current rotation angle and display them on the screen. When a certain number (for example, "3") appears, press the side button 246, which is equivalent to bringing the antenna 1 of the RFID reader close to the RFID tag that collected information last time and rotating the RFID reader so that the pointed protrusion 4 of the antenna 1 points to the third ODF port and pressing the side button 246. In this way, when multiple ODF ports under the same RFID tag need to be collected at one time, there is no need to frequently bring the antenna 1 of the RFID reader close to the RFID tag, thereby improving the identification efficiency.

[0106] The quick reading mode can also be used to identify small fiber optic devices that are not easy to install labels (such as optical fibers in optical cables), or when the mapping relationship between the existing rotation angle and the initial identification information of the ODF port cannot be applied to the multiple ODF ports identified and the current rotation angle.
