[0002] Currently, due to the passive nature of optical distribution networks, the effective management of dumb resources such as optical fibers, splitters, and ports on optical distribution networks has always been a challenge in the field of ODN (Optical Distribution Network) resource management.
[0003] In related technologies, one management method is to install RFID (Radio Frequency Identification) tags on optical fiber cables and ODN equipment to uniquely identify the optical fiber cables and equipment point information. RFID reading and writing terminals can read and write the information content of passive electronic tags once or in batches to realize the binding of optical cables and equipment points.
[0004] However, this method can only identify fiber optic cables connected to the device, not the ports where the fiber optic cables are connected.
[0005] Therefore, it is necessary to design a new method and system for pairing ports of wiring devices to overcome the above problems. Summary of the Invention

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0022] In optical distribution networks, the current main management method is still the hierarchical management of paper labels. This method cannot realize the complete topology of the ODN and the distribution statistics of fiber core resources. Furthermore, the management of paper labels is generally maintained manually, and the label information cannot be strongly bound to the backend data, which easily leads to discrepancies between the records and the actual situation.
[0023] In recent years, to address the shortcomings of existing paper-based, passive resource management, several intelligent management technologies for ODNs have been proposed. One approach involves deploying miniaturized RFID (Radio Frequency Identification) tags at each port and jumper of the ODN facility. Each port and jumper is then individually bound and entered using a handheld data acquisition terminal. While this method digitizes passive nodes, the overall resource management efficiency remains low. Another approach involves deploying RFID tags near the connector of each optical cable and collecting tags in batches using a handheld terminal. However, this only establishes an association between the device and the optical cable, and cannot determine the port where the optical cable is located.
[0024] This application provides a method and system for pairing ports of a wiring device, which can solve the technical problem in related technologies that cannot identify ports connected to optical cables.
[0025] See Figure 1 As shown in the figure, this application embodiment provides a method for pairing ports of a wiring device, which may include: S100: Read device tag 110 and cable electronic tag 210.
[0026] S200: Obtain the correspondence between the device model and device port number and the characteristics of the tag's reflected signal based on device tag 110.
[0027] S300: Based on the tag reflection signal characteristics of the cable electronic tag 210 and the correspondence between the device port number and the tag reflection signal characteristics, pair the cable electronic tag 210 with the wiring device port; wherein, different ports of the wiring device 100 are provided with metal pieces 120 with different characteristics, and the metal pieces 120 are used to change the tag reflection signal characteristics.
[0028] See Figure 2 As shown, device tag 110 is located on wiring device 100 to identify the object information of wiring device 100. In this embodiment, wiring device 100 is an ODN device. Cable electronic tag 210 is located on the plug of cable 200 or on cable 200 near the plug to uniquely identify cable 200 and plug information. Each cable 200 is equipped with cable electronic tag 210. Cable electronic tag 210 and device tag 110 are passive electronic tags. Device tag 110 can also be a barcode to uniquely identify device information. Wiring device 100 has multiple ports. Metal piece 120 can be provided on each port, or metal piece 120 can be not provided on one port. The characteristics of metal piece 120 are different on different ports. Metal piece 120 identifies device ports. Different characteristics of metal piece 120 are installed on wiring device 100 or on ports near cable electronic tag 210. At most one port can be without metal piece 120. Preferably, the cable electronic tag 210 can be an electronic tag with an indicator light, which can locate the cable 200 to be operated by turning on the light.
[0029] This embodiment sets metal pieces 120 with different characteristics at different ports of the wiring device 100. The disturbance effect of metal on the electromagnetic field causes changes in the characteristics of the tag reflection signal. Metal pieces 120 with different characteristics or different positions relative to the cable electronic tag 210 can obtain different tag reflection signal characteristics. By the difference in tag reflection signal characteristics, the connection status of the cable 200 and the corresponding port can be determined, which solves the technical problem in related technologies that the port of optical cable connection cannot be accurately identified.
[0030] In the above embodiment, the cable electronic tag 210 is an RFID (Radio Frequency Identification) tag. The RFID reader / writer terminal 300 can read the device tag 110 and the cable electronic tag 210 in batches, and perform the steps S200 and S300 described above, pairing and binding the cable electronic tag 210 with the wiring device port. By analyzing the characteristics of the tag's reflected signal, the cable 200 is accurately associated with the port, and the occupancy status of each port of the device is obtained.
[0031] Furthermore, in one embodiment, the differences in features include, but are not limited to, differences in the structure, shape, or size of the metal sheet 120, or differences in the relative positions of the metal sheet 120 at each port of the wiring device 100. In this embodiment, the structure, shape, or size of the metal sheet 120 in each port can be designed differently, and the metal sheets 120 in different ports can be placed in different positions. For example, along the insertion direction of the cable 200, the distance between the metal sheet 120 and the cable electronic tag 210 can be different, or the position of the metal sheet 120 relative to the cable electronic tag 210 can be different in various directions, all of which can achieve different tag reflection signal characteristics at different ports.
[0032] In this embodiment, the shapes of the metal pieces 120 in different ports can be designed differently, or they can be designed with the same shape but different sizes, or they can have different shapes and different sizes. See also Figure 3 As shown, four ports are displayed, labeled with square, circle, triangle, and L-shape respectively, representing ports 101 to 104.
[0033] Furthermore, in one embodiment, the relative position includes, but is not limited to, the horizontal and vertical distance and angle between the cable electronic tag 210 and the port. The horizontal distance is the distance along the length or width of the cable electronic tag 210, and the vertical distance is the distance along the vertical direction of the cable electronic tag 210.
[0034] Furthermore, in one embodiment, the characteristics of the tag's reflected signal include, but are not limited to, resonant frequency, radio frequency signal strength, or phase. Specifically, only the resonant frequency may be collected, and the port to be assigned is determined based on a comparison of the resonant frequency; or only the radio frequency signal strength or phase may be collected; alternatively, both the resonant frequency and radio frequency signal strength may be collected, and the port to be assigned is determined based on a comparison of these two; or the resonant frequency, radio frequency signal strength, and phase may be collected, and the port to be assigned is determined based on a comparison of all three. In other embodiments, in addition to the resonant frequency, radio frequency signal strength, and phase, other characteristics may be collected for comparison and determination.
[0035] Furthermore, in some embodiments, before obtaining the correspondence between the device model and device port number and the tag reflection signal characteristics based on the device tag 110, it may also include: collecting the tag reflection signal characteristics of the cable electronic tags 210 under all ports of the device, and establishing the correspondence between the device port number and the tag reflection signal characteristics.
[0036] In this embodiment, the wiring device 100 has multiple ports, and the overlapping metal plates 120 interact with each other. The characteristics of the metal plates 120 with significantly different tag reflection signal features are selected; the characteristics of the metal plates 120 differ at different ports of the wiring device. For example... Figure 3 The example wiring device 100 has four ports, labeled with square, round, triangular, and L-shaped markings respectively for ports 101 to 104. Metal plates 120 can be permanently fixed relative to each port using processes such as one-piece injection molding, ensuring consistency of the metal plates 120 across all ports of the wiring device 100. A cable 200 with an electronic cable tag 210 is inserted into each port for testing. The electronic cable tag 210 for port 101 is 202-1, for port 102 it is 202-2, for port 103 it is 202-3, and for port 104 it is 202-4. The RFID reader / writer 300 reads all cable electronic tags 210. The initial resonant frequency of the cable electronic tags 210 is f0. The resonant frequencies f1, f2, f3, and f4 of tags 202-1, 202-2, 202-3, and 202-4 are stored, corresponding to the first port 101, the second port 102, the third port 103, and the fourth port 104, respectively. A correspondence is established between the port numbers of the wiring device 100 and the resonant frequencies of the cable electronic tags 210, as shown in Table 1. This established correspondence can be stored in a database.
[0037] Table 1. Correspondence between device port number and tag reflected signal characteristics
[0038] Furthermore, in one embodiment, pairing the cable electronic tag 210 with the wiring device port based on the tag reflection signal characteristics of the cable electronic tag 210 and the correspondence between the device port number and the tag reflection signal characteristics includes: if the difference between the tag reflection signal characteristics of one of the cable electronic tags 210 and the tag reflection signal characteristics corresponding to one of the wiring device ports is less than a set deviation, then pairing the cable electronic tag 210 with the wiring device port.
[0039] In this embodiment, metal pieces 120 of different shapes and sizes are embedded in the field device ports. By analyzing the characteristics of the tag reflection signals received by the RF reader / writer 300, the port to which the cable electronic tag 210 belongs is determined. See example. Figure 4As shown, the first port 101, second port 102, third port 103, and fourth port 104 of the wiring device 100 are each embedded with metal pieces 120 of different characteristics, and cable electronic tags 210 are installed on the plugs of the cable 200. The radio frequency reader / writer 300 collects the device tag 110. The three cable electronic tags 210 are 210-1, 210-2, and 210-3, respectively. Based on the device tag 110, the device model and the correspondence between the device port and tag features stored in the database are obtained. The reflected signal features of the cable 200 tag are extracted and compared with the tag reflected signal features in the correspondence table of device port number and tag reflected signal features in the database. If the resonant frequency f210-1 of the reflected signal of tag 210-1 is close to the resonant frequency f1 of the tag corresponding to the first port 101 in the correspondence table, and the frequency difference between f210-1 and f1 is less than the set deviation Δf, then tag 210-1 is paired with the first port 101. The same method is used to pair tag 210-2 with the second port 102 and tag 210-3 with the fourth port 104, achieving precise correspondence between the plug and port of cable 200. If the frequency of the cable electronic tag 210 is f0, it indicates that cable 200 is not inserted into the device port. The frequency deviation Δf is set to be less than half the difference between any two resonant frequencies in the correspondence table f1, f2, f3, f4.
[0040] Furthermore, in some optional embodiments, the reading of the device tag 110 and cable electronic tag 210 may include: using a drone equipped with an RFID reader / writer 300 to read the device tag 110 and cable electronic tag 210 from multiple angles on the wiring device 100. Wiring devices 100 are mostly pole-mounted, making manual data collection time-consuming and labor-intensive, and it is difficult to fix the relative position of the reader / writer and the device. This embodiment uses a drone equipped with an RFID reader / writer 300 to perform 360-degree data collection from a set distance on the wiring device 100, allowing for multi-dimensional comparison of tag reflection signal characteristics, resulting in more accurate plug-to-port pairing.
[0041] In this embodiment, see Figure 3 As shown, metal pieces 120 are added to the ports of the wiring device 100, and the characteristics of the metal pieces 120 are different for different ports of the wiring device. A test cable electronic tag 210 is added to the plug of the cable 200 at each port. For example, the plug tag (i.e., cable electronic tag 210) of the first port 101 is 202-1, the plug tag of the second port 102 is 202-2, the plug tag of the third port 103 is 202-3, and the plug tag of the fourth port 104 is 202-4. The RF reading and writing terminal 300 reads all plug tags of the wiring device 100 at a set distance in a 360° range, extracting the resonant frequency offset, RSSI (radio frequency signal strength) fluctuation, and phase change value of the tags. A correspondence between the port number of each type of wiring device 100 and the tag reflection signal characteristics is established, as shown in Table 2.
[0042] Table 2. Correspondence between device port number and tag reflected signal characteristics
[0043] For example, see Figure 5 As shown, the on-site RFID reader / writer 300 performs 360° tag acquisition at a set distance from the wiring device 100. By comparing and analyzing the characteristics of the tag reflection signals received by the RFID reader / writer 300, the port to which the cable electronic tag 210 belongs is determined. The RFID reader / writer 300 acquires plug tags 210-1, 210-2, and 210-3, extracts features such as tag resonant frequency, phase difference, and RSSI fluctuation, and compares them with data in the database (i.e., the correspondence between device port number and tag reflection signal characteristics). The three features are combined to determine the port to which the cable electronic tag 210 belongs.
[0044] In one embodiment, the tag reflection signal characteristics include resonant frequency, phase, and radio frequency signal strength. The step of pairing the cable electronic tag 210 with the wiring device port based on the tag reflection signal characteristics of the cable electronic tag 210 and the correspondence between the device port number and the tag reflection signal characteristics includes: S301: Compare the resonant frequency of the cable electronic tag 210 with the resonant frequency corresponding to each wiring device port, compare the phase of the cable electronic tag 210 with the phase corresponding to each wiring device port, and compare the radio frequency signal strength of the cable electronic tag 210 with the radio frequency signal strength corresponding to each wiring device port.
[0045] S302: Based on the comparison results of the resonant frequency, phase, and radio frequency signal strength of the cable electronic tag 210, determine the port to which the cable electronic tag 210 belongs.
[0046] In this embodiment, when jointly judging the three features, one approach is to assign different weights to the resonant frequency shift, phase difference, and RSSI fluctuation, and then make a comprehensive comparison. Another approach is to judge them sequentially; for example, if the resonant frequency shift cannot determine the result, then the phase is compared, and finally the RSSI is compared.
[0047] See Figure 2As shown in the figure, this application embodiment also provides a wiring device port pairing system, which includes: a passive electronic tag, including a cable electronic tag 210 and a device tag 110; a plurality of metal pieces 120, the plurality of metal pieces 120 having different characteristics, and the metal pieces 120 with different characteristics being used to be disposed on different ports of the wiring device 100 to change the tag reflection signal characteristics; and an RF read / write terminal 300, which is used to read the device tag 110 and the cable electronic tag 210, obtain the correspondence between the device model and the device port number and the tag reflection signal characteristics according to the device tag 110, and pair the cable electronic tag 210 with the wiring device port according to the tag reflection signal characteristics of the cable electronic tag 210 and the correspondence between the device port number and the tag reflection signal characteristics.
[0048] In this embodiment, the device tag 110 is located on the wiring device 100 to identify the object information of the wiring device 100. In this embodiment, the wiring device 100 is an ODN device. The cable electronic tag 210 is located on the plug of the cable 200 or on the cable 200 near the plug to uniquely identify the cable 200 and plug information. Each cable 200 is equipped with a cable electronic tag 210. The cable electronic tag 210 and the device tag 110 are passive electronic tags. The device tag 110 can also be a barcode to uniquely identify device information. The wiring device 100 has multiple ports. A metal piece 120 can be provided on each port, or a metal piece 120 can be not provided on one of the ports. The characteristics of the metal pieces 120 on different ports are different. The metal piece 120 identifies the device port. Different metal pieces 120 with different characteristics are installed on the wiring device 100 or on the port near the cable electronic tag 210. At most one port can be without a metal piece 120. Preferably, the cable electronic tag 210 can be an electronic tag with an indicator light, which can locate the cable 200 to be operated by turning on the light.
[0049] In this embodiment, a cable 200 with a cable electronic tag 210 is inserted into a port of the wiring device 100. The RF reader / writer terminal 300 operates, and the tag reflection signal characteristics of the cable 200 change due to the influence of the metal piece 120. Based on the analysis of the read tag reflection signal characteristics, the port to which the cable 200 plug belongs is determined. The RF reader / writer terminal 300 can batch collect cable electronic tags 210 inserted into each port, analyze the tag reflection signal characteristics, and establish a correlation between the tag reflection signal characteristics and the characteristics of the metal piece 120, i.e., the correlation between the tag reflection signal characteristics and the port. The RF reader / writer terminal 300 can also batch collect device tags 110 and cable electronic tags 210, and based on the correlation between the tag reflection signal characteristics and the port, pair and bind the cable electronic tags 210 with the device ports by analyzing the tag reflection signal characteristics.
[0050] In this embodiment, metal sheets 120 of different sizes and shapes are added around the cable electronic tag 210. The disturbance effect of the metal on the electromagnetic field causes changes in the signal characteristics of the cable electronic tag 210. The RF reader / writer terminal 300 reads the signal of the cable electronic tag 210 and analyzes its signal characteristics. The characteristics of the metal sheet 120 include, but are not limited to: shape, size, position, and distance from the cable electronic tag 210. The tag's reflected signal characteristics include, but are not limited to: resonant frequency, RSSI (radio frequency signal strength), and phase.
[0051] This application embodiment also provides another wiring device port pairing system, which includes: a wiring device 100, the wiring device 100 having multiple ports, different ports having metal pieces 120 with different characteristics, and the wiring device 100 having a device tag 110; multiple cables 200, each cable 200 having a cable electronic tag 210; and an RF reader / writer terminal 300, which is used to read the device tag 110 and the cable electronic tag 210, obtain the correspondence between the device model and device port number and the tag reflection signal characteristics based on the device tag 110, and pair the cable electronic tag 210 with the wiring device port based on the tag reflection signal characteristics of the cable electronic tag 210 and the correspondence between the device port number and the tag reflection signal characteristics.
[0052] In this embodiment, the characteristics of the metal sheet 120 include, but are not limited to: shape, size, position and distance from the cable electronic tag 210. The characteristics of the tag's reflected signal include, but are not limited to: resonant frequency, RSSI (radio frequency signal strength), phase, etc.
[0053] In this embodiment, the ports of the wiring device 100 are embedded with metal pieces 120 of different characteristics. The metal pieces 120 can be pre-installed in the ports, such as by injection molding the metal piece 120 integrally with the port; or they can be installed later. Each port is plugged with a cable electronic tag 210. The RF reader / writer terminal 300 collects the signal characteristics of the cable electronic tag 210 and establishes a correspondence between the signal characteristics of the cable electronic tag 210 for that model of device and the port number. The wiring device 100 carries a device tag 110 (electronic tag), whose ID contains the device model information; the cable 200 plug carries a cable electronic tag 210, which has a unique ID number. The device tag 110 and cable electronic tag 210 can be pre-installed at the factory or installed on-site. The RF reader / writer terminal 300 activates group reading mode to read all electronic tags installed on the device and cable 200 in batches. Based on the device model obtained from the device tag 110, it obtains the correspondence between the port number of that model of device and the tag's reflected signal characteristics. Based on the tag's reflected signal characteristics, the read cable electronic tag 210 is matched with the port.
