[0046] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] FIG1 is a schematic diagram showing the structure of a cabinet cable management system provided in the prior art.

[0048] The cabinet cable management system includes network equipment, a monitoring host, a management unit, optical distribution frames, copper distribution frames, power supply equipment, supporting power supply cables, optical cables, copper cables, and user terminal equipment. The network equipment, monitoring host, management unit, optical distribution frames, and copper distribution frames are all connected to the power supply equipment via corresponding supporting power supply cables. Furthermore, the copper and optical distribution frames require special customization and contain a printed circuit board (PCB) that displays the access status of each optical or copper port. Optical and copper patch cables also require special customization and contain metal conductors that physically contact the PCB, enabling the PCB to operate through conduction or grounding. When an optical or copper cable is inserted into the corresponding port, an indicator light on the PCB board of the port with the optical or copper cable inserted illuminates, and the access status of that port is fed back to the management unit and monitoring host, thereby updating the network structure information.

[0049] The existing cabinet cable management system has the following shortcomings:

[0050] 1) Existing cabinet cable management systems require additional management units, power supplies or communication lines between the management units and the patch panel, and power supplies or communication lines between the management units and the monitoring host, increasing cabling costs and difficulty.

[0051] 2) It is necessary to power network equipment, monitoring hosts, management units, optical distribution frames, and copper distribution frames, thus increasing energy consumption;

[0052] 3) Each port requires a PCB board, which increases hardware costs.

[0053] It can be seen that the existing technology changes the layout structure of the traditional computer room by additionally configuring management units, monitoring hosts and PCB boards, resulting in problems such as high hardware costs, difficult wiring and increased energy consumption.

[0054] In order to solve the technical problems existing in the prior art, the embodiments of the present application provide a cabinet cable management method and system based on Radio Frequency Identification (RFID), in which RFID tags are respectively set on cables and ports, and a cable management database is established through user terminal devices based on the tag information of the RFID tags on the cables and ports, thereby realizing intelligent and convenient management of cables in a computer room or cabinet based on the cable management database, with low cost and low energy consumption.

[0055] Figure 2 shows a schematic diagram of the structure of an RFID-based cable management system provided in an embodiment of the present application. The RFID-based cable management system 1 may include: multiple traceable cables 4, a patch panel 3, an RFID reader / writer 2, a power supply, and user terminals. The patch panel 3, RFID reader / writer 2, and power supply may be integrated into a cabinet. The RFID reader / writer 2 may include an RFID tag reader / writer module and a communication module. The communication module of the RFID reader / writer 2 can implement both wired and wireless communication.

[0056] In one embodiment, the RFID-based cable management system 1 may further include a network device 5. The network device 5 may be a switch or router, etc., and is used to communicate with user terminal devices. Some computer rooms have good wireless signals, while others have poor wireless signals. Therefore, to adapt to the needs of different application environments, in computer rooms with poor wireless signals, a wired network device 5 may be used to transmit information. The wired network device 5 may be integrated into a cabinet, as shown in FIG3 , for ease of management. In computer rooms with good wireless signals, the RFID reader / writer 2 may use wireless network communication to transmit information with user terminal devices. That is, the RFID reader / writer 2 may directly send the read information to the user terminal device, or directly receive instructions sent by the user terminal device, as shown in FIG4 , for ease of operation. Except in computer rooms with poor wireless signals, the RFID reader / writer 2 needs to use wired communication to connect to the network device 5, sending the information it reads to the user terminal device through the network device 5, or receiving instructions sent by the user terminal device by receiving instructions from the network device 5.

[0057] The patch panel 3 is used to connect the multiple traceable cables 4, as shown in Figure 5. To meet the requirements for diverse signal transmission in a computer room or cabinet, the multiple traceable cables 4 may include, but are not limited to, multiple traceable optical cables and multiple traceable copper cables. Accordingly, the patch panel 3 may include, but is not limited to, an optical patch panel and a copper patch panel. The optical patch panel includes multiple optical ports, each of which is used to connect to the traceable optical cable. The copper patch panel includes multiple copper ports, each of which is used to connect to the traceable copper cable. The patch panel 3 facilitates centralized wiring by construction workers and facilitates the inspection and replacement of cables (optical and copper cables) after wiring.

[0058] In one embodiment, each of the traceable optical cables and each of the traceable copper cables is provided with a first RFID tag, which uniquely identifies the corresponding cable and enables tracking and locating the corresponding cable. Each optical port of the optical distribution frame and each copper port of the copper distribution frame is provided with a second RFID tag, which uniquely identifies the position of the corresponding port 31 and enables tracking and locating the corresponding port 31. The first RFID tag provided on the traceable cable 4 and the second RFID tag provided on the port 31 can both be passive RFID tags, which can be freed from the constraints of power supply equipment and reduce power consumption. The first RFID tag and the second RFID tag carry different tag information: the first RFID tag carries first tag information, and the second RFID tag carries second tag information. The first RFID tags on different cables carry different first tag information, and the second RFID tags on different ports 31 carry different second tag information.

[0059] Figure 6 shows the structure of an RFID tag 6 (the first and second RFID tags). The RFID tag may include, but is not limited to, an RFID chip, an induction circuit, an LED light, and an outer protective layer. The outer protective layer can be customized in a variety of configurations, such as a sleeve, a hanging sheet, or an adhesive layer. Any configuration that meets practical requirements and protects the RFID tag is encompassed within this application. For ease of description, the LED light included in the first RFID tag may be referred to as the first LED light, and the LED light included in the second RFID tag may be referred to as the second LED light.

[0060] The passive RFID tag receives control signals from the RFID reader / writer 2 via an inductive circuit. Based on the induced current generated by the control signal, the tag drives the RFID chip to execute the command, for example, illuminating the LED. To ensure that the light from the illuminated LED is visible, making it easier for construction workers to spot it among other RFID tags, the first RFID tag is placed on the traceable cable 4 and the second RFID tag is placed on the port 31 using injection molding. The injection molding material used is transparent or translucent.

[0061] The RFID reader / writer 2 can read the first RFID tag on the traceable cable 4 to obtain first tag information and the second RFID tag on the port 31 to obtain second tag information through a contactless method or a long-distance wireless sensing method, and transmit the read first tag information and second tag information to the user terminal device via the communication module or the network device 5. The user terminal device is configured to display a preset wiring network topology map and, upon receiving the first tag information and the second tag information, associate and store the first tag information and the second tag information according to the preset wiring network topology map to obtain a cable management database for cable management.

[0062] In one embodiment, wiring management software can be installed in the user terminal device. The construction personnel input control information through the wiring management software. The user terminal device generates control instructions based on the control information and sends the control instructions to the RFID reader / writer through the communication module built into the RFID reader / writer 2 or the network device 5, so that the RFID reader / writer controls the RFID tag to perform corresponding operations according to the control instructions.

[0063] For example, if a cable fails, a construction worker can use a user terminal device to generate a control instruction based on the tag information of the first RFID tag on the cable, and send the control instruction to the first RFID tag on the cable through a network device. After receiving the control instruction, the first RFID tag on the cable lights up the first LED light, thereby displaying the location of the cable, allowing construction workers to quickly locate the cable and replace it in a timely manner. After replacing the new cable, the construction worker uses an RFID reader / writer device to send a control instruction to the new cable based on the tag information on the RFID tag on the new cable. The new cable lights up according to the control instruction, facilitating confirmation by the construction worker.

[0064] In one embodiment, an audible and visual device such as a buzzer may be used to display the status and position of the RFID tag according to the control instruction.

[0065] It should be understood that during the production process, the RFID tag needs to have its tag information written. Due to the limited storage space of the RFID tag, the RFID tag in this application only serves to identify and locate the port 31 and the traceable cable 4. Therefore, once the tag information is written, it will not be modified.

[0066] Compared with the cable management system in the prior art, the radio frequency identification-based cable management system 1 provided in the embodiment of the present application does not require the setting of a monitoring host and a management unit, nor does it require the setting of a PCB board in each port 31 of the distribution frame 3, thereby reducing hardware costs, eliminating the process of configuring lines for the management unit, and reducing wiring costs and difficulty.

[0067] Furthermore, the network equipment 5, patch panels 3 (optical patch panels 3, copper patch panels 3), traceable cables 4 (traceable optical cables and traceable copper cables), user terminal equipment, and power supply equipment provided in this embodiment of the application do not require special customization, nor does it require additional power to the patch panels 3, thereby reducing energy consumption in the computer room or cabinet. Furthermore, the RFID tags are passive and do not require additional power, further reducing energy consumption in the computer room or cabinet.

[0068] There is no need for connecting lines between each port 31 of the distribution frame 3, and interaction is carried out through wireless communication. Therefore, the complexity can be greatly reduced and work efficiency can be improved in actual wiring construction or management and maintenance. By setting an RFID tag on the port 31 and the traceable cable, and reading the tag information of the RFID tag through an RFID reader / writer, the port 31 and the traceable cable can be quickly associated based on the tag information, thereby improving management efficiency. By adding a first LED light to the RFID tag to display the status and position of the RFID tag, construction personnel can quickly locate the port and cable. The following describes the process of using an RFID-based cable management system for cable management in conjunction with Figure 7.

[0069] Figure 7 is a flow chart of a cable management method based on radio frequency identification provided in an embodiment of the present application. The cable management method based on radio frequency identification includes the following steps.

[0070] S71, the user terminal device displays a preset wiring network topology diagram.

[0071] The user terminal device can download the preset wiring network topology map from the server and display the preset wiring network topology map upon receiving an opening instruction from the construction personnel. The preset wiring network topology map is a pre-set guide map used to indicate the location and connection relationship of devices in a computer room or cabinet during networking. It shows the physical connection mode, transmission path, and logical relationship between different devices in the network (e.g., switches, routers, servers, etc.).

[0072] The preset wiring network topology diagram is used to guide construction personnel in arranging equipment and cables in a computer room or cabinet, and is used to guide construction personnel in locating faulty equipment or cables when troubleshooting and repairing the computer room or cabinet.

[0073] The preset wiring network topology diagram is designed before construction. If the preset wiring network topology diagram is to be displayed on a user terminal device, a visual interface needs to be created on the server, and the format of the preset wiring network topology diagram is converted through the visual interface. When required, construction personnel download the converted wiring network topology diagram from the server through the user terminal device.

[0074] S72: When a traceable cable is connected to a port of a distribution frame, the user terminal device obtains first tag information of a first radio frequency identification tag set on the traceable cable.

[0075] The traceable cables are connected to the ports of the distribution frame by construction workers. For example, the construction workers connect the traceable optical cables to the ports of the optical distribution frame and the traceable copper cables to the ports of the copper distribution frame.

[0076] The first RFID tag can be attached to the traceable cable at the factory, and then the installation personnel can connect the traceable cables with the first RFID tag to the ports of the patch panel one by one. Alternatively, the installation personnel can attach the first RFID tag to the traceable cable while laying out the cables in the equipment room or cabinet, and then connect the traceable cables with the first RFID tag to the ports of the patch panel one by one after the installation is completed.

[0077] In one embodiment, the user terminal device obtains the first tag information of the first radio frequency identification tag set on the traceable cable, including: the user terminal device obtains the first tag information through a radio frequency identification reader / writer device or a network device, and the first tag information is obtained by reading the first radio frequency identification tag through the radio frequency identification reader / writer device.

[0078] When a construction worker inserts a traceable cable into a port of a patch panel, the RFID reader / writer can read the first tag information of the first RFID tag on the traceable cable and send the read first tag information to the user terminal device or the network device. When the RFID reader / writer sends the read first tag information to the network device, the user terminal device obtains the first tag information from the network device.

[0079] In one embodiment, a port insertion detection function can be set between the RFID reader and the port of the patch panel. When a traceable cable is inserted into a port of the patch panel, the RFID reader can detect that the traceable cable is inserted into the port.

[0080] In one embodiment, the user terminal device acquiring the first tag information of the first radio frequency identification tag set on the traceable cable includes: the user terminal device identifying the first radio frequency identification tag set on the traceable cable to obtain the first tag information.

[0081] When the construction personnel insert the traceable cable into the port of the patch panel, they can identify the RFID tag set on the traceable cable through the wireless sensing and identification function of the user terminal device to obtain the first tag information of the RFID tag.

[0082] In one embodiment, the first tag information can be obtained conveniently and accurately by reading with a radio frequency identification reader or writer, or by identifying with a user terminal device, thereby improving the efficiency of obtaining the first tag and avoiding input errors caused by human error.

[0083] S73: The user terminal device associates and stores the first tag information of the traceable cable and the second tag information of the second RFID tag on the corresponding port according to the preset wiring network topology to obtain a cable management database.

[0084] Storing the first tag information of the traceable cable and the second tag information of the corresponding second RFID tag on the port in association with each other refers to pairing the traceable cable with the port.

[0085] It should be noted that before wiring is completed, the second RFID tag on the port is associated with the port location identifier and stored in the server. The port location identifier and the second tag information of the second RFID tag are displayed in the wiring network topology diagram. This allows the user terminal device to clearly display the location identifier of the port on the patch panel and the second tag information of the corresponding second RFID tag.

[0086] In one embodiment, the user terminal device associates and stores the first tag information of the traceable cable and the second tag information of the second radio frequency identification tag on the corresponding port according to the preset wiring network topology map to obtain the cable management database, including: the user terminal device receives the first tag information and the second tag information confirmed by the construction personnel according to the preset wiring network topology map, associates and stores the first tag information and the second tag information, and obtains the cable management database.

[0087] Before connecting a traceable cable to a port, the construction personnel may bring the traceable cable close to an RFID reader / writer device, read the first tag information of the first RFID tag on the traceable cable through the RFID reader / writer device, and then send the first tag information read by the RFID reader / writer device to the user terminal device through the communication module or network device built into the RFID reader / writer device. The user terminal device displays the first tag information sent by the communication module or network device built into the RFID reader / writer device, and the construction personnel match and confirm the displayed first tag information with the second tag information of the second RFID tag on the port to be inserted.

[0088] After receiving the confirmation instruction from the construction worker, the user terminal device associates the first tag information with the corresponding second tag information and stores it in the cable management database.

[0089] In one embodiment, the user terminal device associates and stores the first tag information of the traceable cable with the second tag information of the second radio frequency identification tag on the corresponding port according to the preset wiring network topology map, and obtaining the cable management database includes: the user terminal device receives multiple first tag information sent by the communication module built into the radio frequency identification reader / writer device or the network device, and associates and stores the second tag information of the port with the corresponding first tag information according to the order of the position identifiers of the ports in the preset wiring network topology map and the order of receiving the multiple first tag information, to obtain the cable management database.

[0090] Construction workers can first connect multiple traceable cables to multiple ports and then use an RFID reader to identify the first tag information on these cables. Since different ports are located at different distances from the RFID reader, the RFID reader can send the identified first tag information to user terminals in order of distance via the RFID reader's built-in communication module or network device. The user terminals then match the first tag information with the port location identifiers in the pre-set wiring network topology diagram, based on the order in which the first tag information is sent (or received). This pairing order is pre-determined based on the actual installation location of the RFID reader, which determines the order in which the first tag information is read.

[0091] The user terminal device associates and stores the paired second tag information and the corresponding first tag information in the cable management database in sequence.

[0092] In one embodiment, the user terminal device may upload the cable management database to the server for storage, so that subsequent maintenance personnel can maintain the cables in the computer room or cabinet according to the cable management database.

[0093] In one embodiment, the method further comprises:

[0094] When the user terminal device receives a search instruction for a designated traceable cable from a construction worker, the user terminal device obtains first label information of the designated traceable cable;

[0095] The user terminal device generates a first search control instruction according to the first label information of the designated traceable cable;

[0096] The user terminal device sends the first search control instruction to the radio frequency identification reader / writer device to control the radio frequency identification reader / writer device to search for the designated traceable cable according to the first search control instruction. The radio frequency identification reader / writer device searches for the designated traceable cable including controlling the designated traceable cable to light up.

[0097] Assuming that a construction worker clearly identifies the traceable cables that require repair, that is, specifies which cable or cables require repair, but due to the large number of cables, the construction worker cannot quickly locate the traceable cables that require repair. In this case, the construction worker can input the target first tag information of the specified traceable cable into the user terminal device, triggering the user terminal device to generate a first search control instruction including the first tag information of the specified traceable cable. The RFID reader / writer awakens the first RFID tag corresponding to the specified traceable cable according to the first search control instruction and obtains feedback information from the first RFID tag of the specified traceable cable. After receiving the feedback information from the first RFID tag of the specified traceable cable, the RFID reader / writer sends a lighting control instruction to the first RFID tag of the specified traceable cable to control the first RFID tag of the specified traceable cable to light up.

[0098] In one embodiment, the method further comprises:

[0099] When the user terminal device receives a search instruction for all traceable cables from the construction personnel, it obtains the first tag information of all traceable cables;

[0100] The user terminal device generates a second search control instruction according to the first label information of all traceable cables;

[0101] The user terminal device sends the second search control instruction to the radio frequency identification reader / writer device to control the radio frequency identification reader / writer device to search all traceable cables according to the second search control instruction. The radio frequency identification reader / writer device searches for all traceable cables including controlling the traceable cables that are not faulty among all traceable cables to light up.

[0102] If a construction worker is unsure of which traceable cable or cables are faulty, they can trigger a user terminal device to traverse each first tag in the cable management database based on the first tag information and corresponding second tag information, port location identifiers, and other information stored in the cable management database. After traversing all first tag information, a second search control instruction is generated that includes all first tag information. The RFID reader / writer awakens the first RFID tags on all traceable cables based on the second search control instruction and obtains feedback from the awakened first RFID tags. Based on the feedback, the RFID reader / writer sends a lighting control instruction to the awakened first RFID tags to control them to light up. Unawakened first RFID tags will not light up due to a fault. This allows construction workers to repair the unawakened first RFID tags or update them with new traceable cables.

[0103] In one embodiment, by using a radio frequency reader to confirm the identity of a target radio frequency identification tag, the target cable can be quickly located, maintenance and debugging time can be shortened, and stable operation of equipment in a computer room or cabinet can be ensured.

[0104] In one embodiment, to achieve intelligent visual management, the server can update the preset cabling network topology diagram based on the cable management database to obtain a three-dimensional spatial simulation device management model to achieve visual management of cables and devices. The device management model includes the device location information, the second tag information of the device's corresponding port, the location information of the traceable cable, and the first tag information of the traceable cable.

[0105] In one embodiment, the server may also upload the wiring network topology diagram and the cable management database to the blockchain system for storage.

[0106] The radio frequency identification-based cable management system and method provided in the embodiments of the present application, in a computer room or cabinet where cables are densely distributed, by setting a first radio frequency identification tag on the cable and a second radio frequency identification tag on the port when the cable is arranged, when the construction personnel connect the cable to the port, the first tag information of the first radio frequency identification tag on the cable and the second tag information of the second radio frequency identification tag on the port can be established to obtain a cable management database. When the cable needs to be maintained or replaced subsequently, the position of the cable can be quickly located based on the cable management database. By setting an LED light in the radio frequency identification tag and controlling the lighting of the LED light in the radio frequency identification tag of the cable that needs maintenance or replacement through the radio frequency identification reading and writing device, the construction personnel can identify the cable at a glance among many cables, thereby helping to improve the convenience of cable finding.

[0107] The above are all optional embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
