The terms such as "upper", "inner", "middle", "left", "right" and "one" used in this specification are only used to facilitate the description and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship shall also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0025] Embodiment 1

[0026] like Figures 1-2 As shown, the device for identifying and matching device ports and cables described in the utility model includes an RFID reader / writer device 1. A first RFID tag 2 with a lighting function that can uniquely identify its port ID number is installed on each wiring port 4 of the device. A second RFID tag 3 with a light triggering function is installed on a cable 6 corresponding to each wiring port 4. The lighting of the first RFID tag 2 triggers the second RFID tag 3. The RFID reader / writer device 1 is used to activate, identify and match the first RFID tag 2 with the second RFID tag 3.

[0027] Among them, the first RFID tag 2 includes a first antenna, a first tag chip and a light emitting device. The first antenna and the light emitting device are electrically connected to the first tag chip respectively. The first tag chip receives or transmits radio frequency signals through the first antenna, and controls the light emitting device to emit light signals according to signal instructions. The light emitting device can be an LED lamp.

[0028] The second RFID tag 3 includes a second antenna, a second tag chip and an optical signal sensing and detection device. The second antenna and the optical signal sensing and detection device are electrically connected to the second tag chip respectively. The optical signal sensing and detection device senses the optical signal emitted by the optical emitting device and converts it into an electrical signal, thereby triggering the second tag chip to send tag information including the ID number to the RFID reading and writing device. The second tag chip receives or transmits the radio frequency signal through the second antenna.

[0029] Before the RFID reader / writer 1 activates the RFID tag, the RFID tag and physical port mapping method is first used to pre-store the identification code of the RFID tag and its corresponding wiring port number in the RFID reader / writer 1. For example, when applied to an optical cable junction box, each optical cable junction box is provided with a plurality of fiber splicing trays 8 above and below, each fiber splicing tray is configured with a plurality of wiring ports 4, and each wiring port 4 is marked with a unique identification ID, and the first RFID tag 2 is bound to the unique identification ID of the wiring port 4 and entered into the database.

[0030] The circuit working principle of this embodiment is as follows: each wiring port 4 of the device is installed with a first RFID tag 2 with a lighting function, and a second RFID tag 3 with a light triggering function is installed on the cable 6 connected to the wiring port 4; the identification code of the first RFID tag 2 can only uniquely identify a wiring port number, and the identification code of the first RFID tag 2 and the wiring port number corresponding to it are pre-stored in the RFID reading and writing device 1. The RFID reading and writing device 1 sends a wireless radio frequency identification signal to activate the first RFID tag 2 and the second RFID tag 3 nearby. According to the RFID anti-collision algorithm, the RFID reading and writing device 1 identifies the first RFID tag 2 on a wiring port 4 and lights up the LED light of the first RFID tag 2. The light emitted by the lit LED light triggers the second RFID tag 3 with a light triggering function on the cable 6 connected to the wiring port 4 identified above, so that the second RFID tag 3 on the cable 6 is uniquely identified by the RFID reading and writing device 1 at this time; the RFID reading and writing device 1 binds the two RFID tag identification codes on the wiring port 4 and the cable 6 read before and after one by one, thereby realizing the identification and matching of the wiring port 4 and the cable 6.

[0031] In order to better implement the device port and cable identification and matching apparatus described in this embodiment, the first RFID tag 2 is installed on the wiring port 4 through the port bracket 5, and the second RFID tag 3 is installed on the cable 6 through the cable 6 bracket.

[0032] like Figure 3-4 As shown, the port bracket 5 includes a port clamping portion 51 and a first label mounting portion 52 connected to each other. The clamping opening of the port clamping portion 51 is C-shaped, and the opening is clamped downward at the wiring port 4. The clamping opening of the port clamping portion 51 tightly clamps the wiring port 4, so that the port bracket 5 can be firmly installed on the wiring port 4. The first label mounting portion 52 can be designed to be plate-shaped and perpendicular to the port clamping portion 51. The first RFID tag 2 is installed at the bottom of the first label mounting portion 52, and can be specifically attached to the bottom of the first label mounting portion 52. Preferably, the two side edges of the bottom of the first label mounting portion 52 are provided with limit strips 53 along the plug-in direction of the cable 6, and the limit strips 53 are provided with limit grooves 54, so that the second label mounting portion 73 is conveniently inserted at the bottom of the first label mounting portion 52 along the length direction of the cable 6, so that the first RFID tag 2 is directly opposite to the second RFID tag 3, so that it is convenient for the LED light of the first RFID tag 2 to light up and trigger the second RFID tag 3 under the first label mounting portion 52.

In order to facilitate the easy installation of the kit 71 on the cable 6, a bayonet 75 is provided on the kit along the length direction of the kit. During installation, the bayonet 75 is aligned with the cable 6, and the kit 71 is clamped on the cable 6. In order to ensure that the kit 71 is firmly wrapped around the cable 6, a plurality of first limiting portions 72 that abut against the cable 6 can be provided around the opening of one end of the kit 71, and a second limiting portion 74 is provided at the opening of the other end to prevent the cable 6 from loosening in the kit. In this way, the kit 71 is sleeved on the cable 6 to clamp the cable 6, and ensure that the kit 71 is firmly installed on the cable 6. A second label mounting portion 73 is connected to the outer side of the kit 71. Specifically, the second label mounting portion 73 is arranged on the top of the kit 71 so that the second label mounting portion 73 corresponds to the position of the first label mounting portion 52. The second RFID tag 3 is mounted on the second label mounting portion 73. After the port bracket 5 and the cable bracket 6 are installed, the second label mounting portion 73 is directly opposite to the bottom of the first label mounting portion 52. Therefore, the second RFID tag 3 is also located directly below the first RFID tag 2, which facilitates the first RFID tag 2 to trigger the second RFID tag 3.

[0034] Preferably, the RFID reading and writing device 1 is fixed or handheld. The fixed RFID reading and writing device 1 is installed on the equipment, for example, on the optical cross-connection box or ODF rack. The handheld RFID reading and writing device 1 can be held in the hand of the staff. The RFID reading and writing device 1 activates the first RFID tag 2 and the second RFID tag 3 within the coverage range of its antenna, and performs batch scanning on the first RFID tags 2 installed on the wiring port 4 to determine whether there is a corresponding second RFID tag 3 installed on the cable 6 that is read. Then, it can be identified whether the corresponding wiring port 4 is occupied.

[0035] Embodiment 2

[0036] like Figures 1-2 As shown, the device for identifying and matching device ports and cables described in the utility model includes an RFID reader / writer device 1. A second RFID tag 3 that can uniquely identify the port ID number and has a light triggering function is installed on each wiring port 4 of the device. A first RFID tag 2 with a lighting function is installed on a cable 6 corresponding to each wiring port 4. When the first RFID tag 2 lights up, it triggers the second RFID tag 3. The RFID reader / writer device 1 is used to activate, identify and match the first RFID tag 2 and the second RFID tag 3.

[0037] Among them, the first RFID tag 2 includes a first antenna, a first tag chip and a light emitting device. The first antenna and the light emitting device are electrically connected to the first tag chip respectively. The first tag chip receives or transmits radio frequency signals through the first antenna, and controls the light emitting device to emit light signals according to signal instructions. The light emitting device can be an LED lamp.

[0038] The second RFID tag 3 includes a second antenna, a second tag chip and an optical signal sensing and detection device. The second antenna and the optical signal sensing and detection device are electrically connected to the second tag chip respectively. The optical signal sensing and detection device senses the optical signal emitted by the optical emitting device and converts it into an electrical signal, thereby triggering the second tag chip to send tag information including the ID number to the RFID reading and writing device. The second tag chip receives or transmits the radio frequency signal through the second antenna.

[0039] Before the RFID reader / writer 1 activates the RFID tag, the RFID tag and physical port mapping method is first used to pre-store the identification code of the RFID tag and its corresponding wiring port number in the RFID reader / writer 1. For example, when applied to an optical cable junction box, each optical cable junction box is provided with a plurality of fiber splicing trays 8 above and below, each fiber splicing tray is configured with a plurality of wiring ports 4, and each wiring port 4 is marked with a unique identification ID, and the second RFID tag 3 is bound to the unique identification ID of the wiring port 4 and entered into the database.

[0040] The circuit working principle of this embodiment is as follows: each wiring port 4 of the device is installed with a second RFID tag 3 with a light triggering function, and a first RFID tag 2 with a light-on function is installed on the cable 6 connected to the wiring port 4; the identification code of the second RFID tag 3 can only uniquely identify a wiring port number, and the identification code of the second RFID tag 3 and the wiring port number corresponding to it are pre-stored in the RFID reader-writer device 1. The RFID reader-writer device 1 sends a wireless radio frequency identification signal to activate the first RFID tag 2 and the second RFID tag 3 nearby. According to the RFID anti-collision algorithm, the RFID reader-writer device 1 identifies the first RFID tag 2 on a certain cable 6 and lights up the LED light of the first RFID tag 2. The light emitted by the lit LED light triggers the second RFID tag 3 with a light triggering function on the wiring port 4 connected to the cable 6 identified above, so that the second RFID tag 3 is uniquely identified by the RFID reader-writer device 1 at this time; the RFID reader-writer device 1 binds the two RFID tag identification codes on the wiring port 4 and the cable 6 read before and after one by one, thereby realizing the identification and matching of the wiring port 4 and the cable 6.

[0041] In order to better implement the device port and cable identification and matching apparatus described in this embodiment, the second RFID tag 3 is installed on the wiring port 4 through the port bracket 5, and the first RFID tag 2 is installed on the cable 6 through the cable 6 bracket.

[0042] like Figure 3-4 As shown, the port bracket 5 includes a port clamping portion 51 and a first label mounting portion 52 connected to each other. The clamping opening of the port clamping portion 51 is C-shaped, and the opening is clamped downward at the wiring port 4. The clamping opening of the port clamping portion 51 tightly clamps the wiring port 4, so that the port bracket 5 can be firmly installed on the wiring port 4. The first label mounting portion 52 can be designed to be plate-shaped and perpendicular to the port clamping portion 51. The second RFID tag 3 is installed at the bottom of the first label mounting portion 52, and can be specifically attached to the bottom of the first label mounting portion 52. Preferably, the two side edges of the bottom of the first label mounting portion 52 are provided with limit strips 53 along the plug-in direction of the cable 6, and the limit strips 53 are provided with limit grooves 54, so that the second label mounting portion 73 is conveniently inserted at the bottom of the first label mounting portion 52 along the length direction of the cable 6, so that the first RFID tag 2 is directly opposite to the second RFID tag 3, so that it is convenient for the LED light of the first RFID tag 2 to light up and trigger the second RFID tag 3 of the first label mounting portion 52.

[0043] like Figure 5-7 As shown, the cable 6 bracket includes a kit 71, the shape and size of the kit 71 are adapted to the cable 6, and the kit 71 is cylindrical and sleeved on one end of the cable 6 connected to the wiring port 4. In order to facilitate the easy installation of the kit 71 on the cable 6, a bayonet 75 is provided on the kit along the length direction of the kit. During installation, the bayonet 75 is aligned with the cable 6, and the kit 71 is clamped on the cable 6. In order to ensure that the kit 71 is firmly wrapped around the cable 6, a plurality of first limiting portions 72 that abut against the cable 6 can be provided around the opening of one end of the kit 71, and a second limiting portion 74 is provided at the opening of the other end to prevent the cable 6 from loosening in the kit. In this way, the kit 71 is sleeved on the cable 6 to clamp the cable 6, and ensure that the kit 71 is firmly installed on the cable 6. The outer side of the kit 71 is connected to a second label mounting portion 73. Specifically, the second label mounting portion 73 is arranged on the top of the kit 71 so that the second label mounting portion 73 corresponds to the position of the first label mounting portion 52. The first RFID tag 2 is mounted on the second label mounting portion 73. After the port bracket 5 and the cable bracket 6 are installed, the second label mounting portion 73 is directly opposite to the bottom of the first label mounting portion 52. Therefore, the first RFID tag 2 is also located directly below the second RFID tag 3, which facilitates the first RFID tag 2 to trigger the second RFID tag 3.

[0044] Preferably, the RFID reading and writing device 1 is fixed or handheld. The fixed RFID reading and writing device 1 is installed on the equipment, for example, on the optical cross-connection box or ODF rack. The handheld RFID reading and writing device 1 can be held in the hand of the staff. The RFID reading and writing device 1 activates the first RFID tag 2 and the second RFID tag 3 within the coverage range of its antenna, and performs batch scanning on the first RFID tags 2 installed on the cables 6 to determine whether there is a corresponding second RFID tag 3 installed on the wiring port 4 that is read. Then, it can be identified whether the corresponding wiring port 4 is occupied.

[0045] The utility model is applicable to scenarios where the wiring port 4 and the cable 6 need to be identified accordingly, for example, in an optical distribution network setting, the wiring port 4 is an optical distribution network port, the cable 6 is a jumper or a pigtail, the first RFID tag 2 / the second RFID tag 3 is installed on the optical distribution network port, and the second RFID tag 3 / the first RFID tag 2 is installed on the jumper or the pigtail.

[0046] For another example, on a network device, the wiring port 4 is a network port, the cable 6 is a network cable, the first RFID tag 2 / the second RFID tag 3 is installed on the network port, and the second RFID tag 3 / the first RFID tag 2 is installed on the network cable.

[0047] For another example, on an electric power device, the wiring port 4 is a wire interface, the cable 6 is a cable, the first RFID tag 2 / the second RFID tag 3 is installed on the wire interface, and the second RFID tag 3 / the first RFID tag 2 is installed on the cable.

[0048] The specific application scenarios are not limited to the above examples. Any scenario where such ports and cables 6 need to be identified can use the device port and cable identification and matching device described in the utility model. The device ports and cables 6 are matched one by one, and whether the device ports are occupied can be identified in time. During maintenance and changes, the port / cable that needs to be repaired or changed can be quickly found based on the correspondence between the device ports and cables 6, which greatly improves the operating efficiency of the staff and reduces the implementation cost. At the same time, because the utility model uses an RFID tag with a lighting function and light trigger, that is, there is contactless sensing between the two, relative to a contact sensing device, the utility model avoids the influence of dust and debris in the air, and ensures stable identification and matching performance of the device port and cable 6.

[0049] The implementation methods of the utility model are not limited to this. According to the above content of the utility model, by using common technical knowledge and customary means in the field, without departing from the above basic technical ideas of the utility model, the utility model can also make other various forms of modification, replacement or combination, all of which fall within the scope of protection of the utility model.
