[0001] This invention relates to the field of optical fiber technology, and in particular to plug and socket mating structures, methods, apparatuses, devices, storage media, and products. Background Technology

[0002] With the development of IoT technology, more and more scenarios are communicating through optical fibers. Quickly and efficiently completing the pairing of optical cable plugs and sockets has become a key focus of research and practice.

[0003] Currently, existing technologies integrate chips into the fiber optic plug and socket respectively, using methods such as direct insertion, optocoupler, and radio frequency coupling to detect the chip's pairing status, thereby determining the connection status of the plug and socket. However, the direct insertion method uses a pin header structure, and repeated insertion and removal can lead to spring fatigue and poor contact, resulting in poor stability. The optocoupler method is costly and susceptible to ambient light, causing false triggering. The radio frequency coupling method requires the addition of complete radio frequency transmitting and receiving modules and complex modulation and demodulation circuits, significantly increasing cost and complexity. Therefore, there is an urgent need for a low-cost, high-reliability, and low-complexity fiber optic plug and socket pairing structure. Summary of the Invention

[0007] The fiber optic connector includes a connector body and a second PCB board fixed to the connector body; the second PCB board integrates a second RFID antenna, a second RFID chip, a third metal layer, and a fourth metal layer; wherein the third metal layer is connected to the third pin of the second RFID chip; the fourth metal layer is connected to the fourth pin of the second RFID chip; the third metal layer and the fourth metal layer are located on the same plane;

[0008] Specifically, when the fiber optic plug is inserted into the fiber optic socket, the first metal layer and the third metal layer are perpendicularly aligned, and the second metal layer and the fourth metal layer are perpendicularly aligned; the first metal layer and the third metal layer are at a preset distance; the second metal layer and the fourth metal layer are at the preset distance.

[0009] According to another aspect of the present invention, a plug-socket pairing method is provided, applied to a reader / writer, comprising:

[0010] A preset pairing command is sent to the first RFID chip to trigger a first voltage difference between the first pin and the second pin;

[0011] The detection value of the second RFID chip is obtained, and it is determined whether the detection value is equal to a first preset value. If so, it is determined that the fiber optic socket and the fiber optic plug are in a paired state. The detection value is determined based on the voltage difference between the third pin and the fourth pin.

[0012] According to another aspect of the present invention, an electronic device is provided, the electronic device being configured as a reader / writer, the electronic device comprising:

[0013] At least one processor; and

[0014] A memory communicatively connected to the at least one processor; wherein,

[0015] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the plug and socket pairing method according to any embodiment of the present invention.

[0016] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the plug-socket pairing method according to any embodiment of the present invention.

[0017] According to another aspect of the present invention, a computer program product is provided, the computer program product comprising a computer program that, when executed by a processor, implements the plug and socket pairing method according to any embodiment of the present invention.

[0018] This invention provides a plug-and-socket pairing structure, comprising an optical fiber socket and an optical fiber plug. The optical fiber socket includes a socket body and a first PCB board fixed to the socket body. The first PCB board integrates a first RFID antenna, a first RFID chip, a first metal layer, and a second metal layer. The first metal layer is connected to a first pin of the first RFID chip, and the second metal layer is connected to a second pin of the first RFID chip. The first and second metal layers are located on the same plane. The optical fiber plug includes a plug body and a second PCB board fixed to the plug body.

This structure allows for capacitive coupling-based pairing detection of the fiber optic plug and socket. Compared to traditional RF coupling methods, this structure is simpler, eliminating the need for additional RF transceiver circuits and modulation / demodulation modules, significantly reducing chip power consumption. When the fiber optic plug is inserted into the socket, the first and third metal layers are perpendicularly aligned, as are the second and fourth metal layers, forming two sets of parallel-plate capacitors. This provides a foundation for signal transmission via induced charge using capacitive coupling, achieving non-contact pairing between the plug and socket. This avoids the contact problems caused by repeated insertion and removal in pin header direct-insertion structures, improving signal transmission reliability. Furthermore, compared to optical couplers, this structure uses induced charge for signal transmission, unaffected by optical signals, ensuring more stable and reliable pairing of the plug and socket. This broadens application scenarios and eliminates the need for expensive photodiodes, significantly reducing costs.

[0030] Example 1

[0031] Figure 1 This is a schematic diagram of a plug-socket mating structure provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where plugs and sockets are mated. Figure 1 As shown, the structure includes an optical fiber plug and an optical fiber socket, wherein: the optical fiber socket includes a socket body 100 and a first PCB board 101 fixed to the socket body; the first PCB board 101 integrates a first radio frequency identification (RFID) antenna 102, a first RFID chip 103, a first metal layer 104, and a second metal layer 105; wherein the first metal layer 104 is connected to a first pin of the first RFID chip 103; the second metal layer 105 is connected to a second pin of the first RFID chip 103; the first metal layer 104 and the second metal layer 105 are located on the same plane; the optical fiber plug includes a plug body 106 and a second PCB board 107 fixed to the plug body; the second PCB board 107 integrates a second RFID antenna. 108, a second RFID chip 109, a third metal layer 110, and a fourth metal layer 111; wherein, the third metal layer 110 is connected to the third pin of the second RFID chip 109; the fourth metal layer 111 is connected to the fourth pin of the second RFID chip 109; the third metal layer 110 and the fourth metal layer 111 are located on the same plane; wherein, when the fiber optic plug is inserted into the fiber optic socket, the first metal layer 104 and the third metal layer 110 are perpendicularly aligned, and the second metal layer 105 and the fourth metal layer 111 are perpendicularly aligned; the first metal layer 104 and the third metal layer 110 are at a preset distance; the second metal layer 105 and the fourth metal layer 111 are at the preset distance.

[0032] In this embodiment, a printed circuit board (PCB), i.e., a first PCB, can be fixed on the fiber optic connector. A first radio frequency identification (RFID) antenna, a first RFID chip, a first metal layer, and a second metal layer are integrated onto the first PCB. The first RFID antenna receives electromagnetic wave signals emitted by the reader (i.e., the RFID reader). The first RFID chip demodulates, decodes, and executes instructions on the electromagnetic wave signals. The first RFID antenna and the first RFID chip can be connected via pin soldering. The first and second metal layers can be etched from the metal layers on the first PCB (e.g., the copper layer covering the PCB surface), preserving the connection relationships between the first metal layer and the first pin, and between the second metal layer and the second pin. The first and second pins can be determined based on the chip specifications or circuit functions in the actual application scenario. Similarly, a second PCB can be obtained and fixed to the fiber optic connector.

[0033] For example, the metal layers of a PCB-based RFID tag can be engraved to create a first metal layer and a second metal layer. During engraving, the connection between the first metal layer and the first pin of the first RFID chip, and between the second metal layer and the second pin of the first RFID chip, are preserved, thus obtaining a first PCB board. The PCB-based RFID tag integrates an RFID antenna and an RFID chip. The integrated RFID antenna can be used as the first RFID antenna, and the integrated RFID chip can be used as the first RFID chip. Similarly, a second PCB board can be obtained. The first and second PCB boards are then fixed to an optical fiber socket and an optical fiber plug, respectively, ensuring that when the optical fiber plug is inserted into the optical fiber socket, the first and third metal layers, and the second and fourth metal layers, are perpendicularly aligned, forming two parallel plate capacitors. A preset distance is maintained between the first and third metal layers, and a preset distance is maintained between the second and third metal layers. This preset distance can be pre-set to a fixed value based on the gap between the optical fiber plug and the optical fiber socket.

[0034] like Figure 2As shown, when the fiber optic plug 202 is inserted into the fiber optic socket 201, the first metal layer 203 and the third metal layer 204, as well as the second metal layer and the fourth metal layer, are in a vertically aligned state, and there is a gap between the fiber optic plug and the fiber optic socket. Compared with the straight-pin header structure, the reliability of signal transmission will not be reduced due to mechanical wear during use, thereby improving the stability of the pairing detection of the fiber optic plug and the fiber optic socket.

[0035] Optionally, the dimensions of the first metal layer, the second metal layer, the third metal layer, and the fourth metal layer are preset dimensions. The area of ​​the preset dimensions is determined based on a first voltage difference, a preset distance, and the interlayer dielectric constant between the first and third metal layers. The first voltage difference is the voltage difference between the first pin and the second pin. The first voltage difference is used to induce a second voltage difference between the third and fourth pins through capacitive coupling. The advantage of this configuration is that determining the preset dimensions of the metal layers based on the first voltage difference, the preset distance, and the interlayer dielectric constant between the first and third metal layers avoids the blindness of empirical design. Furthermore, using the same dimensions for all four metal layers ensures a symmetrical and uniform electric field distribution, maintaining consistency in the amount of charge induced based on capacitive coupling, reducing signal fluctuations, and thus ensuring signal transmission stability. Additionally, using uniform preset dimensions for all four metal layers simplifies the production process and reduces production costs.

[0036] In this embodiment, when the fiber optic plug is inserted into the fiber optic socket, the first metal layer and the third metal layer form a parallel-plate capacitor, and the second metal layer and the fourth metal layer form a parallel-plate capacitor. To determine the area of ​​the four metal layers, the following expression can be used for calculation:

[0037] ;

[0038] in, The area representing the preset size. Represents the electrostatic constant. Represents the preset distance. This represents the amount of charge accumulated on the first metal layer. Represents the first voltage difference. This represents the interlayer dielectric constant between the first and third metal layers.

[0039] For example, the first voltage difference applied between the first and second pins is 1.8V. When a voltage difference of 0.3V or more is induced between the third and fourth pins, the second RFID chip can stably detect this voltage difference. The dielectric material of the first and second PCB boards is FR-4 with a dielectric constant of 4.4. The preset distance between the first and third metal layers is 0.5mm. Therefore, the preset area can be set to 50mm². 2 .

[0040] Optionally, the first voltage difference is generated upon triggering a preset pairing command issued by the reader. The advantage of this configuration is that triggering the generation of the first voltage difference via the preset pairing command sent by the reader enables precise control of the capacitive coupling process. Furthermore, the duration and amplitude of the first voltage difference can be flexibly adjusted based on the content of the preset pairing command, improving the applicability of this solution. The preset pairing command can utilize commands from the instruction set of the standard RFID protocol, eliminating the need for customized development and further reducing costs and enhancing applicability.

[0041] In this embodiment, the reader / writer can be an RFID reader / writer; the preset pairing command can adopt the SELECT command in the standard RFID protocol command set (e.g., ISO 15693 protocol). For example, the reader / writer transmits a SELECT command, which carries the identification information of the first RFID chip and the relevant flag information for setting the first voltage difference. After receiving the SELECT command, the first RFID chip generates a first voltage difference between its first and second pins, ensuring that a second voltage difference can be induced subsequently through capacitive coupling between the third and fourth pins of the second RFIC chip.

[0042] For example, such as Figure 3 As shown, a preset pairing command issued by the reader triggers a first voltage difference between the first pin 302 and the second pin 303 of the first RFID chip 301, causing charges of different polarities to accumulate in the first metal layer 304 and the second metal layer 305 respectively. Based on the principle of capacitive coupling, these charges will induce mirror charges of opposite polarities in the vertically opposite third metal layer 306 and fourth metal layer 307, thereby generating a second voltage difference between the third pin 308 and the fourth pin 309 of the second RFID chip 310, thus forming a complete signal transmission loop.

[0043] This invention provides a plug-and-socket pairing structure. A PCB board is fixed to the fiber optic plug and socket bodies respectively, and an RFID antenna, RFID chip, and metal layers are integrated into the PCB board. This structure allows for capacitive coupling-based detection of the pairing of the fiber optic plug and socket. Compared to traditional radio frequency coupling methods, the proposed structure is simpler, requiring no additional radio frequency transceiver circuits or modulation / demodulation modules, significantly reducing chip power consumption. When the fiber optic plug is inserted into the fiber optic socket, the first and third metal layers are perpendicularly aligned, and the second and fourth metal layers are also perpendicularly aligned, forming two sets of parallel-plate capacitors. This provides a foundation for signal transmission via induced charge using capacitive coupling, and achieves non-contact pairing of the fiber optic plug and socket, avoiding the contact problems caused by repeated insertion and removal in pin header direct-insertion structures, thus improving signal transmission reliability. Furthermore, compared to optical couplers, this structure uses induced charge to transmit signals, unaffected by optical signals, ensuring more stable and reliable pairing of the fiber optic plug and socket, expanding its application scenarios, and eliminating the need for expensive photodiodes and other components, significantly reducing costs.

[0044] Example 2

[0045] Figure 4 The flowchart of a plug and socket pairing method is provided in Embodiment 2 of the present invention. This embodiment is applicable to the pairing of plugs and sockets. The method is used to pair the fiber optic socket and fiber optic plug in the above-mentioned plug and socket pairing structure. The method can be executed by a plug and socket pairing device, which can be implemented in hardware and / or software. The plug and socket pairing device can be configured in an electronic device, which is configured as a reader / writer.

[0046] S401. Send a preset pairing command to the first RFID chip to trigger the generation of a first voltage difference between the first pin and the second pin.

[0047] In this embodiment, the preset pairing command may include the identification information of the first RFID chip and relevant flag information for setting the first voltage difference; taking the ISO 15693 protocol as an example, the preset pairing command may be a SELECT command. The first pin and the second pin can be determined according to the chip model. The first voltage difference is generally a low-voltage signal, and the specific value can be determined according to the chip performance.

[0048] For example, the reader sends a SELECT command, carrying the identification information of the first RFID chip and the relevant flag information for setting the first voltage difference. After receiving the SELECT command, the first RFID chip generates a first voltage difference between the first pin and the second pin. If the fiber optic plug is inserted into the fiber optic socket, the second RFID chip integrated in the fiber optic plug will induce a second voltage difference between the third pin and the fourth pin through capacitive coupling.

[0049] S402. Obtain the detection value of the second RFID chip, determine whether the detection value is equal to the first preset value, and if so, determine that the fiber optic socket and fiber optic plug are in a paired state; wherein, the detection value is determined based on the second voltage difference between the third pin and the fourth pin.

[0050] In this embodiment, the reader can obtain the detection value of the second RFID chip by sending a preset command to the second RFID chip. The detection value of the second RFID chip can be determined based on the second voltage difference between the third and fourth pins of the second RFID chip. The second voltage difference is the voltage difference induced by the capacitive coupling between the third and fourth pins. The pairing state can be understood as an optical fiber plug being inserted into an optical fiber socket. When it is determined that the optical fiber plug is inserted into the optical fiber socket, the correspondence between the identification information of the optical fiber plug and the identification information of the optical fiber socket can be recorded.

[0051] Optionally, before obtaining the detection value of the second RFID chip, the method further includes: broadcasting a preset detection voltage command to instruct the second RFID chip to detect the second voltage difference between the third pin and the fourth pin, and return a detection value; wherein, if the second voltage difference detected by the second RFID chip is greater than or equal to a preset voltage difference, the returned detection value is a first preset value; if the second voltage difference detected by the second RFID chip is less than the preset voltage difference, the returned detection value is a second preset value; the preset voltage difference is less than or equal to the first voltage difference. The advantage of this configuration is that the reader, by broadcasting the preset detection voltage command, instructs the second RFID chip to detect the second voltage difference between the third pin and the fourth pin and return a detection value. The preset detection voltage command can carry the identification information of multiple RFID chips, enabling directional control of multiple RFID chips, thereby improving the reader's detection efficiency for multiple RFID chips. The second RFID chip determines the returned detection value based on the relationship between the second voltage difference and the preset voltage difference, ensuring that the detection value reflects the current voltage difference between the third pin and the fourth pin, and guaranteeing that the reader can quickly determine whether the fiber optic plug and fiber optic socket are in a paired state based on the returned detection value.

[0052] In this embodiment, if the pairing status of a specific fiber optic plug (e.g., a fiber optic plug integrating a second RFID chip) with the current fiber optic socket is detected, the preset detection voltage command may include a preset voltage difference and the identification information of the second RFID chip. If the pairing status of multiple fiber optic plugs with the current fiber optic socket is detected, the preset detection voltage command may include a preset voltage difference and the identification information of the RFID chip corresponding to each fiber optic plug (e.g., specifying the range of identification information of the RFID chip that needs to be responded to). Since energy loss occurs during capacitive coupling, the preset voltage difference is less than or equal to the first voltage difference. The specific value can be set according to the chip performance or the actual application scenario. For example, when the fiber optic plug is inserted into the fiber optic socket, the second voltage difference induced between the third and fourth pins is measured. To avoid the influence of fluctuations in the value of the second voltage difference, the preset voltage difference can be set to a value less than or equal to the second voltage difference. The values ​​of the first preset value and the second preset value are different, and the first preset value and the second preset value can be preset. In addition, if it is determined that the fiber optic socket and the fiber optic plug are in an unpaired state (i.e., the fiber optic plug is not inserted into the fiber optic socket), a prompt message can be output to remind relevant personnel to check the current status of the fiber optic plug and the fiber optic socket, thereby improving the pairing efficiency of the plug and socket.

[0053] For example, taking the detection of pairing between a fiber optic socket and multiple fiber optic plugs as an example; the reader sends a preset pairing command carrying the identification information of the first RFID chip of the fiber optic socket and the relevant flag information for setting a first voltage difference, triggering the first RFID chip of the fiber optic socket to generate a first voltage difference between the first pin and the second pin; the reader broadcasts a preset detection voltage command carrying a preset tag range (the preset tag range is the value range of the identification information of the RFID chip integrated in the fiber optic plug) and preset voltage difference information, triggering the RFID chips of each fiber optic plug to detect a second voltage difference between the third pin and the fourth pin; if the second voltage... If the voltage difference is greater than or equal to a preset voltage difference, the first preset value is returned; if the second voltage difference is less than the preset voltage difference, the second preset value is returned. For example, for a certain fiber optic socket A, after the reader obtains the detection value returned by the RFID chip of each fiber optic plug, it determines whether each detection value is equal to the first preset value. If the detection value of fiber optic plug B is equal to the first preset value, it means that capacitive coupling has occurred between fiber optic plug B and fiber optic socket A, that is, fiber optic plug B and fiber optic socket A are in a paired state; if the detection value of fiber optic plug B is the second preset value, it means that capacitive coupling has not occurred between fiber optic plug B and fiber optic socket A, that is, fiber optic plug B and fiber optic socket A are in an unpaired state.

[0054] This invention provides a plug and socket pairing method. Based on the plug and socket pairing structure, a preset pairing command is sent to a first RFID chip to trigger a first voltage difference between the first and second pins. This allows the third and fourth pins of the second RFID chip to sense a second voltage difference through capacitive coupling, thereby enabling signal transmission. By acquiring the detection value of the second RFID chip, it is determined whether the detection value is equal to the first preset value. If so, it is determined that the fiber optic socket and the fiber optic plug are in a paired state. The detection value is determined based on the second voltage difference between the third and fourth pins. The detection value reflects the second voltage difference between the third and fourth pins, i.e., it reflects the pairing status between the fiber optic socket and the fiber optic plug, enabling this application to quickly and efficiently detect the pairing status of the fiber optic socket and the fiber optic plug.

[0055] Example 3

[0056] Figure 5 This is a flowchart of a plug-socket pairing method provided in Embodiment 3 of the present invention. Based on the above embodiments, this embodiment further determines whether the plug and socket are correctly paired according to the pairing status between them. Figure 5 As shown, the method includes:

[0057] S501. Send a preset pairing command to the first RFID chip to trigger the generation of a first voltage difference between the first pin and the second pin.

[0058] S502. Obtain the detection value of the second RFID chip, determine whether the detection value is equal to the first preset value, and if so, determine that the fiber optic socket and fiber optic plug are in a paired state; wherein, the detection value is determined based on the second voltage difference between the third pin and the fourth pin.

[0059] S503. Determine whether the pairing status matches the preset pairing status; if yes, execute S504; otherwise, execute S505.

[0060] The preset pairing status is determined based on the query results of the fiber optic socket's identification information in the preset pairing relationship database.

[0061] In this embodiment, the pairing status records the correspondence between the identification information of the current fiber optic socket and the identification information of the current fiber optic plug (i.e., the fiber optic plug inserted into the current fiber optic socket). The preset pairing status records the correspondence between the identification information of the current fiber optic socket and the identification information of the target fiber optic plug, where the target fiber optic plug can be understood as a fiber optic plug that has a pre-established binding relationship with the current fiber optic socket. A preset pairing relationship database can be pre-set, recording the correspondence between the identification information of the fiber optic socket and the identification information of the target fiber optic plug. The query result is the correspondence between the identification information of the current fiber optic socket and the identification information of the target fiber optic plug.

[0062] For example, determine whether the pairing status meets the preset pairing status. If it does, it means that the fiber optic plug inserted into the current fiber optic socket is the target fiber optic plug, and execute S504. If it does not, it means that the fiber optic plug inserted into the current fiber optic socket is not the target fiber optic plug, and execute S505.

[0063] S504. Determine that the fiber optic socket and fiber optic plug are correctly matched.

[0064] If the fiber optic plug inserted into the current fiber optic socket is the target fiber optic plug, it is determined that the current fiber optic socket and fiber optic plug are correctly paired; if the fiber optic socket and fiber optic plug are correctly paired, a pairing confirmation message can be output.

[0065] S505, The fiber optic socket and fiber optic plug are incorrectly matched.

[0066] If the fiber optic plug inserted into the current fiber optic socket is not the target fiber optic plug, it is determined that the current fiber optic socket and fiber optic plug are mismatched. If the fiber optic socket and fiber optic plug are mismatched, a warning message can be output to prompt relevant personnel to replace the fiber optic plug inserted into the current fiber optic socket.

[0067] In this embodiment, after determining that the fiber optic socket and the fiber optic plug are in a paired state, it is further determined whether the paired state conforms to the preset paired state, which further improves the detection scheme based on the plug and socket pairing structure and realizes efficient detection of the matching relationship between the fiber optic socket and the fiber optic plug.

[0068] Example 4

[0069] Figure 6 This is a schematic diagram of a plug-socket pairing device according to Embodiment 4 of the present invention. This device is applied to a reader / writer and is used to pair the fiber optic socket and fiber optic plug in the plug-socket pairing structure proposed in this application, such as... Figure 6 As shown, the device includes: a first voltage difference triggering module 601 and a socket plug pairing detection module 602.

[0070] The first voltage difference triggering module is used to send a preset pairing command to the first RFID chip to trigger the generation of a first voltage difference between the first pin and the second pin;

[0071] The socket-plug pairing detection module is used to obtain the detection value of the second RFID chip, determine whether the detection value is equal to a first preset value, and if so, determine that the fiber optic socket and the fiber optic plug are in a paired state; wherein, the detection value is determined based on the voltage difference between the third pin and the fourth pin.

[0072] This invention provides a plug and socket pairing device. Based on the plug and socket pairing structure, a preset pairing command is sent to a first RFID chip to trigger a first voltage difference between the first and second pins. This allows the third and fourth pins of the second RFID chip to sense a second voltage difference through capacitive coupling, thereby enabling signal transmission. By acquiring the detection value of the second RFID chip, it is determined whether the detection value is equal to the first preset value. If so, it is determined that the fiber optic socket and the fiber optic plug are in a paired state. The detection value is determined based on the second voltage difference between the third and fourth pins. The detection value reflects the second voltage difference between the third and fourth pins, i.e., it reflects the pairing status between the fiber optic socket and the fiber optic plug, enabling this application to quickly and efficiently detect the pairing status of the fiber optic socket and the fiber optic plug.

[0073] Optionally, the device further includes:
