[0038] This embodiment discloses a remote key debugging device, such as... Figure 1 As shown, the device is housed in a box composed of at least three flat panels 100, wherein any two flat panels 100 are connected and are adjacent to each other. The device includes:

[0039] The driver chip 102 is disposed in any planar board 100 and is used to send a first low-frequency drive signal when a control command is received;

[0040] Three low-frequency loop coils 103 are respectively disposed in the planar plate 100. The low-frequency loop coil 103 is used to apply a uniform magnetic field to the remote control key 12 when it receives the first low-frequency drive signal from the drive chip 102.

[0041] The signal receiver 104 is disposed in any flat plate 100 and is used to receive the high-frequency feedback signal emitted by the remote control key 12 under the action of a uniform magnetic field.

[0042] The controller 101 is disposed in any planar board 100. The controller 101 is connected to the driver chip 102 and the signal receiver 104 respectively, and is used to send control commands to the driver chip 102 or receive high-frequency feedback signals from the signal receiver 104.

[0043] In this embodiment, a uniform magnetic field is applied to the remote control key 12, and the feedback value of the remote control key 12 to the magnetic field is obtained. As a high-frequency feedback signal, the controller 101 determines whether the remote control key 12 is accurate by identifying whether the high-frequency feedback signal matches the strength value of the magnetic field. If the remote control key 12 is not accurate, the controller 101 can further activate the calibration function of the remote control key.

[0044] To make the remote key debugging device simple in structure and easy to use, in this embodiment, the remote key debugging device is set in a box, which contains at least three flat plates 100. The three flat plates 100 can form a cavity, in which the remote key 12 can be placed. A low-frequency loop coil 103 is installed in the flat plate. When the low-frequency loop coil 103 receives a drive signal, it can apply a uniform magnetic field to the remote key 12.

[0045] The remote control key debugging device is further equipped with a driver chip 102, a signal receiver 104, and a controller 101. The controller 101, driver chip 102, and signal receiver 104 can be installed on any flat panel 100. The driver chip 102 and signal receiver 104 can be installed on the same flat panel 100 or on different flat panels 100.

[0046] To activate a coil, such as the low-frequency loop coil 103, signals and energy need to be sent to it. The drive signal emitted by the driver chip 102 can activate the low-frequency loop coil 103 and begin applying a magnetic field. When the remote control key 12 receives the magnetic field, it can emit a high-frequency feedback signal. This high-frequency feedback signal can be captured by the signal receiver 104 and transmitted to the controller 101. The controller 101 can further analyze the high-frequency feedback signal to determine whether the accuracy of the remote control key 12 meets the requirements. In some embodiments, the high-frequency feedback signal can be a 433.27 MHz signal.

[0047] Compared to using Helmholtz coils as transmitting antennas, which have complex manufacturing processes, difficult-to-control winding precision, and poor stability in practical use, this method offers a more efficient solution. Furthermore, due to structural limitations, debugging equipment using Helmholtz coils is often complex, hindering installation and ease of use. The technical solution in this embodiment utilizes a toroidal coil, which is smaller than a Helmholtz coil and can be housed within a planar plate 100. By concentrating multiple planar plates 100 within a single enclosure, the size of the planar plates 100 can be reduced, resulting in a smaller overall space occupied by the remote control key debugging equipment. Additionally, the enclosure-style remote control key debugging equipment is easily movable and can be quickly put into use after relocation.

[0048] In some embodiments, the three planar plates 100 include: a first planar plate 1001, a second planar plate 1002 and a third planar plate 1003, and the three low-frequency loop coils 103 include: a first low-frequency loop coil 1031, a second low-frequency loop coil 1032 and a third low-frequency loop coil 1033.

[0049] A first region is provided in the first planar plate 1001, and a first low-frequency loop coil 1031 is fixed in the first region. The first low-frequency loop coil 1031 is used to apply a uniform magnetic field in the X-axis direction to the remote control key 12 when it receives a first low-frequency drive signal.

[0050] A second region is provided in the second planar plate 1002, and a second low-frequency loop coil 1032 is fixed in the second region. The second low-frequency loop coil 1032 is used to apply a uniform magnetic field in the Y-axis direction to the remote control key 12 when it receives the first low-frequency drive signal.

[0051] A third region is provided in the third planar plate 1003, and a third low-frequency loop coil 1033 is fixed in the third region. The third low-frequency loop coil 1033 is used to apply a uniform magnetic field in the Z-axis direction to the remote control key 12 when it receives the first low-frequency drive signal.

[0052] Low-frequency loop coils 103 are respectively arranged in three planar plates 100. In order to enable each low-frequency loop coil 103 to apply a uniform magnetic field in one direction to the remote control key 12, each of the three planar plates 100 is respectively arranged in the X-axis, Y-axis and Z-axis directions of the remote control key 12. Figure 2As shown, the planar plate 100 includes a first planar plate 1001, a second planar plate 1002, and a third planar plate 1003. After receiving a first low-frequency drive signal, the first low-frequency loop coil 1031 in the first planar plate 1001 applies a uniform magnetic field in the X-axis direction to the remote control key 12. After receiving the first low-frequency drive signal, the second low-frequency loop coil 1032 in the second planar plate 1002 applies a uniform magnetic field in the Y-axis direction to the remote control key 12. After receiving the first low-frequency drive signal, the third low-frequency loop coil 1033 in the third planar plate 1003 applies a uniform magnetic field in the Z-axis direction to the remote control key 12.

[0053] Using the technical solution of this embodiment, the three planar plates 100 that make up the box can respectively apply a uniform magnetic field to the remote control key 12, so that the remote control key 12 responds to the uniform magnetic field and emits a high-frequency feedback signal, thereby testing the signal response capability of the remote control key 12 in multiple dimensions.

[0054] In some embodiments, the housing further includes: a fourth planar plate 1004;

[0055] The fourth planar plate 1004 is connected to the first planar plate 1001 and the second planar plate 1002 respectively. The fourth planar plate 1004 is used as a platform for placing the remote control key 12. The fourth planar plate 1004 is used to support the first planar plate 1001, the second planar plate 1002 and the third planar plate 1003.

[0056] like Figure 3 As shown, in addition to the first planar plate 1001, the second planar plate 1002, and the third planar plate 1003, this embodiment also includes a fourth planar plate 1004. The fourth planar plate 1004 serves as a horizontal support plate for the entire remote control key debugging device 11, ensuring the working stability of the remote control key debugging device 11 and reducing the possibility of the remote control key debugging device 11 tipping over due to vibration or other factors. Furthermore, the fourth planar plate 1004 can also serve as a platform for placing the remote control key 12. By marking placement points for the remote control key 12 on the fourth planar plate 1004, the user can be instructed to place the remote control key 12 in a designated location, enabling the remote control key debugging device to quickly debug the remote control key 12.

[0057] In some embodiments, a shelf 105 is provided on the surface of the fourth planar plate 1004, and the shelf 105 is used to place the remote control key 12.

[0058] This embodiment also proposes that a shelf 105 be provided on the surface of the fourth planar plate 1004. In addition to indicating to the user to place the remote key 12, the shelf can also place the remote key 12 in a better position than directly placing the remote key 12 on the surface of the fourth planar plate 1004, so that the remote key 12 can be placed in a better position with a better magnetic field signal, and the high-frequency feedback signal emitted by the remote key 12 is better.

[0059] In some embodiments, the shelf 105 is provided with an anti-theft coil 1051;

[0060] When the second low-frequency drive signal is received from the driver chip 102, the anti-theft coil 1051 is connected to the remote key 12 and the controller 101. The anti-theft coil 1051 is used to obtain the identification code of the remote key 12 and send the identification code to the controller 101. The identification code serves as the start signal for the controller 101 to send the first low-frequency drive signal.

[0061] When the remote key 12 has a built-in anti-theft function, the anti-theft coil 1051 authenticates the remote key 12 through this function. Before applying a uniform magnetic field to the remote key 12, the driver chip 102 sends a second low-frequency drive signal through the anti-theft coil 1051 to obtain the identification code of the remote key 12 via a relevant protocol. This identification code is transmitted to the controller 101 through the signal receiver 104. Based on the identification code, the controller 101 controls the driver chip 102 so that the first low-frequency drive signal sent by the driver chip 102 enables the uniform magnetic field to establish a signal connection with the remote key 12, thus preventing the remote key 12 from being unable to be debugged due to its built-in anti-theft function.

[0062] In some embodiments, the remote key debugging device 11 further includes: a printed circuit board 106;

[0063] The printed circuit board 106 is fixed in any one of the first planar board 1001, the second planar board 1002, the third planar board 1003, and the fourth planar board 1004;

[0064] The printed circuit board 106 integrates at least a driver chip 102, a signal receiver 104, and a controller 101.

[0065] To facilitate the layout of electronic components, this embodiment proposes that a printed circuit board 106 be installed in the remote control key debugging device. The printed circuit board 106 integrates electronic components such as a controller 101, a driver chip 102, and a signal receiver 104. At the same time, in order to protect the printed circuit board 106, the printed circuit board 106 is installed in any one of the first planar board 1001, the second planar board 1002, the third planar board 1003, and the fourth planar board 1004, thereby ensuring the long-term and stable operation of the remote control key debugging device 11.

[0066] In some embodiments, a switch 107 is further provided on the surface of any one of the first planar plate 1001, the second planar plate 1002, the third planar plate 1003 and the fourth planar plate 1004. After the remote control key 12 is placed on the fourth planar plate 1004, the driver chip 102 responds to the start command of the switch 107 and sends a first low-frequency drive signal.

[0067] Switch 107 can be used as the start switch for remote key debugging device 11. After the remote key 12 is placed in the designated area on the fourth plane plate 1004 or the shelf 105, the user can control switch 107 to start the remote key debugging device 11, thereby enabling the remote key debugging device 11 to perform the anti-theft function authentication of the remote key 12, or to enable the controller 101 to send control commands to the driver chip 102.

[0068] In some embodiments, at least one display device 108 is further provided on the surface of any one of the first planar plate 1001, the second planar plate 1002, the third planar plate 1003 and the fourth planar plate 1004, and the display device 108 is connected to the controller 101.

[0069] The display device 108 is used at least to display the working process of the remote key debugging device 11. For example, the display device 108 can be a display screen 1082. When the controller 101 controls the driver chip 102 to drive the anti-theft coil 1051, the controller 101 can synchronously upload the control signal from the driver chip 102 to the display screen 1082. The display screen 1082 can display the controller 101 controlling the anti-theft function authentication. When the controller 101 sends a control command to the driver chip 102, the control command can be synchronously sent to the display screen 1082, and the display screen 1082 can show that the remote key debugging device 11 has started applying a uniform magnetic field to the remote key 12. When the controller 101 receives a high-frequency feedback signal, the display screen 1082 can display the value of the high-frequency feedback signal. By using the display screen 1082, the user can determine the specific working status of the remote key debugging device 11 and respond promptly to different working conditions.

[0070] For example, the display device 108 can also be an indicator light 1081. After the controller 101 receives a high-frequency feedback signal, the controller 101 identifies the magnetic field strength value detected by the remote key 12 and compares it with the magnetic field strength value of the magnetic field applied by the first low-frequency loop coil 1031, the second low-frequency loop coil 1032 or the third low-frequency loop coil 1033. The different differences between the two magnetic field strength values ​​can be displayed by displaying different colors.

[0071] In some embodiments, the remote key debugging device 11 further includes: a storage device 109;

[0072] The storage device 109 is connected to the controller 101. The storage device 109 stores storable information from the controller 101. The storable information is information generated by the controller 101 when processing high-frequency feedback signals.

[0073] When the remote control key 12 is subjected to a uniform magnetic field, it can send a high-frequency feedback signal. The signal receiver 104 receives this high-frequency feedback signal and transmits it to the controller 101. The high-frequency feedback signal includes the magnetic field strength value of the uniform magnetic field detected by the remote control key 12. The controller 101 can identify the magnetic field strength value detected by the remote control key 12 and compare it with the magnetic field strength values ​​applied by the first low-frequency loop coil 1031, the second low-frequency loop coil 1032, or the third low-frequency loop coil 1033. If the difference between the two magnetic field strength values ​​is too large, it is determined that the detection accuracy or precision of the remote control key 12 is insufficient, and the controller 101 can further perform calibration on the remote control key 12. After receiving the high-frequency feedback signal, the controller 101 can also upload the comparison results of the high-frequency feedback signal and the magnetic field strength value to the storage device 109, so that users can query the data through the storage device 109 even in non-real-time situations.

[0074] In another embodiment, the storage device 109 may also be a communication interface provided on the printed circuit board 106, through which a host computer can connect and perform data storage functions.

[0075] In some embodiments, this embodiment also discloses a remote control key 12, such as... Figure 4 As shown, the remote control key 12 is equipped with: a 3D inductor 121 and a high-frequency signal module 122;

[0076] The 3D inductor 121 is connected to the high-frequency signal module 122. When the 3D inductor 121 is affected by a uniform magnetic field, it outputs an inductance value. The high-frequency signal module 122 is used to generate a high-frequency feedback signal using the inductance value and to transmit the high-frequency feedback signal.

[0077] The remote key 12 is equipped with a 3D inductor 121. When it is in a uniform magnetic field in the X, Y and Z directions, the 3D inductor 121 can identify the magnetic field under the action of the uniform magnetic field in a certain direction. The inductance value of the inductor can be processed by the high-frequency signal module 122 to generate a high-frequency feedback signal and transmit it. For example, the high-frequency reflection signal can be a 433.27MHz reflection signal.

[0078] In addition, during the anti-theft function authentication, the driver chip 102 generates a second low-frequency drive signal. For example, the second low-frequency drive signal can be a 125K signal. The anti-theft coil 1051 is connected to the remote key 12 via the engine anti-theft lock method to obtain the identification code of the remote key 12. For example, the identification code can be an ID number, which can be transmitted in the form of a high-frequency feedback signal.

[0079] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
