[0047] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] Reference Figure 1 As shown, the method for upgrading the firmware of a visual navigation aid device according to an embodiment of the present invention includes:

[0049] S10. When detecting that the Bluetooth is in the on state, determine whether the Bluetooth is connected to the firmware upgrade device within a preset time; wherein the Bluetooth is provided on the visual navigation aid device, and when the visual navigation aid device is powered on, the Bluetooth is in the off state.

[0050] In this embodiment, the visual navigation aid device refers to navigation lighting equipment, such as runway edge lights, airport beacons, etc.; a control connection is always maintained between the visual navigation aid device and the server, and the server can control the light intensity adjustment, current adjustment, etc. of the visual navigation aid device. When the visual navigation aid device is powered on, the Bluetooth is turned off by default, and the server can issue a remote command to control the Bluetooth of the visual navigation aid device to turn on or off; wherein, the firmware upgrade device can be a mobile terminal device or a computer device, such as a tablet computer or a laptop computer, etc., and the staff can establish a connection with the visual navigation aid device through the firmware upgrade device within the Bluetooth range of the visual navigation aid device. After the server detects that the Bluetooth of the visual navigation aid device is turned on, the Bluetooth of the firmware upgrade device can be used to establish a connection with the Bluetooth of the visual navigation aid device, so that the server can determine whether the firmware upgrade device is connected to the visual navigation aid device within a preset time; optionally, the preset time can be set to 60 seconds.

[0051] S20: When the Bluetooth is not connected to the firmware upgrade device within a preset time, the Bluetooth is turned off.

[0052] In this embodiment, when the server detects that the Bluetooth connection between the firmware upgrade device and the visual navigation aid device is not established within the preset time, the server or the visual navigation aid device can control the Bluetooth of the visual navigation aid device to be automatically turned off, thereby making the visual navigation aid device safer; it can be understood that the preset time can be stored in the visual navigation aid device or in the server, thereby making the Bluetooth control of the visual navigation aid device simpler and more convenient.

[0053] S30: When the Bluetooth connection is established with the firmware upgrade device at the preset time, it is determined to upgrade the firmware program of the visual navigation aid device.

[0054] In this embodiment, when it is determined that Bluetooth and the firmware upgrade device are connected, the server determines that the visual navigation aid device firmware program can be upgraded. It can be understood that the firmware program upgrade refers to the upgrade of the embedded firmware of various machines, which can improve the machine function, enhance the machine stability, and patch the machine vulnerabilities; among them, OTA (Over The Air Upgrade) firmware upgrade can be used. The use of OTA firmware upgrade can enable the visual navigation aid device to be completed online without the need to back up data, and the upgrade efficiency is higher.

[0055] Preferably, before step S10, the method includes: when receiving an instruction from the visual navigation aid device requesting to turn on or off Bluetooth, turning on or off the Bluetooth.

[0056] In this embodiment, the firmware upgrade device is brought into the Bluetooth coverage area of ​​the visual navigation aid by the staff for fixed upgrade. For example, the visual navigation aid is set on the roof, and the staff can connect to the visual navigation aid downstairs. When the firmware upgrade device reaches the Bluetooth coverage range of the visual navigation aid, the server can receive an instruction sent by the firmware upgrade device requesting to turn on or off the Bluetooth of the visual navigation aid, so that the server controls the Bluetooth of the visual navigation aid to be turned on or off. It can be understood that the Bluetooth of the visual navigation aid can be quickly turned on or off by the server, or the Bluetooth of the visual navigation aid can be turned off when the Bluetooth of the visual navigation aid is not connected to the firmware upgrade device within the preset time, so as to avoid problems such as damage caused by invasion of the internal firmware of the visual navigation aid.

[0057] Reference Figure 2 As shown, the specific implementation of the above step S30 includes:

[0058] S301, when a Bluetooth connection is established with the firmware upgrade device, binding the first device identifier of the visual navigation aid device with the second device identifier of the firmware upgrade device;

[0059] S302: If the binding is successful, determine to upgrade the firmware program;

[0060] S303: If the binding fails, receiving prompt information for binding the first device identifier and the second device identifier;

[0061] S304, entering a modification interface for binding the first device identifier and the second device identifier according to the prompt information;

[0062] S305, generating a reset instruction input in the modification interface, and resetting the first device identifier according to the reset instruction;

[0063] S306: Bind the reset first device identifier and the second device identifier.

[0064] In this embodiment, the first device identifier may be an identifier such as a number or a device name of the visual navigation aid device. A plurality of different second device identifiers are stored in the firmware upgrade device, each of which has a corresponding first device identifier. When the Bluetooth of the visual navigation aid device is connected to the firmware upgrade device, the first device identifier and the second device identifier are used for binding, so that the firmware upgrade device can accurately bind to the visual navigation aid device that requires firmware upgrade to avoid connection errors. It can be understood that the connection status between the Bluetooth of the visual navigation aid device and the firmware upgrade device can be transmitted to the server. When the binding is successful, the server can determine that the firmware upgrade device can perform firmware upgrade on the visual navigation aid device. When the binding fails, the server generates a modification interface, so that a reset command can be input in the modification interface to reset the first device identifier of the visual navigation aid device. That is, the first device identifier of the visual navigation aid device can be modified to adapt to different regions. The reset command can reset the first device identifier to an initial state, and the first device representation in the initial state is used to establish a connection and bind with the firmware upgrade device. There are more optional methods and higher security.

[0065] Furthermore, the specific implementation of the above step S30 also includes:

[0066] When the firmware upgrade device establishes connections with multiple visual navigation aids, first device identifiers of the multiple visual navigation aids are obtained; and the multiple first device identifiers are output to the firmware upgrade device for binding.

[0067] In this embodiment, the firmware upgrade device can also be connected to the Bluetooth of multiple visual navigation aids at the same time. The server can establish a connection binding between the firmware upgrade device and the multiple visual navigation aids according to the one-to-one correspondence between the first device identifiers of the multiple visual navigation aids and the second device identifiers stored in the firmware upgrade device, so as to upgrade the firmware programs of the multiple visual navigation aids at the same time, thereby improving efficiency.

[0068] Preferably, when Bluetooth establishes a connection with a firmware upgrade device, determining to upgrade the firmware program also includes: when Bluetooth establishes a connection with the firmware upgrade device, determining an OTA upgrade data packet stored in the firmware upgrade device; based on the OTA upgrade data packet, downloading the OTA upgrade data packet and transmitting it to the visual navigation aid through the firmware upgrade device.

[0069] In this embodiment, the server can download the OTA upgrade data packet from the cloud and send it to the firmware upgrade device, so that when the firmware upgrade device is connected to the visual navigation aid device, the OTA upgrade data packet is sent to the visual navigation aid device for upgrading.

[0070] Reference Figure 3 As shown, the above step S30 includes:

[0071] S31, when the firmware program upgrade is completed, detecting whether the Bluetooth is disconnected from the firmware upgrade device;

[0072] S32, when the Bluetooth is disconnected from the firmware upgrade device, outputting a control command to the visual navigation aid device;

[0073] S33. Control the visual navigation aid to be powered on within a custom time according to the control instruction; the control instruction is used to trigger according to the custom time.

[0074] In this embodiment, after the firmware program upgrade of the visual navigation aid device is completed, the server checks the connection status of the Bluetooth of the visual navigation aid device and the firmware upgrade device. When in the disconnected state, the server can control the visual navigation aid device to turn on through control instructions, that is, to control the visual navigation aid device to emit light. The custom time can be any time, for example, it can be 0 seconds, that is, it can be turned on immediately, or it can be 5 seconds. By extending the turn-on time of the visual navigation aid device, it can be ensured that the visual navigation aid device is discharged and reset, and the controllability is better.

[0075] Reference Figure 4 As shown, the visual navigation aid device firmware upgrade device 40 according to an embodiment of the present invention includes:

[0076] The judgment module 401 is used to judge whether the Bluetooth is connected to the firmware upgrade device within a preset time when the Bluetooth is detected to be in the turned-on state; wherein the Bluetooth is provided on the visual navigation aid device, and when the visual navigation aid device is powered on, the Bluetooth is in the turned-off state;

[0077] The first shut-down module 402 is used to shut down the Bluetooth when the Bluetooth is not connected to the firmware upgrade device within a preset time;

[0078] The determination module 403 is used to determine to upgrade the firmware program of the visual navigation aid device when the Bluetooth connection is established with the firmware upgrade device at a preset time.

[0079] Furthermore, the firmware upgrade device 40 further includes:

[0080] The second closing module 404 closes the visual navigation aid device when a command requesting the visual navigation aid device to turn on Bluetooth is detected.
