[0046] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0047] The embodiment provided in this application is an embodiment of an over-the-air download system for an unmanned vehicle.

[0048] Combine the following Figure 1 The embodiments of the present application are described in detail.

[0049] An embodiment of the present application provides an over-the-air download system for an unmanned vehicle, including: an over-the-air download module 101 and a monitoring module 102 .

[0050] The over-the-air download module 101 is configured to download update data.

[0051] The monitoring module 102 is configured to: when the running state of the over-the-air download module is a non-running state, send a start instruction to the over-the-air download module to trigger the over-the-air download module to enter a normal running state.

[0052] The monitoring module may periodically (for example, every 5 seconds) check the running status of the over-the-air download module.

[0053] In the embodiment of the present application, the monitoring module is used to monitor the operating state of the over-the-air download module to ensure that the over-the-air download module is always in a normal operating state. If the operating state of the over-the-air download module is a non-operating state, the monitoring module sends a start instruction to enable the over-the-air download module to enter a normal operating state. Thus, the self-repair function of the unmanned vehicle is realized, the over-the-air download module is always in a normal operating state, the upgrade efficiency of the unmanned vehicle is improved, and the maintenance cost of the unmanned vehicle is reduced.

[0054] In some specific implementations, the system further includes a status query module 103 .

[0055] The monitoring module 102 is further configured to send a status query instruction of the over-the-air download module to the status query module.

[0056] The status query module 103 is configured to feedback the operating status of the over-the-air download module upon receiving a status query instruction of the over-the-air download module.

[0057] In this specific embodiment, the system further includes a status query module. After receiving the status query instruction of the over-the-air download module sent by the monitoring module, the status query module feeds back the operating status of the over-the-air download module to the monitoring module, so that the monitoring module can obtain the operating status of the over-the-air download module at any time, thereby determining whether to start the over-the-air download module to enter the normal operating state.

[0058] The monitoring module can periodically send the status query instruction of the air download module to the status query module so as to monitor the running status of the air download module; it can also send the status query instruction of the air download module to the status query module at any time as needed so as to monitor the running status of the air download module at any time.

[0059] In some specific implementations, the status query module is configured to feedback the operating status of the over-the-air download module when a status query instruction of the over-the-air download module is received, including: when a status query instruction of the over-the-air download module is received, obtaining all module information in normal operating state; when all module information in normal operating state includes module information of the over-the-air download module, feedback that the operating status of the over-the-air download module is a normal operating state; when all module information in normal operating state does not include module information of the over-the-air download module, feedback that the operating status of the over-the-air download module is a non-operating state.

[0060] In this specific embodiment, the status query module can obtain the module information of all normal operating states in the system. If the module information of all normal operating states includes the module information of the over-the-air download module, it indicates that the operating state of the over-the-air download module is a normal operating state; if the module information of all normal operating states does not include the module information of the over-the-air download module, it indicates that the operating state of the over-the-air download module is a non-operating state. In this way, the monitoring module can obtain the operating state of the over-the-air download module at any time, thereby determining whether to start the over-the-air download module to enter a normal operating state.

[0061] In some specific implementations, the monitoring module is configured to send a startup instruction to the air download module when the running state of the air download module is a non-running state, so as to trigger the air download module to enter a normal running state, including: when the running state of the air download module is a non-running state, continuously sending a startup instruction to the air download module, and sending a status query instruction of the air download module to the status query module after each sending of the startup instruction; when the number of consecutive sending of the startup instruction is greater than a preset failure number threshold, and the status query module feeds back that the running state of the air download module is a non-running state each time, updating the second update data of the current version in the air download module using the first update data of the saved current version; triggering the execution of the step of continuously sending a startup instruction to the air download module until the status query module feeds back that the running state of the air download module is a normal running state.

[0062] After sending the start command each time, a preset waiting time (e.g., 5 seconds) may be waited before sending the status query command of the air download module to the status query module, so that the status query module can enter a stable normal operation state, and the monitoring module can obtain the accurate operation state of the air download module. This avoids repeatedly sending the start command and causing excessive burden to the air download module, and ensures that the system can work efficiently.

[0063] In this specific embodiment, when the monitoring module finds that the running state of the air download module is in a non-running state, the air download module is repeatedly started until the air download module is started within the preset failure number threshold. If the air download module is not started within the preset failure number threshold, it indicates that the update data of the current version in the air download module has expired and the air download module cannot be started; the update data of the current version in the air download module is replaced with the pre-saved update data of the current version. Then the air download module is repeatedly started, and this is repeated until the air download module is started. In this way, the update data in the air download module is automatically repaired, ensuring that the running state of the air download module is always in a normal operating state, improving the upgrade efficiency of the unmanned vehicle, and reducing the maintenance cost of the unmanned vehicle.

[0064] In some specific implementations, the monitoring module is further configured to: when the operating state of the over-the-air download module is a non-operating state, read an upgrade flag; when the upgrade flag is a self-update flag, set the upgrade flag to a non-self-update flag.

[0065] In this specific embodiment, an upgrade flag is set. The upgrade flag is combined with the running state to determine whether to perform a version update. The running state and the upgrade flag should be consistent. If the running state of the air download module is a non-running state, the upgrade flag is a non-self-update flag. The upgrade flag enables the monitoring module and the air download module to act in a coordinated manner to avoid data conflicts.

[0066] In some specific implementations, the monitoring module is further configured to: when the operating state of the air download module is a normal operating state, read an upgrade flag; when the upgrade flag is a non-self-update flag, set the upgrade flag to a self-update flag.

[0067] In this specific embodiment, the running state and the upgrade flag should be consistent. If the running state of the over-the-air download module is a normal running state, the upgrade flag is a self-update flag.

[0068] In some specific implementations, the over-the-air download module is configured to download the update data, including: when the upgrade flag is a self-update flag, in response to receiving an upgrade message, downloading and saving the update data of a new version.

[0069] In this specific embodiment, if the upgrade flag is a self-update flag, it indicates that the over-the-air download module is allowed to download new update data. Then, when the over-the-air download module receives the upgrade message sent by the host computer, it can download and save the new version of the update data. This ensures the consistency of actions between the monitoring module and the over-the-air download module.

[0070] In some specific implementations, the over-the-air download module is further configured to: after downloading of the update data of the new version is completed, set the upgrade flag to a non-self-update flag; and enter the non-operating state when the upgrade flag is the non-self-update flag.

[0071] In this specific embodiment, after the update data download is completed, the over-the-air download module sets the upgrade flag to a non-self-update flag, and the over-the-air download module automatically exits the normal operation state, that is, stops running the over-the-air download module.

[0072] In some specific implementations, the monitoring module is configured to, when the running state of the air download module is a non-running state, before sending a startup instruction to the air download module, also include: when the running state of the air download module is a non-running state and the upgrade flag is a non-self-update flag, comparing the version information of the saved update data with the current version information of the update data in the air download module; when the version information of the saved update data is greater than the current version information of the update data in the air download module, using the saved update data to update the update data in the air download module.

[0073] When the running state of the over-the-air download module is a non-running state and the upgrade flag is a non-self-update flag, there are only two situations. The first situation is that the over-the-air download module encounters an accident and is in a non-running state. The second situation is that the over-the-air download module completes the download of the new version update data, automatically sets the upgrade flag to a non-self-update flag, and then enters a non-running state.

[0074] In this specific embodiment, the monitoring module first checks whether the data needs to be updated. When the version information of the saved update data is greater than the current version information of the update data in the air download module, it indicates that the update data in the air download module needs to be updated at this time, which belongs to the second case. Therefore, after the update data in the air download module is updated, a start instruction is sent to the air download module. This realizes the self-update process of the unmanned vehicle, improves the upgrade efficiency of the unmanned vehicle, and reduces the maintenance cost of the unmanned vehicle.

[0075] In some specific implementations, the monitoring module is further configured to: in response to detecting a power-on signal of the unmanned vehicle, delete log information that exceeds a preset day threshold.

[0076] In this specific embodiment, each time the vehicle is powered on, the log files generated by the system are automatically cleaned up, and only the log information within the preset number of days is retained. This prevents the log file data from being too large, occupying the chip memory, and affecting the operating efficiency of other systems. It ensures that the system can efficiently implement data update tasks. At the same time, retaining log information for a certain period of time can help maintenance personnel quickly find fault information and improve maintenance efficiency.

[0077] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0078] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
