[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0030] Example 1, reference Figure 1 , is an embodiment of the present invention, which provides a method for remotely accessing and controlling an unmanned logistics vehicle chip, comprising:

[0031] It should be noted that if Figure 1 As shown, the system is ready to initialize and perform user authorization, that is, the OTA management platform needs to be initialized first, including configuring system parameters, loading the stdlib library, etc. Then, the platform will authorize the user and determine the user's operating permissions; ordinary users can only remotely access and view the vehicle-side chip files, while administrators and super administrators have more operating permissions, including controlling system modules, deleting, copying, and moving vehicle-side chip files, etc.

[0032] Furthermore, tasks are assigned and commands are executed. That is, the OTA management platform will assign tasks to the vehicle-side OTA according to the user's operating permissions and requests. Tasks include accessing vehicle-side chip files, controlling system modules, executing custom commands, etc.; the vehicle-side OTA will generate specified system commands based on the task type, operation content and operation directory, and execute the command through the system() function; then, the vehicle status is evaluated and remote access is performed. The OTA management platform will judge the vehicle status to determine whether the vehicle is in a state where remote access is possible. If the vehicle is powered on, the vehicle-side chip files can be accessed remotely; if the vehicle is in a non-automatic operation state, system control and custom operations and other functions can be executed; the vehicle-side OTA will execute corresponding operation commands according to the vehicle status, and feedback the execution results to the OTA management platform.

[0033] Furthermore, the system is controlled by the feedback results. The vehicle-side OTA will integrate the execution results and feedback information into a json message in a specified format and send it to the OTA management platform via HTTPS. The OTA management platform will display the operation results and block status based on the feedback information, and conduct user permission review and vehicle status judgment to ensure the security and accuracy of system control.

[0034] Example 2, reference Figure 1-Figure 2 , is an embodiment of the present invention, which provides a method for remotely accessing and controlling an unmanned logistics vehicle chip, comprising:

[0035] S1: The system is ready to initialize and perform user authorization.

[0036] It should be noted that the unmanned logistics vehicle is equipped with an automatically running OTA program. By adding and calling the stdlib library in the OTA program, the standard library header file contains the most commonly used system functions in C and C++ languages, including program control functions, memory management functions, mathematical calculation functions, etc., so that the vehicle-side OTA can execute, such as viewing files, obtaining processes, stopping and starting programs, moving and copying files, etc. and obtaining command execution results; developers remotely issue commands to unmanned logistics vehicles through the OTA management platform, including viewing the contents of vehicle-side chip files, stopping or starting modules, deleting vehicle-side chip files, etc.; Figure 2 As shown in Part A, a new remote access module, system control module and custom command module are added, and the existing user permission module and vehicle status module are combined to build a front-end logic framework to improve the accuracy and security of command execution; a message sending and receiving solution combining MQTT and HTTPS is used to realize the data closed loop of operation task issuance and information result feedback, and to build an OTA management platform and a vehicle-side OTA information transmission mechanism.

[0037] Further, such as Figure 1 As shown in S1 in the figure, the OTA management platform has inconsistent operating permissions for different types of login accounts. The platform will first determine the user permissions. Ordinary users can only remotely access and view the vehicle-side chip files. Administrators can also control various modules of the system, including start and stop operations, and can also delete, copy, and move vehicle-side chip files. Super administrators can also customize operating system commands for remote execution.

[0038] Furthermore, Figure 2 As shown in Part A, the user permission module mainly implements the OTA management platform to review whether different types of users have the permission to execute this function. Ordinary users can only remotely access and view the vehicle-side chip files. Administrators can also control various modules of the system, including start and stop operations, and can also delete, copy, and move vehicle-side chip files. Super administrators can also customize operating system commands for remote execution.

[0039] S2: Assign tasks and execute commands.

[0040] It should be noted that if Figure 1 As shown in S2, after confirming the user authority and operation type, the OTA management platform confirms the status of the unmanned logistics vehicle. The remote access vehicle-side chip function can be executed as long as the vehicle is powered on, without vehicle status restrictions. Functions such as system control and custom operations require that the vehicle must be in a non-automatic running state before they can be executed.

[0041] Further, such as Figure 1 As shown in S3, after all restrictions are confirmed, the OTA management platform will send a task message containing information such as task type, operation content, and operation directory to the vehicle-side OTA through MQTT.

[0042] Furthermore, Figure 2 As shown in Part A, the system control module mainly implements the OTA management platform to operate the start, stop and restart operations of different modules of the vehicle-side unmanned logistics system, and displays the operation results and module status; the custom command module mainly implements the OTA management platform to send custom commands to the vehicle-side chip for execution, and displays the execution results.

[0043] S3: Assess vehicle status and perform remote access.

[0044] It should be noted that if Figure 1 As shown in S4, after the vehicle-side OTA receives the task, it generates the specified system command and calls the system function system() to execute it according to the task type, operation content, and operation directory.

[0045] Further, such as Figure 1As shown in S5, the vehicle-side OTA uses the two macros WIFEXITED and WEXITSTATUS that handle the exit status of the subprocess to determine whether the command is executed successfully, and extracts the information returned by the system after the command is executed successfully; Figure 2 As shown in Part B, the task execution module mainly implements the vehicle-side OTA calling the system command execution interface system() to execute the command generated in the previous step, and also judges whether the command execution is successful or not through the two macros WIFEXITED and WEXITSTATUS that handle the exit status of the sub-process.

[0046] Furthermore, Figure 2 As shown in Part A of , the remote access module mainly implements the OTA management platform to display the vehicle-side chip file structure and preview the file content, and processes the access-class json format message fed back by the vehicle-side OTA; the vehicle status module mainly implements the judgment of the vehicle status that needs to be remotely controlled. The remote access and viewing of the vehicle-side chip file functions can send commands to the vehicle-side OTA as long as the vehicle is powered on. The functions such as vehicle-side chip file operations, system control and custom operations require that the vehicle must be in a non-automatic running state before sending commands to the vehicle-side OTA; Figure 2 As shown in Part B, the flexibility of remote access control is increased through the mode of built-in operation commands plus customized operation commands, covering 90% of development requirements; a new HTTPS request interface is added, and the execution results and feedback information are integrated into a specified json format message and sent to the OTA management platform, realizing the front-end display of operation results function.

[0047] S4: Feedback the results to the system to obtain system control.

[0048] It should be noted that if Figure 1 As shown in S6, the vehicle-side OTA feeds back the execution results and information to the OTA management platform via HTTPS.

[0049] Further, such as Figure 2 As shown in Part B, a new task receiving module, task execution module and result feedback module are added to execute corresponding commands according to different functions, and extract execution results and feedback information; the task receiving module mainly implements the vehicle-side OTA to receive task messages sent by the OTA management platform, identify the message type, and confirm whether the task is a file access type, file operation type or module operation type. Different types take different branches to generate different operation commands; the result feedback module mainly implements the vehicle-side OTA to extract the information returned by the system after the command is executed, and integrates the execution results and feedback information into a json message in a specified format and sends it to the OTA management platform via HTTPS.

[0050] The above is a schematic scheme of a method for remotely accessing and controlling the chip of an unmanned logistics vehicle in this embodiment.
