Description

Technical Field

[0001] The present invention relates to the technical field of automobile log downloading, and in particular to a method and system for obtaining LOG logs based on U disk downloading. Background Art

[0002] Nowadays, more and more vehicles are equipped with some intelligent systems (commonly known as car computers), which will record the work logs related to some control modules or software inside the car, so that the staff can understand the working conditions of various modules and software inside the car through the logs.

[0003] In traditional LOG acquisition, car users are generally required to go to 4S stores, or vehicle maintenance personnel must obtain the vehicle's LOG information and corresponding LOG data through methods such as CAN bus and vehicle diagnosis.

[0004] This traditional way of working is not convenient for users, requires a certain amount of time and energy, and is relatively complicated to operate, and has certain technical requirements for users.

[0005] In view of the defects in the above background technology, we have designed a method and system for obtaining LOG logs based on USB flash drive download to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of traditional LOG log acquisition technology, such as complex and inconvenient operation, time-consuming and energy-consuming, and propose a method and system for obtaining LOG logs based on USB flash drive download. The method and system redefine the LOG log acquisition process and the communication mode between different hosts, thereby realizing the convenient LOG log acquisition work through USB flash drive.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A method for obtaining LOG logs based on USB flash drive download, comprising the following steps: Step S101: the user inserts a USB flash drive into the vehicle computer; Step S102: After the USB flash drive is connected, a "Get LOG" icon pops up on the Android interface, and the user clicks the "Get LOG" icon on the Android interface; Step S103: After the Android system captures the user clicking the "Get LOG" logo on the Android interface, it obtains the LOG instruction and sends a request to the Linux system to obtain the LOG; Step S104: After receiving the request for obtaining the LOG from the Android system, the Linux system transmits the LOG to the Android system in the form of a compressed package; In step S105, after the compressed package is transferred, a logo with the words "Copy to USB flash drive" pops up on the Android interface. The user clicks the logo with the words "Copy to USB flash drive" on the Android interface, and the Android system copies the compressed package to the USB flash drive.

[0008] Furthermore, in step S103 and step S104, the Android system and the Linux system communicate via the IPCL protocol; The Android system sends a LOG request to the Linux system through IPCL protocol communication. After receiving the LOG request, the Linux system packs the logs and generates a compressed package, and then feeds back to the Android system how many compressed packages are needed to complete the sending of the logs. The Android system receives the feedback, uses the IPC protocol to communicate, requests the log data in the form of a package number, and obtains the compressed packages of the log data in ID order until the last package is obtained.

[0009] Furthermore, the compressed packages of log data are obtained in order of ID. The data of each communication is serialized, and all data packets received by the Android system are grouped together as complete log content.

[0010] Furthermore, in step S104, after the Linux system receives the request for obtaining the LOG from the Android system, it transmits the LOG to the Android system in the form of a compressed package. The Android system sends a message to the Linux system through the vehicle computer. After receiving the LOG instruction, the Linux system packs the LOG to generate a compressed package and transmits it to the Android system through the IPC protocol.

[0011] Furthermore, in step S104, when the LOG is transmitted to the Android system in the form of a compressed package, the Android interface displays the transmission progress in the form of a progress bar or a rotating circle.

[0012] Furthermore, the compressed package refers to a LOG data packet compressed by the tar-xzf command.

[0013] Furthermore, in step S105, the Android system copies the compressed package of the log data to the USB flash drive using the following pre-acquisition mechanism: After the LOG log is downloaded to the Android system via the progress of steps S103 to S105, the user inserts a USB flash drive into the vehicle computer interface and directly copies the LOG through the USB flash drive to obtain the pre-acquisition mechanism.

[0014] Furthermore, the method for obtaining LOG logs based on U disk download includes obtaining the LOG logs of the single-chip microcomputer. The LOG logs of the single-chip microcomputer are transmitted to the Android system through the Linux system. The Android system packages the LOG logs of the three hosts, the single-chip microcomputer, the Linux system and the Android system, generates a compressed package, and finally copies the compressed package to the U disk.

[0015] A system for obtaining LOG logs based on USB download, characterized in that the system comprises: The command transceiver is deployed on the Android and Linux sides. It is used to send a request command to obtain the LOG to the Linux side and feedback the compressed package capacity required for sending the log once to the Android side. On the Android side, obtain the user's operation command, receive the LOG to compress the package file, and copy the compressed package to the USB flash drive; On the Linux side, after receiving the LOG request, the LOG log is packaged, a compressed package is generated, and the compressed package is transmitted to the Android side; The data storage end records and stores the LOG information sent by each application on the vehicle computer.

[0016] Furthermore, the instruction transceiver uses the IPCL protocol to communicate and send request instructions, sends a LOG request to the Linux end, and feeds back to the Android end how many compressed packages are needed to complete the sending of the log. After receiving the feedback, the Android end uses the IPC protocol to communicate and sends a request instruction for log data to the Linux end in the form of a package number; After receiving the request for obtaining LOG from the Android side, the vehicle sends a message to the Linux side through the vehicle computer. After receiving the LOG request instruction, the Linux side packs the LOG into a compressed package and transmits it to the Android side through the IPC protocol.

[0017] Compared with the prior art, the beneficial effects of the present invention are: through the downloading and acquisition of LOG logs proposed by the present invention, the vehicle computer LOG logs can be directly downloaded and acquired through a U disk, which has low requirements for wireless network signals, simplifies the log acquisition scenario, and the user only needs to issue an acquisition instruction throughout the process, and the rest of the acquisition process is automatic, which improves work convenience, has low requirements on user skills, is simple to operate, and saves work time and energy. DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] A method for obtaining LOG logs based on USB flash drive download, the method mainly includes the following steps: In step S101, the user inserts a USB flash drive into the vehicle computer, finds a USB interface on the vehicle computer, and inserts the USB flash drive.

[0020] In step S102, after the USB flash drive is connected to the vehicle computer, a logo with the words "Get LOG" will automatically pop up on the Android interface of the central control screen of the vehicle computer, and then the user can click the logo with the words "Get LOG" on the Android interface.

[0021] In step S103, when the user clicks the "Get LOG" icon on the Android interface, the Android system will capture the user clicking the "Get LOG" icon on the Android interface, and then automatically get the LOG instruction, and send a request to the Linux system to get the LOG.

[0022] In step S104, after receiving the request for obtaining the LOG sent by the Android system, the Linux system transmits the LOG to the Android system in the form of a compressed package.

[0023] The Android system sends a message to the Linux system through the vehicle computer. After receiving the LOG command, the Linux system packages the LOG to generate a compressed package and transmits it to the Android system through the IPC protocol.

[0024] In another implementation scenario, in order to more intuitively display the compressed package transmission progress, when the LOG is transmitted to the Android system in the form of a compressed package, the Android interface displays the transmission progress in the form of a progress bar or a rotating circle.

[0025] It is worth mentioning that in step S103 and step S104 of this embodiment, the Android system and the Linux system communicate through the IPCL protocol; specifically, the process of communicating through the IPCL protocol is as follows: The Android system sends a LOG request to the Linux system through IPCL protocol communication. After receiving the LOG request, the Linux system packages the log, compresses the LOG log data packet through the tar-xzf command, generates a compressed package, and feeds back to the Android system how many compressed packages are needed to complete the sending of the log.

[0026] The Android system receives the feedback, uses the IPC protocol to communicate, requests the log data in the form of a package number, and obtains the compressed packages of the log data in ID order until the last package is obtained.

[0027] What is special about the above is that when the compressed packages of log data are obtained in order of ID, the data of each communication is serialized, such as the first package, the second package, the third package... All data packets received by the Android system are grouped together as complete log content.

[0028] In step S105, after the compressed package is transferred, a "Copy to USB flash drive" icon will pop up on the Android interface. The user clicks the "Copy to USB flash drive" icon on the Android interface, and the Android system copies the compressed package containing the LOG information to the USB flash drive, completing the task of downloading the LOG log file from the vehicle using the USB flash drive.

[0029] In this step, the Android system copies the compressed package of the log data to the U disk using the following pre-acquisition mechanism: the LOG log is first downloaded to the Android system through the progress of steps S103 to S105, and then the user inserts the U disk into the USB interface of the vehicle computer, and directly copies the LOG through the U disk. In the pre-acquisition mechanism, the "Get LOG command" can be selected and issued in the form of an interface pop-up window.

[0030] As an embodiment, in this embodiment, the method for obtaining LOG logs based on U disk downloading also includes obtaining and downloading the MCU LOG logs based on U disk. The method is the same as the above-mentioned scheme process. The MCU LOG logs are transmitted to the Android system through the Linux system.

[0032] The command transceiver is deployed on the Android side and the Linux side, and is used to send a request command for obtaining LOG to the Linux side, and to feedback the compressed package capacity required for sending logs at a time to the Android side; the command transceiver uses the IPCL protocol to send and receive request commands, sends a LOG request to the Linux side, and feedbacks to the Android side how many compressed packages are required to complete the sending of the logs this time. After receiving the feedback, the Android side uses the IPC protocol to communicate and sends a request command for log data to the Linux side in the form of a package number; After receiving the request for obtaining LOG from the Android side, the vehicle sends a message to the Linux side through the vehicle computer. After receiving the LOG request instruction, the Linux side packs the LOG into a compressed package and transmits it to the Android side through the IPC protocol.

[0033] On the Android side, obtain the user's operation command, receive the LOG to compress the package file, and copy the compressed package to the USB flash drive; On the Linux side, after receiving the LOG request, the LOG log is packaged, a compressed package is generated, and the compressed package is transmitted to the Android side; The data storage end records and stores the LOG information sent by each application on the vehicle computer.

[0034] This embodiment also provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of the method for obtaining LOG logs based on USB flash drive download in the above embodiment can be executed. The specific implementation method can be found in the method embodiment, which will not be repeated here.
