Description

[0002] With the rapid development of rail transit, higher requirements are placed on the automation level and reliability of train onboard software updates. Due to the large number of onboard subsystems in trains, if manual updates are used, not only will the efficiency be low and the update time be long, but also the different technical qualities of different personnel may easily lead to software update failures or system failures, posing great security risks. In the face of the need for efficient and safe software upgrades, upgrading train onboard software through remote automatic updates has become one of the main methods of train operation and maintenance.

[0003] During the process of remote updating of on-board software, if there are abnormal situations such as power outages and unstable network, the software update may be incomplete or fail, making the train unable to operate normally. At present, in the field of rail transit, if the on-board software update of the train fails, it is necessary to manually upload the historical version for software recovery. However, there may be multiple running software versions on site, and it is necessary to manually confirm the software version or interact with the train to obtain the required historical version. The confirmation process is relatively cumbersome; and uploading historical versions will also increase the traffic consumption between the train and the ground, and prolong the update time.

These drawings and text descriptions are not intended to limit the scope of the present invention in any way, but to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0045] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0046] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0047] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0048] Figure 1 The following is a flow chart of a train onboard software upgrade method provided by an embodiment of the present invention. Figure 1 As shown, the train onboard software upgrade method provided in this embodiment can be applied to the train onboard terminal, and specifically may include:

[0049] S101. Obtain the software package to be upgraded from the ground server by wireless transmission. The software package to be upgraded includes upgrade script files of various historical versions of software. The upgrade script files include the local storage path, backup operation commands and backup storage path of each file in the corresponding version of software.

[0050] In this embodiment, the vehicle-mounted host can be used as follows Figure 2 The remote upgrade system shown is from the ground server, i.e. Figure 2 Obtain the software package to be upgraded from the software update server shown in . Figure 2 As shown, the train onboard software remote upgrade system may include a ground server (i.e. Figure 2The software update server shown in the figure), the vehicle host, the display and the vehicle subsystem, where the vehicle host includes RU300, WL300, SA300 and CN300. RU300 is the vehicle upgrade server, which is used to complete the automatic software update operation, including vehicle-ground identity authentication, secure connection, data interaction, security monitoring and security audit, etc.; WL300 is the wireless main control board, and the ground accesses the WIFI environment through WL300 after the train enters the depot; SA300 is the security protection board, which is configured with the vehicle-ground whitelist and protection strategy for the boundary security protection between the vehicle and the ground; CN300 is an Ethernet board, which is used for the host and external Ethernet communication and Ethernet communication between the boards in the chassis; the ground server deploys software upgrade monitoring software to monitor the connection, interaction and software upgrade process status of the vehicle-mounted equipment in real time, and supports the management of vehicle-mounted equipment software version and ground operator authority, etc.

[0051] When the software needs to be upgraded, the maintenance personnel clicks on the display interface and selects the specific subsystem software upgrade operation. The display sends the software upgrade command to RU300. After receiving the upgrade command, RU300 initiates identity authentication to the ground server through WIFI or 4G channel. After the identity authentication is successful, the vehicle-ground connection is established, and the vehicle-ground heartbeat state becomes idle. Then the software upgrade command is sent to the ground server. During the entire software upgrade process, RU300 will monitor the vehicle-ground communication content in real time by parsing the vehicle-ground protocol. For illegal connections or illegal operations in the connection, it will promptly warn and block the operation and record the log for analysis. The heartbeat state of the ground server and the vehicle host becomes the target code acquisition state. The ground server finds the specified target code file package according to the upgrade command and transfers the file package to the specified directory of RU300. After the transmission is completed, RU300 parses the software package, which contains a checksum file, and the checksum information in the file is encrypted using an asymmetric cipher. The checksum information in the checksum file is a summary value calculated by the device private key after the target code file is calculated by the SM3 algorithm. RU300 first uses the device public key to obtain the digest value plaintext, and then uses the SM3 algorithm to calculate the digest value of the target code file. If the two values ​​are equal, the target code is complete, otherwise it needs to be re-downloaded or the subsequent update process needs to be interrupted. The target code file in this embodiment is the software to be upgraded. After the software package to be upgraded is successfully obtained from the ground server, the heartbeat status of the ground server and the vehicle-mounted host changes to the subsystem update status. RU300 transmits the target code to the subsystem device. After the transmission is completed, RU300 sends the target code verification code to the subsystem, and the subsystem needs to return the verification result. If the verification fails, RU300 returns that the update failed.

[0052] It should be noted that although the train includes multiple on-board subsystem devices, in this embodiment, a communication connection is established only through the on-board host and the ground server, thereby avoiding security risks caused by communication between each on-board subsystem device and the ground server.

[0053] The software package to be upgraded includes upgrade script files of each historical version of the software, and the upgrade script file includes the local storage path, backup operation command and backup storage path of each file in the corresponding version of the software. For example, if the software version of the software package to be upgraded is V5, and there are 4 historical versions of V1, V2, V3 and V4 before, the upgrade script files corresponding to V1, V2, V3 and V4 can be included in the software package to be upgraded of V5. Optionally, the upgrade script file can contain information such as the local storage path, backup operation command, backup storage path, version information, file checksum value, file size and update command of all files of this version of the software. Local storage path: indicates the storage path of the target code file on the board; backup operation command: indicates the operation command when making the target code file rollback software package; backup storage path: indicates the storage path of the target code file when it is used for rollback backup; version information: indicates the version information of the target code file; file checksum value: indicates the checksum value calculated by the SM3 algorithm for the target code file; file size: indicates the size value of the target code file; update command: indicates the operation command when making the target code file update.

[0054] S102: Obtain a target upgrade script file corresponding to the current software version of the train on-board device from the upgrade script files of each historical version of the software included in the software package to be upgraded.

[0055] The subsystem device parses the obtained software package to be upgraded, and obtains the target upgrade script file corresponding to the current software version of the train onboard device from the upgrade script files of each historical version of the software package to be upgraded. For example, the matching upgrade script file can be obtained according to the software version information.

[0056] S103, executing the backup operation commands in the target upgrade script file one by one to obtain the target code file from the local storage path, and storing it according to the backup storage path to generate a backup software package of the current software version of the train onboard equipment.

[0057] The software of train on-board equipment is generally composed of multiple files such as the main program, library files and configuration files. Therefore, by executing the backup operation commands in the target upgrade script file one by one, obtaining the target code file from the local storage path and storing it according to the backup storage path, a backup software package of the current software version of the train on-board equipment can be generated.

[0058] There may be multiple software versions at the on-board software update site of the train. In the prior art, the ground server needs to prepare the corresponding backup software version, and needs to query in advance or interact with the train to obtain the specific version on site, and upload the software to the on-board device. When the software is updated remotely, it is necessary to obtain the new version and the backup version at the same time, which takes a long time to transmit and increases the risk of target code abnormality. Compared with the prior art, this embodiment compiles an upgrade script file for each historical version of the software, and before upgrading the on-board software of the train, first finds the upgrade script file of the corresponding version according to the current software version information, and then automatically backs up the current software version according to the script. The ground server does not need to prepare all software versions, which reduces the process of uploading backup version files. The risk of target code damage during transmission is reduced by automatically packaging and generating backup versions locally, and the traffic consumption and overall update time of vehicle-to-ground transmission are reduced.

[0059] S104: using the software package to be upgraded to update the software of the train onboard equipment.

[0060] After completing the automatic backup of the current software version, the software package to be upgraded can be used to update the software of the train onboard equipment. Specifically, the subsystem equipment can find the new version script file and execute the update commands in the upgrade script file one by one to update each target code file. After the update is completed, the board reset is automatically triggered or the on-site personnel are promoted to reset the board, and the heartbeat status of the ground server and the onboard host is changed to the version confirmation status.

[0061] S105, determining whether the software of the train onboard equipment is updated successfully, and if the update fails, using the backup software package to restore the software of the train onboard equipment.

[0062] In an optional implementation, the upgrade script file also includes update commands for each file in the corresponding version of the software. Using the backup software package to perform software recovery on the train onboard equipment may specifically include: executing the update commands in the target upgrade script file one by one to implement the rollback operation of each file in the backup software package.

[0063] The train on-board software upgrade method provided in this embodiment obtains the software package to be upgraded from the ground server by wireless transmission, the software package to be upgraded includes the upgrade script files of each historical version of the software, and the upgrade script files include the local storage path, backup operation command and backup storage path of each file in the corresponding version of the software; obtains the target upgrade script file corresponding to the current software version of the train on-board device from the upgrade script files of each historical version of the software included in the software package to be upgraded; executes the backup operation commands in the target upgrade script file one by one to obtain the target code file from the local storage path, and stores it according to the backup storage path to generate a backup software package of the current software version of the train on-board device; uses the software package to be upgraded to update the software of the train on-board device; determines whether the software of the train on-board device is successfully updated, and if the update fails, uses the backup software package to restore the software of the train on-board device. Automatically generating a backup software package locally in the train without manual participation reduces the transmission time and traffic consumption, and helps to improve the upgrade efficiency and reliability.

[0064] After the software upgrade fails, a backup software package needs to be used to perform a software rollback operation. So how to quickly determine whether the software of the train onboard equipment has been successfully updated? In an optional implementation, determining whether the software of the train onboard equipment has been successfully updated may specifically include: obtaining the software version information of the train onboard equipment after the update and the software version information of the software package to be upgraded; if the software version information of the train onboard equipment after the update is inconsistent with the software version information of the software package to be upgraded, it is determined that the software update of the train onboard equipment has failed. After the subsystem board is restarted successfully, if it is detected that the program is running, first query the subsystem program for the current software version information, and obtain the new version information from the local new version software package. If the two version information are inconsistent, it means that the update has failed and a software rollback operation is required.

[0065] However, even if the software version information of the train's onboard equipment is consistent with the software version information of the software package to be upgraded after the update, it cannot be 100% certain that the software update of the train's onboard equipment is successful. This is because onboard equipment in the rail transit field generally uses embedded systems, and there are many library files and configuration files in the train's onboard software. When a library file or configuration fails to update or is incomplete, the software may still be able to start, and only when it runs to a specific working condition will an abnormality occur. In other words, if some components or configuration files are incompletely updated or fail to update during the software update process, it will lead to the risk of abnormal software operation under some working conditions. It is impossible to accurately determine whether the software has been updated successfully through existing software process monitoring. In order to solve this problem, on the basis of the above-mentioned embodiments, in the train on-board software upgrade method provided by this embodiment, if the software version information of the train on-board equipment after the update is consistent with the software version information of the software package to be upgraded, it is determined whether the software of the train on-board equipment has been successfully updated, which can also specifically include: comparing the file size and file check code value of each file in the software of the train on-board equipment after the update with the file size and file check code value of the file in the software package to be upgraded one by one to see if they are consistent; if they are consistent, it is determined that the software update of the train on-board equipment is successful; otherwise, it is determined that the software update of the train on-board equipment has failed. In other words, only when each file in the software package to be upgraded is successfully updated can the software update of the train on-board equipment be determined to be successful. The method provided by this embodiment can accurately detect the situation where some files fail to update, and perform software rollback in time, which can effectively avoid the risk of abnormal software operation.

[0066] The train on-board software upgrade not only has high reliability requirements, but also has strict requirements for the upgrade time. This is because the time left for engineers at the upgrade site is often very limited, so reducing the upgrade time is of great significance. On the basis of any of the above embodiments, in order to further reduce the upgrade time, in the train on-board software upgrade method provided in this embodiment, the software of the train on-board equipment is updated using the software package to be upgraded, which can specifically include: for each file to be updated, judging whether the file size and file check code value of the current software of the train on-board equipment are consistent with those of the file in the software package to be upgraded; if they are consistent, the update operation is not performed on the file, and if they are inconsistent, the update operation is performed on the file. The software of the train on-board equipment is generally composed of a main program, a library file and a configuration file, and the library file is generally not updated. If the file size and file check code value of the current software of the train on-board equipment are consistent with those of a file in the software package to be upgraded, it means that the file has not been updated, and there is no need to perform the update operation, which can reduce the update time and reduce the risk of update failure.

[0067] In an optional implementation, before executing the backup operation commands in the target upgrade script file one by one to obtain the target code file from the local storage path, the method also includes: determining whether the software version information of the current software of the train onboard equipment is consistent with the software version information of the software package to be upgraded; if they are consistent, terminating the software upgrade process. If they are consistent, it means that the current software of the train onboard equipment is already the latest version and does not need to be updated. Terminate the software update process to avoid invalid updates. Furthermore, after terminating the software upgrade process, delete the software package to be upgraded stored in the train onboard equipment to release storage space.

[0068] To sum up, the train on-board software upgrade method proposed in the present application reduces the risk of target code damage during transmission by automatically packaging and generating backup versions based on the upgrade script files locally on-board, thereby reducing the traffic consumption and overall update time of train-to-ground transmission; the ground server does not need to prepare all software versions, which reduces the backup version file upload process and reduces the complexity of on-site update operations; further, the file size and file verification code value of each file in the train on-board equipment software after the update are compared one by one with the file size and file verification code value of the file in the software package to be upgraded, which can accurately detect the failure of some file updates, perform software rollback in time, effectively avoid the risk of software operation abnormalities, and improve the reliability of automatic software upgrades.
