Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
Example 1
The intelligent operation of the engineering mechanical equipment relates to a plurality of application programs, and when the configuration files of some application programs need to be updated iteratively, the new and old versions of the application programs should be smoothly switched, so that the normal operation of the engineering mechanical equipment cannot be influenced. The embodiment 1 of the invention discloses an OTA upgrading method which can be used for iterative updating of intelligent operation application programs of engineering mechanical equipment. Fig. 1 is a flow chart of an OTA upgrading method in embodiment 1 of the present invention, and as shown in fig. 1, the OTA upgrading method in embodiment 1 of the present invention includes the following steps:
s101: and when receiving the upgrade instruction of the software, acquiring the upgrade version software.
As a specific implementation manner, the following scheme may be adopted for obtaining the upgrade version software: the cloud service platform stores various update packages with different versions, and an OTA server (an upgrade server on the cloud service platform) pushes upgrade notification messages to corresponding equipment terminals at random; an OTA Manager (upgrade Manager on equipment) analyzes own requirements and sends a notification message for downloading the upgrade version software to a cloud, wherein the notification message comprises identification information of the software and current version information of the software; the equipment gateway downloads the upgrade version software from the cloud service platform in a wireless communication transmission mode; and the upgrade manager acquires the upgrade version software downloaded in the cloud from the equipment gateway through a communication network carried in the equipment.
S102: the upgrade version software is installed in a different partition than the current version software.
As a specific implementation manner, before installing the upgrade version software in a partition different from the current version software, the upgrade manager first obtains an area where the current version software is installed, and then the upgrade manager searches for an additional installation area for the upgrade version software. Specifically, the electronic control unit of the engineering machinery equipment is required to support the partitioning of hardware or software, such as an area A and an area B, wherein isolation exists between the area A and the area B, and software programs running in the respective areas do not affect each other, but can perform data interaction.
In embodiment 1 of the present invention, installing the upgrade version software in a different partition from the current version software can avoid the upgrade version software from covering the current version software, and cause the running service in the current version software to be interrupted before the upgrade version software is not completely established.
S103: and synchronizing the service related data of the current service of the current version software to the upgrading version software.
In embodiment 1 of the present invention, the service-related data includes one or more of the following: memory data (i.e., current service data stored in memory), unprocessed data (i.e., portion of the data that is unprocessed by the current service), and configuration files.
This is because if the current service data in processing is cached in the memory of the system, restarting the current service in the updated version software will result in the loss of the current service data stored in the memory, resulting in interruption of the current service, and thus the current service data stored in the memory, i.e., the memory data, needs to be synchronously processed.
In addition, if the current service data is already stored in the database, if the unprocessed portion of the current service is not synchronized to the upgrade version software, the current service process may be restarted in the upgrade version software, which may also result in loss of the unprocessed portion of the current service, resulting in interruption of the current service.
In embodiment 1 of the present invention, the configuration file is related to data in the service process, such as configured port number, IP address, and the like. It should be noted that in some cases, the configuration file is not included in the current service running process, and in the case that the configuration file is not included, the configuration file does not need to be synchronized.
As a specific implementation manner, the following scheme may be adopted to synchronize the memory data to the upgrade version software: determining a memory corresponding to the current version of software; and acquiring the memory data from a memory corresponding to the current version software and synchronizing to the updated version software. That is to say that the first and second,
As a specific embodiment, the synchronization of the unprocessed data to the upgrade version software may be performed in the following manner: determining an address of a database for holding the unprocessed data; when the address of the database is in the public area, acquiring an index of the unprocessed data, and sending the index to the upgrade version software; and when the address of the database is in a private directory area corresponding to the current version software, acquiring the unprocessed data in the private directory area and synchronizing to the updated version software.
As a specific embodiment, the synchronizing the configuration file to the upgrade version software may adopt the following manner: determining an address of a database for storing the configuration file; when the address of the database is in the public area, acquiring an index of the configuration file, and sending the index to the upgrade version software; and when the address of the database is in a private directory area corresponding to the current version software, acquiring the configuration file in the private directory area and synchronizing to the updated version software.
It should be noted that, the steps S101 to S103 may be performed during the current service operation, or may be performed under other conditions; when steps S101 to S103 are performed during the execution of the current service, the interruption of the running service in the current version of software is not caused.
Therefore, in the OTA upgrading method provided by the embodiment of the invention, when an upgrading instruction is received, the upgrading version software is obtained and is installed in a partition different from the current version software, namely, the upgrading version software and the current version software are installed in a A, B partition mode, so that the service running in the current version software is not influenced; by synchronizing the service related data of the current service of the current version software to the upgrade version software, service interruption caused by loss of the service related data of the current service when the current service is restarted in the upgrade version software can be avoided. That is, the operation of data synchronization is introduced in the switching process of A, B areas in the OTA upgrading process of the device, so that the service related data of the current service can be synchronized in a lossless manner, the unprocessed current service in the upgrading process is not interrupted, thereby ensuring the smooth switching of the software version and enabling the service of the OTA device to be upgraded in a lossless manner.
As a further embodiment, before synchronizing the service related data of the current service of the current version software to the updated version software, the method further includes: when receiving a new service of the software, distributing the new service to the updated version software; acquiring the running state of the new service in the upgrade version software; judging whether the new service runs successfully in the upgrade version software according to the running state; and after the new service runs successfully in the upgrade version software, executing the step of acquiring the current service data and the static data of the current version software. Therefore, after the upgrade version software runs successfully, the data synchronization can be performed again, and the data synchronization is ensured
As a further embodiment, after synchronizing the service related data of the current service of the current version software to the updated version software, the method further includes: stopping the operation of the current service in the current version software and synchronously starting the operation of the current service in the upgrade version software.

This example takes the intelligent driving suite of the engineering machine as an example, where a software version needs to be upgraded from version 1.0 to version 2.0 when executing the cluster operation, to describe the smooth upgrade process. The software runs in the area A before upgrading, and the version number is 1.0; an OTA upgrade is now performed to upgrade the OTA to version 2.0; the cloud service platform side provides remote upgrade support by the OTA server, and the equipment side uniformly schedules upgrade tasks by the process of the OTA Manager.
As shown in fig. 2, the OTA upgrading method includes the following steps:
1. version 1.0 before upgrading operates in zone A;
2. the cloud service platform side prepares an upgrade package after receiving an upgrade request notification of the equipment side, creates an upgrade task and sends an upgrade instruction to the equipment side;
3. After the equipment receives the upgrading instruction, the Ethernet communication gateway of the equipment downloads a software package of version 2.0 from the cloud service platform side through a 5G network; after the downloading is completed, distributing and deploying the version 2.0 in the region B for operation through a CAN network OTA Manager carried by the equipment, and switching the new service to the version 2.0 of the region B for processing;
4. After confirming that the 2.0 version software of the B area runs successfully, the OTA Manager sends a data synchronization instruction to the 1.0 version of the A area, and the 1.0 version of the A area starts to synchronize configuration data, memory data, database data and the like and business related data to the 2.0 version of the B area;
5. after the data synchronization is completed, the OTA Manager stops the 1.0 version operation of the A area, and the 2.0 version of the B area processes the service data of the old version synchronization.
The embodiment 1 of the invention provides a method for switching over the smooth upgrading of OTA, which can realize uninterrupted upgrading of service through the smooth switching over of software version, thereby greatly enriching the use scene of OTA and promoting the vigorous development of intelligent networking of engineering machinery.
