Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The application online upgrade method of the present invention is described below with reference to fig. 1 to 3. The online upgrading method of the application program is executed by a processor or software and/or hardware in the processor. As shown in fig. 1, the method for upgrading an application program online of the present invention includes:
s101, reading the current values of all marks in an identification storage area when a bootstrap program is started, wherein the marks comprise an upgrading mark, a sending completion mark and a storage area mark; the upgrading mark is used for representing whether an upgrading file exists or not, and the sending completion mark is used for representing whether the upgrading file is sent completely or not; the storage area mark is used for representing a program backup area corresponding to the upgrade file or a program backup area corresponding to the current operating file; the upgrade file and the current operation file are respectively stored in different program backup areas.
Specifically, the current values of the upgrade flag, the transmission completion flag, and the storage area flag are stored in the identification storage area. The upgrade flag is used to represent whether an upgrade file exists, for example, if the upgrade flag is 0, it indicates that the upgrade file does not exist, and if the upgrade flag is 1, it indicates that the upgrade file exists. The sending completion flag is used for representing whether the sending of the upgrade file is completed or not, and the upgrade file is completely sent to a program operation area of the device to be upgraded, namely, the sending is completed, otherwise, the sending is not completed, for example, the sending completion flag is 0 to indicate that the sending is not completed, and the sending completion flag is 1 to indicate that the sending is completed. Among them, electronic devices such as controllers, computers, and the like, are devices to be upgraded. The storage area mark is used for representing a program backup area corresponding to the upgrade file or a program backup area corresponding to the current operating file. The upgrade file is a file used for upgrading the equipment to be upgraded, and the current operation file is a file which normally operates in the equipment to be upgraded before the equipment to be upgraded is upgraded through the upgrade file. The upgrade file and the current operation file are respectively stored in different program backup areas, the number of the program backup areas can be two, one is used for storing the current operation file, the other is used for storing the upgrade file, the two program backup areas can alternately store the upgrade file, for example, the current operation file is stored in the first program backup area, the upgrade file is stored in the second program backup area, if the equipment to be upgraded is successfully upgraded, the upgrade file is stored in the first program backup area when being received, otherwise, the upgrade file is still stored in the second program backup area when being received.
In addition, when the bootstrap program of the equipment to be upgraded is started, the equipment to be upgraded is upgraded, so that the normal work of the equipment to be upgraded is not influenced in the upgrading process, and the usability is high.
S102, when it is determined that preset conditions are met based on the current value of the upgrading mark and the current value of the sending completion mark, obtaining a file to be executed from the corresponding program backup area based on the current value of the storage area mark, sending the file to be executed to a program operation area of equipment to be upgraded, and updating the current value of the mark and operating the file to be executed in the program operation area; the file to be executed is the upgrade file or the current operation file.
Specifically, the preset condition may be set according to an actual requirement, for example, an upgrade task may exist. The upgrade task may be that an upgrade file exists and the upgrade file is not completely sent to the program operating area of the device to be upgraded, or that the upgrade file is completely sent to the program operating area of the device to be upgraded but the upgrade file fails to operate. For example, the upgrade flag is 1 and the transmission completion flag is 0, which indicates that the upgrade file exists and is not completely transmitted to the program running area of the device to be upgraded, if the upgrade file is downloaded and finishes waiting for upgrading, or the power is cut off when the upgrade file is not transmitted to the program running area of the device to be upgraded, or the power is cut off when the upgrade file is transmitted to the program running area of the device to be upgraded; the upgrade flag is 0 and the transmission completion flag is 1, which indicates that the upgrade file has been completely transmitted to the program operation area of the device to be upgraded but the upgrade file has failed to operate, i.e., the upgrade file itself has a problem and cannot operate.
When the preset condition is determined not to be met, the upgrading task does not exist, for example, the upgrading flag and the sending completion flag are both 0, and the current running file in the program running area can be directly guided to run.
And when the preset condition is met, acquiring the file to be executed from the corresponding program backup area based on the current value of the storage area mark, and copying the file to be executed to the program operation area to realize the operation of the file to be executed. When the upgrading is not executed, the current operating file is stored in the program operating area, and in the upgrading process, the upgrading file is sent to the program operating area so as to replace the current operating file in the program operating area through the upgrading file and complete the upgrading of the equipment to be upgraded.
When the upgrade file exists and is not completely transmitted to the program operating area of the equipment to be upgraded, the upgrade file can be copied to the program operating area from the program backup area corresponding to the upgrade file so as to upgrade the equipment to be upgraded, namely, when the equipment to be upgraded is powered on after power failure in the upgrading process, normal upgrading can still be carried out; when the upgrade file is completely sent to the program operation area of the equipment to be upgraded but the upgrade file fails to operate, the current operation file can be copied to the program operation area from the program backup area corresponding to the current operation file, so that when the upgrade file has a problem and the upgrade fails, the program can still be backed off, and the normal operation of the equipment to be upgraded is ensured.
After the file to be executed is sent to the program operation area of the device to be upgraded, the file to be executed in the program operation area is operated so as to detect whether the device to be upgraded can normally operate after the file in the program operation area is updated.
S103, if the file to be executed runs abnormally, the bootstrap program is started.
Specifically, if the to-be-executed file sent to the program running area of the to-be-upgraded device runs abnormally, it indicates that the upgrade fails, and the boot program is continuously started to execute step S101, and the to-be-executed file capable of running normally is reselected to ensure the normal running of the to-be-upgraded device. If the file to be executed sent to the program operation area of the equipment to be upgraded runs successfully, the equipment to be upgraded is restored to the state before upgrading after upgrading success or upgrading failure is indicated, and the equipment to be upgraded normally runs the file to be executed in the program operation area.
Therefore, when the boot program is started, the upgrading mark, the sending completion mark and the current value of the storage region mark in the identification storage region are read, whether the preset condition is met is determined based on the current value of the upgrading mark and the current value of the sending completion mark, the upgrading file or the current operating file is obtained from the corresponding program backup region according to the current value of the storage region mark when the preset condition is met and is sent to the program operating region of the equipment to be upgraded, the current values of all marks are updated, the file to be executed in the program operating region is operated, and the boot program is started when the file to be executed abnormally operates, so that the normal operation of the equipment to be upgraded can still be ensured when the self problem of the program or power failure abnormality occurs in the upgrading process.
Based on the above embodiment, when it is determined that the preset condition is satisfied, acquiring a file to be executed from the corresponding program backup area based on the current value of the storage area flag, sending the file to be executed to the program running area of the device to be upgraded, and updating the current value of the flag includes:
when the condition of normal upgrading is determined to be met, acquiring the upgrading file from the program backup area corresponding to the upgrading file based on the current value of the storage area mark, and sending the upgrading file serving as the file to be executed to the program operation area of the equipment to be upgraded;
and updating the current value of the upgrading mark and the current value of the transmission completion mark when the transmission of the file to be executed is determined to be completed.
Specifically, it is determined that a normal upgrade condition is met, that is, an upgrade file exists and is not completely transmitted to a program operation area of the device to be upgraded, if the upgrade file is downloaded and is waiting for upgrading, or the upgrade file is not transmitted to the program operation area of the device to be upgraded, and the power is cut off or the upgrade file is transmitted to the program operation area of the device to be upgraded; it may be determined that the normal upgrade condition is satisfied when the upgrade flag is 1 and the transmission completion flag is 0.
And when the normal upgrading condition is met, acquiring an upgrading file from a program backup area corresponding to the upgrading file based on the current value of the storage area mark, and sending the upgrading file serving as a file to be executed to a program operation area so as to upgrade the equipment to be upgraded. When the current value of the storage area mark is the program backup area corresponding to the upgrade file, the upgrade file can be directly obtained according to the current value of the storage area mark.
When the file to be executed is completely sent to the program running area of the equipment to be upgraded, updating the current value of the upgrade flag and the current value of the transmission completion flag, namely, the current value of the upgrade flag is updated to 0, and the transmission completion flag is updated to 1, which indicates that the current upgrade file is completely sent to the program running area of the equipment to be upgraded, and no new upgrade file exists.
Based on any of the above embodiments, when it is determined that the preset condition is satisfied, acquiring a file to be executed from the corresponding program backup area based on the current value of the storage area flag, sending the file to be executed to the program running area of the device to be upgraded, and updating the current value of the flag includes:
when the condition of upgrading failure is determined to be met, acquiring the current operating file from the program backup area corresponding to the current operating file based on the current value of the storage area mark, and sending the current operating file serving as the file to be executed to the program operating area of the equipment to be upgraded;
and updating the current value of the storage area mark to the program backup area corresponding to the current operating file.
Specifically, it is determined that an upgrade failure condition is met, that is, the upgrade file is completely sent to the program operation area of the device to be upgraded but the upgrade file fails to operate, if the upgrade file has a problem and cannot operate; it may be determined that the upgrade failure condition is satisfied when the upgrade flag is 0 and the transmission completion flag is 1.
When the upgrade failure condition is met, the current operating file is obtained from the program backup area corresponding to the current operating file based on the current value of the storage area mark, and the current operating file is sent to the program operating area as the file to be executed, so that when the upgrade failure occurs due to the problem of the upgrade file, the program can still be returned, and the normal operation of the equipment to be upgraded is ensured. When the current value of the storage area mark is the program backup area corresponding to the upgrade file, the program backup area of the upgrade file can be determined according to the current value of the storage area mark, and the current operating file is acquired through the other program backup area of the two program backup areas.
After the current operating file is sent to the program operating area, the current value of the storage area mark is updated to the program backup area corresponding to the current operating file, so that when the upgrade file is received next time, the program backup area for storing the upgrade file can be determined according to the current value of the storage area mark, and the current operating file and the upgrade file are ensured to be stored in different program backup areas.
Based on any of the above embodiments, when the boot program is started, reading current values of flags in the identifier storage area, where the flags include an upgrade flag, a transmission completion flag, and a storage area flag, and before the reading, the method further includes:
starting the current running file in the program running area;
when a program upgrading instruction is received, storing the upgrading file to the program backup area corresponding to the upgrading file;
and updating the upgrading mark to be used as an initial value of the upgrading mark when the upgrading file is determined to be stored completely.
Specifically, before upgrading the device to be upgraded, receiving an upgrade file. In the process of receiving the upgrade file, the current operation file in the program operation area is started, namely, the upgrade file is received online in the process of operating the current operation file so as to realize online upgrade, remote upgrade or local upgrade can be realized through online upgrade, the upgrade convenience is improved, and in the process of receiving the upgrade file, the normal operation of the equipment to be upgraded is not influenced.
In the process of operating the current running file, if a program upgrading instruction is received, the upgrading file is stored in the program backup area corresponding to the upgrading file, and when the upgrading file is completely stored in the program backup area corresponding to the upgrading file, the upgrading mark is updated, for example, the upgrading mark is updated from 0 to 1, so that when the bootstrap program is started, the existence of the upgrading file to be upgraded can be quickly and accurately determined according to the updated upgrading mark, and the timeliness and the effectiveness of the upgrading process are ensured.
Before updating the upgrade flag, the method further includes: the upgrade flag and the transmission completion flag are reset, for example, both the upgrade flag and the transmission completion flag are reset to 0, that is, it indicates that there is no upgrade task for the files in the program backup area, so that the upgrade flag of the newly received upgrade file can be updated to 1 after the upgrade file is stored in the corresponding program backup area, and the corresponding transmission completion flag is updated to 1 after the upgrade file is completely transmitted to the program operation area of the device to be upgraded, thereby the upgrade state can be determined quickly and accurately according to the upgrade flag and the transmission completion flag, and the reliability of the upgrade result is ensured.
Based on any of the above embodiments, the storing the upgrade file to the program backup area corresponding to the upgrade file includes:
reading the current value of the storage area mark;
determining the program backup area for storing the upgrade file based on the current value of the storage area flag, and updating the current value of the storage area flag to the program backup area for storing the upgrade file;
and storing the upgrade file to the program backup area corresponding to the current value of the storage area mark.
Specifically, in the process of determining the program backup area corresponding to the upgrade file, the current value of the storage area flag, that is, the program backup area corresponding to the current operating file operating in the program operating area, is read first, determining the program backup area corresponding to the current operating file according to the current value of the storage area mark, using the other one of the two program backup areas as the program backup area for storing the upgrade file, and updating the current value of the storage area mark into the program backup area corresponding to the upgrade file, so that the upgrade file and the current operating file are respectively stored in different program backup areas, and by updating the current value of the storage area flag in real time, in the upgrading process and the process of program rollback in upgrading failure, the file to be executed can be quickly and accurately determined, and the influence on the normal operation of equipment to be upgraded caused by upgrading and upgrading failure is avoided.
Based on any of the above embodiments, after the running the file to be executed in the program running area, the method further includes:
and if the file to be executed is successfully operated, updating the current value of the sending completion mark based on the current value of the sending completion mark.
Specifically, after a file to be executed in a program running area is run, if the file to be executed cannot be normally run, resetting the equipment to be upgraded; and if the file to be executed is the upgrading file, determining that the upgrading fails according to the upgrading mark and the sending completion mark when the equipment to be upgraded is reset, and acquiring the current running file to serve as the file to be executed. If the file to be executed is the current operating file, the fact that the current operating file obtained when the upgrading of the upgrading file fails is incorrect is indicated, the equipment to be upgraded is reset, and the current operating file is obtained again to serve as the file to be executed.
If the file to be executed can normally operate, which indicates that the upgrade is successful or the selection of the current operating file is correct, the current value of the sending completion flag is further updated by operating the file which can normally operate in the current program operating area, which indicates that the equipment to be upgraded can normally operate. The specific manner of updating the current value of the transmission completion flag based on the current value of the transmission completion flag may be set according to actual requirements, for example, when the current value of the transmission completion flag represents that the transmission of the upgrade file is completed, the transmission completion flag may be reset, that is, the current value of the transmission completion flag is reset to 0, or the current value of the transmission completion flag is updated to another value indicating that the upgrade is completed; when the current value of the transmission completion flag represents that the transmission of the upgrade file is not completed, the current value of the transmission completion flag may not be updated.
Based on any of the above embodiments, the updating the current value of the transmission completion flag based on the current value of the transmission completion flag includes:
and if the current value of the sending completion mark represents that the upgrading file is sent completely, updating the current value of the sending completion mark.
Specifically, if the to-be-executed file in the program running area of the to-be-upgraded device can run normally and the current value of the transmission completion flag represents that the transmission of the upgrade file is completed, which indicates that the to-be-upgraded device has executed the upgrade and the upgrade of the time is completed, the current value of the transmission completion flag may be updated from 1 to 0 to end the upgrade process, so that the upgrade can be executed normally when the upgrade file is received next time. If the file to be executed in the program operation area of the equipment to be upgraded can normally operate and the current value of the sending completion flag represents that the upgrading file is not sent completely, the upgrading is not executed on the equipment to be upgraded, and the sending completion flag does not need to be updated.
