The double-backup system equipment refers to embedded equipment with two sets of systems, and has the advantages of high system safety, and when one set of system is damaged, the other set of system can be used for starting and repairing the damaged system. The dual backup system device has the disadvantage of occupying more storage space because of storing two complete systems.
In the prior art, embedded devices have been cured as single backup system devices or dual backup system devices when shipped from the factory. With the use of the embedded device, the memory chip can be aged, the system in the memory chip is more easily damaged, and the single backup system device is easily unable to be started. With the upgrade of the embedded device system, the data volume of the system may increase, and the space of the memory chip of the dual-backup system device may be insufficient, which may cause the failure of the upgrade of the dual-backup system device system.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
First, terms in the present application will be explained:
Dual backup system: the system program is stored in two partitions, and when one partition data is abnormal, the system program can be started from the backup partition and the abnormal partition can be rewritten. In the case of dual system backups, the system program will occupy two partitions.
Upgrading: and the user directly performs maintainability upgrade on the system of the equipment through a web browser.
In the prior art, embedded devices have been cured as single backup system devices or dual backup system devices when shipped from the factory. Along with the use process of the embedded equipment, the storage chip can be aged, a system in the storage chip is more easily damaged, and the single backup system equipment is easily unable to be started. With the upgrade of the embedded device system, the data volume of the system may increase, and the space of the memory chip of the dual-backup system device may be insufficient, which may cause the failure of the upgrade of the dual-backup system device system.
In order to reduce the anomaly of the embedded device, the embodiment of the application provides an updating method of an embedded device system, which comprises the following steps:
Acquiring a system update package;
Analyzing the system update package to obtain a partition table file and system update data;
judging whether the system partition mode represented by the partition table file is the same as the current actual system partition mode;
If the partition table files are different, the system partition is divided again according to the system partition mode indicated by the partition table files, and a target system partition is obtained;
and according to the system updating data, completing the system updating of the target system partition.
In the embodiment of the application, the partition table file is added in the system update package, so that the system partition of the embedded device can be divided into the system partition modes represented by the partition table file, and the conversion of the embedded device between the single system partition and the double system partition can be realized. After the memory chip of the embedded equipment is aged, the embedded equipment is updated from a single system to double system backups, so that the situation that the embedded equipment cannot be started can be reduced. When the memory chip space of the embedded device is insufficient, the embedded device is updated from the double backup of the system to a single system, so that the condition that the system upgrade fails due to the insufficient memory space is reduced.
Referring to fig. 1, fig. 1 is a schematic flow chart of an updating method of an embedded device system according to an embodiment of the present application, where the method includes:
s11, acquiring a system update package.
The method for updating the embedded device in the embodiment of the application can be realized through the embedded device, and in particular, the embedded device can be a video camera, a hard disk video recorder, a spliced display and the like.
The embedded device may acquire the system update package through a wired or wireless manner, for example, may upload the system update package to the embedded device through a browser interface, or may import the system update package into the embedded device through the flash disk. The embedded device may also download the system update package from the server over the network.
S12, analyzing the system update package to obtain a partition table file and system update data.
The system update data is the data required by the system update, and the system update package comprises the partition table file in addition to the system update data. The partition table file indicates the number of system partitions, and for example, the partition table file may indicate a single system partition (system partition number of 1) or a double system partition (system partition number of 2). In addition, the partition table file may also include an identification of the system partition, such as a name or the like. The embedded device analyzes the system update package to obtain the partition table file and the system update data.
S13, judging whether the system partition mode represented by the partition table file is the same as the current actual system partition mode.
The system partition mode is single system partition or double system partition. The embedded device acquires the current actual system partition mode and compares whether the current actual system partition mode is the same as the system partition mode represented by the partition table file. If the system data are the same, the system data in the current actual system partition are updated directly by using the system update data.
S14, if the system partitions are different, the system partitions are re-divided according to the system partition mode indicated by the partition table file, and the target system partitions are obtained.
And under the condition that the system partition mode represented by the partition table file is different from the current actual system partition mode, the embedded device re-divides the system partition according to the system partition mode represented by the partition table file to obtain the target system partition.
For example, the current actual system partition mode of the embedded device is a dual system partition, that is, there are two system partitions, and the partition table file represents a single system partition, so that the embedded device merges the current two system partitions into one system partition, that is, the target system partition.
For example, the current actual system partition mode of the embedded device is a dual system partition, that is, one system partition is provided, and the partition table file represents the dual system partition, so that the embedded device divides the current one system partition into two system partitions, and the target system partition includes the two system partitions.
S15, completing the system updating of the target system partition according to the system updating data.
And using the system update data to complete the system update for the target system partition. For example, if the embedded device has one system partition, only the system partition needs to be updated. If the embedded device has two system partitions, the two system partitions are respectively updated.
In the embodiment of the application, the partition table file is added in the system update package, so that the system partition of the embedded device can be divided into the system partition modes represented by the partition table file, and the conversion of the embedded device between the single system partition and the double system partition can be realized. After the memory chip of the embedded equipment is aged, the embedded equipment is updated from a single system to double system backups, so that the situation that the embedded equipment cannot be started can be reduced. When the memory chip space of the embedded device is insufficient, the embedded device is updated from the double backup of the system to a single system, so that the condition that the system upgrade fails due to the insufficient memory space is reduced.
In one possible implementation manner, the system partition mode represented by the partition table file is a dual-system partition, and the current actual system partition mode is a single-system partition; referring to fig. 2, S14, if different, re-dividing the system partition according to the system partition mode indicated by the partition table file to obtain a target system partition, including:
S141, if the two system partitions are different, dividing the two system partitions according to the partition table file to obtain a target system partition, wherein the target system partition comprises a first system partition and a second system partition.
When the partition table file represents a dual-system partition, and the current actual system partition mode of the embedded device is a single-system partition, one system partition of the embedded device needs to be divided into two system partitions, namely a first system partition and a second system partition, wherein the first system partition and the second system partition are collectively called as a target system partition.
The step S15 of completing the system update of the target system partition according to the system update data, includes:
and S151, performing system updating on the first system partition according to the system updating data to obtain updated system data.
The identification of the first system partition is the same as the identification of the system partition before division, for example, the partition names are the same, and the device upgrade logic installs the program of the system update data into the first system partition according to the update logic of the single backup system.
And S152, copying the updated system data in the first system partition into the second system partition.
After the system data in the first system partition is updated, the updated system data in the first system partition is copied to the second system partition, so that the system update of the whole target system partition is completed.
The system update can be divided into full-volume update and incremental update, and in general, the embedded device adopts a full-volume update mode, and the system update data needs to include complete system data. In this case, the formatting operation may be performed simultaneously in the process of dividing the system partition.
As technology advances, partitioning system partitions may not have been formatted. Therefore, the embedded device can be updated in an incremental updating mode, when the incremental updating mode is adopted, the system updating data can only comprise part of system data, at the moment, the integrity of the original system data in the embedded device needs to be ensured, the original system partition is divided into two system partitions in a non-formatting mode, and one system partition keeps the identification and the data of the original system partition and is called a first system partition. The other system partition sets an identification that is distinct from the first system partition, referred to as the second system partition. The first system partition comprises original system data, the equipment upgrading logic installs a program of the system updating data into the first system partition, and upgrades the original system data, so that updated system data is obtained. And copying the updated system data in the first system partition to the second system partition, thereby completing the system update of the whole target system partition.
In the embodiment of the application, the single backup system of the embedded equipment is updated to the double backup system, and the situation that the embedded equipment cannot be started due to the aging of the memory chip of the embedded equipment can be reduced.
In a possible implementation manner, after updating the system data to be updated in the first system partition according to the system update data to obtain updated system data, referring to fig. 3, the method further includes:
and S153, adding a mark file in the first system partition.
The markup file is used to indicate that the system data in the system partition is complete. In the process of starting the embedded equipment of the dual-backup system, firstly, whether the system partitions have the marked files or not is detected, and the system data in the system partitions with the marked files are preferentially selected for starting.
Before copying the updated system data in the first system partition to the second system partition, the method further includes:
S16, restarting the embedded device according to the system data in the first system partition where the mark file is located.
And restarting the embedded device after the system data in the first system partition is updated and the mark file is added in the first system partition. The embedded device selects system data in a system partition (a first system partition) with the marked file for starting, and copies the system data in the first system partition into a second system partition.
After the embedded device completes the update of the first system partition, the update of the second system partition is not directly started because the embedded device is still using system data corresponding to the single system partition. Adding a mark file in a first system partition, and restarting the embedded device; during the restarting process, the embedded device will check the mark files in the first system partition and the second system partition, and because the mark files exist in the first system partition, the embedded device is started according to the system data in the first system partition. After the restart of the embedded device is completed, the system data corresponding to the dual-system partition in actual use can be copied into the second system partition by the system data in the first system partition, so that the update of the second system partition is completed.
In the embodiment of the application, the mark file is utilized to distinguish the first system partition which is updated completely from the second system partition which is not updated, thereby reducing the condition of starting error,
In one possible implementation manner, the system partition mode represented by the partition table file is a single system partition, and the current actual system partition mode is a dual system partition;
Referring to fig. 4, if the system partition is different, the system partition is repartitioned according to the system partition mode indicated by the partition table file, to obtain a target system partition, which includes:
And S142, if the two system partitions are different, the original double system partitions are re-divided into target system partitions according to the single system partitions represented by the partition table files, wherein the target system partitions are single system partitions.
When the partition table file represents a single system partition, and the current actual system partition of the embedded device is a dual system partition, two system partitions of the embedded device need to be combined into one system partition to obtain a target system partition. The device upgrade logic installs the program of system update data into the target system partition.
In the embodiment of the application, the update of the embedded equipment from the double-backup system to the single-backup system is realized, and the condition of update failure of the embedded equipment system caused by insufficient memory chip space of the embedded equipment can be reduced.
In one possible manner, the original dual-system partition includes a third system partition and a fourth system partition, and the identifier of the target system partition is the same as the identifier of the third system partition; referring to fig. 5, the method further includes:
S17, after the error reporting information aiming at the fourth system partition is acquired, discarding the error reporting information.
Although the updating of the third system partition is completed, the system actually used by the embedded device is a dual-backup system, so that after the updating of the third system partition is completed, the updating of the system data is automatically performed on the fourth system partition and a mark file is added in the fourth system partition, but the fourth system partition does not exist at this time, an error reporting message is generated, and after the error reporting message for the fourth system partition is acquired, the error reporting message is directly discarded, so that the situation that the system repeatedly tries to update the fourth system partition according to the error reporting message is prevented.
In the embodiment of the present application, the third system partition and the fourth system partition do not mean that there are three system partitions or four system partitions in the embedded device, and the third and fourth partitions are only used to distinguish one system partition from another system partition, which is independent of the number. Under the condition that the identification of the target system partition is the same as the identification of the third system partition, according to the update logic of the dual-backup system, a fourth system partition is required to be updated and a mark file is added, and the adding object of the mark file is set as the fourth system partition, an error report message aiming at the fourth system partition system is received, wherein the error report message comprises an error report message of the update failure of the fourth system partition system and an error report message of the addition failure of the mark file of the fourth system partition system. The embedded device directly discards the error message without performing other processing on the error message.
In the implementation of the application, under the condition that the identification of the target system partition is the same as the identification of the third system partition, the adding object of the mark file is set as the fourth system partition, and the error message aiming at the fourth system partition system is discarded, so that the system resource waste caused by analyzing and processing the error message aiming at the fourth system partition system can be reduced, and the processing of unnecessary error message can be reduced.
In one possible implementation manner, before the acquiring the system update package, the method further includes: and sending the attribute parameters of the system partition, wherein the attribute parameters of the system partition comprise the total capacity of the system partition and the health parameters of a memory chip for storing the system data.
The embedded device may send a system partition attribute parameter to the update server, where the system partition attribute parameter includes a total capacity of a system partition of the embedded device and a health parameter of a memory chip storing system data. The health parameter of the memory chip is used to indicate the performance of the memory chip, and may be, for example, a factory time of the memory chip, a cumulative number of IO (input/output) errors, a cumulative number of erasures, or the like. In addition, the system partition attribute parameters may also include parameters such as the number of system partitions, the identification of the system partitions, and the like.
After receiving the system partition attribute parameters of the embedded device, the update server determines the partition table file of the embedded device according to the system partition attribute parameters. When a system update package is sent to the embedded device, the partition table file of the embedded device is added to the system update package.
The update server may obtain the total data amount of the updated system, for example, in the case that the total capacity of the system partition in the attribute parameters of the system partition is not less than twice the total data amount, and the health parameter of the memory chip indicates that the memory chip is at risk, it is determined that the partition table file indicates a dual-system partition. For example, in the case where the total capacity of the system partition is less than twice the total data amount in the system partition attribute parameter, it is determined that the partition table file represents a dual system partition. For example, in the case where the total capacity of the system partition is not less than twice the total data amount in the system partition attribute parameter, and the health parameter of the memory chip indicates that the memory chip is not at risk, it is determined that the partition table file indicates a dual-system partition.
Under the condition that the health parameter of the memory chip is smaller than a preset threshold, for example, the accumulated IO (the number of errors is smaller than the preset threshold), the health parameter of the memory chip is determined to indicate that the memory chip is not at risk, otherwise, the health parameter of the memory chip is determined to indicate that the memory chip is at risk.
In the embodiment of the application, the system partition attribute parameters are sent, so that the corresponding partition table file can be conveniently determined.
The following description will specifically refer to an embedded device as an NVR (Network Video Recorder, network hard disk recorder).
The user can remotely complete the process of starting the device after upgrading the embedded device system in a browser mode and the like. The process comprises the following steps:
Step one: and acquiring a system update package uploaded by a user, and upgrading the NVR system through a browser.
Step two: after the NVR receives the system update package, the system update package is analyzed and checked, and the like.
Step three: and the NVR judges according to the partition table file in the system update package, and if the system partition is changed, the NVR single-double backup partition is adjusted.
Step four: and the NVR writes the program in the system update package into the partition according to the actual single-double backup partition.
Step five: and starting a program from the system partition by the NVR according to the actual single-double backup partition, and maintaining the system partition data.
After the upgrade package is analyzed, the NVR issues the partition table file in the upgrade package to uboot, the uboot compares the partition table file with the system partition information in the NVR, and if the difference exists, the corresponding system partition is adjusted, for example, the original dav0 partition is divided into dav0 partition and dav1 partition again; or the dav0 and dav1 partitions are merged and divided into dav0 partitions. The process comprises the following steps:
Step one: when NVR is upgraded, a system update package is analyzed, a partition table file is taken out, and the partition table file is issued to uboot
Step two: after uboot receives the partition table file issued by NVR, analyzing and checking the partition table file to ensure the validity of the data
Step three: uboot compares the partition table file with the actual system partition.
Step four: if the difference exists, the corresponding system partition is adjusted, otherwise, the system partition is not adjusted.
When the NVR is a single backup system, the running program and the executed logic are single backups. If the system is required to be adjusted to double-backup, a partition table file representing a double-system partition is required to be placed in a system update package, the system partition is adjusted by uboot, then an upgrading program stores the program in the system update into dav0 (because the existing program is subjected to single-backup logic), meanwhile, a mark file is added into dav0, after NVR upgrading is successfully restarted, new double-backup logic is executed, data is copied from dav0 to dav1, and the equipment is switched from single-backup to double-backup.
The specific process of switching the single backup system to the double backup system comprises the following steps:
Step one: NVR running program is single backup, and upgrade logic is single backup
Step two: and upgrading NVR by using a system update package comprising partition table files of the double system partitions through a browser, and dividing dav0 and dav1 partitions according to the partition table files by uboot.
Step three: the upgrade logic stores the system update package program in dav0 and adds a markup file at dav 0.
Step four: and (5) finishing upgrading, and restarting the equipment.
Step five: and running a new program, starting data from dav0 according to the marked file in dav0, copying the data in dav0 to dav1, and setting the marked file in dav1 according to the judgment that the dual-backup mechanism is started.
Step six: the NVR operates normally in a dual backup form, and is restarted again by the user.
Step seven: normal existing dual backup execution logic, i.e., determines which is the normal partition based on the tag files in dav0, dav1, i.e., starts from that partition.
The specific process of switching the single backup system by the double backup system comprises the following steps:
Step one: the NVR has run the program as dual backup and the upgrade logic is also dual backup.
Step two: using a system update package including a partition table file of a single system partition, uboot is repartitioned into dav0 partitions according to the partition table merging dav0 and dav1 by a browser upgrade apparatus.
Step three: the upgrade logic stores the system update package program into dav1, and adds a mark file into dav1, at this time, because dav1 partition does not exist, writing fails, and the partition is adjusted to be a single partition in the upgrade process, so that errors are not reported, and the execution is continued.
Step four: the upgrade logic stores the upgrade package program in dav 0.
Step five: and (5) finishing upgrading, and restarting the equipment.
Step six: and the new program is operated, and the single backup mechanism is started from dav0 according to the judgment, so that the system is operated.
