Background
Internet cameras are a new generation of products that combine traditional cameras with web-based video technology. The video signal transmitted by the camera is compressed by the high-efficiency compression chip after being digitized, and is transmitted to the internet server through the network bus. Users on the network can directly use the browser to watch the camera image on the Internet server, and authorized users can also control the action of a camera holder lens or operate system configuration.
Generally, in order to ensure the upgrade security of the internet video camera, a backup of the door data file is required before the upgrade. Currently, there are two main backup approaches. One way of backup is to backup all partitions including application partitions, configuration partitions, kernel partitions, root file system partitions, etc. If all partitions are backed up, a large number of memory chips are required to implement the backup, resulting in an increase in hardware cost. And the other backup mode can save the hardware cost, namely only backing up the application partition, the configuration partition and the like before upgrading, but not backing up the kernel partition and the root file system partition.

Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
The technical solution of the present invention will be described below by way of specific examples.
Referring to fig. 1, a schematic flow chart illustrating steps of a system upgrading method for an internet camera according to an embodiment of the present invention is shown, which may specifically include the following steps:
s101, starting a main partition system of the Internet camera;
for ease of understanding, a brief description of the partitioning of the internet camera is provided below.
Generally, a partition can be regarded as a memory chip (flash), and an internet camera generally includes the following partitions:
kernel partition: the kernel partition is the most core part of the Linux operating system and is used for managing peripheral devices, processors, memories, hard disks and the like in the embedded system. The operating system located in the Kernel partition may be referred to as a main partition system.
Partitioning the Rootfs: i.e., the root file system partition, is a directory structure containing directory structures and files necessary for the start-up of the Linux operating system.
Boot partitioning: namely, the starting partition, is used for guiding the normal starting of the Kernel partition after the equipment is powered on.
Specifically, after the device is powered on, the Boot program is executed first, the Kernel is started by the Boot, after the Kernel loads the relevant driver, the Rootfs partition is mounted, and a default program in the Rootfs partition, which is generally an init program, is executed. Then, the init program returns to start other Linux kernel programs and the user's own programs. Some types of boots also have network access, flash, and erase capabilities.
The memory chip may further include an application partition, a configuration partition, and the like according to the difference between the data storage and the file configuration. The application partition and configuration partition may be partitions of user programs and files or data related to program configuration.
Upgrading partitions means that the corresponding flash blocks are erased and then written into a new program. If an exception occurs during an erase or write operation, the device will be rendered unusable. The upgrading process of the user partition, the configuration partition and other partitions is the same as that of the other two partitions (the Kernel partition and the Rootfs partition), except that the equipment can still be started after the upgrading of the other partitions fails, and once the Kernel partition and the Rootfs partition are damaged, the equipment cannot be started or restarted repeatedly.
S102, detecting whether a main partition upgrading packet aiming at the main partition system exists or not;
in the embodiment of the present invention, when an operating system (i.e., a main partition system) in a Kernel partition is upgraded, after the main partition system is started, whether a main partition upgrade package for the main partition system exists may be detected.
In a specific implementation, after the main partition system is started, the internet server in communication connection with the internet camera may send an upgrade instruction to the internet camera to notify the main partition system of upgrading. Therefore, whether the main partition system needs to be upgraded can be determined by detecting whether an upgrade instruction sent by the internet server is received.
Of course, if there is a problem with the primary partition system, for example, it is detected that the primary partition system fails to be upgraded at the previous time, it may be considered that the primary partition system needs to be upgraded again to restore the normal function of the primary partition system. In this case, it can also be considered that there is a main partition upgrade package for the main partition system.
If the main partition upgrading package for the main partition system exists, step S102 may be executed to start a repair partition system of the internet video camera, and upgrade or repair the main partition system is implemented by the repair partition system.
S103, starting a repair partition system of the Internet camera;
in embodiments of the present invention, the repair partition system may be a stand-alone partition system, not a backup of the primary partition system. The repair partition system comprises a simplified kernel (only comprising network related functions, read-write flash related functions and the like), and the repair partition system mainly has the functions of downloading a main partition system upgrade package from an internet server and upgrading the main partition system.
Since only the repair functionality of the main partition system is included, and no other business logic is included, the repair partition can be trimmed to a minimum, e.g., the total size of the Boot partition, the main partition, and the repair partition can be only 8MB (Megabyte).
S104, guiding the repair partition system to download the main partition upgrade package;
after the repair partition system is started, a Boot program in the Boot partition may Boot the repair partition system to download a main partition upgrade package from the internet server, and then step S104 is executed to complete the upgrade of the main partition system.
And S105, upgrading the main partition system by adopting the main partition upgrading package.
In the embodiment of the invention, the main partition system of the Internet camera is started, whether the main partition upgrading package aiming at the main partition system exists is detected, if so, the repair partition system of the Internet camera can be started, and then the repair partition system is guided to download the main partition upgrading package, so that the main partition system is upgraded by adopting the main partition upgrading package. Aiming at the characteristic that an internet camera must access an internet server, the embodiment realizes the upgrading operation of the main partition system by configuring an independent repairing partition and the repairing partition system in the repairing partition, so that the device can be normally recovered after any partition is damaged in the upgrading process, and the device cannot occupy excessive storage to backup each partition, thereby ensuring the upgrading safety and saving the hardware cost of the device.
Referring to fig. 2, a schematic flow chart illustrating steps of another method for upgrading a system of an internet camera according to an embodiment of the present invention is shown, which may specifically include the following steps:
s201, starting a main partition system of the Internet camera, and detecting whether the main partition system fails to be upgraded;
it should be noted that the present embodiment describes the present solution from the perspective of the main partition system failing in the previous upgrade. In this case, the main partition system needs to be upgraded again through a certain processing means to recover the corresponding functions.
In the embodiment of the invention, when the main partition system of the internet camera is started, whether the main partition system fails to be upgraded at the previous time can be detected.
In the embodiment of the present invention, whether the primary partition system fails to be upgraded or not can be confirmed by flag bit information of the partition in which the primary partition system is located.
In a specific implementation, whether the upgrade fails may be determined by identifying preset identification bit information corresponding to the upgrade package of the main partition system, and then detecting whether the preset identification bit information is different from the current identification bit information of the main partition system.
For example, the last few bytes of a partition may be used as identification bits, such as the last two bytes. The flag bit may be cleared to 0x0000 at the beginning of the upgrade partition. After the upgrade of each upgrade package is completed, the identification bit of each upgrade package should be determined, and if the identification bit of each upgrade package can be 0xfefe, after the upgrade is completed, whether the partition is correctly upgraded can be judged by judging whether the last two bytes of the partition are 0 xfefe. If the last two bytes of the upgraded partition are indeed 0xfefe, the upgrade is successful, and if not, the upgrade is failed.
If the upgrade failure of the main partition system is detected, it can be confirmed that a main partition upgrade package for the main partition system exists, and the main partition system needs to be upgraded or repaired again.
S202, detecting whether an abnormality exists in a repair partition system of the Internet camera;
in the embodiment of the invention, the upgrading or repairing of the main partition system can be realized by repairing the partition system.
The repair partition system in this embodiment may be a stand-alone partition system and not a backup of the primary partition system. The repair partition system comprises a simplified kernel and mainly has the function of downloading a main partition system upgrade package from an internet server to upgrade the main partition system.
Since only the repair functionality of the main partition system is included, and no other business logic is included, the repair partition can be trimmed to a minimum, e.g., the total size of the Boot partition, the main partition, and the repair partition can be only 8MB (Megabyte).
Before the repair partition system is adopted to upgrade or repair the main partition system, whether the repair partition system has an exception or not can be confirmed firstly. If there is no exception in the repair partition system, step S203 may be executed to start the repair partition system through a series of operations; if the repair partition system is abnormal, step S207 may be executed to perform an upgrade operation on the repair partition system by downloading a repair partition upgrade package for the repair partition system.
S203, setting a preset environment variable as a first numerical value, and starting the repair partition system based on the environment variable of the first numerical value;
in the embodiment of the invention, the environment variable in the Boot partition can be set as the first value firstly, and then the recovery partition system is started.
Boot partition contains uboot environment variable, and the function of the Boot partition is responsible for starting a main partition system or repairing the partition system.
In the embodiment of the invention, the setting of the uboot environment variable can be realized by a standard function provided by Boot partition, and whether the main partition system is started or the repair partition system is started is determined by judging the specific value of the uboot environment variable.
Specifically, when the uboot environment variable is erramsk 1, the repairing partition system is started, and a flow for repairing or upgrading the main partition system is entered, and when erramsk 0, the main partition system is started. Therefore, the first value is errisk ═ 1.
S204, guiding the repair partition system to download the main partition upgrade package;
in the embodiment of the invention, the repair partition system can be guided to download the main partition upgrade package from the internet server through the bootstrap program in the Boot partition.
In a specific implementation, the storage location of the primary partition upgrade package in the internet server may be determined first, and then the primary partition upgrade package may be downloaded from the storage location through the repair partition system.
S205, erasing data in a storage chip corresponding to the main partition system;
s206, writing the main partition upgrading packet into a corresponding storage chip of the main partition system;
generally, upgrading a partition is to erase a corresponding flash block and then write a new program.
Therefore, before formal upgrade, data in a memory chip corresponding to the main partition system needs to be erased, and then the downloaded main partition upgrade package is written into the memory chip and refreshed, thereby completing the upgrade process of the main partition system.
S207, downloading a repair partition upgrading package aiming at the repair partition system, and adopting the repair partition upgrading package to upgrade the repair partition system.
In the embodiment of the present invention, when there is an abnormality in the repair partition system, the repair partition system may be first upgraded.
Specifically, a repair partition upgrade package for a repair partition system may be downloaded, and then the repair partition upgrade package is used to perform an upgrade operation on the repair partition system.
In some cases, it may cause the main partition system to not boot properly. Therefore, as an example of the present invention, when the main partition system of the internet camera is not normally started, it may be detected whether the main partition system is abnormal, and if the main partition system is abnormal, a repair partition system may be started, the repair partition system is guided to download the main partition upgrade package, and the main partition system is upgraded by using the main partition upgrade package; if the main partition system has no abnormality, the main partition system can be started again.
For the convenience of understanding, the system upgrading method of the internet camera according to the present invention will be described in several cases.
1. Primary partition system online upgrade
Fig. 3 is a schematic diagram illustrating an online upgrade process of a main partition system according to an embodiment of the present invention. According to the upgrade process shown in fig. 3, after the internet camera is powered on, the main partition system can be started normally. At this time, if an upgrade package for the main partition system exists in the internet server, the internet server sends an upgrade instruction to the internet camera, and the internet camera can start an online upgrade process.
During upgrading, the repair partition system may be first detected to determine whether the repair partition system is normal. If the system of the repair partition is normal, a standard function provided by the Boot partition can be called to set the uboot environment variable to be ERrmask 1, and the internet camera is restarted.
After the Boot partition is restarted, if the environment variable in the Boot partition is errask 1, the repair partition system can be started, the main partition upgrade package is downloaded through the repair partition system, and the main partition system is upgraded by refreshing the main partition flash.
After the upgrade is completed, the environment variable errask in the Boot partition can be cleared, the internet camera is restarted again, if the errask is judged to be 0, the main partition system is started, and the upgrade process is ended.
Of course, when the repair partition system abnormality is detected, the repair partition system online process may be executed.
2. Repairing partition system online upgrades
Fig. 4 is a schematic diagram illustrating an online upgrade process of a repair partition system according to an embodiment of the present invention. According to the upgrade process shown in fig. 4, after the main partition system is normally started, it is detected whether the repair partition system is abnormal, if so, the repair partition upgrade package may be downloaded, and the upgrade of the repair partition system is completed by updating the flash where the repair partition system is located.
3. Automatic repair main partition system
In the embodiment of the invention, automatic repair of the main partition system can be realized. For example, when the main partition system cannot be normally started, the automatic repair of the main partition system can be completed through the boot of the boot partition.
Fig. 5 is a flow chart illustrating an automatic repair of a main partition system according to an embodiment of the present invention. According to the flow shown in fig. 5, after the internet camera is powered on, if the main partition system cannot be normally started, the Boot program may be started, and whether the main partition system is abnormal is detected, if so, the repair partition system may be started by setting an environment variable in the Boot partition to errask 1, and then guiding the repair partition system to download the main partition upgrade package, and updating the flash of the main partition, thereby completing the repair of the main partition system.
After the repair is completed, the internet camera can be restarted.
4. Forced restart main partition system
In the embodiment of the invention, forced restart of the main partition system can be realized.
Fig. 6 is a flowchart illustrating a forced reboot of a main partition system according to an embodiment of the present invention. According to the flow shown in fig. 6, after the internet camera is powered on, if the environment variable is found to be that the error is 1, it may be detected whether the repair partition is normal. If the repair partition system is normal, the repair partition system can be started, and the main partition system is upgraded through the repair partition system. If the partition system exception is repaired, an attempt may be made to boot the main partition system. At this time, the environment variable may not be cleared and still become errask 1, and then the repair partition system online upgrade flow is executed.
It should be noted that, the sequence numbers of the steps in the foregoing embodiments do not mean the execution sequence, and the execution sequence of each process should be determined by the function and the internal logic of the process, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
