For example, the upgrade, addition and deletion of algorithms in intelligent devices.

[0003] In the prior art, the upgrade of algorithm files generally involves first decompressing the algorithm files into the free memory of the storage device, and then overwriting the algorithm files in the memory onto the storage medium. However, with the iterative update of the intelligent algorithm, the algorithm files are also getting larger, and the memory space of the embedded storage device is relatively limited. When using the storage device to upgrade large files, in order to ensure the normal decompression of the compressed package of the upgrade file, the device needs to turn off all functions to provide sufficient memory for the upgrade. Since all functions are turned off, the device cannot record and store during the upgrade, and sometimes the device needs to be restarted, which results in the loss of video during the upgrade, and it is even more impossible to perform operations such as video analysis.

[0029] In this embodiment, an algorithm upgrade method is provided. Figure 2 : is a flow chart of the algorithm file upgrade method in an embodiment of the present method. Figure 2 As shown, the process includes the following steps:

[0030] Step S201, obtaining an algorithm file upgrade instruction.

[0031] The purpose of this embodiment is to upgrade the algorithm file, that is, to upgrade the original algorithm file in the monitoring device to an upgraded algorithm file. It can be understood that in this step, the purpose is to enable the device to start upgrading the algorithm file. Therefore, before upgrading the algorithm file, it is first necessary to obtain an algorithm file upgrade instruction to enable the device to upgrade the algorithm file.

[0032] Step S202: Perform upgrade preprocessing on the monitoring device based on the upgrade instruction of the algorithm file. The upgrade preprocessing includes shutting down non-core processes of the monitoring device. The core processes include the recording process.

[0033] In this embodiment, after receiving the algorithm file upgrade instruction, the algorithm file upgrade of the monitoring device begins. It is understandable that before the algorithm file upgrade, in order to ensure the smooth progress of the upgrade, upgrade preprocessing is required to ensure the successful upgrade of the algorithm file. It is understandable that the upgrade preprocessing may include shutting down non-core processes of the monitoring device. In this embodiment, all processes running in the monitoring device except the recording process are shut down, and only the recording process is turned on. The purpose of the upgrade preprocessing is to ensure that there is enough memory in the monitoring device to prepare for the decompression and installation of the algorithm file.

[0034] Step S203: acquiring the segmented compressed upgrade algorithm file based on the algorithm file upgrade instruction, and decompressing the upgrade algorithm file segment by segment and installing it to the monitoring device.

[0035] After the upgrade preprocessing step is completed in this embodiment, it is necessary to start upgrading the algorithm file. In this embodiment, the monitoring device first needs to obtain the upgrade algorithm file based on the algorithm upgrade instruction. It can be understood that the upgrade algorithm file should be compressed in segments. Only the upgraded algorithm file compressed in segments can be decompressed in segments later. In addition, the upgrade algorithm file can be obtained from the cloud network or from an external hard disk. This embodiment does not make specific restrictions. It only needs to ensure that the monitoring device can obtain the upgraded algorithm file that is required by the current monitoring device and is compressed in segments. Then, the upgraded algorithm file is decompressed and installed on the monitoring device by segmented decompression. In this embodiment, since the upgraded algorithm file obtained is compressed in segments, Therefore, when decompressing the upgrade algorithm file, the upgrade algorithm file can be decompressed by segmented decompression, that is, each part of the file in the overall file is decompressed in turn. It can be understood that when decompressing the file by segmented decompression, only a part of the memory for decompressing all the files is needed to decompress it. Therefore, the occupied memory is a part of the memory occupied by the overall decompressed file in the prior art. Then, after a part of the file is decompressed and installed in the monitoring device, the next part is decompressed. Based on this, the overall upgrade algorithm file is divided into several part files and installed in the monitoring device in segments. The memory occupied when the algorithm file is installed can be less than the memory occupied by the current common method of decompressing the upgrade algorithm file as a whole, so as to decompress and install the algorithm file to complete the algorithm file upgrade.

[0036] Through the above steps, the algorithm file upgrade instruction is first obtained, and then based on the algorithm file upgrade instruction, the monitoring device is upgraded preprocessed, the upgrade preprocessing includes shutting down the non-core processes of the monitoring device, and the core processes include the recording process, and then based on the algorithm file upgrade instruction, the segmented compressed upgrade algorithm file is obtained, and the upgraded algorithm file is segmented and decompressed and installed on the monitoring device. The problem of the prior art that all functions need to be shut down when upgrading the algorithm file, resulting in missing recordings when upgrading the algorithm file, is solved, and the memory of the recording function can be guaranteed to be free when the algorithm file is upgraded, and the recording can still be performed when the algorithm file is upgraded, and the integrity of the recording during the algorithm file upgrade is guaranteed.

[0037] In another embodiment, before acquiring the segmented compressed upgrade algorithm file based on the algorithm file upgrade instruction, the method further includes: sending a file acquisition instruction based on the algorithm file upgrade instruction, so that the file sending end performs segmented compression on the upgrade algorithm file based on the file acquisition instruction.

[0038] In this embodiment, after completing the preprocessing stage, the segmented compressed upgrade algorithm file is obtained based on the algorithm file upgrade instruction. It can be understood that before obtaining the segmented compressed upgrade algorithm file, it is necessary to ensure that the upgrade algorithm file is segmented and compressed. Therefore, it is necessary to send a file acquisition instruction based on the algorithm file upgrade instruction. Then, the file sending end compresses the upgrade algorithm file in segments before sending the upgrade algorithm file to the monitoring device, so as to ensure that the upgrade algorithm file sent to the monitoring device is a segmented compressed upgrade algorithm file, and to ensure that the subsequent segmented decompression can be performed normally.

[0039] In one of the embodiments, before performing upgrade preprocessing on the monitoring device, it also includes: obtaining the file identifier of the upgrade algorithm file and the file identifier of the current algorithm file, the file identifier including the file update time and the file version number; comparing the file identifier of the upgrade algorithm file with the file identifier of the current algorithm file, and if the file representation of the upgrade algorithm file is different from the file identifier of the current algorithm file, then performing upgrade preprocessing.

[0040] It can be understood that in this embodiment, before the upgrade preprocessing of the device, it also includes confirming whether an upgrade is required. First, the file identifiers of the upgrade algorithm file and the current algorithm file are obtained, and then the file identifier of the upgrade algorithm file is compared with the file identifier of the current algorithm file. Then, whether to upgrade can be confirmed based on the comparison result. It can be understood that based on the file upgrade time and the file version number, it can be determined whether the file version of the current algorithm file is ahead of the file version of the current upgrade algorithm file, or it can be verified whether the upgrade algorithm file is the same as the current algorithm file. It is easy to understand that only when the version of the upgrade algorithm file is ahead of the current algorithm file, or the upgrade algorithm file is different from the current algorithm file, can it be determined whether the current monitoring device continues to perform upgrade preprocessing and subsequent algorithm file upgrades. Based on this, it can be avoided to upgrade old version files or the same version files to ensure the effectiveness of the upgrade. That is, the upgrade can be performed based on whether the update time of the algorithm file is the latest, and it can also be determined based on whether the file identifier of the upgrade algorithm file is consistent with the file identifier of the current version of the algorithm file. There is no limitation in this embodiment. It only needs to ensure that before performing the upgrade preprocessing, it is confirmed whether the upgrade preprocessing is required based on the file identifiers of the algorithm files at both ends.

[0041] In some embodiments, before decompressing the upgrade algorithm file to the monitoring device, it also includes: obtaining the memory required for segmented decompression of the algorithm file and the available memory of the monitoring device, comparing the required memory and the available memory, obtaining the memory comparison result, and determining whether to decompress the upgrade algorithm file to the monitoring device based on the memory comparison result.

[0042] In this embodiment, before starting to decompress the upgraded algorithm file to the monitoring device, it is necessary to obtain the memory required for segmented decompression of the algorithm file and the current available memory of the monitoring device. Then, based on the comparison result of the required memory and the available memory, it can be judged whether the available memory in the current monitoring device is sufficient to meet the memory required for segmented decompression of the upgraded algorithm file in the device. It can be understood that the memory required for segmented decompression of the algorithm file includes the memory occupied by the algorithm file itself, the memory occupied by decompression, etc. When the required memory is less than the current available memory, it can be judged that the current monitoring device can perform normal decompression and installation of the algorithm file. It is easy to understand that when the memory required for segmented decompression of the current algorithm file is greater than the available memory, it is judged that the current monitoring device cannot perform normal decompression and installation of the algorithm file, and the installation is suspended until the available memory is sufficient to perform normal decompression and installation. Based on this, it can avoid the occurrence of insufficient memory during installation.

[0043] In another embodiment, the algorithm file upgrade method further includes: marking the video files generated based on the video process when the non-core process is closed, intercepting the marked video files and saving them separately to obtain the upgraded video files.

[0044] It is understandable that when the device is performing upgrade preprocessing, in order to ensure that there is enough memory to upgrade the algorithm file, all processes except the video recording function are closed. It is understandable that there is no process and free memory at this time to parse and process the video files during the upgrade of the algorithm file. Based on this, in this embodiment, when the non-core process is closed, that is, from the start of the upgrade preprocessing to the completion of the upgrade, the video files during this period are marked and saved separately for distinction, so that they can be easily distinguished and extracted after the upgrade is completed, so as to parse and process them. You can wait for the device to be upgraded and the memory of the device is free to perform subsequent analysis, or upload it to the network for cloud analysis. It only needs to ensure that the video files during the upgrade can be analyzed. By marking and saving the video files generated by the video recording function retained during the upgrade, it can be ensured that the video files that have not been processed and analyzed during the upgrade are distinguished in time, which is conducive to subsequent processing and improves the degree of file distinction.

[0045] In some embodiments, after decompressing the upgrade algorithm file in segments and installing it on the monitoring device, the method further includes: obtaining the installation result, which includes installation success and installation failure; when the installation result is installation success, enabling the monitoring device to apply the upgrade algorithm file and start the non-core process in the monitoring device; and parsing the video file during the upgrade. When the installation result is installation failure, generating an installation failure report and / or alarm.

[0046] In this embodiment, after the upgrade algorithm file is decompressed in segments and installed on the monitoring device, it is necessary to obtain the installation result. The way to obtain the installation result can be to test whether it can be successfully enabled by enabling the algorithm file, or to perform algorithm file verification. This is not specifically limited in this embodiment. It is only necessary to ensure that the installation result of the algorithm file can be obtained. The installation result obtained should include successful installation and failed installation. When the installation result is successful installation, it proves that the upgrade algorithm file has been successfully deployed to the monitoring device. At this time, you can exit the upgrade mode, that is, reopen the process closed during the upgrade preprocessing, and apply the upgrade algorithm that has been installed in the device at this time. file, switch the algorithm dynamic library and model files of the algorithm analysis to the upgraded versions, so that it can run the device normally based on the upgraded algorithm file, and parse the previously marked upgrade video files when there is free time in the device memory, to ensure that the device enters normal working state in time after the upgrade; when the installation result is an installation failure, it is understandable that an installation failure report needs to be generated to the device side or the technician, and / or an alarm is generated to prompt the technician that the installation failed. Optionally, the algorithm file can be upgraded again or the upgrade mode can be exited, that is, the upgrade algorithm file is deleted and the device process is restarted, which can ensure the normal operation of the device and improve the upgrade efficiency.

[0047] In another embodiment, parsing the video file during the upgrade includes: obtaining the available computing power of the current monitoring device and the computing power required to parse the video file during the upgrade; comparing the available computing power with the required computing power and obtaining the computing power comparison result, and based on the computing power comparison result, the monitoring device parses the video file during the upgrade while operating normally.

[0048] In this embodiment, after the device is installed and operates normally, it is also necessary to parse the upgrade video files that were previously marked during the upgrade. However, when parsing the upgrade video files, it is first necessary to obtain the computing power available for the current monitoring device. The available computing power of the device is the processing power that the device can provide for parsing the video, that is, the computing power that can be used to parse other files while ensuring the normal operation of the device, as well as the computing power required for parsing the upgrade video. By comparing the available computing power with the required computing power, it can be determined whether the current device has spare power to parse the upgrade video files. When it is determined that there is currently sufficient spare computing power, the upgrade video files are parsed based on the normal operating process. It can be understood that if there is currently insufficient spare computing power, the available computing power is continuously obtained, and the video files are parsed when there is sufficient spare computing power in the monitoring device, thereby ensuring the utilization effect of the device computing power and improving the utilization rate of the device computing power.

[0049] This embodiment also provides an algorithm file upgrade method. Figure 3 FIG. 1 is a flow chart of an algorithm file upgrade method in one embodiment of the present method. Figure 3 As shown, the process includes the following steps:

[0050] When performing upgrade preprocessing, first check whether the buffer can write data, that is, check whether the current available memory in the buffer is larger than the memory occupied by the upgrade algorithm file. If the buffer cannot write data at this time, repeat the check of available memory, and wait for the buffer to write data before proceeding to the next step. It is understandable that when the device is running based on the core functions, the occupied memory is different in different stages; when it is detected that the buffer can write data, the compressed data of the upgrade algorithm file is written to the buffer. It is understandable that writing the compressed data of the upgrade algorithm file to the buffer is to move the compressed package of the algorithm upgrade file to the memory, and then check whether the content in the buffer can be decompressed, that is, whether the current available memory size of the buffer can decompress the upgrade algorithm file. It is understandable that if the available memory is larger than the size required to decompress the upgrade algorithm file, If the available memory is smaller than the memory required for decompressing the upgrade algorithm file, the available memory is repeatedly detected until it is detected that the available memory in the buffer is larger than the memory required for decompressing the upgrade algorithm file, and then the decompression is started. It is easy to understand that when the upgrade algorithm file is about to be decompressed, the buffer needs to be blocked to prevent memory changes or file damage; then the upgrade algorithm file in the buffer is read, that is, the upgrade algorithm file in the buffer is decompressed to the monitoring device. When the upgrade algorithm file is decompressed to the monitoring device, the upgrade is deemed to be completed; it can be understood that in other embodiments, it is also possible to detect whether the buffer can be written and decompressed data. When it is determined that the data can be written and decompressed, the buffer is blocked, and the writing and decompression part is started. It is only necessary to ensure that the upgrade algorithm file can be successfully installed on the monitoring device.

[0051] Figure 4 FIG. 1 is a flow chart of an algorithm file upgrade method in another embodiment of the present method. Figure 4 As shown, in the present embodiment, after the algorithm file is upgraded, a step is required to parse the video file during the upgrade. It can be understood that in the present embodiment, it is first necessary to determine whether the device has any remaining intelligent computing power, that is, the computing power that can parse the video file. If the current device has any remaining intelligent computing power, the video file during the upgrade can be parsed. It can be understood that the parsing of the video file during the upgrade is performed without affecting the normal operation of the device. If there is no remaining intelligent computing power, the device continues to parse the real-time video file, that is, works normally, and waits for the device to have any remaining intelligent computing power before parsing the video file during the upgrade.

[0052] It should be noted that the steps shown in the above process or the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
