The upgrading process of the utility model is shown in figure 2,

1. the development platform of the line controller 100 modularizes and documents the firmware program package;

2. the firmware program package is divided into a page list, a function list, a logic association list and a picture text list;

3. the line controller 100 is connected to the cloud server 200, and the cloud server 200 generates an upgrade file according to the upgrade request;

4. the line controller 100 receives the upgrade file, completes the upgrade, and deletes the redundant file.

The process of a director upgrade is described below by a complete example process:

1. the current firmware program version of the line controller 100 is V1.0; the firmware packages include module versions of a page list (V1.0), a function list (V10), a logic association list (V1.0), and a picture text list (V10), and the corresponding picture text resource file package (corresponding to the picture text list) is also marked as V1.0.

2. The firmware program version to be upgraded by the line controller 100 is V2.0; because it is an iterative upgrade development based on firmware program version V1.0, its software modules are not completely changed; only part of the modules are modified; if the page list is not changed or V1.0; the function list changes to V2.0 when new function addition occurs; the logical association list also changes to V2.0; the picture text list also becomes V2.0 because the pixel references (file a, file B, file C) versions of the three picture files are added; the corresponding picture text file packet is added with a file A, B, C on the basis of the original file.

3. The firmware packages V1.0 and V2.0 of the line controller 100 are both stored in the cloud server 200, and when the line controller 100 is connected to the cloud server 200 through the wireless communication module 300, the current firmware package version V1.0 and the pre-upgraded firmware package version V2.0 are transmitted to the cloud server 200. After receiving the upgrade request of the line controller 100, the cloud server 200 automatically compares the firmware program packages V1.0 and V2.0 to generate a difference upgrade package. The difference upgrading package comprises a function list V2.0, a logic association list V2.0, a picture text list V2.0 and a picture file A, B, C; and two difference list files are generated by comparing the differences of the firmware package V2.0 and the firmware package V1.0: the first deleted file list and the second to-be-deleted file list; the statistics in the first deleted file list are files which exist in the firmware program package V2.0 but do not exist in the firmware program package V1.0, namely a file list which can be removed after the V2.0 is successfully upgraded; the statistics in the second file list to be deleted are files that exist in the firmware package V1.0 but do not exist in the firmware package V2.0, that is, a file list that can be deleted after the V2.0 fails to be upgraded. The difference upgrade package is formed by the above 8 independent files.

4. The line controller 100 starts a differential upgrade package reception and receives the upgrade program package onto the line controller storage module 120; then the control module 110 starts verification, if the verification is successful, the control module 110 reads the file names in the first file list to be deleted and deletes the file names one by one, and restarts the program; if the verification fails, the control module 110 reads the file names in the second to-be-deleted file list, and then deletes the file names one by one, and restarts the program. Most of the programs are resource files such as pictures and texts, which occupy a large storage space, and most of the programs do not need to modify icons and the like for modifying functional logic; therefore, the file size of the upgrade package can be greatly reduced by upgrading the scheme, the transmission data volume is reduced, and the upgrade success probability is improved.

The process of the cloud server 200 when processing the upgrade request of the line controller 100 is as follows:

firstly, the cloud server 200 receives version information of a firmware program package of the line controller 100, wherein the current firmware program package version is V1.0, and the pre-upgraded firmware program package version is V2.0;

secondly, the cloud server 200 starts to compare the stored firmware program packages V1.0 and V2.0, and respectively performs version comparison on the page list, the function list, the logic association list, the picture text list and the picture text file package; summarizing and packaging files with version upgrading into a difference upgrading package;

thirdly, the cloud server 200 generates a first file list to be deleted according to files which are present in the firmware package V2.0 and are not present in the firmware package V1.0, that is, a file list which can be deleted after V2.0 is successfully upgraded; generating a second file list to be deleted according to files which exist in the firmware program package V1.0 but do not exist in the firmware program package V2.0, namely a file list which can be deleted after the upgrade of the firmware program package V2.0 fails; generating the two lists of files to be deleted;

fourthly, the cloud server 200 transmits the difference upgrade package and the list of files to be deleted to the line controller 100.

In some embodiments of the present invention, the cloud server 200 may automatically compare the latest version with the historical version when a new program version is uploaded during development, and generate a difference upgrade package and a file list to be deleted in advance.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
