Problems solved by technology

The user updates these patches, that is, the upgrade is completed. The software upgrade is to better meet the user's needs and prevent virus intrusion; interface or use solid-state electronic devices such as U disks and SD cards, but for some special environments, such as closed environments, where the above-mentioned conditions do not exist, the system is difficult to upgrade. The personnel have also made many attempts, but the technical problem has not been solved well. There are certain limitations in the system upgrade in the prior art, and it is difficult to realize the system upgrade without the network or other electronic devices. Therefore, it is urgent The need for a new technical solution to solve the above technical problems

Embodiment 1

[0048] see figure 1 , a system update and upgrade method in a closed environment, the technical solution converts the upgrade file into a color two-dimensional code through the upgrade file to color two-dimensional code system, uses the camera in the device to be upgraded to scan the color two-dimensional code, through the upgrade update The service system restores it to an upgrade file, and completes the final upgrade update.

[0049] see figure 2 , figure 2 It is a flow chart of the overall upgrading method; a system updating and upgrading method in a closed environment, the method includes the following steps,

[0050] 1) Software developers or maintenance personnel compile the upgrade file into a binary data stream using a pre-coding protocol algorithm, and generate a color QR code through a color QR code coding tool;

[0051] 2) Place the generated color QR code on the QR code carrier, and present it in front of the camera of the device to be upgraded; the color QR ...

Embodiment 2

[0083] see Figure 7 , Figure 8, a system update and upgrade system in a closed environment, the system includes an upgrade file transfer color two-dimensional code system and an upgrade update service system, the upgrade file transfer color two-dimensional code system includes a GZip compression module, an MD5 verification module, encryption Decryption module, data processing and precoding module, color two-dimensional code coding module and file processing module, the upgrade update service system includes GZip decompression module, MD5 verification module, encryption and decryption module, data processing and precoding module, color two-dimensional Dimensional code decoding module, file processing module and update service module; Described GZip compression module and GZip decompression module carry out compression and decompression to data block respectively by GZip algorithm; Described MD5 verification module calculates data block by MD5 algorithm, generates MD5 check c...

Abstract

The present invention relates to a method for updating and upgrading a system in a closed environment. The method includes the following steps: 1) The software maintainer encodes the upgrade file into a binary data stream using a pre-coding protocol algorithm, and generates a color binary data stream through a color two-dimensional code coding tool. QR code; 2) Place the generated color QR code on the carrier and present it in front of the camera of the device to be upgraded; 3) The update and upgrade service preset in the device to be upgraded reads the color QR code and passes the color QR code The code decoding module parses, and then parses the parsed binary data through the pre-encoding protocol to restore the original upgrade file; 4) The update upgrade service uses the restored upgrade file to update the application program or software system. During the upgrade and update process of the method, the color two-dimensional code medium does not need to be in contact with the device to be upgraded, the upgrade process is intelligent and reliable, supports data encryption, and realizes system update and upgrade in a closed environment.

Description

technical field [0001] The invention relates to an upgrading method, in particular to a system updating and upgrading method in a closed environment, and belongs to the technical field of computer Internet. Background technique [0002] Software upgrade refers to the way that when the software developer writes the software, because the designer does not consider comprehensively or the program function is not perfect, after the software is released, the program is modified or new functions are added, and the method is released in the form of a patch. . The user updates these patches, that is, the upgrade is completed. The software upgrade is to better meet the user's needs and prevent virus intrusion; interface or use solid-state electronic devices such as U disks and SD cards, but for some special environments, such as closed environments, where the above-mentioned conditions do not exist, the system is difficult to upgrade. The personnel have also made many attempts, but ...
