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

[0084] 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 invention relates to a system updating and upgrading method in an enclosed environment. The method comprises the following steps that (1) a software maintenance worker encodes an upgrading file into a binary data stream through a precoding protocol algorithm, and generates a colorful two-dimension code through a colorful two-dimension code encoding tool; (2) the generated colorful two-dimension code is arranged on a carrier and displayed in front of a camera of a device to be upgraded; (3) a preset updating and upgrading service in the device to be upgraded reads the colorful two-dimension code, analyzes the colorful two-dimension code through a colorful two-dimension code decoding module and then analyzes and restores the analyzed binary data stream through the precoding protocol to obtain the original upgrading file; (4) the updating and upgrading service uses the restored upgrading file to update and upgrade an application program or a software system. According to the method, in the upgrading and updating process, colorful two-dimension code media do not need to make contact with the device to be upgraded, the upgrading process is intelligent and reliable, data encryption is supported, and updating and upgrading of the system in an enclosed environment are achieved.

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 ...
