Remote software upgrading technique

Abstract

The invention discloses a remote embedded software upgrading technique by using an embedded boot sector Bootloader software upgrading technique to be combined with a communication protocol carrier. The remote embedded software upgrading technique comprises three stages: startup, operation and detection in a first stage, upgrading program transmission in a second stage, and execution of an application program in a third stage. The boot sector Bootloader technique is combined with other communication protocols, such as a general packet radio service (GPRS), a transmission control protocol (TCP)/internet protocol (IP), PROFIBAS and other protocols so as to realize remote software transportation. A boot sector Bootloader firmware protocol of an information system is integrated to reasonably and stably realize software transportation and one-to-many or fixed-point upgrading, and solve the compatibility problem of software upgrading with standard protocol interfaces. Meanwhile, the self-verification and retransmission function of a standard communication protocol is utilized to ensure the reliability of the software upgrading and improve the upgrading success rate and the antijamming capability in severe environments.

AI Technical Summary

Benefits of technology

This patented technique uses secure communications between two computers called servers for transferring programs over long distances without interfering with each others' signals. It achieves this by breaking down an update file into smaller pieces before sending them individually instead of all together. Additionally, there are also techniques like streaming updates through different types of networks such as LANs (Local Area Network) or wireless connections. Overall, these improvements make updating applications faster than traditional methods but still maintain their effectiveness even when connected across longer distance paths due to stronger antijamming capabilities provided during normal operation.

Problems solved by technology

This patents discusses various issues related to upgraded software applications that can cause instabilities during transferring between devices due to differences in their physical properties (such as signal speed) even if they were initially installed correctly by an IT staff member working for technical problem addressed earlier). Additionally, there may still remain challenges when migrating from one device into another without affecting its performance capabilities.
