Abstract

The invention discloses a product online upgrading system and method based on multiple loading. The system comprises a configuration memory, a processing unit and a multi-loading unit, wherein a basic program and an application program are stored in the configuration memory in a partitioned manner; the processing unit receives an on-line upgrading data frame sent from the outside, and writes the on-line upgrading data frame into an application program partition in the configuration memory through a reloading unit; the multi-loading unit writes the online upgrade data frame into an application program partition and then skips to a first interrupt vector table in a newly written application program; when the upgrading fails, the multi-loading unit forcibly jumps from the first interrupt vector table to the second interrupt vector table of the basic program to reload the basic program, and an online upgrading data frame is written into the configuration memory again. According to the invention, the re-upgrading of the application program after upgrading failure is realized based on the multiple loading units, so that the reliability and safety of the system upgrading are ensured.

Description

technical field [0001] The invention belongs to the technical field of equipment online management and upgrade, and more particularly, relates to a system and method for online product upgrade based on multiple loading. Background technique [0002] After the electronic products are delivered to the factory for installation, the software needs to be upgraded after software problems are found. At present, if there are unexpected factors such as sudden power failure, sudden cable disconnection and upgrade failure during the current general online upgrade process, the product still needs to be disassembled. Electronic products are generally inconvenient to disassemble, and disassembly may cause damage to the connecting cable, which greatly increases the cost and risk of software upgrades, and is not conducive to product maintenance. In addition, studies have shown that if there is a sudden power failure during the upgrade process, the uncontrollable factors of the power supply ...
