Software online upgrading method based on upper computer and lower computers

Abstract

The invention provides a software online upgrading method based on an upper computer and lower computers. The software online upgrading method based on the upper computer and the lower computers is characterized in that the upper computer is used for sending pre-upgrade data to a network through a broadcast communication mode, and all the lower computers based on the network are responsible for receiving the pre-upgrade data, judging the validity of the received pre-upgrade data and writing valid data to assigned addresses until all the needed data are received completely, namely, online upgrading operations are carried out on the corresponding lower computers. In this way, under the condition that a large amount of embedded type system software in the lower computers needs to be upgraded online at the same time, compared with a one-to-one upgrading mode in the prior art, the software online upgrading method based on the upper computer and the lower computers can greatly save upgrading time and thus improve online upgrading efficiency.

Description

technical field [0001] The present invention relates to an online software upgrade method based on a host computer and a lower computer, in particular to a method for solving the problem of how to upgrade embedded system software through broadcast communication when a large number of embedded system software needs to be upgraded online at the same time. The online software upgrade method based on the upper computer and the lower computer is based on the problem of software online upgrade efficiency. Background technique [0002] In order to keep the software, data and other information in the embedded system in the latest state, it is necessary to upgrade and maintain the embedded system software in real time. However, when upgrading a large number of embedded system software online, the upgrade speed is very fast Slow, unable to meet the needs of real-time updates, affecting customer use.

Problems solved by technology

[0002] In order to keep the software, data and other information in the embedded system in the latest state, it is necessary to upgrade and maintain the embedded system software in real time. However, when upgrading a large number of embedded system software online, the upgrade speed will be very fast Slow, unable to meet the needs of real-time updates, affecting customer use

[0003] The embedded system online upgrade method currently used in the industry is a point-to-point upgrade, that is, when the embedded system software in the first lower computer is successfully upgraded, the second one is upgraded, and the embedded system software in all lower computers is upgraded sequentially. In this upgrade method, when the number of lower computers to be upgraded is large, that is, when there are many embedded system software, the upgrade time will be very long, which cannot meet the real-time update requirements of embedded system software.
