Distributed software upgrade system and method

Abstract

The invention discloses a distributed software upgrade system and method under the industrial control equipment application environment, and solves the problem that in the same stage, in the upgrade of different versions of application software in different types of industrial control equipment client terminals, the workload of maintenance staff is huge in the prior art. The distributed software upgrade method comprises the following steps: current version information and software version information in an industrial control equipment client terminal are stored in an access server with the same network segment; through the access server, the current version information and the software version information are forwarded to a version management server; the version management server queries a software version database to decide whether to upgrade or not, and returns the information that whether the upgrade is required or not to the industrial control equipment client terminal through a local access server; if the upgrade is required, an upgrade demand is received, upgrade information is acquired, an upgrade program is downloaded according to the upgrade information, the upgraded information is returned, and the situation whether the upgrade is successful or not is determined according to the returned information. The distributed software upgrade system and method provided by the invention can reasonably use a server source, thereby reducing the workload of the software maintenance staff.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a distributed software upgrading method. Background technique [0002] As my country's computer industrial control software brings more and more perfect functions to users, software users have to upgrade software from time to time. Most of the current software upgrade methods use the industrial control instrument client to achieve remote upgrade, that is: the computer software provider stores the latest version of the computer software upgrade data on the server or the industrial control instrument client locally, and the user of the industrial control instrument client uses HTTP via the Internet. Namely (Hyperlink Transfer Protocol) or FTP (File Transfer Protocol) to directly download the required upgrade data from the server. This software upgrade method is suitable for upgrading the client application software of the same type of industrial control instrument in the same...
