Power system embedded software remote dynamic upgrade method and system

Abstract

The invention discloses a method and system for remote dynamic upgrading of embedded software in a power system, which includes the following steps: remotely loading a software upgrade information table and a software upgrade code to a device node to be upgraded in the power system; when the device node " When the "idle" task is running (when all system tasks are not running), the information is verified according to the software upgrade information table, and if the verification is correct, the software dynamic upgrade is performed. The invention ensures the safety and reliability of the software upgrading process through the control of information verification and interruption.

Description

technical field

[0001] The invention belongs to the field of equipment remote software upgrade, in particular to a method and system for remote dynamic upgrade of embedded software in a power system. Background technique

[0002] The power system has the characteristics of high reliability, high stability, and high continuous operation. Embedded software is widely used in the power system industry. The reliability of embedded software in some important links (such as relays, nuclear power plants, etc.) is important for the stability of power systems. Operation is of great significance. Abnormal operation will often cause large economic losses and even casualties. Moreover, with the continuous emergence of new technologies and the continuous improvement of equipment function and performance requirements, it is necessary to regularly or irregularly upgrade the internal embedded software of these power equipment to prolong the service life of the equipment and save costs.
