Abstract

The invention discloses a remote dynamic upgrading method and method for embedded software of a power system. The method comprises the steps of remotely loading a software upgrade information table and a software upgrade code to the power system's equipment node to be upgraded; when an 'idle' task runs in the equipment node (all system tasks are idle), performing information check on the softwareupgrade information table, and executing dynamic software upgrading if the information check shows a positive result. Through information check and interruption control, a software upgrading process of good safety and reliable is guaranteed.

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. At p...
