Problems solved by technology

But the limitation of this method is that the bandwidth of a proxy node is limited by the bandwidth of the server network card
The error retransmission method is not applicable to messages transmitted in the system in the form of multicast, such as alarms, because the multicast in the past period no longer exists, and it is only applicable to data transmission in files or databases

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0033] The invention is a technical method researched for the provincial dispatching system in the electric power automation system that needs to remotely read the alarm information of the geostationary inspection, and the method is also applicable to the remote inspection between the geostationary inspection and the geostationary inspection. For the sake of simplicity, the system that actively refers to is called the upper-level system, and the corresponding system that refers to passively is called the lower-level system.

[0034] In order to minimize the alarm information synchronized between systems, the bandwidth of synchronization between systems is large, and the alarm informa...

Abstract

The invention discloses a method and device for remote access to alarm information of an electric power automation system. The method mainly provides a technical solution for an upper-level system in an electric power automation system that needs to remotely view abnormal alarm information inside a lower-level system. The invention adopts the load balancing and safe mechanism, increases the transmission bandwidth, reduces the synchronously transmitted data, improves the reliability of the transmission, and can ensure that the alarm information will not be lost even in the case of partial node failure.

Description

technical field [0001] The invention relates to the technical field of remote data synchronization, and more particularly, to a method and device for remote retrieval of alarm information of an electric power automation system. Background technique [0002] In the power automation system, each system notifies users of various abnormal situations through alarms. And there is a situation where the upper-level system needs to check the abnormal alarms in the lower-level system. For example, the Jiangsu dispatching control system (deployed in Nanjing) needs to check the alarms of the Zhenjiang dispatching and control system. This requires the remote transmission of alarm information from Zhenjiang to Nanjing. How to ensure that the amount of transmitted information is minimal and the transmission is stable and reliable is the key point to ensure remote access to alarm information. [0003] When solving data synchronization and synchronization reliability problems between exis...
