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 solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0033] The present invention is a technical method researched for the provincial dispatching system in the electric automation system that needs to remotely read the warning information of the local survey. This method is also applicable to the remote survey between the local surveys. For the sake of simplicity, the active access system is called the upper-level system, and the corresponding passive access system is called the lower-level system.

[0034] In order to minimize the alarm information of inter-system synchronization, the bandwidth of inter-system synchronization is large, and the alarm information will not be lost when some nodes or communication links fail, the present invention pr...

Abstract

The invention discloses a method and a device for remotely reading alarm information of a power automation system. The method mainly provides a technical solution for a superior system in the power automation system to remotely view abnormal alarm information in a subordinate system. The invention adopts the mechanism of load balance and safe box, increases the transmission bandwidth, reduces thedata transmitted synchronously, improves the reliability of transmission, and ensures the alarm information not to be lost under the condition of partial node failure.

Description

technical field [0001] The invention relates to the technical field of remote data synchronization, and more specifically, relates to a method and device for remote access to alarm information of an electric power automation system. Background technique [0002] In the power automation system, each system notifies users of various abnormal conditions through alarms. And there is a situation where the upper-level system needs to check the abnormal alarm in the lower-level system. For example, the Jiangsu dispatching control system (deployed in Nanjing) needs to check the alarms of the Zhenjiang dispatching control system. This requires the remote transmission of alarm information from Zhenjiang to Nanjing. How to ensure the minimum amount of information transmitted 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 existing rem...
