[0002] Alarm information processing is an important part of dispatching daily monitoring. With the expansion of power grid scale and the needs of integrated large-scale dispatching operation, the traditional alarm information display method can no longer meet the current operation requirements.
When an accident or abnormality occurs, a large number of alarm signals appear in the alarm interface of the dispatching automation system, and the operator often has no time to deal with these alarm information and will be washed away by the new alarm information. Even in the non-accident state, daily operation The maintenance alarm information will also make the operating personnel overwhelmed

Embodiment Construction
[0015] 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.
[0016] In the existing technology, limited by the operating environment of the hardware and the power dispatching control system, the buffer space that can be occupied by real-time alarm processing is limited. When a large number of alarm information emerges, the alarm information that enters the buffer space first will be discarded. The content will be constantly refreshed in real time, and dispatching and monitoring personnel will not be able to browse the flushed alarm information in the alarm information display window and deal with it in a timely manner.
[0017] In order to enable users to consult historical alarm information, the alarm information dynamic display method based on the dispa...

The invention discloses a dynamic display method for alarm information based on a dispatching control system. A real-time cache queue and a history cache queue are established, both of the real-time cache queue and the history cache queue are based on a principle of first in, first out. When new alarm information occurs, the alarm information is stored in the real-time cache queue and a historicalalarm library, and the alarm information is pushed to an alarm display window to display, and the alarm information that is flushed out in the real-time cache queue is stored in the history cache queue. When a user needs to view the historical alarm information in the alarm display window, the alarm information is read from the history cache queue and the information is displayed in the alarm display window. When the number of alarms in the history cache queue cannot meet user's requirements, the alarm information is read from the historical alarm library and is displayed in the alarm displaywindow. Through using a double buffering mechanism and a dynamic real-time loading data strategy, the method can realize that monitoring personnel can conveniently and rapidly browse concerned alarminformation in the alarm display window.
Description
technical field [0001] The invention relates to a dynamic display method of alarm information based on a dispatch control system, which is suitable for a power control system and belongs to the technical field of power dispatch automation. Background technique [0002] Alarm information processing is an important part of dispatching daily monitoring. With the expansion of power grid scale and the needs of integrated large-scale dispatching operation, the traditional alarm information display method can no longer meet the current operation requirements. When an accident or abnormality occurs, a large number of alarm signals appear in the alarm interface of the dispatching automation system, and the operator often has no time to deal with these alarm information and will be washed away by the new alarm information. Even in the non-accident state, daily operation The maintenance alarm information will also make the operating personnel overwhelmed. Therefore, it is necessary to...
