Benefits of technology

This technology uses various techniques such as file compression or encryption to improve efficiency when transferring large amounts of data between systems over long distances without losing any important details about how they were being used up again later on.

Problems solved by technology

This patented describes an example problem with distributing applications that require remote access from different areas within their own organization's control center (COC). When one part fails due to some reason like being out for work, it needs to recover its previous status without affecting other parts working properly. However, current methods have limitations when trying to restore these capabilities after failures during maintenance operations.

Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0020] The system running status detection module cyclically detects whether the system application in this area is running in the disassembled state. If the condition is not met, it will continue to detect. After the condition is met, the data cache module will be started; the data cache module is divided into historical sampling data cache module, Historical alarm record cache module, manual operation data cache module: The historical sampling data cache module is automatically triggered after the system is unloaded; when the system time reaches the historical sampling time point, the historical sampling data cache module obtains all plant station information in the area from the model library list, obtain all the measuring points and their station information from the model library, and form a sampling point information queue; the historical data cache module circulat

Abstract

The invention discloses a data caching method in a disconnection state of the distributed application of a power dispatching automation system, which is characterized by comprising the following steps of: (1) circularly detecting whether the application of a local system operates in the disconnection state or not by a system operating state detection module, continuously detecting if conditions are not met, and starting a data caching module after the conditions are met, wherein the data caching module includes a historical sampling data caching module, a historical alarm record caching module and a manual operation data caching module according to different caching data types; (2) caching plant station data administrated in a disconnection area, and generating a historical sampling data file; (3) increasing a disconnection label in the content of alarm information during disconnection, and generating a historical alarm record into a data file; and (4) caching various operation information into a local real-time library by adopting different storage modes through the manual operation data caching module. The invention can effectively prevent the loss of system application data during the disconnection, thereby ensuring the integrity of the data.
