Embodiment Construction

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0027] Glossary:

[0028] SOE: Event Sequence Recording, the abbreviation of Sequence Of Event, is mainly used to record the accurate time of multiple switch input signal displacements when an accident occurs, so as to distinguish the sequence of multiple displacements. It is a time stamp with synchronous time stamp The switch value input displacement event information. Each piece of SOE information is composed of 8 bytes, which are 1-byte binary input variable information and 7-byte CP56time2a time information.

Abstract

The invention discloses an SOE information management method and a storage device thereof. The method comprises the steps of storing SOE information in a cyclic data storage area, the storage contentof each piece of SOE information comprises time scale information and a flipping character, the flipping character represents the number of times that the cyclic data storage area is covered, and thelength of the space occupied by the flipping character is smaller than the length of the space occupied by the time scale information; and traversing the SOE information according to an address sequence from a starting address to an ending address of the cyclic data storage area, searching different flipping symbols, and determining the SOE information stored at the earliest time. The embodiment of the invention at least has the following beneficial effects: the calculation amount and the space occupation during comparison are reduced, the CPU processing time is reduced, and the processing efficiency is improved, so that the safe and effective operation of the low-performance power grid equipment is ensured.

Description

technical field [0001] The invention relates to the field of intelligent power distribution, in particular to a method for managing SOE information and a storage device thereof. Background technique [0002] SOE is the sequence of events record, the abbreviation of Sequence Of Event, which is mainly used to record the accurate time of multiple switch input signal displacements when an accident occurs, so as to distinguish the sequence of multiple displacements. The switch value input displacement event information. Each piece of SOE information is composed of 8 bytes, which are 1-byte binary input variable position information and 7-byte CP56time2a time information. [0003] The existing method for obtaining the earliest stored SOE information is to sort the CP56time2a time stamps of all data according to the SOE data format after reading all the data. With the increase of equipment commissioning time, there are more and more SOE records, even reaching hundreds or even tho...
