The invention discloses an integrated energy system multi-body operation scheduling method and system based on a mixed game, and the method comprises the steps: building a multi-energy cooperation system architecture based on the characteristics and energy conversion relation of each energy body in an integrated energy system, and building each energy body model; based on each energy main body model, designing a three-layer mixed game model which comprises an upper-layer master-slave game model, a middle-layer cooperative game model and a lower-layer non-cooperative game model; the three-layer mixed game model forms closed-loop linkage through information interaction between layers; and solving the three-layer mixed game model, performing benefit distribution and settlement on each energy main body based on a solving result, and realizing operation scheduling of each energy main body. According to the method, the problem that a traditional single game framework cannot cover multi-level requirements is effectively solved, and the multi-agent collaboration efficiency and the market activeness are remarkably improved.

The invention discloses a target extraction method and device for linear cultural heritage ruins and relics. The method comprises the following steps: acquiring a remote sensing image of a linear cultural heritage; inputting the remote sensing image into a network feature extractor for multi-level feature extraction to obtain shallow layer features, middle layer features and high layer features; performing target semantic enhancement on the deep features to obtain enhanced deep features; carrying out attention and fusion operation on the shallow-layer features and the middle-layer features to obtain shallow-layer fusion features and middle-layer fusion features; performing gating attention fusion and information recovery operation on the enhanced deep-layer features, the shallow-layer fusion features and the middle-layer fusion features to obtain features after information recovery; performing linear feature reconstruction on the features after information recovery to obtain reconstructed features; and inputting the reconstruction features into a segmentation head and an auxiliary divider to obtain a prediction result. The method can achieve the automatic extraction and precise recognition of the large-scale linear cultural heritage.

The utility model discloses a rotary island cabinet which comprises a base, a rotary middle layer and a top layer, the rotary middle layer is arranged between the base and the top layer, a rotary assembly is arranged between the base and the top layer, and the rotary middle layer is movably connected with the rotary assembly, so that the rotary middle layer is rotatably connected between the base and the top layer. The island cabinet is provided with the base, the rotating middle layer and the top layer, the rotating middle layer is connected between the top layer and the base through the rotating assembly, the rotating middle layer can rotate between the base and the top layer, and therefore an operator can rotate the rotating middle layer and the top layer, the island cabinet is diversified in form, and the structure is simple. Through rotation of the rotating middle layer and the top layer, each formed form also has various functions.

The application provides a memory, a programming operation method thereof, a peripheral circuit, and a storage system. The memory sequentially comprises an array common source, a bottom level, a middle level, a top level, and a bit line connected in series along a preset direction. The programming operation method of the memory comprises: performing precharge of a programming operation, comprising: providing a first voltage to the array common source and the bit line; and providing a second voltage to a programmed-state storage unit in the memory to turn on a channel in the programmed-state storage unit, wherein the programmed-state storage unit is located in at least one of the middle level and the top level; and performing a programming operation on a middle-to-be-programmed storage unit in the middle level.

This invention relates to a self-diagnostic method and system for relay protection alarms, comprising: acquiring the upper-level mapping relationship between each relay protection device and multiple abnormal alarms; acquiring the middle-level mapping relationship between each abnormal alarm and multiple fault causes; acquiring the lower-level mapping relationship between each fault cause and multiple handling measures; determining the plug-in mapping relationship between each abnormal alarm and the impact range of plug-ins; determining the interlocking mapping relationship between each abnormal alarm and interlocking types; and establishing alarm templates for each relay protection device. When a self-diagnosis detects an abnormality in a relay protection device, an abnormal alarm is sent to the dispatching terminal. The dispatching terminal obtains the alarm template based on the abnormal alarm and the relay protection device that issued the alarm, and retrieves the alarm big data model based on the alarm template and the abnormal alarm to obtain the fault cause, handling measures, fault plug-ins, and interlocking type. In this invention, when an abnormal alarm is detected, the dispatching terminal uses the alarm template to retrieve the alarm big data model to trace the alarm cause and handling measures.
