This invention discloses a data storage method and system based on a scalable multidimensional learning index structure, belonging to the field of computer data storage. This system fully utilizes storage characteristics to organize data into memory and disk, significantly reducing disk I / O with minimal memory usage, accelerating data search speed, and supporting data expansion. This invention can be applied to multidimensional data indexing, typically represented by geospatial data, meeting the need for rapid multidimensional key searching in the high-dimensional key space of such data.

This invention discloses a method, device, and system for optimizing maintenance decisions in energy storage systems based on reinforcement learning-based multi-component lifetime collaborative modeling. The method constructs a collaborative lifetime decay model for key power devices (including IGBTs and DC bus capacitors) in the energy storage converter, collects operational data in real time, and establishes a multi-state fusion method for characterizing operational health. Furthermore, it utilizes reinforcement learning algorithms to optimize maintenance strategies. By jointly modeling the lifetime recovery effect, cost, failure risk, and system stability of different maintenance behaviors, a multi-objective reward function is constructed to achieve adaptive optimization of maintenance decisions. This invention can automatically determine the timing of overhaul or preventative maintenance based on the equipment's operating status and aging condition, eliminating the need for fixed-cycle manual maintenance, effectively reducing failure rates and maintenance costs. This invention is applicable to intelligent operation and maintenance and state management scenarios for energy storage converters.

The invention relates to a video transmission system based on real-time performance optimization detection, comprising: a first transmission link in which a distributed system encoder encodes an image into a network flow signal, a distributed system decoder decodes the network flow signal to extract the image frame by frame, and performs OCR identification on each frame of image to identify a timestamp on the image, recording corresponding timestamps during decoding when the image frames are decoded, and calculating difference values of the timestamps related to the same image; the desktop screen capture client of the second transmission link encodes an image containing a timestamp into a network flow signal, the network flow signal is decoded by the centralized system processor, the image is extracted frame by frame in the decoding process, and OCR identification is carried out on each frame so as to identify the timestamp on the image and record the timestamp during decoding when the image frame is decoded; calculating each timestamp difference value related to the same image; and the comprehensive management and control platform is used for switching the transmission links. According to the invention, the capability of a video transmission system can be developed to the greatest extent.

The utility model relates to the technical field of electric power safety maintenance, and discloses a warning fence for electric power safety maintenance, which comprises a connecting main rod, a clamping groove is arranged on the surface of the connecting main rod, and two C-shaped clamping sleeve shells are attached inside the clamping groove. According to the warning fence for electric power safety maintenance, sliding blocks fixedly connected with two sets of connecting plates slide in limiting grooves formed in connecting main rods, the two connecting plates are attached in the sliding process, and then linkage plates are used for conducting linkage clamping on mounting screws on the side faces of the two connecting plates; and then the two mounting screws are respectively fastened in a threaded mode through the mounting nuts, then pressing and limiting operation is formed on an assembly formed by C-shaped clamping sleeve shells fixedly mounted on the connecting cross rods at the tops of the two auxiliary supporting rods, in the whole operation process, the overall supporting range can be widened, multiple auxiliary supporting points can be formed, and the supporting efficiency is improved. And therefore, the overall stability can be improved, and the toppling phenomenon is avoided.
