The invention discloses a video content retrieval method and device based on television system voice interaction and a terminal, and relates to the technical field of video processing, and the method comprises the steps: when a video is played for the first time, extracting a picture frame from the video at a preset frequency, converting the picture frame into a multi-dimensional image feature vector and a corresponding video timestamp, and carrying out hierarchical storage in a database, constructing vectorized data containing visual semantic information; obtaining a voice retrieval instruction, performing intention recognition and semantic understanding, extracting a detection keyword, and generating a multi-dimensional retrieval feature vector; calculating a matching degree between the multi-dimensional retrieval feature vector and a multi-dimensional image feature vector of a video picture frame stored in a database, and screening out picture frames of which the similarity is higher than a preset similarity threshold to form a retrieval candidate matching set; and determining matched picture playing. The video content retrieval method is efficient, accurate and high in interactivity, and retrieval experience and operation efficiency of the user in the video watching process are remarkably improved.

This utility model discloses a classified advertising map booklet, including a mounting plate. A binding strip is installed in the middle of the mounting plate, and multiple map booklet pages are mounted on the front end of the mounting plate via the binding strip. Damping hinges are installed at both the upper and lower ends of the mounting plate, and an upper baffle is movably mounted on the upper end of the mounting plate via the damping hinges. This classified advertising map booklet provides storage and protection for the map booklet pages, preventing wear and tear when not in use. It also provides illumination for the map booklet pages, making it easier to browse. The mounting plate supports the map booklet at different angles, facilitating browsing from various angles. It simultaneously provides storage protection, illumination, and angle support for the advertising map booklet. The mounting plate can move up and down around a mounting sliding plate, allowing for vertical position adjustment after installation, making the advertising map booklet more convenient for various installation and use.

The invention discloses a gridding expansion method and device for overlapped interest points of a map, a medium and a program product, and the method comprises the steps: receiving input parameters which comprise a reference center point, a to-be-expanded interest point list and a minimum expansion distance; according to the total number of the to-be-expanded interest points in the to-be-expanded interest point list, determining the grid row and column number of the expanded grid, and aligning the grid center point of the expanded grid with the reference center point; traversing the to-be-expanded interest point list, and determining target row and column numbers of the to-be-expanded interest points in the expanded grid according to the index of each to-be-expanded interest point; obtaining a target offset of the to-be-expanded interest point relative to the grid center point according to the target row and column number and the minimum expansion distance; according to the target offset, obtaining unfolding longitude and latitude coordinates of the to-be-unfolded interest point; and finally, updating the to-be-expanded interest point list by utilizing the expanded longitude and latitude coordinates to obtain a gridding expanded interest point list. According to the method, the map overlapping interest points are clearly and completely displayed.

The method comprises the following steps: in response to a preset interaction operation on a first preset interaction region, a preset control is displayed on the first preset interaction region, the first preset interaction region comprises a preset interaction region corresponding to target first media content in a first media content stream, the preset interaction region is used to display and / or publish associated information of media content corresponding to the preset interaction region, in response to a trigger operation on the preset control, a second media content stream is displayed, wherein the second media content in the second media content stream has a preset association relationship with the target first media content, and / or the associated information of the second media content satisfies a first preset condition. Through the above technical solution, the interactive function based on media content is enriched, and the media content browsing experience is improved.

The invention particularly relates to a nuclear power plant operator station time sequence data access method based on an Internet of Things time sequence database, and belongs to the field of industrial time sequence databases, and the method comprises the following steps: S1, data collection: obtaining time sequence data from a data server, and temporarily storing the time sequence data in a shared memory through a hash table; s2, storage optimization: obtaining time sequence data from the shared memory, and writing the data into an Internet of Things time sequence database by adopting a batch insertion mode; and S3, query service: providing a query interface at an operator station, responding to a query request, retrieving time sequence data from the time sequence database of the Internet of Things, and returning the time sequence data. The invention further relates to a nuclear power plant operator station time sequence data access device based on the internet of things time sequence database, computer equipment and a storage medium. According to the invention, efficient storage, efficient compression and efficient reading of the time series data are realized.
