Robot welding path planning method based on firework particle swarm optimization algorithm

ActiveCN109542103AIncrease population diversityImprove search efficiencyAdaptive controlPosition/course control in two dimensionsGaussian mutationPlanning approach
The invention provides a robot welding path planning method based on a firework particle swarm optimization algorithm, belonging to the technical field of robot welding control. The method comprises the following steps of: using a greedy algorithm to initialize all path solutions and parameters of the population; updating the speed and position of all population individuals according to the particle swarm operator; taking the individual of the particle swarm as a firework of the firework algorithm; generating sparks by modifying a blast operator and a Gaussian mutation operator; selecting firework populations by using an elite-roulette strategy; rebuilding the population by using a dual population strategy; and updating the individual historical optimal solution and the global optimal solution to obtain an optimal welding path. According to the robot welding path planning method based on the firework particle swarm optimization algorithm, the population diversity of the particle swarmis enhanced, information interaction among the firework algorithm individuals is achieved, and the optimal welding path is obtained by combining the particle swarm optimization algorithm with the firework algorithm, and the effectiveness and feasibility are high.

Method and device of operation on audio/video file based on voiceprint information

The invention discloses a method of an operation on an audio or a video file based on voiceprint information. The method of the operation on the audio or the video file based on the voiceprint information comprises the following steps: collecting the voiceprint information of a vocalization objective; and searching the audio or the video file according to the voiceprint information. The invention further provides terminal equipment. According to the method and the device of the operation on the audio or the video file based on the voiceprint information, the audio or the video file can be categorized according to the voiceprint information of a specific contact, when a user wants to find the audio or the video file which contains the specific contact, the files do not need to be played and checked one by one, just a direct selection is needed, thus the user can easily find out the audio or the video file which contains the voice of the specific contact. In addition, with the help of the method and the device of the operation on the audio or the video file based on the operation of the voiceprint information, the audio or the video file is capable of directly skipping to a speaking time node of a certain contact in the audio or the video file and playing so that search efficiency can be improved for the user.

View interface resource management method and apparatus

The application discloses a view interface resource management method and apparatus. The method comprises the steps of: by a dynamic view container or a basic view for forming a view interface, acquiring a notification that a coordinate position of a visible region on a reaction screen in the view interface is changed, and transmitting the notification to an alternative view; according to the notification, by the alternative view, comparing a coordinate position of the alternative view in the view interface with the coordinate position of the visible region, and judging whether the coordinate position of the alternative view is in the coordinate position of the visible region; if yes, loading and rendering the alternative view; and if no, recovering memory resources occupied by the alternative view. By adopting the method provided by the application, an observer mode is adopted, and the view interface which is of a tree-shaped structure is regarded as a view interface which is of a flat structure, so that the coordinate position of the alternative view in the view interface can be reversely calculated from leaf nodes to root nodes, search efficiency can be improved and a calculation quantity can be effectively reduced, and thus, an effect of saving calculation resources is achieved.

Method and device for achieving fast searching of business information

This application provides a method and device for achieving fast searching of business information. The method comprises the following steps that a new operation log generated by a business database is monitored, wherein the storage structure of business data in the business database is in a table division storage mode; business data in a middle database is updated according to the operation log, wherein the storage structure of the business data in the middle database is in a single table storage mode; the business data in the middle database is updated to a search database, wherein the storage structure of business data in the search database is the same as that of the business data of the middle database, and the search database provides database services for searching the business information. According to the method and device for achieving fast searching of the business information, the search database with the single table storage structure is adopted to provide search services of the business information, the search efficiency of the business information can be greatly improved, at the same time, the storage structure of the business database does not need to be modified, the business data is processed and maintained conveniently.
