The present invention proposes a method for minimizing the time delay of sensing data acquisition by dynamically scheduling unmanned terminals, including: step 1, the main process of the base station sets up a distributed priority experience multiplexing pool and initializes the data acquisition time delay of all sensors; step 2, The base station starts the sub-process to simulate the acquisition delay of unmanned terminal trajectory data and uploads it to the distributed priority experience multiplexing pool; step 3, the base station uses the quantile error matrix algorithm to solve the minimum sensing data acquisition delay based on the distributed priority experience multiplexing pool The optimal trajectory; step 4, the base station sends the optimal trajectory dynamic mobilization command to the unmanned terminal to obtain the latest data of the sensors in the sensing area. The technical solution of the present invention can dynamically schedule unmanned terminals through the base station, and quickly explore unknown situations in the mobile crowd sensing technology scene, thereby speeding up the speed of strategy optimization and improving the effect of minimizing the time delay of sensing data acquisition.
Description
technical field [0001] The invention belongs to the field of mobile unmanned crowd intelligence perception, and in particular relates to a method for minimizing the time delay of sensing data acquisition by dynamically scheduling unmanned terminals. Background technique [0002] Mobile crowd sensing technology supports the demand for sensing data acquisition in smart city scenarios. This technology uses crowd intelligence to collect a large amount of data in urban environments, and has high practical application value in traffic monitoring, natural disaster warning and other issues. . In recent years, unlike the traditional crowd sensing technology that is human-centered and uses portable terminals (such as iPhone, iWatch) as tools, the mobile unmanned crowd intelligence technology centered on mobile unmanned terminals (such as drones and unmanned vehicles) Perception technology can provide smart cities with wider application and higher quality perception data acquisition s...
