Problems solved by technology

[0003] The current path planning methods are mainly divided into two categories, namely heuristic methods and deterministic methods. Heuristic methods are often used to speed up finding the optimal solution, which has a large amount of calculation and a long calculation time, and generally does not follow the Strict search process, so the calculation results are random, generally used in occasions where real-time requirements are not high

Embodiment Construction

[0018] The present invention uses the improved A* algorithm for global path planning, provides the shortest global optimal path for the navigation observation of the wave glider, and improves the efficiency of the wave glider in performing tasks. The improved A* algorithm belongs to the heuristic algorithm. The path distance is used as a cost function for path search, and the improved A* algorithm has shorter calculation time, less calculation amount and better path.

[0019] Wave glider devices such as figure 1 As shown, the wave glider is a two-body structure, and the communication system and the sensor system are loaded on the floating body, and the tractor uses the buoyancy provided by the floating body to drive it forward by waves. When the wave glider needs to perform navigation tasks, the wave glider obtains the current position through the GPS module on the floating body ship, communicates through the shore-based monitoring system, and obtains the position information ...

Description

technical field [0001] The invention relates to a global path planning method for a wave glider, in particular to the field of autonomous navigation observation of a wave glider. Background technique [0002] The wave glider is an unmanned autonomous vehicle that uses its special double-body structure to convert wave undulations into forward power. It is mainly composed of three parts: floating body vessel, umbilical cable and traction machine. The multi-rigid body structure composed of the above three parts is used to convert wave energy into forward power, and the solar panels on the floating body ship are used to provide energy supply for the navigation, communication and motion control modules of the wave glider. It has the functions of long-term continuous navigation, autonomous navigation and positioning, artificial intelligence identification, etc., and can realize continuous navigation of 10,000 kilometers in one year at a speed of 0.5-1 m / s without energy supply, t...
