Problems solved by technology

However, this method does not combine the motion of the UAV to judge the correctness of its positioning information. When faced with long-term high-precision positioning information disturbance, it is difficult to find the abnormality of the positioning information, which may cause the UAV to collide.

Embodiment Construction

[0016] Such as figure 1 with figure 2 As shown, a speed-based unmanned boat position accuracy judgment and control system of the present invention includes navigation and positioning equipment, task processing equipment and navigation control equipment, and each equipment can communicate through RJ45 Ethernet:

[0017] The navigation and positioning equipment obtains and provides the position information of the unmanned vehicle to the task processing equipment. The navigation and positioning equipment can be the Beidou navigation and positioning system, which can obtain the position and speed information of the unmanned boat in real time, and send it to the task processing system at a frequency of 10HZ.

[0018] The task processing device judges the accuracy of the location information of the UAV based on the location information of the UAV provided by the navigation and positioning device. The task processing equipment is based on the speed V of the UAV in each fixed monit...

Abstract

The invention discloses an unmanned ship position accuracy judgment and control system based on navigation speed. The system comprises navigation positioning equipment, task processing equipment and navigation control equipment. Based on the navigation speed, the accuracy of the real-time position data of the unmanned ship is judged, and when it is determined that the position information at a certain moment is inaccurate, the task processing system sends a ship stopping instruction to the navigation control system, so that the task of the unmanned ship is finished. By the adoption of the method, when the unmanned ship faces tall and big ship shielding or complex weather or electromagnetic interference on the sea, position information provided by the positioning system is wrong, and the situation that the unmanned ship is lost and even collides is avoided.

Description

technical field [0001] The invention belongs to the technical field of position positioning of an unmanned boat, and in particular relates to a position accuracy judgment and control technology of an unmanned boat based on a speed. Background technique [0002] When the unmanned vehicle navigates autonomously at sea and performs tasks such as detection, it is widely used in the field of surface detection because of its strong adaptability and strong maneuverability. [0003] When the unmanned boat performs tasks autonomously, it relies heavily on the positioning information provided by its own navigation and positioning system, and needs to use it for mission planning. The navigation and positioning system plays a vital role in the unmanned boat. When the unmanned boat faces tall ships, complex weather or electromagnetic interference at sea, if the location information provided by the positioning system is incorrect, the unmanned boat will be lost, and serious collision risk...
