Problems solved by technology

The course autopilot cannot realize the track tracking control of the ship. Even if the ship's course control is realized, manual intervention is always required, which is far from the true meaning of the ship's autonomous navigation control measures

Embodiment Construction

[0031] In order to better understand the technical features, technical content and technical effects of the present invention, the accompanying drawings of the present invention will now be described in more detail in conjunction with the embodiments.

[0032] Below in conjunction with accompanying drawing and embodiment the patent of the present invention is further described.

[0033] Such as figure 2 As shown, the present invention provides a ship autonomous navigation control system, including a navigation control computer, a course speed control board, an engine, a rudder angle actuator, GPS and attitude measuring equipment, a rudder, and a rudder angle sensor;

[0034] The navigation control computer receives the speed command and the discrete expected track point sequence through the network, receives the ship position and ship attitude information sent by the GPS and the attitude measurement equipment through the RS232 serial port, and performs the course control loop...

Abstract

The invention provides a ship autonomous navigation control system and method. Aiming at function loss of an autopilot and the use limitations of a track autopilot, the system and method avoid a continuous expected navigation track. The method can meet the demands of the autonomous navigation tracking control of a chip through employing a series of key discrete points of the expected navigation track. The method does not need manual intervention, can be widely used for solving a problem of autonomous navigation control of the ship in an unattended environment, and is especially suitable for the autonomous navigation of the ship in the occasions of a water surface target field and high-danger water regions. The method irons out the defects of the functions of a navigation autopilot, approaches the tracking control performance of the track autopilot, but does not need to enable a continuous expected navigation track to serve as tracking input. Compared with a conventional method of navigation tracking control, the method is high in engineering operability and implementation performance, and can be widely used for meeting the demands of autonomous navigation control of the ship.

Description

technical field [0001] The invention relates to a ship autonomous navigation control system and control method, belonging to the technical field of ship automatic control. Background technique [0002] For surface ships navigating on sea or inland rivers, they often need to navigate autonomously according to the preset track to complete specific navigation tasks. For example, surface ships need to navigate autonomously along the coastline to perform terrain survey, mine clearance, water quality sampling, visual monitoring, etc. The task; another example is that the target ship needs to navigate autonomously according to the designated track, simulating the water surface target with moving characteristics, for the target missile to be used. Such missions require ships to have unattended autonomous navigation capabilities. [0003] Track autopilot is a theoretical solution for track tracking control of surface ships, which is used to track and maintain the set route. This tr...
