Abstract

The embodiment of the present invention discloses a ship follow-up operation auxiliary driving method and system, which relate to the technical field of ship operation and are invented for the convenience of improving the accuracy of ship control. The ship follow-up operation assisted driving method includes: obtaining the current course, steering rate and navigation speed of the ship; calculating the predicted time it takes for the ship to travel from the current position to the distance indicator line in front according to the current navigation speed; based on the current course, The steering rate and the predicted duration are used to calculate the predicted course when the ship reaches the distance indicator line in front; the current position of the ship is connected to the intersection point of the predicted course and the distance indicator line ahead to form the predicted navigation of the ship trajectory; displaying the predicted navigation trajectory on the display screen. The invention is suitable for follow-up operation of ships.

Description

technical field [0001] The invention relates to the technical field of ship operation, in particular to a method and system for ship follow-up operation to assist driving. Background technique [0002] Modern ships are generally equipped with autopilots, with automatic and follow-up modes. In the course mode of the autopilot, the driver only needs to input the set course, the autopilot completes the control process, the rudder process is carried out by the autopilot independently, and the ship enters the maintenance stage after the course reaches the set course, without additional intervention by personnel. [0003] However, in the follow-up mode, when the course needs to be changed, the helmsman or driver roughly judges how many degrees of rudder need to be turned based on the experience of the ship, manually turns the rudder, and then waits for the ship to turn to the vicinity of the target course before returning to the rudder. The whole process is manually controlled by...
