An automatic light tracking device and method for dangerous targets used in night navigation of ships

Abstract

The invention relates to an automatic danger object light tracking device and method used for ship night navigation. The automatic danger object light tracking device comprises a signal collection unit, a timer, a signal processing unit and a lamp holder control unit, wherein the signal collection unit comprises a shipborne ARPA radar, a ship cab sensor and an AIS terminal; the timer is used for collecting pulse signals of two rotary encoders in the horizontal direction and the vertical direction of a lamp holder in a counting mode; the signal processing unit is used for obtaining the current rotation position of the lamp holder according to information of the signal collection unit and the pulse signals of the timer and obtaining the horizontal and vertical angles by which a searchlight needs to rotate relative to the current position; the lamp holder control unit is used for controlling the horizontal and vertical rotation of the whole lamp holder according to output information of a single-chip microcomputer. The automatic danger object light tracking device and method used for the ship night navigation solve the problem that current shipborne collision prevention and navigation equipment is not convenient to use and is not visual, the large-power searchlight is adopted to automatically locate and track dynamic objects possibly collided with a ship in time, and the possibility that sailors ignore potential collision risks is reduced.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an automatic light tracking device and method for dangerous targets used for night navigation of ships. Background technique [0002] In recent years, my country's inland shipping industry is in a new period of prosperity and development, both in terms of the number of ships and the tonnage, has developed by leaps and bounds, but the accompanying safety problems of ship navigation are also becoming more and more serious. The safety of ship navigation mainly refers to whether the ship has collision, damage, grounding and other problems during navigation. In order to avoid such accidents that threaten the safety of ships, inland water ships are generally equipped with AIS systems, ARPA radars, and VHF communication equipment to assist Ship navigation and collision avoidance. However, the functions of these systems and equipment are not very obvious to experienced sailors and crew du...

AI Technical Summary

Problems solved by technology

However, the functions of these systems and equipment are not very obvious to experienced sailors and crew during the daytime. They can make reasonable operations such as slowing down and turning the rudder in case of possible collisions based on experience to avoid threatening the safety of the ship. At the same time, at night, visibility is reduced, and the helmsman's dependence on AIS terminals, radar and VHF communication equipment has increased sharply. However, it is extremely inconvenient to go to and from these equipments, even if these equipments can provide accurate Information Usually the crew also needs to use high-power searchlights to illuminate the corresponding direction to confirm
