Photoelectric guide emulation system for ship

Abstract

The present invention discloses a photoelectric guidance simulation system, for the landing on a warship, consisting of a control computer, an inertial navigation system, an infrared detection gyro stabilizing system, infrared cooperation targets, a linear motion unit, an electric motor, a motion controller and a ground control station. The infrared detection gyro stabilizing system realizes stabilization of an optical axis; five cooperation targets are provided on a sliding block of the linear motion unit, and the motion controller controls the motion of the linear motion unit to bring the cooperation targets to move upward and downward and to simulate the motion of the runway decks in a vertical direction under the function of ocean waves. An infrared camera in the infrared detection gyro stabilizing system obtains images of the simulated runway decks generated by the infrared cooperation targets; operators at the ground control station identify and lock the simulated runway decks according to the image when the simulated runway decks are detected by the infrared detection gyro stabilizing system. The infrared detection gyro stabilizing system processes the five images of the simulated runway decks and sends necessary image information to the control computer which calculates a motion characteristic of the warship and a landing point position by using a photoelectric guidance algorithm. The photoelectric guidance simulation system with high precision and low cost has an important value for the development and manufacture of the photoelectric guidance landing systems.

Description

technical field [0001] The invention relates to a ship landing photoelectric guidance simulation system, which is suitable for the engineering realization of simulating the landing of an aircraft on a deck runway of a ship. Background technique [0002] Landing an aircraft on a ship is more difficult than landing on the ground. During the landing process, the aircraft must maintain an ideal glide angle of about 4°, and must stop and land on the designated area on the deck. The traditional Fresnel light box guidance method is visible light guidance, which has a complex structure, high cost, and cannot provide accurate landing information. When in a high-level sea situation, the pilot cannot observe the guidance Fresnel light box information, and does not have all-weather guidance capabilities. In addition, changes in the vertical height of the hull's pitch and sinking of more than 1.25 meters will cause the corresponding landing point to move back and forth more than 18 mete...

Problems solved by technology

[0003] The problem solved by the technology of the present invention is: when the traditional guidance method is in a high-level sea situation, the pilot cannot see the guidance signal clearly, and when the pitch and ups and downs of the ship are relatively large, they cannot stop at the designated area on the deck, resulting in landing If the failure causes a go-around or even an accident, provide a high-precision, all-weather, low-cost ship landing photoelectric guidance simulation system, which is used to predict the ship's movement law and the position of the ship's landing point, and realize autonomous ship landing
