Optronic two-channel auto-observation following semi-submerged device

Abstract

The invention relates to a photoelectric double-channel automatic watching following semi- diving device, belonging to ship engineering technical field, comprising a casing, vertical and horizontal tail fins, reversible screw propeller, top frame, connection pipe, vent-pipe, power system, vertical and horizontal tail fin executer, photoelectric periscopic window, signal processing encryption and decryption machine, transmitting and receiving energy exchange base array, hydraulic sensor, control system, air compressing bottle, rapid blow valve, ballast tank, water injection system, and water injection valve. The semi-diving device can be completely hidden underwater and can only expose the periscopic window for detecting and encrypts the detected image signal and transmits it in form of water sound wireless signal to the underwater mother boat. The encrypted control instructions emitted by the underwater mother boat are transmitted to the semi-diving device in the data transmission form of water sound digital communication and command the semi-diving device to work after decrypted. The encrypted water sound wireless signal is unable to be modified, broken down, intercepted or utilized by the enemy and can be widely applied to military and civil occasions and the others.

Description

technical field [0001] The invention relates to a submersible, in particular to a photoelectric dual-channel automatic lookout-following semi-submersible whose main body can be submerged underwater and only exposes the periscope window for detection, and can fully submerge underwater and concealed. It belongs to the marine engineering technology The range of underwater monitoring and control boats in the field. Background technique [0002] The submersibles currently in use need to extend the periscope when they rise close to the water surface in order to detect the situation around the sea surface, which is easy to expose their own targets; Transmitted to the submersible, it is easy to be discovered and destroyed by the enemy, and it is also easy to expose the target of the mother submersible that tows it; the utility model patent of "buoy-type photoelectric camera lookout platform" with application number 02275002.7, which places the photoelectric camera on a On the non-m...

[0002] The submersibles currently in use need to extend the periscope when they rise close to the water surface in order to detect the situation around the sea surface, which is easy to expose their own targets; Transmitted to the submersible, it is easy to be discovered and destroyed by the enemy, and it is also easy to expose the target of the mother submersible that tows it; the utility model patent of "buoy-type photoelectric camera lookout platform" with application number 02275002.7, which places the photoelectric camera on a On the non-metallic streamlined buoy, the platform and the camera on it are connected to the submarine with a traction rope, power cord, video cable, and control cable, and the video signal is converted into a digital signal and then transmitted to the submarine through the cable. It is also the main body that must protrude from the water surface The detector has poor concealment, is easy to be discovered and destroyed by the enemy, and is easy to expose the target of the mother submersible that tows it; the invention patent of "underwater GPS positioning and navigation method and system without high stability frequency standard" with application number 200310118440.9, issued by GPS satellite constellation, more than four GPS buoys, underwater navigation transceiver, data control center, sea surface radio communication link and underwater acoustic communication link, when the underwater target requires positioning, the underwater navigation transceiver sends GPS The buoy emits the underwater acoustic positioning signal, and the buoy transmits the underwater acoustic positioning signal, GPS signal and attitude calibration data to the data control center by radio, and processes them together with the differential signal to calculate the position of the underwater target and the launching time of the underwater acoustic positioning signal. The acoustic communication system transmits the position and time data to the underwater navigation transceiver for navigation or timing. It only has the GPS positioning function of underwater objects and cannot complete the detection task around the water surface.
