Remote-control romote-sensing automatic optronic detecting buoy

Abstract

Belonging to technical area of ship engineering, the buoy includes case, photo detector, signal processing encryptor, transmitting transducer array, rechargeable battery, instruction receptor, controller, solar panel set, LED and accumulator etc. The photo detector possesses two observation channels: ordinary light and infrared to accomplish observational mission at daytime and night. After the encryptor processes image signal obtained, transmitting transducer array sends hydroacoustic signal to underwater parent boat. Receiving energy from sun, solar panel set charges rechargeable battery. Light controlled switch controls irradiance of LED at night to play function of beacon. The instruction receptor composed of receiving transducer array and decryptor is in use for receiving on / off instruction sent from parent boat to carry out processes of decryption and amplification. Encrypted detection signal sent from buoy guarantees reliable transmission of information.

Description

technical field [0001] The invention relates to a buoy, in particular to a buoy with remote control, telemetry and automatic photoelectric detection which converts detected image signals into electrical signals and transmits them to underwater mother submersibles by means of underwater acoustic wireless communication, which belongs to the technical field of ship engineering Image information acquisition and transmission equipment category. Background technique [0002] Submersibles usually have to float to a depth of several meters below the surface of the water in order to use the periscope protruding from the water to detect the surrounding conditions on the sea surface. Floating and sinking navigation operations are complicated; Composed of a wire-wound fiberglass shell and a foldable antenna, with a horizontal rudder and a vertical rudder at the tail, it sails close to the water surface with the submersible.

[0002] Submersibles usually have to float to a depth of several meters below the surface of the water in order to use the periscope protruding from the water to detect the surrounding conditions on the sea surface. Floating and sinking navigation operations are complicated; Composed of a wire-wound fiberglass shell and a foldable antenna, with a horizontal rudder and a vertical rudder at the tail, it sails close to the water surface with the submersible. The buoy transmits the detected signal to the submersible through a cable. When the towed buoy is recovered, The operation is very difficult; the patent No. CN95120943.4 is the invention patent of "full non-magnetic glass fiber reinforced plastic composite material telemetry buoy carrier", which is composed of a telemetry buoy and a marker buoy. , this patent can be used for high-precision collection of magnetic characteristics in water areas, but it cannot complete the tasks of target detection and signal transmission to the seabed; the patent number is CN200420050637.3, a utility model patent for "a tide level buoy detector based on satellite positioning system", It is a utility model patent for "buoy-type photoelectric camera lookout platform" with application number 02275002.7, which can carry out long-distance ocean tide level monitoring and realize the transmission of long-distance measurement data. Place the photoelectric camera on the non-metallic streamlined buoy on the lookout platform, connect the platform and the camera on it with the submersible with a traction rope, power cord, video cable, and control cable, and the video signal is converted into a digital signal by the image acquisition card It is transmitted to the submersible through a cable. It is also a detector whose body must protrude from the water surface. When the submersible wants to use this patent, it still needs to be equipped with cable communication.
