Abstract

The invention discloses a machine-mounted dipping sonar winch with multiple retractable means and a control method thereof. The dipping sonar winch comprises a cable position angle sensor (1), a length measuring pulley (2), a cable length sensor (3), a cable rope (4), a winding drum (5), a cable arranging pulley (6), a cable arranging shaft (7), a lower limit sensor (8), a speed measuring generator (9), a brake (10), a proximity sensor (11), an emergency motor (12), a reduction gearbox (13), a hydraulic motor (14), a servo valve (15), a solenoid valve (16), an upper limit sensor (17), a cablebreaking device (18) and a control box (19). According to the invention, three hydraulic, electric and hand operation retractable means and two motor / pump hydraulic motor modes are provided; the control precision of the cable rope is enhanced via the length measuring pulley and the cable length sensor; and the retractable speed of the cable rope is controlled according to the stable / unstable worksituations of the winch by using the specialist system of embedded predictive control.

Description

technical field [0001] The invention relates to the technical category of an airborne hoisting and launching sonar winch, in particular to an embedded predictive control expert system and a hoisting and hoisting sonar winch that provides multiple retracting means. Background technique [0002] Shipborne helicopters equipped with dipping sonar are powerful anti-submarine weapons. Under the current technical conditions, anti-submarine helicopters have a clear advantage in the game between submarines and submarines. Dropping sonar has the advantages of small size, light weight, flexible maneuvering, fast response, can detect, identify and track multiple targets, and can be used repeatedly for a long time. "Finding the enemy first" is the primary condition for victory in information warfare. Since the installation platform for hoisting sonar is a ship-borne helicopter, the range of the helicopter is actually the distance of "finding the enemy first" of the anti-submarine helicop...
