Heave compensating control system of ocean exploration equipment and control method

Abstract

The invention relates to ocean exploration equipment, which belongs to the field of ocean exploration. A heave compensating control system of the ocean exploration equipment comprises exploration equipment, a lifting truck, a guide pulley and a compensating oil cylinder, wherein the lifting truck and the exploration equipment are connected by steel wires, and the guide pulley and the compensating oil cylinder are arranged between the exploration equipment and the lifting truck, the steel wires connecting the exploration equipment and the lifting truck lead out from the lifting truck and are wound on the guide pulley and connected with the exploration equipment after being wound on the compensating oil cylinder, a steel wire tension sensor is mounted on the guide pulley, the compensating oil cylinder is connected with an energy storage device, the steel wire tension sensor transmits signals to a heave compensating controller, the heave compensating controller is connected with the lifting truck and controls the lifting truck to adjust the exploration equipment. By combining the oil cylinder and tension compensation and combining active compensation and passive compensation, the heave compensating control system is applicable to various wave conditions, energy-saving and high in efficiency, can be closer to field conditions and high in control speed due to real-time feedback.

Description

technical field [0001] The invention relates to a marine survey equipment, in particular to a heave compensation control system of the marine survey equipment. Background technique [0002] The ocean contains a large number of resources, and the exploration, exploitation and utilization of resources are of great significance to the development of my country's ocean industry. Generally, when a survey ship equipped with marine survey equipment sets out to conduct survey activities at sea, the hull and survey equipment will produce longitudinal and lateral vibrations with the wave movement during the working process, so that The hoisting wire rope that hangs the survey equipment produces tension and bending deformation, thus affecting the reliability and stability of the marine survey system. In order to ensure the stability of the survey equipment operating in sea waves, it is necessary to increase the wave heave compensation control in the marine survey system. [0003] At ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a heave compensation control system and control method for marine survey equipment, to solve the problem that the heave compensation system of the current survey equipment has a relatively large lag, cannot achieve stable control, and partially consumes too much power. Large, the amount of information required and the amount of information processed are also large, and it is not suitable for small and medium power survey equipment and small survey occasions
