Active wave compensating device and method applied to depth sounder

Abstract

The invention discloses an active wave compensating device and a method applied to a depth sounder. The active wave compensating device comprises a first compensating unit, a second compensating unitand a detecting unit, wherein the first compensating unit is provided with supporting assemblies, a transmission component and a power component; the second compensating unit is in transmission connection with the first compensating unit, and comprises a platform assembly, compensating assemblies, a supporting component and a connecting piece; and the detecting unit is connected with the supporting assemblies. According to the active wave compensating device disclosed by the invention, the movement parameters of the swinging and the heaving of a hull are measured by a micro-inertial sensor, and are converted into digital signals; the digital signals are transmitted to a control system for processing, and the compensation capacity of the swinging and the compensation capacity of heaving arecalculated out; and a servo motor and a servo electric cylinder are driven by the processed signals to move, so that the compensation of a compensation platform in the swinging direction and in the heaving direction is realized. Through the adoption of the active wave compensating device disclosed by the invention, the depth sounder which is influenced by the movements of swinging and heaving canbe accurately and quickly compensated, so that the depth sounder can safely and efficiently execute a detection task under a complicated marine condition; and the active wave compensating device hasthe characteristics of being wide in compensation range, high in reliability, accurate and quick, simple and light in structure, and the like.

Description

technical field [0001] The invention relates to the field of active compensation, in particular to an active wave compensation device and method applied to depth sounders. Background technique [0002] The water quality in the East my country Sea region, the Yangtze River Basin, and river estuaries in China is turbid and the line of sight is poor. When the general navigation equipment cannot work normally, the depth sounder can be used to achieve positioning and navigation, especially when the ship enters the shallow water channel. Other navigation equipment is irreplaceable, and it is more reliable to use the depth sounder to identify the position in some sea areas with special or regular changes in water depth. The modern multifunctional marine depth sounder can also realize the functions of underwater survey, fish detection and tracking, so the depth sounder is widely used in hydrographic survey, hydropower plant, reservoir area, shallow sea, lake, river channel survey, en...

Problems solved by technology

In active compensation equipment, the comprehensive effect of compensation using parallel stable platforms is better, but it is generally used on large ships, and requires a long hydraulic cylinder, which undoubtedly increases the cost and reduces the stability of the system

[0004] Although the above-mentioned stable platform can solve the problem of active compensation, the structure uses a large number of servo electric cylinders, resulting in complex redundancy, high cost and poor stability
