Description

Technical Field

[0001] This invention relates to the field of underwater sonar detection, identification, and measurement, specifically a nine-square grid-type underwater acoustic marker. Background Technology

[0002] Sonar is a technology that uses the propagation and reflection characteristics of sound waves in water to navigate and measure distances through electroacoustic conversion and information processing. It also refers to electronic devices that use this technology to detect (existence, location, properties, direction of movement, etc.) and communicate with underwater targets. It is the most widely used and most important device in underwater acoustics. There are two types: active and passive. Sonar scanning and mapping can realize real-time monitoring of construction in underwater engineering, effectively improving the quality of underwater construction, and is widely used in underwater engineering.

[0003] A sonar device generally consists of three parts: an array, an electronic cabinet, and auxiliary equipment. The array is composed of underwater acoustic transducers arranged in a certain geometric pattern. Its shape is usually spherical, cylindrical, flat, or linear. There are receiving arrays, transmitting arrays, or combined transmitting and receiving arrays. The electronic cabinet generally has subsystems for transmitting, receiving, display, and control. Auxiliary equipment includes power supply equipment, connecting cables, underwater junction boxes, and amplifiers, as well as lifting, rotating, pitching, retraction, towing, hoisting, and deployment devices that are matched with the transmission and control of the sonar array, and sonar fairings, etc.

[0004] Passive sonar listening devices can quickly perform rough positioning by using the same signal received from different locations and processing it with a computer. This is more advantageous for submarines with larger hulls because the measurement baseline is longer and the accuracy is higher.

[0005] Sonar detection is greatly limited and affected by environmental conditions, the distance between the sonar equipment and the target, and the acoustic characteristics of the target. Furthermore, the markers used with sonar are easily interfered with by other noises in the water, which can easily lead to situations where ideal sonar images cannot be obtained or the specific location (coordinates) of the target corresponding to the feature points in the sonar image cannot be determined. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a nine-square grid-type underwater acoustic marker to solve the problems mentioned in the background. The present invention has a novel and simple structure, good recognition effect, and can reflect the target location information. It can effectively meet the requirements of underwater construction quality monitoring. Designed based on the acoustic scene of the detection target, it can effectively identify the location of the underwater detection target and measure it accurately, thereby greatly improving detection efficiency and construction accuracy.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a nine-square grid underwater acoustic marker, comprising a backing plate, wherein the backing plate is a square panel and is divided into 3×3 areas, and fixed frames of different arrangements can be installed on the surface of the backing plate, and markers are installed inside the fixed frames, wherein the markers are the same size as the fixed frames, and the fixed frames and marker panels are circular.

[0008] Furthermore, the top edge of the fixed frame is bent inward at 90°, and the sign can be wrapped inside the fixed frame by bending.

[0009] Furthermore, the outer ring of the fixed frame is symmetrically provided with four second screw holes, and the mounting position of the backing plate is provided with a first screw hole corresponding to the four second screw holes, and the first screw hole and the second screw hole can be fixed by bolts.

[0010] Furthermore, the arrangement scheme of the digital information of the identifier is divided into schemes of "0", "1", "2", "3", "4", "5", "6", "7", "8", and "9".

[0011] The beneficial effects of the present invention: The present invention provides a nine-square grid type underwater acoustic marker, including a backing plate; a first screw hole; a fixing frame; a second screw hole; and the marker.

[0012] 1. This nine-grid underwater acoustic marker can maintain good sound absorption performance and reduce interference from other noises by using polyurethane or rubber materials for the marker plate.

[0013] 2. This nine-grid underwater acoustic marker assembles the fixed frame and marker together through the first screw hole, the second screw hole, and bolts in different arrangements to form ten different digital information.

[0014] 3. This nine-grid underwater acoustic marker can be easily installed using the first and second screw holes, allowing for the creation of different patterns.
