Description

Technical Field

[0001] The present invention relates to the field of measurement, and in particular to a device and method for underwater target recognition. Background Art

[0002] Underwater target positioning and recognition has always been one of the hot research topics in military and civilian fields. Due to the complexity of the underwater environment and the limitations of hydroacoustic equipment, target imaging is subject to strong noise interference and the posture is easily disturbed during imaging. In order to accurately determine the target position, the posture and position of imaging equipment such as towed fish must be accurately determined at the moment of imaging. The underwater recognition device conducts research on underwater target positioning and recognition problems. The idea is novel, innovative and rich in content. The project results will have important theoretical and practical significance for marine military, marine engineering, marine remote sensing and marine development.

[0003] In the actual working process, if relatively turbid water is encountered, the distance sensors commonly used in actual work will be affected to a certain extent, reducing the accuracy of identification and measurement. If a submersible robot is used for underwater identification and measurement, encountering waters with more aquatic plants will cause the effect of identification and measurement to be greatly reduced. If only sonar mapping is used from top to bottom on the water body, although the height difference of the target can be detected and identified, if there is space under the detected target or a cavity inside, the existing technology is not convenient for detecting the cavity and the space under the object, especially in harsh environments, and it is not convenient to observe underwater measurement and identification. Summary of the invention

[0022] A device and method for underwater target recognition, comprising the following steps:

[0023] S1: First, place the main body of the device on the water surface and float it on the water surface. Connect the column to the staff's hull through a tripod, rotate the cross handle, and the cross handle drives the first winding roller to rotate. At the same time, the first gear plate and the first winding roller have the same rotation direction. At this time, the bevel gears at both ends of the rotating shaft revolve. Under the meshing action, the second gear plate rotates in the opposite direction of the first gear plate. The sizes of the first gear plate and the second gear plate are set to different diameters, and the rotation speeds of the two are different. Then, one end of the first rope is retracted and released faster and the other end is retracted and released slower, which is reflected in the hoisting roller being stably lowered.

[0024] S2: The first measuring rod, the second measuring rod and the third measuring rod are put on the object to be measured, and a servo motor with a waterproof effect is set. The output end of the servo motor pushes the first gear away, and the first tooth plate drives the movable bar downward, driving the vertical tooth plate to move downward. Under the meshing action of the gear tooth plate, the second gear and the third gear rotate in the opposite direction, and the second gear and the third gear drive the third tooth plate to move, so that the first measuring rod and the second measuring rod are driven to approach each other. At this time, the third measuring rod pulls the movable bar, and the movable bar pulls the second rope, and the second rope drives the third winding roller to rotate, so that the reading of the second dial can be recorded. The first measuring rod, the second measuring rod and the third measuring rod can wrap the object to be identified and measured in three directions. Combined with the sound identifier, when the mechanism is lowered to the water body and is about to start measuring, the clamping heads of the three measuring rods are first touched together, and the measurement and identification mechanism is placed at the lowest point to record the initial reading of the second dial.

[0025] S3: After the first measuring rod, the second measuring rod and the third measuring rod clamp the measured tube, record the reading of the second dial again, take the measuring identification mechanism ashore, set the three measuring heads again until the second dial displays the second reading again, bring the device up, lay the device horizontally, pull the measuring identification mechanism, and restore the underwater measurement scene on shore, and restore the measurement status of the three measuring rods.

[0026] The present invention provides a device and method for underwater target identification, and its beneficial effects include:

[0027] 1. By setting up a measurement and recognition mechanism, the three measuring rods of the mechanism can wrap the object to be identified and measured in three directions. Combined with the sound identifier, when the mechanism is lowered to the water body and is about to start measuring, the clamping heads of the three measuring rods are first touched together, and the measurement and recognition mechanism is placed at the lowest point, and the initial reading of the second dial is recorded. Then, after the three measuring rods clamp the pipe groove to be measured, the reading of the second dial is recorded again. After the measurement and recognition mechanism is taken ashore, the three measuring heads are set again until the second dial displays the second reading again. The underwater measurement scene can be restored on shore, which is convenient for intuitively identifying and measuring the parameters of the object to be measured. In the case of relatively harsh water bodies, the state of the three measuring rods clamping the object to be measured can be restored on the water surface to achieve a more intuitive measurement and recognition effect.

[0028] 2. By setting up a hoisting identification mechanism, the first rope can stably hoist the first installation frame of the mechanism in two directions during measurement, thereby improving stability. The two ropes can fix the heavy object from different angles to prevent the heavy object from shaking or rotating significantly during the hoisting process, thereby reducing the risk of accidents. Secondly, it enhances balance. The weight of the heavy object can be distributed more evenly, making the hoisting force more reasonable, thus avoiding rope breakage or hoisting device damage due to uneven force.

[0029] 3. By setting the first dial, when the measuring and identifying mechanism cylinder contacts the water body, the first dial is observed and the first reading is recorded. After the measuring and identifying mechanism touches the bottom, the sound identifier sends a signal displayed on the display screen, and the second reading can be recorded. The difference between the two readings is the depth of the water body, so that the depth of the water body at that location can be measured while the device is identifying underwater objects, eliminating the need to use ropes to lift heavy objects for measurement, which improves the measurement and identification effect to a certain extent. There are two vertical tooth plates. Combined with the first gear, the three measuring heads on both sides of the first mounting frame can move to different sizes, which is convenient for measuring objects with different diameters in one operation, thereby improving the diverse use of the device.
