Problems solved by technology

[0004] At present, in the face of the demand for ship "draft" data measurement, the corresponding detection methods at home and abroad are in the preliminary research stage, and there is no market-oriented and finished product system yet.
However, the measurement methods such as "manual observation" and "pressure sensing" adopted by most domestic shipping management units cannot meet the detection requirements of "disembarking, fast and automatic", and the measurement errors are large and the data reliability is low, resulting in Frequent aviation accidents have seriously affected the normal development of shipping dispatch

Abstract

The invention relates to an automatic ship draught detection system based on the multi-beam side-scan sonar technology. The automatic ship draught detection system comprises an underwater sonar scanning subsystem, a sonar signal processing subsystem and a master control subsystem. The underwater sonar scanning subsystem comprises a sonar transducer and a rotating motor, wherein the sonar transducer is provided with a 360-degree rotating shaft, and the rotating motor is used for driving the sonar transducer to rotate. The sonar signal processing subsystem comprises a watertight electronic cabin and a digital signal processing module located in the watertight electronic cabin, and data and command transmission between the sonar signal processing subsystem and the master control subsystem is carried out through a watertight cable. The rotating motor of the underwater sonar scanning subsystem is fixed in the watertight electronic cabin and connected with the digital signal processing module. The master control subsystem comprises a master control computer and a power supply unit, and display and control software of the automatic ship draught detection system operates on the master control computer. The automatic ship draught detection system has the advantages of being small in investment, easy to install and maintain and high in measuring accuracy, and the measurement process is convenient and fast to carry out and efficient.

Description

technical field [0001] The invention relates to an automatic detection system for ship draft depth based on multi-beam side-scanning sonar technology. Background technique [0002] The "overdraft" navigation of a ship mainly refers to the behavior of not taking load reduction measures when the draft exceeds the water depth of the channel for economic benefit. In the slightest, it will cause navigation obstruction, and in severe cases, it will cause serious accidents such as stranding of ships, damage to ship locks or ship lifts, and even personal casualties. [0003] Due to the low degree of standardization of the ship type of navigation ships and the large change of water level in the channel, it is very easy to produce "overdraft", which directly affects the safety of navigation. In recent years, this phenomenon has become the most serious and urgent problem threatening the safe operation of hydropower station navigation hubs. In order to ensure the safety and smooth flo...
