Automatic detection system of ship draught depth based on single-beam sonar array scanning technique

Abstract

The invention relates to an automatic detection system of a ship draught depth based on the single-beam sonar array scanning technique. The automatic detection system comprises a single-beam sonar primitive array, a sonar signal processor and a back stage master control system. The single-beam sonar primitive array is installed on an approach channel cross section so as to form a draught depth detection door device. The single-beam sonar primitive array is a combination of a set of single-beam transducers. The sonar signal processor is used for performing sequence collecting, signal amplifying, filtering, analog-digital conversion and DSP processing on all the transducers, and a formed digital signal is transmitted to the back stage master control system through the RS485 protocol. The single-beam sonar primitive array is connected with the sonar signal processor arranged on the shore through a watertight cable. The back stage master control system comprises a master control computer and a power supply unit. An upper computer software system is operated on the master control computer. The automatic detection system of the ship draught depth based on the single-beam sonar array scanning technique has the advantages of being small in investment, easy to install and maintain, simple, fast and efficient in measuring process and high in measuring precision.

Description

technical field [0001] The invention relates to an automatic detection system for ship draft depth based on single-beam sonar array scanning technology. Background technique [0002] Ship "overdraft", that is, the draft of the ship exceeds the maximum safe depth allowed by the lock. "Overdraft" is the most common and direct safety threat faced in the operation of ship locks. In light cases, it may cause ships to run aground and block navigation, and in severe cases, it may cause damage to ship locks and pose a serious threat to the safety of dam construction. During the navigation management process of hydropower stations, such behaviors often lead to grounding accidents at the gates of ships crossing the dam, which poses a greater threat to the safety of crew members, waterways and dam buildings, causes disputes, and affects the normal navigation dispatching work. [0003] This project is aimed at the above-mentioned problems, and the applicant of the present invention car...

"Overdraft" is the most common and direct safety threat faced in the operation of ship locks at present. In light cases, it may cause ships to run aground and block navigation, and in severe cases, it may cause damage to ship locks and pose a serious safety threat to dam construction

In the process of navigation management of hydropower stations, such behaviors often encounter accidents of stranded ships at the gate of the dam, which pose a greater threat to the safety of the crew, channel and dam building, cause disputes, and affect the development of normal navigation dispatching work
