Device and method for measuring water draught of inland ship based on sonar synchronous scanning

Abstract

The invention discloses a device for measuring the waster draught of an inland ship based on sonar synchronous scanning. By using the device, the water draught of a ship is measured on line by adopting a sonar receiving device and a sonar transmitting device which move synchronously. The invention further discloses a measuring method based on the device. The device and the measuring method have the beneficial technical effects that sonar arrays are avoided being arranged in a high-density way through the scanning detection of a single set of the sonar transmitting device and the sonar receiving device; the equipment cost is decreased; synchronously, the requirements on the beam characteristics of sonar signals are decreased greatly; the problem that signals interfere mutually does not exist; the influence of a sonar divergence angle on detection precision is eliminated; and the detection precision can be improved to the utmost extent.

Description

technical field [0001] The invention relates to a ship draft depth measurement technology, in particular to an inland river ship draft depth measurement device and method based on sonar synchronous scanning. Background technique [0002] As the oldest transportation mode, water transportation has the outstanding advantages of large transportation volume, low investment, and low cost. In recent years, with the continuous advancement of the country's western development strategy and the vigorous implementation of many construction projects on the Yangtze River Golden Waterway and its tributaries, the advantages of inland waterway shipping have been continuously revealed, and water transportation capacity is showing rapid development. [0003] In order to ensure the smooth and unimpeded operation of inland waterways, it is necessary to conduct online measurement of ship drafts in certain river sections where ships are prone to stranding, so as to minimize the occurrence of ...
