Underwater river landform measurement device and measurement method for large rivers

Abstract

The invention discloses an underwater river landform measurement device and a measurement method for large rivers. The device comprises a control base station and an exploitation ship, wherein a radarcollision-avoiding sonar is arranged in the front of the exploitation ship; a combined sonar, a communication antenna, a GPS (Global Positioning System) antenna and a sailing system are arranged on the exploitation ship; the combined sonar comprises a lateral scanning sonar and a multi-beam echo sounder; by using the combined sonar on the exploitation ship, landform information of the bottom of ariver is measured, obstacle information on a sailing line is acquired by using the radar collision-avoiding sonar, communication with the control bases station is realized through the communication antenna, real-time position signals are acquired through the GPS antenna, and the sailing speed and the sailing direction of the exploitation ship are controlled by the control station through the sailing system. The device is based on a multi-beam echo sounding technique, is applicable to river bottom landforms, is capable of exploring obstacles in a forwarding direction of the exploitation ship through the foresight collision-avoiding sonar in the front of the exploitation ship, ensuring the sailing security of the exploitation ship and greatly alleviating working intensity, and is high in measurement efficiency.

Description

technical field [0001] The invention relates to the technical field of channel surveying, in particular to an underwater channel topography measuring device and a measuring method for large rivers. Background technique [0002] my country's inland includes a large number of large rivers and rivers. In the process of inland river management, it is often necessary to draw topographic maps of the bottom of the river. In the past, the measurement method used manual measurement to measure the depth of the river. This method cannot be drawn well. Topography and landforms at the bottom of the channel. [0003] With the advancement of science and technology, various advanced equipment emerge in an endless stream, and equipment that can be used to measure water depth continues to be used. [0004] There are already many instruments and equipment to measure underwater topography. There are two main types: ocean bottom topography measurement, and underwater sonar detection based on the...
