Portable multi-beam depth sounder

Abstract

The invention relates to portable type multi-beam depth sounder. It includes above water control processing extension, receive-dispatch combining transducer array, receive-dispatch switching circuit. The above water control processing extension is made up of industrial personal computer, programmable signal source, signal emitting, adjusting, collecting, and processing systems, display, and mass storage. The invention uses multi channel transducer array and pre-forming multi wave packet technique to gain multipoint depth water data for once measure to increase measuring accuracy and working efficiency. And the transducer is hung at the side of the ship which is portable and convenient for installing. Thus the invention can be widely used in underwater topographic survey for shallow sea and inland lake and river, ocean engineering, reservoir survey etc.

Description

(1) Technical field [0001] The invention relates to the field of detection, in particular to a multi-beam sounder. (2) Background technology [0002] With the continuous development of science and technology, the space for human activities has basically reached every corner of the world. Since more than 70% of the earth's area is covered by water bodies, including oceans, rivers, lakes, and reservoirs, many scientific and engineering fields involve the measurement of underwater topography, such as underwater construction, port construction, channel survey, etc. . [0003] Foreign countries have started to develop underwater terrain detection equipment since the middle of the last century. After decades of development and change, from the initial single-beam sounder to the later multi-beam sounder, a series of products have been formed to meet different needs of users. In China, the information, patents and products about underwater terrain detection equipment that can be ...

AI Technical Summary

Problems solved by technology

[0006] Since the research and development of underwater terrain measurement technology and equipment in my country lags far behind western countries, the multi-beam measurement equipment currently applicable in China is mainly underwater terrain detection equipment imported from abroad. However, these equipment are expensive and difficult to install and install. There are many inconveniences in use and maintenance, and various objective facts clearly show that my country has a strong demand for low-cost underwater terrain detection equipment that is easy to install and use.
