With the increasing demand for water surveying, intelligent bathymetric unmanned vessels, with their advantages of high efficiency, flexibility, and low cost, are gradually replacing traditional manned survey vessels and are widely used in depth surveying
In modern information society, stable and high-speed network connections have become the infrastructure for production, daily life, and public services.
In the vast waters of rivers, lakes, and seas, intelligent unmanned boats undertake critical tasks such as water quality monitoring, hydrological mapping, security patrols, and even emergency search and rescue.
In modern network deployments, traditional wired connections are often costly, difficult to construct, or even impossible when crossing physical obstacles such as rivers, roads, hills, or historical buildings.
In the vast waters of rivers, lakes, and seas, accurate underwater topographic mapping has long relied on traditional manned survey vessels. This method is not only costly and risky, but also limited by human resources and environmental conditions.
The acoustic doppler flowmeter was developed to address this need. Instead of relying on mechanical rotation, it "listens" to the echoes of sound waves in the water flow, cleverly utilizing the Doppler effect to silently decode the secrets of water flow.
