Description

Technical field:

[0001] The present invention relates to sensing technology for marine measurement, in particular to measurement of deep sea pressure and flow velocity and direction of water flow, pressure and water depth measurement to eliminate the influence of water flow, acquisition of pressure information, flow velocity and direction information, and underwater robot or submersible movement. Sensor for potential speed information. Background technique:

[0002] Advanced underwater robots or submersibles are inseparable from sensors with reliable performance. Deep-sea pressure and flow velocity sensors are basic sensors that cannot be ignored by robots or submersibles when they go to the deep sea. The working principle of the current pressure sensor is difficult to meet the requirements of deep sea conditions. There is no domestic pressure sensor product that can be directly used in deep sea. Measuring the flow rate of seawater and the speed of underwater robots or subm...
