Problems solved by technology

However, the electromagnetic flowmeter has extremely high requirements on the external working environment, and the equipment needs strict maintenance. The space overhead required by the pipe-type electromagnetic flowmeter similar to the pitot tube is only larger than that of traditional sonar components.

Abstract

The invention belongs to the field of integrated circuit technology and electronic information, and particularly relates to a water flow monitoring system for an underwater vehicle. The main part of the monitoring system is a flowmeter chip array, and the flow velocity of a fluid on the surface of a chip is converted into a frequency signal. The system also comprises a neural network operation module behind the chip array, and achieves the recognition of the surrounding environment condition. The high power consumption of output signals and the high area overhead of a traditional flow meter are avoided by sensing the temperature through the flowmeter chip and outputting pulse signals with different frequencies. The distributed characteristic of the system can widely cover the surfaces of water and underwater vehicles such as ships and submarines, and the comprehensiveness of information collection is improved.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, and in particular relates to a water flow monitoring system for underwater vehicles. Background technique [0002] Since the invention of sonar in the last century, the nautical and marine industry has been able to modernize information detection technology. Using the propagation and reflection characteristics of sound waves in water, the technology of navigation and ranging through electro-acoustic conversion and information processing can also be used to measure the speed of the water environment. According to the comprehensive comparison of the water flow speed when the ship is stationary and the water flow speed in all directions of the ship when the ship is running, the navigation information such as the attitude of the ship can be determined. Sonar is the most widely used and most important device in underwater acoustics. [0003] However, the huge radio device affects the spa...
