An underwater vehicle water flow monitoring system

Abstract

The invention belongs to the field of integrated circuit technology and electronic information, in particular to a water flow monitoring system for an underwater vehicle. The main part of the monitoring system is a flowmeter chip array, which converts the fluid velocity on the surface of the chip into a frequency signal. It also includes a neural network computing module behind the chip array to realize the recognition of the surrounding environment. The high power consumption of the output signal and the high area overhead of the traditional flow meter are avoided by using the flow meter chip to sense the temperature and outputting pulse signals with different frequencies. Its distributed characteristics can be widely covered on the surface of underwater vehicles such as ships and submarines, improving the comprehensiveness of information collection.

Description

Technical field [0001] The present invention belongs to the technical field of underwater vehicles, specifically relates to underwater vehicle water flow monitoring system. Background [0002] Since the invention of sonar in the last century, the nautical and marine industries have been able to modernize information detection technology. The technology of navigation and ranging through electroacoustic conversion and information processing by using the propagation and reflection characteristics of sound waves in water can also be used to measure the speed of the water flow environment. According to the comprehensive comparison of the water velocity when the vessel is stationary and the speed of the water flow in all directions of the vessel when the vessel is running, navigation information such as the attitude of the vessel can be determined. Sonar is one of the most widely used and important devices in hydroacoustics. [0003] However, the huge radio device affects the space vol...

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.
