Problems solved by technology

[0004] The vibration and self-noise monitoring equipment applied to underwater unmanned submersibles is different from the conventional equipment used on other manned submersibles. If the data recording equipment is installed in the instrument cabin of the submersible, it is not convenient for direct manual operation and intervention. It is also not convenient to observe the measured data in real time; and the installation space inside the unmanned submersible is limited, and the volume and weight of the data recording equipment are limited accordingly, making it inconvenient to upgrade the system and expand the storage capacity

Abstract

The invention discloses a vibration and self noise monitoring system of a fuel-powered unmanned submersible vehicle. The system is mainly composed of a hydrophone, a triaxial accelerometer, a signal conditioning board, a power module, a communication antenna, a wireless communication module, multichannel data acquisition and recording equipment, a hydrophone adaptive mounting seat, a cabin penetration cable and the like. Signals sensed and received by the hydrophone and the accelerometer are transmitted to the signal conditioning board through the cabin penetration cable, are inputted to the wireless communication module after processed and are sent to the multichannel data acquisition and recording equipment by transmission of the wireless communication module. By the aid of the system, vibration and self noise of the unmanned submersible vehicle during underwater navigation can be monitored and recorded in real time.

Description

technical field [0001] The invention relates to a system for monitoring the working state of an underwater unmanned submersible, in particular to a vibration and self-noise monitoring system for a fuel-powered unmanned submersible. Background technique [0002] Fuel-powered unmanned submersibles are an important development direction of underwater vehicles. When they work, they are similar to conventional submarines under snorkel navigation. Since underwater unmanned submersibles in some special application fields have corresponding requirements for their own stealth performance, and the interference caused by their own radiation noise to the acoustic equipment on board must be considered, this requires the unmanned submersible underwater The vibration and self-noise of the submersible are recorded and monitored to provide reference materials for the overall structure design and optimization of the unmanned submersible. In addition, the damage of the propeller "cavitation" ...
