Device for synchronously monitoring rotating speed/vibration of stern shaft of ship and application thereof

Abstract

The invention discloses a device for synchronously monitoring the rotating speed / vibration of a stern shaft of a ship and the application thereof; the device comprises a Hall sensor, a frequency counting module, a pulse shaping module, a trigger which is connected with the pulse shaping module, a three-axis vibration sensor which is connected with the trigger, a three-axis vibration sensor acquisition module and a main control module which are connected with the three-axis vibration sensor, and a signal output module and a communication module which are respectively connected with the main control module; the Hall sensor is respectively connected with the frequency counting module and the pulse shaping module; and the frequency counting module and the three-axis vibration sensor acquisition module are respectively connected with the main control module. The invention also provides the application of the device. According to the device for synchronously monitoring the rotating speed / vibration of a stern shaft of a ship and the application thereof, the correlation between the vibration and rotating speed of the stern shaft are fully considered, the device for synchronously monitoring the rotating speed / vibration of the stern shaft of the ship is ingeniously designed through the pulse output of the Hall sensor, so that richer data information is provided for monitoring the operation of the stern shaft of the ship.

Description

technical field [0001] The invention discloses a ship automatic monitoring device and an application thereof, in particular to a ship stern shaft rotational speed / vibration synchronous monitoring device and an application thereof. Background technique [0002] The vibration of the ship stern shaft and the speed of the stern shaft are important technical parameters reflecting the operating conditions of the ship stern shaft, and there is a strong correlation between them. The relationship curve between the two under normal working conditions and fault working conditions will show different characteristics, based on this characteristic, the failure analysis and early warning of the stern shaft of the ship can be realized. However, in the current ship stern shaft monitoring method, the information collection of stern shaft vibration monitoring and stern shaft speed monitoring is not synchronized, and the correlation between them is not considered. In the corresponding ala...

Problems solved by technology

However, in the current ship stern shaft monitoring method, the information collection of stern shaft vibration monitoring and stern shaft speed monitoring is not synchronized, and the correlation between them is not considered

In the corresponding alarm information, there are only abnormal stern shaft vibration alarms and high stern shaft speed alarms, and the above two alarms have no correlation
