Abnormal abrasion monitoring system and method for boat motive power system

Abstract

The invention discloses an abnormal abrasion monitoring system and an abnormal abrasion monitoring method for a boat motive power system. The system comprises a sensor group and an industrial control computer, wherein the sensor group is used for collecting abrasive particle image data, viscosity data and moisture data of oil liquid according to monitoring parameters set by the industrial control computer and sends the data to the industrial control computer, the industrial control computer is connected with the sensor group and is used for setting the monitoring parameters and storing received data. Through the on-line monitoring of abrasive particles, viscosity and moisture indexes of lubricating oil of boat motive power equipment, the on-line monitoring of the abnormal abrasion of a boat motive power system is realized, the fast response can be made on the abnormal equipment abrasion caused by reasons of lubricating effect reduction and the like because of the emulsification caused by the lubricating oil moisture pollution, and the defects that the sample period of the off-line oil liquid monitoring technology is long, the sampling process is complicated, and the oil sample representativeness is poor are avoided. The method belongs to an effective monitoring method for equipment abrasion conditions and abrasion abnormity of the boat motive power system, and the monitoring method can be used for the state discrimination, the fault diagnosis and the remaining service life predication.

Description

technical field [0001] The invention relates to the field of ship power system monitoring, in particular to a system and method for monitoring abnormal wear of a ship power system. Background technique [0002] Ship power equipment works in harsh environments such as high temperature, high humidity, high salt, and strong vibration for a long time. Once the engine and transmission device, which are the core of the ship power system, fail, it will seriously endanger the safety of the equipment and personnel in the ship, causing huge economic losses. loss. Therefore, timely and effective equipment condition monitoring for engines and transmissions can provide a basis for their maintenance and management work and ensure safe and stable operation of equipment. [0003] Oil monitoring technology has become the most widely used and effective technical means for state monitoring of ship power systems. The traditional off-line oil monitoring technology collects engine lubricating oi...
