Embodiment Construction

[0049] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0050] The marine main engine 100 state monitoring and fault monitoring and early warning system based on information entropy theory includes sensors, signal noise reduction processing equipment 110, data collector 120, discriminator 130, emergency actuator 150, and central processing unit 140; The main state parameters of the main engine 100 of the ship, and summarize the parameters to the data collector 120; the discriminator 130 determines the running period of the main engine 100; after determining the operating period of the collected data, the data is transmitted to the main engine 100 fault detection processing unit and the display 141; the central processing unit 140 The fault detection processing unit of the computer calculates the information entropy weight for the transmitted data; synthesizes the comprehensive index of the operation state of t...

Abstract

The invention discloses an early warning system and an early warning method for state monitoring and fault monitoring of a marine main engine. The system comprises a sensor, signal noise reduction equipment, a data acquisition device, a central processing unit (CPU), a discriminator and an emergency actuator, wherein the signal noise reduction equipment is connected with the marine main engine and the data acquisition device; the data acquisition device is connected with the CPU through the discriminator; the CPU is connected with the emergency actuator; the emergency actuator is connected with the marine main engine and an acoustic-optical warning system; and the CPU comprises a fault detection processing unit and a display. Information entropy is taken as a weight determination tool of an equipment safety index, so that the objectivity of an index weight is reflected; a fault hidden danger index can be effectively determined, the system is timely maintained, and major accidents are prevented; and the index weight is determined by the information entropy, and an entropy weight is a dynamic weight, so the state of each index can be reflected in real time, and the index weight has timeliness.

Description

technical field [0001] The invention relates to monitoring and alarm technology, in particular to a system and method for state monitoring and fault monitoring and early warning of a ship main engine. Background technique [0002] Currently, the status monitoring of the ship hosts on various commercial ships generally adopts the form of centralized data display, and prints various alarms connected to printers. In practice, alarm printers are rarely used. When the parameters of the main engine are abnormal and the operating status of the main engine is abnormal, it usually reminds the liner crew to carry out emergency treatment in the form of sound and light alarm. This simple monitoring and alarm system can intuitively reflect the fault status of a certain parameter of the equipment at that time, but it does not have the ability to comprehensively analyze the operating status of the host. It is necessary for the engineer to determine the cause of the accident based on a com...
