Embodiment Construction

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

[0050] The state monitoring and fault monitoring and early warning system of the marine host 100 based on the theory of information entropy, including sensors, signal noise reduction processing equipment 110, data collector 120, discriminator 130, emergency executor 150, central processing unit 140; it is sensed by sensors The main state parameters of the ship main engine 100 are summarized to the data collector 120; the discriminator 130 determines the operating 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 calculates the information entropy weight for the transmitted data; synthesizes the comprehensive index of the operating state of the host 100 at each time ...

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 alarming technology, in particular to a system and method for monitoring the status of the main engine of a ship and monitoring and warning of failures. Background technique [0002] At present, the status monitoring of the ship main engine on various merchant ships generally adopts the form of data centralized display, and prints various alarm connected printers. In practice, the application of alarm printers is less. When the main engine parameters are abnormal and the monitoring of the main engine's operating status is abnormal, the line engineer is usually reminded to take emergency treatment in the form of sound and light alarm. This simple monitoring alarm system can intuitively reflect the fault status of a certain parameter of the equipment at the time, and does not have the ability to comprehensively analyze the operating status of the host. Engineers are required to determine the cause of the accident based...
