Ship damage management monitoring system based on PLC integrated fire alarm control

Abstract

The invention provides a ship damage management monitoring system based on PLC integrated fire alarm control. The ship damage management monitoring system comprises an upper computer, a PLC subsystem,a control display unit, a sensor, an actuator and a fire detection alarm control loop; the fire detection alarm control loop is a loop formed by connecting a fire detector, fire-fighting execution equipment and a manual alarm button through a fire-fighting second bus. With the system of the invention adopted, defects in the prior art can be eliminated. The invention provides a ship damage management monitoring method based on PLC integrated fire alarm control. According to the method of the invention, a fire detection alarm controller level in an existing system can be canceled, a monitoringlevel is simplified, operation stations are reduced, hardware cost of the damage management system is reduced, the hardware module of the system is enabled to meet standardization and reliability requirements, the maintenance performance of the system is improved, and the management operation of the system is enabled to be more real-time and effective.

Description

technical field [0001] The invention relates to the field of ship automation monitoring design, in particular to the design field of a ship damage control monitoring system based on PLC controllers, PLC distributed modules, manual alarm buttons, detectors and fire execution equipment.

AI Technical Summary

Problems solved by technology

This design increases the type, quantity, interface and monitoring level of equipment, which is not conducive to the integration and optimization of the system.

In addition, the fault diagnosis of the existing fire detection and alarm equipment needs to be connected to external equipment, which cannot adapt to the on-site status for real-time adjustment, fault diagnosis, detection and maintenance
