Ship accumulator cabin ventilation and automatic extinguishing method and system based on fuzzy control

Abstract

The invention provides a ship accumulator cabin ventilation and automatic extinguishing method based on fuzzy control. The method comprises the steps that the environment temperature and the smoke density of a ship accumulator cabin are collected; a fuzzy control model is established; a collected signal is used as the input quantity of the fuzzy control model, and the input quantity is fuzzified according to a preset fuzzy set; the fuzzy control quantity is obtained through fuzzy reasoning according to a preset control rule list; the fuzzy control quantity is multiplied by a proportionality coefficient after being defuzzified to obtain the control quantity; the control quantity is output to an alarm device, an extinguishing device and a ventilation system; and whether the alarm device, the extinguishing device and the ventilation system are started or not is selected according to the control quantity. By adoption of the ship accumulator cabin ventilation and automatic extinguishing method, cabin ventilation and early warning can be achieved, it is ensured that a fire is prevented before occurring, or a fire is automatically extinguished after occurring, the fire behavior is weakened maximally, personnel are evacuated in advance, and casualties and property loss are reduced.

Description

technical field [0001] The invention belongs to the field of water traffic safety and fire protection, and in particular relates to a fuzzy control-based method and system for ventilation and automatic fire extinguishing of battery compartments of ships. Background technique [0002] In recent years, ship energy-saving and emission-reduction technologies have developed very rapidly, especially clean energy ships represented by solar energy, wind energy, and storage batteries are overwhelmed. At present, pure battery electric ships and hybrid ships that use various new clean energy sources as ship propulsion power sources all choose power battery packs as energy storage devices on board. [0003] Because today's battery and battery management technology is not mature enough, and the safety of the power battery pack itself is lower than that of the traditional diesel engine as the main engine of the ship, especially when the ship encounters sudden accidents such as collisions ...

AI Technical Summary

Problems solved by technology

[0004] The power battery packs of pure battery electric boats and hybrid boats are generally placed in the battery cabin, and the electrolyte gas may leak during the working process of the battery. Because of its flammability, it is easy to cause fire and explosion if it reaches a certain concentration; at the same time, the battery must 24 hours of uninterrupted work, if the working time is too long, it will generate a lot of heat, causing high temperature or even a fire
