Method and device for assessing level of fire interlock alarming in ship cabin

Abstract

The invention provides a method and a device for assessing levels of fire interlock alarming in a ship cabin. The method comprises the following steps that: 1) a central fire alarm control unit acquires fire situation information obtained by temperature sensing detectors and smoke sensing detectors which are in all ship cabins and adjacent to the ship cabin in which fire breaks out; 2) the central fire alarm control unit reads danger level information of the fire in the ship cabin; 3) the fire situation information obtained by the temperature sensing detectors and the smoke sensing detectors and the danger level information of the fire in the ship cabin are subjected to normalized pre-processing; and 4) processed data are sent to a fuzzy reasoning module to be subjected to fuzzy reasoning, so that a level assessment result of the fire interlock alarming in the ship cabin is obtained. On the basis of no increase of additional detection equipment and no addition of cost, information data from different types of detectors in all the ship cabins and danger level information data of the fire are analyzed and processed by using a fuzzy reasoning system; the alarming level information in each ship cabin is rapidly and correctly given, the correctness, the leading and the comprehensiveness of the interlock alarming of the ship cabin can be realized as far as possible, and serious fire accidents caused by omission of the fire situation information of the ship cabin are reduced.

Description

technical field [0001] The present invention relates to an automatic fire alarm method, in particular to an intelligent fire alarm method, in particular to a fuzzy control-based fire chain alarm level evaluation method and device for ship cabins. Background technique [0002] With the development of science and technology, countries around the world are vigorously developing the maritime industry. As an important tool for maritime transportation, ships have become the focus of attention. Due to the complex environment of modern ships, the cabin space on board is small, the mechanical equipment is tightly placed, the gas and liquid transportation and circuit lines are complicated, so when a fire occurs in a cabin in a certain area, the adjacent cabins will inevitably be implicated. If the fire is not discovered in time , as the fire intensifies, it will spread to several cabins through walls or interconnected ventilation pipes, oil and gas transportation pipes, cables, etc., ...

Problems solved by technology

However, today's intelligent fire alarm system only focuses on the accurate judgment of the detector on the fire situation, reduces the frequency of false alarms and omissions, improves the system response sensitivity, and starts the fire extinguishing facilities quickly, etc., while ignoring the fire alarm system. The importance of "mainly" and supplemented by "elimination"
