Description
Technical field
The present invention relates to the flame detection system of fire fire extinguishing system, particularly a kind of automatic location.
Background technology
Fast development along with the China's economic construction; Widen to solid space more the city space; The building that build various places can be found everywhere; At present common have industrial buildings such as public gathering building such as large-scale exhibition center, gymnasium, megastore, passenger traffic hall and large-sized workshop, warehouse, oil depot, and they often have various types of inner large spaces.The ceiling of this type large space building often can be up to 20-60 rice, and inside diameter can reach rice up to a hundred, can hold people up to ten thousand.Though this type building has advantages such as imposing, that floor space is little, built-in function is numerous, its internal staff is intensive, facility is complicated, often lays a large amount of electric wires and high-power electric appliance again; Disaster hidden-trouble is numerous; Personnel were difficult for evacuating when especially fire took place, and indoor air convection speed is fast, and fire spreading is rapid, burning is fierce; Hong combustion takes place easily, and giving puts out a fire to save life and property brings very big difficulty.
In recent years, the fire hazard monitoring problem of national large space building became increasingly conspicuous, and the wildfire accident in large space place frequently takes place, and casualties and property loss are very serious.Like on December 25th, 2000, wildfire took place in the Dongdu Commercial Building, Luoyang City, caused that 309 people are dead, the people is injured surplus in the of 70.On November 3rd, 2003, weighing apparatus state mansion generation wildfire in Hengyang City, Hunan causes 20 fire fighters to sacrifice, and 11 fire fighters are injured.In this accident the injures and deaths of firefighters be since the founding of New the most heavy once.On February 15th, 2004, ZhongBai Mall Rat generation wildfire in Jilin causes that 54 people are dead, the people is injured surplus in the of 70, more than 400 ten thousand yuan of direct economic losses.So can the fire hazard monitoring problem of large space building effectively be solved is the significant problem that is related to broad masses of the people's security of the lives and property.Therefore, improve the fire hazard monitoring facility of large space building, it is very urgent to design and develop the automatic fire alarm and the fire extinguishing system that are adapted at using in the large space building.
The fire hazard monitoring problem of large space building always is one of difficult problem of Fire Science researcher concern in the world.In traditional fire alarm system, generally adopt water spray system to put out a fire, it generally is arranged in ceiling, and has the grid of special-purpose fire extinguishing to link to each other with it.But water spray system has satisfied not the design for fire protection requirement of large space building.Main cause has following three:
(1) pipe network of water spray system is complicated, can influence the aesthetic property of whole building.
(2) the water spray system wording depth is limited, if extensive fire takes place, its water that sprays falls from eminence, has often arrived not burning surface.
(3) spray equipment can not be realized fixing a point to put out a fire to save life and property, and sprays water to the protection zone when putting out a fire to save life and property comprehensively, thereby has caused unnecessary water damage.
Based on this, research is proved to the fire extinguishing system in the large space buildings such as show room, gymnasium, warehouse by a lot of at present countries, and research is thought: employing is the better scheme that addresses this problem with the automatic fire control big gun of flame detector interlock.Form detection and the fixed point active fire that combines of putting out a fire to save life and property and prevent and treat system, realized the unification that automatic fire alarm and space orientation link and put out a fire in the large space.Employing has the automatic station-keeping system flame detector and controls fire-fighting battery, realizes that the active fire extinguishing system that fixed point is puted out a fire to save life and property is the effective scheme that addresses this problem.With respect to water spray system, automatic fire control big gun fire extinguishing system can overcome the shortcoming of water spray system.
(1) its installation is hidden, and pipeline is simple.
(2) current are concentrated, and water discharge density is high, and is stronger to the penetration power in the scene of a fire, are difficult for atomizing.
(3) pointing fire-extinguishing system water amount is few, and only to the conflagration area water spray, fire-fighting efficiency is high, can reduce to minimum to the loss that non-conflagration area caused.
(4) in addition automatic positioning fire-extinguishing system has the function of Centralized Monitoring, can notify alarm of fire at once, takes measures rapidly, and the accident that can prevent further enlarges, and the loss that fire is caused drops to minimum degree.
Numerous fire detecting systems of scientific research institution and the exploitation of each major company are based on various fire recognition modes both at home and abroad; Commonly smoke detection system, heat-detection system, flame detection system, gas detection system and combined type detection system etc.; The smoke detection system occupancy volume is the highest, about 70-80%.But along with reaching its maturity of machine vision technique, adopt the infrared CCD camera, utilize the image information of its collection to carry out the detection location and had bigger feasibility, and its unique advantages is arranged as sensor.Infrared CCD camera information content is abundant directly perceived, can effectively reflect the characteristic of flame, and technology maturation, application popularization; The type model is complete, and is cheap, and volume is little, in light weight; The monitor area area is big, and the response time is short, can improve the stability and reduction system cost of system.Therefore, develop a kind of automatic positioning fire-extinguishing system and become the technical problem that this area needs to be resolved hurrily at present.
