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
Along with the fast development of China's economic construction, widen to solid space more city space, the building that build various places can be found everywhere, common are at present the industrial buildings such as the public gathering buildings such as large-scale exhibition center, gymnasium, megastore, passenger traffic hall and large-sized workshop, warehouse, oil depot, they often have various types of inner large spaces.The ceiling of this class 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.Although this class building has the advantages such as imposing, floor space is little, built-in function is numerous, but its internal staff is intensive, facility is complicated, often lay again a large amount of electric wires and high-power electric appliance, disaster hidden-trouble is numerous, especially when fire occurs, personnel are difficult for evacuating, and indoor air convection speed is fast, and fire spreading is rapid, burning is fierce, Hong combustion easily occurs, and giving puts out a fire to save life and property brings very large difficulty.
In recent years, the fire hazard monitoring problem of national large space building became increasingly conspicuous, and the wildfire accident of large space frequently occurs, and casualties and property loss are very serious.As on December 25th, 2000, there is wildfire in Dongdu Commercial Building, Luoyang City, causes 309 people's death, more than 70 people injured.On November 3rd, 2003, Hengyang, Hunan Province city Heng Zhou mansion generation wildfire, causes 20 fire fighters to sacrifice, and 11 fire fighters are injured.In this accident, the injures and deaths of firefighters have been once the most heavy since founding of New.On February 15th, 2004, Jilin ZhongBai Mall Rat generation wildfire, causes 54 people's death, more than 70 people injured, more than 400 ten thousand yuan of direct economic losses.So can the fire hazard monitoring problem of large space building obtain effectively solving 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, design and develop the automatic fire alarm and the fire extinguishing system that are adapted at using in large space building very urgent.
The fire hazard monitoring problem of large space building is always one of difficult problem that Fire Science researcher pays close attention in the world.In traditional fire alarm system, generally adopt water spray system to put out a fire, it is generally arranged in ceiling, and has the grid of special fire extinguishing to be connected with it.But water spray system can not meet the design for fire protection requirement of large space building.Main cause has following three:
(1) the pipe network complexity of water spray system, can affect the aesthetic property of whole building.
(2) water spray system wording depth is limited, if there is extensive fire, its water spraying falls from eminence, does not often arrive burning surface.
(3) spray equipment can not be realized and fix a point to put out a fire to save life and property, and sprays water comprehensively, thereby caused unnecessary water damage while putting out a fire to save life and property to protection zone.
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 countries at present, and research is thought: adopting with the automatic fire fighting cannon of flame detector interlock is the better scheme addressing this problem.Form detection and prevent and treat system with the fixed point active fire combining of putting out a fire to save life and property, realized in large space the unification of putting out a fire that links of automatic fire alarm and space orientation.Employing has automatic station-keeping system flame detector and controls fire-fighting battery, and realizing the active fire extinguishing system of fixing a point to put out a fire to save life and property is the effective scheme addressing this problem.With respect to water spray system, automatic fire fighting cannon 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, stronger to the penetration power in the scene of a fire, is difficult for atomization.
(3) pointing fire-extinguishing system water amount is few, and only, to conflagration area water spray, fire-fighting efficiency is high, and it is minimum that the loss that non-conflagration area is caused can reduce to.
(4) other automatic positioning fire extinguishing system has the function of Centralized Monitoring, can notify alarm of fire at once, takes measures rapidly, can further expand by Accident prevention, 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., smoke detection system occupancy volume is the highest, about 70-80%.But along with reaching its maturity of machine vision technique, adopt infrared CCD camera as sensor, utilize the image information of its collection to carry out detection location and there is larger feasibility, and have its unique superiority.Infrared CCD camera information amount is abundant directly perceived, can effectively reflect the feature of flame, and technology maturation, application popularization, type model is complete, cheap, and volume is little, lightweight, monitor area area is large, and the response time is short, can improve the stability of system and reduce system cost.Therefore, develop a kind of automatic positioning fire extinguishing system and become this area technical problem urgently to be resolved hurrily at present.
