Description

Assessment of building fire situation and evacuating personnel indication mechanism
Technical field
The utility model relates to structural fire protection monitoring technique field, particularly a kind of building fire situation assessment and evacuating personnel indication mechanism.
Background technology
In the middle of current building, especially have in the middle of the heavy construction of labyrinth, the security against fire evacuating system is absolutely necessary, so that when fire takes place, can the guiding crowd evacuate, and reduces casualties.Traditional security against fire evacuating system is formed by being installed in evacuation indication static state on the passage, that point to the extra exit, and there is numerous drawbacks in this fire-fighting evacuation system, demands improvement urgently:
The first, traditional fire-fighting evacuation system is static system, can not change with the state of disaster development, thereby personnel might be guided to the deathtrap.As in the fire development process, some is evacuated on the path and is blocked and can not pass through by fire, only relies on static evacuation indication then personnel may be guided to this deathtrap.The applying date is 2007-06-19, publication number is the utility model patent " a kind of fire alarm control system " of CN101079178A, attempt to utilize the alarm signal of fire alarm system that dispersal plan is adjusted dynamically, and in the middle of this utility model, only used the finite information of fire early period of origination fire alarm position, the overall process that fire is taken place does not monitor effectively, predicts and assess that its dispersal plan that provides is along with the development of fire disaster may be no longer suitable.
The second, in traditional security against fire evacuating system, can not effectively consider personnel's the influence of jam situation, thereby may cause blocking up of regional area, reduce the efficient of evacuating evacuating.In the middle of the existing building, fire-fighting system and safety-protection system are separate systems, and fire-fighting system is responsible for disasters such as fire are monitored, and safety-protection system comprises that video monitoring, gate control system etc. are responsible for personnel are monitored.Owing to lack personnel positions monitoring system and the integrated method of evacuating system, make fire-fighting safety system can not consider the influence to evacuation such as density of personnel real-time distribution in the evacuation process, can only tightly depend on the disaster monitoring information that fire-fighting system provides.The applying date is 2005-09-15, and publication number is the utility model patent " system such as intelligent evacuation indication " of CN1783154A; The applying date is 2006-02-1, and publication number is the utility model patent " evacuating system that comprises rescue guide lights " of CN101119771A; These utility models attempt to link to each other with fire alarm system by some the dynamic indication hardware of evacuating, thereby provide dynamic evacuation direction, and in these systems, do not consider that personnel positions and density of personnel are to evacuating the influence of efficient.
Three, in the traditional security against fire evacuating system, lack the effective ways of the monitoring of effective integration fire sensor and personnel's monitoring system, can not effectively provide the dispersal plan of optimization in real time according to monitoring information.The applying date is 2001-10-15, and publication number is the utility model patent " intelligent fire prompting and command evacuating system for public place " of CN1412723A, attempts to utilize expert system, according to the positional information of fire alarm, provides corresponding dispersal plan.Yet employed expert system depends on static relatively expertise, and its input only is limited incipient fire annunciator message, be not enough to dispersal plan is revised in the fire development process of dynamic change, the dynamic change emergency is successfully managed.
Four, in the middle of the architectural environment of complexity, traditional fire-fighting system lack to the evacuation personnel monolithic architecture structure, fire development situation are provided, the effective means of the information such as evacuation path that should select, make to evacuate to have bigger blindness.In traditional evacuating system, the evacuation personnel can only be provided the local messages such as evacuation direction that the present position should be taked, and shortage effective and efficient manner such as the building structure information of the vital integral body of evacuation decision-making, the whole fire development situation of building interior information are transmitted, thereby influence the efficiency of decision-making of evacuating greatly.
