Description
Technical field
The present invention relates to structural fire protection Internet of Things field, more particularly to a kind of interior based on intelligent evacuation indicating lamp is determined
Position system.The building of system is indicated suitable for fire-fighting evacuation must be installed, for personnel positioning in building in fire rescue and
Evacuation.
Background technology
Currently, China is in the high-speed developing period of economic society, all kinds of factors causing disaster showed increaseds, disaster scale
Constantly expand, especially the crowded place such as high level, high-rise building, once occurring fire, reached in extraneous rescue strength
Before, escape route is specified, extra exit is quickly found, it is the key point for avoiding tragedy from occurring that expansion escape in time, which is saved oneself,.
Intelligent evacuation indication system is distributing installation, the central controlled direction evacuated for personnel escape in building
Guidance system, trapped personnel can beacon light shows as indicated direction be quickly found out security against fire outlet；Meanwhile, system can be according to fire
Positioning of the calamity alarm control system to fire location, intelligence controls direction indication in real time, guides evacuating personnel, personnel are tight to batch
Anxious evacuation plays a role.
But intelligent evacuation indication system is in actual use, some problems are still suffered from.
1. trapped personnel can only be allowed freely to evacuate, when visibility is very low, it is impossible to see or the direction indication that offers a clear explanation, cause
Evacuating system fails.
2. during a large amount of evacuating personnels, the injures and deaths event such as trample easily is produced, outside control lacks actual personnel's distribution feelings
Condition makes reference, and shunting commander's effect is undesirable.
3. evacuation indication system is effective for the people with escape ability, but when falling in a swoon occur in personnel or lose escape
After ability, evacuation indication system is entirely ineffective.
Solve problem above, it is important to which positional information of the trapped personnel in building can be known in real time in Surveillance center.At present,
The technology that indoor occupant positioning can be realized is that the intensity and transmission time transmitted according to signal are positioned mostly, is had in theory
There is higher positioning precision, but in actual implementation process, due to blocking, reflecting, the such environmental effects such as temperature drift, often error
It is larger, while required complicated auxiliary facility also considerably increases the construction costs of system.
If increasing personnel positioning function by a kind of means on the basis of fire-fighting evacuation instruction system, making to be stranded
Personnel according to exit signs while escaping, and the positional information of all personnel can be known in real time in Surveillance center, according to these letters
Breath can make rationally control evacuation direction instruction, realize flow-dividing control.Meanwhile, it can also in real time position and lose the stranded of escape ability
Personnel, and deploy accurate rescue to it；To the place of densely populated place, rescue strength can be quickly reinforced；Fire-fighting to entering scene
Member can also position in real time.The extension of these functions will further improve the practical function that fire-fighting evacuation indicates system, also will be to go out
Fiery rescue action provides important decision-making foundation.
The content of the invention
It is a primary object of the present invention to provide a kind of intelligent evacuation system with RFID personnel positioning functions.And provide
Localization method and dispersal plan.Positional information of the Surveillance center to trapped personnel in building during escape is solved emphatically
Know in real time, and exit signs node display direction is controlled according to informixs such as personnel positions, fire locations, and then in personnel
Intensive place realizes that personnel re-assignment is evacuated, while being provided decision support for rescue action.

Order, according to nearby principle, modification positioning exit signs node direction indication, according to the order by hazardous area to place of safety to node
Incrementally numbered, point out escape route, the direction that guiding escape personnel increases according to numbering is advanced, and is quickly found out outlet；
(3) monitoring display terminal, the data message of real-time reception escape RFID tag, and the display mark in real time on the monitoring location drawing
The change in location situation of label, determines the approximate location of label；
(4) system acquisition trapped personnel positional information, according to the trapped personnel positional information known, calculates each passway for escaping
Density of stream of people, in the higher region of density of stream of people, point out an other passway for escaping, carry out shunting evacuation；And dispose fire-fighting
Strength enters the region of densely populated place, is effectively evacuated；
(5) according to live dangerous source position and dense smoke flow tendency, each region danger classes is adjusted in real time, is regenerated accordingly
Escape route, and change the danger classes instruction, escape direction instruction and numbering of each exit signs node.
