Description
Technical field
The invention belongs to exit signs technical field, more specifically to a kind of real-time automatic intelligence of emergency evacuation scheme
System can be generated.
Background technology
With expanding economy, the multi-functional building of complexity is more and more, especially the ultra-specification such as megastore
Building, when a fire evacuating personnel escape be particularly important.Increasing place starts with can be according to reality
The intelligent evacuation system that border situation changes exit signs direction automatically substitutes the Evacuation Indicatory Sign of single direction, so as to allow personnel
Quickly correctly evacuation escape.The building of selection intelligent evacuation have space big and complicated, passage and outlet are more can not one
The characteristics of mesh is clear, can usually make escape crowd vast and hazy in alarmed.Current each intelligent evacuation system is prior in prediction scheme mode
Establishment evacuation path, but the scale of construction is big because of place building, be possible to prediction scheme impossible to exhaust more than alarm point, typically all only considers single
One alarm point, can not more take the evacuation commander of Multiple Dots Alarm Rules or fire spread situation into account, allow the practicality of intelligent evacuation is big to give a discount
Button.
Exemplified by having the project of 100 independent alarm points, the evacuation prediction scheme of an alarm point is only considered simultaneously, must design
100 sets of plan, the engineer for having certain experiences can accomplish；The evacuation prediction scheme of any two alarm point is considered simultaneously, according to group
Hop algorithm, C (100,2)=4950 must design 4950 sets of plan, and the engineer team for having certain experiences perhaps can accomplish, but will
Spend the long period；The evacuation prediction scheme of any three alarm points is considered simultaneously, according to combinational algorithm, C (100,3)=161700, i.e. palpus
161700 sets of plan are designed, then experienced engineer team also is difficult to accomplish, even if they take long to.
The reference frame on the basis of actual alarm point of this program, calculates and generates live dispersal plan, effectively automatically in real time
The complicated problem of dispersal plan formulation impossible to exhaust under any Multiple Dots Alarm Rules situation such as fire spread has been cracked, has been had to intelligent evacuation
Important application value and social effect.
The content of the invention
It is an object of the invention to provide a kind of real-time automated intelligent generation system of emergency evacuation scheme, complicated fire can be reduced
Evacuation Design commander's difficulty at calamity scene, improves and ensures the possibility of all dispersal plans, prevent artificial prediction scheme amount it is big when people
The maloperation that may be brought for factor, it is ensured that the correctness in exit signs direction, makes intelligent evacuation more stablize safety.
The present invention can be achieved through the following technical solutions：
Alarm detector and indicating lamp for emergency are set to path node；
All through paths are initialized, routing database is formed；
According to keeping fire away, the principle of outlet evacuation nearby calculates and generates most short best-effort path；
The dispersal plan write into Databasce generated in real time calls for system and drives indicating lamp for emergency is oriented to light or close, simultaneously
The alert event and dispersal plan are preserved as daily record supplies ex-post analysis.
Beneficial effects of the present invention：
1）Realize multiple spot simultaneously or timesharing alarm when dispersal plan immediately automatically generate, improve under complicated fire hazard environment
System evacuates disposal ability；
2）Fire/smog spreading trend analysis and evacuation countermeasure are solved, fire development is improved and judges command ability；
3）The workload that system is installed, generates, tested is significantly reduced, operating efficiency is substantially increased.
Brief description of the drawings
Fig. 1 present system flow charts
Embodiment
The intelligent evacuation algorithm that the system is used is based on dijkstra's algorithm and finds most reasonable evacuation path.Dijkstra is calculated
Method is typical shortest path first, for calculating a node to the shortest path of other nodes.It is mainly characterized by with rise
(BFS thought) outwards is extended layer by layer centered on initial point, untill expanding to terminal.
Basic thought：
, it is necessary to specify starting point s (being calculated since the s of summit) when calculating the shortest path in G by Dijkstra.
In addition, introducing two set S and U.S effect be record obtained shortest path summit (and it is corresponding most
Short path length), and U is then to record the summit (and the summit to starting point s distance) for not obtaining shortest path also.
When initial, only starting point s in S；Being the summit in addition to s in U, and the path on summit is in U, " starting point s was to should
Summit path ".Then, the summit of shortest path is found out from U, and is added it in S；Then, update U in summit and
The path of vertex correspondence.Then, the summit of shortest path then from U is found out, and is added it in S；Then, update in U
Summit and the path of vertex correspondence.The operation is repeated, until having traveled through all summits.
Algorithm flow：
Alarm detector and indicating lamp for emergency are set to path node；
All through paths are initialized, routing database is formed；
According to keeping fire away, the principle of outlet evacuation nearby calculates and generates most short best-effort path；
The dispersal plan write into Databasce generated in real time calls for system and drives indicating lamp for emergency is oriented to light or close, simultaneously
The alert event and dispersal plan are saved in database as daily record and supply ex-post analysis.
Embodiment
(1) when initial, S only includes starting point s；Distances of the U comprising summit in other summits, and U in addition to s is " starting point s
To the distance on the summit ", for example, the distance of vertex v is the length of (s, v) in U, then s and v are non-conterminous, then v distance is
∞。
(2) " apart from most short summit k " is selected from U, and summit k is added in S；Meanwhile, summit is removed from U
k。
(3) distance of each summit to starting point s in U is updated.The distance on summit in U why is updated, is due to previous step
In k is determined is the summit for obtaining shortest path, so as to update the distance on other summits using k；For example, (s, v)
Distance is likely larger than (s, k)+(k, v) distance.
(4) repeat step (2) and (3), until having traveled through all summits.
