A kind of gridding automatically generates the method evacuating prediction scheme

Technical field

The present invention relates to a kind of method automatically generating evacuation prediction scheme that can be used in intelligent fire emergency lighting and evacuation indication system, it is automatically searched outlet according to gridding fire escape thus generates evacuation prediction scheme, belongs to intelligent fire emergency lighting and evacuation indication system field.

Background technology

In general industry with civil buildings, install and use intelligent fire emergency lighting and evacuation indication system more and more, within the system, existence can tuning fire-fighting emergent identification lamp tool, be used to refer to evacuate direction, when building in breaking out of fire time, this fire-fighting emergent identification lamp has, the sensing of arrow can be adjusted such that it is able to provide correct evacuation direction for evacuee, avoid conflagration area by the evacuation prediction scheme pre-set.

In order to enable when fire occurs, start accurately and evacuate prediction scheme accordingly, intelligent fire emergency lighting and evacuation indication system to be worked out respectively for the fire detection equipment in building and to evacuate prediction scheme accordingly, in each evacuation prediction scheme, adjusts the sensing of fire-fighting emergent identification lamp tool.At present, the evacuation prediction scheme in intelligent fire emergency lighting and evacuation indication system needs personnel's hand weaving, the problem that so there is the aspects such as workload is big, repeated work, error rate are high, efficiency is low, affects cost of building projects, causes potential safety hazard.

Summary of the invention

It is an object of the invention to overcome personnel's hand weaving to evacuate the deficiency of prediction scheme, it is provided that a kind of more efficient, gridding more accurately automatically generates the method evacuating prediction scheme.

For realizing object above, the present invention is achieved through the following technical solutions:

A kind of gridding automatically generates the method evacuating prediction scheme, two stage etch of prediction scheme are evacuated with automatically generating including gridding definition fire-fighting area attribute, wherein, described gridding definition fire-fighting area attribute stage etch includes fire escape and the gridding of outlet and the incidence relation setting up grid and equipment, automatically generating and evacuating prediction scheme stage etch is the fire-fighting area attribute according to gridding definition, is that each fire detection equipment generates evacuation prediction scheme successively automatically.

The gridding definition fire-fighting area attribute stage has the following steps:

1, on fire-fighting region, drawing the polygonal mesh of auxiliary, whole grid is formed m*n independent polygonal element lattice by m line number and n columns, and the attribute of each cell can be the one in " forbidden ", " passage " and " outlet " three kinds of states；

2, by fire-fighting regional channel and exit position, corresponding is set to the respective cells in grid " forbidden ", " passage " or " outlet "；

3, drag to set up on " passage " cell accordingly interrelated by the control point that fire detection equipment and fire-fighting emergent identification lamp have, now these equipment and light fixture will be affected by this cell.

Automatically generate evacuation the prediction scheme stage have the following steps:

1, it is set to " forbidden " by evacuating the cell attribute that fire detection equipment corresponding to prediction scheme be associated；

2, it is followed successively by each " passage " cell by software algorithm and searches nearest " outlet " cell, and the sensing of this " passage " cell is set to the sensing to " outlet " cell；

3, the sensing being had by the fire-fighting emergent identification lamp associated by " passage " cell is adjusted with reference to the sensing of " passage " cell self, and adds fire-fighting emergent identification lamp tool to current evacuation in prediction scheme.

A kind of gridding automatically generates the method evacuating prediction scheme, it is characterised in that:

1, gridding fire escape and outlet, it is broken down into independent cell, adjacent cells lattice can mutually access, determine which cell search can evacuate path by by cell " forbidden ", " passage " and " outlet " attribute, search the shortest path of all outlet ports successively, then choosing the outlet of shortest path, as escape opening, this path is as evacuating tuning foundation；

2 、The control point that fire detection equipment and fire-fighting emergent identification lamp have is dragged to set up on cell association, between control point and equipment, passes through line and curve connection.The cell equipment associated with it interacts, when generating evacuation prediction scheme corresponding to fire detection equipment, represent breaking out of fire near this fire detection equipment, so the cell associated by this fire detection equipment will be designated " forbidden " state, do not allow to be exported by this cell search, and after a cell obtains exit signs, the fire-fighting emergent identification lamp tool that it is associated also will generate prediction scheme with reference to this exit signs.

The beneficial value of the invention:

1, use this technical method, automatically generate evacuation prediction scheme, improve work efficiency, reduce implementation cost；

2, by automatically generating evacuation prediction scheme, it is to avoid human intervention causes mistake, potential safety hazard is produced.
