Monitoring point or outlet.Use " all removing " function, it will remove rendered whole route maps.
In map interface, end points is black, and monitoring point is yellow, is exported as blueness, road is grey, does not draw any
Content regions are white.
Setting-out principle：
In the case where dx is more than or equal to dy, straight slope k=dy/dx is obtained by 2 points.The starting point of straight line is in the pixel
The heart, so error term d initial value d=0.X subscripts often increase the slope value k, i.e. d=d+k that 1, d value is accordingly incremented by straight line.One
It, is just subtracted 1 by denier d >=1, so ensures d between zero and one.As d >=0.5, picture element (x+1, y+1) is drawn, and works as d<
When 0.5, and drafting picture element (x+1, y).In the case where dy is more than dx, straight slope k=dx/dy is obtained by 2 points.Of straight line
The initial point heart in the pixel, so error term d initial value d=0.Y subscripts often increase the slope value k that 1, d value is accordingly incremented by straight line,
That is d=d+k.Once it, is just subtracted 1 by d >=1, so ensure d between zero and one.As d >=0.5, picture element (x+1, y are drawn
+ 1) d is worked as<When 0.5, picture element (x, y+1) is drawn.
Drawn path figure restriction rule：
1st, path separation is at least 1 unit.
2nd, it is unable to juxtaposition between each path.
3rd, individual paths length can not less than 2 units.
4th, arc path can not be placed, if there is arc path that multistage straight line path should be used approximately to replace.
5th, end points should be placed around as vacancy.
6th, path can not be placed at frame.
7th, monitoring point must be placed at end points.
8th, outlet must be placed at end points.
Change route map restriction rule：
1st, two end points of selective erasing route are necessary for two end points being joined directly together.
2nd, blank space can not be wiped.
3rd, two points of selective erasing route must be end points/outlet/monitoring point.
2nd, serial ports is selected
Selection, which is connected with, from serial ports column evacuates No. COM that guiding collects end, and connection evacuation guiding collects end.
3rd, the stage is debugged
Green block occurs in the place that enable has road on debugging function, map interface near test point, by yellow block
Extra exit direction indication when the direction for pointing to green block is without the condition of a fire at this.Because each evacuation installed in corridor is drawn
Lead terminal not having with the route map drawn to connecting, it is therefore desirable to do the docking of evacuation guiding terminal and the calibration in direction.
The docking button of evacuation guiding terminal is pressed, makes direction and software plan that the channeling direction indicator lamp of evacuation guiding terminal is indicated
Direction it is consistent, then click on corresponding monitoring point in drawn route map, complete the evacuation guiding terminal docking and
The calibration in direction.Then configuration parameter is preserved using preservation function.
4th, emulation and operation
Before using the system, in-circuit emulation functional check system must be used whether normal.In-circuit emulation is one
Plant in the case of without the condition of a disaster, set some monitoring point to monitor the condition of a fire or gas leakage state manually by this software, then
Check whether route planning function is planned correctly, each evacuation guiding terminal function whether working properly.
When monitoring point is arranged to detect fire or gas leakage, the color of the test point can redden, and plan direction
Meeting respective change, planning direction is the direction that green block is pointed to by red block.While each being mounted everywhere in observation corridor
Whether evacuation guiding terminal direction indication changes, if the route planning with software plan is consistent.Otherwise it should reexamine thin
Dissipate the docking of guiding terminal and the calibration in direction.
If checking errorless above, emulation is closed, can then enter commencement of commercial operation state.When blinker is without the condition of a disaster
The escape way direction of acquiescence is indicated, occurs to indicate escape direction according to system command during the condition of a disaster.
Evacuation arithmetic principle：
1st, array is initialized
If there is N number of node, the null matrix for N*N apart from array Dis and path array path is initialized.
Then two array assignments are given according to the connection of N number of node.It is 1 to N to make A, B, C value, the mutual not phase of A, B, C
Deng Dis (A, A)=0.If point A and point B are joined directly together, distance is S, then Dis (A, B) and Dis (B, A)=S；If A and C is not straight
Connect connected, then Dis (A, C) and Dis (C, A) is infinity.After array Dis assignment is finished, if Dis (A, B) value is not
Infinity, then Path (A, B)=B.Using above-mentioned rule to the whole assignment of two N*N arrays.
2nd, given according to the condition of a fire order of severity and be multiplied by respective weights apart from array Dis
If A nodes occur without fire or gas leakage, all data of A rows of Dis arrays, A arranges all data and is multiplied by one.
If A points have fire or gas leakage, all data of A rows, A arranges all data and is multiplied by the weight for representing the fire order of severity
f.The weights make distance be more than whole map length, represent obstructed at this, and when all outlet ports monitor fire, again can be with
Compare these distances, find out a fire degree most light evacuation route.
3rd, traversal is solved
Solution is traveled through by the way of triple for circulations, the traversal to intermediate node X is placed on outermost loop, to A and B
Traversal be placed on interior loop, A, B, X are traveled through from 1 to N, using regular Dis (A, B)=min Dis (A, X)+Dis (X, B),
Dis (A, B) } all values of Dis arrays are updated, and when meeting Dis (A, X)+Dis (X, B)<During Dis (A, B), make
Path is updated with path (A, B)=path (A, X) rules.
4th, distance and path extraction
The corresponding numerical value D of Dis (A, B) are A to B beeline, and corresponding path is extracted from path arrays, first
Path (A, B) numerical value M is found, path (M, B) numerical value of N is then looked for, then looks for path (N, B) numerical value Z, the like, directly
To find path (L, B) numerical value be B, then it represents that found terminal.It can thus be concluded that the beeline to A to B is D, most short distance
It is from corresponding path：A->M->N->Z...->L->B.
