Divide in the level-one set on vertex, similarly, falls in the vertex in second level alarm buffer area, then the information of current shaft tower is stored in this
In the second level set on part vertex, the vertex in three-level alarm buffer area is fallen in, then the information of current shaft tower is stored in this portion
Divide in the three-level set on vertex.So far, then the corresponding grid vertex of current shaft tower can be associated, that is, completed current
The pre-stored of shaft tower information.
105, it determines next shaft tower in target area, re-executes 103 for next shaft tower as current shaft tower, until complete
The information storage of all shaft towers in pairs of target area；
Due to having a certain number of shaft towers in target area, it, then can be with after by current shaft tower information pre-stored
It determines next shaft tower, re-execute the steps 103, until all shaft towers in target area complete information pre-stored.
It should be noted that then need to only be re-execute the steps to new shaft tower when there is newly-increased shaft tower in target area
103 and 104, complete timely updating for shaft tower information with can be convenient.
106, the set on four vertex corresponding to each grid carries out set operation, obtains the shaft tower alarm of each grid
Class information；
After completing shaft tower information pre-stored, then set operation can be carried out one by one to each grid.Specifically, set operation
Process are as follows:
(a) current grid is determined；
(b) the level-one set on four vertex of current grid is subjected to union operation, obtains the first order bar of current grid
Tower warning information；
(c) by the second level set on four vertex of current grid carry out after union operation again with first order shaft tower warning information
Set difference operation is carried out, the second level shaft tower warning information of current grid is obtained；
(d) it is successively alerted again with first order shaft tower after the three-level set on four vertex of current grid being carried out union operation
Information, second level shaft tower warning information carry out set difference operation, obtain the third level shaft tower warning information of current grid；
(e) it determines next grid and using next grid as current grid, re-executes (a) until obtaining target area
The shaft tower of all grids alerts class information.
After the shaft tower alarm class information calculating for completing all grids, then it can be numbered with grid by the shaft tower of each grid
Alarm class information is stored, so as to subsequent extraction and output.
107, after occurring fire point in target area, the shaft tower alarm class information of grid where extracting and exporting fire point.
In the present embodiment, after occurring fire point in target area, the latitude and longitude coordinates of fire point can first be determined, further according to
The latitude and longitude coordinates of fire point carry out grid location, the shaft tower alarm class information of grid where then extracting and exporting fire point.
