defining a space domain resource state and a space domain resource state transfer condition;
generating a spatial domain resource double-layer grid comprising an upper layer grid and a bottom layer grid which have a mapping relation based on a spatial domain needing to be managed; each upper layer grid and the bottom layer grid of the spatial domain resource double-layer grid show the spatial domain resource state of a corresponding spatial domain; and the displayed spatial domain resource state changes along with the spatial domain resource state transition condition triggered by the trigger event.
Further, the defined spatial resource states include: idle, plan, pre-active, risk, conflict, abort, end, reclaim. In particular, the amount of the solvent to be used,
idle: the current airspace has no unit to use, and no unit plans to use the airspace within a foreseeable period of time;
planning: the current airspace has no unit to use, but a unit plan is to use the airspace within a foreseeable period of time;
pre-activation: the current airspace has no unit to use, and the current airspace is about to be used by a certain unit according to a plan;
activating: units are using current airspace resources;
risk: the space utilization units in the current airspace have mutual influence, or the space between the current airspace and the adjacent airspace used by other units does not meet the safety standard;
conflict: the space domain conflict exists among the space utilization units in the current space domain, or the space domain resources are needed by a plurality of incompatible space domain requirements;
and (3) stopping: the influences of adjustment, environment change and the like are planned, the use of the space domain resources by the current unit is ended in advance, and the space domain is withdrawn by the current empty unit;
and (4) ending: the airspace is used up according to the plan, and the airspace does not have an immediate subsequent use plan, and the current airspace is withdrawn in a single-level mode;
and (3) recovering: the use of the space domain is stopped or ended, the related space domain is also withdrawn by the space unit, and the space domain resource enters a recovery state.
Further, the defined spatial domain resource state transition conditions include: planning, about to start, start use, finding risk, finding conflict, conflict resolution, conflict demotion, abort instruction, unit retirement, complete recycle. The corresponding relation between the airspace resource state and the airspace resource state transfer condition is shown as a table I;
table one, a corresponding relationship table of airspace resource state-airspace resource state transition conditions:
as can be seen from table one, and with reference to fig. 2, the corresponding relationship between the airspace resource state and the airspace resource state transition condition is as follows:
idle > plan: and after the idle airspace use plan is formulated, the idle airspace is converted into a planning state.
Plan > Pre-activation: the airspace in the planning state enters a pre-activation state ten minutes before the latest airspace use plan starting time, and the pre-activation state is a prompt state, so that peripheral units know that the airspace is about to be used by units.
Preactivation > activation: the airspace in the pre-activation state enters the activation state at the latest airspace use plan starting time point, and other units in the activation state need to coordinate with the empty units when needing to temporarily pass through the airspace.
Activation > suspension: and the airspace in the activated state enters the suspended state after receiving the instruction for suspending use and waits for the withdrawal of the empty units.
Activation > end: and the airspace in the activated state enters the ending state after the current plan execution ending time is reached, and the idle unit is waited to withdraw.
Activation > risk: and if the activated state airspace is used together by multiple units or does not meet the safety standard with the adjacent unit interval, entering a risk state.
Activation > conflict: the active state airspace enters a conflict state if incompatible airspace usage modes exist or the environment and enemy seriously threaten the airspace.
Risk > conflict: the airspace status is changed from risk to conflict when the degree of risk brought by the common use of the risk multiple units or the degree of the interval from the adjacent unit not meeting the safety standard exceeds the acceptable range.
Risk > end: and the airspace in the risk state enters an ending state after reaching the current plan execution ending time, and waits for the evacuation of the empty units.
Conflict > abort: when handling a collision situation in a collision state airspace, if it is determined to suspend use of the current airspace, the system enters a suspension state and waits for evacuation of empty units.
Conflict > risk: when dealing with a collision situation in the collision state airspace, if the risk is selected to be accepted or the risk level is reduced by the handling, the airspace state changes from collision to risk.
Conflict > activate: when dealing with the conflict situation of the conflict state airspace, if the conflict is released or the risk is eliminated, the airspace state is changed from conflict to activation.
Suspension > planning: and (4) stopping the state airspace, and entering a planning state if a new airspace use plan is to be executed after the current empty unit is withdrawn.
Abort > recovery: and after the current empty unit is withdrawn from the airspace, if no new airspace use plan is to be executed, the airspace enters a recovery state and waits for resource recovery processing.
And (4) finishing planning: and (4) ending the state airspace, and entering a planning state if a new airspace use plan is to be executed after the current empty unit is removed from the airspace.
End > recovery: and (4) ending the state airspace, and after the current empty unit is withdrawn from the airspace, if no new airspace use plan is to be executed, entering a recovery state and waiting for resource recovery processing.
Reclaim > idle: and after the resource information is updated and confirmed, the recovery state airspace enters an idle state from the recovery state to wait for a further use plan.
Further, as shown in fig. 3, the method for generating a spatial domain resource double-layer grid based on a spatial domain needing to be managed specifically includes:
step 1.1, calculating a minimum rectangular bounding box of an airspace needing to be managed; specifically, as shown in fig. 4, based on the vertex coordinates of the airspace (P1, P2, …, P5) to be managed, a rectangle surrounded by intersections of the north-most vertex coordinate latitude line B1B2, the south-most vertex coordinate latitude line B3B4, the west-most vertex coordinate longitude line B1B4, and the east-most vertex coordinate longitude line B2B3 is taken as a minimum rectangle bounding box;
step 1.2, taking one vertex of the minimum rectangular bounding box as a starting point; as shown in FIG. 4, point B1, the local plane coordinate system is established with the east as the positive X-axis direction, the north as the positive Y-axis direction, and the start point as the origin, and the coordinates of the start point are (lat)0，lon0) Conversion to radian expression (α)0，β0)。
Translating the starting point to the east along the longitude direction by a distance r, wherein the coordinates of the translated point are as follows:
X＝r*cos0＝r
Y＝r*sin0＝0
let the radius of the earth be R, then the included angle between the starting point and the translated point to the geocenter is:
then, the radian coordinates corresponding to the translated points are:
α1＝arcsin(cosγ×sinα0)
β1＝β0+atn2(r×sinγ,r×cosα0×cosγ)
and converting the radian in the radian coordinates (alpha, beta) corresponding to the translated point into a degree, namely a longitude and latitude coordinate.
Similarly, the radian coordinates corresponding to the point where the starting point is translated by the distance r along the latitude direction are as follows:
α2＝arcsin(cosγ×sinα0-sinγ×cosα0)
β2＝β0+atn2(0,r×cosα0×cosγ+r×sinα0sinγ)
step 1.3, as shown in fig. 5, taking a longitude translation point obtained by translating the starting point by the minimum distance each time as a line along the latitude direction, taking a latitude translation point obtained by translating the starting point by the minimum distance each time as a line along the longitude direction, and taking all rectangles of the intersection points of the lines, which are divided in the airspace needing to be managed, as bottom grids; and taking a longitude translation point obtained by translating the starting point by 3 times of the minimum distance each time as a line along the latitude direction, taking a latitude translation point obtained by translating the starting point by 3 times of the minimum distance each time as a line along the longitude direction, and taking all rectangles of which the intersection points of the lines are divided in the airspace needing to be managed as upper grids. The intersection point of each upper layer grid and the bottom layer grid is a grid vertex coordinate set, and the specific coordinate can be calculated according to the coordinate calculation mode in the step 1.2. In the above gridding process, the distance may be used as a reference and the longitude and latitude may be used instead.
Furthermore, each upper grid and each bottom grid of the spatial domain resource double-layer grid also show a grid name, a grid vertex coordinate set and the average altitude of a spatial domain corresponding to the upper grid and the bottom grid. For use and retrieval, the grid names, the spatial domain resource states, the grid vertex coordinate sets, and the average elevations of the spatial domains corresponding to the upper grid and the lower grid are stored by using HashMap in a key-value manner, as shown in FIG. 6.
The method for naming the grid name comprises the following steps:
the naming method of the grid name of the upper grid comprises the following steps: the grid name of each upper grid is formed by a line mark, a list and a combination; the north to the south is marked with 0 to N numbers, and the west to the east is marked with A to Z letters; for example, the grid name of the upper grid as the first row and the second column is 0B;
the method for naming the grid name of the bottom grid comprises the following steps: and respectively adding numbers 1-9 to mark after the grid names of the corresponding upper-layer grids from left to right and from top to bottom.
Grid name (m, n) of the upper grid corresponding to the bottom grid in the ith row and the jth column:
wherein the content of the first and second substances,
and
for rounding operation, i is 0-2, and j is 0-2;
the sequence number num of the bottom grid corresponding to the upper grid is as follows:
num＝1+(i％3)×3+(j％3)
wherein,% is the remainder operation. For example, the mesh name of the bottom layer mesh in row 3 and column 3, i being 2 and j being 2, corresponds to the mesh in the top layer mesh in row 1 and column 1, with the serial number 9 being 0a 9.
Further, each time a defined trigger event occurs, a state change process is triggered, and according to the grid level where the changed grid is located, state change mapping is performed on the grid of another layer. Specifically, as shown in fig. 7, the method for changing the airspace resource state along with the triggering of the airspace resource state transition condition includes:
step 2.1, acquiring a trigger event, and determining a grid corresponding to an airspace where the trigger event is located;
step 2.2, judging whether the grid corresponding to the airspace where the trigger event is located is a bottom grid or not; if yes, executing step 2.3; if yes, executing step 2.4;
step 2.3, changing the airspace resource state displayed by the bottom grid according to the airspace resource state transfer condition, and mapping and changing the corresponding airspace resource state displayed by the upper grid;
and 2.4, changing the airspace resource state displayed by the upper grid according to the airspace resource state transfer condition, and mapping and changing the corresponding airspace resource state displayed by the bottom grid.
Further, the mapping relationship of the spatial domain resource states displayed by the upper layer grid and the corresponding bottom layer grid is as follows:
when the same airspace resource state displayed by the bottom grid has no risk and conflict, the airspace resource state displayed by the upper grid is the airspace resource state with the largest number of the same airspace resource states displayed by the corresponding bottom grid;
when the same airspace resource state displayed by the bottom grid is at risk or in conflict, the airspace resource state displayed by the upper grid is at risk.
Further, as shown in fig. 8, due to the overlapping of the double-layer grid in the actual region, when displaying the spatial domain resource state, a layered display method is adopted: the bottom layer grid and the upper layer grid are respectively a layer; each bottom grid and the upper grid show different spatial domain resource states by filling different colors, and the filled colors are changed along with the transition of the spatial domain resource states.
