The weapon is to represent the battle unit with chessmen (operators), the battle field with chessboard (cellular map), and the battle action with the movement of chessmen on the chessboard. According to war experience, the probability of the occurrence of a battlefield event is compiled into a decision table; judging the action result by a method of searching event results from the judging table in a mode of generating random numbers; a combat simulation tool for simulating a combat decision by using a round trip system; the chess deduction has become one of the effective combat deduction and training means accepted by the major military countries in the world. The ground communication system is One of important components of weapon deduction, and satellite cellular network communication systems are widely spread and rapidly developed in recent years, for example, iridium, one Web, starlink and the like are known satellite cellular network communication systems. Compared with a ground cellular network communication network system, the satellite has the characteristics of no terrain limitation, wide coverage area, flexible networking and the like because the satellite is in a space far away from the ground surface.
The satellite cellular network communication system plays an increasingly important role in the fields of navigation positioning, civil communication, remote sensing monitoring, weather prediction and the like, and particularly when an irresistible natural disaster occurs, the satellite cellular network communication system can provide more perfect rescue service for trapped people and rescue personnel, so that the importance of the satellite cellular network communication system is continuously improved, and the satellite cellular network communication system is an important component for realizing global communication. The current planning method of satellite cellular network mainly utilizes the periodic and predictable motion law of satellite system, and can divide a complete area into a plurality of determined time periods, in each time period of the plurality of determined time periods, the satellite position is considered to be unchanged, namely in a fixed state, one state is defined as a snapshot, and then the best scheme of other connectable satellites and ground stations is determined for each snapshot. The traditional satellite cellular network can cover a limited space range, and meanwhile, space targets are difficult to form corresponding display on a chessboard as ground targets, so that the addition of a large number of space targets and ground stations cannot be realized, and the dynamic presentation of a planning and building scheme of the large-range satellite communication cellular network and the visual analysis of signal coverage can not be supported.
Example 1
The execution subject of the satellite cellular network planning method based on the chess chessboard is a server.
The method for planning a satellite cellular network based on a chess board provided by the embodiment refers to a flow chart of the method for planning a satellite cellular network based on a chess board shown in fig. 1, and the method is applied to a satellite communication system and comprises the following specific steps:
Step 100: creating a two-dimensional world map, importing the two-dimensional world map into the satellite communication system and generating a chessboard.
In the step 100, the two-dimensional planar world map is selected to have a larger scale, a smaller deformation of the actual measurement length and area, and to avoid complex calculation. Preferably, the two-dimensional planar world map created above may use a two-dimensional planar world map drawn by three-degree banding of gaussian-kriging projections. The two-dimensional planar world map drawn by the gaussian-g three-dimensional banding method exists as a checkerboard base map in a checkerboard.
Step 101: dividing the chessboard by longitude and latitude, forming a plurality of grids in the chessboard, and determining satellites and ground stations positioned in each grid.
In the step 101, the grids in the chessboard are divided by the weft and the warp, and the divided grids have a certain range.
And (3) corresponding the satellite or the ground station to the chess grid where the coordinates of the satellite or the ground station are located, so as to determine the chess grid where the satellite or the ground station is located. The coordinates of the points below the satellite are points of intersection of the connecting line of the center of the earth and the satellite on the surface of the earth; thus, each satellite or ground station corresponds to a checkerboard.
Step 102: and selecting a plurality of adjacent chess grids from the chessboard to form a first target area for establishing a satellite communication cellular network.
In step 102 described above, the first target area is the area selected by the worker using the input device on the server.
Step 103: and acquiring satellite selection conditions, determining a main satellite of the first target area based on the acquired satellite selection conditions, and determining a ground station positioned in the same chess lattice as the main satellite.
In step 103, the satellite selection condition means that in the process of selecting and establishing the first target area of the satellite communication network, different actual use requirements will also have different requirements on the communication quality of the satellite, and if the communication quality of the selected satellite is too high, the resource waste will be caused; if the communication quality of the selected satellite is too low, the actual use requirement cannot be met; therefore, satellite selection conditions are set according to different practical use requirements, and satellites are screened by taking the satellite selection conditions as a standard. The satellite cellular communication network consists of satellites and ground stations, wherein the ground stations corresponding to the chess grids of the main satellites are selected ground stations, and the main satellites and the ground stations are determined so as to facilitate the construction of subsequent satellite cellular networks.
Specifically, the satellite's undersea point coordinates should be within the first target region.
Step 104: a plurality of slave satellites within the first target region that establish communication links with the master satellite are determined.
In the step 104, the slave satellite of the master satellite may be a satellite within a preset number nearest to the master satellite from among satellites not selected as the master satellite in the first target area.
In one embodiment, the number of slave satellites is determined by the master satellite, and the preset number of slave satellites to which the master satellite can connect is four.
Then, from among satellites located in the first target area that are not selected as the master satellite, less than or equal to 4 satellites may be selected as the slave satellites of the master satellite.
Step 105: and constructing a satellite cellular network in the first target area through the main satellite, a plurality of auxiliary satellites and a ground station which is positioned in the same chess lattice with the main satellite.
In step 105, the master satellite and the ground station are located in the same grid, and the master satellite and the slave satellite may be located in the same grid or different grids, but the master satellite and the slave satellite must be located in the first target area.
Step 106: and determining and displaying the coverage area of the established satellite cellular network in the first target area according to the satellite point coordinates of the main satellite of the satellite cellular network and each satellite in the plurality of satellites.
In step 106, the satellite point coordinates of the slave satellites are consistent with the satellite point coordinates of the master satellite, which is not described herein.
The satellite cellular network is applied to the mobile station, and the signal coverage of the satellite cellular network can be presented on the mobile station by means of colored area marks; the mobile station refers to wireless handheld mobile terminal equipment; in particular, the chess grid on the chessboard is a regular polygon, and the shape presented by the coverage area of the satellite cellular network on the chessboard can be a regular polygon or other irregular shapes, and the method is not limited in the embodiment.
Further, when the master satellite leaves the first target area, the communication link between the master satellite and each slave satellite is disconnected, and the satellite cellular network in the first target area is released.
In particular, the position of the satellites is not fixed, and the position of the satellite cellular network on the chessboard is changed either when the orbit of the main satellite is changed or when the main satellite is moved out of the first target area. Referring to a satellite cellular network position change flow chart of a satellite cellular network planning method based on a chess chessboard shown in fig. 2, the satellite cellular network position change needs to undergo the following steps:
Step 200: the main satellite moves out of the first target area and moves to a new chess grid;
Specifically, if the movement of the main satellite is manual, the main satellite moves from the point A of the chessboard to the point B of the chessboard according to the plan until the main satellite stops moving to the target chess grid. When the main satellite moves to the target chess grid, the ground station corresponding to the target chess grid is connected with the main satellite.
Step 201: the original satellite cellular network location in the first target area is changed;
Specifically, after the primary satellite moves, the communication connection between the primary satellite and the ground station and the secondary satellite in the first target area is gradually interrupted as the primary satellite gradually moves out of the first target area. Meanwhile, the main satellite and the new auxiliary satellite can continuously establish a new connection relation in the moving process until the auxiliary satellite determined after the main satellite moves to the target chess grid is not replaced.
Step 202: new slave satellites around the new chess grid of the master satellite are displayed on the chessboard;
specifically, after the main satellite moves to a new chess grid (target chess grid), satellites capable of establishing connection with the main satellite are displayed on the chess board. The main satellite sequentially selects four satellites closest to each other according to the distances to establish a subordinate connection relationship.
Step 203: establishing a new satellite cellular network scheme according to the need;
In particular, the new satellite cellular network may be scaled up or down according to different requirements, and it may be necessary to increase or decrease the number of connections to the satellite while simultaneously expanding or shrinking the signal coverage area. In particular, the master satellite can increase the number of slave satellites to 4 at the maximum.
Step 204: displaying the coverage range of the new satellite cellular network on the chessboard;
In particular, to more intuitively present the position movement of the satellite cellular network coverage on the chessboard, the new satellite cellular network coverage established by the master satellite and the new slave satellite can be colored marked differently from the old satellite cellular network coverage color.
It should be noted that the second target area may be designated to establish a new satellite cellular network only when the first satellite cellular network is established, manually, or when the primary satellite is manually controlled to move. Otherwise, without human intervention, the location of the new satellite cellular network established after the primary satellite has moved out of the first target area is uncertain.
In summary, a two-dimensional world map is built in a satellite communication system, a chessboard is generated, the chessboard is divided into a plurality of chessmen by warps and wefts, a plurality of chessmen are selected and are determined to be a first target area, a main satellite, a ground station and a plurality of subordinate satellites are determined by using the first target area, a satellite cellular network is formed by using the main satellite, the ground station and a plurality of subordinate satellite components, and the coverage area of the satellite cellular network is presented on the chessboard; compared with the prior art that the satellite cannot correspond to the chessboard in position and the satellite cellular network cannot be visually presented, the satellite can be displayed on the chessboard through the corresponding chess lattice, the positions of the ground station and the slave satellite on the chessboard can be determined by utilizing the main satellite, and the main satellite, the ground station and the slave satellite component form the satellite cellular network and then can be presented on the chessboard, so that the visual simulation of the satellite cellular network on the chessboard is more visual.
