Description

Technical Field

[0001] The present application relates to the field of satellite communication technology, and in particular to a satellite communication time compensation method, device, electronic equipment and storage medium. Background Art

[0002] In the field of satellite communications, the study of communication time synchronization is an important topic in the development of satellite technology. Especially in the case of direct communication between the terminal and the satellite, due to the relatively long distance between the satellite and the terminal, some delays will inevitably occur. If the time cannot be different, communication frames may be lost. Therefore, the existing communication time compensation technology is to set the communication compensation time in advance, that is, the time when the terminal sends the communication information is A, and compensate the satellite for the communication time deviation T through the protocol, so as to parse the communication information sent by the target terminal at time A.

[0003] However, the inventors of this application discovered that the existing communication time compensation technology sets a time compensation protocol in advance, and its compensation time is fixed, that is, the compensation time is certain within the time of the terminal and satellite communication service, which then causes a large change in the altitude of the terminal in a short period of time, such as when the terminal is traveling in an area with a high altitude difference. As the terminal altitude changes, the distance between the terminal and the satellite will also change, which will cause the actual communication time compensation between the terminal and the satellite to change. Therefore, if the existing communication time compensation technology is used for time compensation, communication frame loss will occur, that is, the accuracy of the communication time compensation will be reduced.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0040] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] An embodiment of the present application provides a satellite communication time compensation method, which can be executed by an electronic device, wherein the electronic device can be a server, wherein the server can be an independent physical server, or a server cluster or distributed device composed of multiple physical servers, or a cloud server providing cloud computing services; the server can be installed in a ground communication terminal.

[0042] Reference Figure 1 A satellite communication time compensation method includes: step S101, step S102 and step S103, wherein:

[0043] S101 , when a target terminal is located and running in a target orbit, obtain location information of the target terminal, first running information of a target satellite corresponding to the target terminal, and a communication time compensation data set corresponding to the target orbit.

[0044] In some embodiments, the target terminal may be a communication terminal installed in a vehicle such as a car or a high-speed train that runs on a specific track; the target track is the road on which the target terminal runs; and the first operation information includes information such as the operation altitude and the operation trajectory.

[0045] During the communication process between the target satellite and the target terminal, due to the influence of the communication distance, there is a time deviation between the target terminal's sending of communication information and the satellite's reception of the communication information. Therefore, when the two communicate, the target terminal and the satellite need to synchronize the communication time; in remote mountainous areas, the target terminal is greatly affected by the terrain altitude. When the target terminal is operating in an orbit located in a remote mountainous area, the altitude of the target terminal will change significantly, and the frequency of its change will also be high.

[0046] Therefore, the electronic device will monitor the position of the target terminal in real time, and when it is monitored that the target terminal is running in the target orbit, it indicates that the altitude of the target terminal itself will change significantly during the subsequent operation; then, when the target is running in the target orbit, the logical steps of determining the communication time compensation data between the subsequent target terminal and its corresponding target satellite are started, that is, the electronic device starts to obtain the position information of the target terminal, the first operation information of the target satellite that establishes a communication service with the target terminal, and the communication time compensation data set corresponding to the target orbit where the target terminal is located, and subsequently uses the position information, the first operation and the communication time compensation data set as the basic data for determining the communication time compensation data corresponding to the target terminal.

[0047] S102: Determine target communication time compensation data corresponding to the target terminal based on the location information, the first operation information, and the communication time compensation data set.

[0048] In some embodiments, the electronic device uses the position information and the first operation information as basic parameters for filtering the target communication time compensation data corresponding to the target terminal, that is, the electronic device substitutes the position information and the first operation information into the communication time compensation data set corresponding to the target track, and filters out the target communication time compensation data corresponding to the target terminal from the communication time compensation data set.

[0049] In some embodiments, the communication time compensation data set includes second operation information of a plurality of initial satellites, a plurality of sub-target orbits in the target orbit, and altitude information corresponding to the target orbit.

[0050] S103: Perform communication time compensation on the target satellite based on the target communication time compensation data.

[0051] In some embodiments, after the electronic device determines the target communication time compensation data, it sends the target communication time compensation data to the target satellite. The target satellite adjusts its communication time based on the received target communication time compensation data, so that the target satellite receives the communication information at the time after the communication time is adjusted, thereby reducing the occurrence of communication information frame loss caused by communication time asynchrony, and utilizing the communication time compensation data set constructed in advance, and when the target satellite needs to adjust the communication time, directly filter out the target communication time compensation data from the communication time compensation data set, thereby improving the accuracy of communication time compensation determination.

[0052] In some embodiments, the communication time compensation data set in step S101 is constructed by the following steps: obtaining orbital information of the target orbit and second operating information corresponding to multiple initial satellites, wherein the orbital information includes orbital altitude information and orbital path information; based on the orbital altitude information, dividing the target orbit into sections to obtain multiple sub-target orbits; based on the orbital path information and the second operating information, determining the pre-communication time compensation data groups corresponding to the multiple sub-target orbits; and using the pre-communication time compensation data groups, multiple sub-target orbits, and orbital altitude information to construct a communication time compensation data set.

[0053] In some embodiments, different satellites have different orbits and altitudes, and therefore, the satellites that establish communication services with the target terminal may also be different; therefore, when constructing a communication time compensation data set, it is possible to consider constructing the operating information of multiple satellites that can provide communication services for the target orbit and the communication time compensation data that need to be compensated for the communication time of the multiple satellites into the communication time compensation data set, thereby ensuring that the target terminal operating in the target orbit can quickly complete the compensation for the communication time of the target satellite when communicating with different satellites.

[0054] In some embodiments, during the process of constructing a communication time compensation data set, the electronic device first obtains orbital information including orbital altitude information, orbital path information, and second operating information corresponding to multiple initial satellites that can provide communication services for the terminal operating in the target orbit; then, the target orbit is divided into sections using the orbital altitude information to obtain multiple sub-target orbits; the electronic device uses the sub-target orbit as a reference, and uses the orbital path information, the second operating information, and the orbital altitude information to determine the distance between the terminal and its corresponding target satellite, and based on the distance, finally determines the pre-communication time compensation data groups corresponding to the multiple sub-target orbits, wherein the pre-communication time compensation data group includes the communication time compensation data of at least two initial satellites, that is, each sub-target orbit corresponds to at least two initial satellites that can provide communication services for the terminal operating therein, and the communication time compensation data corresponding to the determined at least two initial satellites are integrated to obtain the pre-communication time compensation data group; thereafter, the electronic device integrates all the sub-target orbits, the pre-communication time compensation data group corresponding to each sub-target orbit, and the altitude information to construct a communication time compensation data set.

[0055] In some embodiments, based on the track altitude information, the target track is divided into sections to obtain multiple sub-target tracks, including: determining the altitude difference information of the target track based on the track altitude information; dividing the altitude difference information based on a preset altitude difference division rule to obtain multiple sub-altitude difference information; defining the track sections corresponding to the multiple sub-altitude difference information as sub-target tracks to obtain multiple sub-target tracks.

[0056] In some embodiments, the track altitude information includes the altitude information at each traffic sign position of the target track. The electronic device subtracts the altitude information at each traffic sign position from the altitude information at the adjacent previous traffic sign position to obtain multiple initial altitude difference information corresponding to the target track, and integrates the multiple initial altitude difference information to obtain the altitude difference information of the target track; then, the electronic device calls a preset altitude difference division rule, and determines whether a preset number of adjacent initial altitude difference information are all positive or negative based on the preset altitude difference division rule. When the preset number of initial altitude difference information are all positive or negative, the preset number of initial altitude difference information are integrated to obtain sub-altitude difference information. When all the initial altitude difference information are divided, the electronic device defines the track sections corresponding to the multiple sub-altitude difference information as sub-target tracks, thereby obtaining multiple sub-target tracks. The preset number is not specifically limited in the embodiment of the present application, and its specific value can be subjectively set by technical personnel based on the actual situation of the corresponding target track.

[0057] In some embodiments, based on the orbital path information and the second operating information, pre-communication time compensation data groups corresponding to multiple sub-target orbits are determined, including: based on the orbital path information and the second operating information, at least two target operating information corresponding to multiple sub-target orbits are screened out from the second operating information corresponding to multiple initial satellites; target communication ranges of the initial satellites corresponding to at least two target operating information and sub-orbit altitude information corresponding to multiple sub-target orbits are obtained; based on the target communication ranges, sub-orbit altitude information and target operating information, pre-communication time compensation data groups corresponding to multiple sub-target orbits are determined.

[0058] In some embodiments, the second operation information includes the communication range of the initial satellite, which is the range that can provide communication services to the terminal; in the process of constructing the pre-communication time compensation data group, the electronic device determines the communication range of each initial satellite from the second operation information, and compares the communication range with the orbital path information in terms of area and position, and selects at least two target operation information corresponding to multiple sub-target orbits from the second operations corresponding to multiple initial satellites; at the same time, the electronic device obtains the target communication range of the initial satellite corresponding to at least two target operation information and the sub-orbit altitude information corresponding to multiple sub-targets.

[0059] Subsequently, the electronic device uses the target communication range as the driving range of the terminal traveling on the sub-target orbit, and uses the sub-orbit altitude information and the target operation information of the initial satellite providing communication services to the terminal as the basic parameters for determining the communication time compensation data between the terminal and the initial satellite, and determines the pre-communication time compensation data group corresponding to traveling on the sub-target orbit, wherein the pre-communication time compensation data includes the communication time compensation data corresponding to at least two initial satellites and the satellite information of at least two initial satellites.

[0060] In step S102, based on the position information, the first operation information and the communication time compensation data set, the target communication time compensation data corresponding to the target terminal is determined, including: based on the position information, determining the sub-target orbit corresponding to the target terminal; based on the sub-target orbit, filtering out the pre-communication time communication time compensation data group corresponding to the target terminal from the communication time compensation data set; based on the first operation information, filtering out the target communication time compensation data from the pre-communication time compensation data group.

[0061] In some embodiments, the electronic device substitutes the location information of the target terminal into the target orbit, determines the sub-target orbit where the target terminal is located at the current moment, and then, the electronic device substitutes the sub-target orbit into the communication time compensation data set, filters the data in the communication time compensation data set, and obtains the pre-communication time compensation data group corresponding to the target terminal; then, the electronic device substitutes the satellite information contained in the first operation information into the pre-communication time compensation data group containing satellite information corresponding to at least two initial satellites for comparison, and filters out the communication time compensation data corresponding to the target terminal, and the electronic device uses the communication time compensation data as the target communication time compensation data.

[0062] In some embodiments, taking into account the situation that the target track is divided into multiple sub-target tracks, the target terminal is about to leave the current sub-target track and enter the next adjacent sub-target track, when the target terminal leaves the current sub-target track, it is necessary to determine the communication time compensation data group corresponding to the next adjacent sub-target track from the communication time compensation data set set in advance, and determine a new target communication time compensation data group from the communication time compensation data, that is, the target communication time compensation data is determined from the communication time compensation data set too frequently, and there is a situation where the target communication time compensation data is not determined in time. Therefore, it can be considered that in the above situation, while determining the target communication time compensation data of the target terminal at the current moment, the target communication time compensation data when the target terminal enters the next adjacent sub-target track is also determined.

[0063] That is, after determining the sub-target orbit corresponding to the target terminal based on the position information, the target communication time compensation data corresponding to the target terminal is determined based on the position information, the first operation information and the communication time compensation data set, and also includes: determining the target distance information corresponding to the target terminal based on the position information and the sub-target orbit, wherein the target distance information is the distance information of the target terminal from the current position to the sub-target orbit; when the target distance information is less than the preset distance information, determining the communication time compensation data when the target terminal is located at the next sub-target orbit adjacent to the sub-target orbit.

[0064] In some embodiments, the electronic device substitutes the location information into the sub-target track, and calculates the distance between the location information and the endpoint of the sub-target track in the same direction of travel as the target terminal to obtain the target distance information corresponding to the target terminal. Subsequently, the electronic device retrieves the preset distance information and compares and analyzes the target distance information with the preset distance information.

[0065] When the electronic device determines that the target distance information is less than the preset distance information, it indicates that it is necessary to determine the target communication time compensation data of the target terminal at the current moment, and also needs to determine the target communication time compensation data when the target terminal enters the next adjacent sub-target orbit. Then, the electronic device predicts the target satellite when the target terminal reaches the next adjacent sub-target orbit based on the current operating speed, and obtains the operating information of the target satellite, and substitutes the position information of the target terminal when it reaches the next adjacent sub-target orbit and the operating information of the target satellite into the communication time compensation data set, thereby filtering out the communication time compensation data when the target terminal is located in the next sub-target orbit adjacent to the sub-target orbit; the electronic device uses the communication time compensation data as pre-sent data, and stores it in the storage space as priority transmission data.

[0066] In step S103, communication time compensation is performed on the target satellite based on the target communication time compensation data, including: setting a data sending rule corresponding to the target communication time compensation data, and sending the target communication time compensation data to the target satellite based on the data sending rule to compensate for the communication time of the target satellite, wherein the data sending rule is to send the target communication time compensation data to the target satellite at the end of a preset time period after the previous communication information adjacent to the communication information corresponding to the target communication time compensation data is sent.

[0067] In some embodiments, after the electronic device determines the target communication time compensation data, it will set its corresponding data sending rules. The data sending rules are to start timing the preset time period after the target terminal completes sending the previous batch of communication information adjacent to the current batch of communication information and is received by the target satellite; after the preset time period is completed, the electronic device sends the target communication time compensation data to the target satellite, wherein the preset time period can be set based on the time period between the sending time of the current batch of communication information and the sending time of the previous batch of communication information, and the preset time period is less than the time period. The specific setting value of the preset time period is not specifically limited in the embodiment of this application and can be specifically set by technical personnel based on actual conditions; then, the electronic device uses the data sending rules to send the target communication time compensation data to the target satellite, and the target satellite performs communication time compensation based on the target communication time compensation data.
