Description

Technical Field

[0001] The present application relates to the technical field of satellite remote control, and in particular, to a communication time synchronization method, device, electronic device and medium for a satellite and a terminal. Background Art

[0002] With the continuous development of satellite communication technology, the interconnection communication between satellites and terminals has now been realized. Therefore, the remote control of terminals through satellites has also been achieved. Before using satellites to remotely control terminals, it is necessary to synchronize the communication time between satellites and terminals to solve the problems that communication information cannot be parsed and / or there are deviations in the execution time. The existing method for synchronizing the communication time between satellites and terminals is that satellites and geostationary satellites perform time synchronization through GNSS components, and the time of the terminals is also determined by geostationary satellites, so as to achieve the time synchronization between satellites and terminals.

[0003] However, the inventors of the present application found that during the process of the satellite performing precise motion control on the terminal, due to the high requirements of precise motion, the requirements for time synchronization between the satellite and the terminal will also be higher, and precise motions often do not exist alone and need to continuously complete a series of precise motions; after synchronizing the communication time between the satellite and the terminal through the target geostationary satellite, during the process of the satellite controlling the terminal to complete a series of precise motions, as time goes by, the time between the satellite and the terminal deviates, resulting in a decrease in the accuracy of the communication time synchronization between the satellite and the terminal.

DETAILED DESCRIPTION

[0041] The following will Figures 1 - 3 describe this application in further detail with reference to the

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0043] The embodiments of this application provide a communication time synchronization method between a satellite and a terminal, which can be executed by an electronic device. Among them, the electronic device can be a server. The server can be an independent physical server, a server cluster or a 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.

[0044] Refer to Figure 1 , a communication time synchronization method between a satellite and a terminal includes: step S101, step S102, step S103, and step S104. Among them,

[0045] S101, screen out at least two groups of inspection action information from the obtained pre-execution action information of the terminal to be controlled, and retrieve the execution standards corresponding to at least two groups of inspection action information.

[0046] In some embodiments, the terminal to be controlled is a terminal device remotely and precisely controlled by a satellite; the pre-execution action information is the action information of all actions that the terminal to be controlled needs to execute when performing a certain action task; the inspection action information is the verification action information used to determine the communication time compensation between the terminal to be controlled and the target satellite; the execution standard is the execution requirement that the terminal to be controlled needs to meet when executing at least two groups of inspection action information. The execution standard includes the starting time point when the terminal to be controlled executes the action, the implementation time period from the start of execution to the completion of execution by the terminal to be controlled, and the time interval between the completion of the previous group of inspection action information and the start of execution of the next group of inspection action information by the terminal to be controlled.

[0047] The electronic device obtains the action task that the terminal to be controlled is about to execute, performs action analysis and splitting on the action task, and obtains all the actions that the terminal to be controlled needs to execute when performing this action task. Subsequently, the electronic device defines the action information of all actions as pre-execution action information, and based on certain screening requirements, screens the pre-action information, screens out at least two groups of inspection action information from it. At the same time, the electronic device obtains the execution standards corresponding to at least two groups of inspection action information respectively, and uses this execution standard as the basic data for judging whether there is a deviation in the communication time when the subsequent terminal to be controlled actually executes at least two groups of inspection action information.

[0048] S102. Generate action execution instructions corresponding to at least two groups of inspection action information, and control the target satellite to control the to-be-controlled terminal to complete actions based on the action execution instructions and the at least two groups of inspection action information.

[0049] In some embodiments, after the electronic device filters out at least two groups of inspection action information from the pre-execution action information and obtains their corresponding execution standards, it starts to perform action execution verification. That is, the electronic device generates action execution instructions corresponding to the at least two groups of inspection action information, and sends the action execution instructions and the at least two groups of inspection action information to the target satellite. The target satellite responds to the action execution instructions and sends control information to the to-be-controlled terminal based on the at least two groups of inspection action information. The to-be-controlled terminal responds to the control information to complete the actions corresponding to the at least two groups of inspection action information. Among them, the target satellite can be a low-earth orbit satellite or a medium-high earth orbit satellite.

[0050] S103. Obtain the execution result corresponding to the to-be-controlled terminal, where the execution result is the execution situation of the to-be-controlled terminal completing at least two groups of inspection action information.

[0051] In some embodiments, when the to-be-controlled terminal completes the actions corresponding to at least two groups of inspection action information, the electronic device sends an execution result acquisition instruction to the to-be-controlled terminal. The to-be-controlled terminal responds to the execution result acquisition instruction and obtains the execution results such as the time data and action data recorded during the process of the to-be-controlled terminal performing actions based on the at least two groups of inspection action information from the storage module installed inside it. The to-be-controlled terminal sends the execution result to the electronic device.

[0052] S104. Determine communication time compensation information based on the execution standard and the execution result, and synchronize the communication time of the target satellite and the to-be-controlled terminal based on the communication time compensation information.

[0053] In some embodiments, the electronic device compares and analyzes the relevant data included in the execution standard with the relevant data included in the execution result based on a certain comparison and analysis rule, so as to determine the action execution time difference between the action execution of the to-be-controlled terminal based on the execution standard and the actual action execution, and determine the communication time compensation data for compensating the communication time of the to-be-controlled terminal and the target satellite based on the action execution time difference.

[0054] Subsequently, the electronic device sends the communication time compensation information to the target satellite and the to-be-controlled terminal, enabling the target satellite and the to-be-controlled terminal to perform time adjustment based on the communication time compensation information to complete the communication time synchronization between the target satellite and the to-be-controlled terminal; thereby, by screening out appropriate verification actions from the actions that the to-be-controlled terminal needs to execute and in the way of real experiments, determining the time deviation between the execution result after the to-be-controlled terminal executes the action and the execution standard to determine the communication time compensation information, thus improving the accuracy of the communication time synchronization between the target satellite and the to-be-controlled terminal.

[0055] In some embodiments, the pre-execution action information of the to-be-controlled terminal is obtained through the following steps: obtaining the first initial communication time synchronization information of the to-be-controlled terminal and the second initial communication time synchronization information of the target satellite; in the case where the time difference between the first initial communication time synchronization information and the second initial communication time synchronization information is less than the preset time difference, obtaining the pre-execution action information of the to-be-controlled terminal.

[0056] In some embodiments, the first initial communication time synchronization information and the second initial communication time different information are the communication time synchronization information after the communication time synchronization between the target satellite and the to-be-controlled terminal is completed based on the geostationary satellite.

[0057] Before conducting real-scenario experiments using the screened test action information, it is necessary to determine whether the communication time synchronization between the target satellite and the to-be-controlled terminal using the geostationary satellite is completed. Therefore, before the electronic device screens out at least two groups of test action information from the pre-execution action information, it obtains the first initial communication time synchronization information from the to-be-controlled terminal and the second initial communication time synchronization information from the target position; subsequently, the electronic device compares the first initial communication time synchronization information and the second initial communication time synchronization information to obtain the time difference between the two; the electronic device compares this time difference with the preset time difference, and in the case where it is determined that the time difference is less than the preset time difference, it indicates that the communication time synchronization between the target satellite and the to-be-controlled terminal using the geostationary satellite is completed, and then the electronic device obtains the execution action information of the to-be-controlled terminal.

[0058] In some embodiments, the pre-execution action information includes multiple groups of action information; therefore, in step S101, screening out at least two groups of test action information from the obtained pre-execution action information of the to-be-controlled terminal includes: obtaining the execution time corresponding to each group of action information and the action execution time interval between two adjacent groups of action information; screening the multiple groups of action information based on the execution time and the action execution time interval to obtain at least two groups of test action information.

[0059] In some embodiments, the execution time is the time when the terminal to be controlled performs an action based on the action information, and the action execution time interval is the time interval between the times when the terminal to be controlled performs actions for two adjacent sets of action information.

[0060] The electronic device obtains the execution time corresponding to each set of action information and the action execution time interval between two adjacent sets of action information, and uses the execution time as the basic information for the preliminary screening of multiple sets of action information. After the preliminary screening of multiple sets of action information based on the execution time is completed, the electronic device further screens the remaining action information after the preliminary screening based on the action execution time interval, so as to obtain at least two sets of test action information.

[0061] In some embodiments, screening multiple sets of action information based on the execution time and the action execution time interval to obtain at least two sets of test action information includes: preliminarily screening multiple sets of action information based on a preset first time period and the execution time to obtain multiple sets of pre-action information, where the first time period is set based on the initial execution time and the last execution time among multiple execution times; comparing the action execution time intervals between multiple sets of pre-action information with a preset second time period, and defining the two sets of pre-action information corresponding to the action execution time interval greater than the second time period as test action information.

[0062] In some embodiments, the electronic device calls the first time period, compares each of the multiple execution times with the first time period to determine whether the execution time is within the first time period, the electronic device eliminates the execution times that are not within the first time period, retains the execution times that are within the first time period, and defines the action information corresponding to the retained execution times as pre-action information. The multiple sets of pre-action information screened out by the electronic device are continuous and adjacent in time. Among them, the setting of the first time period can be based on the initial execution time and the last execution time among all execution times. For example, the initial execution time among multiple execution times is 0 seconds, and the last execution time is 6 seconds. The initial time point of the first time period can be set based on the initial execution time of 0 seconds, and the termination time point of the first time period can be set based on the last execution time of 6 seconds. The initial time point is greater than the initial execution time, and the termination time point is less than the last execution time. The initial time point and the termination time point can be subjectively set by those skilled in the art, and are not specifically limited in the embodiments of the present application.

[0063] Subsequently, the electronic device compares the action execution time intervals between multiple sets of pre-action information with the preset second time period respectively to determine whether the action execution time interval is greater than the second time period. When the electronic device determines that any action execution time interval is greater than the second time period, the electronic device defines the two sets of pre-action information corresponding to the any action execution time interval as test action information.

[0064] In step S104, based on the execution standard and the execution result, communication time compensation information is determined, including: based on the execution standard, obtaining the action standard execution times corresponding to at least two groups of inspection action information respectively; based on the execution result, obtaining the action actual execution times corresponding to at least two groups of inspection action information respectively; and determining the communication time compensation information based on the action standard execution time and the action actual execution time.

[0065] In some embodiments, the action standard execution time is the ideal execution time when the terminal to be controlled executes the inspection action information, and the action actual execution time is the actual execution time when the target satellite controls the terminal to be controlled to execute the action based on the inspection action information.

[0066] The electronic device analyzes the execution standard and obtains the action standard execution times corresponding to at least two groups of inspection action information respectively from the execution standard; in addition, the electronic device analyzes the execution result and obtains the action actual execution times corresponding to at least two groups of inspection action information respectively from the execution result; the electronic device uses the action standard execution time and the action actual execution time as the basic information for determining the communication time compensation information between the target satellite and the terminal to be controlled.

[0067] In some embodiments, the action standard execution time includes a first execution start time point, a first execution time period, and a first time interval; the action actual execution time includes a second execution start time point, a second execution time period, and a second time interval; determining the communication time compensation information based on the action standard execution time and the action actual execution time includes: comparing the first execution start time point with the second execution start time point, and comparing the first execution time period with the second execution time period; when the first execution start time point is equal to the second execution start time point and the first execution time period is equal to the second execution time period, comparing the first time interval with the second time interval to obtain an action execution time difference; and determining the communication time compensation information based on the action execution time difference.

[0068] In some embodiments, the first execution start time point is the ideal time point when the terminal to be controlled executes the action of the inspection action information, the first execution time period is the ideal time period from the start to the completion of the action of the terminal to be controlled executing the inspection action information, and the first time interval is the ideal time interval from the completion of the action of the terminal to be controlled executing the previous inspection action information to before the action of executing the next inspection action information.

[0069] The second execution start time point is the actual time period from the start to the completion of the action of the target satellite controlling the terminal to be controlled to execute the inspection action information; the second execution time period is the actual time period from the start to the completion of the action of the target satellite controlling the terminal to be controlled to execute the inspection action information; the second time interval is the actual time interval from the completion of the action of the target satellite controlling the terminal to be controlled to execute the previous inspection action information to the start of the action of executing the next inspection action information.

[0070] The electronic device compares the first execution start time point with the second execution start time point to determine whether they are equal. At the same time, the electronic device compares the first execution time period with the second execution time period to determine whether they are equal. When the electronic device determines that the first execution start time point is equal to the second execution start time point and the first execution time period is equal to the second execution time period, it indicates that the relevant control information when the target satellite controls the controlled terminal to execute the inspection action information has packet loss and distortion. Subsequently, the electronic device calculates the difference between the first time interval and the second time interval to obtain the action execution time difference, and the electronic device determines the communication time compensation information based on the action execution time difference.

[0071] In step S104, performing communication time synchronization on the target satellite and the terminal to be controlled based on the communication time compensation information includes: obtaining the satellite time of the target satellite and the terminal time of the terminal to be controlled; using the satellite time or the terminal time as the time reference, and performing time compensation on the satellite time or the terminal time based on the communication time compensation information to complete the communication time synchronization of the target satellite and the terminal to be controlled.

[0072] In some embodiments, when the electronic device completes the action of the previous inspection action information when the target satellite starts to control the terminal to be controlled to execute at least two groups of inspection action information based on the pre-execution action information, the electronic device obtains the satellite time of the target satellite and the terminal time of the terminal to be controlled. Subsequently, the electronic device uses the satellite time and the terminal time as the time reference, and uses the communication time compensation information to perform time compensation adjustment on the satellite time and the terminal time, so as to complete the communication time synchronization of the target satellite and the terminal to be controlled.
