[0049] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily.
[0050] Figure 1 FIG. 1 is a flow chart of a method for injecting a spacecraft flight program according to an embodiment of the present invention. Figure 1 As shown, the spacecraft flight program injection method provided by the embodiment of the present invention includes:
[0051] Step S1: In response to a triggering action of selecting a maintenance mode of a spacecraft flight program, calling a spacecraft flight program carried based on a preset framing strategy, and maintaining the spacecraft flight program according to the selected target maintenance mode;
[0052] The preset framing strategy is a framing strategy in which each remote control data frame carries two digital tube user injection format frames, and the maintenance mode is adapted to normal working conditions and emergency working conditions respectively.
[0053] Step S2: calling the target data injection strategy according to the monitoring result of the orbit control instruction, and injecting the flight program of the spacecraft that has completed maintenance according to the target data injection strategy.
[0054] In the above step S1, the device responds to the trigger action of selecting the maintenance mode of the spacecraft flight program, calls the spacecraft flight program carried based on the preset framing strategy, and maintains the spacecraft flight program according to the selected target maintenance mode;
[0055] The preset framing strategy is a framing strategy in which each remote control data frame carries two digital tube user injection format frames, and the maintenance mode is adapted to normal working conditions and emergency working conditions respectively. The device can be a computer device that executes the method, for example, it can include a spacecraft flight control server. It should be noted that the acquisition and analysis of data involved in the embodiments of the present invention are authorized by the user.
[0056] The spacecraft flight program is carried based on a preset framing strategy, including:
[0057] Acquire the sum of the first longest byte length of the spacecraft remote control data frame format and the frame header and frame tail byte lengths, and the second longest byte length of the data tube user injection format;
[0058] If it is determined that the difference between the first longest byte length and the sum of the frame header and frame tail byte lengths is greater than the second longest byte length and less than twice the second longest byte length, the integer part of half of the difference is used as the used byte length of the digital tube user injection format.
[0059] By eliminating the conflict between the frame requirements of the spacecraft remote control data frame format and the digital tube user injection format and appropriately shortening the maximum length of the digital tube user injection format, a framing strategy is constructed in which each remote control data frame carries two digital tube users.
[0060] Appropriately shorten the maximum length of the data tube user injection format to maximize the spacecraft remote control data frame to carry the flight program content, such as Figure 2 The specific strategies are as follows:
[0061] Assume that m is the first longest byte length of the spacecraft remote control data frame format, n is the second longest byte length of the digital tube user injection format, l is the used byte length of the digital tube user injection format, and r is the sum of the frame header and frame tail byte lengths of the spacecraft remote control data frame format. It is known that m, n, l and r are integers. If n<(mr)<2n, then take l=[(mr) / 2], that is, the integer part of (mr) / 2, so that each remote control data frame of the spacecraft carries two digital tube user injection format frames, thereby maximizing the capacity of carrying spacecraft flight programs.
[0062] The triggering action of selecting the maintenance mode of the spacecraft flight program in response to the above-mentioned operation, calling the spacecraft flight program carried by the preset framing strategy, and maintaining the spacecraft flight program according to the selected target maintenance mode, includes:
[0063] In response to a triggering action of a maintenance mode of a spacecraft flight program selected by a digital management user according to working condition information, the spacecraft flight program carried based on a preset framing strategy is called, and the spacecraft flight program is maintained according to the selected target maintenance mode;
[0064] The target maintenance mode includes one of deleting and adding, deleting first and then adding, deleting and adding in blocks at a time, and adding only without deleting. The deleting and adding corresponds to the normal working condition, and deleting first and then adding, deleting and adding in blocks at a time, and adding only without deleting all correspond to the emergency working condition. The specific description is as follows:
[0065] The "delete and add" mode means that each injected data block first deletes the old data of the specified time period, and then updates the new data of the same time period to ensure the safety of the injection implementation. This mode is selected under normal circumstances.
[0066] The "delete first, then add" mode refers to a mode in which the first injected data block deletes the old data of the specified time period, and the subsequent injected data blocks update the new data of the same time period. This mode is selected when it is necessary to delete the old data on the spacecraft first in an emergency situation.
[0067] The "one-time deletion and block addition" mode means that the first injected data block deletes the old data of all flight programs in the RAM area, and the subsequent injected data blocks update the new data for a specified time period. This mode is selected when it is necessary to delete all old data on the spacecraft in an emergency.
[0068] The "only add but not delete" mode refers to a mode in which new data in a specified time period is updated only by injecting data blocks. This mode is selected in emergency situations when it is necessary to add some instructions during a certain time period on the spacecraft without affecting the instructions on it.
[0069] In the above step S2, the device calls the target data injection strategy according to the monitoring result of the orbit control instruction, and injects the flight program of the spacecraft that has completed maintenance according to the target data injection strategy. The flight program of the spacecraft that has completed maintenance can be injected into the spacecraft flight controller, and the spacecraft flight control can be realized through the spacecraft flight controller.
[0070] The method of calling the target data injection strategy according to the monitoring result of the orbit control instruction includes:
[0071] If it is determined that the time interval between the current orbit control instruction corresponding to the current moment and the predicted next orbit control instruction is greater than or equal to the preset time interval, determining the cross-coverage injection strategy as the target data injection strategy;
[0072] The cross-coverage injection strategy is that there is a supplementary injection interval between any two adjacent injection contents. Figure 3 The specific instructions are as follows:
[0073] Under normal circumstances, that is, the above time interval is greater than or equal to the preset time interval, reflecting that the orbit control instructions implemented on the ground are relatively sparse, the flight program data injection uses a cross-coverage method. In principle, the update cycles of each flight program injection content cover several cycles after the next flight program data injection time. For example, when a spacecraft flies around the earth, each injection of the spacecraft flight program can correspond to the spacecraft flying 4-5 circles around the earth. When the spacecraft has flown 3-4 circles around the earth, the next spacecraft flight program can be injected.
[0074] This can ensure that when a data injection fails, the spacecraft flight program data will still have a certain degree of accuracy before the next data injection, and there will be sufficient measurement and control arcs to supplement the current injection before the next scheduled injection time. That is, the flight program injection content starts after leaving the current backup injection station, and at least covers the period after the next flight program injection backup station leaves the station.
[0075] The method of calling the target data injection strategy according to the monitoring result of the orbit control instruction includes:
[0076] If it is determined that the time interval between the current orbit control instruction corresponding to the current moment and the predicted next orbit control instruction is less than the preset time interval, determining the seamless connection injection strategy as the target data injection strategy;
[0077] The seamless connection injection strategy is that there is no supplementary injection interval between any two adjacent injections. The specific description is as follows:
[0078] In special circumstances, that is, the above time interval is less than the preset time interval, reflecting that the orbit control instructions implemented on the ground are relatively dense. In order to avoid injecting data of two orbit controls at the same time before one orbit control, some data injection is injected in a seamless manner.
[0079] The spacecraft flight program injection method provided by the embodiment of the present invention has the following beneficial technical effects:
[0080] 1. A method for generating spacecraft injection data and constructing injection strategies is designed.
[0081] 2. The framing requirements and conflicts between the spacecraft remote control data frame format and the digital tube user injection format were solved, and a framing strategy was constructed in which each remote control data frame carries two digital tube users, which improves the maximum carrying capacity of the spacecraft remote control data frame and increases the efficiency of flight program injection.
[0082] 3. Created four RAM area flight program maintenance modes, and solved the problem of flight program maintenance mode selection under different spacecraft working conditions.
[0083] 4. The safety issue of flight program injection has been solved, and a cross-coverage injection strategy and seamless maintenance mode for relay updates of flight programs in the RAM area have been established.
[0084] The spacecraft flight program injection method provided in the embodiment of the present invention responds to the trigger action of selecting the maintenance mode of the spacecraft flight program, calls the spacecraft flight program carried by the preset framing strategy, and maintains the spacecraft flight program according to the selected target maintenance mode; wherein the preset framing strategy is a framing strategy in which each remote control data frame carries two digital tube user injection format frames, and the maintenance mode is respectively adapted to normal working conditions and emergency working conditions; calls the target data injection strategy according to the monitoring results of the orbit control instruction, and injects the spacecraft flight program that has completed maintenance according to the target data injection strategy, which can comprehensively take into account the many aspects involved in injecting the spacecraft flight program and improve the comprehensive performance of the spacecraft flight program injection.
[0085] Further, carrying the spacecraft flight program based on a preset framing strategy includes:
[0086] Obtain the sum of the first longest byte length of the spacecraft remote control data frame format and the frame header and frame tail byte lengths, as well as the second longest byte length of the data tube user injection format; refer to the above embodiment for description and no further details will be given.
[0087] If it is determined that the difference between the first longest byte length and the sum of the frame header and frame tail byte lengths is greater than the second longest byte length and less than twice the second longest byte length, the integer part of one-half of the difference is used as the byte length used for the data pipe user injection format. The above embodiment can be referred to for explanation and will not be repeated here.
[0088] Further, the triggering action of selecting the maintenance mode of the spacecraft flight program in response to calling the spacecraft flight program carried based on the preset framing strategy, and maintaining the spacecraft flight program according to the selected target maintenance mode includes:
