Abstract

The present invention provides a method and system for autonomous control of a satellite-borne data transmission link based on preset logic, which relates to a satellite-borne data transmission link and includes: step S1: selecting a channel combination after searching a parameter table in the satellite-borne software based on the data transmission set in a work package sent from the ground; step S2: autonomously determining the power-on and power-off instructions and time for each single machine based on the channel determined by the data transmission parameters; step S3: judging the relay parameter setting value in the work package; if it is set to relay, repeating steps S1 to S2 to generate subsequent instructions; if it is set to non-relay, directly proceeding to generate subsequent instructions. Since the present invention pre-stores all possible working data transmission link modes and corresponding radio frequency channel combination tables and product control instructions, when it is necessary to switch the data transmission link mode, only the ground needs to send a reorganized link catalog number to achieve autonomous control link switching, thereby realizing autonomous control of the satellite-borne data transmission link.

Description

Technical Field

[0001] The present invention relates to the technical field of satellite-borne data transmission links, and in particular to a method and system for autonomous control of a satellite-borne data transmission link based on preset logic, and in particular to an autonomous control method for a satellite-borne data transmission link based on preset logic that has been verified by in-orbit flight. Background Art

[0002] In order to achieve comprehensive planning and autonomous control of complex satellite missions, an on-board autonomous control method for satellite-borne data transmission links is needed that can significantly reduce the number of work package parameters generated on the ground and reduce the difficulty of ground control.

[0003] Traditional methods for controlling satellite-borne data transmission links are generally divided into direct ground-based remote control and onboard program control. Direct ground-based remote control is complex and error-prone, while onboard program control relies on preset command templates, supports limited modes, and requires system reconfiguration via program injection in the event of a failure.

[0004] Patent document CN115173929A discloses a satellite-to-ground high-speed data dual-station relay transmission test method and system, including: compiling a dual-station relay betting package; uploading the dual-station relay betting package; real-time telemetry monitoring of the betting package execution and transmission system startup status, and checking whether the ground equipment is receiving data from the front station; real-time telemetry monitoring of the switching process of the antenna where the satellite data transmission channel is located; real-time telemetry monitoring of the transmission system operation and shutdown status, and checking whether the ground equipment is receiving data from the back station; locating the AOS format digital transmission data frame count of the last frame of data for each channel in the front station data; locating the AOS format digital transmission data frame count of the first frame of data for each channel in the back station data. If the frame count of the first frame of each channel of the back station is continuous with the frame count of the last frame of each channel of the corresponding front station, it is determined that the data relay transmission between the two stations is normal. This invention is applicable to both ground testing and on-orbit testing, ensuring the validity and comparability of test data. However, the patent does not involve on-board data transmission link control methods.

[0005] Patent document CN113890590A discloses a satellite-borne data transmission transmitter, system, and intelligent terminal, including a power module, baseband module, radio frequency module, and interface module. By optimizing the circuit connections between modules and reducing the number of input and output pins occupied by the circuits, the wiring space requirements of the satellite-borne data transmission system are reduced. By changing the chips within each module, the module footprint is reduced, meeting the satellite's requirements for a small size, large capacity, and high downlink bit rate for a data transmission transmitter. Compared to conventional data transmission subsystems in the prior art, this system occupies less space and can meet the space requirements for satellite-borne data transmission links. However, this patent does not cover methods for controlling satellite-borne data transmission links.

[0006] Patent document CN113608720A discloses a single-event upset-resistant onboard data processing system and method, comprising a DSP processor, an FPGA (Field Programmable Gate Array), a Flash memory, a readback and refresh chip, a PROM memory, and an external interface driver module. The DSP processor is connected to the FPGA, the Flash memory is connected to the DSP processor and the FPGA via data and address buses, respectively. The FPGA is connected to the readback and refresh chip, which is then connected to the PROM memory. A heartbeat line is provided between the DSP processor and the FPGA. The present invention can effectively improve development efficiency, enhance onboard data processing capabilities, reduce costs, and shorten development cycles. It can be applied to space electronic equipment such as onboard telemetry equipment, onboard remote control equipment, onboard data transmission equipment, space station voice equipment, and space station imaging equipment. However, the patent does not cover onboard data transmission link control methods.

[0011] Step S2: autonomously determine the power on / off instructions and time of each stand-alone device according to the channel determined by the data transmission parameters;

[0012] Step S3: Determine the relay parameter setting value in the work package. If it is set to relay, repeat steps S1 to S2 to generate subsequent instructions; if it is set to not relay, directly proceed to generate subsequent instructions.

[0013] Preferably, in step S1, the onboard software pre-stores a data transmission link radio frequency channel parameter combination table, including: channel parameters, antenna parameters, modulation transmitter parameters, microwave switch parameters, solid-state amplifier parameters, and waveguide switch parameters;

[0014] The channel includes six typical modes of data transmission links with autonomous control, namely single-channel left-hand antenna 1 mode, single-channel left-hand antenna 2 mode, single-channel right-hand antenna 1 mode, single-channel right-hand antenna 2 mode, dual-channel antenna 1 mode, and dual-channel antenna 2 mode;

[0015] Among them, the ground stores the link combination modes that can be reassembled in the onboard software in advance and catalogs all the modes. When necessary, the ground can switch the link combination mode by sending the catalog number corresponding to the desired reassembly mode.

[0017] Preferably, in step S3, the subsequent instructions include: starting the operation of a modulation transmitter, a microwave switch, a solid-state amplifier and a waveguide switch related to the data transmission link.

[0018] Preferably, in step S3, relay means that the satellite successively establishes data transmission links with two ground data receiving stations, and transmits the satellite remote sensing data through the two stations.

[0019] The present invention also provides an autonomous control system for a satellite-borne data transmission link based on preset logic, comprising:

[0022] Module M3: Determine the relay parameter setting value in the work package. If it is set to relay, repeatedly execute modules M1 to M2 to generate subsequent instructions; if it is set to non-relay, directly proceed to generate subsequent instructions.

[0023] Preferably, in the module M1, the satellite-borne software pre-stores a data transmission link radio frequency channel parameter combination table, including: channel parameters, antenna parameters, modulation transmitter parameters, microwave switch parameters, solid-state amplifier parameters, and waveguide switch parameters;

[0024] The channel includes six typical modes of data transmission links with autonomous control, namely single-channel left-hand antenna 1 mode, single-channel left-hand antenna 2 mode, single-channel right-hand antenna 1 mode, single-channel right-hand antenna 2 mode, dual-channel antenna 1 mode, and dual-channel antenna 2 mode;

[0025] Among them, the ground stores the link combination modes that can be reassembled in the onboard software in advance and catalogs all the modes. When necessary, the ground can switch the link combination mode by sending the catalog number corresponding to the desired reassembly mode.

[0026] Preferably, in the module M2, the onboard software pre-stores all switch setting instructions and instruction sending timings for controlling the operation of the modulated transmitter, microwave switch, solid-state amplifier, and waveguide switch, and sends instructions to the corresponding products according to the pre-stored timings as needed.

[0027] Preferably, in the module M3, the subsequent instructions include: starting the operation of the modulation transmitter, microwave switch, solid-state amplifier and waveguide switch related to the data transmission link.

[0028] Preferably, in the module M3, relay means that the satellite successively establishes data transmission links with two ground data receiving stations, and transmits the satellite remote sensing data through the two stations.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention pre-stores all possible data transmission link modes and corresponding RF channel combination tables and product control instructions. When switching data transmission link modes, only the ground needs to send the reorganized link catalog number to achieve autonomous link switching. There is no need to re-set the switching instructions and timing relationships of the specific products involved in the new data transmission link, thus achieving autonomous control of the onboard data transmission link.

[0071] As the instruction manual Figure 3 The preset parameter instructions shown in can be used by the onboard software to determine the corresponding product of the current link and issue the corresponding instructions.

[0072] The present invention also provides an autonomous control system for a satellite-borne data transmission link based on preset logic. The autonomous control system for a satellite-borne data transmission link based on preset logic can be implemented by executing the process steps of the autonomous control method for a satellite-borne data transmission link based on preset logic. That is, those skilled in the art can understand the autonomous control method for a satellite-borne data transmission link based on preset logic as a preferred implementation of the autonomous control system for a satellite-borne data transmission link based on preset logic.

[0073] An autonomous control system for a satellite-borne data transmission link based on preset logic comprises: module S1: selecting a channel combination after searching a parameter table in satellite-borne software based on the data transmission set in a work package sent from the ground; module S2: autonomously determining the power-on and power-off instructions and times for each single machine based on the channel determined by the data transmission parameters; module S3: determining whether to relay.

[0080] Since the present invention pre-stores all possible working data transmission link modes and corresponding radio frequency channel combination tables and product control instructions, when it is necessary to switch the data transmission link mode, it is only necessary to send the reorganized link catalog number from the ground to achieve autonomous control link switching, thereby realizing autonomous control of the satellite-borne data transmission link.
