Description
技术领域Technical Field
本发明涉及感知通信一体化以及在轨任务响应技术领域,具体地,涉及一种基于感知通信一体化的在轨实时任务响应系统及方法,同时涉及一种相应的计算机终端和计算机可读存储介质。The present invention relates to the field of perception-communication integration and on-orbit mission response technology, and in particular, to an on-orbit real-time mission response system and method based on perception-communication integration, and also to a corresponding computer terminal and computer-readable storage medium.
背景技术Background technique
为了应对太空环境复杂性,卫星技术在不断地改进和优化。传统应用中,为提升航天器的运行可靠性,当在轨运行出现软故障时,可以通过代码重新刷写恢复的可逆异常时,载荷在轨重构是保障运行稳定的重要手段;但现有的在轨重构技术,基本通过测控链路上注重构数据的方式,这种方式通常存在上注速率较低的问题。对于早期简单的单粒子翻转造成的刷写恢复问题,能够在一定程度上满足使用要求。但随着近年来任务重构的数据量、复杂度增大,测控通道上注往往需要数十轨才能完成所有重构数据上注,这对当前载荷功能升级带来了不利,不仅增加了在轨数据存储、计算等额外处理代价,而且如果出现稍微繁复的运行异常问题也不能实时重构解决。In order to cope with the complexity of the space environment, satellite technology is constantly improving and optimizing. In traditional applications, in order to improve the operational reliability of spacecraft, when soft faults occur during on-orbit operation, reversible abnormalities that can be restored by rewriting the code, on-orbit reconstruction of the payload is an important means to ensure stable operation; but the existing on-orbit reconstruction technology basically focuses on reconstructing data on the measurement and control link, which usually has the problem of low upload rate. For the early simple single-particle flip-caused refresh recovery problem, it can meet the use requirements to a certain extent. However, with the increase in the amount and complexity of mission reconstruction data in recent years, the measurement and control channel upload often requires dozens of orbits to complete the upload of all reconstructed data, which is disadvantageous to the current payload function upgrade. It not only increases the extra processing costs of on-orbit data storage and calculation, but also cannot be reconstructed and solved in real time if there are slightly complicated operational abnormalities.
另外,随着航天科技的飞速发展,更多的场景正在军民融合或多任务背景下得以实现。不仅提升了军事行动的效能,也为民用领域带来了前所未有的便利和发展机遇,未来有望出现更多在轨实时多任务响应的实践需求。In addition, with the rapid development of aerospace technology, more scenarios are being realized in the context of military-civilian integration or multi-task. This not only improves the effectiveness of military operations, but also brings unprecedented convenience and development opportunities to the civilian field. In the future, it is expected that there will be more practical needs for real-time multi-task response on orbit.
而当前的在轨重构无法满足载荷任务迭代的及时响应需求。However, the current on-orbit reconstruction cannot meet the timely response requirements of payload mission iterations.
针对上述问题,一方面,增加上注通路的方案可以部分地缓解该问题,但对于雷达卫星、探测卫星等,没有专门的用户高速通信上行链路,因而,按照这样的思路,又得需要额外增加通信载荷。另外,通过星间链路等其它通道传递载荷任务数据,这样处理一方面可能会额外增加硬件代价,另一方面必须通过综合电子分系统向载荷分系统传递载荷任务数据,而不是载荷分系统自己负责接收和判断载荷任务重构数据,这无疑增大了中间交互时间和开放接口风险。In view of the above problems, on the one hand, the solution of adding uplink channels can partially alleviate the problem, but for radar satellites, detection satellites, etc., there is no dedicated user high-speed communication uplink. Therefore, according to this idea, additional communication payloads need to be added. In addition, transmitting payload mission data through other channels such as intersatellite links may increase the hardware cost on the one hand, and on the other hand, the payload mission data must be transmitted to the payload subsystem through the integrated electronic subsystem, rather than the payload subsystem itself being responsible for receiving and judging the payload mission reconstruction data, which undoubtedly increases the intermediate interaction time and the risk of open interfaces.

Those skilled in the art can refer to the technical solution of the system to implement the step flow of the method, that is, the embodiments in the system can be understood as preferred examples of implementing the method, which will not be elaborated here.
下面结合一具体应用实例,对本发明上述实施例提供的技术方案进一步详细说明。The technical solution provided by the above embodiment of the present invention is further described in detail below in conjunction with a specific application example.
该具体应用实例中,涉及气象载荷和遥感载荷,在没有高速通信上行链路、星地馈电链路(可支持Gbps上行传输速率)或星地用户链路(可支持100Mbps上行传输速率)以及不便额外搭载通信载荷的场景下实施。This specific application example involves meteorological payloads and remote sensing payloads, and is implemented in scenarios where there is no high-speed communication uplink, satellite-to-ground feeder link (which can support an uplink transmission rate of Gbps) or satellite-to-ground user link (which can support an uplink transmission rate of 100Mbps), and where it is inconvenient to carry additional communication payloads.
地面测控站通过星地测控链路发送控制指令,切换载荷通信信道为频率驻留。频率控制模块可选驻留频点为1.6GHz,经多级滤波、低噪放、下变频后至400MHz。The ground control station sends control instructions through the satellite-to-ground control link to switch the payload communication channel to frequency dwell. The frequency control module can select a dwell frequency of 1.6 GHz, which is reduced to 400 MHz after multi-stage filtering, low noise amplification, and down-conversion.
通过星地测控链路传输载荷任务切换指令,所需数据量为32Byte,为含校验位,经过置换加密后的数据,再经帧头封装,符合测控通信协议要求的数据包。The payload task switching instruction is transmitted through the satellite-to-ground measurement and control link. The required data volume is 32Byte, which is the data packet containing the check bit, after substitution encryption, and then encapsulated by the frame header, which meets the requirements of the measurement and control communication protocol.
进一步地,采用感知通信一体化处理单元,通过跟踪扫描控制完成一体化信道切换。通过一体化信号处理模块的一体化预处理、滤波、同步,直至信号稳定锁定,同时去除扰动,解调并弱信号处理,完成对一体化信道传输的信号解析和数据提取。其中:Furthermore, the integrated processing unit of perception communication is used to complete the integrated channel switching through tracking and scanning control. Through the integrated preprocessing, filtering and synchronization of the integrated signal processing module, until the signal is stably locked, disturbances are removed, demodulation and weak signal processing are performed, and signal analysis and data extraction of the integrated channel transmission are completed. Among them:

The main steps include: integrated preprocessing, filtering, synchronization, demodulation, decoding, etc.
一体化数据重构存储模块,判决一次上传是否完成,未完成是否进入关机倒计时或出境倒计时2分钟内;如果是,则将数据存储至对应的存储区域内。重构数据包存储至对应的存储区域内后,校验检查重构数据。若校验正确,则检查比特数是否符合数据包帧数,若出现尾部多余数据,根据校验结果截位;检验正确或尾部处理完成后,保留存储结果。若出现丢帧,或校验错误,则地面站重复注入重构数据包,直至存储区域内的重构数据包的帧数正确、校验正确。The integrated data reconstruction storage module determines whether an upload is completed, and whether it will enter the shutdown countdown or exit countdown within 2 minutes if it is not completed; if so, the data is stored in the corresponding storage area. After the reconstructed data packet is stored in the corresponding storage area, the reconstructed data is checked. If the check is correct, check whether the number of bits matches the number of data packet frames. If there is excess data at the end, truncate it according to the check result; after the check is correct or the tail processing is completed, retain the storage result. If frame loss or verification error occurs, the ground station repeatedly injects the reconstructed data packet until the number of frames of the reconstructed data packet in the storage area is correct and the verification is correct.
一体化通道处理模块,其中一体化信号预处理子模块,对变化范围覆盖大动态(变化范围覆盖动态大于设定阈值)、信号灵敏度低于噪声基底下限15db(信号灵敏度低于噪声基底下限)的信号进行分级、平滑、反馈等多步预处理,确保适应于感知探测信号(如雷达信号)功率范围内的通信信号,正确解调译码;扇扫驻留频率控制子模块,用于切换载荷通信信道为频率驻留模式。The integrated channel processing module, including the integrated signal preprocessing submodule, performs multi-step preprocessing such as grading, smoothing, and feedback on signals with a large dynamic range (the dynamic range covered by the variation range is greater than the set threshold) and a signal sensitivity lower than the lower limit of the noise floor by 15db (the signal sensitivity is lower than the lower limit of the noise floor), to ensure that the communication signals within the power range of the perception detection signals (such as radar signals) are adapted and correctly demodulated and decoded; the fan-scanning dwell frequency control submodule is used to switch the payload communication channel to the frequency dwell mode.
采用数字单机重构控制单元,对感知通信一体化处理单元传输的比特数据校验、组包解析,以及将验证可靠的重构指令分发至载荷单机配置单元,用于载荷单机配置单元完成载荷任务重构。A digital stand-alone reconstruction control unit is used to verify and parse the bit data transmitted by the perception and communication integrated processing unit, and distribute the verified reliable reconstruction instructions to the payload stand-alone configuration unit, so that the payload stand-alone configuration unit can complete the payload task reconstruction.
采用载荷单机配置单元,根据综合处理单元的任务切换指令,启动感知通信一体化处理单元,切换隐蔽通信高速通道,接收重构数据上传,将重构数据送达数字单机重构控制单元。A payload stand-alone configuration unit is used to start the perception and communication integrated processing unit according to the task switching instruction of the comprehensive processing unit, switch the covert communication high-speed channel, receive the reconstructed data upload, and send the reconstructed data to the digital stand-alone reconstruction control unit.
采用综合处理单元,接收测控通道上注的任务切换短指令。An integrated processing unit is used to receive short task switching instructions injected into the measurement and control channel.
综合处理单元,通过星地测控链路传输载荷任务切换指令,直接传输到综合电子模块。经综合电子模块判决后,下发指令到载荷管理单元,进行天线模式切换,扇扫方向锁定,驻留频点,完成信道转换。The integrated processing unit transmits the load task switching command through the satellite-to-ground measurement and control link and directly transmits it to the integrated electronic module. After the integrated electronic module makes a judgment, it sends the command to the load management unit to switch the antenna mode, lock the fan scanning direction, stay at the frequency point, and complete the channel conversion.
通过实施上述具体应用实例可知,在具备宽频带的脉冲信号特征的上行信道中传输通信信号,建立隐蔽通信信道,以Mbps的上行传输速率,2.4s~10min内完成载荷任务重构数据上注(根据任务量及载荷存储数据大小)。相较于传统的通过测控链路(2kbps),上注一次需要30多轨,即使以1.5h重访的近地轨道卫星,也至少需要2天时间。本发明上述实施例可应用于在轨任务重构、隐蔽通信等多种场景,可有效提升载荷快速响应、灵活任务切换的能力。Through the implementation of the above specific application examples, it can be known that by transmitting communication signals in an uplink channel with wide-band pulse signal characteristics, a covert communication channel is established, and at an uplink transmission rate of Mbps, the payload task reconstruction data can be uploaded within 2.4s~10min (depending on the task amount and the size of the payload storage data). Compared with the traditional measurement and control link (2kbps), more than 30 orbits are required for one upload, and even if the low-Earth orbit satellite is revisited at 1.5h, it will take at least 2 days. The above embodiments of the present invention can be applied to various scenarios such as on-orbit mission reconstruction and covert communication, and can effectively improve the payload's ability to respond quickly and flexibly switch tasks.

本发明上述实施例提供的基于感知通信一体化的在轨实时任务响应系统及方法,在没有高速通信上行链路,星地馈电链路(可支持Gbps上行传输速率),或星地用户链路(可支持100Mbps上行传输速率),以及不便额外搭载通信载荷的场景,能够起到较为明显的作用。同时,该系统还将对载荷任务的切换或重构任务直接放在有效载荷内自主完成,更高效更安全。 对于气象卫星、遥感卫星、探测卫星等的载荷都适用。该系统可适应电子侦察、电子干扰、主动探测和双向通信等多种频点多种使用要求的工作模式,是当前航天发展最前沿的通导遥一体化星座建设中必备且基础的创新技术。The on-orbit real-time task response system and method based on perception and communication integration provided by the above-mentioned embodiments of the present invention can play a more obvious role in scenarios where there is no high-speed communication uplink, satellite-to-ground feeder link (supporting Gbps uplink transmission rate), or satellite-to-ground user link (supporting 100Mbps uplink transmission rate), and it is inconvenient to carry additional communication payloads. At the same time, the system also places the switching or reconstruction tasks of the payload tasks directly in the payload and completes them autonomously, which is more efficient and safer. It is applicable to payloads of meteorological satellites, remote sensing satellites, detection satellites, etc. The system can adapt to working modes with multiple frequencies and multiple usage requirements such as electronic reconnaissance, electronic interference, active detection and two-way communication. It is an essential and basic innovative technology in the construction of integrated communication, navigation and remote sensing constellations at the forefront of current aerospace development.
