请参见图2,其所示为本发明实施例的一种用于小卫星的数据处理方法的流程示意图,需要说明的是,本说明书提供了如实施例或流程图所述的方法操作步骤,但基于常规或者无创造性的劳动可以包括更多或者更少的操作步骤。实施例中列举的步骤顺序仅仅为众多步骤执行顺序中的一种方式,不代表唯一执行顺序。在实际中的系统或产品执行时,可以按照实施例或者附图所示的方法顺序执行或者并行执行(例如并行处理器或者多线程处理的环境)。具体的如图2所示,所述方法具体包括以下步骤:Please refer to FIG. 2 , which is a schematic flowchart of a data processing method for small satellites according to an embodiment of the present invention. It should be noted that this specification provides the operation steps of the method as described in the embodiment or the flowchart, But based on routine or non-creative work may include more or less operation steps. The sequence of steps enumerated in the embodiments is only one way of execution sequence of many steps, and does not represent the only execution sequence. When an actual system or product is executed, the methods shown in the embodiments or the accompanying drawings may be executed sequentially or in parallel (for example, a parallel processor or a multi-threaded processing environment). Specifically, as shown in Figure 2, the method specifically includes the following steps:
S201:获取目标数据对象,确定所述目标数据对象的目标有效数据域。S201: Acquire a target data object, and determine a target valid data field of the target data object.
在本发明实施例中,具体的,目标数据对象包括数据类型、数据大小、数据长度等信息,根据传输数据信息的具体内容,确定目标数据对象的目标数据的有效数据域。In the embodiment of the present invention, specifically, the target data object includes information such as data type, data size, and data length, and the effective data field of the target data of the target data object is determined according to the specific content of the transmitted data information.
S202:根据有效数据域与虚拟信道标识符之间的映射关系,确定目标有效数据域对应的目标虚拟信道标识符,将所述目标虚拟信道标识符作为所述目标数据对象的虚拟信道标识符。S202: Determine the target virtual channel identifier corresponding to the target valid data field according to the mapping relationship between the valid data field and the virtual channel identifier, and use the target virtual channel identifier as the virtual channel identifier of the target data object.
在本发明实施例中,具体的,虚拟信道标识在信号进行数据编码时产生,不同的数据类型由不同的虚拟信道标识,以便区分传输数据类型。In the embodiment of the present invention, specifically, the virtual channel identifier is generated when the signal performs data encoding, and different data types are identified by different virtual channels, so as to distinguish the transmission data types.
具体的,虚拟信道标识符与有效数据域之间有相对应的映射关系,不同的虚拟信道标识符与有效数据域之间的对应关系,决定了所要传输的目标数据对象。Specifically, there is a corresponding mapping relationship between the virtual channel identifier and the valid data field, and the corresponding relationship between different virtual channel identifiers and the valid data field determines the target data object to be transmitted.
S203:根据数据对象与预设数据格式之间的映射关系,确定所述目标数据对象对应的目标数据格式。S203: Determine a target data format corresponding to the target data object according to the mapping relationship between the data object and the preset data format.
在本发明实施例中,具体的,可以根据传输数据对象与所述预设格式之间的关系,并根据通信信息协议确定数据传输格式。数据传输格式的传输帧包括同步码、版本号、航天器标识符、虚拟信道标识符、帧计数、信号域、位流数据和校验符号。其上行的帧格式如图3所示:In the embodiment of the present invention, specifically, the data transmission format may be determined according to the relationship between the transmission data object and the preset format and according to the communication information protocol. The transmission frame of the data transmission format includes synchronization code, version number, spacecraft identifier, virtual channel identifier, frame count, signal field, bit stream data and check symbol. The upstream frame format is shown in Figure 3:
具体的,数据传输帧的同步码用以完成数据信息帧同步,确保接受端能输出完整连贯的信号。版本号用以约定当前格式信息的版本,在此,版本号为2位,取固定“01”,表示此数据结构是虚拟信道规约数据单元,约定格式信息版本。Specifically, the synchronization code of the data transmission frame is used to complete the synchronization of the data information frame to ensure that the receiving end can output a complete and coherent signal. The version number is used to specify the version of the current format information. Here, the version number is 2 bits, and takes a fixed "01", indicating that the data structure is a virtual channel specification data unit, and the format information version is specified.
具体的,航天器标识符用以约定当前数据帧格式对应的航天器代号。航天器标识符数据位大小根据卫星数量可自由选择,但一般不宜过大。在此航天器标识符为8位,最大可表征256颗卫星。Specifically, the spacecraft identifier is used to specify the spacecraft code corresponding to the current data frame format. The data bit size of the spacecraft identifier can be freely selected according to the number of satellites, but generally it should not be too large. The spacecraft identifier here is 8 bits, which can characterize up to 256 satellites.
具体的,虚拟信道标识符用以约定数据帧格式中位流数据的发送地址。虚拟信道标识符数据位大小根据虚拟信道路数来确定,使用二进制数进行表征。其虚拟信道是建立在一个物理信道上的多个并行的“虚拟”通路,它使多个用户的上层数据流共享同一个物理信道,而每一个虚拟信道有自己的业务需求与业务等级。将来自不同业务类型的用户数据在送上信道之前采用固定长度的虚拟信道规约数据单元,并用同步导头进行定界。Specifically, the virtual channel identifier is used to specify the sending address of the bit stream data in the data frame format. The data bit size of the virtual channel identifier is determined according to the number of virtual channels, and is represented by a binary number. Its virtual channel is a plurality of parallel "virtual" paths established on a physical channel, which enables the upper-layer data streams of multiple users to share the same physical channel, and each virtual channel has its own service requirements and service levels. Before the user data from different service types are sent to the channel, a fixed-length virtual channel specification data unit is used, and a synchronization preamble is used to delimit it.
具体的,帧计数用以约定发送的数据帧数量。该帧计数为24位,其为每个虚拟信道上产生的传输帧按顺序编码,数值范围为0~224-1,每个虚拟信道单独计数。校验符号用以对数据传输帧正确性进行校验。RS-校验符号是1024位,长度为128字节,采用交织深度为4的RS(255,223)纠错编码。Specifically, the frame count is used to specify the number of data frames to be sent. The frame count is 24 bits, which are sequentially coded for transmission frames generated on each virtual channel, and the value ranges from 0 to 2 24 -1, and each virtual channel is counted separately. The check symbol is used to check the correctness of the data transmission frame. The RS-check symbol is 1024 bits, the length is 128 bytes, and the RS (255, 223) error correction coding with the interleaving depth of 4 is adopted.
具体的,信号域用以约定卫星发送的数据帧状态。对于上行数据帧,信号域无实际意义,保留该特征仅作为预留使用。对于下行帧数据,信号域中包含回放标识和固存分区识别符。Specifically, the signal field is used to specify the state of the data frame sent by the satellite. For the uplink data frame, the signal field has no practical significance, and this feature is reserved for reserved use only. For downstream frame data, the signal field contains the playback identifier and the storage partition identifier.
回放标识表征下行数据是实时数据还是回放数据。若回放标识表征为实时数据,则固存分区识别符内容无意义,仅为填充数据。若回放标识符表征是回放数据,则固存分区识别符内容代表该回放数据来自固存的地址。The playback flag indicates whether the downstream data is real-time data or playback data. If the playback identifier is represented as real-time data, the content of the storage partition identifier is meaningless, and only fills data. If the playback identifier representation is playback data, the content of the persistent storage partition identifier represents the address from which the playback data is stored.
具体的,位流数据域用以约定发送的实际有效数据内容。位流数据可以是无格式的数据也可以是带格式的数据。当位流数据为带格式的数据时,其格式中至少应包含航天器标识符和虚拟信道标识符。Specifically, the bit stream data field is used to agree on the actual valid data content to be sent. Bit stream data can be unformatted data or formatted data. When the bit stream data is formatted data, the format should contain at least the spacecraft identifier and the virtual channel identifier.
在此,位流数据域是7088位,总长886字节,如果有效数据的数据位不足886字节,则在有效数据后填充AA码,直到填满886个字节的位流数据域。Here, the bit stream data field is 7088 bits and the total length is 886 bytes. If the data bits of the valid data are less than 886 bytes, the AA code is filled after the valid data until the bit stream data field of 886 bytes is filled.
S204:根据所述目标数据格式对所述目标数据对象的虚拟信道标识符和有效数据域进行嵌套处理,得到目标数据格式数据。S204: Perform nesting processing on the virtual channel identifier and the valid data field of the target data object according to the target data format, to obtain target data format data.
在本发明实施例中,所述目标数据对象的虚拟信道标识符和有效数据域进行嵌套处理,可以考虑按照目标数据格式,对目标数据对象进行有效数据域的填充以及虚拟信道标识符的识别,以获得目标数据格式数据。In the embodiment of the present invention, the virtual channel identifier and the valid data field of the target data object are nested, and it may be considered that the target data object is filled with valid data fields and the virtual channel identifier is identified according to the target data format. , to obtain the target data format data.
在一个具体的实施例中,如图4所示,所述根据虚拟信道标识符和有效数据域进行嵌套处理,得到目标数据格式数据的步骤,包括:In a specific embodiment, as shown in FIG. 4 , the step of performing nesting processing according to the virtual channel identifier and the valid data field to obtain the target data format data includes:
S401:确定所述目标数据对象的任务来源;S401: Determine the task source of the target data object;
其中,所述目标数据对象的任务来源包括卫星测控、馈电、星间信息传输三种模式,卫星测控包含有卫星遥测遥控、测距等操作。馈电指地球与卫星之间的通信链路,完成地球站与卫星站之间的数据通信。星间信息传输指卫星与卫星之间的数据信息交互传输。The task source of the target data object includes three modes of satellite measurement and control, power feed, and inter-satellite information transmission, and satellite measurement and control includes operations such as satellite telemetry and remote control, and ranging. Feeding refers to the communication link between the earth and the satellite to complete the data communication between the earth station and the satellite station. Inter-satellite information transmission refers to the interactive transmission of data information between satellites.
在此实施例中可通过该目标数据格式对这三种模式进行数据处理,完成卫星多任务通信工作模式。In this embodiment, data processing can be performed on these three modes through the target data format to complete the satellite multi-task communication working mode.
S402:根据所述目标数据对象的任务来源,确定所述有效数据域的数据帧格式;S402: Determine the data frame format of the valid data field according to the task source of the target data object;
目标数据对象的有效数据域的数据帧格式包括直接指令帧格式、上注数据帧格式,其中,上注数据帧格式可以包括两种不同的格式,如图5a、图5b和图5c所示,其中图5a所示为本发明实施例提供的直接指令帧格式的示意图,图5b所示为上注数据帧格式1的示意图,图5c所示为上注数据帧格式2的示意图。上注数据帧格式具体可以包括卫星地址字、方式字、帧数据域以及帧CRC,根据执行任务的不同,选择不同的上注数据帧格式,上注数据帧格式所携带的上注数据传输既可以包含星间数据传输,也可以包含地球站与卫星之间的传输。The data frame format of the effective data field of the target data object includes the direct instruction frame format and the upper note data frame format, wherein the upper note data frame format can include two different formats, as shown in Figure 5a, Figure 5b and Figure 5c, FIG. 5a is a schematic diagram of a direct command frame format provided by an embodiment of the present invention, FIG. 5b is a schematic diagram of a topline data frame format 1, and FIG. 5c is a schematic diagram of a topline data frame format 2.

在卫星通信中,数据传输的上下行速率是通信系统的一部分,在本发明实施例中,数据传输速率是由位流数据决定的,位流数据的大小决定着上下行链路的传输速率。在一个具体实施例中,如图10所示,包括:In satellite communication, the uplink and downlink rates of data transmission are part of the communication system. In this embodiment of the present invention, the data transmission rate is determined by bit stream data, and the size of the bit stream data determines the uplink and downlink transmission rates.

S1002:根据所述目标数据格式数据的位流数据信息,确定上下行链路传输速率。S1002: Determine the uplink and downlink transmission rates according to the bit stream data information of the target data format data.
具体的,数据传输的位流数据信息相对较少时,卫星通信过程中发射功率是相同的,为了确保数据传输的准确性、降低传输信息误码率,则使用低速率完成目标数据的传输。Specifically, when the bit stream data information of data transmission is relatively small, the transmission power is the same during the satellite communication process. In order to ensure the accuracy of data transmission and reduce the bit error rate of transmission information, a low rate is used to complete the transmission of target data.
上行链路速率目前通常不超过5Mbps,大部分为1Mbps以下。下行速率的影响因素除了位流数据的大小之外,还和外界因素有着必然的联系,如卫星处理器能力以及功率的大小,与此同时,还与国际电联对频率资源的分配有关。Uplink rates currently typically do not exceed 5Mbps, with most being below 1Mbps. In addition to the size of the bit stream data, the influencing factors of the downlink rate are also related to external factors, such as the capability and power of the satellite processor. At the same time, it is also related to the allocation of frequency resources by ITU.
相应的,上下行通信传输速率不同的选择搭配方式可供通信任务需求来确定,在此,列举出四种自由组合搭配,如图11所示是卫星上下行通信速率组合模式,所述上下行可选择不同的通信速率,上下通信速率可任意组合,有上行链路低速率和下行链路低速率的传输组合,也有上行链路高速率和下行链路高速率的传输组合。不同通信速率组合可以满足不同通信任务和通信场景的需求。Correspondingly, different selection and matching modes of uplink and downlink communication transmission rates can be determined by communication task requirements. Here, four free combinations are listed. Different communication rates can be selected, and the upper and lower communication rates can be combined arbitrarily. There are transmission combinations of uplink low rate and downlink low rate, and there are also transmission combinations of uplink high rate and downlink high rate. Combinations of different communication rates can meet the needs of different communication tasks and communication scenarios.
