All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1, an application environment of a data processing method for a small satellite according to an embodiment of the present invention is shown, where the application environment can be used in three modes of feed information transmission, satellite measurement and control, and inter-satellite information transmission between an earth station and a communication satellite, and can meet the requirement of multilink multitask communication.
Those skilled in the art will appreciate that fig. 1 is only a schematic diagram of a communication system, and does not limit the communication system. The communication system between satellites and earth and between satellites consists of a satellite constellation system and an earth station system.
The method provided by the implementation of the present invention is described in detail below with reference to the application scenario shown in fig. 1.
Referring to fig. 2, which is a flow chart illustrating a data processing method for a small satellite according to an embodiment of the present invention, it should be noted that the present specification provides the method operation steps as described in the embodiment or the flow chart, but more or less operation steps may be included based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. In actual system or product execution, sequential execution or parallel execution (e.g., parallel processor or multi-threaded environment) may be possible according to the embodiments or methods shown in the figures. Specifically, as shown in fig. 2, the method specifically includes the following steps:
s201: and acquiring a target data object, and determining a target effective data field of the target data object.
In the embodiment of the present invention, the target data object specifically includes information such as a data type, a data size, and a data length, and the valid data field of the target data object is determined according to the specific content of the transmission data information.
S202: and determining a target virtual channel identifier corresponding to the target effective data field according to the mapping relation between the effective data field and the virtual channel identifier, and taking the target virtual channel identifier as the virtual channel identifier of the target data object.
In the embodiment of the present invention, specifically, the virtual channel identifier is generated when the signal is subjected to data encoding, and different data types are identified by different virtual channels, so as to distinguish transmission data types.
Specifically, there is a mapping relationship between the virtual channel identifier and the valid data field, and the correspondence relationship between different virtual channel identifiers and valid data fields determines the target data object to be transmitted.
S203: and determining a target data format corresponding to the target data object according to the mapping relation between the data object and a preset data format.
In the embodiment of the present invention, the data transmission format may be determined according to the relationship between the transmission data object and the preset format and according to a communication information protocol. The transmission frame of the data transmission format includes a synchronization code, a version number, a spacecraft identifier, a virtual channel identifier, a frame count, a signal field, bit stream data, and check symbols. The format of the uplink frame is shown in fig. 3:
specifically, the synchronization code of the data transmission frame is used to complete the data information frame synchronization, and ensure that the receiving end can output complete and coherent signals. The version number is used for appointing the version of the current format information, wherein the version number is 2 bits, and is fixed to be '01', which indicates that the data structure is a virtual channel protocol data unit and appoints the format information version.
Specifically, the spacecraft identifier is used to agree on a spacecraft code corresponding to the current data frame format. The size of the spacecraft identifier data bits is freely selectable according to the number of satellites, but is generally not too large. The spacecraft identifier here is 8 bits, and a maximum of 256 satellites can be characterized.
Specifically, the virtual channel identifier is used to specify the address to which the bitstream data is sent in the data frame format. The virtual channel identifier data bit size is determined according to the number of virtual channel paths and is characterized by binary numbers. The virtual channel is a plurality of parallel 'virtual' paths established on a physical channel, which enables the upper layer data streams of a plurality of users to share the same physical channel, and each virtual channel has own service requirement and service level. User data from different service types are sent to the channel by adopting a virtual channel protocol data unit with fixed length and delimited by a synchronous guide head.
Specifically, the frame count is used to agree on the number of data frames to be transmitted. The frame count is 24 bits, which are encoded sequentially for the transmission frames generated on each virtual channel, and the value range is 0-224-1, each virtual channel is counted separately. The check symbol is used for checking the correctness of the data transmission frame. The RS-check symbol is 1024 bits, has a length of 128 bytes, and adopts RS (255, 223) error correction coding with an interleaving depth of 4.
Specifically, the signal field is used to determine the status of the data frames transmitted by the satellite. For upstream data frames, the signal domain has no practical significance, and this feature is reserved for use only as a reservation. For the downlink frame data, the signal field contains a playback identifier and a fixed partition identifier.
The playback identification characterizes whether the downstream data is real-time data or playback data. If the playback identifier is characterized as real-time data, the content of the fixed partition identifier is meaningless and is only filling data. If the playback identifier representation is playback data, the fixed partition identifier content represents an address from the fixed storage of the playback data.
Specifically, the bitstream data field is used to stipulate the actual valid data content to be transmitted. The bitstream data may be either plain data or band-formatted data. When the bit stream data is in a band format, the format thereof should include at least a spacecraft identifier and a virtual channel identifier.
Here, the bitstream data field is 7088 bits, which is 886 bytes long, and if the data bits of the valid data are less than 886 bytes, the AA code is padded after the valid data until the 886 bytes of the bitstream data field are filled.
S204: and nesting the virtual channel identifier and the effective data field of the target data object according to the target data format to obtain target data format data.
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 valid data field is filled and the virtual channel identifier is identified for the target data object according to the target data format, so as to obtain the target data format data.
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: determining a task source of the target data object;
the task sources of the target data object comprise three modes of satellite measurement and control, feed and inter-satellite information transmission, and the satellite measurement and control comprises operations of satellite remote measurement and control, distance measurement and the like. The feed refers to a communication link between the earth and the satellite to complete data communication between the earth station and the satellite station. The inter-satellite information transmission refers to data information interactive transmission between satellites.
In this embodiment, the three modes can be processed by the target data format to complete the satellite multitask communication working mode.
S402: determining a data frame format of the effective data field according to the task source of the target data object;
the data frame formats of the valid data field of the target data object include a direct instruction frame format and an annotation data frame format, where the annotation data frame format may include two different formats, as shown in fig. 5a, 5b, and 5c, where fig. 5a is a schematic diagram of the direct instruction frame format provided by the embodiment of the present invention, fig. 5b is a schematic diagram of an annotation data frame format 1, and fig. 5c is a schematic diagram of an annotation data frame format 2. The format of the uplink data frame may specifically include a satellite address word, a mode word, a frame data field, and a frame CRC, and different uplink data frame formats are selected according to different execution tasks, where uplink data transmission carried by the uplink data frame format may include inter-satellite data transmission or transmission between an earth station and a satellite.
S403: processing the effective data field according to the data frame format of the effective data field to obtain a processed effective data field;
the effective data field can satisfy a measurement and control mode, and can also satisfy a feed mode and an inter-satellite information transmission mode.
S404: and performing nesting processing on the virtual channel identifier of the target data object and the processed effective data field according to the target data format to obtain target data format data.
The nesting process is to fill in the upstream data frame format with the valid data field and the virtual channel identifier. The nested valid data are nested into the bitstream data, as shown in fig. 5a, 5b, and 5c, the direct command, the annotation data 1, and the annotation data 2 may be filled into the bitstream data in the uplink data frame format as valid data in different modes, and are implemented together by the space vehicle identifier, the virtual channel identifier, and the data field. Meanwhile, other transmission frames in the uplink format are filled in corresponding positions according to corresponding data.
In another specific embodiment, as shown in fig. 6, the step of performing 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 includes:
s601: acquiring a local space identifier;
specifically, the satellite can specify the type of the satellite data and the object of data reception execution according to the spacecraft identifier and the virtual channel identifier. Similarly, in the inter-satellite information transmission, the spacecraft identifier and the virtual channel identifier in the bit stream data format can determine the code number of the target satellite for transmitting the inter-satellite information, the data type for receiving the target satellite information and the object for executing the data reception.
S602: and respectively filling the local space identifiers, the virtual channel identifiers of the target data objects and the processed effective data fields into corresponding areas in the target data format to obtain the target data format data.
The following describes a specific process of inter-satellite information forwarding in a specific embodiment as follows:
step 1. the target data object is composed according to the format shown in fig. 3 and forwarded to the satellite with the reference number 01, wherein the spacecraft identifier is filled in the identifier of the satellite with the reference number 01, and the virtual channel identifier is filled in to represent the payload channel identifier. The origin of the data transmission and the virtual channel identification of the transmitted data are determined by the identifier of the populated 01-labeled satellite and the payload channel identifier.
And 2, filling effective data into the bit stream data in the uplink data frame format, wherein the direct command, the upper note data 1 and the upper note data 2 can be filled into the bit stream data as the effective data as shown in fig. 5a, 5b and 5 c.
The satellite address word in fig. 5a, 5b, 5c is filled with a satellite address word with reference number 02, which is used to determine the target satellite object for data transmission.
In view of this, in an exemplary embodiment, the data processing method may further include, as shown in fig. 7:
s701: receiving a data object in a preset data format, wherein the preset data format comprises a virtual channel identifier of the data object;
wherein the virtual channel identifier is generated at the time of formation of the data object.
S702: determining a data type of the data object according to the virtual channel identifier of the data object;
it may be understood that the data transfer object is identified by a virtual channel identifier.
S703: determining an execution object of the data object according to the data type of the data object;
in particular, different data types are handled by different execution objects.
S704: and sending the data object to the execution object so that the execution object executes the data object.
In the above embodiment, the data object is sent to the execution object, the execution object performs a corresponding data processing manner, and in order to determine the data type of the data object, the data identified by the virtual channel is used for distinguishing. In an exemplary embodiment, before step S704, as illustrated in fig. 8, the method may further include:
judging whether the data type of the data object is a filling data type, if so, not executing the data object; if not, the data object is executed and sent to the execution object, so that the execution object executes the data object.
In an embodiment, when the execution object executes the data object, the steps of sending the data object to the execution object to enable the execution object to execute the data object are as shown in fig. 9:
s901: if the data type of the data object is a direct instruction type, verifying the data object;
specifically, if the data type is platform data or payload data, the operation is also performed.
S902: if the check is passed, decoding the data object according to a direct instruction frame format;
specifically, if the direct instruction passes the check, the data is decoded, however, if the data transmission type is the platform data or the payload data, no matter whether the data is checked correctly, the first 514 bytes of the bit stream data of the platform data are forwarded to the platform star computer, and the frame data of the 128-byte check bits divided by the payload data are forwarded to the payload.
S903: and sending the decoded data object to the execution object so that the execution object executes the data object.
In satellite communications, the uplink and downlink rates of data transmission are part of the communication system, and in the 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 transmission rate of the uplink and downlink. In one embodiment, as shown in fig. 10, includes:
s1001: acquiring bit stream data information of the target data format data;
s1002: and determining the transmission rate of the uplink and the downlink according to the bit stream data information of the target data format data.
Specifically, when bit stream data information of data transmission is relatively less, the transmitting power in the satellite communication process is the same, and in order to ensure the accuracy of data transmission and reduce the error rate of transmission information, the target data transmission is completed at a low rate.
Uplink rates currently typically do not exceed 5Mbps, mostly below 1 Mbps. The influence factors of the downlink rate are necessarily related to external factors, such as the capacity of the satellite processor and the power, besides the size of the bit stream data, and are also related to the allocation of the frequency resources by the international telecommunications union.
Correspondingly, the selection collocation manner with different transmission rates of the uplink and downlink communications can be determined according to the communication task requirements, and four free combination collocation manners are listed here, for example, as shown in fig. 11, a combination manner of uplink and downlink communication rates of a satellite is shown, the uplink and downlink can select different communication rates, the uplink and downlink communication rates can be combined arbitrarily, and there are transmission combinations of an uplink low rate and a downlink low rate, and also there are transmission combinations of an uplink high rate and a downlink high rate. Different communication rate combinations can meet the requirements of different communication tasks and communication scenes.
