Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
Furthermore, features from different embodiments of the invention may be combined with each other, unless otherwise indicated. For example, a feature of the second embodiment may be substituted for a corresponding or functionally equivalent or similar feature of the first embodiment, and the resulting embodiments are likewise within the scope of the disclosure or recitation of the present application.
The core idea of the invention is to provide a telemetry packet data domain multiplexing method to solve the problem that the existing satellite telemetry channel has limited capability and cannot meet the increasing telemetry data downloading requirement.
In order to realize the idea, the invention provides a telemetry packet data domain multiplexing method, which comprises the following steps: the telemetering packet time-sharing multiplexing is carried out, and in each downloading period of the telemetering packet, a section of data of different types is written in circularly to achieve the capability of downloading multiple types of data by the same telemetering packet; when the telemetering packets are time-division multiplexed, the multiplexing length is selected according to the telemetering parameter length, and data are not spliced on the ground; and identifying the data type before the time-division multiplexing of the telemetering packet, and analyzing the data type by selecting a corresponding processing method on the ground according to the data type of the telemetering packet.
The embodiment provides a telemetry packet data domain multiplexing method, as shown in fig. 1, including: determining a telemetry packet multiplexing mode according to the telemetry data volume, the telemetry channel capacity and the telemetry parameter downloading period; the telemetry packet multiplexing mode comprises the following steps: and performing one or more of multiplexing on the whole telemetry packet, multiplexing the local data domain of the telemetry packet, multiplexing the time of the telemetry packet and multiplexing the telemetry parameter truncation.
Specifically, in the telemetry packet data domain multiplexing method, if the amount of the downloaded data is greater than a first threshold and the downloaded data is bursty, multiplexing the entire telemetry packet is performed, where: and a first telemetering packet is fixedly adopted, data are sequentially filled into the first telemetering packet for downloading, and after the first telemetering packet is sequentially received on the ground, the data in the packet are spliced to form a group of completed data and then are analyzed.
Furthermore, in the telemetry packet data domain multiplexing method, if the data of each first telemetry packet needs to be classified and spliced and there is no real-time downloading requirement, the starting position of each packet data is identified during downloading, the starting position comprises a data type, a data sequence number and a data domain, the ground splices the data of the same type together according to the data type, and the data domains are spliced in sequence according to the sequence of the data sequence number to form complete data.
In addition, in the telemetry packet multiplexing-based satellite telemetry data downloading method, if the telemetry packet includes non-multiplexed telemetry parameters, local data domain multiplexing of the telemetry packet is performed, wherein: the telemetry packet for local data domain multiplexing of the telemetry packet comprises a multiplexing data section; and marking the initial position of the multiplexing data segment during downloading, wherein the initial position comprises a data type, a data sequence number and a data field, splicing the data of the same type in the multiplexing data segment together according to the data type, the data sequence number and the data field of the multiplexing data segment on the ground, and sequentially splicing the data fields according to the sequence of the data sequence number to form complete data.
Specifically, in the telemetry packet multiplexing-based satellite telemetry data downloading method, the telemetry packet time division multiplexing includes: in each downloading period of the telemetry packet, a section of data of different types is written in a circulating mode, so that the capability of downloading multiple types of data by the same telemetry packet is achieved; when the telemetering packets are time-division multiplexed, the multiplexing length is selected according to the telemetering parameter length, and data are not spliced on the ground; and identifying the data type before the time-division multiplexing of the telemetering packet, and analyzing the data type by selecting a corresponding processing method on the ground according to the data type of the telemetering packet.
Further, in the telemetry packet multiplexing-based satellite telemetry data downloading method, the telemetry parameter truncation multiplexing method includes: if the data bits of the source codes of the telemetering parameters are larger than the second threshold value, the representation bits of the source codes of the telemetering parameters are shortened under the condition that the representation capability of the source codes of the telemetering parameters is not changed. If the state of a certain switch is analog quantity, the number of bits of the source code representation is 12 bits, and the state represented by the analog quantity is directly converted into the state quantity of an opening state and a closing state through the satellite computer, the switch state is represented by 1 bit. If the bit width of the operation result data is larger than the second threshold value, the data representation bit number is reduced by quantizing the operation result data into a quantized telemetering value, and then the operation result data is converted into an original result according to a quantization unit on the ground. The source code is truncated at the lower bits to reduce the number of bits of its data representation.
In the satellite telemetry data downloading method based on telemetry packet multiplexing provided by the invention, the telemetry packet multiplexing mode is determined according to the telemetry data amount, the telemetry channel capacity and the downloading period of telemetry parameters, and the telemetry packet multiplexing mode comprises one or more of multiplexing of the whole telemetry packet, multiplexing of the local data domain of the telemetry packet, multiplexing of the telemetry packet in a time-sharing mode and multiplexing of the telemetry parameters in a shortening mode, so that the reasonable satellite telemetry design is realized, the design defect of the fixed data domain of the traditional telemetry packet is overcome, and the current satellite telemetry downloading pressure is relieved.
The invention designs a telemetry packet data domain multiplexing method, which solves the problem that a large amount of telemetry information cannot be downloaded by the design of a fixed data domain of a traditional telemetry packet through the modes of multiplexing a plurality of types of data in a telemetry packet in a time-sharing manner or shortening the data bit width and the like.
Telemetry packet multiplexing may multiplex the entire telemetry packet or only a segment of the telemetry packet data domain. Since the telemetry multiplexing mechanism generally brings about the increase of the telemetry period, the specific multiplexing mode adopted depends on factors such as the telemetry data volume, the telemetry channel capability, the telemetry parameter downloading period and the like.
The telemetry design method based on telemetry packet multiplexing mainly comprises the following steps:
telemetry packet whole packet multiplexing method for large data volume downloading
If the amount of data that needs to be downloaded is large and the data is bursty, the data is not typically packetized specifically.
When the satellite is designed, a telemetry packet is fixedly adopted, data are sequentially filled into the telemetry packet for downloading when the satellite downloads, and after the telemetry packet is sequentially received by the ground, the data are spliced to form a group of completed data, and then the data are analyzed according to a corresponding algorithm, as shown in fig. 2.
If each downloaded packet data needs to be spliced in a classified mode, the initial position of each packet data is identified during downloading, the initial position comprises 3 parts of a data type, a data sequence number and a data field, and the data fields are spliced in sequence according to the splicing sequence number of the data and the data of the same type on the ground to form finished data.
The method requires that the satellite is downloaded according to the data composition sequence, the data cannot be out of order, the data cannot be lost, and otherwise, the ground cannot be spliced correctly.
Such telemetry data generally does not have real-time download requirements.
Second, local data domain multiplexing method for telemetering packet
If the telemetry packet also requires the design of non-multiplexed telemetry parameters, the local data field may be multiplexed to download telemetry data with a larger amount of data, as shown in fig. 3.
The multiplexing data segment comprises 3 parts of data type, data serial number and data field, and the data field is spliced in sequence according to the splicing serial number of the data and the data of the same type on the ground according to the identification to form complete data.
The method requires that the satellite is downloaded according to the data composition sequence, the data cannot be out of order, the data cannot be lost, and otherwise, the ground cannot be spliced correctly.
Such telemetry data generally does not have real-time download requirements.
Time-sharing multiplexing method for telemetry packets
As shown in fig. 4, in each downloading period of the telemetry packet, a segment of different types of data is written in a loop to achieve the capability of downloading multiple types of data in the same telemetry packet.
The multiplexing length is selected according to the length of the telemetering parameters during multiplexing, and the telemetering parameter time-sharing multiplexing method does not need ground splicing data.
When in multiplex design, the corresponding processing method is selected by the ground according to the telemetering type of the section for analysis processing through the telemetering type identification before the telemetering data section is taken.
Four, telemetering parameter shortening multiplexing method
The method mainly aims at specific telemetering parameters, if the telemetering parameter has more source code data bits and the telemetering packet data domain limitation can not add the telemetering parameters, the representation bit number of the source code is shortened after the parameter source code is subjected to relevant processing under the condition of not changing the representation capability of the source code.
First, if a switch state is analog, the source code representation bit number is 12 bits and cannot be added to the telemetry packet. The state represented by the analog quantity is directly converted into the state quantity of the on/off states through the satellite computer, and the switch state can be represented by 1 bit.
Secondly, if the bit width of some operation result data is large, the operation result data is quantized and converted into a quantized remote measurement value, so that the data representation bit number is reduced, and the operation result data is converted into an original result according to a quantization unit on the ground.
In addition, if the requirement of the parameter on the precision of the analysis result is not high, the low order bits of the source code can be truncated, so that the number of the representation bits is reduced.
In summary, the above embodiments have described the above embodiments in detail for different configurations of the telemetry packet data domain multiplexing method, and it goes without saying that the present invention includes but is not limited to the configurations listed in the above embodiments, and any modifications based on the configurations provided in the above embodiments are within the scope of the present invention.
