Before describing the satellite telemetry data processing method provided by the application, the background content related to the application is first described.
In the prior art, the related management systems behind each satellite product have respective design characteristics, and although the related management systems can meet respective space mission requirements, when a large number of management systems are managed from the whole layer, the problems of complexity and low efficiency in data processing are presented for multi-source satellite telemetry data,
Accordingly, the present application provides a method, a system, and a computer readable storage medium for processing satellite telemetry data, which provides a satellite telemetry data processing architecture, and achieves an efficient and high-precision satellite telemetry data processing effect through an automatic distributed processing scheme thereof, so as to solve the above-mentioned problems of the prior art when facing the development demands of high speed and high quality in the current aerospace industry.
Next, the satellite telemetry data processing method provided by the application will be described.
Referring initially to FIG. 1, a system architecture diagram of a satellite telemetry data processing system of the present application is shown in FIG. 1. It can be seen that the present application relates to a parallel processing architecture, and in particular, the satellite telemetry data processing system includes a plurality of ground measurement and control stations (e.g., ground measurement and control station 1 … at the top of FIG. 1, ground measurement and control station N), a plurality of ground gateway stations (e.g., ground gateway station 1 … at the bottom of FIG. 1), a telemetry data processing system (e.g., satellite health at the right of FIG. 1), and a display system (e.g., system architecture at the middle of FIG. 1).
With continued reference to fig. 2, fig. 2 shows a schematic flow chart of the satellite telemetry data processing method according to the present application, based on the system architecture diagram of the satellite telemetry data processing system according to the present application shown in fig. 1, the satellite telemetry data processing method according to the present application may specifically include steps S101 to S104 as follows:
step S101, a ground measurement and control station receives real-time telemetry data and transmits the real-time telemetry data to a telemetry data processing system, wherein the real-time telemetry data is satellite telemetry data which is downloaded to a corresponding ground measurement and control station by a first satellite in real time based on a PCM telemetry channel;
it will be appreciated that satellite telemetry (including real-time telemetry and time-lapse telemetry herein below) is the most important data volume set reflecting the operation status of each system and stand-alone unit of the satellite, and its specific data content and data format are adaptively adjusted according to the specific conditions of the relevant devices on the satellite and the data acquisition tasks, so that in practical situations, there are characteristics of more data types.
As one example, satellite telemetry data includes various types of discrete, continuous data, both analog and digital, of voltage, current, power, temperature, angle, count, status words, error identification, and the like.
For the ground measurement and control station in the satellite telemetry data processing system, the ground measurement and control station is used for communicating with a satellite and receiving satellite telemetry data (recorded as real-time telemetry data) issued by the satellite in real time based on a PCM telemetry channel.
Wherein PCM, pulse Code Modulation, pulse code modulation.
After the data receiving task is completed, the real-time telemetry data can be sent to a telemetry data processing system for centralized processing.
Real-time telemetry data is typically landed by the measurement and control channel.
It should be noted that, as shown in fig. 1, the number of the ground measurement and control stations in the satellite telemetry data processing system of the application is N (the specific number is adjusted according to the actual situation), so that in the same time, a situation that only one ground measurement and control station transmits one set of real-time telemetry data to the telemetry data processing system may occur, or a situation that a plurality of ground measurement and control stations respectively transmit one or more sets of real-time telemetry data to the telemetry data processing system may occur, which corresponds to the actual processing requirement of the satellite telemetry data of the parallel processing architecture.
Each ground measurement and control station can be mutually independent or can cooperatively work for acquiring real-time telemetry data and transmitting the real-time telemetry data, and can be adjusted according to actual conditions.
Step S102, a ground gateway station receives delay telemetry data and transmits the delay telemetry data to a telemetry data processing system, wherein the delay telemetry data is historical satellite telemetry data which is generated according to fixed frequency and downloaded to a corresponding ground gateway station in the process of running a second satellite in orbit;
the data content of the time delay telemetry data is basically the same as that of the real-time telemetry data, and the difference is that the time effectiveness of the data is different, and the data acquisition time point of the time delay telemetry data is obviously behind that of the real-time telemetry data, so that the satellite telemetry data is distinguished by real-time and time delay.
Corresponding to the real-time and time-delay characteristics, the specific data transmission link and communication link can be correspondingly adjusted in the process of transmitting the data from the overhead satellite to the ground station, and it is understood that the application is not further described in the prior art.
The delayed telemetry data is typically landed by the traffic channel.
Unlike ground measurement and control station, the ground gateway station in the satellite telemetry data processing system is specially used for receiving the delayed telemetry data issued by the astronomical satellite, and the delayed telemetry data is generated according to fixed frequency (preset frequency, adjustable) in the satellite orbit operation process.
The delay telemetry data can be divided into the intrinsic delay telemetry data directly issued by the tracked target satellite and the other two types of data issued by the tracked target satellite through the transmission of the inter-satellite link.
And the ground gateway station receives the delayed telemetry data and then transmits the real-time telemetry data to a telemetry data processing system for centralized processing.
It should be noted that, as shown in fig. 1, the number of the ground gateway stations in the satellite telemetry data processing system of the present application is N (the specific number is adjusted according to the actual situation), so that, in the same time, a situation may occur in which only one ground gateway station transmits a set of delayed telemetry data to the telemetry data processing system, or a situation may occur in which a plurality of ground gateway stations respectively transmit one or more sets of delayed telemetry data to the telemetry data processing system, which corresponds to the actual processing requirement of satellite telemetry data of a parallel processing architecture.
Each ground gateway station can be mutually independent or can be cooperated to work for acquiring delay telemetry data and transmitting the delay telemetry data, and the adjustment can be carried out according to actual conditions.
Furthermore, it should be understood that there is no timing limitation between step S101 and step S102, and the first satellite and the second satellite in the steps are merely for distinguishing different steps, and are not limited to one satellite being unable to download real-time telemetry data and delay telemetry data at the same time, or the first satellite and the second satellite may be directed to the same satellite.
Step S103, the telemetry data processing system analyzes and processes multi-source telemetry data in parallel based on a plurality of telemetry data processing nodes and protocols of preconfigured telemetry data of different types, wherein the multi-source telemetry data is satellite telemetry data from different telemetry data sources, and the multi-source telemetry data comprises real-time telemetry data and satellite telemetry data of delay telemetry data;
after the telemetry data processing system acquires a plurality of satellite telemetry data from the ground station (comprising the ground measurement and control station and the ground gateway station), the telemetry data processing system can automatically store the satellite telemetry data and also can analyze and process the corresponding telemetry data so as to realize monitoring response on the aspects of real-time monitoring of satellite health status, satellite fault diagnosis, on-orbit fault treatment and the like, and promote good operation of satellite on-orbit work.
Among other things, for the numerous satellite telemetry data mentioned herein (including real-time telemetry data and time-lapse telemetry data), it should be understood that the various satellite telemetry data processed by the telemetry data processing system are satellite telemetry data from different telemetry data sources, whereas in contrast to the prior art where each type of data source (corresponding to a satellite-related equipment product or data transfer node such as a ground station) is configured with a telemetry data parsing tool, the present application provides centralized parallel processing by the telemetry data processing system, thereby simplifying the processing architecture and optimizing the processing results.
