Description

Technical Field

[0001] The present invention relates to the field of information processing technology, and in particular to a real-time telemetry data multivariate presentation and comparison analysis system for mass-produced satellites, which is applied to the informatization of spacecraft development process. Background Art

[0002] The satellite's downlink data includes remote sensing data and telemetry data. Remote sensing data is the original data or processed data collected by the satellite payload, and telemetry data is the data of various states and physical indicators of the satellite itself, including single-machine working mode, circuit switch status, component voltage and current, temperature, etc. Monitoring and analyzing the satellite's telemetry data is an important task during the satellite development stage and the in-orbit operation stage.

[0003] For a long time, the telemetry data presentation system used in the field of satellite development and testing can only display the telemetry data of one satellite. The system will be referred to as the single-satellite telemetry presentation system below. In the past, the development speed of satellites was slow, the total amount was small, and the development and use of each satellite were relatively independent. It was rare for a single person to monitor the telemetry data of multiple satellites at the same time, and the number of simultaneous monitoring was usually not large. However, in recent years, with the increase in the number of satellites and the increase in the proportion of mass-produced satellites, the requirements for satellite telemetry data interpretation have increased. It is common for a single person to perform routine monitoring of multiple satellites at the same time, and when multiple mass-produced satellites are tested or work together, the telemetry data of multiple satellites must be jointly monitored and compared and analyzed. For this demand, presenting the telemetry data of multiple satellites in a multi-satellite telemetry presentation system is more convenient than switching back and forth between multiple single-satellite telemetry presentation systems, and the display effect is more intuitive.

[0004] The data flow of satellite telemetry data is as follows: the satellite transmits the original telemetry microwave signal to its respective ground microwave signal processing system, which processes it into digital telemetry original code and sends it to the single-satellite telemetry data processing and distribution system, which processes it into result telemetry data and sends it to the single-satellite telemetry presentation system, which displays the telemetry data in various forms. A satellite usually runs only one ground microwave signal processing system and one single-satellite telemetry data processing and distribution system instance, and can run multiple single-satellite telemetry presentation system instances at the same time, and the single-satellite telemetry presentation system can freely select the single-satellite telemetry data processing and distribution systems of different satellites as its data source.

[0005] There are two solutions to display the telemetry data of multiple satellites in a telemetry presentation system. One is to develop a new telemetry data processing and distribution system to receive the data of the ground microwave signal processing systems of multiple satellites and send the telemetry data of multiple satellites to the telemetry presentation system through the same channel, that is, to transmit the data of multiple satellites as the data of one satellite. The telemetry presentation system only integrates the configurations of multiple satellites and distinguishes them by codes in the software; the other solution is to keep the telemetry data processing and distribution system unchanged and develop a new telemetry presentation system to enable it to simultaneously receive the data distributed by multiple telemetry data processing and distribution systems. If the first solution is adopted, multiple satellites will share the same telemetry data processing and distribution system. Technically, it is difficult to increase or decrease satellites or make some changes involving a single satellite without affecting other satellites in a telemetry data processing and distribution system. The crash or restart of the system will also spread the impact to all satellites; in terms of management, each satellite has its own person in charge. The telemetry data processing and distribution system that was originally operated by each person in charge of the satellite will be transformed into a system where all persons in charge contact a dedicated person to operate on their behalf, which reduces the timeliness of the operation and increases the communication cost. The second solution can ensure configuration flexibility, overall reliability and data integrity by running multiple instances. In terms of management, the telemetry presentation system can be used freely with almost no impact. Therefore, the second solution is more reasonable.

The method includes: obtaining satellite telemetry attribute information contained in a data viewing chart selected by a user; querying the telemetry data storage table corresponding to the satellite stored in a non-relational database according to the satellite telemetry attribute information to obtain a target satellite telemetry data table; wherein the telemetry data storage table stores the telemetry data of each satellite telemetry data packet in the form of a column family; the target satellite telemetry data table stores the target satellite telemetry data corresponding to the target attribute column in the form of a column family; and displaying the target satellite telemetry data table on the satellite telemetry display page according to the data viewing chart. This document focuses on the storage and query of telemetry data, and does not involve the multivariate presentation and comparative analysis of telemetry data from multiple satellites.

[0034] Figure 1 This is a schematic diagram of the information flow of the entire system of the present invention;

[0035] Figure 2 It is a schematic diagram of the multi-satellite telemetry presentation system architecture of the present invention. DETAILED DESCRIPTION

[0036] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0037] According to the present invention, a real-time telemetry data multi-dimensional presentation and comparison analysis system for mass-produced satellites is provided. Figure 1 and Figure 2 As shown, it includes: a front end and a back end. The front end includes a page management module and corresponding controls, and various types of controls are used to realize the multi-dimensional presentation and comparative analysis of real-time telemetry data of mass-produced satellites. Among them, the control is the smallest unit for telemetry data presentation and comparative analysis, and a single control can display telemetry data from multiple satellites. The back end is responsible for receiving and storing multi-satellite telemetry data, maintaining the latest real-time telemetry information table, and triggering all controls to update the displayed telemetry data and perform basic processing and interpretation of the telemetry data.

[0038] The backend includes a configuration information management module, an anomaly monitoring module, a telemetry receiving thread, a state change monitoring module, a telemetry storage module, a telemetry playback module, and a real-time telemetry information table; the telemetry receiving thread receives the telemetry data corresponding to each satellite to the real-time telemetry information table, and the telemetry data in the real-time telemetry information table is stored in the telemetry storage module. The historical telemetry data is transmitted to the real-time telemetry information table through the telemetry playback module, and the state change monitoring module and the anomaly monitoring module respectively monitor the data in the real-time telemetry information table and update the relevant content in real time, and finally transmit it to the front end for display. The configuration information management module is used to manage the information settings and configuration files of each satellite and the settings in the system.

[0039] The system settings of the present invention include default parameter settings of controls, voice broadcast settings, telemetry alarm settings, telemetry storage settings and software update settings. Satellite information settings include: target satellite set management, as well as key telemetry configurations of each satellite, telemetry channel configurations, telemetry data receiving addresses and ports, etc., and telemetry basic information tables. Each target satellite provides a series of configuration files to maintain various configuration information required in the software. Each target satellite has a corresponding telemetry receiving thread to receive telemetry data, and maintains a total data structure to represent the latest data of all telemetry channels of all satellites, that is, maintains a real-time telemetry information table that is updated in real time according to the received telemetry data. The telemetry storage module can simultaneously store independent data of each target satellite and mixed data of all target satellites based on time sequence. The telemetry data stored in the telemetry storage module can be played back, and the playback mode includes single satellite data playback and multi-satellite data mixed playback.

[0040] Users monitor satellite telemetry data by adding controls in the software page. The controls adopt a unified interface design and expand new data display forms by developing new types of controls. Each control obtains telemetry data from the real-time telemetry information table according to the selected satellite code and telemetry channel code. A single control can contain telemetry data of multiple satellites. The controls include table type controls, graph type controls, statistical chart type controls and graphical type controls.

[0041] The table type control includes a telemetry parameter detail table control, a multi-satellite same-name channel data comparison and analysis table control, an alarm record table control, a state change record table control, a command record control and an original code display control. The telemetry parameter detail table control is in the form of a table, and each row displays detailed information of the latest telemetry data corresponding to a telemetry code, including fixed parts such as channel name, normal value range, belonging subsystem, etc., and changing content such as processing results, status, original code, etc. The multi-satellite same-name channel data comparison and analysis table control is in the form of a table, and each row displays a telemetry code and the processing results corresponding to each satellite, and displays statistical information such as the average value, maximum and minimum values, and variance of these data. In the same series of mass-produced satellites, the telemetry code set of each satellite is similar, that is, a large number of telemetry codes will appear in each satellite in the series. It is of great value to put the same-name telemetry of all satellites together for comparison and analysis. The alarm record table control includes two tables, one of which records the details of the alarm data, including the alarm telemetry code, its normal value range, alarm value, occurrence time, etc.; the other table records the statistical information of the telemetry of each alarm, including the alarm telemetry code, its normal value range, alarm times, alarm value range, etc. Its update is triggered by abnormal detection. The state change record table control is used to record the state changes of the telemetry of interest, and a series of changes can be used as a template to compare the timing consistency of two times when doing similar projects. The header includes the telemetry code, telemetry name, change generation time, state change content, value change content, etc. Its update is triggered by state changes. The instruction record control records the code, name, sending time and execution status of each instruction. The original code display control displays the content of the latest original code in real time, and caches a part of the historical original code for professionals to perform lower-level monitoring and analysis. The original code refers to the data transmitted by the telemetry data processing and distribution system, including the original satellite telemetry data before processing.

[0042] The curve graph type controls include telemetry curve graph controls, telemetry relationship curve graph controls, and spectrum curve graph controls. The telemetry curve graph control uses time as the horizontal coordinate and the telemetry value as the vertical coordinate. Each telemetry draws a curve to reflect the value change of the telemetry of interest over a period of time. Multiple telemetry curves can be added and refreshed in real time as time changes. The telemetry relationship curve graph control uses the value of one telemetry as the horizontal coordinate and the value of another telemetry as the vertical coordinate to reflect the relationship between the two telemetry values, and then analyze the mutual influence between the satellite's on-board states. The spectrum curve graph control is connected to a spectrum analyzer on the ground to monitor the microwave waveform of important original telemetry microwave signal channels. The telemetry data processing and distribution system forwards the microwave waveform data of the spectrum analyzer, and the control is responsible for displaying it, simulating the effect of the spectrum analyzer on the system.

[0043] The statistical chart type controls include bar chart controls and radar chart controls. The horizontal axis of the bar chart control is the telemetry code and name, and the vertical axis is the telemetry value. It is mainly used to intuitively compare the high and low of the same type of telemetry, such as the same-name telemetry of batch-produced stars, telemetry of various temperatures, telemetry of various currents, etc. The radar chart control is similar to the bar chart, the main difference is that the values ​​are compared in the form of a radar chart.

[0044] The graphical type controls include graphical controls. The basic elements of graphical controls are geometric figures, the most commonly used of which are rounded rectangles. The value and status of telemetry can be displayed on the icon, and the change of its status is reflected by the change of the background color of the icon. Multiple icons can be placed in a block diagram to indicate their association, and detailed information such as their telemetry codes can be viewed by right-clicking. Compared with controls such as the telemetry parameter detail table control, this control omits information such as the original code, normal range, subsystem, and even the telemetry code and telemetry name in the presentation, and presents the most concerned content in a simple way, so that more telemetry information can be displayed on the same area, and the integration is greatly improved. At the same time, with the help of regional division, users can quickly locate the telemetry graphics of concern.

[0045] The front-end appearance of the real-time telemetry data multi-dimensional presentation and comparison analysis system of the present invention adopts a traditional design, with a menu bar on the upper side, a tool bar on the left side, a status bar on the lower side, and a page browser in the middle. The menu bar includes functions such as system settings, satellite information settings, page file management, and historical data playback. The tool bar includes functions such as adding pages, adding controls, channel selection, and monitoring. The status bar displays information such as telemetry and the status of each satellite subsystem. The page browser is the core part of the front end and is the main display carrier for multi-dimensional presentation and comparison analysis of real-time telemetry data; it performs operations such as page creation, switching, moving, and deletion in a browser-like manner, and each page is composed of several controls. The control is the smallest unit for telemetry data presentation and comparison analysis. A single control can display telemetry data from multiple satellites. Through various types of controls, multi-dimensional presentation and comparison analysis of real-time telemetry data of mass-produced satellites can be realized. The controls include table type controls, curve type controls, statistical chart type controls, etc.

[0046] Further, in terms of implementation, the operating environment of the system of the present invention is Windows operating system, the type is Windows form application, and the system setting content includes default parameter settings of expansion controls, voice broadcast settings, telemetry alarm settings, telemetry storage settings and software update settings. Satellite information settings mainly include: target satellite set management, as well as key telemetry configuration of each satellite, telemetry channel configuration, telemetry data receiving address and port, etc., and telemetry basic information table. Page file management includes saving and loading of a single page, saving and loading of a page set, etc. Historical data playback includes single-satellite telemetry data playback and multi-satellite telemetry data mixed playback. The time period can be freely selected, the speed can be adjusted, and the progress can be dragged back and forth. The channel is the interface for satellite data transmission. A satellite usually has multiple channels, and the data of each channel is the same. The design of multiple channels is for reliability and adaptation to different working conditions. The system only displays the data of one channel for each satellite at the same time, and stores the data of all channels. The channel can be switched freely by the user, and the on-off status of each channel can be monitored.

[0047] The backend creates multiple threads, each of which is responsible for receiving the telemetry data transmitted by the telemetry data processing and distribution system of the corresponding satellite, storing all of them in a file, generating a new file every once in a while, and updating the backend data according to the selected channel. The backend maintains a real-time telemetry information table to store the latest telemetry data information of all satellites. Every time each thread receives data from the channel, it triggers all controls that reference the satellite data to refresh, that is, according to the selected telemetry code, it obtains the latest data from the real-time telemetry information table and updates the control display content according to the data. Specifically, the basic processing and interpretation of telemetry by the backend includes the following:

[0048] Abnormal detection: Each telemetry has a normal value range. If it exceeds this range, it means that the satellite may be in an abnormal state and needs to be paid special attention. Therefore, the system monitors whether each telemetry is in the normal range in real time. If there is an abnormal state, the abnormal telemetry row will be highlighted in red in the telemetry parameter detail table control, and a record will be generated in the alarm record table control, and voice broadcast can be used to prompt the user to check the cause. After the abnormality is resolved, the red highlight of the corresponding telemetry disappears and the voice broadcast stops.

[0049] State change: Each telemetry usually has several states, each state represents a range of values. The telemetry data transmitted by the telemetry data processing and distribution system contains state information. The system monitors the state changes of each telemetry in real time.

[0050] The control is designed as a group of modules with the same interface. One control can create multiple instances, and one page can embed multiple control instances. New data display forms can be expanded by developing new types of controls. Each control can select the telemetry code to focus on from all satellites.

[0051] Those skilled in the art know that, in addition to realizing the system and its various devices, modules, and units provided by the present invention in a purely computer-readable program code, it is entirely possible to realize the same functions in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps.
