Description

Technical Field

[0001] The present invention relates to a spectrometer data monitoring system and method, and more particularly, to a gamma-ray spectrometer data monitoring system and method for a planetary exploration satellite, so as to collect and analyze data from a gamma-ray spectrometer of a lunar exploration satellite in real time. Background Art

[0002] Gamma-ray spectrometers are devices that measure the energy of gamma rays emitted by unknown isotopes and are widely used in the fields of nuclear energy, geochemistry, and astrophysics. In particular, gamma-ray spectroscopy is essential for planetary exploration to confirm the presence of water, etc.

[0003] Furthermore, the gamma-ray spectrometer installed on the lunar exploration satellite (KPLO, Korean Pathfinder Lunar Orbiter) collects data every 10 seconds and continuously stores the data at 100% duty.

[0004] Therefore, the amount of data stored in one day is 24×3600 / 10, which is a very large number. Since each data file includes multiple measurement data, it is very difficult to confirm whether the measurement data is normal data, classify the data collected during the specific period to be analyzed one by one, and process each data into analysis data and confirm it as needed.

[0005] Therefore, it is necessary to develop a system and method to confirm whether the gamma-ray spectrum data and other information sent from the planetary exploration satellite are normal, so that the analysis of the planetary exploration situation and the gamma-ray spectrum data can be facilitated through monitoring.

In order to describe the invention in the best way, the inventor of the present invention may appropriately define the concepts of various terms and use them. Furthermore, these terms or words should be interpreted with the meanings and concepts that are consistent with the technical ideas of the present invention.

[0051] That is, the terms used in this specification are only used to illustrate the preferred embodiments of the present invention, and are not used to specifically limit the contents of the present invention. These terms are defined after considering various possibilities of the present invention.

[0052] Furthermore, it should be understood that, in the present specification, a singular expression may include a plural expression if no other meaning is clearly indicated in the text, and even if similarly expressed in the plural, it may include the singular meaning.

[0053] Throughout this specification, when a certain component is described as “including” other components, this does not mean that any other components are excluded, and any other components may be included unless there is a description to the contrary.

[0054] Furthermore, when it is recorded that a certain structural element is "connected internally or between" other structural elements, it should be understood that the structural element can be directly connected or in contact with other structural elements, or can be separated from each other by a specified distance. In the case of being separated from each other by a specified distance, there may be a third structural element or unit for fixing or connecting the corresponding structural element to the other structural elements, and the description of the third structural element or unit may be omitted.

[0055] On the contrary, when a certain structural element is described as being “directly connected” or “directly coupled” to another structural element, it should be understood that there is no third structural element or unit.

[0056] Similarly, other expressions to describe the relationship between structural elements, namely, “between” and “just between”, or “adjacent to” and “directly adjacent to”, etc., should also be interpreted as having the same purpose.

[0060] In the drawings of this specification, in order to fully and clearly convey the concept of the present invention or for the convenience of explanation, the size, position, connection relationship, etc. of the various structural elements constituting the present invention may be partially exaggerated, reduced or omitted. Therefore, the proportion or scale may not be strict.

[0061] Furthermore, in the following description of the present invention, structures that are judged to make the gist of the present invention unnecessarily obscure may be omitted, such as detailed descriptions of known technologies including related arts.

[0062] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0063] Figure 1 FIG. 1 is a diagram showing a block structure of a gamma-ray spectrometer data monitoring system 100 for a satellite according to an embodiment of the present invention.

[0064] like Figure 1 As shown, the gamma-ray spectrometer data monitoring system 100 according to the embodiment of the present invention may include a data collection unit 110 , an environment setting unit 120 , a data processing unit 130 and a visualization unit 140 .

[0065] The data collection unit 110 may be used to collect raw data including gamma-ray spectrum data and detection environment information of the satellite 10 and the gamma-ray spectrometer from the satellite 10 having the gamma-ray spectrometer.

[0066] Gamma-ray spectrometers can be designed so that a lunar orbiting satellite's gamma-ray spectrometer (GRS), a device that measures the energy of gamma rays released by the interaction of radioactive isotopes with cosmic rays on the lunar surface, collects data about the lunar structure.

[0067] The gamma rays detected by the spectrometer can tell us about the elements present on the lunar surface, because each element emits gamma rays with a specific energy. By measuring this energy, the element can also be identified and its amount estimated.

[0068] The data collected by a gamma-ray spectrometer is usually very complex and requires sophisticated analysis. The raw data can usually be displayed in the form of an energy spectrum, that is, a graph showing the number of gamma rays detected at each energy level.

[0069] Gamma-ray spectrometers are limited in that they can only detect elements located in the upper tens of centimeters of the lunar surface. Nevertheless, the data provided by gamma-ray spectrometers could be very useful for understanding lunar geology and potential resources.

[0070] Moreover, if Figure 1 As shown, the data collection unit 110 may include: a receiving unit 111, used to receive raw data and detection environment information at preset time intervals; and a data storage unit 113, used to store the received raw data and detection environment information.

[0071] The detection environment information may include at least one of gamma-ray spectrometer information, detection satellite 10 information and gamma-ray spectrum information.

[0072] Data communication between a planetary exploration satellite 10 such as the moon and the gamma-ray spectrometer data monitoring system 100 of an embodiment of the present invention can be carried out through wireless communication of a specific frequency allocated between the satellite 10 and a ground station (Ground Station), and data can be communicated through wired communication or wireless communication between the ground station and the receiving part 111 of the gamma-ray spectrometer data monitoring system 100 of an embodiment of the present invention.

[0073] That is, the data collected from the planetary exploration satellite 10 is transmitted to the ground station via the communication system within the satellite 10, and the ground station can receive the corresponding data and transmit it to the monitoring system 100 of the embodiment of the present invention.

[0074] In addition, the communication time between the planetary exploration satellite 10 and the earth is determined by the distance and communication speed, and data sending and receiving can only be carried out during the time period when communication with the earth is possible. The receiving unit 111 can be used to receive the above-mentioned original data and detection environment information at specified time intervals or cycles.

[0075] Furthermore, the storage unit is a device for storing the received raw data and the detection environment information, and is a storage location for the raw data that has not been processed.

[0076] Moreover, if Figure 1 As shown, the environment setting unit 120 can be used to set and input the time range and display environment to be monitored. That is, the time range to be monitored can be set to start and end time in time units such as year, month, day, hour, minute, and second. When the visualization unit 140 displays the data in the form of graphics, multiple display conditions can be set to provide a structure that can set a customized monitoring environment according to user needs.

[0077] The data processing unit 130 can be used to store the structure of archived data that classifies and processes the above-mentioned original data collected according to the above-mentioned time range input by time and project, and may include: an aggregation unit 131, used to aggregate the collected data and classify it by time and project; and a file storage unit 133, used to store archived data.

[0078] In the case where the original data is energy spectrum data, the aggregation unit 131 may aggregate the data collected from at least one channel within a set time range and classify the data by time and item.

[0079] The process of summing the data collected from each channel means the process of collecting necessary information from the raw data and summing them. The raw data obtained from the gamma-ray spectrometer records the values ​​of various items in each time unit.

[0080] Processing this raw data to extract only the required information and adding the data corresponding to the time range to generate new data is the summing process.

[0081] The reason and advantage of summing the gamma-ray spectrum data of each channel are as follows.

[0082] 1) Data compression: Gamma-ray spectrometers measure and collect data at a very fast speed. Since the data of various items measured every hour may form a large volume, if the data corresponding to the time range is combined into one by summing, the data can be stored in a smaller volume than the original data.

[0083] 2) Information extraction: Since the original data may contain data on various items other than the information of interest, as long as the required information is extracted and stored through summing, only the data required for analysis or visualization can be processed.

[0084] 3) Ease of data analysis: Since the aggregated data is in a more refined form, data analysis becomes easier. The size of the data becomes smaller and only contains the required information, making the analysis work faster and more efficient.

[0085] 4) Real-time monitoring and visualization: Since summing data is generated at short intervals, it is useful to monitor and visualize the data in real time. This allows you to quickly obtain the information you need to confirm gamma ray activity in real time and respond.

[0086] 5) Ease of data management: Since the summing data is organized into a file corresponding to each time range, data management is more convenient. Storing a file at each time makes it easier to search and back up, and can better ensure the consistency and accuracy of the data.

[0087] Therefore, summing can be an important process to effectively manage raw data, extract the required information and use it for analysis and visualization.

[0088] And, if Figure 1 As shown, the file storage unit 133 can be used to store archived data of message information including file names and time range information among the classified data.

[0089] The stored file is preferably a file having a table format data structure, preferably a file having a table format data structure using CSV, a spreadsheet file, etc., in which commas or other separators are used to represent each item of each data.

[0090] Moreover, the visualization unit 140 is a structure for visualizing the above-mentioned stored archived data as graphic data, and may include: an energy spectrum display unit 141, for displaying energy spectrum data collected by multiple channels in a graphical form; and a detection environment display unit 144, for displaying detection environment information including gamma-ray spectrometer information, detection satellite 10 information and cosmic gamma-ray information in a graphical form.

[0091] In this way, by displaying the gamma-ray spectrometer data of satellite 10 as graphic data that can be intuitively confirmed at a glance through multiple channels, not only can the geological and resource information of planets such as the moon be effectively monitored, but it also has the advantage of being able to be immediately used as data for effective analysis.

[0092] The spectrum display unit 141 can display the data total results of the background-subtracted main spectrometer spectrum data and shielded spectrometer spectrum data collected by multiple channels within a set period in the form of multiple graphs.

[0093] That is, the spectrum display unit 141 can process 1) the main spectrometer spectrum data after deducting the background, 2) the shielding spectrometer spectrum data after deducting the background, 3) the main spectrometer spectrum data before deducting the background, and 4) the shielding spectrometer spectrum data before deducting the background into graphic data and visualize them among the spectrum data within the set period input through the environment setting unit 120. The spectrum data of the main spectrometer may include signal processing data under high gain (gain) and signal processing data under low gain (gain).

[0094] Moreover, if Figure 1 As shown, in the detection environment information displayed in the chart of the detection environment display unit 144, the gamma-ray spectrometer information may include the high voltage averages of the main spectrometer and the shielding spectrometer of the gamma-ray spectrometer and the internal temperature value of the gamma-ray spectrometer.

[0095] Furthermore, the satellite 10 information may include position information from the center of the planet (moon) to be detected to the satellite 10, and the cosmic gamma-ray information may include gamma-ray burst data and total gamma-ray count information.

[0096] Figure 2 It is a diagram showing the detailed flow of the gamma-ray spectrometer data monitoring method of the detection satellite 10 according to an embodiment of the present invention.

[0097] like Figure 2 As shown, the gamma-ray spectrometer data monitoring method of the detection satellite 10 of the embodiment of the present invention includes: step (a) S100, the data collection unit 110 collects raw data including gamma-ray data from the satellite 10 at a specified period; step (b) S200, inputs the time range to be monitored into the time setting unit; step (c) S300, the data processing unit 130 stores a plurality of archived data that classifies and processes the above raw data collected according to the input time range according to time and project; step (d) S400, the visualization unit 140 visualizes the archived data selected from the above stored archived data as graphic data.

[0098] Wherein, step (a) S100 may include a step of storing raw data and detection environment information collected at preset time intervals.

[0099] Furthermore, step (c) S300 may include: step (c1) S310, for the energy spectrum data in the above-mentioned original data, the aggregation unit 131 aggregates the data collected from at least one channel within the above-mentioned set time range and classifies them by time and project; and step (c2) S320, the file storage unit 133 stores the archived data of the message information including the file name and time range information in the classified data.

[0100] Hereinafter, an embodiment of applying the gamma-ray spectrometer data monitoring system 100 and method of the exploration satellite 10 according to the embodiment of the present invention to the gamma-ray data monitoring system 100 and method of the lunar exploration satellite 10 will be described in detail with reference to the accompanying drawings.

[0101] Figure 3 A diagram showing a user interface (UI) block for displaying a monitoring screen of a gamma-ray data monitoring system and method using a lunar exploration satellite 10 according to an embodiment of the present invention. Figure 4 The figure is a diagram showing an actual example of displaying a gamma-ray spectrum data monitoring screen using the gamma-ray data monitoring system 100 and method of a lunar exploration satellite according to an embodiment of the present invention.

[0102] The following gamma-ray spectrometer serves as a carrier of the lunar exploration satellite 10 for measuring gamma rays released from the lunar surface. The data measured by the gamma-ray spectrometer can be used to distinguish the elements on the lunar surface according to the gamma rays released according to the inherent energy level (keV) of the radioactive elements on the lunar surface, and can be used to formulate a lunar cosmic radiation environment map, etc.

[0103] In one example, the gamma-ray spectrometer on Danuri (KPLO) can collect lunar gamma-ray observations every 10 seconds for 24 hours in lunar orbit.

[0104] like Figure 3 As shown, the summing function of the data collected from the lunar exploration satellite 10 can be commanded to execute the data summing function by setting input in the area ① of the monitoring user interface image output by the visualization unit 140. That is, it can be executed in the environment setting unit 120 of the gamma-ray data monitoring system 100 of the exploration satellite 10 of the embodiment of the present invention.

[0105] That is, if a desired time range is input in this area, necessary information can be collected from the raw data (Raw Data) and PP data (Data) stored in advance in a predetermined path in the data storage unit 113 and organized into one file.

[0106] The information list included in the aggregated data of the gamma-ray data monitoring system 100 and method applied to the lunar exploration satellite 10 according to the embodiment of the present invention is shown in Table 1 below.

[0107] Table 1

[0108]

[0109]

[0110] The time range entered in area ① can be entered in two types: start time and end time. The units can be entered as "year, month, day, hour, minute, second".

[0111] And, only the information of the predetermined items is acquired from the original raw data (Raw Data) and PP data (Data). The corresponding information list is shown in Table 1, and the information of No. 1 to No. 13 is acquired from the raw data (Raw Data), and the information of No. 14 to No. 16 is acquired from the PP data (Data).

[0112] Furthermore, as shown in Table 1, the energy spectrum data of No. 1 to No. 6 include values ​​corresponding to the number of channels for each item, and each value is separated by ";".

[0113] The values ​​of all data included in the entered time range will be stored in a summed form. Therefore, the completed summed data (Summed Data) contains an energy spectrum for each item.

[0114] That is, except for items 1 to 6, each item includes a value, and the value is stored in the completed summary data in chronological order without any deformation. The summary data is generated by the summary unit 131 of the data processing unit 130 and stored in the file storage unit 133 as archive data such as a CSV file.

[0115] The name of the generated file and the time required will be displayed in the message box below.

[0116] Moreover, if Figure 3 As shown in the figure, the list of completed summed data can be confirmed in area ②. If you click the required file in the corresponding list, the content of the file will be displayed in the right area (area ③ and area ④) in the form of a chart. At this time, area ④ will display 6 energy spectrum data in the form of a chart, and area ③ outside it will display the remaining items in the form of a chart.

[0117] Among them, Figure 4As shown, the 6 energy spectrum data of area ④ can be displayed as 6 graphic data including 1) main spectrometer spectrum data after deducting the background of signal processing under low gain (gain), 2) main spectrometer spectrum data after deducting the background of signal processing under high gain (gain), 3) shielding spectrometer spectrum data after deducting the background, 4) main spectrometer spectrum data before deducting the background of signal processing under low gain (gain), 5) main spectrometer spectrum data before deducting the background of signal processing under high gain (gain), and 6) shielding spectrometer spectrum data before deducting the background.

[0118] Moreover, if Figure 4 As shown, in area ③, as gamma-ray spectrometer information, graph data of high voltage average values ​​of a main spectrometer and a shield spectrometer of the gamma-ray spectrometer and an internal temperature value of the gamma-ray spectrometer can be displayed as graph data.

[0119] In addition, the satellite 10 information displays in a graphical form the distance information from the center of the moon to the satellite 10 to be detected (Lunar Center-KPLO distance), the movement interval information of the orbiting satellite within a day (KGRS boresight intercept), and the angular interval from the center observed from KGRS within a day (Moon-KGRS boresight separation). As cosmic gamma-ray information, gamma-ray burst data (Gamma Burst) and gamma-ray total count information (Total count) can be displayed in a graphical form.

[0120] The boresight intercept refers to the angle between the line of sight of the satellite 10 and the position of the target object (the moon) during detection. The smaller the boresight intercept is, the more accurately the satellite 10 can perform exploration.

[0121] In addition, the boresight intercept can be determined by various factors such as the sensor performance of the satellite 10, the position of the satellite 10, the position of the target object, etc., but the better the sensor performance of the satellite 10, the closer the position of the satellite 10 is to the target object, and the closer the position of the target object is to the line of sight of the satellite 10, the smaller the boresight intercept is.

[0122] Boresight separation refers to the angle at which two objects face each other. The smaller the boresight separation, the closer the two objects are to each other.

[0123] Moreover, the boresight separation is determined by various factors such as the size of the two objects, the distance between the two objects, and the speed of the two objects. The larger the size of the two objects, the shorter the distance between the two objects, and the faster the speed of the two objects, the smaller the boresight separation.

[0124] In this way, through the displayed graph, the user can intuitively check at a glance whether the data is correctly arranged in chronological order, whether there are errors in the data, and whether special signals are captured.

[0125] Furthermore, each chart can be Figure 3 By adjusting the X-axis range and setting it in the Graph control panel, you can also expand and confirm only the required time range or the energy spectrum of the required channel. Figure 1 The environment setting unit 120 performs the function. )

[0126] The program of the gamma-ray spectrometer data monitoring system 100 and method of the satellite 10 of the above-mentioned embodiment of the present invention generates an aggregate data on a daily basis for monitoring the gamma-ray spectrometer (KGRS) data. Data can also be collected and confirmed within a shorter or longer period, thereby having the advantage of being able to be used for data research for various purposes.

[0127] Furthermore, the program of the gamma-ray spectrometer data monitoring system 100 and method for the satellite 10 according to an embodiment of the present invention can be implemented in a computer-readable recording medium as computer-readable codes. Computer programmers in the field can easily infer codes and code segments for implementing the above program.

[0128] Computer-readable recording media may include all kinds of recording devices that store data that can be read by a computer system.
