Description

Technical Field

[0001] This application relates to the field of satellite management, and in particular to a method, system, apparatus and storage medium for controlling a heater using a monitoring temperature measurement point. Background Technology

[0002] Publication number CN112181023A discloses a highly reliable autonomous temperature control method for consistent temperature across different regions. The method includes the following steps: a differential temperature control enable state judgment step, a terminal temperature acquisition step, a comparison step between the terminal temperature and a set maximum threshold, a comparison step between the terminal temperature and a set minimum threshold, a differential temperature threshold judgment step, a heating circuit driving step, and a fixed delay step. This invention dynamically acquires and thermally controls the satellite terminal temperature by cyclically executing the above steps, ensuring that the temperature deviation of the terminal temperature remains within the allowable range, thus achieving high-precision differential temperature control.

[0003] Publication number CN110171584A discloses a method for mass-producing satellite constellation systems for vacuum thermal testing. Multiple satellites are simultaneously placed in a space environment simulation device, with thermal equilibrium satellites and thermal vacuum satellites selected respectively. The thermal equilibrium satellites have more severe thermal control conditions than the thermal vacuum satellites. Thermal equilibrium tests are conducted on the thermal equilibrium satellites. During the thermal equilibrium test, the equipment on the thermal equilibrium satellites is powered on according to the predetermined on-orbit operating mode, and external heat flow design parameters are applied to each surface of the thermal equilibrium satellites. The impact of mutual obstruction between satellites on the external heat flow of the thermal equilibrium satellites is simulated, and the external heat flow of the thermal equilibrium satellites is corrected in real time. During the thermal equilibrium test, the equipment on the thermal vacuum satellites is powered on according to the predetermined on-orbit operating mode, but no external heat flow is applied. After the thermal equilibrium test is completed, the high and low temperature ranges for thermal vacuum testing of the satellite system are determined based on the thermal equilibrium test results, and thermal vacuum testing of the participating satellite systems is then conducted.

[0004] For satellite systems, multiple devices within the system need to operate in a relatively suitable temperature environment; that is, the internal ambient temperature of the satellite system needs to be strictly controlled. Therefore, heaters are installed in the thermal control management system to control the operating ambient temperature.

[0005] In addition, temperature measurement points are set up within the satellite system, each equipped with a thermal sensor for measuring temperature. The thermal control management system within the satellite system can read the temperature values ​​from these measurement points and compare them with preset temperature thresholds to control the heaters to turn on or off.

[0006] Figure 1 A graph showing the temperature value measured at the measurement point by a prior art thermal sensor as a function of time is shown. (Reference) Figure 1 As shown, first in tAt time 0, the processor module sends an "on" command to the switch module and supplies power to the heater, causing the temperature at the measuring point to rise over time. t At time 1, the temperature continues to rise until it reaches the maximum temperature threshold (i.e., the temperature value). Tth 1). Then t At time 1, the processor module sends a "disconnect" command to the switch module and cuts off the power supply to the heater. The temperature at the measuring point then begins to drop, thus... t At time 2, the temperature continued to drop until it reached the minimum temperature threshold (i.e., the temperature value). Tth 2). Then t At time 2, the processor module sends an "on" command to the switch module and supplies power to the heater, causing the temperature at the measuring point to rise over time. t At time 3, the temperature continues to rise until it reaches the maximum temperature threshold (i.e., the temperature value). Tth 1). Then t At time 3, the processor module sends a "disconnect" command to the switch module and cuts off the power supply to the heater. The temperature at the measuring point then begins to drop, thus... t At time 4, the temperature continued to drop until it reached the minimum temperature threshold (i.e., the temperature value). Tth 2). This process is repeated until the temperature at the measuring point reaches the maximum temperature threshold ( Tth 1) and minimum temperature threshold ( Tth 2) Between them, around the target temperature Tref oscillation.

[0007] In this way, the thermal control management system controls the temperature at the temperature measurement point to the maximum temperature threshold within the temperature threshold range. Tth 1) and minimum temperature threshold ( Tth 2) Between.

[0008] However, since the thermal control management system controls the heater based on the temperature of the temperature measuring point, if the thermal sensor at the temperature measuring point malfunctions, the incorrect temperature value measured by the thermal sensor will cause the thermal control management system to be unable to accurately control the heater, and thus unable to accurately control the working environment temperature.

[0009] There is currently no effective solution to the technical problem in the existing technology where malfunctions of the thermal sensor at the temperature measurement point can lead to the thermal control management system being unable to accurately control the heater, and thus unable to accurately control the working environment temperature. Summary of the Invention

[0010] The embodiments of this disclosure provide a method, system, apparatus, and storage medium for controlling a heater using a monitored temperature measurement point, to at least solve the technical problem in the prior art where an abnormality in the thermal sensor at the temperature measurement point leads to the thermal control management system being unable to accurately control the heater, thereby failing to accurately control the working environment temperature.

[0011] According to one aspect of the present disclosure, a method for controlling a heater using a monitoring temperature point is provided, applied to a thermal control management system, comprising: determining a first monitoring temperature point from a plurality of temperature points set on a satellite system for controlling the heater of the thermal control management system; reading the temperature value of the first monitoring temperature point; comparing the temperature value of the first monitoring temperature point with a preset temperature threshold, wherein the temperature threshold is used to indicate the maximum and minimum temperature values ​​that the first monitoring temperature point is allowed to reach; and turning the heater in the thermal control management system on or off according to the comparison result.

[0012] According to another aspect of the embodiments of this disclosure, a system for controlling a heater using a monitoring temperature measurement point is also provided, applied to a thermal control management system. The thermal control management system includes a processor, a heater, and a thermal sensor, wherein the processor is connected to the heater and the thermal sensor, and includes: the processor determining a first monitoring temperature measurement point among a plurality of temperature measurement points set on a satellite system, and controlling the heater of the thermal control management system; the processor reading the temperature value of the first monitoring temperature measurement point measured by the thermal sensor; the processor comparing the temperature value of the first monitoring temperature measurement point with a preset temperature threshold, wherein the temperature threshold is used to indicate the maximum and minimum temperature values ​​that the first monitoring temperature measurement point is allowed to reach; and the processor turning the heater in the thermal control management system on or off according to the comparison result.

[0013] According to another aspect of the present disclosure, a storage medium is also provided, the storage medium including a stored program, wherein, when the program is executed, a processor performs any of the methods described above.

[0014] According to another aspect of the present disclosure, an apparatus for controlling a heater using a monitoring temperature point is also provided, applied to a thermal control management system, comprising: a first monitoring temperature point determination module, configured to determine a first monitoring temperature point from a plurality of temperature points set on a satellite system, for controlling the heater of the thermal control management system; a temperature value reading module, configured to read the temperature value of the first monitoring temperature point; a temperature value comparison module, configured to compare the temperature value of the first monitoring temperature point with a preset temperature threshold, wherein the temperature threshold is used to indicate the maximum and minimum temperature values ​​that the first monitoring temperature point is allowed to reach; and a control module, configured to turn the heater in the thermal control management system on or off according to the comparison result.

[0015] According to another aspect of the present disclosure, an apparatus for controlling a heater using a monitoring temperature point is also provided, applied to a thermal control management system, comprising: a processor; and a memory connected to the processor, for providing the processor with instructions to perform the following processing steps: determining a first monitoring temperature point from a plurality of temperature points set on a satellite system for controlling the heater of the thermal control management system; reading the temperature value of the first monitoring temperature point; comparing the temperature value of the first monitoring temperature point with a preset temperature threshold, wherein the temperature threshold is used to indicate the maximum and minimum temperature values ​​that the first monitoring temperature point is allowed to reach; and turning the heater in the thermal control management system on or off according to the comparison result.

[0016] In the technical solution disclosed herein, firstly, the processor module determines a first monitoring temperature measurement point set on the satellite system. This first monitoring temperature measurement point is configured to be monitored by the processor module at different times and compared with a temperature threshold. Then, the processor module reads the temperature value of the first monitoring temperature measurement point measured by a thermal sensor. Furthermore, the processor module compares the received temperature value of the first monitoring temperature measurement point with a preset temperature threshold. Finally, based on the comparison result, the processor controls the heater to disconnect.

[0017] In the embodiments of this disclosure, the processor module pre-selects a first monitoring temperature point for monitoring at different times and comparing it with a temperature threshold, and compares the temperature value of the first monitoring temperature point measured by the thermal sensor with the preset temperature threshold. Therefore, the processor module does not need to read the temperature values ​​of multiple temperature points, but selects a first monitoring temperature point with a more accurate measurement result, compares the read temperature value of the first monitoring temperature point with the preset temperature threshold, and can obtain a comparison result, thereby controlling the heater to turn on or off based on the comparison result.

[0018] This achieves the technical effect of accurately controlling the heater and thus the ambient temperature by determining a relatively accurate first monitoring temperature point. It also solves the technical problem in existing technologies where malfunctions of the thermal sensor at the temperature measurement point lead to the thermal control management system's inability to accurately control the heater and consequently, the ambient temperature.

[0033] Figure 2 A schematic diagram showing the connection relationship of the processor module 110, switch module 120, heater 130, and thermal sensor 140 disposed within the thermal control management system 10 according to an embodiment of this application is provided. (See reference) Figure 2 As shown, the thermal control management system 10 includes a processor module 110, a switch module 120, a heater 130, and a thermal sensor 140. The processor module 110 is connected to the switch module 120 and configured to send commands to the switch module 120. The switch module 120 is connected to the heater 130 and configured to turn the heater 130 on or off. The processor module 110 is connected to the thermal sensor 140 and configured to read the temperature value of the measuring point detected by the thermal sensor 140.

[0034] Furthermore, the thermal sensor 140 includes a plurality of thermal sensors 141-14n. Each of the thermal sensors 141-14n is configured to measure the temperature value at a corresponding temperature measurement point. Each temperature measurement point is located in the environment heated by the heater 130.

[0035] Figure 3 Multiple temperature measurement points are read by multiple thermal sensors 141-14n as described in the embodiments of this application. A schematic diagram. (Reference) Figure 3 As shown, multiple temperature measurement points are set up in the satellite system. The first thermal sensor 141 measures the temperature at the measuring point. Temperature value, second thermal sensor 142 measuring temperature point Temperature value, third thermal sensor 142 measuring temperature point The temperature value, and so on, the nth thermal sensor 14n measures the temperature at the same point. The temperature value. Multiple temperature measurement points. The temperatures can all be used to indicate the ambient temperature of the environment in which the heater 130 is located.

[0036] Then, the processor module 110 can read the temperature measurement point measured by the first thermal sensor 141. The processor module 110 can read the temperature value measured by the second thermal sensor 142 at the temperature measurement point. The processor module 110 can read the temperature value measured by the third thermal sensor 143 at the temperature measurement point. The processor module 110 can read the temperature value of the nth thermal sensor 14n, and so on. Temperature value.

[0037] In addition, multiple temperature measurement points For example, it may also include a first monitoring temperature point that is monitored by the processor module 110 and compared with a temperature threshold.

[0038] Under the aforementioned operating environment, according to the first aspect of this embodiment, a method for controlling a heater using a monitoring temperature measurement point is provided. This method can, for example, be [used by...]. Figure 2 The processor module 110 shown is implemented. Figure 4 A flowchart illustrating the method is shown below. (Refer to...) Figure 4 As shown, the method includes:

[0039] S402: Determine the first monitoring temperature measurement point from among multiple temperature measurement points set on the satellite system, for use in controlling the heater of the thermal control management system;

[0040] S404: Read the temperature value of the first monitoring temperature measurement point;

[0041] S406: Compare the temperature value of the first monitoring temperature point with a preset temperature threshold, wherein the temperature threshold indicates the maximum and minimum temperature values ​​that the first monitoring temperature point is allowed to reach; and

[0042] S408: Based on the comparison results, turn the heater in the thermal control management system on or off.

[0043] Specifically, refer to Figure 2 and Figure 3 As shown, multiple temperature measurement points are set up inside the satellite system. And multiple temperature measurement points Temperature values ​​at each temperature measuring point (i.e., the first) i At the moment, the first j The temperature value at each measuring point can represent the ambient temperature of the heater 130 at that moment. For example, the temperature measuring point Temperature value at time 1 That can represent The ambient temperature at this time. And at the same temperature measurement point... Temperature values ​​also vary at different times. For example, at the temperature measurement point... The temperature value at time 1 is The temperature value at time 2 is .

[0044] Therefore, the processor module 110 pre-measures from multiple temperature measurement points. The first monitoring and temperature measurement point is determined and used to control the thermal control management system (S402). This first monitoring and temperature measurement point consists of multiple temperature measurement points. One of the temperature measurement points This is used to provide the processor module 110 with the real-time temperature of the environment where the heater 130 is located and compare it with a temperature threshold. That is, the processor module 110 monitors the first temperature measurement point in real time. Monitor it.

[0045] Therefore, the thermal sensor 140 is connected to the first monitoring temperature measurement point The corresponding thermal sensor measures the first monitoring temperature point. temperature value Processor module 110 reads the temperature data from the first monitoring point. The first monitoring temperature point obtained by the corresponding thermal sensor measurement temperature value (S404). For example, refer to Figure 3 As shown, with the first monitoring temperature measurement point Corresponding to the second thermal sensor 142, the second thermal sensor 142 measures the value of the first monitoring temperature point. temperature value The temperature is 56℃.

[0046] In addition, the processor module 110 reads the first monitoring temperature measurement point. temperature value Then, the first monitoring and temperature measurement point temperature value The temperature is compared with a preset temperature threshold (S406). The temperature threshold indicates the maximum and minimum temperature thresholds allowed by the environment in which the heater 130 is located. It is worth noting that the maximum and minimum temperature thresholds can change according to the operating status of the satellite system. For example, when the satellite system is in long-term mode, the preset temperature threshold in the processor module 110 can be 57°C. When the satellite system is in pre-separation mode, the preset temperature threshold in processor module 110 can be... .

[0047] Finally, based on the comparison result, the processor module 110 sends a control command to the switch module 120 to control the opening or closing of the heater 130 installed in the thermal management system 10 (S408).

[0048] For example, processor module 110 monitors the temperature in real time from the first temperature measurement point. The corresponding thermal sensor receives the measured temperature value. When compared with the first monitoring temperature measurement point... The corresponding second thermal sensor 142 measures the first monitoring temperature point. temperature value When the temperature is 56℃, the processor module 110 reads the first monitored temperature point obtained from the measurement. temperature value And read the first monitoring temperature measurement point temperature value The temperature was compared with the preset maximum and minimum temperature thresholds. The maximum temperature threshold was 60℃, and the minimum temperature threshold was 57℃. The first monitoring temperature point was determined based on this comparison. temperature value The temperature is below the minimum temperature threshold (i.e., 56℃ < 57℃). Therefore, based on the comparison result, processor module 110 sends a control command to switch module 120 (i.e., "turn on" heater 130). Switch module 120 turns on heater 130 according to the control command. This allows for connection to multiple temperature measurement points. The corresponding ambient temperature can reach a reasonable threshold range. Conversely, when compared with the first monitoring temperature measurement point... corresponding Sensor 142 measures the first monitoring temperature point temperature value When the temperature is 61℃, the processor module 110 reads the first monitored temperature point obtained from the measurement. temperature value And read the first monitoring temperature measurement point temperature value The temperature is compared with the preset maximum and minimum temperature thresholds. The first monitoring temperature point is determined based on this comparison. temperature value The temperature exceeds the maximum temperature threshold (i.e., 61°C > 60°C). Therefore, based on the comparison result, the processor module 110 sends a control command to the switch module 120 (i.e., "turn off" the heater 130). This controls the temperature of the environment where the heater 130 is located to be near the target temperature.

[0049] As described in the background section, temperature measurement points are also set within the satellite system, each equipped with a thermal sensor 140 for measuring temperature. The thermal control management system 10 in the satellite system can control the heater 130 to turn on or off by reading the temperature value at the temperature measurement point and comparing it with preset maximum temperature thresholds (i.e., the first temperature threshold) and minimum temperature thresholds (i.e., the second temperature threshold). However, since the thermal control management system 10 controls the heater 130 based on the temperature at the temperature measurement point, if the thermal sensor 140 malfunctions, the incorrect temperature value measured by the thermal sensor 140 will cause the thermal control management system 10 to be unable to accurately control the heater 130, thereby failing to accurately control the ambient temperature.

[0050] In view of this, multiple temperature measurement points are provided in the embodiments of this disclosure. Therefore, the technical solution disclosed herein can also ensure that even at the first monitoring temperature measurement point, backup monitoring temperature measurement points are identified. In the event of an anomaly, the thermal control management system 10 can also accurately control the technical performance of the heater 130. Specifically, the technical solution disclosed herein also includes a second monitoring and temperature measurement point. The second monitoring and temperature measurement point is the first monitoring and temperature measurement point. The backup temperature measurement point. That is, when the first monitoring temperature measurement point... When an anomaly occurs (e.g., at the first monitoring temperature measurement point) The corresponding second thermal sensor 142 cannot read the first monitoring temperature measurement point. Temperature value or the first monitoring temperature measurement point (e.g., communication failure between the corresponding second thermal sensor 142 and the processor module 110), the processor module 110 can accurately control the heater 130 by reading the temperature value of the second monitoring temperature measurement point.

[0051] Optionally, based on the comparison result, the operation of turning the heater on or off within the thermal control management system includes: turning off the heater when the temperature value at the first monitoring temperature point is greater than a first temperature threshold; and turning on the heater when the temperature value at the first monitoring temperature point is less than a second temperature threshold, wherein the second temperature threshold is less than the first temperature threshold.

[0052] Specifically, refer to Figure 2 and Figure 3As shown, if the processor module 110 determines the first monitoring temperature measurement point temperature value If the temperature exceeds the preset maximum temperature threshold (i.e., the first temperature threshold), the processor module 110 sends a control command to the switch module 120 to "turn off" the heater 130. In response to the control command sent by the processor module 110, the switch module 120 turns off the heater 130, preventing it from continuously heating the working environment of multiple devices within the satellite system, thus ensuring the normal operation of these devices and preventing damage to them.

[0053] If the processor module 110 determines the first monitoring temperature measurement point temperature value If the temperature is below a preset minimum temperature threshold (i.e., the second temperature threshold), the processor module 110 sends a control command to the switch module 120 to "turn on" the heater 130. In response to the control command, the switch module 120 turns on the heater 130. This allows the heater 130 to heat the satellite system's environment, ensuring that the equipment within the satellite system can operate normally in a suitable temperature environment.

[0054] Thus, the processor module 110 monitors the first temperature measurement point. temperature value By comparing the temperature with the preset maximum and minimum temperature thresholds and controlling the opening or closing of the heater 130 based on the comparison results, the technical effect of ensuring the normal operation of multiple devices within the satellite system is achieved.

[0055] Furthermore, the processor module 110 can periodically send measurement commands to the thermal sensor 140 at preset time intervals. That is, the thermal sensor 140 periodically measures multiple temperature points. The temperature value. This ensures that, in the event of abnormal ambient temperatures affecting multiple devices within the satellite system, the technical effectiveness of the system can be achieved by promptly detecting and resolving problems.

[0056] Optionally, the operation of determining the first monitoring temperature measurement point from multiple temperature measurement points set on the satellite system includes: determining a reference temperature value corresponding to different times; determining the average deviation value corresponding to each temperature measurement point based on the temperature values ​​of multiple temperature measurement points at different times and the reference temperature values ​​at different times; determining the variance of the deviation value corresponding to each temperature measurement point based on the temperature values ​​of multiple temperature measurement points at different times and the reference temperature values ​​at different times; and determining the first monitoring temperature measurement point based on the average deviation value of multiple temperature measurement points corresponding to each temperature measurement point and the variance of the deviation value of multiple temperature measurement points corresponding to each temperature measurement point.

[0057] Specifically, refer to Figure 2 and Figure 3 As shown, firstly, the processor module 110 needs to determine the reference temperature values ​​corresponding to different times according to the following operating steps: Specifically, the first thermal sensor 141 measures the temperature at... Time and its corresponding temperature measurement point temperature value The second thermal sensor 142 measures at Time and its corresponding temperature measurement point temperature value The third thermal sensor 143 measures at Time and its corresponding temperature measurement point temperature value And so on, the nth thermal sensor 14n measures at Time and its corresponding temperature measurement point temperature value .

[0058] Therefore, processor module 110 reads Temperature measurement point at all times Temperature value ,exist Temperature measurement point at all times Temperature value ,exist Temperature measurement point at all times Temperature value And so on, in Temperature measurement point at all times Temperature value .

[0059] Then, the first thermal sensor 141 responds to the measurement at Time and its corresponding temperature measurement point temperature value The second thermal sensor 142 measures at Time and its corresponding temperature measurement point temperature value The third thermal sensor 143 measures at Time and its corresponding temperature measurement point temperature value And so on, the nth thermal sensor 14n measures at Time and its corresponding temperature measurement point temperature value .

[0060] Therefore, processor module 110 reads Temperature measurement point at all times Temperature value ,exist Temperature measurement point at all times Temperature value ,exist Temperature measurement point at all times Temperature value And so on, in Temperature measurement point at all times Temperature value .

[0061] Repeat the above operating steps, and the first thermal sensor 141 measures the temperature at... Time and its corresponding temperature measurement point temperature value The second thermal sensor 142 measures at Time and its corresponding temperature measurement point temperature value The third thermal sensor 143 measures at Time and its corresponding temperature measurement point temperature value And so on, the nth thermal sensor 14n measures at Time and its corresponding temperature measurement point temperature value .

[0062] Therefore, processor module 110 reads Temperature measurement point at all times Temperature value ,exist Temperature measurement point at all times Temperature value ,exist Temperature measurement point at all times Temperature value And so on, in Temperature measurement point at all times Temperature value .

[0063] Then, processor module 110 statistics Temperature measurement point at all times Temperature value Temperature measurement point Temperature value Temperature measurement point temperature value and temperature measurement points temperature value The temperature distribution range. Specifically, the processor module 110 divides the temperature distribution range into: There are several temperature intervals, each with a granularity of 0.5℃. For example, temperature interval 1 is... Temperature range 2 is Temperature range 3 is And so on, temperature range for .

[0064] In addition, the processor module 110 counts the number of temperature measurement points corresponding to each interval. For example, temperature interval The corresponding number of temperature measurement points is Temperature range The corresponding number of temperature measurement points is Temperature range The corresponding number of temperature measurement points is And so on, temperature range The corresponding number of temperature measurement points is .

[0065] Furthermore, calculate and respectively ~ Corresponding weight value The specific calculation formula is as follows:

[0066] (Formula 1)

[0067] in, y =1~ l 1 .

[0068] Then, the processor module 110 calculates the average value of each temperature range to obtain the average temperature of the range.

[0069] For example, temperature range There is There are several temperature measurement points, and they correspond to a temperature range. The corresponding average temperature is Temperature range There is There are several temperature measurement points, and they correspond to a temperature range. The corresponding average temperature is Temperature range There is There are several temperature measurement points, and they correspond to a temperature range. The corresponding average temperature is And so on, temperature range There is There are several temperature measurement points, and they correspond to a temperature range. The corresponding average temperature is .

[0070] For the temperature range ~ Perform weighted summation and determine the time interval. Corresponding reference temperature value The specific calculation formula is as follows:

[0071] (Formula 2)

[0073] Therefore, the time can be obtained by performing the above operations. Corresponding reference temperature value Furthermore, with time Corresponding reference temperature value and time Corresponding reference temperature value ... and time Corresponding reference temperature value All of these can be obtained by referring to the above steps.

[0074] Furthermore, the processor module 110 adjusts according to different times. ~ Corresponding multiple temperature measurement points Temperature value and reference temperature value ~ Determine the connection with each temperature measurement point Corresponding mean deviation ~ Specifically, firstly, the processor module 110 determines the temperature based on multiple temperature measurement points. Temperature value and reference temperature value Determine at different times ~ Inside, with multiple temperature measurement points Corresponding multiple temperature deviations ~ For example, at time 1, at each temperature measurement point The temperature deviation is calculated using the following formula:

[0075] (Formula 3)

[0110] Table 3.3

[0111]

[0112] Therefore, with multiple temperature measurement points Corresponding deviation variance ~ All of these can be obtained through the operations described above.

[0113] Finally, the processor module 110 calculates the temperature at each measurement point. Corresponding mean deviation ~ and various temperature measurement points Corresponding deviation variance ~ The first monitoring and temperature measurement point was determined.

[0114] Optionally, the operation of determining the first monitoring temperature measurement point based on the mean deviation of multiple temperature measurement points corresponding to different times and the variance of the deviation of multiple temperature measurement points corresponding to different times includes: determining the threshold range corresponding to multiple temperature measurement points; determining the temperature measurement point with the largest probability distribution value among multiple temperature measurement points based on the threshold range, the mean deviation of multiple temperature measurement points corresponding to each temperature measurement point, and the variance of the deviation of multiple temperature measurement points corresponding to each temperature measurement point; and taking the temperature measurement point with the largest probability distribution value among multiple temperature measurement points as the first monitoring temperature measurement point.

[0115] Specifically, refer to Figure 2 and Figure 3 As shown, firstly, the processor module 110 obtains the preset deviation range. ~ Among them, the deviation range ~ For example, it could be sent by a staff member to processor module 110.

[0116] Then, the processor module 110 determines the deviation range. ~ The average deviation from the corresponding temperature measurement points ~ and the variance of the deviation corresponding to each temperature measurement point ~ Determine multiple temperature measurement points Medium temperature deviation ~ Falling into the deviation range ~ The temperature measurement point with the highest probability. Specifically, Figure 5 The temperature measuring point is as described in the embodiments of this application. Temperature measurement point Temperature measurement point and temperature measurement point A schematic diagram of the normal distribution curve corresponding to the temperature deviation. (Reference) Figure 5 As shown, the processor module 110 has a pre-set deviation range. ~ Therefore, within the preset deviation range ~ Inside, with temperature measurement point The area of ​​the corresponding normal distribution curve 1 and the temperature measurement point The area of ​​the corresponding normal distribution curve 2 and the temperature measurement point The area of ​​the corresponding normal distribution curve 3 and the temperature measurement point The corresponding areas of the normal distribution curve 4 are different. That is, the temperature measurement points... temperature deviation Falling within the deviation range ~ The probability value N1 within the temperature measurement point temperature deviation Falling within the deviation range ~ The probability value N2 within the temperature measurement point temperature deviation Falling within the deviation range ~ The probability value N3 and the temperature measurement point within. temperature deviation Falling within the deviation range ~ The probability distribution value N4 within the range is different.

[0117] Then, the processor module 110 calculates the temperature measurement points using the following formulas. The corresponding probability value N1 and the temperature measurement point The corresponding probability value N2, and the temperature measurement point The corresponding probability value N3 and the temperature measurement point The corresponding probability value is N4. The specific calculation formula is as follows:

[0118] (Formula 6)

[0119] (Formula 7)

[0120] Among them, among them, j =1~n.

[0121] Finally, the processor module 110 calculates the multiple temperature measurement points. Medium temperature deviation ~ The temperature measurement point with the highest probability of falling within the deviation range is designated as the first monitoring temperature measurement point.

[0122] Therefore, the processor module 110 determines the reference temperature value. Determine the location of each temperature measurement point. Corresponding mean deviation ~ Determine the location of each temperature measurement point. Corresponding deviation variance ~ And determine each temperature measurement point temperature deviation ~ Falling into the deviation range ~ By operating on the probability value within the range, the temperature measurement point with the highest probability of falling within the required deviation range is determined as the first monitoring temperature measurement point. This, in turn, allows for the determination of temperature measurement points with higher measurement accuracy as monitoring temperature measurement points, thereby enabling more accurate control of the ambient temperature of the heater.

[0123] Optionally, it also includes: if the temperature value of the first monitoring temperature measurement point is greater than the temperature threshold, the first monitoring temperature measurement point is replaced with a second monitoring temperature measurement point, wherein the second monitoring temperature measurement point is a backup monitoring temperature measurement point.

[0124] Specifically, Figure 6 This is a schematic diagram illustrating the arrangement of a first monitoring temperature measurement point and a second monitoring temperature measurement point according to an embodiment of this application. (Reference) Figure 6 As shown, the second thermal sensor 142, corresponding to the first monitoring temperature point, measures the temperature value of the first monitoring temperature point. Then, the processor module 110 reads the temperature value of the first monitoring temperature measurement point. .

[0125] Then, the processor module 110 will display the temperature value of the first monitoring temperature measurement point. The temperature value at the first monitoring point is compared with a preset temperature threshold. The temperature is much higher than the preset temperature threshold. That is, the temperature value at the first monitoring point... The temperature value is much higher than the maximum allowable temperature value of the first monitoring temperature measurement point. This indicates that the selection of the first monitoring temperature measurement point may be accidental or that the first monitoring temperature measurement point is abnormal. Therefore, the processor module 110 replaces the first monitoring temperature measurement point with the second monitoring temperature measurement point, sends a measurement command to the third thermal sensor 143 corresponding to the second monitoring temperature measurement point, and reads the temperature value of the second monitoring temperature measurement point. .

[0126] If the processor module 110 reads the temperature value of the second monitoring temperature point If the temperature value is still greater than the preset temperature threshold, it indicates that the ambient temperature of the equipment within the satellite system is abnormal and needs to be adjusted promptly; if the temperature value read by the processor module 110 from the second monitoring temperature measurement point... If the temperature is less than the preset threshold, it indicates that the selection of the first monitoring temperature measurement point may be accidental or that the first monitoring temperature measurement point is abnormal.

[0127] Then, the temperature value at the second monitoring temperature measurement point. If the temperature is below a preset threshold, the processor module 110 needs to further determine the cause of the anomaly at the first monitoring temperature point. Specifically, the second thermal sensor 142 corresponding to the first monitoring temperature point may be unable to read the temperature value of the first monitoring temperature point, or there may be a communication failure between the second thermal sensor 142 corresponding to the first monitoring temperature point and the processor module 110.

[0128] Thus, by setting up backup monitoring and temperature measurement points, the processor module 110 achieves the technical effect of avoiding the randomness in the selection of the first monitoring and temperature measurement point, thereby ensuring that the temperature value of the read monitoring and temperature measurement point can be used to indicate the ambient temperature of multiple devices within the satellite system.

[0129] Optionally, it also includes: changing the temperature threshold when the heater's operating mode changes.

[0130] Specifically, because the satellite system has multiple operating modes, the temperature thresholds corresponding to these modes are also different. For example, Table 4 shows the various temperature thresholds corresponding to different operating modes.

[0131] Table 4

[0132]

[0133] Referring to Table 4, the preset temperature thresholds for the processor module 110 corresponding to the pre-separation mode are (40℃, 45℃), the preset temperature thresholds for the processor module 110 corresponding to the initial orbit insertion mode are (100℃, 106℃), the preset temperature thresholds for the processor module 110 corresponding to the long-term mode are (57℃, 60℃), and the preset temperature thresholds for the processor module 110 corresponding to the emergency safety mode are (10℃, 12℃).

[0134] For example, the satellite system's operating mode changes from initial orbit mode to long-term mode, so the temperature threshold in processor module 110 changes from (100°C, 106°C) to (57°C, 60°C).

[0135] Thus, by selecting an appropriate temperature threshold according to the operating mode of the satellite system, the processor module 110 achieves the technical effect of timely adjusting the ambient temperature within the satellite system based on its operating status.

[0136] Figure 7 This is a schematic flowchart illustrating a method for controlling the opening and closing of the heater 130 within the thermal control management system 10 based on monitored temperature points, according to an embodiment of this application. (See reference) Figure 7 As shown,

[0137] S710: The processor module 110 determines the reference temperature value corresponding to different times, and determines the mean deviation and variance of the deviation of multiple temperature measurement points based on the temperature values ​​of multiple temperature measurement points and the reference temperature value, respectively.

[0138] S720: The processor module 110 determines the deviation range, and based on the deviation range, the mean deviation of multiple temperature measurement points at different times, and the variance of the deviation of multiple temperature measurement points at different times, determines the temperature measurement point with the largest probability distribution value among multiple temperature measurement points. The temperature measurement point with the largest probability distribution value among multiple temperature measurement points is the first monitoring temperature measurement point.

[0139] S730: Processor module 110 reads the temperature value of the first monitoring temperature measurement point;

[0140] S740: Processor module 110 compares the temperature value of the first monitored temperature point with a preset temperature threshold.

[0141] S751: If the temperature value at the first monitoring temperature measurement point is greater than the temperature threshold, the processor module 110 issues a command to shut down the heater 130.

[0142] S752: If the temperature value at the first monitoring temperature point is less than the temperature threshold, the processor module 110 issues a command to turn on the heater 130.

[0143] S760: If the temperature value at the first monitoring temperature measurement point is greater than the temperature threshold, the processor module 110 will replace the first monitoring temperature measurement point with the second monitoring temperature measurement point; and

[0144] S770: When the operating mode of the satellite system 10 changes, the processor module 110 changes the temperature threshold.

[0145] Therefore, in the embodiments of this disclosure, the processor module 110 pre-selects a first monitoring temperature measurement point for monitoring by the processor module 110 at different times and comparing it with a temperature threshold. The first monitoring temperature point measured by the thermal sensor 140 temperature value The temperature is compared with a preset temperature threshold. Therefore, the processor module 110 does not need to read multiple temperature measurement points. Instead of choosing the exact temperature value, a primary monitoring temperature measurement point with a more accurate measurement result is selected. And read the first monitoring temperature measurement point temperature value By comparing the temperature with a preset temperature threshold, a comparison result can be obtained, and the heater 130 can be controlled to open or close based on the comparison result. This achieves the goal of determining a relatively accurate first monitoring temperature point. This achieves the technical effect of accurately controlling the heater 130, and thus accurately controlling the working environment temperature. It also solves the technical problem in the prior art where an malfunction in the thermal sensor 140 at the temperature measurement point would cause the thermal control management system 10 to be unable to accurately control the heater 130, thereby failing to accurately control the working environment temperature.

[0146] Furthermore, according to a second aspect of this embodiment, a system for controlling a heater 130 using a temperature measuring point is provided, applied to a thermal control management system 10. The thermal control management system 10 includes a processor 110, a heater 130, and a thermal sensor 140, wherein the processor 110 is connected to the heater 130 and the thermal sensor 140. The processor 110 determines a first monitoring temperature measuring point among a plurality of temperature measuring points set on a satellite system and controls the heater 130 of the thermal control management system 10. The processor 110 reads the temperature value of the first monitoring temperature measuring point measured by the heater 130. The processor 110 compares the temperature value of the first monitoring temperature measuring point with a preset temperature threshold, wherein the temperature threshold is used to indicate the maximum and minimum temperature values ​​that the first monitoring temperature measuring point is allowed to reach. The processor 110 turns the heater 130 in the thermal control management system 10 on or off according to the comparison result.

[0147] Therefore, in the embodiments of this disclosure, the processor module 110 pre-selects a first monitoring temperature measurement point for monitoring by the processor module 110 at different times and comparing it with a temperature threshold. The first monitoring temperature point measured by the thermal sensor 140 temperature value The temperature is compared with a preset temperature threshold. Therefore, the processor module 110 does not need to read multiple temperature measurement points.

And read the first monitoring temperature measurement point temperature value By comparing the temperature with a preset temperature threshold, a comparison result can be obtained, and the heater 130 can be controlled to open or close based on the comparison result. This achieves the goal of determining a relatively accurate first monitoring temperature point. This achieves the technical effect of accurately controlling the heater 130, and thus accurately controlling the working environment temperature. It also solves the technical problem in the prior art where an malfunction in the thermal sensor 140 at the temperature measurement point would cause the thermal control management system 10 to be unable to accurately control the heater 130, thereby failing to accurately control the working environment temperature.

[0148] In addition, refer to Figure 2As shown, according to a third aspect of this embodiment, a storage medium is provided. The storage medium includes a stored program, wherein, when the program is executed, a processor performs any of the methods described above.

[0149] Therefore, in the embodiments of this disclosure, the processor module 110 pre-selects a first monitoring temperature measurement point for monitoring by the processor module 110 at different times and comparing it with a temperature threshold. The first monitoring temperature point measured by the thermal sensor 140 temperature value The temperature is compared with a preset temperature threshold. Therefore, the processor module 110 does not need to read multiple temperature measurement points.
