Description

Technical Field

[0001] The present application relates to the field of satellite technology, and in particular to a control method, device, electronic equipment and medium for a satellite power management system. Background Art

[0002] Currently, in commercial aerospace, cost control is an important issue in satellite engineering. The way to achieve low cost in low-orbit satellite engineering is to replace aerospace-grade components with ordinary industrial-grade or automotive-grade components after specific technical processing. For example, ordinary industrial-grade or automotive-grade power management units are used to replace aerospace-grade power management units, and are installed in low-orbit satellites to manage power supply and power failure of various operating equipment of low-orbit satellites.

[0003] Since the performance indicators of each phase of ordinary industrial-grade or automotive-grade power management units are generally lower than those of aerospace-grade power management units, in order to improve the reliability of power management units, redundant designs are often adopted for power management units in commercial aerospace, that is, one main and one backup or one main and two backups, or even one main and multiple backups, thereby forming a power management system. In the event of a failure in the main power management unit, the backup management unit will perform the task.

[0004] However, the inventors of the present application have discovered that the design of existing ordinary industrial-grade or automotive-grade power management units is limited by their own performance indicators, and the relevant parameters of the running devices managed by the power management units obtained by the power management units may be excessively distorted, thereby affecting the diagnosis results of whether the running devices managed by them have faults, that is, the power management system has low ability to diagnose equipment faults.

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the drawings in the embodiments of the present application are collected below to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The present application provides a power management system, which is installed on a satellite. The power management system includes multiple power management units, each of which is connected to multiple operating devices of the satellite, and is used to receive operating parameters of the multiple operating devices, generate device monitoring information based on the operating parameters, and send the device monitoring information to the electronic device.

[0045] An embodiment of the present application provides a control method for a power management system of a satellite, which can be executed by an electronic device, wherein the electronic device can be a server, wherein the server can be an independent physical server, or a server cluster or distributed device composed of multiple physical servers, or a cloud server providing cloud computing services; the server can be installed on a ground communication terminal or on a satellite.

[0046] Reference Figure 1 A control method for a satellite power management system includes: step S101, step S102 and step S103, wherein:

[0047] S101, when abnormal information of a target operating device among a plurality of operating devices is acquired, device association information and a device operating level corresponding to the target operating device are determined.

[0048] In some embodiments, the abnormal information is information about abnormal parameters involved in the operation of the target operating device; the equipment association information is information about whether the target operating device has an operation association with other operating devices in the satellite; the equipment operation level is the operation importance level of the target operating device among all operating devices contained in the satellite.

[0049] All operating equipment included in the satellite is equipped with early warning equipment. When the operating equipment is operating normally, the early warning equipment does not issue early warning information. When the operating equipment is operating abnormally, the early warning equipment issues early warning information and sends the early warning information to the electronic equipment. The electronic equipment obtains abnormal information of the target operating equipment corresponding to the early warning information based on the early warning information. When the electronic equipment obtains the abnormal information, it indicates that there is a risk of damage to the target operating equipment at this time. Then, the electronic equipment obtains the operating status and equipment parameters of the target operating equipment, analyzes them, and determines the equipment-related information and equipment operation level of the target operating equipment based on the analysis results.

[0050] S102, based on the device association information and the device operation level, determine multiple target power management units corresponding to the target operation device from multiple power management units, and obtain the corresponding device monitoring information.

[0051] In some embodiments, the device association information reflects the degree of association between the target operating device and other operating devices in the satellite; the device operation level reflects the importance of the target operating device in the satellite operation process; that is, when the device association information shows that the target operating device is associated, the less optimistic the operating condition of the target operating device is, the greater the impact on other operating devices in the satellite; when the device association information shows that the target operating device is not associated, it indicates that the operating condition of the target operating device will not affect other operating devices in the satellite; in addition, the higher the device operation level, the greater the negative impact of a failure of the target operating device on the satellite; the lower the device operation level, the smaller the negative impact of a failure of the target operating device on the satellite.

[0052] Then, in the process of determining multiple target power management units corresponding to the target operating device from multiple power management units, multiple target power management units whose number is adapted to the target operating device can be determined based on the device association information and the device operating level, and their corresponding device monitoring information can be obtained, thereby ensuring the accuracy of the subsequent judgment of whether the target operating device has a fault based on the device monitoring information obtained from the multiple target power management units.

[0053] S103, generating a device power-off instruction based on multiple device monitoring information, and controlling the satellite power supply to power off the target operating device based on the device power-off instruction.

[0054] In some embodiments, the electronic device judges and analyzes multiple device monitoring information, and determines whether it is necessary to power off the target operating device based on the analysis results; when it is determined that the target operating device needs to be powered off, the electronic device generates a device power-off instruction, and sends the device power-off instruction to the power control unit corresponding to the target operating device; the power control unit controls the target operating device to be disconnected from the satellite power supply in response to the device power-off instruction, thereby powering off the target operating device; thereby, by determining the device association information and device operating level corresponding to the target operating device, multiple target power management units of the same number as the target operating device are determined from a large number of power management units, and based on the device monitoring information of the multiple target power management units, a decision is made as to whether to power off the target operating device, thereby improving the ability of the power management unit to diagnose device faults.

[0055] In step S101, the device association information and the device operation level corresponding to the target operating device are determined, including: obtaining the operating status and device parameters of the target operating device; determining the device connection information of the target operating device based on the device parameters; determining the work task information of the target operating device based on the operating status; determining the device association information based on the device connection information and the work task information; and determining the device operation level of the target operating device based on the device association information and the device parameters.

[0056] In some embodiments, the device parameters include connection parameters between devices, parameter variation ranges during device operation, and device types, etc.; the operating status includes the operating stage.

[0057] The electronic device first obtains the operating status and device parameters of the target operating device, and obtains the connection parameters between the devices by analyzing the device parameters; the electronic device determines the device connection information of the target operating device based on the connection parameters between the devices; at the same time, the electronic device analyzes the operating status to determine the operating stage of the target operating device, and determines the work task information currently being executed by the target operating device based on the operating stage; the electronic device determines the current device association information of the target operating device through the device association information and the work task information; at the same time, the electronic device determines the importance of the device parameters in the satellite operation process, and determines the device operation level of the target operating device based on the device association information.

[0058] In step S102, based on the device association information and the device operation level, multiple target power management units corresponding to the target operation device are determined from multiple power management units, including: when the device association information shows that the device is associated, based on the device operation level and a first preset number screening rule, multiple target power management units corresponding to the target operation device are determined from multiple power management units; when the device association information shows that the device is not associated, based on the device operation level and a second preset number screening rule, multiple target power management units corresponding to the target operation device are determined from multiple power management units.

[0059] In some embodiments, the electronic device determines whether the device association information of the target operating device is associated; when it is determined that the device association information is associated, it indicates that the operation of the target operating device will affect the operation of other operating devices in the satellite. Therefore, the requirements for judging the operating status of the target operating device are higher, and more device monitoring information is needed for judgment; then, the electronic device calls a first preset number screening rule preset in advance, and determines multiple target power management units corresponding to the target operating device from multiple power management units according to the first preset number screening rule.

[0060] When the electronic device determines that the device association information shows that there is no device association, it indicates that the operation of the target operating device will not affect the operation of other operating devices in the satellite. Therefore, the requirements for judging the operating status of the target operating device can be relatively low, and then there is no need for too much device monitoring information to make a judgment; then, the electronic device calls up a second preset number screening rule preset in advance, and determines multiple target power management units corresponding to the target operating device from multiple power management units.

[0061] In some embodiments, the first preset number screening rule and the second preset number screening rule are subjectively set by technicians; the number of multiple target power management units screened out by the electronic device based on the first preset number screening rule is greater than the number of multiple target power management units screened out based on the second preset number screening rule.

[0062] In some embodiments, when the device association information indicates that the device is associated, based on the device operating level and a first preset number screening rule, multiple target power management units corresponding to the target operating device are determined from multiple power management units, including: when the device association information indicates that the device is associated, and the device operating level is the lowest level, based on the first preset number included in the first preset number screening rule, multiple target power management units corresponding to the target device are determined from multiple power management units; when the device association information indicates that the device is associated, and the device operating level is the second lowest level, based on the second preset number included in the first preset number screening rule, multiple target power management units corresponding to the target device are determined from multiple power management units; when the device association information indicates that the device is associated, and the device operating level is the highest level, based on the third preset number included in the first preset number screening rule, multiple target power management units corresponding to the target device are determined from multiple power management units.

[0063] In some embodiments, the electronic device determines the device operation level of the target operating device. When the electronic device determines that the device association information indicates that the device is associated and the device operation level is at the lowest level, it indicates that the importance level of the target operating device is the lowest, and the number of target power management units corresponding to the target operating device that needs to be determined is the lowest. The electronic device then determines multiple target power management units corresponding to the target device from multiple power management units based on the first preset number in the first preset number screening rule.

[0064] When the electronic device determines that the device association information shows that the device is associated and the device operation level is at a sub-low level, it indicates that the importance level of the target operating device is low, and the number of target power management units corresponding to the target operating device that needs to be determined is second lowest. The electronic device then determines multiple target power management units corresponding to the target device from the power management units based on the second preset number in the first preset number screening rule.

[0065] When the electronic device determines that the device association information indicates that the device is associated and the device operation level is the highest level, it indicates that the importance level of the target operating device is the highest, and the number of target power management units corresponding to the target operating devices that need to be determined is the highest. Then, the electronic device determines multiple target power management units corresponding to the target device from the power management unit based on the second preset number in the second preset number screening rule, wherein the first preset number, the second preset number and the third preset number are subjectively set by the technicians, and their specific values ​​are not specifically limited in the embodiments of the present application.

[0066] In some embodiments, since the satellite contains multiple operating devices, it is not ruled out that at least two operating devices may malfunction at the same time, and the electronic device may obtain at least two abnormal information. In this case, it is necessary to clearly determine the order of target power management units corresponding to at least two operating devices from multiple power management units and the number of their respective corresponding target power management units.

[0067] That is, the target operating device includes at least two target operating devices; at this time, in step S102, based on the device association information and the device operating level, multiple target power management units corresponding to the target operating device are determined from multiple power management units, including: based on the device association information, determining the association information between at least two target operating devices; when the association information shows that there is no association between at least two target operating devices, and the operating levels of at least two target operating devices are not equal, preferentially determining multiple target power management units corresponding to the target operating device with a high operating level from the multiple target power management units, and determining multiple target power management units corresponding to the target operating device with a low operating level from other target power management units except the multiple target power management units.

[0068] In some embodiments, the electronic device determines whether there is an association between at least two target operating devices based on device association information, that is, the electronic device determines the association information between the two; when the electronic device determines that the association information shows that there is no association between the at least two target operating devices, it indicates that the causes of the abnormality between the two are different; at the same time, the electronic device determines the device operating levels of the at least two target operating devices, and when it is determined that the operating levels of the at least two target operating devices are not equal, the electronic device determines the target power management units corresponding to the at least two target operating devices in order according to the high and low device operating levels, that is, it preferentially determines from multiple target power management units the multiple target power management units corresponding to the target operating devices with high operating levels.

[0069] Subsequently, the electronic device determines multiple target power management units corresponding to target operating devices with low operating levels from the remaining power management units, thereby reducing the occurrence of the power management unit detecting multiple target operating devices at the same time, reducing the operating load of the power management unit, and improving the accuracy of the device monitoring information of the power management unit.

[0070] In some embodiments, after determining the association information between at least two target operating devices based on the device association information, multiple target power management units corresponding to the target operating devices are determined from multiple power management units based on the device association information and the device operating level, and also includes: when the association information shows that there is no association between the at least two target operating devices, and the operating levels of the at least two target operating devices are the highest level, based on a fourth preset number, multiple target power management units corresponding to the at least two target devices are determined from multiple power management units, wherein the fourth preset number is greater than fifty percent of the total number of the multiple target power management units.

[0071] In some embodiments, when the association information shows that there is no association between at least two target operating devices, and the operating levels of at least two target operating devices are both the highest level, multiple target power management units corresponding to the at least two target operating devices are randomly determined based on a fourth preset number. Since the number of multiple target power management units determined based on the fourth preset number is greater than half of the total number of power management units, in the subsequent process of determining multiple target power management units of other target operating devices in the at least two target operating devices based on the fourth preset number, the electronic device first obtains and determines the number of power management units in the multiple power management units that need to monitor at least two target operating devices simultaneously.

[0072] At the same time, the electronic device obtains the operation load information corresponding to the multiple target power management units of the target operation that have been determined to have been completed, and sorts the multiple target power management units in order of the multiple operation load information from small to large. When determining the multiple target power management units of other target operating devices, based on the number of power management units that need to monitor at least two target operating devices at the same time, the multiple target power management units for other target operating devices are screened out from the multiple target power management units that have completed the sorting, thereby reducing the occurrence of distortion of the generated device monitoring information due to excessive power management operation load.

[0073] In step S103, based on multiple device monitoring information, a device power-off instruction is generated, including: comparing the multiple device monitoring information with the preset monitoring results respectively; retaining the device monitoring information that meets the preset monitoring results, and recording the number of device monitoring information that meets the preset monitoring results; when the number meets the preset number, generating a device power-off instruction.

[0074] In some implementations, the preset monitoring result is the parameter range of the monitored parameter; the electronic device compares multiple device monitoring information with the preset monitoring result respectively, and determines whether the multiple device monitoring information are within the preset monitoring result. When the device monitoring information is within the device monitoring result, the electronic device records the device monitoring information and records the number of device monitoring information within the device monitoring result; then, the electronic device compares the number with the preset number. When it is determined that the number meets the preset number, it indicates that the target running device has a fault and needs to be powered off, and the electronic device then generates a device power-off instruction.
