Description

Technical Field

[0001] This invention relates to the field of mass production satellite testing technology, specifically to a dynamic scheduling system and method for power supply resources of a solar simulation array, and more particularly to a dynamic scheduling system and method for power supply resources of a solar simulation array that supports parallel testing of multiple satellites. Background Technology

[0002] The construction of China's low-Earth orbit satellite constellation has entered an accelerated phase, and batch testing of satellites has become a routine scenario in large-scale development. As the main power supply equipment during the satellite ground testing phase, the demand for solar simulation arrays has increased significantly in batch testing scenarios, accounting for a high proportion of both the investment cost and power cost of the testing system.

[0003] During satellite testing, power input requirements fluctuate dynamically with varying testing conditions. If a single satellite is configured with its full power supply channels, only a portion of these channels are typically operational, while the remaining channels remain idle. Therefore, allocating full power supply channels to each satellite individually would not only incur high equipment costs but also place significant pressure on the satellite production line's power supply system due to their continuous high power consumption. Thus, in multi-satellite parallel testing scenarios, adopting a dynamic scheduling model based on demand, according to the satellite's operating status, to coordinate the power supply resources of the solar simulation array is a crucial means to improve equipment utilization and reduce resource investment.

[0004] Patent document CN101877555 discloses a method for constructing a solar array simulation system for parallel testing of multiple satellites. This method, taking into account the characteristics of small satellites—low power and highly dispersed power requirements—and the development of small satellite networking technology, integrates multiple identical solar array simulators. By analyzing the power requirements of each satellite, it allocates power to multiple satellites from the solar arrays within the system. The configuration is flexible, enabling a single system to test multiple satellites simultaneously. The implementation involves power allocation based on the number of satellites, their interfaces, and the number of solar arrays within the system. Corresponding adapter cables are designed to distribute the system's output energy to multiple satellites under test. The adapter cables allow for flexible use of general-purpose equipment, effectively saving testing resources, costs, and space.

[0005] However, the core of the aforementioned patent documents is to utilize the backup equipment in the standard solar analog array cabinet through the configuration of the adapter cable to power multiple satellites, which cannot achieve dynamic allocation of power resources.

[0006] Patent document CN119803983 provides a batch satellite thermal test dynamic allocation automatic test system and application method. Multiple load test devices, telemetry and control test devices, test interface devices, and energy equipment channels are connected to the flanges corresponding to each interface through satellite cables and switch matrices. During the thermal test, the corresponding ground test channels of each equipment group are controlled to connect to the corresponding satellite under test at a preset time. The system generates configuration files and automatic control task sequences for the communication payload, telemetry and control components, test interfaces, and energy components of the satellite under test, and outputs a timing task sheet.

[0007] The aforementioned patent documents can achieve dynamic allocation of power supply resources during the test to some extent, but they have two drawbacks: First, the cost of using a switch matrix board for power supply resource switching is high, the number of circuits is small, the load capacity is poor, and the reliability is low. Second, the power supply resource allocation is based solely on the automatic test sequence generated by the test conditions, without an autonomous scheduling strategy, resulting in low efficiency and security of power supply resource allocation. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the purpose of this invention is to provide a dynamic scheduling system and method for power supply resources of a solar simulation array.

[0009] A dynamic scheduling system for power supply resources of a solar simulation array, provided by the present invention, includes: The power supply control module is used to control the power supply path of the solar simulation array, as well as the on / off state of the programmable magnetic latching relay in the programmable relay module, and to send the working status parameters of the solar simulation array to the analysis and scheduling module. The telemetry receiving module is used to receive telemetry data and power supply scheduling instructions from the satellite under test, and send them to the analysis and scheduling module. The analysis and scheduling module comprehensively analyzes the working status parameters of the solar simulation array and the telemetry data of the satellite under test, and controls the power supply control module to perform manual or autonomous dynamic scheduling of power supply resources based on the received power supply scheduling instructions or autonomous driving. The programmable relay module includes multiple programmable magnetic latching relays, which are used to branch the power supply path of the solar simulation array and complete the on / off control of all power supply paths of the satellite.

[0010] Preferred options also include: Adapter cables are used to match multiple power supply contacts to a state suitable for satellite power controllers as needed.

[0011] Preferably, the power supply control module divides the programmable relay module into M groups, each group containing N programmable magnetic latching relays. Only one programmable magnetic latching relay in each group is in the ON state at any given time, while the rest of the programmable magnetic latching relays are in the OFF state. The power supply paths of the solar simulation array are divided into N groups, and the power-up and power-down actions of each group of solar simulation array power supply paths are executed simultaneously. The power supply paths of the solar simulation array and the corresponding programmable magnetic latching relays are dynamically divided into N groups of control units. Each control unit controls the power supply resources of a single satellite by controlling N solar simulation array power supply paths and N programmable magnetic latching relays. The default grouping of the control units is that the first group of M / N power supply paths corresponds to the first satellite, the second group of M / N power supply paths corresponds to the second satellite, and so on.

[0012] Preferably, during satellite testing, the power supply control module, based on the instructions of the analysis and scheduling module, can dynamically add or remove controllable solar simulation array power supply paths and programmable magnetic latching relays from each control unit group; each solar simulation array power supply path can be added to any control unit through different on / off states of the programmable magnetic latching relays; each control unit group only controls the on / off state of the solar simulation array and programmable magnetic latching relays within the group.

[0013] Preferably, the control process in which each control unit only controls the on / off switching of the solar simulation array and the programmable magnetic latching relay within the group includes: When powering up, first connect the programmable magnetic latching relay, then power up the power supply path; when de-powering, first de-power the power supply path, then disconnect the programmable magnetic latching relay. The operating parameters and grouping parameters of the solar simulation array are sent to the analysis and scheduling module; the output current setting of the solar simulation array is based on the average power consumption of the reference satellite during the test process.

[0014] Preferably, the analysis and scheduling module supports configuring the autonomous scheduling logic of the power supply path of the solar simulation array by writing scripts; by recovering the power supply path resources of satellites with less power consumption than the preset value according to the scheduling logic, placing them into the schedulable unit, and releasing them to satellites with power consumption exceeding the preset value as needed.

[0015] Preferably, during resource recovery, the working status of the solar simulation array is determined, the power supply path in the shunt state is de-energized, the corresponding programmable magnetic latching relay is disconnected, and the power supply path resource and programmable magnetic latching relay resource of the solar simulation array are placed into the schedulable unit; during resource release, it is determined that a certain satellite needs to supplement the power supply path, the unoccupied power supply path in the schedulable unit is released to the control unit of the corresponding satellite, and then the power supply path is energized in sequence, and the programmable magnetic latching relay corresponding to the satellite is turned on.

[0016] Preferably, the autonomous scheduling logic of the analysis and scheduling module includes: The autonomous scheduling function is set to an on / off state. When the autonomous scheduling function is enabled, the analysis and scheduling unit autonomously schedules power resources. When the autonomous scheduling function is disabled, the comprehensive testing software sends power scheduling commands to schedule power resources. When it is detected that the battery pack voltage of one of the satellites being tested in parallel is lower than the set value V... L When this happens, an alarm is issued to the testers, and the autonomous scheduling mode is exited. The script configures the minimum number of power supply path resources allowed in the schedulable unit as i and the maximum number of power supply path resources allowed as j. When the number of power supply path resources in the schedulable unit is less than i, resources are actively reclaimed; when the number of power supply path resources is greater than j, resources are actively released.

[0017] Preferably, one end of the adapter cable is connected to a number of M*N power supply paths, including multiple connectors, each connector containing one power supply path; the other end is adapted to a connector that matches the power input interface of the satellite power controller, and is directly connected or connected to the power input interface of the satellite power controller via an extension cable.

[0018] A method for dynamic scheduling of power supply resources for a solar simulation array according to the present invention includes: Step S1: The power supply control module acquires the working status parameters of the solar simulation array and sends the working status parameters of the solar simulation array to the analysis and scheduling module; Step S2: The telemetry receiving module receives the telemetry data and power supply scheduling instructions from the satellite under test, and sends the telemetry data and power supply scheduling instructions to the analysis and scheduling module; Step S3: The analysis and scheduling module determines whether it is necessary to reclaim or release the power supply path of the solar simulation array based on the working status parameters of the solar simulation array, the telemetry data of the satellite under test, and the power supply scheduling instructions. Step S4: When it is determined that power supply path recovery or release is required, the analysis and scheduling module generates a power supply resource scheduling control command and sends the power supply resource scheduling control command to the power supply control module. Step S5: The power supply control module controls the power supply path of the solar simulation array and the on / off state of the programmable magnetic latching relay according to the power supply resource scheduling control command, so as to complete the dynamic scheduling of the power supply resources of the solar simulation array.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. The equipment of this invention has high utilization rate and low cost: It makes full use of the power supply capacity of each solar simulation array, avoids the problem of a large amount of power supply resources of the solar simulation array being diverted during satellite testing, and greatly reduces the power supply cost in satellite testing.

[0020] 2. The invention features a high degree of automation and strong security: By autonomously scheduling power supply resources, power resources are allocated to the satellite on demand during the testing process, greatly reducing the need for human intervention; at the same time, a multi-level alarm mode is set up to avoid testing risks caused by insufficient power supply to the satellite.

[0021] 3. The invention has high versatility and good scalability: the multiple power supply paths of the solar simulation array cabinet are decomposed into single-path configurations that can be freely configured. They can be fully compatiblely transferred to existing test cables through adapter cables, avoiding cable waste. Furthermore, as the number of hardware increases, the invention can continuously expand the number of satellites that can be tested in parallel. At the same time, the invention is applicable to mainstream power controllers such as S3R and S4R. Attached Figure Description

[0026] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0027] A dynamic scheduling system for power supply resources of a solar simulation array, comprising: The power supply control module is used to control the power supply path of the solar simulation array, as well as the on / off state of the programmable magnetic latching relay in the programmable relay module, and to send the working status parameters of the solar simulation array to the analysis and scheduling module. The telemetry receiving module is used to receive telemetry data and power supply scheduling instructions from the satellite under test, and send them to the analysis and scheduling module. The analysis and scheduling module comprehensively analyzes the working status parameters of the solar simulation array and the telemetry data of the satellite under test, and controls the power supply control module to perform manual or autonomous dynamic scheduling of power supply resources based on the received power supply scheduling instructions or autonomous driving. The programmable relay module includes multiple programmable magnetic latching relays, which are used to branch the power supply path of the solar simulation array and complete the on / off control of all power supply paths of the satellite.

[0028] like Figure 1 As shown, in one embodiment, the above system includes: Power supply control module, telemetry receiving module, analysis and scheduling module, programmable relay module and transfer cable.

[0029] The programmable relay module contains M*N programmable magnetic latching relays (where M is the number of power supply paths for the solar simulation array, generally not less than the total number of paths for the solar cell array of a single satellite, and N is the number of satellites being tested in parallel, generally M is an integer multiple of N), used to divide the M power supply paths into M*N paths, thereby realizing the on / off control of all power supply paths for N satellites. The power supply control module enables power-on and power-off control of the M-channel solar simulation array, as well as on / off control of the M*N programmable magnetic latching relays in the programmable relay module. The telemetry receiving module is used to receive satellite telemetry data parsed by the satellite integrated test software and power supply scheduling instructions sent by the software, and to send information such as power supply parameters from the analysis and scheduling module to the satellite integrated test software, communicating with the satellite integrated test software in TCP / IP mode; The analysis and scheduling module comprehensively analyzes the working status parameters of the solar simulation array and satellite telemetry data, and controls the power supply control module to perform manual or autonomous dynamic scheduling of power supply resources by receiving instructions or driving autonomously. The adapter cable will match the multiple power supply contacts to the state of being compatible with the satellite power controller as needed.

[0030] The power supply control module divides the programmable relay module into M groups, each containing N programmable magnetic latching relays. Only one relay in each group is active at any given time, while the rest are inactive, ensuring that each solar simulation array power supply path powers only one satellite. The solar simulation array power supply paths are also divided into N groups, with each group's power-up and power-down actions performed simultaneously to ensure coordinated satellite power-up and power-down actions. The module supports dynamically dividing the solar simulation array power supply paths and corresponding programmable magnetic latching relays into N control units. Each control unit controls N solar simulation array power supply paths and N programmable magnetic latching relays to control the power supply resources of a single satellite. The default grouping of the control units is as follows: the first group (M / N power supply paths) corresponds to the first satellite, the second group (M / N power supply paths) corresponds to the second satellite, and so on.

[0031] During satellite testing, the power supply control module, based on instructions from the analysis and scheduling module, can dynamically add or remove controllable solar simulation array power supply paths and programmable magnetic latching relays from each control unit group. Each power supply path can be added to any control unit through different on / off states of the programmable magnetic latching relays. Each control unit group can only control the on / off state of the solar simulation array and programmable magnetic latching relays within its group. The control process is as follows: during power-up, the programmable magnetic latching relays are first turned on, and then the power supply path is powered up; during power-down, the power supply path is first de-powered, and then the programmable magnetic latching relays are turned off to avoid switching the programmable magnetic latching relays under load. The solar simulation array operating parameters, grouping parameters, and other information are sent to the analysis and scheduling module. The output current of the solar simulation array is set with reference to the average power consumption of the satellite during testing, generally set to be equivalent to the average power of the M / N-channel solar simulation array power supply output during single-satellite testing. The analysis and scheduling module can receive information such as the working parameters and grouping parameters of the solar array sent by the power supply control module, and can receive satellite telemetry information and power supply scheduling instructions forwarded by the telemetry receiving module. It also supports configuring the autonomous scheduling logic of the solar array power supply path by writing scripts. The basic principle of the scheduling module's scheduling function is to recover power supply path resources for satellites with low power consumption according to scheduling logic, place them in the schedulable unit, and release them to satellites with higher power demand as needed. Specifically, during resource recovery, the working status of the solar simulation array is determined, the power supply path in the shunt state is de-energized, the corresponding programmable magnetic latching relay is disconnected, and the power supply path resource and programmable magnetic latching relay resource of the solar simulation array are placed in the schedulable unit. During resource release, it is determined that a satellite needs to replenish its power supply path, the available power supply path in the schedulable unit is released to the control unit of the corresponding satellite, and then the power supply path is energized and the programmable magnetic latching relay corresponding to the satellite is connected in sequence. The autonomous scheduling logic includes the following methods: (1) The autonomous scheduling function is set to on / off state. When the autonomous scheduling function is enabled, the analysis and scheduling unit performs autonomous scheduling of power supply resources. When the autonomous scheduling function is disabled, the comprehensive testing software sends power supply scheduling instructions to perform power supply resource scheduling. When it is detected that the battery pack voltage of one of the satellites being tested in parallel is lower than the set value V... L When this happens, an alarm is issued to the testers, and the autonomous scheduling mode is exited. (2) Configure the minimum number of power supply path resources allowed in the schedulable unit as i and the maximum number of power supply path resources allowed as j through the script; when the number of power supply path resources in the schedulable unit is less than i, actively reclaim the resources; when the number of power supply path resources is greater than j, actively release the resources. The power resource recovery steps of the analysis and scheduling module are as follows: Step 1: During satellite testing, when the number of power supply path resources in the schedulable unit is less than i, determine the working status of M power supply paths and perform the first round of recovery on all power supply paths in the diversion state. Step 2: After the first round of recovery, if the number of power supply path resources in the schedulable unit is greater than or equal to i, the recovery will stop; if the number of power supply path resources in the schedulable unit is still less than i, the satellite in the charging state will be selected by telemetry of the charging current of N satellites. Step 3: For satellites in charging mode, determine the battery pack voltage. When the battery pack voltage is higher than the set value V... H The second round of recovery will then be conducted, recovering one of its power supply paths when the battery pack voltage drops below the set value V. S No recycling; Step 4: After the second round of recycling, if the number of power supply path resources in the schedulable unit is greater than or equal to i, the recycling will stop; if the number of power supply path resources in the schedulable unit is still less than i, repeat steps 2 and 3 until there are no power supply paths available for recycling, and then issue an alarm to the test personnel indicating insufficient power supply resources.

[0032] The power supply resource release steps of the analysis and scheduling module are as follows: Step S1: During satellite testing, when the number of power supply path resources in the schedulable unit is greater than j, the satellite in the battery pack discharge state is selected by telemetry of the discharge current of N satellites. Step S2: Compare the battery pack voltages of the satellites in the battery pack discharge state, and release power to the satellite with the lowest voltage in the first round, releasing one power supply resource; Step S3: Repeat steps S1 and S2 until the number of power supply path resources in the schedulable unit is less than or equal to j, then stop releasing; Step S4: After repeating step S2, when none of the N satellites are in a battery discharge state and the number of power supply path resources in the schedulable unit is still greater than j, determine the satellite battery pack voltage. If the battery pack voltage is less than the set value V... C The satellite releases a power supply path; Step S5: Repeat step S4 until the battery pack voltage is less than the set value V. C When the satellite is in operation and the number of power supply path resources in the schedulable unit is still greater than j, the test personnel are prompted that the power supply resources are sufficient.

[0033] One end of the adapter cable connects to M*N power supply paths, containing multiple connectors, each containing one power supply path, and can use WS20K type connectors; the other end is adapted to a connector that matches the power input interface of the satellite power controller, which can be directly connected or connected to the power input interface of the satellite power controller via an extension cable, and can use J36A type connectors.

[0034] A method for dynamic scheduling of power supply resources for a solar simulation array includes: Step S1: The power supply control module acquires the working status parameters of the solar simulation array and sends the working status parameters of the solar simulation array to the analysis and scheduling module; Step S2: The telemetry receiving module receives the telemetry data and power supply scheduling instructions from the satellite under test, and sends the telemetry data and power supply scheduling instructions to the analysis and scheduling module; Step S3: The analysis and scheduling module determines whether it is necessary to reclaim or release the power supply path of the solar simulation array based on the working status parameters of the solar simulation array, the telemetry data of the satellite under test, and the power supply scheduling instructions. Step S4: When it is determined that power supply path recovery or release is required, the analysis and scheduling module generates a power supply resource scheduling control command and sends the power supply resource scheduling control command to the power supply control module. Step S5: The power supply control module controls the power supply path of the solar simulation array and the on / off state of the programmable magnetic latching relay according to the power supply resource scheduling control command, so as to complete the dynamic scheduling of the power supply resources of the solar simulation array.

[0035] Example 1 This invention takes a scenario of four low-Earth orbit (LEO) constellation satellites undergoing parallel testing during the assembly phase on a production line as an example. This type of satellite is equipped with an S4R power controller, containing 24 power supply paths for the solar array. During ground testing, these 24 solar simulation arrays are typically used for power supply. At the satellite assembly and testing station on the production line, the average load power consumption during single-satellite testing is approximately 1200W. Both Keysight's E4360 series solar simulation array and CETC's AV1763 series solar simulation array can achieve 300W power supply per channel. Fully equipping a single satellite with all 24 solar simulation arrays would result in a significant waste of power resources and would also place a huge burden on the mains power supply of the production line. Using the dynamic scheduling system and method for power supply resources of a solar simulation array supporting multi-satellite parallel testing provided by this invention, 24 power supply arrays can provide parallel power to four satellites. During testing, the system autonomously schedules power supply resources to meet the testing power supply needs of all satellites. It should be noted that after dynamic scheduling of power supply resources, the power distribution order of each satellite's power supply array will differ from that when all arrays are fully powered. However, this does not affect satellite testing safety, and this practice is permissible in mass production testing scenarios. The specific scheme of this embodiment is as follows: A dynamic scheduling system for power supply resources of a solar simulation array that supports parallel testing of multiple satellites includes a programmable relay module, a power supply control module, a telemetry receiving module, an analysis and scheduling module, and a transfer cable. It uses a 24-channel solar simulation array to supply power to four satellites in parallel. The solar simulation array module can use Keysight's E4360 series or CENC Instruments' AV1763 series equipment.

[0036] The programmable relay module contains 24*4 channels (where 24 represents the number of power supply paths for the solar array simulation, which is equal to the total number of paths for the solar cell array of a single satellite, allowing testing of all solar array paths for each satellite during satellite installation testing of the power supply and distribution subsystem, and 4 represents the number of satellites to be tested in parallel) of programmable magnetic latching relays, used to realize the on / off control of all power supply paths for the four satellites. The power supply control module enables power-on and power-off control of the 24-channel solar simulation array, as well as on / off control of the 24*4 programmable magnetic latching relays in the programmable relay module; The telemetry receiving module is used to receive satellite telemetry data parsed by the satellite integrated test software and power supply scheduling instructions sent by the software. It also sends information such as power supply parameters from the analysis and scheduling module to the satellite integrated test software and communicates with the software via TCP / IP. The analysis and scheduling module comprehensively analyzes the working status parameters of the solar simulation array and satellite telemetry data, and controls the power supply control module to perform manual or autonomous dynamic scheduling of power supply resources by receiving instructions or driving autonomously. The adapter cable matches the multiple power supply contacts to the desired state to adapt to the satellite power controller.

[0037] Reference Figure 2 As shown, the power supply control module divides the programmable relay module into 24 groups, each group containing 4 programmable magnetic latching relays. Only one relay in each group is active at any given time, while the rest are inactive, ensuring that each solar simulation array power supply path powers only one satellite. The solar simulation array power supply paths are divided into 4 groups, with each group's power-up and power-down actions executed simultaneously to ensure coordinated satellite power-up and power-down actions. The module supports dynamically dividing the solar simulation array power supply paths and corresponding programmable magnetic latching relays into 4 control units. Each control unit controls 4 solar simulation array power supply paths and 4 programmable magnetic latching relays to control the power supply resources of a single satellite. The default grouping of the control units is as follows: the first group of 6 power supply paths corresponds to the first satellite, the second group of 6 power supply paths corresponds to the second satellite, and so on.

[0038] During satellite testing, the power supply control module, based on instructions from the analysis and scheduling module, can dynamically add or remove controllable solar simulation array power supply paths and programmable magnetic latching relays from each control unit group. Each power supply path can be added to any control unit through different on / off states of the programmable magnetic latching relays. Each control unit group can only control the on / off state of the solar simulation array and programmable magnetic latching relays within its group. The control process is as follows: during power-up, the programmable magnetic latching relays are first turned on, and then the power supply path is powered up; during power-down, the power supply path is first de-powered, and then the programmable magnetic latching relays are turned off to avoid switching the programmable magnetic latching relays under load. The solar simulation array operating parameters, grouping parameters, and other information are sent to the analysis and scheduling module. The output current of the solar simulation array is set to 5A per channel, and the satellite bus voltage is 42V, meaning that the power output power of each channel is approximately 200W, and the power output power of the 6 channels per satellite is approximately 1200W, which is comparable to the average power consumption during the testing process, reducing energy waste. The analysis and scheduling module can receive information such as solar array working parameters and grouping parameters sent by the power supply control module, can receive satellite telemetry information and power supply scheduling instructions forwarded by the telemetry receiving module, and supports configuring the autonomous scheduling logic of the solar array power supply path by writing scripts. The basic principle of the scheduling function in the analysis and scheduling module is that, according to the scheduling logic, the power supply path resources of satellites with low power consumption are recovered and placed into the scheduling unit. As needed, they are released to satellites with higher power consumption. The specific actions are as follows: When recovering resources, the working status of the solar simulation array is determined, the power supply path in the shunt state is de-energized, and the corresponding programmable magnetic latching relay is disconnected. The power supply path resources of the solar simulation array and the programmable magnetic latching relay resources are placed into the scheduling unit. When releasing resources, it is determined that a satellite needs to replenish its power supply path. The available power supply path in the scheduling unit is released to the control unit of the corresponding satellite. Then, the power supply path is energized and the programmable magnetic latching relay corresponding to the satellite is connected in sequence. The aforementioned analysis and scheduling module's autonomous scheduling logic includes the following methods: (1) The autonomous scheduling function is set to on / off state. When the autonomous scheduling function is enabled, the analysis and scheduling unit performs autonomous scheduling of power supply resources. When the autonomous scheduling function is disabled, the comprehensive testing software sends power supply scheduling instructions to perform power supply resource scheduling. When it is detected that the battery pack voltage of one of the satellites being tested in parallel is lower than the set value V... L When this happens, an alarm is issued to the testers, and the autonomous scheduling mode is exited. (2) Configure the minimum number of power supply path resources allowed in the schedulable unit as i and the maximum number of power supply path resources allowed as j through the script; when the number of power supply path resources in the schedulable unit is less than i, actively reclaim the resources; when the number of power supply path resources is greater than j, actively release the resources. Reference Figure 3 The power resource recovery steps of the analysis and scheduling module are as follows: Step 1: During satellite testing, when the number of power supply path resources in the schedulable unit is less than i, determine the working status of M power supply paths and perform the first round of recovery on all power supply paths in the diversion state. Step 2: After the first round of recovery, if the number of power supply path resources in the schedulable unit is greater than or equal to i, the recovery will stop; if the number of power supply path resources in the schedulable unit is still less than i, the satellite in the charging state will be selected by telemetry of the charging current of N satellites. Step 3: For satellites in charging mode, determine the battery pack voltage. When the battery pack voltage is higher than the set value V... H The second round of recovery will then be conducted, recovering one of its power supply paths when the battery pack voltage drops below the set value V. S No recycling; Step 4: After the second round of recycling, if the number of power supply path resources in the schedulable unit is greater than or equal to i, the recycling will stop; if the number of power supply path resources in the schedulable unit is still less than i, repeat steps 2 and 3 until there are no power supply paths available for recycling, and then issue an alarm to the test personnel indicating insufficient power supply resources.

[0039] Reference Figure 4 The power supply resource release steps of the analysis and scheduling module are as follows: Step S1: During satellite testing, when the number of power supply path resources in the schedulable unit is greater than j, the satellite in the battery pack discharge state is selected by telemetry of the discharge current of N satellites. Step S2: Compare the battery pack voltages of the satellites in the battery pack discharge state, and release power to the satellite with the lowest voltage in the first round, releasing one power supply resource; Step S3: Repeat steps S1 and S2 until the number of power supply path resources in the schedulable unit is less than or equal to j, then stop releasing; Step S4: After repeating step S2, when none of the N satellites are in a battery discharge state and the number of power supply path resources in the schedulable unit is still greater than j, determine the satellite battery pack voltage. If the battery pack voltage is less than the set value V... C The satellite releases a power supply path; Step S5: Repeat step S4 until the battery pack voltage is less than the set value V. C When the satellite is in operation and the number of power supply path resources in the schedulable unit is still greater than j, the test personnel are prompted that the power supply resources are sufficient.

[0040] The adapter cable consists of four cables for use by four satellites. One end of each adapter cable connects to the output interface of the device's 24 power supply channels and contains 24 WS20J6TQ connectors. Each connector contains 6 contacts (3 positive and 3 negative) for one power supply channel. The other end is converted to two J36A-74TK connectors, which can be connected to the power input interface of the satellite power controller via an extension cable.

[0041] This embodiment provides a scheme for parallel power supply and dynamic scheduling of four satellites using power resources from a solar simulation array that only meets the requirements of single-satellite testing, which greatly saves testing resources. For test phases with high satellite power supply requirements, such as thermal tests, this embodiment can also be modified to provide parallel power supply and dynamic scheduling for three or two satellites using 24 power supply channels. Alternatively, power supply for multiple satellites can be achieved by expanding the number of equipment channels and solar simulation array resources.
