Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a power-off control method, device, equipment, storage medium and program product. Background Art

[0002] Conventional base stations are equipped with a variety of communication equipment (i.e., loads). During the daily operation of the loads, if the mains power is cut off, in order to extend the power supply to the main loads, the power supply to the secondary loads needs to be disconnected, that is, the secondary loads are controlled to be powered off. This process is called a primary power-off. When the battery of the base station is continuously discharged to a certain extent, in order to protect the battery from being damaged, the connection between the battery and all loads needs to be disconnected, that is, all loads are controlled to be powered off. This process is called a secondary power-off.

[0003] Super Base Station can automatically switch to satellite transmission load for communication in unusual circumstances when the ground optical transmission load fails (such as the ground communication transmission optical cable is disconnected, etc.). It is a type of base station that can ensure daily communications under unusual circumstances.

[0030] See also Figure 1 , Figure 1It is one of the flow charts of the power-off control method provided in the embodiment of the present application. In the embodiment of the present application, the power-off control method is applied to the super base station power management system, the super base station power management system is applied to the super base station, the super base station power management system includes a power management system, an intelligent switch power supply, a battery management system, a battery pack and multiple loads, the power management system is respectively connected to the battery management system and the intelligent switch power supply, the battery management system is connected to the battery pack, the battery pack is connected to the intelligent switch power supply, the intelligent switch power supply is connected to multiple loads, and the power-off control method includes steps S110 to S130, and each step is as follows: S110: Acquire the working status of the base station based on the power management system.

[0031] The base station operating state is determined based on the operating state of each load.

[0032] The existing secondary power-off control method can be implemented by the power management system of an ordinary base station, but the power management system of an ordinary base station is not suitable for a super base station. Therefore, the existing power management system needs to be modified or redesigned to obtain a super base station power management system.

[0033] In view of the power-off control strategy, equipment configuration and applicable scenarios of the super base station, the embodiments of the present invention provide four system implementation structures of the super base station power management system.

[0034] See also Figure 2 , Figure 2 This is one of the structural diagrams of the super base station power management system provided in the embodiment of the present application.

[0035] Figure 2 The structure in is applicable to the scenario where the super base station works under normal conditions. Figure 2 As shown, the super base station power management system includes a power supply system, an intelligent switching power supply, a power management system (Power Management System, PMS), an intelligent battery management system (Battery Management System, BMS), a battery pack, multiple loads, and a power environment monitoring system.

[0036] Generally, all loads in the super base station can be powered by a power supply system. The power supply system can use city power (220V / 380V AC), mobile power station, and battery pack to power the intelligent switching power supply through the AC distribution box, and power multiple loads through the intelligent switching power supply.

[0037] Among them, the intelligent switching power supply is equipped with five power modules, which are respectively connected to the ground optical transmission load ( Figure 2 in the abbreviation “optical transmission”), 5G base station load ( Figure 25G load), 4G base station load ( Figure 2 4G load), 2G base station load ( Figure 2 2G load) and narrowband satellite transmission load ( Figure 2 Satellite transmission) is an independent connection.

[0038] The battery pack is a high-energy battery pack in order to support the long-term energy supply of the super base station. The battery pack is provided with an interface for monitoring and communication for the BMS.

[0039] Among them, the power management system includes a multi-level power-off management module, a fault diagnosis and monitoring module, and a communication and telemetry module.

[0040] The intelligent battery management system includes a battery monitoring unit, a computing processing unit, and a communication and telemetry unit.

[0041] Depending on the equipment configuration of the super base station, the communication equipment load includes ground optical transmission load, 5G base station load, 4G base station load, 2G base station load and satellite transmission load.

[0042] The power management system is connected to the battery management system and the intelligent switching power supply respectively, the battery management system is connected to the battery pack, the battery pack is connected to the intelligent switching power supply, and the intelligent switching power supply is connected to multiple loads.

[0043] See also Figure 3 , Figure 3 This is the second structural diagram of the super base station power management system provided in the embodiment of the present application.

[0044] Figure 3 The structure in is suitable for the scenario where the super base station works under normal conditions and the existing battery pack needs to be modified. Figure 3 As shown, the super base station power management system includes a power supply system, an intelligent switching power supply, a power management system, a battery management interface device, an intelligent battery management system, multiple loads, existing battery packs, and a power environment monitoring system.

[0045] In order to make use of existing facilities, the existing battery packs of the base station can be modified to adapt to the application requirements of the super base station.

[0046] Specifically, it is determined whether the existing battery pack is configured with an existing interface for BMS monitoring (such as a voltage measurement point interface, a temperature sensor interface, etc.).

[0047] If the existing battery pack is not equipped with an existing interface for BMS monitoring, it needs to be modified to add necessary sensors and related interfaces, or install external measuring devices to monitor the battery pack's voltage, current, temperature, and possible single cell voltage and other information; for battery packs that lack communication interfaces, some intermediate equipment can be set up to collect sensor data and communicate with the BMS through appropriate communication protocols.

[0048] See also Figure 4 , Figure 4 This is the third structural diagram of the super base station power management system provided in the embodiment of the present application.

[0049] Figure 4 The structure in FIG. 1 is applicable to the scenario where the super base station operates under the condition of ground optical transmission load failure or normal conditions. Figure 4 As shown, the super base station power management system includes a power supply system, an intelligent switching power supply, a power management system, a battery management interface device, an intelligent battery management system, multiple loads, and a power environment monitoring system.

[0050] The power supply system can use AC power (220V / 380V AC), mobile power stations, through voltage stabilizers, AC distribution boxes, rectifiers, etc., together with battery packs, solar power generation or wind power generation, through DC distribution panels to power the intelligent switching power supply, and power multiple loads through the intelligent switching power supply.

[0051] Among them, the super base station works under the condition of ground optical transmission load failure. The intelligent switching power supply is equipped with five power modules, and the five power modules are independently connected to the ground optical transmission load, 5G base station load, 4G base station load, 2G base station load and narrowband satellite transmission load.

[0052] See also Figure 5 , Figure 5 This is the fourth structural diagram of the super base station power management system provided in the embodiment of the present application.

[0053] With respect to the current working conditions of the super base station with one power-off and two power-offs, the solution of the present application allows for dynamic adjustment of the preset power-off strategy scenario.

[0054] like Figure 5 As shown, the super base station power management system includes a power supply system, an intelligent switching power supply, a power management system, a battery management interface device, an intelligent battery management system, multiple loads, a battery pack, and a power environment monitoring system.

[0055] Assuming that the super base station works under the existing primary power-off and secondary power-off working conditions, the intelligent switching power supply is equipped with three power modules, which are respectively connected to the ground optical transmission load, 5G base station load, 4G base station load, 2G base station load and narrowband satellite transmission.

[0056] Among them, the 2G base station load, 4G base station load, and 5G base station load are connected to power module three; in the traditional one-time power-off process, the wireless communication equipment, that is, power module three, is usually powered off, and the second power-off process is usually to power off the transmission equipment. The difference of this application is that the power management system can dynamically adjust the power module one and power module two of the second power-off according to the strategy. This system structure is not only applicable to super base stations, but also to the power-off management of ordinary base stations in remote areas.

[0057] Generally, the base station working state includes a fault state (ie, the super base station works under a fault condition, and part of the load fails) and a non-fault state (ie, the super base station works under a normal condition, and no load fails).

[0058] Specifically, based on the power management system in the super base station power management system, the base station working state of the super base station and the load working state of each load of the super base station can be acquired in real time.

[0059] S120: Acquire state of charge information of the battery pack based on the battery management system.

[0060] Generally, all loads in a super base station can be powered by a power supply system, which can provide the loads with city power, new energy power sources (such as solar power generation, wind power generation, hydrogen power generation), battery packs, etc.

[0061] In this embodiment, the super base station power management system may obtain the charge state information of the battery pack based on the battery management system.

[0062] S130: Based on the power management system, according to the base station working state and charge state information, control at least one load to power off through an intelligent switch power supply.

[0063] After obtaining the base station working state, load working state and charge state information, the super base station power management system can control at least one load to power off through an intelligent switch power supply based on the base station working state, load working state and charge state information.

[0064] The power-off control method provided in the embodiment of the present application is applied to the power management system of a super base station. The power management system of the super base station includes a power management system, an intelligent switch power supply, a battery management system, a battery pack and multiple loads. The power management system is respectively connected to the battery management system and the intelligent switch power supply, the battery management system is connected to the battery pack, the battery pack is connected to the intelligent switch power supply, and the intelligent switch power supply is connected to multiple loads. The method includes: based on the power management system, obtaining the working state of the base station; the working state of the base station is determined based on the working state of each load; based on the battery management system, obtaining the charge state information of the battery pack; based on the power management system, according to the working state of the base station and the charge state information, controlling at least one load to power off through the intelligent switch power supply. Through the above method, according to the working state of the base station and the charge state information, at least one load is controlled to power off through the intelligent switch power supply. In the process of load power-off control, the base station working state of the super base station and the charge state information of the battery pack are simultaneously referred to for dynamic decision-making, which can provide dynamic and refined load power-off control to meet the management requirements of load power-off in the super base station.

[0065] In some embodiments, the state of charge information includes an SOC value of a battery pack, and the intelligent switching power supply includes at least one power module, and the power module is used to control power-off of a load.

[0066] Based on a power management system, according to the working state and charge state information of the base station, at least one load is controlled to be powered off through an intelligent switching power supply, including: determining a target power-off strategy group from a plurality of preset power-off strategy groups according to the working state of the base station; each preset power-off strategy group includes a plurality of preset power-off strategies; comparing the SOC value with a plurality of preset thresholds respectively to obtain a comparison result, and determining a target power-off strategy from a plurality of preset power-off strategies of the target power-off strategy group based on the comparison result; based on the power management system, according to the target power-off strategy, at least one load is controlled to be powered off through an intelligent switching power supply.

[0067] See also Figure 6 , Figure 6 It is a structural diagram of a battery management system provided in an embodiment of the present application.

[0068] The key to the battery management system (i.e., intelligent battery management system) to monitor battery pack parameters lies in its integrated sensors and control algorithms. The sensors and control algorithms work together to monitor the status of the battery pack in real time and perform intelligent management based on the operating status and capacity of the battery pack.

[0069] Specifically, Figure 6 As shown, the battery management system includes a battery monitoring unit, a computing and processing unit, and a communication and telemetry unit. The specific functions of each unit are as follows: (1) Battery monitoring unit: The battery monitoring unit monitors and obtains the voltage, current, temperature and SOC (State of Charge) value of the battery pack through the interface between the battery pack and the battery pack.

[0070] The battery management system can monitor the voltage of the battery pack.

[0071] Specifically, the battery management system monitors the battery pack voltage in real time through a voltage sensor connected to each battery pack or battery pack. The battery pack voltage is calculated using the following formula: ; Where: OCV is the open circuit voltage of the battery pack, which can be measured when the battery is at rest; I is the current drawn from the battery pack; R internal is the internal resistance of the battery pack; R cables is the resistance in the circuit and the cable connection.

[0072] The battery management system can monitor the current of the battery pack.

[0073] Specifically, the battery management system monitors the charging current and discharging current through current sensors installed in the battery pack loop to evaluate the real-time power consumption and remaining capacity of the battery pack.

[0074] The battery management system can monitor the temperature of the battery pack.

[0075] Specifically, temperature sensors are deployed at key locations of the battery pack to monitor the temperature of the battery pack and prevent damage to the battery pack due to excessive temperature.

[0076] The battery management system needs to be able to directly connect to the voltage sensors and current sensors of the existing battery pack. If these sensors are not pre-installed in the battery pack, they need to be installed additionally. For temperature monitoring of the battery pack, a temperature sensor needs to be installed inside or on the surface of the battery pack.

[0077] (2) Computing processing unit: The computing processing unit includes a microcontroller unit and a storage unit, and can run a control algorithm to estimate the SOC value of the battery pack and perform a battery pack SOH (State of Health) evaluation.

[0078] Among them, the microcontroller unit is the core processing unit, which is used to process data from the battery monitoring unit and run the SOC estimation algorithm.

[0079] The storage unit is used to store characteristic data, discharge curves, historical monitoring data, and power-off strategy parameters of the battery pack.

[0080] The control algorithm is implemented at the software level, which can dynamically adjust the load power supply status according to the real-time SOC value of the battery pack and the preset power-off parameter level.

[0081] Specifically, battery packs include lead-acid battery packs and lithium battery packs. In the estimation of SOC value, for lead-acid battery packs, the SOC value of the battery pack can be estimated based on the approximate linear relationship between voltage and SOC value, combined with the discharge curve; for lithium battery packs, complex algorithms are required, such as the coulomb counting method, combined with the open circuit voltage method, to accurately calculate the SOC value of the battery pack by comprehensively considering parameters such as voltage, current, and temperature.

[0082] Specifically, for a lead-acid battery pack, the SOC value of the lead-acid battery pack (denoted as SOC Pb ) is calculated as follows: ; Wherein, OCV represents the open circuit voltage of the battery pack; V empty V is the voltage of the battery pack when it is discharged; full The voltage when the battery pack is fully charged.

[0083] Specifically, the characteristics of lithium battery packs are different from those of lead-acid battery packs. The relationship between the voltage and SOC value of a lithium battery pack is not linear, and the state of charge information of the lithium battery pack cannot be accurately determined simply by detecting the voltage. Therefore, it is necessary to precisely control the charging and discharging of the battery pack, obtain the voltage, current, and temperature of the lithium battery pack, and use an advanced state of charge algorithm to determine the state of charge of the lithium battery pack.

[0084] The voltage calculation formula of lithium battery pack is as follows: ; Where OCV is the open circuit voltage of the battery pack, which can be measured when the battery is at rest; I is the current drawn from the battery pack; R internal is the internal resistance of the battery pack; R cables is the resistance of the circuit and the cable connection; ΔV empty It is the voltage of the battery pack when it is discharged, taking into account the effect of temperature on voltage.

[0085] The calculation of the SOC value of a lithium battery pack is relatively complex because it not only depends on the voltage, but is also affected by many other variables, such as the battery pack temperature, the number of charge and discharge cycles, etc. Moreover, the relationship between the voltage and the SOC value of a lithium battery pack is usually nonlinear, and experiments are required to obtain the detailed relationship between the SOC value and the voltage.

[0086] Based on this, in this embodiment, the library total count method is used to estimate the SOC value of the lithium battery pack by combining the changes in voltage and internal resistance. The SOC value of the lithium battery pack (denoted as SOC Li ) is calculated as follows: ; Among them, SOC inital The initial SOC value of the battery pack; Q total is the total capacity of the battery pack, usually expressed in ampere-hours; I is the current drawn from the battery pack.

[0087] In practical applications, in order to accurately estimate the SOC value of the battery pack, the battery management system usually combines the historical data, empirical formulas and real-time monitoring data of the battery pack, and performs calibration and optimization through machine learning or other advanced algorithms.

[0088] The battery management system can evaluate the health status of the battery pack and obtain the SOH value of the battery pack by long-term tracking of parameters such as the battery pack's charge and discharge cycles, capacity decay, and internal resistance changes.

[0089] Among them, the SOH value of the lead-acid battery pack (denoted as SOH Pb ) is calculated as follows: ; Among them, SG measured SG is the current specific gravity of the electrolyte in the battery pack; full It is the specific gravity of the electrolyte when the battery pack is fully charged; SG exhausted It is the specific gravity of the electrolyte when the battery pack is depleted.

[0090] Optionally, the SOH value of a lithium battery pack can be estimated by measuring the internal resistance that increases over time. As an indicator of battery pack aging, the SOH value of a lithium battery pack (denoted as SOH Li ) is calculated as follows: ; Among them, IR current is the internal resistance of the battery pack currently measured; IR new is the internal resistance of a new battery pack (i.e., the battery pack has never been used); IR fail is the internal resistance of the battery pack when it fails.

[0091] (3) Communication and telemetry unit: The battery management system can communicate with the power management system through the communication and telemetry unit, and send the state of charge information or other parameter information of the battery pack to the power management system so that the power management system can adjust the load or execute the preset power-off strategy according to the state of charge information of the battery pack. The communication between the battery management system and the power management system can be realized through a standard communication interface, such as an RS485 interface, a CAN bus interface or an Ethernet interface.

[0092] In response to the problem that the existing secondary power-off control method is not suitable for the refined management of super base stations, this application proposes a refined multi-level power-off control method, so that the super base station can accurately control the power-off of the load under different working conditions, thereby maximizing the use time of the super base station battery pack for critical loads.

[0093] Specifically, the present application classifies and grades the loads set in the base station in advance, and designs a multi-level power-off strategy based on the load level and the working status of the base station; in actual application, it is necessary to dynamically select and determine the preset power-off strategy according to the current working status of the base station and the real-time charge status information of the battery pack, execute the preset power-off strategy, and control the power-off of the load.

[0094] In this embodiment, the selection and execution of the preset power-off strategy is intended to maximize the power supply time of the battery pack to the critical load to ensure communication.

[0095] Specifically, the load of the super base station generally includes ground optical transmission load, 5G base station load, 4G base station load, 2G base station load and satellite transmission load, and the working state of the super base station includes fault state and non-fault state.

[0096] If the working state of the base station is a fault state, and it is determined based on the working state of the load that the ground optical transmission load has a fault, the preset first power-off strategy group is used for power-off control. The first power-off strategy group includes multiple preset power-off strategies. The preset power-off strategies include the first power-off strategy, the second power-off strategy, the third power-off strategy, the fourth power-off strategy, and the fifth power-off strategy, a total of 5 types: the first power-off strategy is to power off the satellite transmission load, and the power-off level is L0 (the power-off level is L0, which means that the super base station enters the emergency mode. In the emergency mode, if the first power-off strategy is not executed, the super base station generally only provides the most basic communication services, and only retains the satellite transmission load for communication transmission. The 5G base station load, the 4G base station load, the 2G base station load and the ground optical transmission load are all powered off. If the first power-off strategy is executed, the satellite transmission load used for communication will be powered off); the second power-off strategy is to power off the 2G base station load, and the power-off level is L1 (if the second power-off strategy is not executed , the 2G base station load can continue to be used for communication transmission. If the second power-off strategy is executed, the 2G base station load will be powered off); the third power-off strategy is to power off the 4G base station load, and the power-off level is L2 (if the third power-off strategy is not executed, the 4G base station load can continue to be used for communication transmission. If the third power-off strategy is executed, the 4G base station load will be powered off); the fourth power-off strategy is to power off the 5G base station load, and the power-off level is L3 (if the fourth power-off strategy is not executed, the 5G base station load can continue to be used for communication transmission. If the fourth power-off strategy is executed, the 5G base station load will be powered off, reducing the power supply priority of the 4G base station load); the fifth power-off strategy is to power off the ground optical transmission load, and the power-off level is L4 (if the fifth power-off strategy is not executed, the ground optical transmission load can continue to be used for communication transmission. If the fifth power-off strategy is executed, the ground optical transmission load will be powered off, and the 5G base station load, 4G base station load, and 2G base station load can continue to be used for communication transmission).

[0097] If the working state of the base station is a fault state, and it is determined based on the working state of the load that the satellite transmission load has a fault, the preset second power-off strategy group is used for power-off control, and the second power-off strategy group includes multiple preset power-off strategies, and the preset power-off strategies include the first power-off strategy, the second power-off strategy, the third power-off strategy, the fourth power-off strategy, and the fifth power-off strategy, a total of 5 types: the first power-off strategy is to power off the ground optical transmission load, and the power-off level is L0 (the power-off level is L0, which means that the super base station enters the emergency mode. In the emergency mode, if the first power-off strategy is not executed, the super base station generally only provides the most basic communication services, and only retains the ground optical transmission load for communication transmission. The 5G base station load, the 4G base station load, the 2G base station load and the satellite transmission load are all powered off. If the first power-off strategy is executed, the ground optical transmission load last used for communication will be powered off); the second power-off strategy is to power off the 5G base station load, and the power-off level is L1 (if the second power-off strategy is not executed, the 5G base station load The load can continue to be used for communication transmission. If the second power-off strategy is executed, the 5G base station load will be powered off); the third power-off strategy is to power off the 4G base station load, and the power-off level is L2 (if the third power-off strategy is not executed, the 4G base station load can continue to be used for communication transmission. If the third power-off strategy is executed, the 4G base station load will be powered off); the fourth power-off strategy is to power off the 2G base station load, and the power-off level is L3 (if the fourth power-off strategy is not executed, the 2G base station load can continue to be used for communication transmission. If the fourth power-off strategy is executed, the 2G base station load will be powered off); the fifth power-off strategy is to power off the satellite transmission load, and the terrestrial optical transmission load, 5G base station load, 4G base station load, and 2G base station load will not be powered off, and the power-off level is L4 (if the fifth power-off strategy is not executed, the satellite transmission load can continue to be used for communication transmission. If the fifth power-off strategy is executed, the satellite transmission load will be powered off, and the 5G base station load, 4G base station load, and 2G base station load can continue to be used for communication transmission).

[0098] If the working state of the base station is not a fault state, the preset third power-off strategy group is used for power-off control. The third power-off strategy group includes multiple preset power-off strategies. The preset power-off strategies include the first power-off strategy, the second power-off strategy, the third power-off strategy, the fourth power-off strategy, and the fifth power-off strategy, a total of 5 types: the first power-off strategy is to power off the ground optical transmission load, and the power-off level is L0 (the power-off level is L0, which means that the super base station enters the emergency mode. In the emergency mode, if the first power-off strategy is not executed, the super base station generally only provides the most basic communication services, and only retains the ground optical transmission load for communication transmission. The 5G base station load, 4G base station load, 2G base station load and satellite transmission load are all powered off. If the first power-off strategy is executed, the ground optical transmission load used for communication will be powered off); the second power-off strategy is to power off the 5G base station load, and the power-off level is L1 (if the second power-off strategy is not executed, the 5G base station load can continue to be used for communication transmission, If the second power-off strategy is executed, the 5G base station load will be powered off); the third power-off strategy is to power off the 4G base station load, and the power-off level is L2 (if the third power-off strategy is not executed, the 4G base station load can continue to be used for communication transmission. If the third power-off strategy is executed, the 4G base station load will be powered off); the fourth power-off strategy is to power off the 2G base station load, and the power-off level is L3 (if the fourth power-off strategy is not executed, the 2G base station load can continue to be used for communication transmission.

If the fifth power-off strategy is executed, the satellite transmission load will be powered off, and the 5G base station load, 4G base station load, and 2G base station load can continue to be used for communication transmission).

[0099] Specifically, based on the battery management system, the real-time SOC value of the battery pack can be obtained; based on the power management system, the working status of the base station can be obtained, and the working status of the base station is determined by the load working status of each load (that is, the fault condition of each load). When there is a faulty load in the base station, the working status of the base station is a faulty state, and when there is no faulty load in the base station, the working status of the base station is a non-faulty state; according to the working status of the base station, a target power-off strategy group can be determined from multiple preset power-off strategy groups, wherein each preset power-off strategy group includes multiple preset power-off strategies.

[0100] Further, the SOC value is compared with a plurality of preset thresholds respectively to obtain comparison results, and a target power-off strategy is determined from a plurality of preset power-off strategies in the target power-off strategy group based on the comparison results.

[0101] The battery monitoring unit of the battery management system monitors the voltage, current, temperature and SOC value of the battery pack through the interface between the battery pack and the battery pack. The calculation processing unit can determine the SOC value of the battery pack based on the relevant information of the battery pack obtained by the battery monitoring unit, and pre-defines multiple power-off parameter levels from L4 to L0 based on the SOC value. Based on the power-off parameter levels, the battery management system sends commands to the power module to be adjusted corresponding to the intelligent switching power supply through the control interface according to the battery status (such as voltage, current, temperature), controls the power module to be adjusted to be turned on or off, thereby controlling the power supply status of the load; the communication and telemetry module is responsible for communication and information transmission with the power management system. The battery management system monitors the voltage, current, temperature and SOC value of the battery pack through the interface between the battery pack and communicates with the main control unit of the power management system through the communication interface to transmit battery status information and receive control commands.

[0102] Optionally, in actual deployment, the battery management system may be partially deployed on the power environment monitoring system, or may be deployed separately to communicate with the power management system.

[0103] Multiple preset power-off strategies can define L4~L0 multi-level power-off parameter levels according to the SOC value of the battery pack and the priority of the load, as shown in Table 1, which illustrates the L4~L0 multi-level power-off parameter levels: Table 1

[0104] Specifically, if the SOC value is less than the first preset threshold, the power-off level is determined to be L0, and the target power-off strategy is the first power-off strategy; if the SOC value is greater than or equal to the first preset threshold and less than the second preset threshold, the power-off level is determined to be L1, and the target power-off strategy is the second power-off strategy; if the SOC value is greater than or equal to the second preset threshold and less than the third preset threshold, the power-off level is determined to be L2, and the target power-off strategy is the third power-off strategy; if the SOC value is greater than or equal to the third preset threshold and less than the fourth preset threshold, the power-off level is determined to be L4, and the target power-off strategy is the fourth power-off strategy; if the SOC value is greater than or equal to the fourth preset threshold and less than the fifth preset threshold, the power-off level is determined to be L5, and the target power-off strategy is the fifth power-off strategy.

[0105] Corresponding to Table 1, the first preset threshold is 10%, the second preset threshold is 25%, the third preset threshold is 50%, the fourth preset threshold is 75%, and the fifth preset threshold is 100%.

[0106] It can be understood that the settings of the first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold and the fifth preset threshold can be adjusted according to actual needs.

[0107] After the target power-off strategy is determined, the load to be powered off may be determined based on the target power-off strategy.

[0108] For example, if the working state of the base station is a fault state and the ground optical transmission load fails, the SOC value is greater than or equal to the fourth preset threshold and less than the fifth preset threshold, then the target power-off strategy is the fifth power-off strategy, and the fifth power-off strategy is to power off the ground optical transmission load. The power-off level is L4, and at this time the load to be powered off is the ground optical transmission load.

[0109] Furthermore, based on the power management system and according to the target power-off strategy, at least one load is controlled to be powered off through an intelligent switching power supply.

[0110] The power management system includes a multi-level power-off management module, a fault diagnosis and monitoring module, and a communication and telemetry module. Its main functions are to pre-set multiple power-off levels and power-off strategies, and update and monitor the power-off levels based on the information provided by the diagnosis and monitoring module; the power management system integrates fault detection functions, especially fault detection for key loads (such as ground optical transmission loads and satellite transmission loads). Once a load fault is detected, the power management system will automatically update the power-off level and the corresponding preset power-off strategy based on the working status of the base station and the fault condition of the load; the power management system can communicate with the battery management system to obtain the parameter information of the battery pack, and send commands to the corresponding power module of the intelligent switching power supply through the control interface based on the status of the battery pack (such as voltage, current, and temperature) to control the power supply status of the load.

[0111] Optionally, the intelligent switching power supply includes at least one power module; one power module can be connected to multiple loads respectively, or one power module is only connected to one load; the power module is used to control the power-off of the load; after determining the target power-off strategy and determining the load to be powered off, determine the power module to be adjusted according to the target power-off strategy, and control the opening or closing of the power module to be adjusted, change the power supply switch of the load to be powered off from closed to open, cut off the connection between the power module and the load to be powered off, stop supplying power to the load to be powered off, thereby controlling the power-off of the load to be powered off.

[0112] It should be noted that, in this embodiment, in order to implement the above-mentioned multi-level power-off strategy in the super base station, the connection design between the intelligent switching power supply and the load needs to be able to flexibly adapt to different operating states and power-off requirements.

[0113] Specifically, the intelligent switching power supply can be provided with multiple intelligent control interfaces, and each power module should be equipped with an intelligent control interface so that the battery management system can send specific control commands to enable or disable specific loads according to actual conditions.

[0114] Preferably, the intelligent switching power supply adopts a modular design: each power module uses an efficient DC / DC converter (DC-DC converter), each power module can work independently, and supports communication and collaborative work with other modules in the system.

[0115] Preferably, the intelligent switching power supply can be designed with multi-channel output according to the preset power-off levels of different power-off strategies, and each power module output corresponds to a different load level (L4~L0).

[0116] The intelligent switching power supply should support priority configuration. The multi-level power-off management module of the power management system can control the intelligent switching power supply to dynamically adjust the power supply priority of each load according to the current working status of the base station and the preset power-off strategy.

[0117] In some embodiments, a power module is used to control power off of a load.

[0118] Based on a power management system, according to a target power-off strategy, at least one load is controlled to be powered off through an intelligent switching power supply, including: based on the target power-off strategy, determining a power module to be adjusted in the intelligent switching power supply; the number of the power modules to be adjusted is at least one; based on the power management system, according to the target power-off strategy, controlling each power module to be adjusted to be turned on or off, thereby controlling at least one load to be powered off.

[0119] Specifically, for example Figure 2 As shown, one power module is connected to only one load, that is, one power module is only used to control the power-off of one load.

[0120] After determining the target power-off strategy, a power module to be adjusted in the intelligent switching power supply may be determined based on the target power-off strategy, and the number of the power module to be adjusted is at least one.

[0121] Furthermore, based on the power management system, each power module to be adjusted is controlled to be turned on or off, thereby controlling multiple loads to be powered off.

[0122] In some embodiments, a power module is used to control at least one load to power off.

[0123] Based on a power management system, according to a target power-off strategy, at least one load is controlled to be powered off through an intelligent switching power supply, including: based on the target power-off strategy, determining a corresponding power module to be adjusted in the intelligent switching power supply; one target power-off strategy corresponds to one power module to be adjusted; based on the power management system, controlling the power module to be adjusted corresponding to the target power-off strategy to be turned on or off, thereby controlling at least one load to be powered off.

[0124] Specifically, for example Figure 5As shown, one power module can be connected to multiple loads at the same time, that is, one power module can be used to control the power-off of multiple loads at the same time.

[0125] After the target power-off strategy is determined, the corresponding power module to be adjusted in the intelligent switching power supply can be determined based on the target power-off strategy, and one target power-off strategy corresponds to one power module to be adjusted.

[0126] Furthermore, based on the power management system, the power module to be adjusted corresponding to the target power-off strategy is controlled to be turned on or off, thereby controlling the power-off of multiple loads.

[0127] In some embodiments, the load includes ground optical transmission load, 5G base station load, 4G base station load, 2G base station load and satellite transmission load, the base station working state includes a fault state, and the preset power-off strategy group includes a first power-off strategy group.

[0128] According to the working status of the base station, a target power-off strategy group is determined from multiple preset power-off strategy groups, including: if the working status of the base station is a fault state and the ground optical transmission load fails, the target power-off strategy group is determined to be the first power-off strategy group; wherein the first power-off strategy group includes multiple preset power-off strategies, and the preset power-off strategies include the first power-off strategy, the second power-off strategy, the third power-off strategy, the fourth power-off strategy, and the fifth power-off strategy; the first power-off strategy is to power off the satellite transmission load; the second power-off strategy is to power off the 2G base station load; the third power-off strategy is to power off the 4G base station load; the fourth power-off strategy is to power off the 5G base station load; and the fifth power-off strategy is to power off the ground optical transmission load.

[0129] In some embodiments, the load includes ground optical transmission load, 5G base station load, 4G base station load, 2G base station load and satellite transmission load, the base station working state includes a fault state, and the preset power-off strategy group includes a second power-off strategy group.

[0130] According to the working status of the base station, a target power-off strategy group is determined from multiple preset power-off strategy groups, including: if the working status of the base station is a fault state and the satellite transmission load fails, the target power-off strategy group is determined to be the second power-off strategy group; wherein the second power-off strategy group includes multiple preset power-off strategies, and the preset power-off strategies include the first power-off strategy, the second power-off strategy, the third power-off strategy, the fourth power-off strategy, and the fifth power-off strategy; the first power-off strategy is to power off the ground optical transmission load; the second power-off strategy is to power off the 5G base station load; the third power-off strategy is to power off the 4G base station load; the fourth power-off strategy is to power off the 2G base station load; the fifth power-off strategy is to power off the satellite transmission load, and the ground optical transmission load, 5G base station load, 4G base station load, and 2G base station load are not powered off.

[0131] In some embodiments, the load includes ground optical transmission load, 5G base station load, 4G base station load, 2G base station load and satellite transmission load, the base station working state includes a non-fault state, and the preset power-off strategy group includes a third power-off strategy group.

[0132] According to the working status of the base station, a target power-off strategy group is determined from multiple preset power-off strategy groups, including: if the working status of the base station is a non-fault state, the target power-off strategy group is determined to be the third power-off strategy group; wherein the third power-off strategy group includes multiple preset power-off strategies, and the preset power-off strategies include the first power-off strategy, the second power-off strategy, the third power-off strategy, the fourth power-off strategy, and the fifth power-off strategy; the first power-off strategy is to power off the ground optical transmission load; the second power-off strategy is to power off the 5G base station load; the third power-off strategy is to power off the 4G base station load; the fourth power-off strategy is to power off the 2G base station load; the fifth power-off strategy is to power off the satellite transmission load, and the ground optical transmission load, 5G base station load, 4G base station load, and 2G base station load are not powered off.

[0133] In some embodiments, the SOC value is compared with multiple preset thresholds respectively to obtain comparison results, and the target power-off strategy is determined from multiple preset power-off strategies of the target power-off strategy group based on the comparison results, including: if the SOC value is less than the first preset threshold, the target power-off strategy is determined to be the first power-off strategy; if the SOC value is greater than or equal to the first preset threshold and less than the second preset threshold, the target power-off strategy is determined to be the second power-off strategy; if the SOC value is greater than or equal to the second preset threshold and less than the third preset threshold, the target power-off strategy is determined to be the third power-off strategy; if the SOC value is greater than or equal to the third preset threshold and less than the fourth preset threshold, the target power-off strategy is determined to be the fourth power-off strategy; if the SOC value is greater than or equal to the fourth preset threshold and less than the fifth preset threshold, the target power-off strategy is determined to be the fifth power-off strategy.

[0134] In order to facilitate understanding of the above power supply method, this application also provides a specific example of a power-off control method. Figure 7 , Figure 7 This is the second flow chart of the power-off control method provided in the embodiment of the present application. Figure 7 The power-off control method shown is based on Figures 2 to 5 Any system structure in the implementation.

[0135] like Figure 7 As shown, the specific process of the power-off control method is as follows: (1) Preset multi-level power-off strategies.

[0136] (2) Fault monitoring and power-off level update.

[0137] The fault diagnosis and monitoring module integrated in the power management system monitors and obtains the working status of the base station and the fault conditions of the load in real time, and determines whether the base station is in a normal working state (non-fault state) or a fault state. If it is found that the working state is inconsistent with the preset power-off level and the preset power-off strategy, the power management system will automatically update the power-off level and the power-off strategy to adapt to the current working scenario.

[0138] (3) Monitor the SOC value of the battery pack in real time and compare the SOC value with multiple preset thresholds. When the SOC value drops to a preset threshold, generate a power-off command.

[0139] (4) Based on the power-off instruction generated by the multi-level power-off management module of the power management system, the central control unit and the intelligent switch module of the control system execute the power-off operation to control the power-off of the load to be powered off.

[0140] (5) As the SOC value continues to decrease, the system will gradually execute higher-level preset power-off strategies until power is restored.

[0141] (6) When the battery pack is charged again and the SOC value returns to a safe level, the power management system instructs the control system to start the power restoration process.

[0142] Now combined Figure 2 The system structure of the multi-level power-off process is further explained, taking the scenario where the super base station is currently working under normal conditions as an example: Step 1: Preset multiple levels of initial power-off levels, as shown in Table 2.

[0143] Table 2

[0144] Among them, the super base station is currently working under normal conditions, and power modules one to five of the intelligent switching power supply are all in a closed state.

[0145] Step 2: Fault monitoring and power-off level update.

[0146] The fault diagnosis and monitoring module integrated in the power management system monitors the working status and load fault conditions of the base station in real time. If the working status of the base station is monitored to be a faulty state and the ground optical transmission load fails, the power-off level and power-off strategy are updated. The updated power-off level is shown in Table 3.

[0147] Table 3

[0148] Step 3: Monitor the SOC value of the battery pack in real time, and compare the SOC value with multiple preset thresholds. When the SOC value drops to a preset threshold, generate a power-off instruction. Taking the multi-level power-off parameter levels shown in Table 1 as an example, if the AC power is interrupted and the battery management system detects that the SOC value of the battery pack is 60%, then the power-off level corresponds to the L3 level (SOC value is between 50%-75%) according to the power-off parameter levels in Table 1, and the power-off level instruction L3 will be generated and issued.

[0149] Step 4: According to the multi-level power-off management module of the power management system, a power-off command is issued, and the central control unit and the intelligent switch module of the control system execute the corresponding power-off operation. At this time, the power supply status of the intelligent switch is shown in Table 4.

[0150] Table 4

[0151] Step 5: As the SOC value of the battery pack further decreases, the system will gradually execute higher-level preset power-off strategies. If the battery management system detects that the SOC value of the battery pack is 30%, and compares the power-off parameter level in Table 1, the power-off level corresponds to level L3 (SOC value is between 25% and 50%), then a power-off level instruction L2 will be generated and issued, and the central control unit and the intelligent switch module will execute the corresponding power-off operation. At this time, the power supply status of the intelligent switch is shown in Table 5.

[0152] Table 5

[0153] Step 6: When the battery pack is charged again and the SOC value returns to a safe level, the power management system instructs the control system to start the power restoration process.

[0154] The power-off control method provided in this embodiment improves the battery management system, making it feasible to provide more refined power-off control for the super base station. At the same time, through the intelligent and advanced detection and diagnosis system, it automatically identifies load fault conditions and executes corresponding power-off strategies, which can meet the use scenarios of super base stations with different working states and different fault loads, and can maximize the use time of super base station battery packs for critical loads, providing more refined load power-off management.

[0155] The present application also provides a power-off control device. Figure 8 , Figure 8 8 is a schematic diagram of the structure of the power-off control device provided in the embodiment of the present application. In the embodiment of the present application, the power-off control device includes a first acquisition module 810 , a second acquisition module 820 and a power-off control module 830 .

[0156] The first acquisition module 810 is used to acquire the working status of the base station based on the power management system.

[0157] The base station operating state is determined based on the operating state of each load.

[0158] The second acquisition module 820 is used to acquire the state of charge information of the battery pack based on the battery management system.
