Description

Technical Field

[0001] This application relates to the field of power distribution, specifically to a host identification method and power distribution equipment. Background Technology

[0002] With the increasing household electricity load, power distribution systems have gradually expanded from single distribution devices to interconnected systems, ensuring that each load has a corresponding distribution branch for connection and thus enabling power supply control for that load. Typically, multiple distribution devices in a power distribution system connect to the various distribution branches of a main distribution device, i.e., they are connected in a master-slave cascade manner. This main distribution device acts as a control unit, managing all the distribution devices in the system. However, identifying the main distribution device from among the master-slave cascaded devices remains a pressing technical problem. Summary of the Invention

[0003] In view of the above, it is necessary to provide a host identification method and power distribution equipment to solve the technical problem of identifying the dispatch host from the power distribution system.

[0004] In a first aspect, this application provides a host identification method, which is executed on any power distribution device in a power distribution system. The method includes: disconnecting all power distribution branches in response to a received host verification command; obtaining device status information of other power distribution devices in the power distribution system, and confirming the mains connection status of the corresponding power distribution device based on the device status information, wherein the mains connection status includes the mains power failure status; and configuring the current power distribution device as a dispatch host when it is confirmed that all other power distribution devices in the power distribution system are in the mains power failure status, so as to perform energy dispatch control on other power distribution devices.

[0005] In this embodiment, after disconnecting all power distribution branches connected to the current power distribution equipment, the mains connection status of the corresponding power distribution equipment is confirmed based on the equipment status information of other power distribution equipment in the power distribution system. When it is confirmed that all other power distribution equipment in the power distribution system is in the mains power failure state, the current power distribution equipment is configured as the dispatch host. In this way, the current power distribution equipment can be confirmed as the dispatch host through the mains power failure status of other power distribution equipment in the power distribution system, which simplifies the host identification process, improves the host identification accuracy, and facilitates the control of other energy storage devices in the power distribution system through the dispatch host.

[0006] In some embodiments of this application, when configuring the current power distribution equipment as the dispatch host, the method further includes: returning a verification success instruction to the sender of the host verification instruction; and / or outputting a verification success instruction to other power distribution equipment in the power distribution system; the verification success instruction is used to indicate that the current power distribution equipment is the dispatch host; the verification success instruction carries the equipment identification information of the current power distribution equipment.

[0007] In this embodiment, when the current power distribution device is configured as the dispatch host, a successful verification instruction is returned to the sender of the host verification instruction. This notifies the sender of the dispatch host's identity, facilitating user control of the power distribution system through the dispatch host. A successful verification instruction is also output to other power distribution devices in the system. By indicating that the current power distribution device is the dispatch host, other power distribution devices can easily verify the dispatch host's identity when receiving control instructions from the dispatch host.

[0008] In some embodiments of this application, the device status information includes communication status; obtaining the device status information of other power distribution devices in the power distribution system and confirming the mains connection status of the corresponding power distribution device based on the device status information includes: after disconnecting all power distribution branches for a preset time, obtaining the communication status of other power distribution devices in the power distribution system; the communication status includes online communication status and offline communication status; if the power distribution device is in online communication status, it is confirmed that the corresponding power distribution device is not in a mains power failure state; if the power distribution device is in offline communication status, it is confirmed that the corresponding power distribution device is in a mains power failure state.

[0009] In this embodiment of the application, after disconnecting all power distribution branches for a preset time, the communication status of other power distribution equipment in the power distribution system is obtained. If the power distribution equipment is in an online communication state, it is confirmed that the corresponding power distribution equipment is not in a mains power failure state. If the power distribution equipment is in an offline communication state, it is confirmed that the corresponding power distribution equipment is in a mains power failure state. In this way, by using the communication status of the power distribution equipment, it is possible to accurately identify whether the corresponding power distribution equipment is in a mains power failure state or not.

[0010] In some embodiments of this application, the method further includes: setting the preset time based on the power supply time that the auxiliary power supply can maintain when the mains power fails; the preset time is greater than the power supply time.

[0011] In this embodiment of the application, the preset time is set according to the power supply time that the auxiliary power supply can maintain when the mains power fails. In this way, after the preset time of disconnecting all power distribution branches of the power distribution equipment, the communication status of other power distribution equipment is obtained, so as to avoid the influence of misjudgment of communication status caused by the auxiliary power supply supplying power to other power distribution equipment.

[0012] In some embodiments of this application, the device status information includes a protection status; obtaining the device status information of other power distribution equipment in the power distribution system and confirming the mains connection status of the corresponding power distribution equipment based on the device status information includes: obtaining the protection status of other power distribution equipment in the power distribution system, the protection status including an undervoltage and underfrequency status; if the other power distribution equipment is in the undervoltage and underfrequency status, then confirming that the corresponding power distribution equipment is in a mains power failure state.

[0013] In this embodiment, if the other power distribution equipment is in an undervoltage and underfrequency state, it is confirmed that the corresponding power distribution equipment is in a mains power failure state. Thus, based on the undervoltage and underfrequency states of the other power distribution equipment, the corresponding power distribution equipment can be accurately confirmed to be in a mains power failure state. This avoids the waiting time required for auxiliary power supply to confirm that the corresponding power distribution equipment is in a mains power failure state, thereby reducing the waiting time needed to confirm this state. In some embodiments of this application, before disconnecting all power distribution branches in response to a received host verification command, the method further includes: obtaining and storing the device identification information of other power distribution equipment connected to the power distribution system.

[0014] In some embodiments of this application, after confirming that other power distribution equipment in the power distribution system is in a state of mains power failure, the current power distribution equipment is configured as a dispatching host to perform energy dispatching control on other power distribution equipment. The method includes: connecting all power distribution branches of the current power distribution equipment.

[0015] In this embodiment of the application, when it is confirmed that other power distribution equipment in the power distribution system is in a state of mains power failure, the current power distribution equipment is configured as a dispatch host to perform energy dispatch control on other power distribution equipment. Then, all power distribution branches of the current power distribution equipment are connected, which can facilitate the dispatch host to control other power distribution equipment.

[0016] In some embodiments of this application, the mains connection state further includes a mains power supply state, and the method further includes: when it is confirmed that at least one other power distribution device in the power distribution system is in a mains power supply state, configuring the current power distribution device as a scheduling slave and returning a verification failure instruction to the sender of the host verification instruction; the verification failure instruction is used to indicate that the current power distribution device is not a scheduling host; and / or after configuring the current power distribution device as a scheduling slave, controlling the current power distribution device in response to the scheduling instruction of the scheduling host.

[0017] In this embodiment, the current power distribution equipment is configured as a scheduling slave and a verification failure instruction is returned to the sender of the host verification instruction so that the sender can send verification instructions to other power distribution equipment in the power distribution system to verify whether other equipment is a scheduling slave.

[0018] In some embodiments of this application, disconnecting all power distribution branches in response to a received host verification command includes: disconnecting all power distribution branches in a preset order in response to a received host verification command; the method further includes: confirming the power distribution branch to which each power distribution device is connected based on the order of changes in the device status information of other power distribution devices in the power distribution system.

[0019] In this embodiment of the application, all power distribution branches are disconnected in a preset order; the method further includes: confirming the power distribution branch to which each power distribution device is connected based on the order of changes in the equipment status information of other power distribution devices in the power distribution system, so that the scheduling host can conveniently control other power distribution devices through the identified power distribution branches.

[0020] Secondly, embodiments of this application provide a power distribution device, including: a memory for storing program instructions; and a processor for reading and executing the program instructions stored in the memory, wherein when the program instructions are executed by the processor, the power distribution device performs the aforementioned host identification method.

[0021] Thirdly, embodiments of this application provide a computer storage medium storing program instructions. When the program instructions are run on an electronic device, the electronic device executes the aforementioned host identification method.

[0022] Furthermore, the technical effects brought about by the second and third aspects can be found in the descriptions of the methods in the above-mentioned method section, and will not be repeated here. Attached Figure Description

[0030] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0031] To better understand the above-mentioned objectives, features and advantages of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing an embodiment in one instance only and is not intended to be limiting of the application.

[0033] It should be noted that the terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and drawings of this application are used to distinguish similar objects, and not to describe a specific order or sequence. In the embodiments of this application, the words "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0034] With the increasing household electricity load, power distribution systems have gradually expanded from single distribution devices to interconnected systems, ensuring that each load has a corresponding distribution branch for connection and thus enabling power supply control for that load. Typically, multiple distribution devices in a power distribution system connect to the various distribution branches of a main distribution device, i.e., they are connected in a master-slave cascade manner. This main distribution device acts as a control unit, managing all the distribution devices in the system. However, identifying the main distribution device from among the master-slave cascaded devices remains a pressing technical problem.

[0035] To address the aforementioned technical problems, this application provides a host identification method. The method is applied to any power distribution equipment in a power distribution system. (Reference) Figure 1 The diagram shown is a structural schematic of a power distribution system provided in some embodiments of this application. The power distribution system 10 includes at least two power distribution devices 101, which are connected to each other via a preset communication method. For example, the at least two power distribution devices 101 can be connected via wired communication methods such as a Controller Area Network (CAN) bus or Ethernet, or via wireless communication methods such as Wi-Fi or Bluetooth. This application does not limit the communication method between the power distribution devices 10. The main power distribution device in the power distribution system 10 is connected to other power distribution devices in a master-slave cascade manner, thereby using the main power distribution device as a scheduling host to control each power distribution device in the power distribution system 10. Figure 1 For example, power distribution equipment A is the main power distribution equipment (i.e., the dispatching host), and power distribution equipment B and C are connected to two distribution branches of power distribution equipment A. After power distribution equipment A is connected to the mains power network 102, power distribution equipment A can control power distribution equipment B and C, and together with power distribution equipment B and C, perform energy dispatching on the mains power in the mains power network 102. It can be understood that when the power distribution equipment is connected to other input sources, it can perform energy dispatching based on the power supply priority between different input sources and the power consumption priority between different loads.

[0036] In some embodiments of this application, a relay (not shown in the figure) is provided on each power distribution branch. By controlling the closing or opening of the relay, the corresponding power distribution branch can be turned on or off.

[0037] The following combination Figure 1 This application describes a host identification method provided in its embodiments. (See references...) Figure 2 The diagram shown is a flowchart of a host identification method provided in some embodiments of this application. Figure 2 The example method includes one or more steps, but does not constitute a limitation of this application. Furthermore, the order of the steps is merely illustrative and may be changed. Additional steps may be added or steps may be removed without departing from the disclosure of this application. The host identification method includes the following steps.

[0038] Step S201: In response to the received host verification command, disconnect all power distribution branches.

[0039] In some embodiments of this application, a user can send a host verification command to any power distribution device 101 in the power distribution system 10 via a terminal device to verify whether the current power distribution device is the dispatch host. The current power distribution device refers to the power distribution device that receives the host verification command.

[0040] In some embodiments of this application, the terminal device may be communicatively connected to some or all of the power distribution equipment 101 in the power distribution system 10.

[0041] The terminal device displays an application interface where the user can select a power distribution device for verification by the dispatch host. In response to the user's selection, the terminal device generates a host verification command and sends it to the selected power distribution device. Upon receiving the host verification command, the selected power distribution device disconnects all its power distribution branches.

[0042] For example, refer to Figure 1 As shown, after receiving the host verification command, power distribution equipment A disconnects the power distribution branches connected to power distribution equipments B and C. In some embodiments of this application, after receiving the host verification command, power distribution equipment A can disconnect the power distribution branch connected to power distribution equipment B by turning off the relay on the power distribution branch connected to power distribution equipment B. Similarly, the power distribution branch connected to power distribution equipment C can be disconnected by turning off the relay on the power distribution branch connected to power distribution equipment C.

[0043] In some embodiments of this application, before disconnecting all power distribution branches in response to the received host verification command, S201 further includes: obtaining and storing the device identification information of other power distribution equipment connected to the power distribution system.

[0044] refer to Figure 1 As shown, after receiving the host verification command, power distribution equipment A obtains and stores the device identification information of all power distribution equipment (such as power distribution equipment B and C) that are communicatively connected to power distribution equipment A in the power distribution system. In some embodiments of this application, power distribution equipment A can also generate and store a device list based on the device identification information of the power distribution equipment.

[0045] In some embodiments of this application, disconnecting all power distribution branches in response to a received host verification command includes: identifying all power distribution branches connected to the current power distribution device based on stored device identification information of all power distribution devices communicatively connected to the current power distribution device, and then disconnecting all power distribution branches of the current power distribution device. For example, after receiving a host verification command, power distribution device A identifies power distribution branches P1 and P2 connected to it based on stored device identification information of power distribution devices B and C communicatively connected to power distribution device A, and then disconnects all power distribution branches of power distribution device A.

[0046] Step S202: Obtain the equipment status information of other power distribution equipment in the power distribution system, and confirm the mains power connection status of the corresponding power distribution equipment based on the equipment status information.

[0047] In some embodiments of this application, the mains connection state includes a mains power failure state and a mains power supply state. A mains power supply state indicates that the corresponding power distribution equipment is connected to the mains power, while a mains power failure state indicates that the corresponding power distribution equipment is not connected to the mains power.

[0048] Step S203: When it is confirmed that other power distribution equipment in the power distribution system is in the state of mains power failure, the current power distribution equipment is configured as the dispatch host to perform energy dispatch control on other power distribution equipment.

[0049] In one embodiment, the power distribution equipment may also be equipped with a dispatch host identifier. When the power distribution equipment is confirmed to be a dispatch host, the dispatch host identifier is configured as true; otherwise, it is configured as false. Therefore, in subsequent control processes, the user can identify whether it is a dispatch host by recognizing this dispatch host identifier.

[0050] In another embodiment, when the number or connection relationship of power distribution equipment in the power distribution system changes, a new host verification instruction is triggered. At this time, the scheduling host identifier is cleared so that it can be assigned a value according to the new verification result.

[0051] In some embodiments of this application, the device status information includes communication status, and the current power distribution equipment can determine the mains connection status of the corresponding power distribution equipment based on the communication status of other power distribution equipment in the power distribution system. Figure 3The diagram shows a flowchart of a method for confirming the mains connection status of corresponding power distribution equipment according to some embodiments of this application. The method includes the following steps.

[0052] Step S301: After disconnecting all power distribution branches for a preset time, obtain the communication status of other power distribution equipment in the power distribution system. The communication status includes online communication status and offline communication status.

[0053] In some embodiments of this application, "communication online status" indicates that the current power distribution equipment can communicate with other power distribution equipment through a preset communication method. "Communication offline status" indicates that the current power distribution equipment cannot communicate with other power distribution equipment through a preset communication method.

[0054] Step S302: If the power distribution equipment is in an online communication state, then confirm that the corresponding power distribution equipment is not in a state of mains power failure.

[0055] In some embodiments of this application, if the power distribution equipment is in an online communication state, it is confirmed that the corresponding power distribution equipment is in a mains power supply state and can be powered by mains power.

[0056] Step S303: If the power distribution equipment is in a communication offline state, then confirm that the corresponding power distribution equipment is in a mains power failure state.

[0057] In some embodiments of this application, if the power distribution equipment is in a communication offline state, it is confirmed that the corresponding power distribution equipment is in a mains power failure state and the corresponding power distribution equipment cannot be powered by mains power.

[0058] refer to Figure 1 As shown, if power distribution equipment A is the dispatching host, it means that the mains power can supply power to power distribution equipment A and other power distribution equipment connected to power distribution equipment A (such as power distribution equipment B and C). Before all power distribution branches of power distribution equipment A are disconnected, the mains power can supply power to power distribution equipment B and C, making power distribution equipment B and C in an online communication state. After a preset time of disconnecting all power distribution branches of power distribution equipment A, power distribution equipment B and C are in a closed state due to lack of mains power supply, resulting in power distribution equipment B and C being in an offline communication state. In this embodiment, if power distribution equipment B or C is in an online communication state, it is confirmed that the corresponding power distribution equipment is not in a mains power failure state; if power distribution equipment B or C is in a offline communication state, it is confirmed that the corresponding power distribution equipment is in a mains power failure state.

[0059] In some embodiments of this application, when all power distribution devices B and C in the power distribution system other than power distribution device A are in a state of mains power failure, it means that power distribution devices B and C are connected to power distribution device A, and power distribution devices B and C need to obtain mains power supply through the power distribution branch of power distribution device A. In this way, power distribution device A can be configured as a dispatch host to perform energy dispatch control on power distribution devices B and C.

[0060] In some embodiments of this application, when at least one of the power distribution equipment B and C is not in a state of mains power failure, it means that at least one of the power distribution equipment B and C is not connected to the power distribution branch of power distribution equipment A, and at least one of the power distribution equipment B and C does not need to obtain mains power supply through the power distribution branch of power distribution equipment A. In this way, power distribution equipment A can be configured as a scheduling slave.

[0061] In some embodiments of this application, considering that the power distribution equipment can be temporarily powered by an auxiliary power source in the event of a mains power outage, in order to accurately confirm whether the power distribution equipment is in a communication offline state due to the mains power outage, the communication status of power distribution equipment B and C can be obtained after a preset time has been elapsed since all power distribution branches of power distribution equipment A were disconnected. This avoids misjudgment of the communication status caused by the auxiliary power source supplying power to power distribution equipment B and C. In some embodiments of this application, the preset time can be set according to the power supply time that the auxiliary power source can maintain in the event of a mains power outage, wherein the preset time is longer than the power supply time that the auxiliary power source can maintain.

[0062] In other embodiments of this application, the device status information includes protection status, and the current power distribution equipment can determine the mains connection status of the corresponding power distribution equipment based on the protection status of other power distribution equipment in the power distribution system. (See reference) Figure 4 The diagram shown is a flowchart of a method for confirming the mains connection status of corresponding power distribution equipment according to some embodiments of this application. The method includes the following steps.

[0063] Step S401: Obtain the protection status of other power distribution equipment in the power distribution system.

[0064] The protection status includes undervoltage and underfrequency status as well as normal status.

[0065] Step S402: If the other power distribution equipment is in an undervoltage and underfrequency state, then it is confirmed that the corresponding power distribution equipment is in a mains power failure state.

[0066] Undervoltage and underfrequency conditions indicate that the voltage of the power distribution equipment is below the standard voltage range of the power grid, and the frequency of the power distribution equipment is below the standard frequency range of the power grid. Normal conditions indicate that the voltage of the power distribution equipment is within the standard voltage range of the power grid, and the frequency of the power distribution equipment is within the standard frequency range of the power grid.

[0067] In some embodiments of this application, after other power distribution equipment in the power distribution system loses power, the protection state of the mains interface of the other power distribution equipment is undervoltage and underfrequency. Since the auxiliary power supply of the other power distribution equipment can still provide power after a power outage, the other power distribution equipment can still obtain the protection state of its mains interface in the event of a power outage. This application can confirm that the corresponding power distribution equipment is in a mains power failure state by detecting that other power distribution equipment is in an undervoltage and underfrequency state.

[0068] For example, refer to Figure 1 After a power outage, auxiliary power supplies in power distribution equipment B and C can supply power to them, thus allowing them to obtain their own protection status. If power distribution equipment B and C are confirmed to be in an undervoltage / underfrequency state, then they are confirmed to be in a mains power outage state. When it is confirmed that both power distribution equipment B and C are in the mains power outage state, power distribution equipment A is configured as a dispatching host to perform energy dispatching control on power distribution equipment B and C.

[0069] In some embodiments of this application, disconnecting all power distribution branches in response to a received host verification command includes: disconnecting all power distribution branches in a preset order in response to the received host verification command. The method further includes: confirming the power distribution branch to which each power distribution device is connected based on the order in which the device status information of other power distribution devices in the power distribution system changes. In some embodiments of this application, confirming the power distribution branch to which each power distribution device is connected is based on the order in which the protection status of other power distribution devices in the power distribution system changes from a normal state to an undervoltage / underfrequency state.

[0070] For example, after receiving the host verification command, power distribution equipment A, following a preset sequence, first disconnects the power distribution branch P1 to which it is connected in the power distribution system while maintaining the connection of power distribution branch P2. If the protection status of power distribution equipment B changes from normal to undervoltage / underfrequency, then it is confirmed that power distribution equipment B is connected to power distribution branch P1. Then, after disconnecting power distribution branch P1 to which power distribution equipment A is connected in the power distribution system, it disconnects power distribution branch P2. If the protection status of power distribution equipment C changes from normal to undervoltage / underfrequency, then it is confirmed that power distribution equipment C is connected to power distribution branch P2.

[0071] In some embodiments of this application, when configuring the current power distribution equipment as the dispatch host, the method further includes: returning a verification success instruction to the sender of the host verification instruction; and / or outputting a verification success instruction to other power distribution equipment in the power distribution system; the verification success instruction is used to indicate that the current power distribution equipment is the dispatch host; the verification success instruction carries the equipment identification information of the current power distribution equipment.

[0072] For example, refer to Figure 1 As shown, if power distribution device A is configured as the dispatch host, power distribution device A sends a successful verification command to the terminal device. The successful verification command carries the device identification information of power distribution device A. Thus, the device identification information of the dispatch host can be notified to the terminal device through the successful verification command, thereby enabling the terminal device to configure power distribution device A as the dispatch host. Simultaneously, after receiving the successful verification command, the terminal device will not send host verification commands to other power distribution devices.

[0073] In one embodiment, power distribution device A can also output a verification success command to power distribution devices B and C (i.e., dispatch slaves). The verification success command carries the device identification information of power distribution device A. In this way, the device identification information of the dispatch master can be notified to the dispatch slaves through the verification success command, so that other power distribution devices can configure themselves as dispatch slaves and obtain the information of the dispatch master, so as to respond to the control signals from the dispatch master in subsequent processes.

[0074] In some embodiments of this application, the mains connection state further includes a mains power supply state, and the method further includes: when it is confirmed that at least one other power distribution device in the power distribution system is in a mains power supply state, configuring the current power distribution device as a scheduling slave and returning a verification failure instruction to the sender of the host verification instruction; the verification failure instruction is used to indicate that the current power distribution device is not a scheduling host; and / or after configuring the current power distribution device as a scheduling slave, controlling the current power distribution device in response to the scheduling instruction of the scheduling host.

[0075] For example, after disconnecting all power distribution branches connected to power distribution equipment A, and confirming that at least one of power distribution equipment B or C in the power distribution system is under mains power supply, power distribution equipment A is configured as a dispatch slave, and a verification failure command is returned to the terminal device. This verification failure command indicates that power distribution equipment A is not the dispatch master. After configuring power distribution equipment A as a dispatch slave, power distribution equipment A can also be controlled in response to dispatch commands from the dispatch master.

[0076] In one embodiment, after the full scheduling host confirms the connection, all power distribution branches of the current power distribution equipment are also activated to restore power supply to the load after the host identification is completed.

[0077] refer to Figure 5 The diagram shown is a structural schematic of a host identification device provided in some embodiments of this application. The host identification device 50 can be used to implement... Figure 2 and Figure 3 The host identification method shown.

[0078] Specifically, the host identification device 50 includes a switch module 501, a confirmation module 502, and a configuration module 503.

[0079] Switch module 501 is used to disconnect all power distribution branches in response to a received host verification command.

[0080] The confirmation module 502 is used to obtain the equipment status information of other power distribution equipment in the power distribution system, and to confirm the mains power connection status of the corresponding power distribution equipment based on the equipment status information.

[0081] The configuration module 503 is used to configure the current power distribution device as a dispatching host to perform energy dispatching control on the other power distribution devices when it is confirmed that other power distribution devices in the power distribution system are in the state of mains power failure.

[0082] In some embodiments of this application, after disconnecting all power distribution branches for a preset time, the confirmation module 502 obtains the communication status of other power distribution equipment in the power distribution system; if the power distribution equipment is in an online communication state, it is confirmed that the corresponding power distribution equipment is not in a mains power failure state; if the power distribution equipment is in an offline communication state, it is confirmed that the corresponding power distribution equipment is in a mains power failure state.

[0083] In some embodiments of this application, the confirmation module 502 obtains the protection status of other power distribution equipment in the power distribution system; if the other power distribution equipment is in an undervoltage and underfrequency state, the corresponding power distribution equipment is confirmed to be in a mains power failure state.

[0084] It is understood that the host identification device 50 and the above-mentioned Figure 2 The host identification method shown belongs to the same inventive concept. The specific process of the host identification device 50 implementing the host identification method is the same as that of the above embodiments, and will not be repeated here.

[0085] This application also provides a computer-readable storage medium. The computer-readable storage medium stores multiple instructions adapted to be loaded and executed by a processor to implement corresponding steps of the host identification method described above, such as steps S201-S203, S301-303, and S401-402.

[0086] Please refer to Figure 6 The diagram shown is a structural schematic of a power distribution device 60 provided in some embodiments of this application. The power distribution device 60 may include at least one memory 601, a processor 602, and a communication unit 603. The memory 601 includes a computer-readable storage medium for storing multiple logical instructions. The communication unit 603 is used to communicate with terminal devices or other power distribution devices. The processor 602 can execute the logical instructions to perform the aforementioned host identification method. Specifically, the power distribution device 60 may be a power distribution cabinet or a power distribution box; this application does not limit its application to this.

[0087] It is understood that in some embodiments, the communication unit 603 includes modules with communication functions such as network modules, and this application does not limit this.

[0088] The logical instructions in the aforementioned computer-readable storage medium can be implemented in the form of software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.
