[0056] In order to make the technical solution in the embodiments of the present application clearer, the drawings needed in the embodiment description will be briefly introduced as follows. Obviously, the drawings in the following description are only some embodiments of the present application, and all other drawings obtained by those skilled in the art without any creative effort should be within the protection scope of the present application.

[0057] It should be noted that the terms "first", "second" and the like in the description and in the claims of the present application and above-described accompanying drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in other than the order illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a list of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to such processes, methods, products or devices.

[0058] Figure 1a A flowchart of a main control identification allocation method provided by an embodiment of the present application, which can be applicable to the automatic allocation of identification information to multiple main controls in an energy storage system, can be executed by an identification allocation device of the main control in the energy storage system, which can be realized in the form of hardware and / or software and configured in the general control of the energy storage system. As shown in Figure 1a The method comprises the following steps:

[0059] In step 110, a first broadcast data packet is sent to each main control deployed in the energy storage system in response to the identification allocation request.

[0060] In this embodiment, Figure 1b A connection diagram of a general control and a main control in an energy storage system according to an embodiment of the present application is shown in Figure 1b As shown in the figure, a general control (BAU) and a main control link are deployed in the energy storage system, multiple main controls (BCU1, BCU2, BCU3, BCU4, etc.) in the main control link are connected in series, and the general control is connected to the first main control in the main control link.

[0061] In a specific embodiment, if the personnel of the energy storage system need to use the general control and the main control for data interaction, an identification allocation request can be triggered for the general control, or when other network devices in the energy storage system need to control the general control and the main control for data interaction, an identification allocation request can also be triggered for the general control, which is not limited in this embodiment.

[0062] In this step, after receiving the identification allocation request, the general control can send a first broadcast data packet to each main control to initiate a call to all main controls. Specifically, the first broadcast data packet corresponds to a broadcast address 255.255.255.255, which is used to indicate that the general control sends a data packet to all main controls in the same local area network, and the protocol type that the data packet satisfies can be a user datagram protocol (User Datagram Protocol, UDP).

[0063] Step 120, after receiving the response message of each master feedback to the first broadcast data packet, a second broadcast data packet is sent to each master.

[0064] In this embodiment, each master can feed back a response message to the master controller after receiving the first broadcast data packet. Optionally, the response message can be used to inform the master controller that the corresponding master is running normally, such as a normal transmission link or a normal function parameter configuration.

[0065] In this step, after receiving the response message feedback from each master, the master controller can repeat the operation of step 110, that is, a second broadcast data packet is sent to each master.

[0066] Step 130, according to the response result of each master to the second broadcast data packet, when it is determined that each master meets the allocation condition, the corresponding identification information is allocated to each master.

[0067] In this embodiment, each master can decide whether to make a response result after receiving the second broadcast data packet. Optionally, the response result can be used to inform the master controller whether the corresponding master is ready for identification information allocation.

[0068] In this step, the master controller can allocate the corresponding identification information to the master when it is determined that the master meets the allocation condition according to the response result of the master to the second broadcast data packet. Specifically, each master can enter a locked state after the identification information allocation is completed, so that the master controller allocates identification information to the next master. The identification information can include an identification (ID).

[0069] The technical scheme provided by the embodiment of the application, by the master controller in the energy storage system responding to the identification allocation request, sending a first broadcast data packet to each master deployed in the energy storage system, receiving the response message of each master feedback to the first broadcast data packet, sending a second broadcast data packet to each master, according to the response result of each master to the second broadcast data packet, determining that each master meets the allocation condition, and allocating the corresponding identification information to each master, provides a master controller and master using an Ethernet hand-in-hand connection mode, and the master controller uses a broadcast mode to realize identification allocation to each master, without the support of hardware signals. Compared with the manual allocation of identification by related personnel in the prior art, the human and time resources consumed in the master identification allocation process can be saved, and the efficiency of master identification allocation and the operation efficiency of the energy storage system are improved.

[0070] Figure 2Another flowchart of the method for assigning the identifier of the master control in the energy storage system is provided in the embodiments of the present application, which is applied to the master control of the energy storage system, as shown in the figure, and the method comprises the steps of: Figure 2

[0071] In step 210, the first broadcast data packet is sent to each master control deployed in the energy storage system in response to the identifier assignment request.

[0072] In the embodiments, as shown in the figure, the switch in the switch chip built in each master control further comprises a data switch, and the first broadcast data packet is used to instruct each master control to disconnect the data switch of the built-in switch chip. Figure 1b

[0073] In this step, specifically, after each master control in the energy storage system receives the first broadcast data packet, a response message can be fed back to the master control, and then the data switch of the respective switch chip is disconnected, so that the master control can subsequently assign the identifier to each master control one by one.

[0074] In step 220, the second broadcast data packet is sent to each master control after receiving the response message fed back by each master control in response to the first broadcast data packet.

[0075] In the embodiments, optionally, after receiving the response message fed back by each master control in response to the first broadcast data packet, the method further comprises the step of: counting the total number of master controls currently deployed in the energy storage system according to the response message fed back by each master control in response to the first broadcast data packet.

[0076] Specifically, the master control can count the total number of master controls currently deployed in the energy storage system according to the media access control (MAC) address in the response message fed back by the master control.

[0077] In step 230, if each master control does not respond to the second broadcast data packet, it is determined that each master control meets the assignment condition.

[0078] In the embodiments, after the master control sends the second broadcast data packet to each master control, it can wait for a preset time period, and if each master control does not respond after the waiting period ends, it can be determined that each master control meets the identifier information assignment condition. The preset time period can be 1s, and the specific value can be adjusted according to the actual situation, and the embodiments do not limit this.

[0079] In step 240, one master control is determined as the current processing master control in the master control link.

[0080] ​​Step 250, assigning corresponding identification information to the current processing master, and sending a data switch closing instruction to the current processing master to make the current processing master close the built-in switch chip data switch.

[0081] In this embodiment, after assigning corresponding identification information to the current processing master, the method further comprises: updating the number of the currently recorded assigned masters. Specifically, the total control can increase the recorded number of the assigned masters by one after completing the assignment operation of one master.

[0082] In one embodiment of this embodiment, sending the data switch closing instruction to the current processing master comprises: judging whether the assignment completion response data fed back by the current processing master is received; if yes, sending the data switch closing instruction to the current processing master.

[0083] In this embodiment, after the current processing master receives the identification information, the corresponding working state can be marked as an assigned state, and then the assignment completion response data is fed back to the total control. After the total control receives the assignment completion response data, the data switch closing instruction can be sent to the current processing master. Under this closing instruction, the current processing master can close the built-in switch chip data switch, so that the total control can start the assignment operation of the next master again.

[0084] In one specific embodiment, if the total control does not receive the assignment completion response data fed back by the current processing master, the identification information can be assigned to the current processing master again, or an abnormal alarm can be triggered, etc.

[0085] Step 260, judging whether the assignment operation of all the masters is completed, if yes, determining that the identification assignment method is executed to be ended, if not, returning to execute the operation of determining one master in the master link as the current processing master in step 240, until the assignment operation of all the masters is completed.

[0086] In this step, judging whether the assignment operation of all the masters is completed comprises: judging whether the assignment operation of all the masters is completed according to the number of the currently assigned masters and the total number of the masters.

[0087] Specifically, the number of the currently assigned masters can be compared with the total number of the masters, and whether the assignment operation of all the masters is completed can be judged according to the comparison result.

[0088] The technical scheme provided by the embodiment of the application comprises the following steps: in response to an identification allocation request, a total controller in an energy storage system sends a first broadcast data packet to each master controller deployed in the energy storage system; after receiving a response message fed back by each master controller in response to the first broadcast data packet, the total controller sends a second broadcast data packet to each master controller; if each master controller does not respond to the second broadcast data packet, it is determined that each master controller meets the allocation condition; one master controller in the master controller link is determined as a current processing master controller in sequence; the corresponding identification information is allocated to the current processing master controller; a data switch closing instruction is sent to the current processing master controller, so that the current processing master controller closes the built-in switch chip data switch; it is determined whether the allocation operation on all master controllers is completed; if not, the operation of determining one master controller in the master controller link as a current processing master controller in sequence is returned to be executed until the allocation operation on all master controllers is completed. The technical scheme can save human resources and time resources consumed in the master controller identification allocation process, and improves the allocation efficiency of the master controller identification and the operation efficiency of the energy storage system.
