In order to manage the whole life cycle of the battery (for example, battery production, storage, transportation, recycling, etc.), a battery management system (battery management system, BMS) is usually set up. The BMS mainly includes a battery control unit (which can be referred to as the main control board) and battery management unit (may be referred to as slave board for short). Wherein, a management node (also referred to as a sending node hereinafter) is deployed on the main control board, and a terminal node (also referred to as a receiving node hereinafter) is deployed on the slave board, and communication and interaction can be performed between the management node and the terminal node. For example, after the deployment acquires the corresponding cell information from the sensor on the board, the terminal node may send the cell information to the management node.

The premise of the communication interaction between the management node and the terminal node is to establish a communication connection. In order to establish a communication connection between the terminal node and the management node, the management node needs to periodically send a broadcast message, so that the terminal node establishes a communication connection with the terminal node based on the broadcast message. In this way, the management node will consume a large amount of energy. Therefore, how to reduce the energy consumption of the management node is an urgent problem to be solved.

Some concepts involved in the embodiments of the present application are introduced above, and the technical features of the embodiments of the present application are introduced below. In the following, the method and the device are based on the same technical concept. Since the principles of the method and the device to solve the problem are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

The system architecture applicable to the embodiment of the present application is introduced below.

Architecture one

Please refer to FIG. 1. FIG. 1 shows a schematic diagram of a possible communication system applicable to the embodiment of the present application. The system includes a sending node, a node 1, a node 2, a node 3, a node 4, a node 5, and a node 6 .

Among them, node 1, node 2, node 3, node 4, node 5 and node 6 are receiving nodes. Therefore, the sending node may send first information, where the first information includes connection configuration information, and the connection configuration information may be used by the receiving node to establish a communication connection with the sending node. Correspondingly, node 1, node 2, node 3, node 4, node 5, and node 6 may receive the first information, and establish a communication connection with the sending node based on the connection configuration information in the first information.

It can be understood that the number of target receiving nodes that can establish communication with the sending node is limited. Therefore, when the sending node determines that the number of target receiving nodes with which communication connections have been successfully established reaches the first threshold, the sending node performs the first operation. Wherein, the first operation may be to stop sending the first information, or may be to send updated first information, and the updated first information does not include connection configuration information, or may be to send second information, and the second information includes connection configuration information. The configuration information and the indication mark may indicate that the receiving node is prohibited from creating a new communication connection with the sending node and/or the receiving node is prohibited from scanning the sending node. Exemplarily, the first threshold is 3 as an example. If

nodes

1, 2, and 3 have successfully established connections with the sending node, the number of target receiving nodes that have successfully established communication connections with the sending node has reached the first threshold, and the sending node The node stops sending the first information or sending the updated first information or sending the second information. In a possible implementation, node 4, node 5, and node 6 have not successfully established a connection with the sending node because they did not receive the first information correctly, so by stopping sending the first information or sending the updated first Information or sending second information can prevent or prohibit node 4, node 5 and node 6 from residing in the management range or coverage of the sending node or establishing a communication connection with the sending node, thereby reducing the energy consumption of the sending node. In another possible implementation, if the current node 4, node 5, and node 6 have received the first information, but fail to establish a connection with the sending node, by sending the second information, nodes 4, 6, and Nodes 5 and 6 reside in the management range or coverage range of the sending node and/or establish a communication connection with the sending node, effectively reducing the energy consumption of the sending node.

It can be understood that the receiving nodes in the communication system shown in FIG. 1 above are taken as examples of

nodes

1, 2, 3, 4, 5, and 6, and are not limited thereto. In other possible embodiments, There can be more or fewer receiving nodes in the communication system.

Architecture two

Different from the first architecture, in the second architecture, the sending node can manage the receiving nodes in groups, and communicate and interact with the receiving nodes in the group within the time window corresponding to each group. In this way, the communication resources of the sending node are allocated reasonably, and the receiving nodes in each group are managed, so that the granularity of the sending node management is finer, and the energy consumption of the sending node can be reduced at the same time.

Please refer to FIG. 2 again. FIG. 2 shows a schematic structural diagram of another communication system to which this embodiment of the present application is applicable. In FIG. 2 , the system includes a sending node, node 1 , node 2 , node 3 , node 4 , node 5 and node 6 .

Among them, node 1, node 2, node 3, node 4, node 5 and node 6 are all receiving nodes, which can communicate and interact with the sending node. The sending node can communicate and interact with the receiving nodes in the group within the time window corresponding to each group, and limit the number of nodes allowed to establish communication connections with the sending node in each group. In FIG. 2, node 1, node 2, and node 3 belong to the first group, and the first group corresponds to the first time window; node 4, node 5, and node 6 belong to the second group, and the second group corresponds to the second time window. The first threshold corresponding to the first group (that is, the number of nodes that are allowed to establish a communication connection with the sending node in the first group) is 2 as an example, and the second threshold corresponding to the second group (that is, the number of nodes that are allowed to establish communication with the sending node in the second group) The number of connected nodes) take 1 as an example.

The sending node may send first information within the first time window, where the first information includes first connection configuration information, and the first connection configuration information may be used by the receiving node to establish a communication connection with the sending node. Correspondingly, node 1, node 2, and node 3 may receive the first information, and establish a communication connection with the sending node based on the first connection configuration information in the first information. If

nodes

1 and 2 have successfully established communication connections with the sending node within the first time window, the number of nodes in the first group that have successfully established communication connections with the sending node reaches the first threshold, and the sending node can stop sending messages containing the first The first information of the connection configuration information; or sending the updated first information; or sending the second information (including the first connection configuration information and the first indicator), the first indicator may indicate that the receiving node and the sending node are prohibited from creating new The communication connects and/or prohibits the receiving node from scanning the sending node. In a possible implementation, node 3 has not successfully established a connection with the sending node because it has not received the first information correctly, so by stopping sending the first information or sending the updated first information or sending the second information , the node 3 can be prevented or prohibited from camping in the management range or coverage of the sending node or establishing a communication connection with the sending node, thereby reducing the energy consumption of the sending node. In another possible implementation, if node 3 has received the first information, but fails to establish a connection with the sending node, by sending the second information, it can prevent or prohibit node 3 from being in the management range or coverage of the sending node. The range resides or establishes a new communication connection with the sending node, thereby reducing the energy consumption of the sending node.

Similarly, the sending node may send third information within the first time window, where the third information includes second connection configuration information, and the second connection configuration information may be used by the receiving node to establish a communication connection with the sending node. Correspondingly, node 4, node 5, and node 6 may receive the third information, and establish a communication connection with the sending node based on the second connection configuration information in the third information. If node 4 has successfully established a communication connection with the sending node within the second time window, the number of nodes in the second group that have successfully established a communication connection with the sending node reaches the second threshold, and the sending node can stop sending information containing the second connection configuration information. or send updated third information (excluding the second connection configuration information), or send fourth information (including the second connection configuration information and the second indication). The second indication may indicate that the receiving node is prohibited from creating a new communication connection with the sending node and/or the receiving node is prohibited from scanning the sending node. In a possible implementation manner, because nodes 5 and 6 did not receive the third information correctly, they did not successfully establish a connection with the sending node, so by stopping sending the third information or sending updated third information or sending The fourth information can prevent or prohibit nodes 5 and 6 from camping in the management area or coverage area of the sending node or establishing a communication connection with the sending node, thereby reducing the energy consumption of the sending node. In another possible implementation, if node 5 and node 6 have received the first message, but fail to establish a connection with the sending node, by sending the fourth message, nodes 5 and 6 can be prevented or prohibited from being connected to the sending node. The management area or coverage area resides or establishes a communication connection with the sending node, thereby reducing the energy consumption of the sending node.

The technical features of the embodiments of the present application are described below in conjunction with specific drawings.

Embodiment one

Please refer to FIG. 9 , which shows a schematic flowchart of the first communication method provided by the embodiment of the present application. In the following introduction process, it is taken as an example that this method is applied to the system architecture shown in FIG. 1 or FIG. 4 . The method includes:

S901. The sending node sends first information. Correspondingly, the receiving node receives the first information.

Wherein, the first information includes connection configuration information, and the connection configuration information is used for establishing a communication connection between the receiving node and the sending node. Correspondingly, after receiving the first information, the receiving node may establish a communication connection with the sending node based on the connection configuration information in the first information.

In this embodiment of the present application, the connection configuration information includes at least one of a communication domain domain name, a communication domain identifier, a layer 2 link identifier, or a physical layer identifier of the sending node. It can be understood that, in this embodiment of the application, "communication domain" refers to a management area or coverage area centered on the sending node. In this management area or coverage area, the receiving node can establish a communication connection with the sending node, and carry out information exchange. Correspondingly, "communication domain domain name" refers to the name of the node that provides communication services in the management area or coverage area, for example, it can be at least one of the node name of the sending node, the name of the AP, the name of the base station, or the name of the server ;"Communication Domain Identity" refers to the identity of the node that provides communication services in this management area or coverage area, for example, it can be at least one of the node identity of the sending node, the identity of the AP, the identity of the base station, or the identity of the server;" Layer 2 link identifier" refers to the identifier formed by Ethernet to uniquely identify the sending node on the layer 2 link, for example, it can be an identifier formed by 16 bits or 48 bits; "physical layer identifier" refers to the physical layer corresponding to the sending node logo.

In a possible implementation manner, the first information is a broadcast message, and the sending node may send the first information in a broadcast form. In another possible implementation manner, the first information may also be a multicast message, and the sending node may send the first information in a multicast form.

S902. The sending node determines that the number of target receiving nodes that have successfully established communication connections with the sending node currently reaches a first threshold, and performs a first operation.

In this embodiment of the application, there are multiple ways to implement the first operation, including but not limited to any of the following ways:

Mode 1, stop sending the first information including the connection configuration information.

Exemplarily, please continue to refer to FIG. 1 , the receiving nodes are Node 1 , Node 2 , Node 3 , Node 4 , Node 5 , and Node 6 as examples, and the first threshold is 3 as an example. If the sending node detects that node 2, node 3, and node 4 have successfully established communication connections with them, it determines that the number of target receiving nodes that have successfully established communication connections with the sending node has reached the first threshold, and the sending node stops sending the first message. In this way, stopping sending the first information can effectively reduce the energy consumption of the sending node. In a possible implementation, other nodes that have not successfully established a communication connection with the sending node, such as node 1, node 5, and node 6, may not have received the first information correctly, so it can be realized by stopping sending the first information to prevent Or the above-mentioned nodes are prohibited from staying in the management area or coverage area of the sending node or establishing a communication connection with the sending node, so as to further reduce the energy consumption of the sending node.

Mode 2: Send updated first information, where the updated first information does not include connection configuration information.

It can be understood that, in one design, the updated first information is mainly reflected in that the connection configuration information is removed relative to the above-mentioned first information including the connection configuration information. Further, there may be other time- or flow-related differences between the updated first information and the above-mentioned first information including connection configuration information, which are not specifically limited in this application.

Exemplarily, please continue to refer to FIG. 1 , the receiving nodes take node 1, node 2, node 3, node 4, node 5 and node 6 as examples, and the first threshold takes 3 as an example. If the sending node detects that node 4, node 5, and node 6 have successfully established a communication connection with the sending node, it is determined that the number of target receiving nodes that have successfully established a communication connection with the sending node has reached the first threshold, and the sending node sends an updated The updated first information does not include connection configuration information. In this way, sending the updated first information (that is, the first information not including the connection configuration information) reduces the amount of information to be sent by the sending node, and can effectively reduce the energy consumption of the sending node. In a possible implementation, other nodes that have not successfully established a communication connection with the sending node, such as node 1, node 2, and node 3, may not have received the first information correctly, so it can be implemented by sending the updated first information However, the aforementioned nodes are prevented or prohibited from staying in the management range or coverage of the sending node or establishing a communication connection with the sending node, thereby effectively reducing the energy consumption of the sending node.

It should be noted that the updated first information may be received by Node 4, Node 5 and/or Node 6 that have successfully established a communication connection with the sending node, and at this time Node 4-Node 6 continue to maintain the original communication connection , not affected by the updated first information.

Mode 3: Sending second information, the second information includes connection configuration information and an indicator, and the indicator is used to indicate that the receiving node is prohibited from creating a new communication connection with the sending node and/or the receiving node is prohibited from scanning the sending node.

It can be understood that in the embodiment of the present application, "prohibiting the receiving node from establishing a new communication connection with the sending node" can be understood as prohibiting the receiving node from sending a connection establishment request to the sending node, or it can be understood that the sending node cannot provide more information for the receiving node. Multiple wireless access point (access point, AP) information or base station information to achieve load balancing or access control status. And, in this embodiment of the application, "prohibit the receiving node from scanning the sending node" can be understood as all the information or available services of the sending node have been sent, and the receiving node is prohibited from sending a scanning request to the sending node, and the scanning request can be used Or, it can be understood that the sending node cannot provide more wireless AP information or base station information to the receiving node to achieve load balancing or access control status. The receiving node here refers to a node that receives the second information.

It should be noted that the above-mentioned first information and second information both carry information (such as connection configuration information) required for establishing a communication connection between the receiving node and the sending node, but some information elements contained in the first information and the second information ( For example, the indication marks) are different, or the second information carries more information than the first information, and the present application does not limit specific differences. For example, when both the first information and the second information are broadcast messages, both the first information and the second message include an indicator, but the indicator in the first information is used to indicate that the receiving node is allowed to establish a new communication connection with the sending node and/or Or the receiving node is allowed to scan the sending node, and the indication in the second information is used to indicate that the receiving node is prohibited from creating a new communication connection with the sending node and/or the receiving node is prohibited from scanning the sending node.

Correspondingly, in this embodiment of the application, "allowing the receiving node to create a new communication connection with the sending node" can be understood as allowing the receiving node to send a connection establishment request to the sending node, or it can be understood that the sending node can also provide more information for the receiving node. Status of multi-AP information or base station information. And, "allowing the receiving node to scan the sending node" can be understood as the sending node's information or available services have not been sent, allowing the receiving node to send a scanning request to the sending node, and the scanning request can be used to request other information or services; or , it can be understood that the sending node is in a state where it can provide more wireless AP information or base station information for the receiving node. The receiving node here may refer to a node that receives the first information.

Exemplary, please continue to refer to Figure 1, the receiving node is taken as an example of node 1, node 2, node 3, node 4, node 5 and node 6, and the first threshold is 3 as an example, if the sending node detects that node 4, node 5. And node 6 has successfully established a communication connection with the sending node, then it is determined that the number of target receiving nodes that have successfully established a communication connection with the sending node has reached the first threshold, and then sending second information, the second information includes connection configuration information and The indication identifier is used to indicate that the receiving node is prohibited from establishing a communication connection with the sending node and/or the receiving node is prohibited from scanning the sending node. In a possible implementation, other nodes that have not successfully established a communication connection with the sending node, such as node 1, node 2, and node 3, may not receive the first information correctly or receive the first information, but establish a communication connection with the sending node. The communication connection fails, so it is possible to prevent or prohibit the above-mentioned nodes from residing in the management range or coverage area of the sending node or establishing a communication connection with the sending node by sending the second information including the connection configuration information and the indication identifier, thereby effectively reducing the number of sending nodes. energy consumption.

In Embodiment 1, the sending node determines that the number of target receiving nodes that have successfully established a communication connection with the sending node reaches the first threshold, and performs the first operation (that is, any one of modes 1-3), which can effectively reduce the energy of the sending node consume.

In a further possible design, please refer to FIG. 10, the above-mentioned first communication method also includes:

S903. The sending node determines that the first condition is met, and continues to send the first information. Correspondingly, the receiving node receives the first information.

It can be understood that the first information in S903 includes connection configuration information, so that the receiving node can establish a communication connection with the sending node after receiving the first information.

In this design, if it is necessary to determine whether to send the first information according to the first condition, before step 901 is executed, the first condition may also be judged first, and if the first condition is met, then step 901 is executed.

In the embodiment of this application, the first condition has many situations, including but not limited to at least one of the following:

1. It is determined that the number of target receiving nodes that have successfully established communication connections with the sending node is less than a first threshold.

2. The communication link between the sending node and any node in the target receiving node is abnormal.

Where the communication link between the sending node and any node in the target receiving node is abnormal, it may be understood that the communication link between any node in the target receiving node is disconnected. Optionally, the abnormality of the communication link may be caused by the abnormality of any node in the target receiving node, for example, if any node in the target receiving node is powered off, the communication link between the arbitrary node and the sending node will be disconnected.

3. Any node in the target receiving node is in a disconnected state.

In this embodiment of the present application, "any node in the target receiving node is in a non-connected state" means that no air interface connection (such as radio resource control (RRC)) has been established between any node in the target receiving node and the sending node. connection, or any resource control (everything resource control, XRC) connection), that is, any node in the target receiving node is in an idle state or an inactive state.

4. The cell associated with any node in the target receiving node is abnormal.

It can be understood that, when the communication method provided by the embodiment of the present application is applied to the BMS, the first condition may be that the battery cell associated with any node in the target receiving node is abnormal. In this embodiment of the present application, "the cell associated with any node in the target receiving node is abnormal" includes, but not limited to, the temperature of the cell associated with any node in the target receiving node exceeds the first preset value, and the voltage exceeds the second preset value. At least one of the set value, the current exceeding the third preset value, or the cell being deformed.

5. The communication resource update of the sending node.

In this embodiment of the present application, the communication resources of the sending node may include but not limited to access resources and common channel parameter configurations. Among them, the access resource includes the time resource and frequency resource configured by the sending node for the receiving node to establish a communication connection, the common channel parameter configuration includes the common channel resource required for the sending node to communicate with the receiving node, and the common channel resource includes time domain , frequency domain, air domain, or any configuration in frequency hopping.

6. The first threshold is updated.

In this embodiment of the present application, the "first threshold" is used to characterize the management capability of the sending node, that is, the number of receiving nodes that can establish a communication connection with the sending node. The first threshold is updated, that is, the management capability of the sending node changes. For example, as the first threshold increases, the number of receiving nodes that can establish communication connections with the sending node increases.

Example 1, please continue to refer to Figure 1, the receiving node takes node 1, node 2, node 3, node 4, node 5, and node 6 as examples, and the first threshold is 4 as an example, if the sending node detects node 5 and node 6. If the communication connection has been successfully established with the sending node, it is determined that the number of target receiving nodes that have successfully established communication connections with the sending node is less than the first threshold, and the sending node sends first information including connection configuration information. Correspondingly, any node among node 1, node 2, node 3, or node 4 receives the first information, and may establish a communication connection with the sending node based on the connection configuration information.

Example 2, please continue to refer to FIG. 1 , take node 1, node 2, node 3, node 4, node 5, and node 6 as examples for receiving nodes, and take 4 as an example for the first threshold. If the sending node detects that node 3, node 4, node 5, and node 6 have successfully established a communication connection with the sending node, but the current communication link between node 4 and the sending node is abnormal, resulting in the successful establishment of a communication connection with the sending node The number of target receiving nodes is less than the first threshold, then the sending node sends first information including connection configuration information. Correspondingly, any one of node 1, node 2, or node 3 receives the first information, and may establish a communication connection with the sending node based on the connection configuration information.

Example 3, please continue to refer to FIG. 1 , take node 1, node 2, node 3, node 4, node 5, and node 6 as examples for receiving nodes, and take 4 as an example for the first threshold. If the sending node detects that node 4, node 5, and node 6 have successfully established communication connections with the sending node, but the current node 6 is in a non-connected state, resulting in the number of target receiving nodes that have successfully established communication connections with the sending node being less than the first threshold, the sending node sends first information including connection configuration information. Correspondingly, any one of node 1, node 2, or node 3 receives the first information, and may establish a communication connection with the sending node based on the connection configuration information.

Example 4, please continue to refer to FIG. 1 , take node 1, node 2, node 3, node 4, node 5, and node 6 as examples for receiving nodes, and take 4 as an example for the first threshold. If any node among node 1, node 2, node 3, node 4, node 5, and node 6 is associated with a battery, any node can be used to report the information of the battery associated with any node to the sending node (For example, at least one of temperature information, voltage information, current information, deformation information or humidity information). If the sending node detects that node 4, node 5, and node 6 have successfully established a communication connection with the sending node, but the battery cell associated with node 6 is abnormal (for example, the temperature exceeds the first preset value, and the voltage exceeds the second preset value). value, current exceeds a third preset value, deformation occurs, or humidity exceeds a fourth preset value), then the sending node sends the first information including connection configuration information. Correspondingly, any one of node 1, node 2, or node 3 receives the first information, and may establish a communication connection with the sending node based on the connection configuration information.

Example 5, please continue to refer to FIG. 1 , take node 1, node 2, node 3, node 4, node 5, and node 6 as examples for receiving nodes, and take 3 as an example for the first threshold. Wherein, the first threshold is determined according to communication resources of the sending node. If the sending node detects that node 4, node 5, and node 6 have successfully established a communication connection with the sending node, but the communication resource of the sending node changes (for example, the access resource increases or the common channel parameter configuration changes), causing the first threshold to change If it is 6, then the number of target receiving nodes that have successfully established communication connections with the sending node is less than the first threshold, and the sending node sends first information including connection configuration information. Correspondingly, any one of node 1, node 2, or node 3 receives the first information, and may establish a communication connection with the sending node based on the connection configuration information.

Example 6, please continue to refer to FIG. 1 , the receiving nodes are Node 1 , Node 2 , Node 3 , Node 4 , Node 5 , and Node 6 as examples, and the first threshold is 3 as an example. If the sending node detects that node 4, node 5, and node 6 have successfully established communication connections with the sending node, but the first threshold becomes 5, then the number of target receiving nodes that have successfully established communication connections with the sending node is less than the first threshold , the sending node sends first information including connection configuration information. Correspondingly, any one of node 2, node 3, or node 4 receives the first information, and may establish a communication connection with the sending node based on the connection configuration information.

In some possible implementation manners, the sending node determines that the number of target receiving nodes that have successfully established communication connections with the sending node does not reach the first threshold within the first preset time period, and performs the second operation. Among them, the second operation has multiple ways to realize it, including but not limited to at least one of the following ways:

Mode 1, reporting abnormal information of the first receiving node.

It can be understood that the first receiving node is a node that fails to establish a communication connection with the sending node within the first preset time period.

In mode 1, it is convenient to handle the abnormality of the first receiving node accordingly, thereby effectively prolonging the service life of the first receiving node.

Mode 2, reporting the abnormality information of the cell associated with the first receiving node.

In mode 2, it is convenient to deal with the abnormality of the battery cell associated with the first receiving node, thereby effectively prolonging the service life of the battery cell associated with the first receiving node.

Exemplarily, the sending node can report the abnormality information of the first receiving node or the abnormality information of the cell associated with the first receiving node to the battery control unit in the BMS, and then the battery control unit can generate corresponding control instructions, and pass the sending node sent to the first receiving node, so that the battery management unit corresponding to the first receiving node performs corresponding abnormal processing on the batteries associated with the first receiving node based on the control instruction (for example, controlling the first receiving node to power off, charge, or discharge any one of them, etc.). Optionally, the battery control unit may also control a display device (for example, a liquid crystal display (liquid crystal display, LCD)) to display the abnormal information of the first receiving node or the abnormal information of the battery associated with the first receiving node. In this way, the user can perceive the abnormal information of the first receiving node or the abnormal information of the battery associated with the first receiving node, so that the user can take corresponding safety measures.

Mode 3, stop sending the first information.

In mode 3, the waste of communication resources of the sending node can be reduced in time, thereby further reducing the energy consumption of the sending node.

Mode 4, adjusting the period for sending the first information.

Exemplarily, the sending node may increase the period for sending the first information. In this way, the waste of communication resources of the sending node can be reduced in time, thereby further reducing the energy consumption of the sending node.

Embodiment two

Please refer to Figure 11. Figure 11 shows the second communication method provided by the embodiment of the present application. This method can be applied to the system architecture shown in Figure 2 or Figure 5. The method includes:

S1101. The sending node sends first information in a first time window. Correspondingly, the first node receives the first information within the first time window.

Wherein, the first information includes first connection configuration information, and the first connection configuration information is used to establish a communication connection between the first node belonging to the first group and the sending node. Correspondingly, after receiving the first information, the first node may establish a communication connection with the sending node based on the first connection configuration information within the first time window.

It can be understood that the first group is the first group formed by the sending node performing group management on the receiving nodes, and the first node is the receiving node in the first group. The first group corresponds to the first time window. In the embodiment of this application, the "first time window" can be defined by one or more of the following information: start time, time offset of start time, deadline, deadline The time offset, period, or window length of time. Further optionally, the start time, the time offset of the start time, the deadline, the time offset of the deadline, the period and the window length can be flexibly configured.

In this embodiment of the present application, the first connection configuration information may include at least one of a communication domain domain name, a communication domain identifier, a layer 2 link identifier, or a physical layer identifier of the sending node.

In a possible implementation manner, the first information is a broadcast message, and the sending node may send the first information in a broadcast form. In another possible implementation manner, the first information is a multicast message, and the sending node may send the first information in a multicast form.

S1102. The sending node determines within the first time window that the number of first target nodes in the first group that currently successfully establish communication connections with the sending node reaches a first threshold, and performs a first operation.

It can be understood that the first threshold is a threshold corresponding to the first time window.

Mode 1, stop sending the first information including the first connection configuration information.

For example, please continue to refer to FIG. 2 , the first nodes in the first group are node 1 , node 2 and node 3 as examples, and the first threshold is 2 as an example. If the sending node detects that node 2 and node 3 have successfully established a communication connection with it, then it is determined that the number of first target nodes that have successfully established a communication connection with the sending node has reached the first threshold, and the sending node stops sending information containing the first connection configuration information. the first message. In this way, stopping sending the first information can effectively reduce the energy consumption of the sending node. In a possible implementation, other nodes that have not successfully established a communication connection with the sending node, such as node 1, may not have received the first information correctly, so it is possible to prevent or prohibit node 1 from sending The management area or coverage area of the node resides or establishes a communication connection with the sending node, further reducing the energy consumption of the sending node.

Mode 2: Send updated first information, where the updated first information does not include first connection configuration information.

It can be understood that, in one design, the updated first information is mainly reflected in that the first connection configuration information is removed relative to the first information including the first connection configuration information. Further, there may be other time- or flow-related differences between the updated first information and the above-mentioned first information including the first connection configuration information, which are not specifically limited in this application.

For example, please continue to refer to FIG. 2 , the first nodes in the first group are node 1 , node 2 and node 3 as examples, and the first threshold is 2 as an example. If the sending node detects that node 2 and node 3 have successfully established a communication connection with them, it is determined that the number of first target nodes that have successfully established communication connections with the sending node has reached the first threshold, and the sending node sends updated first information, The updated first information does not include the first connection configuration information. In this way, sending the updated first information (that is, the first information not including the connection configuration information) reduces the amount of information to be sent by the sending node, and can effectively reduce the energy consumption of the sending node. In a possible implementation, other nodes that have not successfully established a communication connection with the sending node, such as node 1, may not have received the first information correctly, so it is possible to prevent or prohibit the above-mentioned nodes by sending the updated first information 1 Residing in the management range or coverage of the sending node or establishing a communication connection with the sending node, thereby effectively reducing the energy consumption of the sending node.

It should be noted that the updated first information may be received by Node 2 and Node 3 that have successfully established a communication connection with the sending node. At this time, Node 2 and Node 3 continue to maintain the original communication connection and are not affected by the The impact of the updated first message.

Way 3: Send second information, the second information includes first connection configuration information and a first indication, and the first indication is used to instruct the receiving node to establish a new communication connection with the sending node and/or prohibit the receiving node from scanning the sending node.

It should be noted that the above-mentioned first information and second information are both used to carry information (such as first connection configuration information) required for establishing a communication connection between the first node and the sending node, but certain information contained in the first information and the second information Some information elements (such as indicators) are different. For example, when both the first information and the second information are broadcast messages, both the first information and the second message include the first indication, but the first indication in the first information is used to indicate that the receiving node and the sending node are allowed to create new The communication connection and/or allowing the receiving node to scan the sending node, the first indication in the second information is used to indicate that the receiving node is prohibited from creating a new communication connection with the sending node and/or the receiving node is prohibited from scanning the sending node.

For example, please continue to refer to FIG. 2 , the first nodes in the first group are node 1 , node 2 and node 3 as examples, and the first threshold is 2 as an example. If the sending node detects that node 2 and node 3 have successfully established a communication connection with it, then it is determined that the number of first target nodes that have successfully established a communication connection with the sending node has reached the first threshold, and then sends second information, the second information includes The first connection configuration information and the first indication may indicate that the receiving node is prohibited from establishing a communication connection with the sending node and/or the receiving node is prohibited from scanning the sending node. In a possible implementation, other nodes that have not successfully established a communication connection with the sending node, such as node 1, may not have received the first information correctly or received the first information, but failed to establish a communication connection with the sending node, so it may By sending the second information including the connection configuration information and the indicator, the above node 1 is prevented or prohibited from camping in the management range or coverage of the sending node or establishing a communication connection with the sending node, thereby effectively reducing the energy consumption of the sending node.

In a possible implementation manner, if the first node successfully establishes a communication connection with the sending node, the first node does not receive the first information during the remaining time of the first time window, and the time outside the first time window Not receiving the first information; or, receiving updated first information within the remaining time of the first time window, and the updated first information does not include the first connection configuration information; or, receiving within the remaining time of the first time window Receive second information including the first connection configuration information and the first indication.

In a further possible design, please refer to Figure 12, the above-mentioned second communication method also includes:

S1103. The sending node determines that the first condition is satisfied within the first time window, and continues to send the first information. Correspondingly, if the current first node has not successfully established a communication connection with the sending node, the first information is received.

It can be understood that the first information in S1103 includes first connection configuration information, so that the first node may establish a communication connection with the sending node based on the first connection configuration information after receiving the first information.

In this design, if it is necessary to determine whether to send the first information according to the first condition, before step 1101 is executed, the first condition may also be judged first, and if the first condition is met, then step 1101 is executed.

1. It is determined that the number of first target nodes that have successfully established communication connections with the sending node is less than a first threshold.

2. The communication link between the sending node and any node in the first target node is abnormal.

3. Any node in the first target node is in a disconnected state.

4. The cell associated with any node in the first target node is abnormal.

5. The communication resource update of the sending node.

6. The first threshold is updated.

In this embodiment of the present application, the "first threshold" is used to characterize the number of nodes in the first group that are allowed to establish a communication connection with the sending node. The first threshold is updated, that is, the number of first nodes that can establish a communication connection with the sending node in the first group changes.

For other detailed descriptions of the first condition, please refer to the description of the first condition in the first embodiment above, and only need to replace the "target receiving node" in the first embodiment with "the first target node".

For Example 1, please continue to refer to FIG. 2 , the first nodes in the first group are Node 1 , Node 2 and Node 3 as examples, and the first threshold is 3 as an example. If the sending node detects that node 1 and node 2 have successfully established communication connections with the sending node, but the number of first target nodes that have successfully established communication connections with the sending node is less than the first threshold, the sending node sends a message containing the first connection configuration information first information. Correspondingly, node 3 receives the first information, and may establish a communication connection with the sending node based on the first connection configuration information.

Example 2, please continue to refer to FIG. 2 , the first nodes in the first group are node 1 , node 2 and node 3 as examples, and the first threshold is 2 as an example. If the sending node detects that node 1 and node 2 have successfully established a communication connection with the sending node, but the current communication link between node 2 and the sending node is abnormal, the number of first target nodes that have successfully established a communication connection with the sending node is smaller than the first threshold, the sending node sends first information including the first connection configuration information. Correspondingly, node 3 receives the first information, and may establish a communication connection with the sending node based on the first connection configuration information.

For Example 3, please continue to refer to FIG. 2 , the first nodes in the first group are Node 1 , Node 2 and Node 3 as examples, and the first threshold is 2 as an example. If the sending node detects that node 1 and node 2 have successfully established a communication connection with the sending node, but the current node 1 is in a non-connected state, resulting in the number of first target nodes currently successfully establishing a communication connection with the sending node being less than the first threshold, then The sending node sends first information including first connection configuration information. Correspondingly, node 3 receives the first information, and may establish a communication connection with the sending node based on the first connection configuration information.

For example 4, please continue to refer to FIG. 2 , the first nodes in the first group are node 1 , node 2 and node 3 as examples, and the first threshold is 2 as an example. If any node among node 1, node 2, and node 3 is associated with a battery cell, any node can be used to report the information of the battery cell associated with any node to the sending node (for example, temperature information, voltage information, current information, or at least one of humidity information). If the sending node detects that node 1 and node 2 have successfully established a communication connection with the sending node, but the cell associated with node 2 is abnormal (for example, the temperature exceeds the first preset value, the voltage exceeds the second preset value, the current exceeds the If the third preset value or the humidity exceeds at least one of the fourth preset value), the sending node sends the first information including the first connection configuration information. Correspondingly, node 3 receives the first information, and may establish a communication connection with the sending node based on the first connection configuration information.

For Example 5, please continue to refer to FIG. 2 , the first nodes in the first group are Node 1 , Node 2 , and Node 3 as examples, and the first threshold is 2 as an example. Wherein, the first threshold is determined according to communication resources of the sending node. If the sending node detects that node 1 and node 2 have successfully established a communication connection with the sending node, but the access resource of the sending node increases or the configuration of the common channel parameters changes, causing the first threshold to become 3, then the current communication with the sending node is successfully established The number of connected first target nodes is less than a first threshold, and the sending node sends first information including first connection configuration information. Correspondingly, node 3 receives the first information, and may establish a communication connection with the sending node based on the first connection configuration information.

Example 6, please continue to refer to FIG. 2 , the first nodes in the first group are node 1 , node 2 and node 3 as examples, and the first threshold is 2 as an example. If the sending node detects that

nodes

1 and 2 have successfully established communication connections with the sending node, but the first threshold becomes 3, then the number of first target nodes that have successfully established communication connections with the sending node is less than the first threshold, and the sending node Send first information including first connection configuration information. Correspondingly, node 3 receives the first information, and may establish a communication connection with the sending node based on the first connection configuration information.

In some possible implementation manners, within the first time window, the sending node determines that the number of first target nodes that have successfully established communication connections with the sending node does not reach the first threshold, and performs the second operation. Among them, the second operation has multiple ways to realize it, including but not limited to at least one of the following ways:

Mode 1, reporting abnormal information of the third node.

In mode 1, it is convenient to deal with the abnormality of the third node, thereby effectively prolonging the service life of the third node.

Mode 2, reporting the abnormal information of the batteries associated with the third node.

In mode 2, it is convenient to deal with the abnormality of the battery cell associated with the third node, thereby effectively prolonging the service life of the battery cell associated with the third node.

It can be understood that the third node is a node in the first group that fails to establish a communication connection with the sending node within the first time window.

In some possible embodiments, the sending node may report the abnormality information of the third node or the abnormality information of the batteries associated with the third node to the battery control unit in the BMS. Optionally, the battery control unit may also control a display device (for example, LCD) to display the abnormal information of the third node or the abnormal information of the battery associated with the third node. In this way, the user can perceive the abnormal information of the third node or the abnormal information of the battery associated with the third node, so that the user can take corresponding safety measures.

Mode 3, stop sending the first information.

Mode 4, adjusting the period for sending the first information.

Exemplarily, the sending node can increase the period for sending the first information within the first time window, so that the waste of communication resources of the sending node can be reduced in time, thereby further reducing the energy consumption of the sending node.

Similarly, the sending node can manage the second node of the second group, and can send the third information within the second time window, the third information includes the second connection configuration information, and the second connection configuration information is used to belong to the second group The second node establishes a communication connection with the sending node.

Exemplarily, referring to FIG. 13, the process for the sending node to manage the second node includes:

S1301. The sending node sends third information within a second time window. Correspondingly, the second node receives the third information within the second time window.

Wherein, the third information includes second connection configuration information, and the second connection configuration information is used for establishing a communication connection between the second node belonging to the second group and the sending node. Correspondingly, after receiving the third information, the second node may establish a communication connection with the sending node based on the second connection configuration information within the second time window.

It can be understood that the second group is the second group formed by the sending node performing group management on the receiving nodes, and the second node is the receiving node in the second group. The second group corresponds to the second time window. In the embodiment of this application, the "second time window" can be defined by one or more of the following information: start time, time offset of start time, deadline, deadline time offset, period, or window length.

In this embodiment of the present application, there is no overlapping time resource between the first time window and the second time window, and/or there is no same node in the first group and the second group. And, in the embodiment of the present application, "there is no overlapping time resource between the first time window and the second time window", it can be understood that the time resources corresponding to the first time window and the second time window can be continuous (as shown in Figure 14 shown), or there is a preset interval (as shown in FIG. 15 ), which is not specifically limited in this embodiment of the present application.

In this embodiment of the present application, the second connection configuration information includes at least one of a communication domain domain name, a communication domain identifier, a layer 2 link identifier, or a physical layer identifier.

S1302. When the sending node determines within the second time window that the number of second target nodes that currently successfully establish communication connections with the sending node in the second group reaches a second threshold, perform a third operation.

In this embodiment of the application, there are multiple ways to implement the third operation, including but not limited to any of the following ways:

Mode 1, stop sending the third information including the second connection configuration information.

Mode 2: Send updated third information, where the updated third information does not include the second connection configuration information.

It can be understood that, in one design, the updated third information is mainly reflected in that the second connection configuration information is removed relative to the third information including the second connection configuration information. Further, there may be other time- or process-related differences between the updated third information and the above-mentioned third information including the second connection configuration information, which are not specifically limited in this application.

Mode 3: Send fourth information, where the fourth information includes second connection configuration information and a second indication, and the second indication is used to instruct the receiving node to establish a communication connection with the sending node and/or prohibit the receiving node from scanning the sending node.

It should be noted that both the third information and the fourth information above carry the information (such as the second connection configuration information) required by the fourth node to establish a communication connection with the sending node, but some of the information contained in the third information and the fourth information The information units (such as the second indicator) are different. For example, when both the third information and the fourth information are broadcast messages, both the third information and the fourth message include the second indicator, but the second indicator in the third information is used to indicate that the second node and the sending node are allowed Create a communication connection and/or allow the second node to scan the sending node, and the second indication in the fourth information is used to indicate that the receiving node is prohibited from establishing a communication connection with the sending node and/or the receiving node is prohibited from scanning the sending node.

It should be noted that, in this embodiment, the contents of the first information and the third information are the same, and the contents of the second information and the fourth information are the same. The difference is that the first information and the second information are sent within the first time window, and the third information and the fourth information are sent within the second time window.

It should be noted that, the above-mentioned first indicator, the indicator and the indicator in the first implementation are all used to indicate that the receiving node is prohibited from creating a new communication connection with the sending node and/or the receiving node is prohibited from scanning the sending node.

In S1302, when the sending node determines within the second time window that the number of second target nodes currently successfully establishing a communication connection with the sending node in the second group reaches the second threshold, the third operation (i.e. mode 1 to mode 3) is executed. Any one of the above), can effectively prevent or prohibit the second node that has not successfully established a communication connection with the sending node to reside in the management range or coverage of the sending node or establish a communication connection with the sending node, thereby effectively reducing the energy of the sending node consume.

S1303. The sending node determines that the second condition is satisfied within the second time window, and sends the third information. Correspondingly, if the current second node has not successfully established a communication connection with the sending node, the third information is received.

It can be understood that the third information in S1303 includes the second connection configuration information, so that the second node can establish a communication connection with the sending node based on the second connection configuration information after receiving the third information.

In this design, if it is necessary to determine whether to send the first information according to the second condition, before step 1301 is executed, the second condition may be judged first, and if the second condition is met, then step 1301 is executed.

In this embodiment of the application, the second condition has many situations, including but not limited to at least one of the following:

1. It is determined that the number of second target nodes that have successfully established communication connections with the sending node is less than a second threshold.

2. The communication link between the sending node and any node in the second target node is abnormal.

3. Any node in the second target node is in a disconnected state.

4. The cell associated with any node in the second target node is abnormal.

5. The communication resource update of the sending node.

6. The second threshold is updated.

In this embodiment of the present application, the "second threshold" is used to characterize the number of nodes in the second group that are allowed to establish a communication connection with the sending node. The second threshold is updated, that is, the number of second nodes that can establish a communication connection with the sending node in the second group changes.

For other detailed descriptions of the first condition, please refer to the description of the first condition in the first embodiment above, and only need to replace the "target receiving node" in the first embodiment with "the second target node".

Example 1, please continue to refer to FIG. 2 , the second nodes in the second group are nodes 4 , 5 and 6 as examples, and the first threshold is 3 as an example. If the sending node detects that node 4 and node 5 have successfully established communication connections with them, but the number of second target nodes that have successfully established communication connections with the sending node is less than the second threshold, the sending node sends a third node containing the second connection configuration information. information. Correspondingly, node 3 receives the third information, and may establish a communication connection with the sending node based on the second connection configuration information.

In Example 2, the second nodes in the second group are Node 4, Node 5, and Node 6 as examples, and the first threshold is 2 as an example. If the sending node detects that nodes 4 and 5 have successfully established communication connections with them, but the current communication link between node 4 and the sending node is abnormal, resulting in the number of second target nodes that have successfully established communication connections with the sending node being less than the first two thresholds, the sending node sends the third information, and the third information includes the second connection configuration information. Correspondingly, node 6 receives the third information, and may establish a communication connection with the sending node based on the second connection configuration information.

In Example 3, the second nodes in the second group are Node 4, Node 5, and Node 6 as examples, and the first threshold is 3 as an example. If the sending node detects that node 4 and node 5 have successfully established a communication connection with it, but the current node 4 is in an unconnected state, resulting in the number of second target nodes currently successfully establishing a communication connection with the sending node being less than the second threshold, the sending node Send third information, where the third information includes second connection configuration information. Correspondingly, node 6 receives the third information, and may establish a communication connection with the sending node based on the second connection configuration information.

For Example 4, please continue to refer to FIG. 2 , the second nodes in the second group are Node 4 , Node 5 and Node 6 as examples, and the first threshold is 3 as an example. If any node among node 4, node 5, and node 6 is associated with a battery cell, the node can be used to report the information of the battery cell associated with the node to the sending node. If the sending node detects that nodes 4 and 5 have successfully established a communication connection with the sending node, but the battery cell associated with node 4 is abnormal, the sending node disconnects the communication connection between node 4 and the sending node, and sends a third information, the third information includes the second connection configuration information. Correspondingly, node 6 receives the third information, and may establish a communication connection with the sending node based on the second connection configuration information.

Example 5, please continue to refer to FIG. 2 , the second nodes in the second group are taken as nodes 4 , 5 and 6 , and the first threshold is 2 as an example. Wherein, the second threshold is determined according to communication resources of the sending node. If the sending node detects that node 4 and node 5 have successfully established a communication connection with the sending node, but the access resource of the sending node increases or the configuration of the common channel parameters changes, causing the second threshold to become 3, then the current communication with the sending node is successfully established When the number of connected second target nodes is less than the second threshold, the sending node sends third information, where the third information includes second connection configuration information. Correspondingly, node 6 receives the third information, and may establish a communication connection with the sending node based on the second connection configuration information.

Example 6, please continue to refer to FIG. 2 , the second nodes in the second group are taken as nodes 4 , 5 and 6 , and the first threshold is 2 as an example. If the sending node detects that nodes 4 and 5 have successfully established communication connections with the sending node, but the second threshold becomes 3, then the number of second target nodes that have successfully established communication connections with the sending node is less than the second threshold, and the sending node Send third information, where the third information includes second connection configuration information. Correspondingly, node 6 receives the third information, and may establish a communication connection with the sending node based on the second connection configuration information.

It should be noted that the first connection configuration information, the second connection configuration information, and the connection configuration information in the first implementation above are all key information for establishing a communication connection between the sending node and the receiving node. Wherein, the first connection configuration information is used for the first node belonging to the first group to establish a communication connection with the sending node, the second connection configuration information is used for the second node belonging to the second group to establish a communication connection with the sending node, and the connection configuration information is used for Establish communication connections between all receiving nodes and sending nodes.

Similarly, within the second time window, the sending node determines that the number of second target nodes that have successfully established communication connections with the sending node does not reach the second threshold, and performs a fourth operation.

Among them, the fourth operation has multiple ways of implementation, including but not limited to at least one of the following ways:

Mode 1, reporting abnormal information of the fourth node. In mode 1, it is convenient to deal with the abnormality of the fourth node accordingly, thereby effectively prolonging the service life of the fourth node.

It can be understood that the fourth node is a node in the second group that fails to establish a communication connection with the sending node within the second time window.

Mode 2, reporting the abnormal information of the batteries associated with the fourth node. In mode 2, it is convenient to deal with the abnormality of the battery cell associated with the fourth node, thereby effectively prolonging the service life of the battery cell associated with the fourth node.

Exemplarily, the sending node can report the abnormal information of the fourth node or the abnormal information of the batteries associated with the fourth node to the battery control unit in the BMS, and then the battery control unit can generate corresponding control instructions and send them to The fourth node further enables the battery management unit corresponding to the fourth node to perform corresponding abnormal processing on the batteries associated with the fourth node based on the control instruction (please refer to the foregoing description). Optionally, the battery control unit may also control a display device (for example, LCD) to display the abnormal information of the fourth node or the abnormal information of the battery associated with the fourth node. In this way, the user can perceive the abnormal information of the fourth node or the abnormal information of the battery associated with the fourth node, so that the user can take corresponding safety measures.

Mode 3, stop sending the third information. In mode 3, the waste of communication resources of the sending node can be reduced in time, thereby further reducing the energy consumption of the sending node.

Mode 4, adjusting the period for sending the third information. In a possible implementation manner, the sending node may increase a period for sending the third information within the second time window. In this way, the waste of communication resources of the sending node can be reduced in time, thereby further reducing the energy consumption of the sending node.
