step S1: taking an established network between a master control node and each slave control node as a first network;
step S2: acquiring an identity of a battery pack;
step S3: constructing an intrusion node, and transmitting the identity to the intrusion node so that the intrusion node performs the following operations:
step S301: accessing a database according to the identity, and acquiring network access rights and an upgrade package of a first network from the database;
step S302: establishing network connection with the master control node and each slave control node according to the network access authority to generate a second network;
step S303: and sending an upgrade package to the master control node and each slave control node through a second network so that the master control node and each slave control node are upgraded according to the upgrade package.
Fig. 2 is a system block diagram of a network intrusion type node upgrade method according to the present embodiment.
For step S1, in the wireless battery management system, there is a master node and several slave nodes (i.e., slave node No. … in fig. 2, slave node No. n). The master control node establishes data communication connection with the slave control No. 1 node and the slave control No. 2 node … slave control No. n node respectively, and the network A constructed by the master control node and each slave control node connected with the master control node is the first network.
For step S2, the ID identifier of the battery pack (i.e. the ID identifier of the battery pack) is obtained by the code scanner. Optionally, in one aspect, an operator may use a code scanning gun to scan the code of the battery pack where the master control node and each slave control node are located, so as to obtain the ID identifier of the battery pack. On the other hand, non-manual equipment such as a program control mechanical arm and the like can be used for replacing operators to scan the code of the battery pack where the master control node and each slave control node are located by using the code scanning gun so as to acquire the ID identification number of the battery pack.
And for the step S3, constructing an intrusion node, and transmitting the battery pack ID identification number acquired by the code scanning gun in the step S2 to the constructed intrusion node.
For step S301: the intrusion node accesses a cloud database of the wireless battery management system according to the acquired battery pack ID identification number, and acquires the network access authority of the network A (namely the first network) from the cloud database. Meanwhile, the intrusion node acquires an upgrade package for upgrading each node from the cloud database according to the acquired battery package ID identification number.
For step S302: according to the acquired access rights of the network A, the intrusion node respectively establishes data communication connection with the master control node, the slave control No. 1 node and the slave control No. 2 node … slave control No. n node, and establishes a network B (namely the second network) among the intrusion node, the master control node, the slave control No. 1 node and the slave control No. 2 node … slave control No. n node, so that the intrusion of the intrusion node to the network A is completed, and meanwhile, the construction of the network B containing the intrusion node is completed.
For step S303: in a preferred embodiment, the sending, by the second network, an upgrade packet to the master node and each slave node, so that the master node and each slave node perform an upgrade according to the upgrade packet, includes: acquiring the MAC address of each slave node, and sending an upgrade packet to each slave node according to the MAC address of each slave node so that each slave node finishes the upgrade of the own node after receiving the upgrade packet; and acquiring the MAC address of the main control node, and sending an upgrade packet to the main control node according to the MAC address of the main control node, so that the main control node finishes the upgrade of the main control node after receiving the upgrade packet.
Specifically, the intrusion node firstly acquires the MAC addresses of the slave No. 1 node and the slave No. 2 node … slave No. n node, and based on the acquired MAC addresses of the slave nodes, sends the upgrade packet to the MAC address corresponding to each slave node, so that the upgrade packet can be accurately sent to the corresponding slave node, and the slave node can complete the upgrade of the own node after acquiring the upgrade packet. After the upgrade of all the slave nodes is finished, the intrusion node exits the data interaction with the slave nodes. The intrusion node acquires the MAC address of the main control node, and sends an upgrade packet to the main control node according to the MAC address of the main control node, so that the main control node finishes the upgrade of the self node after receiving the upgrade packet. After the upgrade of the main control node is completed, the intrusion node exits the data interaction with the main control node. Preferably, after each slave control node and the master control node complete the upgrade of the own node according to the received upgrade packet, feedback information of the upgrade completion is sent to the intrusion node, so that the intrusion node can monitor the upgrade condition of each slave control node and the master control node.
In a preferred embodiment, further comprising: when a network connection is established with the master control node and each slave control node according to the network access authority to generate a second network, the first network is closed; and closing the second network after the main control node and each slave control node finish upgrading according to the upgrading packet, and restarting the first network.
Specifically, in step S302, after the network B (i.e., the second network) is established between the slave n nodes according to the intrusion node, the master node, the slave 1 node, and the slave 2 node …, the network a (i.e., the first network) is closed, and only the network B is opened. After the intrusion node finishes upgrading the master control node and all the slave control nodes in step S303, the network B is closed and the network a is restarted.
In a preferred embodiment, after restarting the first network, further comprising: and monitoring the network quality of the first network, and deleting the second network after the network quality of the first network is monitored to be normal.
Specifically, after restarting the network a (i.e., the first network described above), the network quality of the network a needs to be monitored. By detecting the received signal strength (Received Signal Strength Indicator, abbreviated as RSSI) of the network a, it is determined whether the received signal strength of the network a after restarting is not lower than the received signal strength of the initial established network a in step S1, and if not lower than the received signal strength of the initial established network a in step S1, the network quality of the network a is considered to be normal. Optionally, the network quality of the network a may be detected by the PDR network security model, and the network quality of the network a may be determined according to the values of the indexes of the PDR network security model in the process of detecting the network a. When the network quality of the network A is monitored to be normal, namely the network A can be used normally, the intrusion node is completely exited, and the network B containing the intrusion node is deleted.
