Specifically, the central server allocates fixed tags to all terminal nodes within the coverage area of the central server, for example, when the terminal node 1 joins the internet of things system, the terminal node 1 gets the tag a after starting, and then the terminal node 1 uses the tag a to communicate with the outside world in the whole internet of things system.
Wherein, the tag is a physically unique code, for example, the bluetooth device will obtain a tag of BLE + device number.
Each terminal node in the internet of things is distributed with a fixed label, and the terminal nodes take the fixed labels as own identity information in all network transmission processes, so that the terminal nodes can hide own real identities.
In some embodiments, the terminal node encrypts and hides its own real identity information, such as a fixed tag, by using a key encryption algorithm, it can be understood that a node encryption technology is used between the management node and the central server to perform second layer encryption, and a double-layer encryption technology is used to ensure privacy of the terminal node, the management node, and the central server.
The encryption algorithm may be an encryption method such as symmetric encryption or asymmetric encryption, which is not listed here.
And the terminal node uses the label to communicate with the outside world in the whole internet of things system.
Based on the Internet of things system, a communication method of the Internet of things is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a communication method of the internet of things according to an embodiment of the present application. The communication method of the Internet of things can be applied to the Internet of things system in fig. 1 and can also be applied to a central server of the Internet of things, so that a communication link between a terminal node and a management node is effectively established, and the time loss of the terminal node and the management node on an authentication mechanism is reduced.
As shown in fig. 2, the communication method of the internet of things specifically includes steps S101 to S103.
S101, receiving request data sent by a terminal node; the request data includes tag information of the terminal node.
When the terminal nodes need to communicate, the terminal nodes send request data to the central server, and the request data comprise the label information of the terminal nodes.
The tag information of the terminal node is a physical unique code, for example, the terminal node is a specific household appliance, such as an intelligent air conditioner, and then, the tag information may be a tag of BLE + air conditioner number.
Receiving request data sent by a terminal node, wherein if the request data of the intelligent air-conditioning equipment is received, the request data comprises tag information of the intelligent air-conditioning equipment: BLE + air conditioner number.
S102, determining a first management node with the shortest distance to the terminal node in the plurality of management nodes according to the request data.
Because in the whole internet of things system, a plurality of management nodes and a plurality of terminal nodes exist, for example, the internet of things of the community is taken as an example, in a community range, a plurality of families exist, each family has one Bluetooth device as a management node, and the intelligent household appliances in each family are taken as terminal nodes. Certainly, the internet of things is not limited to community internet of things, and can also be industrial internet of things, and the corresponding management node and the corresponding terminal node are also related to the industrial internet of things.
As shown in fig. 3, fig. 3 is a schematic flowchart of a process of determining, according to the request data, a first management node that is shortest in distance from the end node among the plurality of management nodes, where when the central server receives the request data sent by the end node, the determining, by the central server, the first management node that is shortest in distance from the end node among the plurality of management nodes according to the request data may include:
s21, sending the request command corresponding to the request data to a plurality of management nodes, so that the management nodes determine the transmission time length of the request command when receiving the request command, and return the transmission time length.
In some embodiments, the central server sends the request command corresponding to the request data to a plurality of management nodes, for example, the central server sends the request command corresponding to the request data to a plurality of management nodes within a community range, and each management node determines a transmission duration of the request command when receiving the request command, and then transmits the transmission duration back to the central server.
In some embodiments, determining the transmission duration of the request command may be calculated according to the time when the request command is sent and the time when the management node receives the request command. For example, when the management node 1 receives the request data, the time from the query of the request data to the initiation of the request by the terminal node 1 is recorded, and when the management node receives the request data, the time from the receipt of the request data is recorded, and the transmission duration of the request command is obtained according to the difference between the time from the initiation of the request and the time from the receipt of the request data.
And S22, determining a first management node with the shortest distance to the terminal node in the plurality of management nodes according to the transmission time length of each management node.
In some embodiments, after receiving the transmission duration of each management node, the central server compares the transmission durations of the management nodes, for example, the transmission duration of the management node 1 is smaller than the transmission duration … … of the management node 2, so as to determine that the management node with the shortest transmission duration is the management node 1, that is, the management node 1 has the shortest distance to the terminal node among the plurality of management nodes and serves as the first management node.
S103, sending the request data to the first management node, so that the first management node generates an IP relation corresponding table between the terminal node and the first management node based on the request data, and communication between the terminal node and the first management node is completed.
In some embodiments, after determining the first management node, the central server sends request data to the first management node, so that the first management node generates an IP relationship correspondence table between the terminal node and the first management node based on the request data, and completes communication between the terminal node and the first management node.
Specifically, as shown in fig. 4, fig. 4 is a schematic flowchart of a process of generating an IP relationship correspondence table, and sending the request data to the first management node, so that the first management node generates the IP relationship correspondence table between the terminal node and the first management node based on the request data, and completes communication between the terminal node and the first management node, where the process may include:

Specifically, after a first management node with the shortest distance to a terminal node is determined by a central server, request data is sent to the first management node, the first management node reads tag information and a device number of the terminal node in the request data after receiving the request data, and obtains the device number of the first management node, and the first management node generates an IP relationship correspondence table between the terminal node and the first management node based on the device number of the first management node, the tag information of the terminal node and the device number of the terminal node, so that some device information and tag information of the terminal node are managed correspondingly with the device information of the first management node.
It can be understood that the IP relationship correspondence table further stores an IP address assigned to the terminal node by the first management node, so that the terminal node can communicate.
And after the first management node establishes the IP relation corresponding table, the IP relation corresponding table is transmitted back to the central server for backup.
It will be appreciated that there is a device number for both the end node and the management node. The fixed label in the equipment node 1 is the management name of the equipment at the server side; the management node also carries out unique equipment number identification according to the characteristics and the equipment number of the management node.

Specifically, after receiving the IP relationship correspondence table, the central server adds the tag information of the terminal node and the device number of the terminal node in the IP relationship correspondence table between the terminal node and the first management node to the current gateway topology, thereby completing the communication between the terminal node and the first management node.
In some embodiments, for the management of the terminal node, the management node stores the IP relationship correspondence table in the local area network, and only exposes the central server in the external network, thereby avoiding the IP address of the terminal node from being attacked, greatly reducing the probability of being attacked, and improving the security.
After the communication of the terminal nodes is completed, the same communication protocol is observed between the management node and the terminal nodes, the communication protocol can be any one of Bluetooth, zigbee, wifi, lora and NB-IoT protocols, different management nodes can adopt different protocols, the compatibility of the whole system in the aspect of communication is greatly enhanced, and the carrying capacity of the system is expanded.
It should be emphasized that, in order to further ensure the privacy and security of the IP mapping table, the IP mapping table may also be stored in a node of a blockchain.
The embodiment provides a communication method of an internet of things, in which a central server is added in an internet of things system, when a terminal node communicates with a management node, the central server receives request data sent by the terminal node to be communicated, determines a first management node with the shortest distance from the terminal node among a plurality of management nodes according to the request data, and sends the request data to the first management node, so that the first management node generates an IP relationship correspondence table between the terminal node and the first management node based on the request data, and completes communication between the terminal node and the first management node. The central server is used for determining the management node closest to the terminal node, and the management node is used for establishing and maintaining an IP relation corresponding table between the terminal node and the management node, so that a communication link between the terminal node and the management node is established, and the time loss of the terminal node and the management node on an authentication mechanism is reduced.

when an interrupt instruction of the terminal node is received, the communication between the terminal node and the first management node is disconnected;
and when a starting instruction of the terminal node is received, inquiring a first management node corresponding to the equipment number of the management node according to the IP relation corresponding table so as to establish communication between the terminal node and the first management node.
In some embodiments, after the communication of the terminal node is completed, if the terminal node is damaged, the communication may be interrupted, and at this time, the central server receives an interruption instruction of the terminal node and disconnects the communication between the terminal node and the first management node.
And when the terminal nodes are repaired and can be normally used, the terminal nodes are started, and when the central server receives a starting instruction of the terminal nodes, the central server inquires a first management node corresponding to the equipment number of the management node according to the IP relation corresponding table so as to establish communication between the terminal nodes and the first management node, thereby realizing the data forwarding service of the terminal nodes.
