Embodiment 1

[0027] figure 1 It is a flow chart of a method for networking and communication in the electric power Internet of Things provided by an embodiment of the present invention. like figure 1 As shown, it mainly includes the following steps:

[0028] Step 11, the base station or the online node receives the network access request sent by the offline node, and exchanges messages with the offline node N times.

[0029] The communication network established in this embodiment includes base stations and collection nodes (collectors). Stay online. Wherein, the base station and the online node have the right to accept the network access request of the offline node.

[0030] In this embodiment, a network access strategy of multiple requests and responses is used to evaluate the reliability and stability of the link. That is, when an offline node regularly sends a FIND message to request to join the network before joining the network, when the base station or an online node (hereinaft...

Embodiment 2

[0040] In order to facilitate understanding of the present invention, below in conjunction with Figure 2-3 for further clarification. In this embodiment, the process of automatically establishing a communication network begins with the network including only base stations. like image 3 As shown, it mainly includes the following steps:

[0041] Step 21, the base station receives the network access request sent by the offline node.

[0042] In the initial state of network formation, the network only includes base stations, and the base stations are permanently online (with the right to accept network access requests from offline nodes). When the collector is powered on, it will act as an offline node. Its first task is to find a parent node to join the network. Therefore, it will periodically send a FIND message to request to join the network until it receives a reply message.

[0043] At this time, only the base station is in the online state in the network, and after rec...

Abstract

The invention discloses a method of networking and communicating in an electric power internet of things. According to the method of networking and communicating in the electric power internet of things, a base station or an on-line node receives a network access request sent by an off-line node and conducts N times of redundancy long message interaction with the off-line node; if the N times of redundancy long message interactive are all successful, the off-line node accesses the network as a child node of the base station or the on-line node conducting the message interaction with the off-line node; the child node sends path information to the base station, and the base station generates a routing table according to the received path information and conducts network maintenance and down-link data communication according to the routing table; and the method further adopts application layer routing technology to conduct up-link communication. By means of the method of networking and communicating in the electric power internet of things, the networking process is simplified, the stability and reliability of networking are improved at the same time, the load of the network is lightened, and the success rate of communication is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for networking and communication in the electric power internet of things. Background technique [0002] Power Internet of Things refers to the IoT network currently used in power systems. It is mainly used to network power information collection or monitoring terminals, and finally present the information of these terminal devices on the Internet in real time, which is convenient for power company management and power user inquiries. Power Internet of Things is one of the earliest applications of the Internet of Things. Power information terminals can be directly connected to the Internet through their own network interfaces (GPRS, Ethernet, optical fiber interfaces, etc.). To collect terminal nodes, it is still necessary to establish a local area network and exchange information with the Internet through base stations (concentrators). [0003] In the prior art, the networkin...
