System and method for network node authentication, reconfiguration and data transmission

Abstract

The embodiment of the invention provides a system and method for network node authentication, reconfiguration and data transmission of a power distribution body area network, and belongs to the field of power distribution Internet of Things. The distribution body area network node authentication system comprises a sensing node, an aggregation node and an intelligent terminal. The sensing node is used for sending a newly added node registration request to the aggregation node, and according to first notification information returned by the aggregation node in response to the newly added node registration request, selecting the nearest aggregation node j to send a first registration request. The aggregation node j is used for authenticating the sensing node according to the first registration request. The power distribution body area network node authentication system is beneficial for improving the automation and intelligence level of power data acquisition, transmission and processing.

Description

technical field [0001] The invention relates to the field of power distribution Internet of Things, in particular to a system and method for network node authentication, reconfiguration and data transmission of power distribution body area network for peripheral access communication of power distribution Internet of Things. Background technique [0002] As a key technology of the Internet of Things technology, wireless communication provides a reliable and powerful guarantee for the interconnection of people and things in the Internet of Things, and then transforms the centralized and one-way power grid into a power grid for consumer interaction. From the perspective of communication range, the wireless communication technology of power Internet of Things constructed with the concept of Internet can be divided into local area network and wide area network. The local area network includes information transmission such as energy collection, aggregation and sharing, internal en...

Problems solved by technology

[0006] However, the existing data collection and networking transmission methods still have the following defects: Many power equipment in the power backbone network are fully enclosed metal structures. If manual collection is used to perceive their internal states, it will lead to increased labor costs and limit the real-time data collection. Restricting the effective acquisition of perception layer data in the power Internet of Things scenario

On the other hand, although BLE technology has a small number of pilot applications, it is limited by the closed metal structure of power equipment, some signals are shielded and cannot be transparently transmitted, and the internal data of power distribution network equipment cannot be transmitted in a timely and effective manner, and the transmission cost and high power consumption, resulting in insufficient timeliness of node device data transmission in the power Internet of Things scenario
