Power edge gateway device and method for storing sensory data on chain based on the device

Abstract

The invention discloses a power edge gateway device, which adopts block chain technology to realize communication authentication and data transmission encryption of the gateway. As a local information aggregation and processing device, the edge gateway device can not only form a local blockchain network with various local power sensing terminal equipment, but also build a regional blockchain network with other edge gateways and power management platforms. As the key node of these two blockchains, the edge gateway realizes the authentication of identity legitimacy among power sensing terminal devices, the storage and control of blockchain ledgers for key data by virtue of the immutability and traceability of blockchain technology. The deployment and implementation of blockchain transactions with linkage functions, as well as safe and reliable data interaction and other functions. The invention also discloses an uplink storage method for sensing data based on the power edge gateway device.

Description

technical field [0001] The invention relates to the field of electrical engineering science, in particular to a power edge gateway device and an uplink storage method for sensing data based on the device. Background technique [0002] With the effective integration of the new generation of information technology such as the Internet of Things and the Internet with the smart grid, the traditional power grid is gradually transformed into a two-way interactive service model of the smart grid. Information and other content, so as to make reasonable arrangements for power operation and maintenance. Compared with the traditional power grid, the new smart grid has the characteristics of heterogeneous communication network, ubiquitous network security protection boundary, and diversified business security access requirements, which directly increases power information leakage, illegal equipment access and equipment management. A series of security risks such as loss of control have...

Problems solved by technology

[0005] At present, power edge gateways generally implement device authentication and communication encryption through software encryption algorithms, but encryption algorithms have certain requirements for device resources, and power sensing terminal devices are generally resource-constrained devices. Therefore, the relationship between edge gateways and sensing devices Communication security is generally not suitable for encryption algorithms with high complexity

Some power transmission edge gateways implement device authentication and data communication encryption functions by adding additional hardware encryption methods such as security encryption chips or security devices, but hardware encryption will increase device cost and power consumption, and at the same time, hardware encryption methods are not applicable Sensing terminal equipment
