Transformer substation full-internet-of-things system based on wireless sensor and edge gateway

Abstract

The invention belongs to the technical field of transformer substation internet-of-things system structures and design thereof, and particularly relates to a transformer substation full-internet-of-things system based on a wireless sensor and an edge gateway. The system comprises a micro-power wireless sensor, an intelligent controller, an intelligent electric meter and an edge Internet of Thingsgateway. The micro-power wireless sensor communicates with the edge Internet of Things gateway in a LoRa micro-power wireless communication mode; the intelligent controller communicates with the edgeInternet of Things gateway in an RS485 mode; the intelligent electric meter communicates with the edge Internet of Things gateway through high-speed power line carrier communication; and the intelligent electric meter supports active reporting of a power failure event while acquiring power consumption information; the edge Internet of Things gateway is divided into a hardware layer, an operating system layer, a basic function layer and an edge service layer. According to the system, the information is searched through the edge gateway, and the information is processed through edge computing, so that the problem that massive computing is difficult to access in a centralized computing mode is solved. Compared with the traditional on-line monitoring system, the cost is greatly reduced by using the novel micro-power consumption wireless sensor.

Description

technical field [0001] The invention belongs to the technical field of substation IoT system structure and design thereof, and in particular relates to a substation full IoT system based on a wireless sensor and an edge gateway. Background technique [0002] From the bottom to the top, the ubiquitous power Internet of things can be divided into four layers: perception layer, network layer, platform layer and application layer. Among them, the perception layer collects the state parameters of power equipment and uploads the data to the network nodes, which is an important way for the Internet of Things to obtain information. The ability and quality of information collected by sensors will directly affect the processing and transmission of information by the edge IoT gateway computing unit. Its characteristics play a pivotal role in the entire ubiquitous power Internet of Things application system. However, at present, the development of the perception layer technology of the...
