0 Preface

       5G technology, the fifth-generation mobile communication technology, is a new generation of cellular mobile communication technology that can achieve wide channel bandwidth and large-capacity MIOL. 5G technology makes the connection between things more extensive and convenient, and accelerates the process of building the power Internet of Things application level. The establishment of the 5G technology-based power metering device to monitor the Internet of Things provides a feasible solution for tracing the source of faults of the power metering device and improving the quality and efficiency of the power metering device.

 

1 Design of application scheme

     From the perspective of modern Internet of Things technology, the monitoring of electric energy metering devices based on ubiquitous power Internet of Things technology includes 4 levels: perception layer, network layer, platform layer, and application layer, and data communication is carried out through 5G network. Through the perception layer, network layer and platform layer carrying monitoring data sharing and basic support for the construction content in two directions, comprehensive monitoring is achieved within the metering device (measuring secondary loop, meter) and external (outside the metering device itself).

1.1 Perception layer

       The monitoring facilities of electric energy metering devices should realize standardized and unified access to terminals, comprehensively promote physical ID, and resource sharing such as communication and computing, and realize data integration and edge intelligence at the source.

1.1.1 Unified Awareness Access

       The perception equipment access management system will use technical means to enforce relevant regulations, guide unified terminal standards, promote cross-professional data collection from the same source, achieve in-depth coverage of monitoring data and collection and monitoring on the distribution side and power consumption side, and improve terminal intelligence and Edge computing level. Unified access is conducive to the stability of the response of the user-side monitoring system, and the cameras can obtain timely and accurate audio and video data through sensors distributed in different directions.

 

1.2 Platform layer

       The realization of the platform layer relies on the enterprise middle station, sharing platform service capabilities, and supporting the monitoring system of the electric energy metering device. Through the interconnection of distributed control centers, the unified IoT management of ultra-large-scale sensors and monitoring systems is realized, and the construction of a unified data center for all services is deepened.

1.3 Application layer

1.3.1 Customer Service

       Optimize the allocation of power resources, stop waste, reduce power consumption, shift peaks and fill valleys, promote renewable energy power consumption, reduce pollutants and greenhouse gas emissions, and realize power saving, environmental protection, green power, and intelligence Electricity and orderly consumption.

1.3.2 Enterprise Operation

       Through the monitoring of metering devices, it can realize the application of early warning of enterprise equipment status, electricity sales and load forecast, new energy power generation power forecast, etc., improve the level of lean management, catalyze the internal technological innovation and new product development of the enterprise, and improve the quality of production products, thereby improving the economic efficiency of the enterprise.

1.3.3 Grid operation

       Through the monitoring of the metering device, the power supply quality capability of the power grid is monitored, so as to understand the possible problems and hidden dangers in the operation of the power grid.

1.3.4 Emerging business

       The construction of an electric energy metering and monitoring system based on the ubiquitous power Internet of Things has changed the traditional power supply and use relationship into a mutually trusting cooperative relationship. The specific emerging business forms include: peak and valley electricity use reminders, three-phase load adjustment suggestions, Demand side analysis, total meter set meter power balance analysis, common sense training on electricity consumption, emergency alarms, etc.
