Electric energy meter transaction terminal based on DCEP local Internet of Things payment

Abstract

The invention belongs to the field of power equipment, and particularly relates to an electric energy meter transaction terminal based on DCEP local Internet of Things payment. The terminal comprises a DCEP control module and a DCEP payment module. The DCEP control module comprises a main control unit, a first communication unit, a coin string interface, a DCEP SAM unit and an interaction unit. The first communication unit is used for establishing communication between the main control unit and the electric energy meter. The coin string interface is a communication interface between the DCEP control module and a DCEP payment module. And the DCEPSAM unit is a module for security authorization and hardware encryption. The DCEP payment module comprises an electronic wallet, a wallet management unit and a second communication unit. And the wallet management unit is used for managing the DCEP balance in the electronic wallet. And the DCEP payment module communicates with a background data center of the bank through the second communication unit. The problems that an existing electric power system cannot carry out local settlement on the electric charge, and a traditional electric charge payment mode is time-consuming, labor-consuming, delayed and prone to being affected by the network connection state are solved.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to an electric energy meter transaction terminal based on DCEP local Internet of Things payment. Background technique [0002] As a metering terminal for customers' electricity consumption, smart energy meters are an indispensable and important part of data collection in smart grids (especially smart distribution networks), and are the basis for fair and open power transactions. However, conventional smart energy meters usually only have the functions of electricity metering and electricity bill calculation, and cannot realize the function of payment settlement. [0003] At this stage, if resident users need to pay for their electricity accounts, they need to go to the local offline State Grid business hall or other outlets that pay electricity bills to pay. These problems may affect the normal electricity consumption of users, causing users to underestimate the remain...
