Prepayment management system and edge computing communication terminal

Abstract

The present invention provides a prepayment management system and an edge computing communication terminal. By setting the edge computing communication terminal between the electric meter and the cloud background server, the edge computing communication terminal establishes virtual electric meter data with a unique number for each connected electric meter. The calculation and storage module replaces the cloud background server to read the electricity meter and calculate the electricity fee, so that the ordinary electricity meter without the prepayment function can realize the prepayment function, and can complete the calculation of the electricity fee and the prepaid balance faster, and control the electricity more quickly and timely , to ensure that important data and commands such as electricity price information, recharge data, and electricity control instructions are encrypted by algorithms and communicated securely through the wide area network; to solve the resource constraints caused by the expansion of servers and network communications in traditional background prepaid systems due to the increase in the number of meters, and to expand access to meters Quantity; the use of the prepaid function of the meter user is not affected by the failure of the cloud background server and the failure of the communication network, the system reliability is high, and the data communication is safe.

Description

technical field [0001] The invention relates to the technical field of power supply charge management, in particular to a prepayment management system and an edge computing communication terminal. Background technique [0002] The prepayment mode of electricity charging has been more and more popularized and applied. The prepaid mode generally requires the use of a special prepaid meter. The customer first recharges the meter, and the meter automatically bills and deducts the pre-stored amount of electricity charges according to the electricity consumption situation. However, at present, many ordinary smart meters that have been installed do not have the prepayment function. If the prepayment charging mode is to be promoted, all of them need to be replaced with smart meters with the prepayment function. The scale and cost of meter replacement are too large to be implemented in large quantities. [0003] For this reason, people have proposed another implementation method of ...
