Prepayment management system and edge computing communication terminal

The invention provides a prepayment management system and an edge computing communication terminal. An edge computing communication terminal is arranged between an electric meter and a cloud background server; the edge computing communication terminal establishes a virtual ammeter data computing storage module with a unique number for each accessed ammeter; a cloud background server is replaced tocarry out degree reading and electric charge calculation on the electric meter; a common electric meter without a prepayment function can achieve the prepayment function, electric charge and prepayment balance calculation can be completed more quickly, electricity control can be conducted more quickly and timely, and it is guaranteed that important data and commands such as electricity price information, recharging data and an electricity control instruction are encrypted through an algorithm and are safely communicated through a wide area network. The problem of resource limitation caused bythe fact that a tradition
