Description

technical field [0001] The invention relates to the field of electricity sales, in particular to a fee control device, a prepaid electricity sales system, an electricity sales system and a method. Background technique [0002] In recent years, with the development of smart electricity technology, the convenience of purchasing electricity has attracted more and more attention from consumers, and the shortcomings of traditional electricity purchasing methods have also been increasingly exposed. The traditional way of purchasing electricity is: purchasing electricity with a card, local fee control, and plugging in a card for power transmission, that is, each power user is equipped with an electric card, and the first time you purchase electricity, you need to go to the power business hall to open the card; each time the user purchases electricity When purchasing electricity, the card must be purchased, and the electricity data of each electricity purchase is written into the el...

AI Technical Summary

Problems solved by technology

[0004] However, there are serious deficiencies in the traditional electricity purchase method of the above-mentioned utility model, and the electricity purchase process is relatively cumbersome. After each electricity purchase, the user must insert the electric card into the electric meter to input the purchased electric power into the electric meter; since the electric card and the electric meter are often in direct contact, the two The contact surface is relatively easy to cause wear and tear, which reduces the service life of the electric card and the electric meter; because the traditional electric meter must use the electric card medium for power transmission, the traditional electric meter must have a card slot, resulting in a relatively high cost of the traditional electric meter
