Method and system for prompt payment energy management

Abstract

The invention relates to a time limited paid power consumption management method and a system thereof, which consists of four main parts of a novel watt-hour meter, a power consumption information card, a writing card device and computer management software. The invention uses a time limited paid power consumption management mode, therefore, the novel watt-hour meter can read in and store a terminated date on the power consumption information card into the watt-hour meter, then comparison is made with the current time and power supply is cut off if the terminated date arrives, a user goes to a power supply management department to pay power fee of the prior period, the writing card device and the computer management software are used by the power supply management department for writing a new terminated date on the power consumption information card that is taken back by the user and inserted again, then a card reader of the novel watt-hour meter reads and stores the new terminated date, an electric circuit is opened and power is supplied to the user if the current time does not exceed the terminated date. Electric quantity can be directly read from a degree display screen of the novel watt-hour meter and power consumption quantity of the watt-hour meter on a RS485 interface circuit can be read by using DL / T645 Multi-function Watt-hour Meter Communication Protocol, thereby meeting the requirement of remote meter reading.

Description

technical field [0001] The present invention relates to a method and system for time-limited payment management of electricity consumption, in particular to an electricity consumption management system consisting of four parts: a new type of electricity meter, an electricity consumption information card, a card writing device and computer management software in the electricity consumption management industry. methods and systems. Background technique [0002] At present, the method of charging for electricity consumption is generally to use electricity first and then charge. Later, the power supply departments in some places used prepaid ammeters. This way of using electricity is to purchase electricity from the power supply department with a contact IC power card, and then store the power of the contact IC power card in the prepaid ammeter, and then The prepaid meter gradually reduces the pre-stored power according to the used power, and when the pre-stored power is zero, ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems existing in the existing charging methods, the purpose of the present invention is to overcome the three major contradictions of electricity fee collection in the charging method after using electricity and the three major contradictions in the pre-paid charging method, adopt new technical routes and technical means, and then provide an instant It can solve the difficulty of charging and provide users with a reasonable, reasonable and legal way of using electricity
