Real-time control method of IC card electric energy meter in public place

Abstract

A real-time control method of an IC card electric energy meter in a public place comprises an IC card module, an electric energy meter single-chip microcomputer control module, a relay and a user load module, wherein the electricity utilization condition of the public place is controlled in real time. According to a control system, on the basis that IC card control is used in the public place, the functions for judging the state of an IC card in the meter and calculating the electric quantity in the meter in real time are added, if the IC card exists in the electric energy meter, a power supply system is connected, and electric devices run; if the IC card is pulled out of the meter, a power supply is cut off, and the devices stop running; particularly after the public place is closed, the phenomenon that low power consumption can still be generated under the power-on condition is avoided for all the electric devices which do not work; electricity utilization efficiency is improved, the energy conservation and consumption reduction purpose is achieved, and accidents such as a fire disaster caused when there are not enough personnel for timely watch or wires age in some public places are effectively prevented.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to a real-time control method for IC card electric energy meters in public places. Background technique [0002] The use of IC card electric energy meters to control electricity consumption and electricity costs has been widely adopted by users and management units. At present, the method and steps of ordinary IC card electric energy meter to control electricity consumption and cost are as follows: [0003] IC card activation, write information S01→purchase electricity S02→insert card to read meter S03→electric energy meter read card information, judge in two situations: [0004] (1) The electric energy meter recognizes the card, then reads the card information, and pulls out the IC card after receiving the electricity S04→the electric meter judges the electricity, which can be divided into the following two situations: [0005] ① If the remaining power is greater t...

AI Technical Summary

Problems solved by technology

The use of IC cards can be divided into two situations. One situation is that the IC card is always inserted into the energy meter, and the other situation is that the power information purchased in the IC card is charged into the electricity meter at one time. The biggest disadvantages of these two usage situations When the user does not need electricity, some electrical equipment will still consume part of the electric energy, and the control cannot achieve real-time performance, and cannot meet the purpose of saving energy and reducing consumption in many public places, especially not conducive to improving the effective utilization of electrical equipment
