Abstract

The invention relates to an IC card real time electricity-charge deducting control system of an air conditioner, which comprises an IC card management module, an IC card, an IC card controller and an air-conditioner controller which are connected sequentially. The air-conditioner controller comprises an air-conditioner master control singlechip, an electric quantity detection unit, a first communication interface and an air-conditioner routine control unit, wherein, the electric quantity detection unit, the first communication interface and the air-conditioner routine control unit are connected with the air-conditioner master control singlechip respectively; the IC card controller comprises a second communication interface, an electricity-charge deducting control singlechip, a first IC card read-write interface and a first IC card read-write device which are connected sequentially. The IC card real time electricity-charge deducting control system controls the air-conditioner electricity-charge consumption through the IC card real time charging and deducting way, realizes the intelligentized multi-user power utilization, and has the characteristics of intelligentization and easy realization.

Description

technical field [0001] This patent relates to the field of air-conditioning control, in particular to an air-conditioning IC card real-time deduction electricity charge control system. technical background [0002] At present, in the field of prepaid air conditioners, the solution of air conditioners plus prepaid electric meters is generally adopted. Prepaid energy meters are also called quantitative energy meters and IC card energy meters. In addition to the metering functions of ordinary energy meters, in particular, users buy electricity first, and then use electricity after buying electricity. After the user does not continue to buy electricity, then Automatically cut off the power to stop the power supply. There are two methods for pre-storing electricity charges, one is a code type, and the other is a write-card type. The principle of the code method is that the management system combines user information and electricity purchase information to generate a set of encr...
