Charge-by-household system of air conditioners

Abstract

Embodiments of the present invention disclose a charge-by-household system of air conditioners. The charge-by-household system comprises at least one air-conditioning unit comprising air-conditioning external units and at least one air-conditioning internal unit; an intelligent electric meter used for metering power consumption information of each air-conditioning external unit; and a charging gateway used for calculating electric charge of each air-conditioning external unit according to obtained operation information of the air-conditioning external units and the air-conditioning internal units and the power consumption information of each air-conditioning external unit. According to the charge-by-household system of the air conditioners, the power consumption information of a plurality of air-conditioning external units is metered by using one intelligent electric meter, so that the size of the charge-by-household system is reduced; the intelligent electric meter is directly and electrically connected with the charging gateway, so that bus wiring is simplified, and signal interference among a plurality of buses is prevented; and communication stability and reliability between the charging gateway and the intelligent electric meter are improved, communication fault rates are reduced, and installation cost is correspondingly reduced.

Description

technical field [0001] The embodiment of the present invention relates to electric energy billing technology, in particular to a household billing system for air conditioners. Background technique [0002] The central air-conditioning billing system is actually a billing system technology developed on the basis of water, electricity, and gas to measure electric energy. [0003] like figure 1 Shown is an existing central air-conditioning household billing system. As shown in the figure, the three-phase power supply supplies power to the air-conditioning external unit. Each air-conditioning external unit is equipped with a single-user electric meter and connected electrically. The single-user electric meter is only used to calculate the power consumption information of the corresponding air-conditioning external unit. Each single-user The electricity meters are also connected to the billing gateway through the bus, and the billing gateway is electrically connected to each ai...
