Water-electricity-coal gas integrated charging control system

Abstract

The invention discloses a water-electricity-coal gas integrated charging control system and relates to a charging control system. One ends of a first water metering controller, a second water metering controller, an electricity metering controller and a coal gas metering controller are provided with a tap water inlet, a centrally supplied hot water inlet, a 220V alternating-current inlet/outlet and a liquefied gas inlet, respectively; the other ends of the first water metering controller, the second water metering controller, the electricity metering controller and the coal gas metering controller are connected with an IC card water-electricity-coal gas controller through an RS485 communication bus; the IC card water-electricity-coal gas controller is connected with one end of a converter through the RS485 communication bus; the other end of the converter is connected with a background recharge managing software system. According to the water-electricity-coal gas integrated charging control system, the charging of cold water, hot water, electricity and coal gas is managed by one card, and the charging of water, electricity and coal gas are performed according to metering, so that the waste phenomenon caused by charging according to the number of people or indistinctly charging according to family in the traditional house renting industry is avoided, the safety is improved and convenience is brought to the life of people.

Description

technical field [0001] The invention relates to a charging control system, in particular to a water, electricity and coal integrated charging control system. Background technique [0002] The existing metering and billing for water, electricity, and gas are mainly traditional water and electricity meters and prepaid meters. Due to the use of prepaid methods and separate management through multiple cards, it has caused rental houses, public rental houses, apartments, etc. In the case of large population mobility, the charges are not timely, the manual management is cumbersome, the rent is not collected in time, and the water, electricity and coal are not turned off when the house is empty, which is not safe. It is very inconvenient to use. In order to solve the above problems, a water, electricity and coal integration is designed. A charge control system is still necessary. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the ...
