Water purification device, flow billing system and method for water purification device

Abstract

The invention discloses a water purifier and a flow billing system and method for the water purifier. The flow billing method for the water purifier comprises: a flow meter is arranged behind an RO (Reverse Osmosis) membrane, meters water flow flows through the pure water side of the RO membrane, subjects the flow to being generated into digital signals, and transmits the digital signals to a processor of the water purifier; the processor calculates and stores corresponding fees according to single-time flow information, and simultaneously sends calculated results to a remote server through a wireless communication module; or the processor utilizes the wireless communication module to directly send flow data metered by the flow meter to the server, and the server calculates the corresponding fees according to the flow data; and the server inputs account data of corresponding users according to fee information which is sent by every water purifier or calculated by the server. The flow accounting method for the water purifier can achieve the effect of calculating water fee according to the flow; and solves the problems of large reconstruction investment, large engineering difficulty, high use costs, less users with long-term use intention and many uncertain factors of water quality in a direct drinking water centralized water supply scheme.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, and relates to a water purification device, in particular to a flow billing system of a large-scale multi-user water purification device and a user management method from decentralized billing to centralized management to decentralized payment; at the same time, the present invention The invention also relates to a flow accounting method of the water purification device. Background technique [0002] Water is an indispensable natural resource for human development and the material basis for the survival of human beings and all living things. Today, the water source crisis caused by insufficient water resources and pollution has become a major issue in the development of the country and people's livelihood, a complex problem facing the economy and technology, and a major constraint on social and economic development. In the case of increasingly scarce water resources, the realit...

AI Technical Summary

Problems solved by technology

[0004]Currently, the concentrated direct drinking water scheme in the domestic community has large investment, difficult engineering transformation, high construction and operation cost, high use and promotion cost, and high user cost after putting into use. There are not many users willing to use it for a long time in a community, which leads to high cost sharing. In particular, problems such as water quality deterioration at the dead end of the pipeline without users causing major safety hazards make it difficult to promote direct drinking solutions in many communities
