Self-harvesting water energy power supply water-saving system for restroom and intelligent monitoring method thereof

Abstract

The present invention discloses a self-harvesting water energy power supply water-saving system for a restroom and an intelligent monitoring method thereof. The system comprises a self-generating electric module, an electric power storage module and a control module. The self-generating electric module comprises a hydraulic generator and a voltage stabilization module; the electric power storage module comprises a lithium ion battery, a battery protection circuit and a voltage reduction module; and the control module comprises a controller, an infrared detection module and an execution module.The method comprises the steps of: 1, obtaining signals of the infrared detection module and a voltage of the lithium ion battery; 2, determining whether the voltage of the lithium ion battery is smaller than a voltage threshold value; 3, charging the lithium ion battery; 4, determining whether there is a user using a restroom or not; and 5, opening a solenoid valve for drainage, and performing charging of the lithium ion battery. The self-harvesting water energy power supply water-saving system for the restroom and the intelligent monitoring method thereof are low in cost and convenient to install, can select different closure time of the solenoid valve according to the different usage time of the restroom by the users to achieve different flushing time of the restroom and save water resources, and the generation module is a chargeable lithium ion battery to effectively save electric energy.

Description

technical field [0001] The invention belongs to the technical field of water-saving systems for toilets, and in particular relates to a self-captured water energy-powered water-saving system for toilets and an intelligent measurement and control method thereof. Background technique [0002] As we all know, water is the source of life and an indispensable precious resource for the national economy. However, due to various reasons, the phenomenon of wasting water resources is not uncommon, and the problem of water conservation has become the focus of attention all over the world. Taking toilets as an example, there are often phenomena of not flushing or long running water after defecating, causing serious environmental pollution and waste of water resources. In addition, most toilets still use manual flushing devices, which has health problems such as bacterial cross-infection. For the problems referred to above, many research institutes at home and abroad have developed toi...

AI Technical Summary

Problems solved by technology

At present, automatic flushing devices have been installed in newly-built toilets, but the power supply modules of these devices generally adopt two ways of laying dedicated line power supply or dry battery power supply, which has the problem of saving water and not saving electricity

Especially in the renovation project of old toilets, due to the limitations of the power supply mode and structure of the existing toilet automatic flushing device, the power supply module in the toilet automatic flushing device must be cut and installed, which is very inconvenient, time-consuming and laborious, and economical. And other issues
