Title:
CONTROL SYSTEM FOR DETECTING WATER FLOW IN WATER PIPE
Document Type and Number:
WIPO Patent Application WO/2020/258440
Kind Code:
A1
Abstract:
A control system for detecting a water flow in a water pipe, the system comprising an inductive pole piece, a capacitance detection induction unit, a control processing unit, a control output unit and a power supply unit, wherein the inductive pole piece is in communication connection with the control processing unit by means of the capacitance detection induction unit, and the control processing unit is also connected to the control output unit and the power supply unit. By means of the method above, the control system for detecting a water flow in a water pipe is able to detect a change in the water flow, and also has the characteristics of simplicity, ease of integration and high reliability; the inductive pole piece is not in direct contact with detected liquid; and when there is a water flow flowing through the water pipe, a control loop triggers the operation of the control system, achieving high reliable security, and bringing more secure and reliable product usage experience to users.
