Control system for detecting water flow in water pipe

Abstract

The invention discloses a control system for detecting a water flow in a water pipe. The control system comprises an induction pole piece, a capacitance detecting induction unit, a control processingunit, a control output unit and a power supply unit, wherein the induction pole piece is in communication connection with the control processing unit by means of the capacitance detecting induction unit, and the control processing unit is further connected with the control output unit and the power supply unit. In this way, the control system for detecting the water flow in the water pipe providedby the invention can detect variation of the water flow, and has the advantages of being simple, easy in integration and high in reliability; and the induction pole piece is not in direct contact with a detected liquid, a control loop triggers a controlled system to operate when water flows in the water pipe, thus the reliability is high, and a safer and more reliable product using experience isbrought to the user.

Description

technical field [0001] The invention relates to the field of drainage systems, in particular to a control system for detecting water flow in water pipes. Background technique [0002] At present, most of the detection and control methods using water as the medium in the market are mechanical switches and electrode-type water level measurement methods, which inevitably have their own shortcomings. The electrode type has the risk of electric leakage in the metal part, and the mechanical switch needs the buoyancy of water to realize it. Once there is a failure, there may be irreparable losses. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a control system for detecting the water flow in the water pipe, which can detect the change of the water flow, and also has the characteristics of simplicity, easy integration and high reliability. When water flows through the water pipe, the control loop triggers the controll...
