Abstract
The invention relates to a control method and a controller for a water pump, in particular to an automatic control method and a controller for the water pump by using a Hall flow sensor. The Hall flow sensor is arranged on a cold water or hot water supply pipeline, and is used for detecting the presence or absence of water. The automatic control method is simple, and by the automatic control method, when a water point is turned off, the water pump is automatically stopped, so the best energy-saving effect is achieved. The method has the advantages of sensitive response, simple maintenance and low cost.
Description
Technical field
The present invention relates to a kind of water pump controlling method and controller thereof, be specially the water pump autocontrol method and the controller thereof that utilize the Hall flow transducer.
Technical background
In the daily in the market small-sized cooling water heating system, the automatic control of water pump there is following several method: water switch, but this type switch cost is high slightly, and price is expensive partially; Second kind is pressure switch, and pressure switch has a maximum shortcoming troublesome poeration, breakout pressure with stop the bad control of pressure, or water pump can frequent starting, or water pump does not start, and is easy to burn out water pump, and is not energy-conservation; Also having a kind of is the conversion method control of pump, and adopts pressure sensor is controlled water pump and loine pressure automatically, costs an arm and a leg, and is impractical in small watersupply system.
Summary of the invention
The object of the invention is to provide that a kind of cost is low, control simple water pump autocontrol method and controller thereof, overcomes the deficiencies of above several kinds of controlling methods commonly used, and concrete technological scheme is:
The Hall flow transducer is installed on cold water or the hot water feeding pipe road; Utilize the Hall flow transducer to detect and have or not the water yield, when water flow through Hall flow transducer magnet rotor assembly, magnet rotor rotated; And rotating speed is along with the linear variation of flow; Hall element in the Hall flow transducer is exported corresponding pulse signal and is transported to MCU single-chip microcomputer master controller unit, and MCU single-chip microcomputer master controller unit sends the power supply of instruction feed water pump to relay, and water pump is opened; When with water spot during without water, no flow in the pipeline, the Hall element pulse-free signal is given MCU single-chip microcomputer master controller unit, and MCU single-chip microcomputer master controller unit does not have instruction to output control unit, output control unit disconnection pump power, water pump quits work.
This water pump control method utilization be the water pump automatic controller, this water pump automatic controller comprises Hall flow transducer and control module; The Hall flow transducer is responsible for gathering flux signal, the output pulse; Control module is responsible for handling the various signals of gathering, the start-stop action of instruction water pump.
The control module of water pump automatic controller comprises single-chip microcomputer master controller unit and output control unit; Control module also comprises the LCD display unit.
Except automatic control to water pump; The water pump automatic controller can also be provided with flow size to the pipeline medium, flow summation, heat energy and use data, pipeline medium temperature feedback, pressure feedback etc. to analyze and compare; The working state of monitoring of water pump automatic controller and judgement pipeline; Export various control commands, and carry out corresponding action and handle.
This autocontrol method is simple, closes with water spot one, and water pump just stops automatically, reaches optimum energy-saving effect.This method has the reflection sensitivity, is easy to safeguard, and is with low cost.

Fig. 1 is a water pump automatic controller structural representation of the present invention;
Fig. 2 is that the present invention uses schematic representation;
Fig. 3 is an application implementation illustration intention of the present invention;
Fig. 4 is an application implementation illustration intention of the present invention.
Embodiment
Accompanying drawings embodiment of the present invention, as shown in Figure 1, it is Hall flow transducer 1 and control module 2 that the water pump automatic controller is made up of two-part; Hall flow transducer 1 is responsible for gathering flux signal, the output pulse; Control module 2 is responsible for handling the various signals of gathering, the start-stop action of instruction water pump.
The control module of water pump automatic controller 1 as shown in Figure 2 comprises MCU single-chip microcomputer master controller unit and output control unit; Also comprise the LCD display unit; Pipeline medium temperature feedback that MCU single-chip microcomputer master controller unit is also integrated simultaneously; MCU single-chip microcomputer master controller unit obtains temperature information through temperature collecting cell, and carries out signal processing and send instruction.
The Hall flow transducer normally is used for detecting the flow size, and the present invention detects with the Hall flow transducer to have or not water flow, utilizes the Hall effect of Hall element to measure the Physics of Magnetism amount.Positive pole at Hall element seals in load resistance, and the VDC of logical simultaneously upward 5V also makes current direction and the magnetic direction quadrature.When water promotes the rotation of Hall flow transducer magnet rotor through the turbine switch housing, produce the rotating magnetic field of different magnetic poles, cutting magnetic induction is answered line, produces the height impulse level.The Hall flow transducer is installed on cold water or the hot water feeding pipe road; Utilize the Hall flow transducer to detect and have or not the water yield, when water flow through Hall flow transducer magnet rotor assembly, magnet rotor rotated; And rotating speed is along with the linear variation of flow; Hall element in the Hall flow transducer is exported corresponding pulse signal and is transported to MCU single-chip microcomputer master controller unit, and MCU single-chip microcomputer master controller unit sends the power supply of instruction feed water pump to relay, and water pump is opened; When with water spot during without water, no flow in the pipeline, the Hall element pulse-free signal is given MCU single-chip microcomputer master controller unit, and MCU single-chip microcomputer master controller unit does not have instruction to output control unit, output control unit disconnection pump power, water pump quits work.
So reach the automatic control purpose of water pump.
As shown in Figure 3, to the little occasion of water consumption, can directly be serially connected in the water pump automatic controller in the pipeline.
As shown in Figure 4, if the bigger occasion of water consumption then can be connected bypass line to the water pump automatic controller and connect.In case with water end (W.E.) people's water is arranged, the magnet rotor assembly of the Hall flow transducer in the water pump automatic controller of bypass can perceive water and flow through, and the water pump automatic controller is the start-stop of ability control of pump equally.
