Description
Technical field
The present invention relates to a kind of water pump control method and device.
Background technology
Traditional pump control unit mode：It is the delivery port installation pressure sensor in water pump, when water tank full water state,
Float valve is closed, and pressure increases to certain value in water pipe, and pressure switch disconnects, and water pump is also stopped.This control method
In the presence of many drawbacks, pressure valve contacts in water for a long time, corrosion and it is water stain the problem of, cause the pressure valve life-span not grown, also in water
If impurity, the tightness of pressure valve can be influenceed, causes valve to damage cisco unity malfunction.Due to being pressure valve control, water
The change of pressure, such as user turn on the tap, and either water tower somewhat lacks water or pipe leakage, and pressure is also with regard to small, pressure valve
Water pump will be automatically turned on, such water pump can frequently switch on.Greatly shorten the water pump life-span.Because pressure valve connects with water for a long time
Touch, so the life-span is shorter, user needs to make professional personnel be repaired, installed and be debugged, the used time generally require 2 hours with
On.In the case of unattended, if pressure valve breaks down, or pressure valve is blocked by the impurity in water, and water pump will be always
Work, it is hot, until burning, huge hidden danger is buried to potential safety hazard.Because pressure reduces, what pump switch will be opened
Design defect, water inside water tower can be caused not update for a long time, for a long time without cycling use of water, the water inside water tower will
It is contaminated, influence with water health.
Another kind is the placement high-low water level sensor in water tank, it is necessary to is pacified with wire from water tank to water pump location
Dress, when water level is low arrives lower sensor, water pump just automatically begins to work, and water level is shut off water pump to high water level sensor,
The wiring of this control mode is cumbersome, and installation trouble is, it is necessary to electrician and water conservancy project are constructed simultaneously, and when building construction,
Will pre-buried control line, be that can not realize pre-buried, this control mode installation and its cumbersome in the finished house much bought, such as
It is even more to have no way of doing it that fruit, which repairs no building construction drawing, and dosage is considerably less at present, and the personnel of 2 people's specialties are minimum to install
Need time half a day.If level sensor breaks down, or state of cutting off the water, water pump will work always, if unattended, water
Pump will burn, power-consuming, water wasting, also bury and carry out disaster hidden-trouble.
The content of the invention
Water pump controlling party that is simple and will not being polluted to water body is debugged the technical problem to be solved in the present invention is to provide a kind of
Method and device.
To solve the above problems, the method for the technical solution adopted by the present invention is as follows：
Step 1）System obtains the electric current of current water pump normal work automatically during pump working, averages and protects after more sub-samplings
Deposit as reference value, then continue to monitor water pump curent change；
Step 2）When monitoring water pump electric current is equal to or is approximately equal to average value, water pump normal pumping is judged；
Step 3）When monitoring water pump electric current is persistently more than average value, controller will judge that water tower is in full water state, automatic to close
Water pump；
Step 4）When monitoring water pump electric current continuously less than average value, controller will judge that water pipe is in anhydrous state, automatic to close
Water pump.
Described water pump control method, it is characterised in that：Also include setting time opening water pump function, according to the need of user
Seek setting Auto On Time.
Described water pump control method, it is characterised in that：Step 3）In, when monitoring water pump electric current is persistently more than average value
When 10%, judge that water tower water is expired.
Described water pump control method, it is characterised in that：Step 1）In, more sub-sampling numbers are 5-10 times.
A kind of pump control unit, realized according to water pump control method described above, it is characterised in that：Touched including artificial
Module, automatic read module, sampling module, memory module, real-time monitoring modular, control judge module, output module are sent out, is led to
Cross the artificial trigger module triggering automatic read module and obtain the electric current of current pump working, and entered by sampling module
The more sub-samplings of row, it is averaged value and is saved in the memory module, the monitoring modular in real time continues to monitor water pump curent change,
The control judge module is used to control water pump to be turned on and off.
The advantages of water pump control method and device of the present invention, is as follows：
1st, simple installation, one-key operation debugging：After pressing artificial trigger module with hand, control system is obtaining current water pump just automatically
The average current value often to work, debugged without professional, and continue to monitor curent change and running current value is compared
Right, when water pump electric current is equal to or is approximately equal to sample mean, controller judges water pump normally upper water, when water pump electric current continues
During more than sample mean, controller will judge that water tower is in full water or in state of cutting off the water, automatic closing water pump.
2nd, will not polluted-water：Without installing any device in water tank, therefore water pollution will not be caused.
With reference to Figure of description, the present invention will be further described.
Brief description of the drawings
Fig. 1 is pump control unit circuit theory diagrams of the present invention；
Fig. 2 is pump control unit shell mechanism schematic diagram of the present invention.
Embodiment
Shown in reference picture 1-2, water pump control method of the invention, its method is as follows：
Step 1）System obtains the electric current of current water pump normal work automatically during pump working, averages and protects after more sub-samplings
Deposit as reference value, then continue to monitor water pump curent change；
Step 2）Monitoring water pump electric current is equal to or is approximately equal to（Within ± 10%）During average value, water pump normal pumping is judged；
