Description
Technical field
It the utility model is related to a kind of direct current fountain pump.
Background technology
At present, the electric current, voltage or duty cycle of pump motor are controlled by control circuit needs so as to reach to use
The water pump asked worldwide still belongs to blank.And in actual industrial circle application, the control for pump technology parameter
What system was controlled often by the technical characteristic and various complicated pipe valves of pump itself.Due to the office of its control method
It is sex-limited, so it is difficult to being carried out to the working status of water pump in time, conveniently and fine control.So it is badly in need of a kind of direct current spray
Spring pumps, and timely, convenient and fine control cannot be carried out to its working status to solve traditional water pump.
The content of the invention
The technical problems to be solved in the utility model is to solve traditional water pump to carry out in time, conveniently its working status
And fine control.
Above-mentioned technical problem is solved, the utility model provides a kind of direct current fountain pump, including water pump, it further includes water pump
Driving, water pump driving include DMX control units and PWM control units, the water pump drive be additionally provided with power input line,
DMX signal input lines, DMX output lines, the DMX control units connect the PWM control units, and the PWM controls are single
Member connects the motor of the water pump；
The PWM control units are used to be modulated signal waveform；
The modulus that the DMX control units correspond to the motor by passage carries out assignment, is controlled by adjusting its assignment
Make the modulus of the water pump.The modulus generally comprises the electric current, voltage, duty cycle of motor.
Further, the water pump is threephase motor water pump.
Further, the DMX control units are DMX512 controllers.
Further, the DMX control units are circumscribed with control platform.
The beneficial effects of the utility model：
1. the voltage, electric current, duty cycle of water pump are controlled by DMX control units accomplish it is timely, conveniently, finely,
And then the working status of motor is controlled and realizes its requirement.
2. tradition is changed to be controlled by circuit, significantly to the design regulative mode on water pump structure and pipeline
Reduce design difficulty and cost.
Significantly reduce 3. global design takes up space, limited from place, suitable for every field.
Brief description of the drawings
Fig. 1 is the circuit connecting relation schematic diagram of the utility model；
Embodiment：
Following embodiments are only for clear this example of utility model, and not to the embodiment party of the utility model
The restriction of formula.For those of ordinary skill in the field, it is different that other can also be made on the basis of the following description
The change or variation of form, and these belong to the spiritual obvious changes or variations drawn of the utility model still in this
Among the protection domain of utility model.
As shown in Figure 1, a kind of direct current fountain pump, including water pump 1, it further includes water pump driving 2,2 bag of water pump driving
Include DMX control units 3 and PWM control units 4, the water pump driving 2 be additionally provided with power input line 5 (power supply),
DMX signal input lines 6 (DMX IN), DMX output lines 7 (DMX OUT), the DMX control units 3 connect the PWM controls
Unit 4 processed, the PWM control units 4 connect the motor 8 of the water pump 1；
The PWM control units 4 are used to be modulated signal waveform；
The DMX control units 3 by passage correspond to the motor 8 modulus carry out assignment, by adjust its assignment come
Control the modulus of the water pump 1.
Each control parameter (electric current, voltage, duty cycle) modulus is converted into percentage 100%, then averagely corresponds to institute
State DMX control units 0-255 and carry out assignment.Corresponding by adjusting the control DMX control units 0-255 inputs numerical value, from
And its specific modulus will be controlled, reach control effect timely, conveniently, fine.The modulus generally comprises the electric current of motor, electricity
Pressure, duty cycle.
The water pump is threephase motor water pump.
The DMX control units are DMX512 controllers.
The connection of the DMX control units 3 control platform, can any one external control platform.
Its basic principle and application method：
Direct current fountain pumps, and as its name suggests, is the straightway pump for fountain, can also expand to other straightway pumps.By right
It carries out frequency conversion, makes it in the power of the water-saving pump of free position downward, water, water speed, switch, frequency.
First, it is translated into by controlling platform adjusting numerical value by the passage assignment of the DMX control units to the electricity
The control signal of machine 8, signal be modulated by the PWM control units to be formed after regular signal to the pump motor into
Row control, is usually assigned a value of percentage 0-100% by electric current, voltage and duty cycle etc. and goes the average corresponding DMX control units
The assignment of passage 0-225.And then its corresponding exterior specific modulus (such as voltage, electric current, duty cycle) is realized to the motor 8
Control, and then control the power of water pump, water, even water speed, the switch of motor and other modulus.
The power input line 5 (power supply) is used to power, DMX signal input lines 6 (DMX IN), DMX signals
Output line 7 (DMX OUT) is used for the assignment and coding of the DMX control units.
