Abstract
The invention relates to a brush motor control circuit of an ecological house. The circuit is formed by connecting a signal input port, two comparators, a triode, a motor and nine resistors. The brush motor control circuit has the advantages that: double power supplies are unnecessary; and a supply circuit is simplified.
Description
Technical field
The present invention relates to circuit field, particularly a kind of brush motor control circuit of ecological room.
Background technology
Ecological room design of Controller theory is that imitation meets human body more a good life, rest environment arise at the historic moment technology-imitation natural ecological environments such as application message electronics, the effect that can play beauty treatment, skin care, takes care of health.Be integrated into a control system with these more existing practical techniques and realize that whole system is divided three modules: air-conditioning control module, central controll block, human-computer interaction module, realize mutually by communication modes between three control modules between the information transmission.
But in the prior art, the brush motor control circuit system in ecological room is imperfection also.
Summary of the invention
The present invention provides a kind of brush motor control circuit of simple and effective ecological room in order to overcome the deficiency of above technology.
The present invention realizes by following measure:
A kind of brush motor control circuit of ecological room is formed by connecting by a signal input port (PWM), two comparators (IC1A, IC1B), a triode Q, motor D J, nine resistance (R1-R9),
Be connected on the base stage of triode Q1 behind the signal input port PWM series resistance R1, the series circuit of the base stage of triode Q1 and emitter span connecting resistance R2 and R3, the collector electrode series electric motor DJ of triode Q1 is connected to operating voltage VDD, be connected on the negative pole of comparator IC1A behind the base series resistor R4 of triode Q1, the positive pole of comparator IC1A and No. 1 port span connecting resistance R9, No. 1 port and No. 2 port span connecting resistance R10 of comparator IC1A, number port of comparator IC1A meets supply power voltage VSS, the negative pole of comparator IC1A and No. 3 port span connecting resistance R8, No. 3 port ground connection of comparator IC1A
