Description

A kind of revolution compensation arrangement

Technical field

The utility model relates to a kind of revolution compensation arrangement, specifically is meant a kind of controller for motor of rolling up and launching on curtain or the door curtain that is used to control.

Background technology

Raising along with expanding economy and people's living standard, people's consumption idea is also gradually changing, for daily living article very high requirement has been arranged also, curtain for example, design for curtain now generally is divided into two kinds, a kind of is that manual mode is carried out folding and unfolding control, a kind of is to adopt remote controller in automatically controlled mode curtain to be carried out folding and unfolding control, because curtain more and more its weight of ambassador also increases thereupon, as carry out very inconvenience of roller shutter operation with manual mode, therefore automatically controlled mode is more and more general.But still there are some problems in existing Electric controlled window curtain, if curtain has certain weight more greatly, when making progress roller shutter, the power motor rotation direction is opposite with curtain weight, makes on the curtain volume speed slow, otherwise when roller shutter launches downwards, the revolution direction is identical with curtain weight direction, development rate is very fast, and the operator is done not feel like oneself, and excessive velocities is easy to generate noise and damages curtain mechanism when launching curtain.

The utility model content

The problem that the utility model need solve provides a kind of curtain controller for motor, it is overcome because volume and the inconsistent problem of speed when launching on the curtain that causes of controlled curtain action of gravity.

According to the above problem that needs solution, the utility model is taked following technical scheme: a kind of revolution compensation arrangement is provided, comprise motor and the drive unit that is connected with motor, described drive unit is made up of microcontroller, intermediate circuit, reversing switch and rest switch.Described microcontroller and intermediate circuit and rest switch, reversing switch all are connected, and the intermediate circuit output is connected with reversing switch, and reversing switch and rest switch output all are connected with the motor two ends.Described reversing switch adopts any in transistor or the relay; Described rest switch adopts relay.

The solution principle of the utility model scheme is: by the driving device controls revolution, when motor just changes, establish this moment for rolling up direction on the curtain, drive unit is omnidistance the driving, and motor is rotated at full speed; Be the downward expansion direction of curtain when motor reverses, drive unit then adopts intermittent type of drive, counter-rotating with stagnate that the motor counter-rotating is the deceleration rotary state under the conversion of action high speed, by this in and the downward speed that produces of curtain self gravitation.

Embodiment

For the ease of it will be appreciated by those skilled in the art that existing accompanying drawing in conjunction with the embodiments is described in further detail the utility model.

As Fig. 1,2, the utility model comprises motor 10 and the drive unit 20 that is connected with motor, drive unit 20 comprises microcontroller 21, intermediate circuit 22, reversing switch 23 and rest switch 24 in the present embodiment, and motor 10 is connected reversing switch and rest switch output.

In an embodiment:

Intermediate circuit adopts transistor Q1, Q2 connected in series.Described Q1 one end is connected with positive source, and also as first output of intermediate circuit, the Q1 other end is connected with Q2 one end this end, and this end is also as second output of intermediate circuit; Q2 other end ground connection; Q1, Q2 the 3rd end are connected with microcontroller B, A two contacts respectively as control end.

Reversing switch adopts relay R Y1, and the intermediate contact RY1-a of its first group of contact connects first output of intermediate circuit, and long closed contact ON opens contact NC with length and is connected the motor two ends respectively; The intermediate contact RY1-b of its second group of contact connects second output of intermediate circuit, and length is opened contact NC and is connected the motor two ends respectively with long closed contact ON.

Rest switch adopts relay R Y2, and its control coil two ends connect positive source V+ and microcontroller COM pin contact respectively, and contact is connected the motor two ends respectively with long closed contact NC in the middle of it.

Also be provided with in the described drive unit be used to receive the remote controller control signal and infrared receiving circuit, this device can adopt remote controller control.

The course of work was when described motor 10 was controlled forward rotation by drive unit 20: after microcontroller 21 receives the just commentaries on classics signal of remote controller, move by COM contact control relay RY2, relay R Y2 intermediate contact switches to the long contact ON end of opening, microcontroller makes in the intermediate circuit 22 transistor Q1 by, Q2 conducting by B, A two contacts then, and other controls two groups of contacts of reversing switch 23 repeat circuit RY1 and switches to the NC end.At this moment, positive source is the motor power supply through the intermediate contact RY1-a of first group of contact of relay R Y1, the long contact NC that opens, and open contact NC, intermediate contact RY1-b with the length of second group of contact of relay R Y1 and flow through transistor Q2 to ground, form current supply circuit, the CD-ROM drive motor forward rotation is finished scrolling work on the curtain.

The course of work was when described motor 10 was controlled backward rotation by drive unit 20: after microcontroller 21 receives the inverting signal of remote controller, move by COM contact control relay RY2, relay R Y2 intermediate contact switches to the long ON end of opening, reversing switch 23 repeat circuit RY1 contacts are motionless, be connected in the ON end, microcontroller makes transistor Q1 in the intermediate circuit 22, Q2 alternate conduction, ends by B, A two contacts then.

In the whole Umklapp process, transistor Q1, Q2 conducting simultaneously or end, and the ON time of transistor Q1 will be less than the ON time of transistor Q2.When Q1 ends the Q2 conducting, positive source is through first group of contact R Y1-a, ON end of relay R Y1, by illustrated motor lower end pin enter, the upper end pin flows out and to form reverse current, and reflux in RY1 second group of contact ON, RY1-b, after transistor Q2 ground connection, at this moment, the motor backward rotation, curtain launches downwards.When transistor Q1 conducting, when Q2 ends, transistor Q2 cuts off the motor earth terminal, and reverse current can not circulate, and motor and curtain are in halted state.

Transistor Q1, Q2 are subjected to microprocessor controls high speed alternate conduction, end, and make motor reversing and stopping high-speed transitions under the two states, cause its counter-rotating to be deceleration regime, and curtain also slowly launches with motor speed.

It is that relay R Y2 switches to the NC end that microcontroller COM contact output control signal makes rest switch, no matter Q1, Q2 conducting or end, and RY1 is in all non-transformer is to the current path on ground in which kind of state motor, and motor is in stable halted state.

The utility model controller for motor can be applicable to curtain or door curtain place; and available remote controller carries out Long-distance Control; control by means of motor drive; governor motor forward and backward speed; overcome curtain or door curtain because the acceleration that gravity produces; make on curtain or the door curtain volume consistent, well protect curtain or door curtain mechanism with development rate.

Need to prove; foregoing circuit only is the utility model preferred embodiment; protection range of the present utility model is not limited thereto, and not breaking away from any impartial variation of under the utility model design prerequisite circuit being done and modification, all belongs to protection range of the present utility model.
