Detailed description of the invention
In order to be more likely to be clearly understood the content of the utility model, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model, in which:
Fig. 1 is the structural frames schematic diagram of the utility model.
Specific embodiment
(embodiment 1)
Fig. 1 shows a kind of specific embodiment of the utility model, and wherein Fig. 1 is that the structural frames of the utility model are illustrated
Figure.
See Fig. 1, it is a kind of can stroke positioning the driving of DALI electrically driven curtain, including the driver being connected with electrically driven curtain 1
2, the curtain motor control circuit that the driver 2 includes processor of single chip computer 21, is connected with the processor of single chip computer 21
22 and the DALI signal transmitting and receiving interface circuit 23 that is connected with the processor of single chip computer 21, the curtain motor control circuit 22
It is connected on electrically driven curtain 1 curtain motor, the DALI signal transmitting and receiving interface circuit 23 is connected with DALI signal bus 3
It connects, further includes the external key control circuit 24 being connected with processor of single chip computer 21.
The DALI signal bus 3 is connected with control PC4.
DALI signal transmitting and receiving interface circuit: it realizes the reception of DALI signal on system bus and is sent to single-chip microcontroller, simultaneously
The signal that single-chip microcontroller can be sent is sent on system bus.
Single-chip microcontroller processing circuit: configuration and control instruction on processing DALI system bus, stroke parameter processing and curtain
Motor range control management.
Curtain motor control circuit: connection curtain motor uplink (unlatching) line and downlink (closing) line, and control curtain electricity
Machine.
External control key control circuit: realizing the extension access of external key panel, and user can manually control curtain motor.
By control PC, it can be achieved that the online programming of DALI electrically driven curtain driving and configuration, the parameter declaration of configuration is such as
Under:
It closes (downlink) time Tm: closing the total time that (downlink) time Tm is curtain motor operation, window size is S,
The fixed speed of service of motor is V, by operation total distance S=V*Tm.It only needs that Tm numerical value is arranged, so that it may be applicable in different in width
Window size.
Single step stroke/total kilometres (1/n): single step run time Tn=Tm/n (n is integer, n >=1), the fixed operation of motor
Speed is V, then curtain range ability be L=Tn*V=Tm/n*V=S/n (n is integer, n >=1), pass through setting single step row
Journey/total kilometres parameter is n parts of progress single step runs total distance S points.
Downgoing time difference △ T: common curtain motor has longitudinal movement and transverse movement type, wherein since curtain itself has
Gravity influences, A) in transverse movement type curtain, transverse direction remains a constant speed movement.Downgoing time difference △ T should be set as
0；
B) in longitudinal type curtain, window size is fixed as S, curtain fixed speed V, closes (downlink) time Tm；Vertical
To uplink, curtain gravity G can hinder curtain uplink, lead to speed uplink Vup < fixed speed V, can since S is fixed size
S/Vup > S/V is obtained, i.e. upstream time Tup is greater than downgoing time Tm.By the way that downgoing time difference △ T is arranged, when uplink is appropriately extended
Between, Tup=Tm+ △ T to support longitudinal type curtain motor, and can be reduced error caused by gravity.
Stroke positioning:
In DALI agreement, current power level LVo reflects equipment current state, the power grade LV model of user setting
Enclosing is 0-254, in different windows, using fully open state as maximum power level 254, using completely closed state as
0 grade after configuration parameter, is opened (uplink) time Tup and closes downgoing time Tm, need to be arranged according to user corresponding
Power grade LV, and according to current power level LVo, calculate change of rank △ LV；
△ LV=LV-LVo；
Change of rank △ LV is converted to motor operating time TLV, realizes stroke control and positioning function.
For lateral type curtain motor, opens (uplink) time Tup and be equal to closing downgoing time Tm, total travel time T
=Tup=Tm；When LV > 0 △, controls motor and open (uplink) channel runing timeReach setting grade
LV, and record present level LVo=LV；When LV < 0 △, controls motor and close (downlink) channel runing timeSetting grade LV is reached, and records present level LVo=LV；
Corresponding longitudinal direction type curtain motor, opens (uplink) time Tup=and closes downgoing time Tm+ downgoing time difference △ T；
Up stroke total time: Tup=Tm+ △ T downward storke total time: Tm；When LV > 0 △, controls motor and open (uplink) channel fortune
The row timeSetting grade LV is reached, and records present level LVo=LV；When LV < 0 △, motor is controlled
Close (downlink) channel runing timeSetting grade LV is reached, and records present level LVo=LV；
It by DALI curtain driver, can be arranged according to user demand, and control motor operating time, realize the positioning of curtain stroke.
The utility model it is structurally reasonable, can by electrically driven curtain access DALI system, realize parameter configuration and control connection
It is dynamic, be conducive to the precision for improving control, while connecting by DALI signal bus, be conducive to the route of simplified control, improves control
The efficiency of system, stability in use are good and practical.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
Exhaustion.And the obvious changes or variations that these connotations for belonging to the utility model are extended out still fall within it is practical
Novel protection scope.
