Description
The utility model relates to needed a kind of sub-ultrasonic remote-control curtain in the indoor daily life of people.
The develop rapidly of current electronic technology is for the telecontrol engineering field provides varied, multicoloured control device, to the remote control of indoor curtain in the daily life, the radio single channel successively appearred, program time control, light-operated or the like, but all fail large-area popularization.Trace it to its cause, though automatic light-operated advanced, can not embody owner's wish at any time; Program control time control also is like this; Though wireless remotecontrol can be worked at any time, because of the circuit complexity, the cost height can not large tracts of land be promoted, and radio wave is operated in very high frequency(VHF), and to disturb this mutually with television frequency also be a difficult problem; Though adopt the infrared remote control mode to prove effective, the experiment proved that, as at infrared receiving tube front lastblock fabric, will dwindle its command range greatly, furthermore one indoor with two infrared transmitters, the phenomenon of interfering TV is always arranged.
In order to overcome the deficiency that exists in the prior art, the utility model has adopted the sub-ultrasonic remote-control technology, its objective is to design to have comprehensive reception, and strong interference immunity, price is low, a kind of sub-ultrasonic remote-control curtain of can popularly promoting, conveniently using.
In order to achieve the above object, sub-ultrasonic remote-control curtain of the present utility model, on the basis of existing curtain frame for movement, controlling organization has adopted the receiver of gasbag-type transmitter and the inferior ripple switch of SK-1 supporting, with 19 kilo hertzs frequency, have omnibearing reception, human body there is not bad injury, and differ greatly with radio wave frequency, infrared frequency, can not form the ideal control source of interference; The reliable turn-off when sending a telegram here again in order to guarantee to have a power failure and the sensitivity of control have been set up the relay that adopts two H contacts in circuit, and with the commutation of control motor, motor and receiver have adopted the dual power supply mode; Replaced the travel switch in the prior art in time to cut off motor power in order to reduce cost with microswitch.
For structure and principle to the utility model sub-ultrasonic remote-control curtain have further understanding, details are as follows in conjunction with an embodiment of the present utility model:
Embodiment, the sub-ultrasonic remote-control curtain
With reference to accompanying drawing, the structure of subultrasonic remote-controlling window curtain of the present utility model has comprised institute among the figure Show, between two steel lacing films (1) that the window frame side walls is fixed, connecting The flitch of 30 * 30mm (2), be fixed wtih by two rail brackets (3) at flitch (2) with The window width hangs with some with long I shape track (4) on the lower eaves of I shape track (4) Individual duplex bearing Curtain suspension device (5) is provided with two curtain rod carriages (7) in the both sides of I shape track, And microswitch (8), the double window cord (6) that duplex bearing Curtain suspension device (5) lower end is connecting The termination is connected with curtain rod carriage (7) again, hangs the car formula of pulling on I shape track (4) one ends Electrical appliance kit in be provided with motor, decelerator (11), relay (12), transformer (13), electricity Machine is direct current generator (also available alternating current generator), and decelerator is the deceleration in the pawl formula alternating current generator Device, be provided with driving pulley (14) at its output shaft, curtain rope (9) is around being fixed on the worker On the follow-up pulley of font track end (10) and the driving pulley (14), and be connected with carriage (7), When machine operation, curtain rope (9) spurs curtain rod carriage (7) under the drive of two pulleys Promote duplex bearing Curtain suspension device (5) and double window cord (6) in the upper two-way fortune of I shape track (4) OK: for preventing the mechanical rotation part to the interference of control system, the inferior ripple switch of SK-1 receives Machine (15) is contained on the suitable wall behind the curtain, with its supporting being moulded by a spherical envelope and The gasbag-type transmitter (16) that the material mouthpiece consists of belongs to passive transmitter, and it mainly is by extruding Air bag sends the inferior pulsed ultrasonic wave of radiation, and the on-off circuit in the control receiver changes.
The control electricity principle of this sub-ultrasonic remote-control curtain as shown in Figure 3, receiver adopts capacitor C 1 step-down, in the hope of reduced volume, D1-D4 is full-wave rectification, C2 is a power filter, BG1 and R2, S, C3, L forms the frequency-selecting amplifying stage, the shunt-resonant circuit that C3 and L form is connected in the collector loop of BG1, prevented the misoperation that causes by stray wave, in order further to improve anti-interference, adopted inferior ultrasonic transducer S with selecting frequency characteristic, resistance R 2 is set up the operating point for S and BG1 simultaneously, BG2 constitutes the pulse shaping level, be operated on off state, R3 promptly is the collector load resistor of BG2, again as the discharge loop of C5, BG2 is in cut-off state at ordinary times, has only when S receives inferior ultrasonic signals, and the BG1 colelctor electrode has AC signal output, be coupled again through the D5 halfwave rectifier through C4, for BG2 provides base bias, BG2 begins interrupted conducting, gives the C5 quick charge through R4 during the BG2 conducting, because the charge circuit resistance R 4 of C5 is much smaller than discharge loop resistance (R4+R3), therefore it is steep to form the forward position at the two ends of C5, the back is along slow positive pulse, with this pulse as BG3, the trigger impulse of BG4, BG3, BG4 constitutes typical bistable circuit; Relay J can be turn-offed reliably when sending a telegram here again in order to guarantee to have a power failure, and this circuit has adopted incomplete symmetric mode, and BG3 is by, BG4 conducting at ordinary times, and BG5 does not have base bias, not conducting, and relay J discharges; When signal is arranged, the BG3 conducting, BG4 ends, and R9, R11 provide base bias for BG5, and the BG5 conducting provides the promotion electric current for relay J and LED, the relay adhesive, LED is luminous, promptly serves as the conducting indication, serves as current-limiting resistance for relay again; D8 mainly is that the induced voltage for relay J provides bleed-off circuit, and BG5 is not breakdown in protection; Relay J adopts two H contacts, and during the relay adhesive, normally opened contact is connected, and motor a point is just, b point is negative, and motor just changes, and when relay discharged, normally-closed contact was connected, a point is born, the b point just, motor reverses, the stopping of motor controlled by microswitch (8) K1, K2; Sensitive, reliable for guaranteeing control, this machine adopts the dual power supply mode, be that receiver is directly powered by capacitor C 1 step-down, motor is then by power transformer B transformation independently, directly power supply after the rectification, in the time of can having exempted single power supply like this because electric motor starting, voltage die and the out-of-control phenomenon that brings, the capacitor C 8 that is connected between motor a, b contact is to eliminate the interference that electric spark brings.
Subultrasonic remote-controlling window curtain novel structure of the present utility model, easy to use, it is with existing Any remote-controlled curtain suspension in the technology is compared has omnibearing reception, and control is sensitive, is not subjected to appoint The characteristics such as what ripple disturbs frequently, and price is low, and power consumption is few, its quiet worker's consumption is less than 0.5W, and is moving The highest 3W of power consumption, noiselessness does not have harm to human body, is a kind of very competitive product, This subultrasonic remote-controlling window curtain can large-arealy be generalized to should in family, hotel and the big or small meeting room With.
