Below in conjunction with accompanying drawing the utility model is described in further details.
The utility model comprises rotating mechanism, emitter, the receiver of door.The rotating mechanism (as shown in Figure 1) of door is to adopt to be provided with metal runners 2 on the side of turnover panel 1, pivoted arm 3 one end devices are in metal runners 2, the other end is fixedly connected with the change-speed gearing 4 that is fixed on the garage interior wall, change-speed gearing 4 is meshed with the worm gear 5 that has worm screw 6, worm screw 6 is fixedly connected with motor 7, and motor 7 links with the relay of receiver 8.After receiver 8 is received signal, translate corresponding work order by decoder, motor rotates, and drives pivoted arms 3 by worm gear 5, worm screw 6, change-speed gearing 4 and makes and open or close.Motor adopts 4 grades of single-phase capacitance starter motors, changes to per minute 6 by worm gear 5, worm screw 6 speed changes, also can establish a manual driving lever on change-speed gearing 4, makes it break away from worm gear 5 during power failure, gets final product manual operation.
The emitter critical element adopts address input end, its circuit block diagram as shown in Figure 3, circuit interconnect pattern as shown in Figure 5, it comprises Ic 1, Ic 2, coil L 1, L 2, L 3, capacitor C 1, C 2, C 3, diode D 3～D 7, K switch 1～K 8The pulse signal output of encoder makes corresponding pulse signal launch by the carrier frequency oscillation circuit by the work of modulator control carrier-frequency oscilaltor.For adopting the electronic switch controlled encoder service time of conserve batteries, emitter (as shown in Figure 2) knob 9 can corresponding as required K 1～K 8, indicator lamp 10 respective leds D 1, the coded pulse frequency is about 1000Hz, and the carrier frequency oscillation frequency is about 300MHz, and transmitting power is decided according to the work-yard.The decoder of receiver and transmitter coding device adopt the integrated circuit that compiles of same model, as UM3750, UM3758-108A/AM.
The receiver circuit block diagram as shown in Figure 4, Fig. 6 is the receiver circuit wiring diagram.The L of the superregenerative detection circuit of receiver 1Coil processing can make more stable work in the circuit board.Adjust C 2Can change frequency of oscillation, L 2Be the high frequency retardation coil, R 5Be the load of superregenerative detection circuit, the audio signal after the detection (pulse signal) is passed through R 4, C 8Coupling and be added to amplifying stage, and adopt the high homophase AC amplifier of input impedance, identical to shaping circuit and paraphase again after amplifying through two-stage with the phase place that emitter sends, so that decoding circuit translates corresponding yard.Decoder I is mainly by Ic 3, R 19, R 31, C 17Form, output Ic18 angle is connected R in decoder input and the shaping circuit 30With C 17The frequency (identical) of decision pulse with emitter.
During work, when pressing emitter knob 9 and send enabling signal I (coding), decoder Ic 317 pin have one
Figure Y9523154600071
The pulse output of negative saltus step makes triode G 2Conducting, capacitor C 19By diode D 2, triode G 2Discharge makes Ic 26 pin compare Ic 25 pin current potentials are low, Ic 2At this moment 7 pin output high level as not pushing the wrong pseudo-code key, Ic 2B8 pin output high level makes diode D 3Oppositely and not influence triode G 3Conducting, at this moment Ic 2a7 pin output high level makes triode G 3, G 4Conducting J 1Adhesive makes one of two switch connection of connecting in the circuit that opens the door.Meanwhile, by diode D 5, make the lock-in circuit Ic of the circuit b that opens the door 2C2 pin clamper electronegative potential makes Ic 2C1 pin output high level, this makes diode D 7Oppositely give the ready signal of circuit b that opens the door, signal is held time by W 1, C 13Decision, this machine setting up time is 3-5 second, when pressing enabling signal II (coding) in the meantime, the Ic of decoder III circuit 517 pin just have one
Figure Y9523154600072
Negative pulse output makes triode G 6End triode G 7Conducting, switch J 2Open the door another switch connection of circuit of adhesive, biswitch.At this moment, the rotating mechanism that opens the door just can be started working, and rotates by the relay motor, and door is opened.
If the user does not correctly send enabling signal II at 3-5 in second, or when sending signal II after 5 seconds, comparison circuit has turn-offed Ic because of at this moment delaying time 27 pin output low levels make triode G 4End diode D 5Oppositely, Ic 2C2 pin high potential, Ic 2C1 pin output electronegative potential makes triode G 7Base stage clamper electronegative potential, even triode G at this moment 6End G 7Can not conducting, so switch J 2Can not adhesive.
If it is strong that the user has pushed the wrong pseudo-code, make decoder II circuit I c 417 pin are jumped
Figure Y9523154600081
Negative level makes triode G 5Conducting, capacitor C 23By diode D 6, triode G 5Discharge makes Ic 2The b10 pin is lower than 9 pin, Ic 28 pin output low levels are by diode D 3Make triode G 3The base stage clamper to ground, make the circuit a that opens the door protected.Even at this moment by right enabling signal I, because of triode G 3Can not conducting, G 4Not conducting, switch J 1Can not adhesive.The pseudo-code delay time by variable be the resistance W 2, capacitor C 23Decision, it is 3 minutes that embodiment selects delay time, could operate as normal after the pseudo-code delay circuit recovers by the time.
If the user sends when closing gate signal, by decoder IV circuit I c 717 pin output negative level.Make triode G 8, G 9Conducting, switch J 3Adhesive, the action of closing the door.Equally, all right emission switch modulation code of user, decoder Ic 617 pin output negative level makes triode G 10, G 11The bistable circuit upset, G 12Conducting, switch J 4Adhesive, lighting circuit is connected, and by sign indicating number, lamp is just turned off once more.
The outage back is at incoming call instantaneous (referring to line voltage), and receiver circuit has defencive function.During incoming call, the pseudo-code delay circuit is just started working, at W 2, C 23, Ic 2The circuit delay time of b has surpassed the delay time of the circuit a that opens the door, though when work just Ic 2A7 pin output high level, but triode G 3By diode D 3Institute's clamper, triode G 3Can not conducting, so played protection switch J when sending a telegram here in moment 1, make it can not adhesive.
Diode D 10Output Kn point can connect next combination lock circuit, to increase the multidigit combination lock.
