Abstract

A power supply switch laser remote control is provided, which comprises a shell, and a circuit board in the shell, and is characterized in that: the circuit board comprises a transformation circuit and an optical control relay; the transformation circuit converts an AC power supply into a DC power supply for supplying an preliminary optical control relay; the optical control relay consists of an optical sensor connected in series with a signal integration circuit, a flip-flop, and a relay. When the optical sensor receives the laser, the resistance value is reduced, and the voltage is also reduced, the trigger signal generated by the signal integration circuit is sent to the flip-flop, after received the signal, the flip-flop changes the state, facilitate the relay changing to another state, and the relay can be switched on or off, thereby rendering the lamp or electrical appliance equipment being opened or closed. The remote control has small volume, easy operation, unlimited by the frequency, high exchangeability, and the application range is widened.

Description

The laser remote-controlled device of mains switch

Technical field

The utility model relates to the laser remote-controlled device of a kind of mains switch.

Background technology

Traditional mains switch is a hand touch-control push-button switch.For handicapped or can't go to for the moment the people at switch switch place, very inconvenient, even puzzlement.The present infrared telecontrol switch that uses, but long-distance remote control.But because of its frequency needs button of a switch, a plurality of frequencies of a plurality of switches need a plurality of buttons, and button causes volume big and be easy to confusion more, need the pairing of each switch of memory and each button, so cause operation inconvenient.

Summary of the invention

The purpose of this utility model is to avoid the shortcoming of infrared telecontrol switch, provides a kind of volume mains switch little, easy to use laser remote-controlled device.

The technical solution of the utility model is: the laser remote-controlled device of mains switch, comprise the circuit board in shell, the shell, and comprise transforming circuit and photorelay on the circuit board; Transforming circuit is converted to DC power supply with AC power, for should photorelay; Photorelay is connected in series signal integrated circuit, flip-flop, relay successively by optical inductor.When optical inductor is accepted laser, its resistance diminishes, the voltage of signal integrated circuit is also diminished, signal integrated circuit produces negative edge triggering signal and delivers to flip-flop, thereby change state behind the flip-flop acknowledge(ment) signal, making relay is another kind of state by original state-transition, thus relay conducting or stop, and make light fixture or electric equipment open or close.Because the switching of photorelay, the conducting of controllable power or end on the application socket, can form a kind of laser remote-controlled socket.

The more conventional infrared telecontrol switch of the utility model, have following good effect: 1, remote controller is little: a laser can be at all switches.Do not resemble switch of infra-red remote control and want a button, a plurality of switches are wanted a plurality of buttons.2, processing ease: all available single LASER Light Source control of any switch does not resemble the pairing that infrared ray will be remembered each switch and each button.3, omnipotent: can thousands of switches of remote control, and also laser range is far away, can reach hundreds of rice, and easy in the large space remote control.4, substituting height: infra-red remote control is subjected to frequency limitation, and remote controller has fallen, other can not be substituted, and laser remote-controlled device is unrestricted.

Description of drawings

Fig. 1 is the utility model circuit structure schematic diagram;

Fig. 2 changes DC circuit figure for exchanging;

Fig. 3 is the utility model embodiment circuit diagram.

Embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

Shown in Figure 1, its circuit mainly is made up of transforming circuit 1 and photorelay 2, and wherein, photorelay 2 is connected in series signal integrated circuit 22, flip-flop 23 and relay 24 successively by optical inductor 20 (push-button switch 21).Shown in Figure 2, transforming circuit 1 is D.C. regulated power supply with AC power through rectifying pressurizer 25 rectifications, with supply photorelay 2.

Figure 3 shows that an embodiment, optical inductor 20 is connected transforming circuit with push-button switch 21; One line of optical inductor connects 3,4 pin of signal integrated circuit 22, and its No. 6 pin one lines connect No. 3 pin of flip-flop, and No. 1 pin of flip-flop is connected in series a resistance R 4, triode Q1, links to each other with relay 24 then; No. 2 pin of flip-flop 23 connect a LED26, and 5, No. 6 pin connect power supply.

The effect of optical inductor 20 is an induction laser, its resistance can diminish, voltage also can diminish, impel signal integrated circuit 22 to produce triggering signal, make flip-flop 23 change its state, thereby make relay 24 change states, carry out conducting or, make the power supply of its On/Off light fixture or electric equipment by the action of power supply.

During the optical inductor 20 of laser radiation to photorelay 2, need not adjust light frequency, focusing and direction scope, only need laser radiation, can operate and reach application target.

In sum, the design has changed infrared remote controller and has been subjected to characteristic frequency restriction and distance not far, and a plurality of switch needs a plurality of buttons, volume is big and be easy to chaotic shortcoming, and not only volume is little, and is easy to operate, all character switches of a light source may command are more arranged, remote control distance height far away, substituting.
