Description

The visible light electronic romote-controller

The utility model relates to a kind of visible light electronic romote-controller of being made up of jointly with the circuit arrangement of exciting curent relay and supply relay in the electricity field.

As everyone knows, the household electrical appliance remote controller of function admirable can be given huge numbers of families, especially bring convenience for old man, children and noneffectives, simultaneously family room is beautified.Common maximum have Infrared remote controller and ultrasonic electronic telepilot.But infrared coding remote is not suitable for household electrical appliance (as the light fixture etc.) characteristics that set disperses, and the general emissive power of simple infrared remote control is little, is difficult to reach practical function.And infrared ray is an invisible light, promptly enables far distance controlled, and non-coded telecommand is inevitable, and the troublesome problem of whether " aiming " often takes place.The defective of ultrasonic electronic telepilot is, a plurality of controlled devices are not had selectivity (because of control signal is propagated to space radiation), and this just greatly limits its use amount and range of application.Utilize visible light to carry out the light-operated circuit of remote control in the prior art, it is having or not light, or the brightness size of the light of saying so is as the condition of circuit state variation, sort circuit is made the telepilot of household electrical appliance, be easy to be subjected to light stable (being bias light) and normally turn on light or turn off the light the interference that forms and produce misoperation, so very difficultly generally apply in practice.

The purpose of this utility model, be provide a kind of adopt common flashlight as emission element simple and practical, convenient and easy, resolution is high, selectivity and the good visible light electronic romote-controller of anti-interference.

Solution of the present utility model is as follows.It still comprises signal emission part and signal receive section, and its feature part is, signal emission part is made of common flashlight, signal receive section can be referring to Fig. 1 electricity functional-block diagram, it is received and photoelectric switching circuit 1 by visible light pulses, electric pulse treatment circuit 2, control voltage forming circuit 3, bistable circuit 4, current amplification circuit 5, relay circuit 6, ac buck and rectification circuit 7 and mu balanced circuit 8 are formed, wherein the visible light pulses reception and the output terminal of photoelectric switching circuit 1 and the input end of electric pulse treatment circuit 2 join, the output terminal of electric pulse treatment circuit 2 links to each other with the input end of control voltage forming circuit 3, the input end of bistable circuit 4 is connected on the output terminal of control voltage forming circuit 3, the output terminal of bistable circuit 4 is connected in the input end of current amplification circuit 5, the line bag of relay circuit 6 repeat circuits is connected on the output terminal of current amplification circuit 5 as load, the output terminal of ac buck and rectification circuit 7 is connected to mu balanced circuit 8, and also provide dc supply to current amplification circuit 5 and relay circuit 6 simultaneously, the output terminal of mu balanced circuit 8 then receives and photoelectric switching circuit 1 to visible light pulses, electric pulse treatment circuit 2, the power end of control voltage forming circuit 3 and bistable circuit 4 provides the DC voltage-stabilizing working power.

The utility model with foregoing circuit structure is when concrete the use, the input end of ac buck and rectification circuit 7 is connected on the 220V electric main, provide working power with the circuit of giving receiving unit, also need simultaneously with relay circuit 6 repeat circuits moving close, the relative section of equipment such as break contact and controlled household electrical appliances links to each other.Hand-held common flashlight is as the radiating portion of telepilot, launching a monopulse light signal artificially is steering order, promptly set with the sensor (photosensitive device) in reception of beam flying (streaking) visible light pulses and the photoelectric switching circuit 1, form one by secretly to bright, get back to dark light pulse signal again again, as the distinguishing mark of this circuit 1.Be far from it, other any light stables and the formed undesired signal of normally turning on light, turn off the light, circuit 1 is refused " showing interest in ".Make its degree that reaches capacity so long as not intense light source (as sunshine, high-power incandescent light) direct light sensing device, circuit 1 can operate as normal.Circuit 1 converts the light pulse signal that receives to electric impulse signal and is defeated by electric pulse treatment circuit 2 again, further discern and handle by the command pulse signal after 2 pairs of conversions of this circuit, its reproduced pulse signal is given control voltage forming circuit 3, to form control signal output, this output signal is delivered to the input end of next stage bistable circuit 4, making bistable circuit 4 outputs one steady state voltage signal carry out electric current for current amplification circuit 5 amplifies, current signal after this amplification is given the line bag of relay circuit 6 repeat circuits, make relay get electric adhesive, its moving closing, the break contact action starts controlled device work.Stop controlled device work as need, then send visible light command pulse signal with electric torch again, make bistable circuit 4 export to another kind of stable state from existing stable state output switching activity, cut off the exciting curent of exporting to relay line bag with Control current amplifying circuit 5, so relay electric-loss discharges, it moves and closes, the break contact action, stops controlled device work.

The utility model telepilot adopts common flashlight as radiating portion, has saved dedicated transmitter, has reduced the manufacturing cost of whole telepilot, generally promotes the use of easily; Torch light drop point is high-visible, and command range is far away, uses directly perceived, convenient; The orientable emission of torch light, receiving circuit is novel in design rationally, has high resolving power, good selectivity and anti-interference, reliable operation.
