The present invention includes and comprise remote controller and aircraft, aircraft includes the executing agency that carries out remote control actions for driving aircraft, it is characterized in that: remote controller includes luminous tube, is used for emission and can shines remote control light beam aircraft, that can move at aircraft fuselage; Aircraft includes for the light-sensitive element that receives the remote control light beam; Identify the moving direction of remote control light beam and control the control circuit of executing agency according to remote control light beam moving direction according to the light-sensitive element input signal with being used for; Light-sensitive element is connected to the control circuit input; The output of control circuit is connected to executing agency.(the remote control light beam is sometimes also referred to as light beam in present specification).
The remote control light beam of described remote controller emission is the cylindricality light beam, or cone-shaped beam.These light beams adopt the luminous tube electrified light emitting to produce optically focused through concentration structure again and form, and this belongs to electrooptics aspect common technology.
The movement of described remote control light beam, or claim to sweep, brandish, be the movement towards the space different directions on the same sensitive surface of aircraft of remote control light beam.Comprise move down, up mobile, toward move left, toward move right, the movement of light source (being the remote controller luminous tube) flyby device and the movement that light source leaves aircraft.The remote control light beam is to mobile corresponding the specific remote information of each direction.Same sensitive surface namely is a face that can be subject to simultaneously the remote control light beam irradiates.
For the remote control that realizes that aircraft rises and descends, at first aircraft executing agency includes for the lifting executing agency that drives the aircraft lifting, the present invention is provided with two light-sensitive elements that are used for receiving the remote control light beam at least at the diverse location of the above-below direction (also be vertical direction, be equivalent to the Y-axis of coordinate system) of the same sensitive surface of aircraft fuselage side; Control circuit is according to the precedence of the input signal variation of light-sensitive element on the diverse location, identify the moving direction of remote control light beam on above-below direction, be that light beam moves down or up mobile, identify the remote control intention with this, the output of control circuit is connected to lifting executing agency, and does corresponding action by lifting executing agency driving aircraft.
For the remote control that realizes that aircraft turns left and turns right, at first aircraft executing agency include for drive the aircraft left/right rotation to turn to executing agency, the diverse location of the left and right directions (also be horizontal direction, i.e. X-axis) of the present invention on the same sensitive surface in aircraft fuselage side is provided with two light-sensitive elements that are used for receiving the remote control light beam at least; Control circuit is according to the precedence of the input signal variation of light-sensitive element on the diverse location, identify the moving direction of remote control light beam on left and right directions, comprise toward moving left or past moving right, the output of control circuit is connected to and turns to executing agency, and does corresponding action by turning to executing agency to drive aircraft.
For realizing the move forward and backward remote control of (or halting) of aircraft, at first executing agency includes for the control aircraft and does the executing agency that advances that advances or retreat, control circuit of the present invention is according to the variation of the signal strength signal intensity of the same light-sensitive element that arranges on the aircraft fuselage, identify the remote control light beam on the direction of advance (also namely on the rectilinear direction of remote controller and aircraft, be equivalent to Z axis) moving direction, comprise the movement of light source flyby device, or light source leaves the movement of aircraft; The output of control circuit is connected to the executing agency that advances, and does corresponding action by the executing agency's driving aircraft that advances.
The present invention is suitable for going straight up to the class aircraft in the remote control of indoor or outdoors closer distance.Operator's hand-held remote controller sends the remote control light beam during use, brandishing remote controller according to the remote control intention makes the remote control light beam irradiates also produce movement to aircraft fuselage, the control circuit of aircraft receives the remote control light beam by light-sensitive element, identify its moving direction, also namely identify operator's remote control intention, and make corresponding actions by executing agency's driving aircraft.Such as the mobile recognition technology that adopts simultaneously above-mentioned X, Y, three directions of Z axis, can realize the remote control of MIMD: the remote control light beam is covered shine aircraft fuselage (so that light-sensitive element all receives light beam simultaneously) and when not moving, aircraft keeps vacant state; During with the bottom-up inswept aircraft fuselage of remote control light beam, the aircraft main screw accelerates to make aircraft to rise; From up to down during inswept aircraft fuselage, main screw slows down aircraft is descended with the remote control light beam; When the direction of remote control beam light source from the aircraft back to the flyby device moved, aircraft travelled forward; When the light source of light beam is moved to the direction of leaving aircraft, aircraft retreat or halt (for the aircraft that does not have fallback state); When sweeping about the remote control light beam, aircraft turns to (being fit to have left/right rotation to the aircraft of executing agency) to the left and right; Then aircraft does not keep original various state when having light beam irradiates.
The present invention with traditional remotely-piloted vehicle relatively, the advantage that has is: 1, the operator need not button or the action bars of bimanualness remote controller, also need not accurately to aim at light-sensitive elements different on the aircraft, make the remote control light beam mobile to the different directions generation on fuselage but brandish remote controller according to remote control intention one hand, realize remote control to aircraft with intuitively action, so straighforward operation is extremely directly perceived and easily simple, especially is fit to the little children of age and uses; 2, remote controller is just launched the remote control light beam, remote information is not included in the light beam the inside, but transmitted by the moving direction of light beam, so circuit is extremely simple, be exactly that the power drives luminous tube is luminous, do not need button and action bars, it is more reliable to work, and the remote controller profile can do very little very flexibly, such as making elongated remote control rod, baton, conjury stick, so that the richer interest of toy remote control.
The remote control light beam of remote controller emission can be visible light beam or infrared beam, perhaps comprises simultaneously both beam combinations.Its operation principle is the same, different just luminous tubes, and supporting light-sensitive element on the aircraft.In fact a lot of light-sensitive elements can be suitable for visible light and infrared ray simultaneously, and just the filter of light-sensitive element front is different.Adopt visible light beam can see the remote control light beam, operation control is more directly perceived and easier, is fit to children's use that various crowds comprise little age; Use infrared beam anti-interference better, but cannot see the remote control light beam, some difficulty are arranged, if also be straightline propagation but the operator understands infrared ray, just can be with the movement of feeling to hold the control light beam, and cannot see light beam when using, only see that arm or remote control rod in that brandish just can remote-control toy, more have strange sensation and interest.When the remote control light beam adopts visible light beam, for fear of the interference of ambient light, should not adopt white light, adopt the light beam of ruddiness or green glow or blue light or purple light first-selectedly.Correspondingly be added with redness or optical filter green or blue or purple in carry-on light-sensitive element front.Adopt colored light beam can improve the anti-interference of remote control.Also can launch infrared beam and transmit the remote control intention, launch simultaneously visible light beam and come the reference location for the operator, and make both optically focused become same beam combination together, reach again easy-operating advantage directly perceived of existing anti-interference.
As further improvement, the control circuit of aircraft receives the remote control light beam by light-sensitive element, identifies direction and speed that the remote control light beam moves; And according to direction and speed that the remote control light beam moves, control executing agency and carry out remote control actions with friction speed.To the identification of light beam translational speed, can be the translational speed of identifying time difference of the signal intensity of the light-sensitive element by diverse location the remote control light beam, be applicable to move at the light beam of left and right directions (being X-axis) and above-below direction (being Y-axis); Or the rate of change by change in signal strength on the light-sensitive element, identify the translational speed of remote control light beam, be applicable to aircraft and remote controller and move at the light beam of rectilinear direction (being Z axis).This improvement makes aircraft can brandish according to the operator speed speed of remote controller light beam, control the speed of execution action, make the light beam inswept aircraft that makes progress fast such as upwards brandishing fast remote controller, aircraft fast rise then, slowly upwards brandish remote controller and make the light beam inswept aircraft that slowly makes progress, then the aircraft climbed is realized the remote control with analog quantity.Requirement according to the control of different toys can arrange different progression to the quantification of this analog quantity, such as tens grades, in general, to the responsiveness of most flying toy, 3 grades (namely fast, neutralization slowly) are set, and can meet the demands.This improves with simple method, realizes the remote control to aircraft band analog quantity, makes distant control function more powerful abundanter, and remote controller need not to adopt complicated band potentiometer action bars, also need not to increase circuit, and straighforward operation is simple, intuitive especially, and is more joyful.

The specific embodimentThe below to how implementing the present invention describes with reference to the accompanying drawings.
Need to prove, the object of the invention is to disclose a kind of operation easy band remotely-piloted vehicle more directly perceived, and for realizing correlation technique of the present invention, executing agency such as aircraft, by motor cooperative mechanical structure drive aircraft carry out rising, decline, unsettled, advance, retreat, left/right rotation to action, belong to existing toy technique.Carry-on control circuit of the present invention, except including the identification circuit for identification light beam moving direction or translational speed, generally also include the control signal of identification circuit output is carried out power amplification in order to drive the drive circuit of executing agency's action.And some basic functions of circuit involved in the present invention, comprise detection to the reception of light and intensity, to modulus (A/D) conversion of voltage signal and computing relatively, by adjustment operating voltage or the PWM pulsewidth modulation control to machine operation power and rotating speed, comprise how adopting single-chip microprocessor MCU or DSP or other circuit according to operation principle of the present invention and method is designed physical circuit and program is carried out work, the common technology that all belongs to electronic technology field and toy remote control, the present invention does not do and is described in detail.And for simplicity, the circuit diagram of accompanying drawing of the present invention only draws with the relevant element of operation principle, other circuit parts such as power supply, filtering, clock, reset, input anti-interference, the interlock circuits such as the power amplification of output and driving belong to general knowledge, also do not draw.
Fig. 1 is operation principle schematic diagram of the present invention.The present invention includes remote controller 1 and aircraft 2, the a branch of remote control light beam 3 that can shine aircraft 2 of operator's single-hand handling ﹠ remote controller 1 emission during use, and brandish remote controller according to remote control intention, it is mobile that remote control light beam 3 is produced at aircraft fuselage, or claim to sweep, brandish; Aircraft 2 is by the light-sensitive element receiving beam 3 on the fuselage, and the electronic circuit of aircraft identifies the moving direction of remote control light beam, controls the action of aircraft with this.The light beam of remote controller emission can be that light connects subparallel cylindricality light beam, or light is the cone-shaped beam of low-angle diffusion.Remote controller adopts power drives luminous tube such as the luminous again process of LED optically focused to form light beam, belongs to electrooptical technology commonly used.The light beam irradiated area is less when adopting the cylindricality light beam, and light is concentrated, and can carry out longer-distance remote control, typically can adopt or with reference to the multimedia teaching laser pointer with the low-power laser pipe commonly used; What Fig. 1 adopted is cone-shaped beam, and the irradiated area of cone-shaped beam is larger, can more easily shine with it the toy machine, and handled easily can adopt or the various compact LED flashlights with optically focused of reference.
Aircraft includes light-sensitive element, control circuit and is used for driving the executing agency that aircraft is carried out remote control actions.Light-sensitive element is installed on the aircraft fuselage, generally is on the fuselage side, so that when work shone easilier by the remote control light beam.The light-sensitive element front generally also is added with the corresponding colour filter of remote control light beam, just cooperates Red lightscreening plate such as red remote control light beam, (some light-sensitive element self is with optical filter).Light-sensitive element is exported different electrical signals and is delivered to control circuit according to the different conditions of illumination.Control circuit identifies the moving direction of light beam according to the signal intensity of light-sensitive element, identifies the remote control intention with this, drives executing agency and carries out corresponding actions.How to identify the moving direction of remote control light beam for control circuit, and identify the remote control intention and aircraft is controlled with this, the below is described in detail this.
For the remote control that realizes that aircraft rises and descends, at first aircraft executing agency includes lifting executing agency, namely connects main screw by main motor and drives the action that aircraft is done rising and descended; The scheme that the present invention adopts is: the diverse location at the above-below direction (being vertical direction, also is Y-axis) of the same sensitive surface (namely can be subject to simultaneously a face of light beam irradiates) of aircraft fuselage side is provided with two light-sensitive elements that are used for reception remote control light beam at least; Control circuit is identified the moving direction of remote control light beam on above-below direction according to the precedence of the signal intensity of light-sensitive element on the diverse location, identifies the remote control intention with this, and corresponding action is done by control lifting executing agency.Object lesson such as Fig. 2, aircraft 4 at aircraft 4(Fig. 2 is the flight ball) on the same sensitive surface of the side of fuselage, be respectively arranged with light-sensitive element G2 and G3 in two positions of above-below direction, receive mobile change of remote control light beam on above-below direction.Its toy circit such as Fig. 3.Light-sensitive element G2, G3 respectively series resistance R2, R3 consist of 2 road light beam receiving circuits, and its output is connected to input IO2 and the IO3 of the single-chip microprocessor MCU 2 of control circuit.MCU2 identifies the moving direction of remote control light beam according to the voltage change of IO2 and IO3, export corresponding control signal, control circuit generally also includes the drive circuit that the MCU2 control signal is carried out power amplification, the output of drive circuit is as the output of control circuit, be connected to lifting executing agency, drive aircraft by lifting executing agency and carry out lifting action.MCU2 can adopt various general single chips without specific (special) requirements.
For the identification of remote control light beam moving direction, the present invention discloses following two kinds of concrete recognition technologies.
The first recognition technology is under the prerequisite that all do not shone by the remote control light beam of the light-sensitive element at the same sensitive surface diverse location of aircraft, and the precedence that control circuit receives the remote control light beam irradiates according to the light-sensitive element of diverse location is identified the moving direction of remote control light beam.G2 and G3 are not subject to light beam irradiates when namely beginning yet, and G2 and G3 dark resistance are very large, and with the very low voltage of output behind the electric resistance partial pressure, the at this moment IO2 of MCU2 and IO3 input all is low voltage signal, as original state.Then when light beam from the periphery inswept toy, the precedence that is subject to light beam irradiates according to G2 and G3 is identified the moving direction of light beam.When light beam being bottom-up inswept G3 and G2, then G3 and G2 successively receive of short duration light beam irradiates, light resistance became very little when G3 and G2 were subject to light beam irradiates, so IO3 and IO2 be the high input voltage pulse signal successively, so it is bottom-up movement that MCU2 identifies light beam with this, the output of control circuit drives lifting executing agency, heightens the rotating speed of the main screw motor of aircraft, thereby aircraft is risen.Length according to time difference (also being the time interval) of IO3 and IO2 input voltage signal, (speed equals distance between two light-sensitive elements divided by the time difference also can to draw the speed of light beam translational speed, so be inversely proportional to the time difference, be the inverse of time difference), and with this parameter as the adjustment motor speed, make the rate of climb be subjected to the control of light beam translational speed, namely be when light beam moves up fast, motor speed improves fast, the aircraft fast rise, when light beam slowly moved up, motor speed slowly improved, aircraft slowly upwards rises, and realizes the remote control with analog quantity.When light beam is from up to down when inswept G2, G3, then duty is opposite, thereby the result makes aircraft main screw decelerating through motor that aircraft is descended, and can realize equally the control with analog quantity.For fear of misoperation, preferably set a sense cycle, when light-sensitive element G2 and arbitrary of G3 received light beam irradiates first, sense cycle was beginning, only in sense cycle, detect the another light-sensitive element and also receive light beam irradiates, just make effective identification.After the sense cycle, circuit reenters original state.Sense cycle can be made as 0.1 to 1 second.This recognition technology is along with the direct reaction of sweeping of remote control light beam, and reaction speed is fast.This recognition technology is more suitable in the cylindricality light beam.
The thinking that relatively goes against the established rules of the second recognition technology, under the prerequisite that the light-sensitive element of the same sensitive surface diverse location of aircraft side is shone by the remote control light beam simultaneously, the precedence that control circuit breaks away from the remote control light beam irradiates according to the light-sensitive element of diverse location is identified the moving direction of remote control light beam.Specifically, the operator at first shines the covering of remote control light beam on the aircraft fuselage, makes G2 and G3 simultaneously by the full irradiation of light beam institute, at this moment the input IO2 of single-chip microprocessor MCU 2 and IO3 while high input voltage signal.Then the remote control light beam is moved up and down from aircraft fuselage, identify the moving direction of light beam according to the precedence of G2, G3 disengaging light beam irradiates.Be radiated on G2 and the G3 such as first light beam being covered, then upwards brandish light beam, then G3 breaks away from first the irradiation of light beam than G2, IO3 loses first high voltage signal than IO2, so it is bottom-up movement that MCU2 identifies light beam with this, the output of control circuit drives lifting executing agency, heightens the rotating speed of the main screw motor of aircraft, thereby aircraft is risen.Equally, successively lose the length of the time difference of high voltage signal according to IO3 and IO2, can draw the speed of light beam translational speed, and with this as the parameter of adjusting motor speed, make the rate of climb be subjected to the control of light beam translational speed, realize the remote control with analog quantity.When light beam is to brandish downwards when leaving toy, G2 breaks away from first light beam irradiates than G3, and then duty is opposite, thereby the result makes aircraft main screw decelerating through motor that aircraft is descended, and can realize equally the control with analog quantity.
This recognition technology is fit to have the cone-shaped beam of larger irradiated area, at first need during operation light beam covered and be radiated at it the toy machine, cumbersome, but advantage is light beam just has unglazed photograph in the movement of a direction, move up, move down, entirely shine totally four kinds of states, controls more flexible and changeable.Particularly G2 and G3 are simultaneously by light beam irradiates and the not mobile full irradiating state of light beam, can make toy keep a kind of intermediateness, such as making aircraft keep unsettled stop, (be that the lift that screw produces just equals gravity, it is unsettled that aircraft aloft keeps), when light beam moves down, then aircraft descends; When light beam moves up, then aircraft rises; Not having light beam irradiates then to be identified as does not have new remote control intention, keeps original rising, decline or vacant state; And if in process of rising or falling, entirely shone by light beam again, then enter again vacant state.Be more cleverly: in by the vacant state of the full irradiation of light beam, if because other factor aircraft break away from the light beam irradiates scope, such as being fallen downwards by interference in air flow, when G3 below breaks away from light beam, control circuit can be identified as light beam by mistake and move up, so drive lifting executing agency aircraft is risen, until G3 comes back to the light beam irradiates scope; On the contrary, when aircraft upwards breaks away from the light beam irradiates scope, such as inertia to upper punch, when superincumbent G2 breaks away from light beam, control circuit can be identified as light beam by mistake and move down, so drive execution unit aircraft is descended, until G2 comes back to the light beam irradiates scope, so that aircraft similarly is to be trapped in the cone-shaped beam the inside, be called trap state, very ingenious, object for appreciation is got up also more interesting, is the preferred a kind of recognition technology of the present invention.
Above-mentioned remote control light beam is the recognition technology that the vertical direction Y-axis moves up and down at above-below direction, can satisfy the straighforward operation of the aircraft that only has rising and down maneuver.For also with left/right rotation to executing agency, namely realize the action control of aircraft left/right rotation by steer motor or electromagnetic mechanism, (such as toy helicopter just can by arrange the tail motor cooperate horizontal tail-rotor realize left/right rotation to, also can aircraft center of gravity is offset or realize turning to by the inclination angle that electromagnetic mechanism produces to the left and right main screw by electromagnetic mechanism, this is prior art), the present invention can by the remote control light beam the move left and right of left and right directions (horizontal direction, i.e. X-axis) realize left/right rotation to remote control.Such as Fig. 2, on the aircraft 4 fuselage sides, two positions also are provided with two light-sensitive element G4 and G5 about same sensitive surface, consist of the light beam receiving circuit with resistance R 4, R5 respectively, and its output is connected to input IO4 and the IO5 of MCU2.MCU2 identifies the moving direction of remote control light beam on left and right directions according to the voltage change of IO4 and IO5, another road output of control circuit is turned left or is turned right by turning to executing agency to control aircraft, such as Fig. 3, it is the same that its operation principle is stated above-below direction with the recognition methods front.Cause turning to excessive for fear of long in time not closing of go to action time of implementation, control circuit can be provided with the automatic delay function function, during each startup go to action, only carry out a bit of time, (according to different steering mechanism should the time generally several seconds to several seconds zero point), then autoshutdown is until receive the remote information that turns to next time.
The recognition technology of the embodiment of Fig. 2 and Fig. 3 all is to carry out work with two light-sensitive elements, this is the minimum number of identification light beam moving direction, if increase the quantity of light-sensitive element, obviously also can according to the identification of same principle realization to the light beam moving direction, just increase material.
For also with the executing agency that advances, the action control of namely realizing that by advance motor or electromagnetic mechanism aircraft advances or retreats, (such as some toy helicopter special motor is set just and cooperates longitudinally the tail-rotor action that realizes moving forward and backward, some then is to make main screw produce an inclination angle by electromagnetic mechanism to realize this function, this belongs to prior art), then the present invention also can realize remote control by the identification to " light source approaches the movement of toy " and " light source leaves the movement of toy ", forward and backward these two kinds mobile variations that namely (also are direction of advance, are equivalent to Z axis) on the rectilinear direction of remote controller and toy by the remote control light beam are transmitted telecommand.Scheme is: at aircraft fuselage light-sensitive element is set and comes receiving beam, control circuit is identified the variation of beam intensity by the variation of the signal strength signal intensity of light-sensitive element, and then identifies the moving direction of light beam.When beam intensity becomes large, be identified as beam light source and approaching toy, when beam intensity diminishes, be identified as beam light source and leaving toy, realize the remote control of two kinds of instructions with this.This mode relatively is suitable for cone-shaped beam.
Realize a kind of circuit such as Fig. 4 of such scheme.Be arranged on the light-sensitive element G1 on the fuselage side of aircraft, consist of the light beam receiving circuit with resistance R 1, its output is connected to an input port IO1 with modulus (A/D) translation function of the single-chip microprocessor MCU 1 of control circuit, and when not having light beam irradiates to arrive G1, the dark resistance of G1 is very large, be output as very low voltage, when light beam irradiates arrives G1, the G1 resistance decreasing, it is large that output voltage becomes, luminous intensity is larger, and then output voltage is higher.MCU1 constantly detects and reads the IO1 voltage value, and the numerical value of front and back is compared, and judges the situation of the moving direction of light beam, and the output of control circuit is controlled advancing of aircraft by the executing agency that advances or retreated.MCU1 can adopt the various single-chip microcomputers with analog-digital conversion function, such as PIC16FXX series.
Concrete operation and identifying are: 1, when the operator with the remote control light beam irradiates to aircraft, but keeping remote controller static is that light beam is not mobile, at this moment light-sensitive element G1 receives the constant remote control light beam of intensity, the voltage of IO1 is higher (to be higher than the setting threshold values, this threshold values is slightly larger than the output valve of light beam receiving circuit under the ambient light), but voltage value remains unchanged (changing value is very little), then identify remote control and be intended to static, make aircraft keep static stop state so the output of control circuit drives the executing agency that advances.2, when the operator with the remote control light beam irradiates to aircraft, and to make remote controller flyby device namely be that beam light source is moved forward towards the aircraft direction, at this moment light-sensitive element G1 receives the constantly large remote control light beam of change of intensity, the voltage of IO1 is higher and becoming large, then identify remote control and be intended to advance forward, so control circuit output advances forward aircraft by the executing agency that advances.And can become large rate of change according to voltage, obtain the signal of light beam translational speed, thereby the operating power of controlling motor is controlled the speed that aircraft advances, when beam intensity become large must be faster, then pace is faster, otherwise then slower, realizes the control with analog quantity.3, when the operator with the remote control light beam irradiates to aircraft, and to make remote controller namely be to make beam light source mobile backward along the aircraft direction away from aircraft, at this moment light-sensitive element G1 receives the remote control light beam that intensity constantly diminishes, the voltage of IO1 is higher but constantly diminishing, then identify remote control and be intended to retreat, so the output of control circuit draws back aircraft by the executing agency that advances.Can obtain the signal of light beam translational speed according to the rate of change of voltage decreases equally, thereby control the speed that the operating power control aircraft of motor retreats, when beam intensity diminishes sooner, then astern speed is faster, otherwise then slower.4, as the operator with the remote control light beam irradiates to aircraft, at this moment light-sensitive element does not receive light beam, the voltage of IO1 less (less than setting threshold values) then is identified as without new remote control intention, so the output of control circuit makes aircraft keep original motion state.(motion state originally comprise stop, advancing or retreat).If brandish in other words light beam aircraft is advanced, even close afterwards light beam, aircraft still keeps original forward travel state, until light beam is again shone aircraft and keeps motionless, aircraft is stopped.The action that some aerobat toy does not retreat is only advanced or is stopped, and its action that retreats also is equivalent to halted state.
The present invention is in order to narrate the convenience of operation principle, with the independently separately narration of embodiment of Fig. 4.In actual the use, the embodiment of Fig. 4 also can combine with Fig. 2 and Fig. 3.Light-sensitive element G1 can be arranged on same sensitive surface with G2-G5, in addition also can utilize G2-G5 wherein one come compatiblely as G1, MCU1 and MCU2 can adopt same single-chip microcomputer, just use different input and output sides.(single-chip microcomputer generally has abundant input and output terminal).
In addition, the aerobat toy of some low side (such as the driven helicopter of individual layer screw) fuselage when work is understood unstable and is spinned, at this moment also can all be provided with two light-sensitive elements at the above-below direction of a plurality of sides of aircraft fuselage (such as on four sides), G2 such as Fig. 3, G3 is the same, again with each top light-sensitive element parallel connection as a light-sensitive element (being the G2 of Fig. 3) place in circuit, with each following light-sensitive element parallel connection as a light-sensitive element (being the G3 of Fig. 3) place in circuit, be used for receiving the light beam that the Y-axis above-below direction moves in each side, so that can both effectively receive rising and the decline of remote control light beam and identification control aircraft in each side.(light resistance and the dark resistance of light-sensitive element differ greatly, and general direct parallel connection can work, the resistance of in case of necessity capable of regulating series connection).And to be used for that the control aircraft advances and left/right rotation to the identification of light beam, then only be arranged at an aircraft side backward, namely only advance at the back of aircraft remotely-piloted vehicle, stop with left/right rotation to.
Remote controller also can include modulation circuit, makes the remote control light beam band of its emission be useful on jamproof modulation intelligence.Come modulated beam of light such as adopting oscillating circuit to produce high frequency waves, perhaps adopt coding circuit to produce coded message and come modulated beam of light.Correspondingly on electronic toy with the demodulator circuit that modulation intelligence is carried out demodulation.This belongs to the conventional means of remote control.But it is not to carry remote information that light beam of the present invention adopts the purpose of modulation intelligence, but: 1, better improve anti-interference, avoid the interference of ambient light; 2, different remote control light beams can not interfered with each other each other.
For the object of the invention, the invention discloses multiple concrete technical scheme, multiple different remote control light beam is particularly disclosed, with the multiple recognition technology that on aircraft, the remote control light beam is moved, in actual applications, these different technologies schemes can be mixed use, and collocation is so that remote control is more flexible and changeable mutually.
As a kind of special case: same remote controller of the present invention is provided with two luminous tubes can launching different remote control light beams.Launch a kind of remote control light beam by a luminous tube job at ordinary times, launching another kind of light beam by the work of switching over another luminous tube when needed.The LED torch of transformation beam color (just have on the market can).These light beams are infrared beam, red visible light beam, green visible light beam, purple visible light beam, with the infrared beam of modulation intelligence, with wherein different two kinds of the visible light beam of modulation intelligence.Correspondingly adopt different light-sensitive element and optical filters to come cooperating at aircraft.This technology can be used for different aircraft are carried out remote control, has to be with two functions; Also be used in same aircraft, for the remote control of different directions, adopt red beam to come remote control such as above-below direction, left and right directions adopts green beam to come remote control, and that avoids that the remote control of different directions may occur once in a while interferes with each other, and improves the unfailing performance of work.
