Description
Technical field
The present invention relates to a kind of toy, be specially a kind of electric toy car with remote control.
Background technology
Remote-control electric minicar includes various forms of vehicle moulding, but its composition is basic the same, comprises remote controller and toy car, adopts radio or infrared remote control.Wherein remote controller comprises operation push-button or action bars, coding circuit and radiating circuit, and operator's both hands operate at remote controller, forms coded message by coding circuit and launches by radiating circuit.Toy car includes battery, control circuit and is used for driving the executing agency that vehicle is finished exercises, and control circuit comprises receiving circuit, decoding circuit and drive circuit.Receiving circuit receives remote controller and transmits, and decoding draws remote information through decoding circuit, and driving execution unit by drive circuit is that remote control actions is finished in electric motor car, as advance, retreat, accelerate, stop, left-hand rotation, right-hand rotation etc.
Existing remote controlled electric car, shortcoming when carrying out straighforward operation is the motion state that is representing toy car with some buttons of remote controller or action bars, the operator need to note the motion state of toy car on one side, button or the action bars of remote controller in bimanualness on one side, very not directly perceived, also increase operation easier, particularly for the less children of age, usually be difficult to well carry out straighforward operation.Because button or the action bars of remote controller have machine structural parts, cause volume and weight all larger, also easily damage.
Prior art also has a class by light beam irradiates different specific light photosensitive elements on toy is controlled different actions, such as Chinese patent 96249104.7 and 2010101096431, but this needs certain accuracy, for the continuous toy car that changes of motion state, a little a bit distance just is difficult to accomplish, and operation uses same intuitively and convenient, flexible not, and the remote control actions that can realize is also abundant not.
And above-mentioned telecontrol engineering, the remote information that generally can only send the switching value of several passages (namely only has 1 or 0 state, can only be state control, as advance or retreat), if transmission is with the remote information (information that namely has different controlled quentity controlled variables of analog quantity, such as advancing with friction speed or retreating), then need the adoption rate telecontrol engineering, remote controller also needs to use the action bars with potentiometer, circuit and structure are more complicated, operation easier is also higher, so the general remote control of all not adopting with analog quantity on common remote-control toy.
Summary of the invention
The present invention seeks to disclose a kind of straighforward operation easier remote-control electric minicar more directly perceived, further, this toy car can also be with the same remote control that realizes with analog quantity that is easy to operate directly perceived.
The present invention includes and comprise remote controller and toy car, toy car includes the executing agency that carries out remote control actions for driving toy car, it is characterized in that: remote controller includes luminous tube, is used for emission and can shines remote control light beam toy car, that can move at the toy car vehicle body; Toy car 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, such as the LED flashlight.
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 toy car of remote control light beam.Comprise move down, up mobile, toward move left, toward move right, light source (being the remote controller luminous tube) approaches the movement of toy car and the movement that light source leaves toy car.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 move forward and backward remote control of (or stopping) of toy car, at first toy car executing agency includes the executing agency of advancing that moves forward and backward for driving toy car, the diverse location of the above-below direction (be vertical direction, be equivalent to the Y-axis of coordinate system) of the present invention on the same sensitive surface of toy car vehicle body 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 variation of light-sensitive element input signal 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 the executing agency of advancing, and does corresponding action by the executing agency's driving toy car of advancing.The sensitive surface that light-sensitive element is set can be selected the trailing flank of vehicle body; Also can select the end face of vehicle body, above-below direction at this moment that is to say the fore-and-aft direction of vehicle body end face.
For the remote control that realizes that toy car turns left and turns right, at first toy car executing agency include for drive the toy car 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 of toy car vehicle body 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 variation of light-sensitive element input signal 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 go to action by turning to executing agency to drive toy car.
For realizing the move forward and backward remote control of (or halting) of toy car, also can adopt another kind of scheme: control circuit is according to the variation of the input signal strength of the same light-sensitive element that arranges on the toy car vehicle body, identify the moving direction of remote control light beam on the rectilinear direction (being equivalent to Z axis) of remote controller and toy car, comprise that light source approaches the movement of toy car, or light source leaves the movement of toy car; The output of control circuit is connected to the executing agency of advancing, and does corresponding action by the executing agency's driving toy car of advancing, and namely advances, retreats (or halting).
The present invention is suitable for remote-controlled toy vehicle 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 the toy car vehicle body, the control circuit of toy car 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 toy car.Carry out a kind of concrete straighforward operation such as adopting above-mentioned technology: the remote control light beam is covered the sensitive surface (so that light-sensitive element all receives light beam simultaneously) that shines toy car and when not moving, the toy car stop motion keeps armed state; (refer to that sensitive surface is arranged on the situation of vehicle body rear side, if sensitive surface is arranged on the vehicle body end face, then be equivalent to from back to front inswept toy car end face of light beam) during with the bottom-up inswept toy car vehicle body of remote control light beam, the executing agency of advancing starts advances toy car; With the remote control light beam from up to down during inswept toy car vehicle body (if sensitive surface is arranged on the vehicle body end face, then be equivalent to light beam from going to rear inswept toy car end face), the executing agency of advancing makes toy car retreat (toy car for there not being fallback state then halts); When the inswept toy car in the remote control light beam left and right sides, the executing agency's action that turns to of toy car turns left toy car or right-hand rotation; Then toy car does not keep original motion state when having light beam irradiates.
The present invention with traditional remote-controlled toy 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 toy car, make the remote control light beam mobile to the different directions generation on toy car but brandish remote controller according to remote control intention one hand, realize remote control to toy car 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, work more reliable, 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 toy car.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 the infrared beam interference free performance better, but cannot see the remote control light beam, have some difficulty, 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 brandish just can remote-control toy, more have strange sensation and interest.When the remote control light beam adopted visible light beam, for fear of the interference of ambient light, light beam should not adopt white light, adopts 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 the light-sensitive element front of toy car.Adopt colored light beam can improve anti-interference.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 toy car identifies direction and speed that the remote control light beam moves by the variation of the input signal of light-sensitive element; And according to the 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 variation of the light-sensitive element input signal 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 of the Strength Changes of the input signal by same light-sensitive element, identify the translational speed of remote control light beam, be applicable to toy car and remote controller and move at the light beam of rectilinear direction (being Z axis).This improvement makes toy car can brandish according to the operator speed speed of remote controller light beam, control the speed of execution action, make the light beam inswept toy car that makes progress fast such as upwards brandishing fast remote controller, then toy car advances fast, upwards slowly brandish remote controller and make the light beam inswept toy car that slowly makes progress, then toy car worms, and realizes 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 toy, 3 grades (namely fast, neutralization slowly) are set, and can meet the demands.This improves with simple method, realizes the remote control to toy car 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 and more intuitively is easy to remote-controlled toy vehicle, and for realizing correlation technique of the present invention, executing agency such as toy car, drive toy car by motor cooperative mechanical mechanism and carry out the action of advancing, retreat, stop, turning left, turn right, belong to existing toy technique.The control circuit of toy car of the present invention except including the identification circuit for identification light beam moving direction or speed, generally also includes the control signal of identification circuit output is carried out power amplification for use in the drive circuit that drives executing agency's action.And some basic functions of circuit involved in the present invention, comprise the reception of light and the detection of intensity, modulus (A/D) conversion and computing to voltage signal are compared, by adjusting operating voltage or PWM pulsewidth modulation to the control of power of motor and rotating speed, thereby the movement velocity of control toy car, also comprise how adopting single-chip microprocessor MCU or DSP or other circuit according to operation principle of the present invention and logic is designed various physical circuits 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 toy car 2, the a branch of remote control light beam 3 that can shine toy car 2 of operator's single-hand handling ﹠ remote controller 1 emission during use, and brandish remote controller according to remote control intention, remote control light beam 3 is produced mobile at the toy car vehicle body, or claim to sweep, brandish; Toy car 2 is by the light-sensitive element receiving beam 3 on the vehicle body, and the electronic circuit of toy car identifies the moving direction of remote control light beam, controls the action of toy car 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 on the toy car vehicle body, and handled easily can adopt or the various compact LED flashlights with optically focused of reference.
Toy car 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 toy car vehicle body, can be the trailing flank of vehicle body, and the perhaps end face of vehicle body is so that easilier during work shone 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 beam, and 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, and 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 remote control intention and toy car is controlled with this, the below is described in detail this.
For the remote control that realizes that toy car moves forward and backward, at first toy car executing agency includes the executing agency of advancing, and namely drives toy car by the driven by motor wheel and does the action that moves forward and backward; The scheme that the present invention adopts is: the diverse location of the above-below direction on the same sensitive surface of toy car vehicle body (being vertical direction, also is Y-axis) is provided with two light-sensitive elements that are used for receiving the 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 input signal variation of light-sensitive element on the diverse location, identifies the remote control intention with this, and controls the executing agency of advancing and do corresponding action.Embodiment such as Fig. 2, on the end face of toy car 4 vehicle bodies, be respectively arranged with light-sensitive element G2 and G3 in two positions of above-below direction (when toy car kept flat, the above-below direction of Fig. 2 also was fore-and-aft direction), receive mobile change of remote control light beam on above-below direction.The circuit of toy car 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 the executing agency of advancing, drive the toy car execution by the executing agency of advancing and advance or backward movement.MCU2 does not have specific (special) requirements, can adopt various general single chips.
Control circuit is to the identification of remote control light beam moving direction, and the present invention discloses following two kinds of 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 toy car, 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 subjected 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, also namely the at this moment IO2 of MCU2 and IO3 input is low voltage signal all, as original state.Then when the remote control 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 becomes very little when being 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 identified light beam afterwards with the elder generation of high input voltage pulse, the output of control circuit drives the executing agency of advancing, and drives toy car and advances forward.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 pace be subjected to the control of light beam translational speed, namely be when light beam moves up fast, motor speed improves fast, toy car advances fast, and when light beam slowly moved up, motor speed slowly improved, toy car worms, and realizes the remote control with analog quantity.When light beam is from up to down when inswept G2, G3, then duty is opposite, and the result makes the executing agency of advancing drive toy car to retreat, and can realize the control with analog quantity equally.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.
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 toy car 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 toy car vehicle body, 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 the toy car vehicle body, 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 executing agency of advancing is controlled in the output of control circuit, drives toy car and advances.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 pace 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 car, G2 breaks away from first light beam irradiates than G3, and then duty is opposite, and the result retreats toy car, and can realize the control with analog quantity equally.
This recognition technology is fit to have the cone-shaped beam of larger irradiated area, at first need during operation light beam covered and entirely be radiated at it the toy car, cumbersome, advantage is that light beam just has unglazed photograph in the movement of a direction, moves up, moves down, entirely shines totally four kinds of states, controls more flexible and changeable.Particularly G2 and G3 simultaneously by light beam irradiates and the not mobile full irradiating state of light beam, can make toy car remain on out-of-work dead ship condition, and when light beam moves up, then toy car advances; When light beam moves down, then toy car retreats; Not having light beam irradiates then to be identified as does not have new remote control intention, continues to keep original and advances, retreats or dead ship condition; And if advance or fallback procedures in entirely shone by light beam again, then enter again dead ship condition.Be more cleverly: in by the dead ship condition of the full irradiation of light beam, if because other factor toy cars break away from the light beam irradiates scope, such as going out forward the light beam irradiates scope owing to inertia, when superincumbent G2 breaks away from light beam irradiates, control circuit can be identified as light beam by mistake and move down, so drive the executing agency of advancing toy car is retreated, until G2 comes back to the light beam irradiates scope; On the contrary, when toy car inertia breaks away from the light beam irradiates scope to backlash, when G3 below broke away from light beam, control circuit can be identified as light beam by mistake and move up, so drive execution unit toy car was advanced, until G3 comes back to the light beam irradiates scope; So that toy car 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 identification control technology that the vertical direction Y-axis moves up and down at above-below direction, can satisfy the straighforward operation of the toy car that only has the action of moving forward and backward.And for also with left/right rotation to executing agency, namely drive the action control that toy car turns left or turns right by technology such as steer motor or electromagnetic mechanisms (electromagnetic steering engine), then the present invention can by the remote control light beam the move left and right of left and right directions (be horizontal direction, i.e. X-axis) realize left/right rotation to remote control.Such as Fig. 2, on the fuselage of toy car 4, 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 drive toy car, such as Fig. 3, its operation principle and recognition technology, it is the same following the identification of above-below direction.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.
The remote control that moves forward and backward for toy car, the present invention also can realize remote control by the identification to " light source approaches the movement of toy car " and " light source leaves the movement of toy car ", and forward and backward these two kinds mobile variations that namely (are equivalent to the reference axis Z axis) by the remote control light beam on the rectilinear direction of remote controller and toy car are transmitted telecommand.Concrete scheme is: be provided with light-sensitive element at the toy car vehicle body and receive the remote control light beam, control circuit is identified the variation of beam intensity by the variation of the input signal strength 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 car, when beam intensity diminishes, be identified as beam light source leaving toy car, realize remote control 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 toy car vehicle body, 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 drives advancing of toy car by the executing agency of advancing or retreats.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 toy car, 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, executing agency makes toy car keep dead ship condition so the output of control circuit control is advanced.2, when the operator with the remote control light beam irradiates to toy car, and to make remote controller approach toy car namely be that beam light source is moved forward towards the toy car 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, advance forward so the output of control circuit drives toy car by the executing agency of advancing.And according to the large rate of change of light-sensitive element input voltage signal change, can obtain the signal of light beam translational speed, thereby the speed that the operating power control toy car of controlling motor advances, when becoming, beam intensity becomes greatly faster, then pace is faster, otherwise then slower, realize the control with analog quantity.3, when the operator with the remote control light beam irradiates to toy car, and to make remote controller namely be to make beam light source mobile backward along the toy car direction away from toy car, 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 toy car by the executing agency of advancing.The rate of change that can diminish according to the light-sensitive element input voltage signal equally, obtain the signal of light beam translational speed, thereby the operating power of controlling motor is controlled the speed that toy car retreats, when beam intensity diminishes sooner, then astern speed is faster, otherwise then slower.4, as the operator not with the remote control light beam irradiates to toy car, 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, and the output of control circuit makes toy car keep original motion state.(motion state originally comprise advance, retreat or stop).If mobile beam advances toy car in other words, even close afterwards light beam, toy car still keeps original forward travel state, until light beam is again shone toy car and keeps motionless, toy car is stopped.The action that some toy car does not retreat is only advanced or is stopped, and the action that then retreats can only be implemented as dead ship condition.
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 G4 and G5, adopts same single-chip microcomputer, and G1 is used for the remote control that identification realizes that toy car moves forward and backward, G4 and G5 be used for identification realize left/right rotation to remote control.Even also can utilize wherein light-sensitive element of G4 and G5 next compatible as G1, because both recognition technologies are different, can accomplish to carry out work according to different recognition technologies with controlling in identification.
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 toy car with the demodulator circuit that modulation intelligence is carried out demodulation.This belongs to the conventional means of remote control.But remote control light beam of the present invention is not to carry remote information with 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.
Remote controller of the present invention also can be 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.Adopt corresponding light-sensitive element and optical filter to come cooperating at toy car.This technology can be used for different toy cars are carried out remote control, has to be with two functions; Also be used in same toy car, for the remote control of different directions, adopt red beam to come remote control such as the forward-reverse direction, left/right rotation is to adopting green beam to come remote control, 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.
