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 launch by radiating circuit by coding circuit.Toy car includes battery, control circuit and the executing agency for driving vehicle to complete exercises, and control circuit comprises receiving circuit, decoding circuit and drive circuit.Receiving circuit receives remote controller and transmits, and draws remote information through decoding circuit decoding, and driving execution unit by drive circuit is that electric motor car completes remote control actions, as advance, retreat, accelerate, stop, left-hand rotation, right-hand rotation etc.
Existing remote controlled electric car, shortcoming while carrying out straighforward operation is the motion state that is representing toy car with some buttons of remote controller or action bars, 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, be usually 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 to different actions, as Chinese patent 96249104.7 and 2010101096431, but this needs certain accuracy, the toy car constantly changing for motion state, a little a little distance is just difficult to accomplish, and operation uses same intuitively and convenient, flexible not, 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 (only has 1 or 0 state, can only be state control, as advance or retreat), if the remote information sending with analog quantity (has the information of different controlled quentity controlled variables, such as advancing with friction speed or retreating), need 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 generally all do not adopt the remote control with analog quantity on common remote-control toy.
Summary of the invention
The present invention seeks to open 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 realizing with analog quantity that is easy to operate directly perceived.
The present invention includes and comprise remote controller and toy car, toy car includes for driving toy car to carry out the executing agency of remote control actions, it is characterized in that: remote controller includes luminous tube, can be irradiated to remote control light beam toy car, that can move for launching on toy car vehicle body; Toy car includes the light-sensitive element for receiving remote control light beam; With for identifying the moving direction of remote control light beam according to light-sensitive element input signal and controlling the control circuit of executing agency according to remote control light beam moving direction; Light-sensitive element is connected to control circuit input; The output of control circuit is connected to executing agency.(in present specification, remote control light beam is sometimes also referred to as light beam).
The remote control light beam of described remote controller transmitting, is cylindricality light beam, or cone-shaped beam.These light beams adopt luminous tube electrified light emitting to produce optically focused through concentration structure again and form, and this belongs to electrooptics aspect common technology, as LED flashlight.
The movement of described remote control light beam, or claim to sweep, brandish, be the movement towards space different directions on the same sensitive surface of toy car of remote control light beam.Comprise move down, up move, toward moving left, toward moving right, movement that light source (being remote controller luminous tube) approaches toy car and light source leave the movement of toy car.Remote control light beam is to mobile corresponding the specific remote information of each direction.Same sensitive surface is a face that can simultaneously be subject to remote control light beam irradiates.
For the move forward and backward remote control of (or stopping) of toy car, first toy car executing agency includes the executing agency of advancing for driving toy car to move forward and backward, 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 at least provided with two for receiving the light-sensitive element of remote control light beam; Control circuit is according to the precedence of the variation of light-sensitive element input signal on diverse location, identify the moving direction of remote control light beam on above-below direction, be that light beam moves down or up moves, identify remote control intention with this, the output of control circuit is connected to the executing agency of advancing, and drives toy car to do corresponding action by the executing agency of advancing.The sensitive surface that light-sensitive element is set can be selected the trailing flank of vehicle body; Also the end face that can select vehicle body, above-below direction at this moment that is to say the fore-and-aft direction of vehicle body end face.
For realizing, toy car turns left and the remote control of right-hand rotation, first toy car executing agency includes the executing agency that turns to for driving toy car left and right turn, the diverse location of the left and right directions (be also horizontal direction, i.e. X-axis) of the present invention on the same sensitive surface of toy car vehicle body is at least provided with two for receiving the light-sensitive element of remote control light beam; Control circuit is according to the precedence of the variation of light-sensitive element input signal on 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 by turning to executing agency to drive toy car to do corresponding go to action.
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 arranging on toy car vehicle body, identify the moving direction of remote control light beam in 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 drives toy car to do corresponding action by the executing agency of advancing, and advances, retreats (or halting).
The present invention is suitable for the remote control of remote-controlled toy vehicle in indoor or outdoors closer distance.When use, operator's hand-held remote controller sends remote control light beam, brandishing remote controller according to remote control intention makes remote control light beam irradiates also produce and move to toy car vehicle body, the control circuit of toy car receives remote control light beam by light-sensitive element, identify its moving direction, also identify operator's remote control intention, and drive toy car to make corresponding actions by executing agency.Carry out a kind of concrete straighforward operation such as adopting above-mentioned technology: remote control light beam is covered and is irradiated to the sensitive surface (make light-sensitive element all receive light beam) of toy car and while not moving, toy car stop motion keeps armed state simultaneously; During by bottom-up remote control light beam inswept toy car vehicle body, (refer to that sensitive surface is arranged on the situation of vehicle body rear side, if sensitive surface is arranged on vehicle body end face, be equivalent to light beam inswept toy car end face from back to front), the executing agency of advancing starts advances toy car; By remote control light beam from up to down when inswept toy car vehicle body (if sensitive surface is arranged on vehicle body end face, be equivalent to light beam from going to rear inswept toy car end face), the executing agency of advancing makes toy car retreat (for the toy car that there is no fallback state, halting); In the time of the inswept toy car in remote control light beam left and right, the executing agency's action that turns to of toy car turns left toy car or turns right; In the time there is no light beam irradiates, toy car keeps original motion state.
The present invention is with traditional remote-controlled toy vehicle comparison, the advantage having is: 1, operator is without button or the action bars of bimanualness remote controller, also without accurately aiming at different light-sensitive element on toy car, make remote control light beam produce and move to different directions on toy car but brandish remote controller according to remote control intention one hand, to move intuitively to realize the remote control to toy car, so straighforward operation is extremely directly perceived and easily simple, is especially applicable to the children that age is little and uses; 2, remote controller is just launched remote control light beam, remote information is not included in light beam the inside, but transmitted by the moving direction of light beam, so circuit is extremely simple, be exactly that power drives luminous tube is luminous, do not need button and action bars, work more reliable, and remote controller profile can do very little very flexibly, such as making elongated remote control rod, baton, conjury stick, make the richer interest of toy remote control.
The remote control light beam of remote controller transmitting, can be visible light beam or infrared beam, or comprise both beam combinations simultaneously.Its operation principle is the same, different just luminous tubes, and supporting light-sensitive element on toy car.In fact a lot of light-sensitive elements can be suitable for visible ray and infrared ray simultaneously, just the filter difference before light-sensitive element.Adopt visible light beam can see remote control light beam, operate control more directly perceived and easier, be applicable to children's use that various crowds comprise little age; Use infrared beam interference free performance better, but cannot see remote control light beam, there is some difficulty, if be also straightline propagation but operator understands infrared ray, just can be with feeling to hold the movement of controlling light beam, and cannot see light beam while using, only see that arm or remote control rod, brandish just can remote-control toy, more have strange sensation and interest.In the time that remote control light beam adopts 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 before the light-sensitive element of toy car, be added with redness or optical filter green or blue or purple.Adopt colored light beam can improve anti-interference.Also can launch infrared beam and transmit remote control intention, launch visible light beam simultaneously and supply operator's reference location, and make both optically focused become same beam combination together, reach existing anti-interference easy-operating advantage directly perceived again.
As further improvement, the control circuit of toy car, by the variation of the input signal of light-sensitive element, identifies direction and speed that remote control light beam moves; And the speed moving according to remote control light beam, 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 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 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 operator the speed speed of remote controller light beam, control the speed performing an action, make light beam inswept toy car upwards fast such as upwards brandishing fast remote controller, toy car advances fast, upwards slowly brandish remote controller and make slowly inswept toy car upwards of light beam, toy car worms, and realizes the remote control with analog quantity.According to the requirement to different toy controls, can different progression be set to the quantification of this analog quantity, as tens grades, in general, to the responsiveness of most toy, 3 grades (fast, neutralization slow) are set, can meet the demands.This improvement is with simple method, realizes the remote control to toy car band analog quantity, makes distant control function more powerful abundanter, and remote controller is without adopting complicated band potentiometer action bars, and also, without increasing circuit, straighforward operation is simple, intuitive especially, more joyful.

detailed description of the inventionbelow with reference to the accompanying drawings, to how implementing the present invention describe.
It should be noted that, the object of the invention is that open a kind of operation is more intuitively easy to remote-controlled toy vehicle, and for realizing correlation technique of the present invention, such as the executing agency of toy car, drive toy car to carry out the action of advancing, retreat, stop, turning left, turn right by motor cooperative mechanical mechanism, belong to existing toy technique.The control circuit of toy car of the present invention, except including the identification circuit for identifying light beam moving direction or speed, generally also includes the control signal of identification circuit output is carried out to 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 reception to light and the detection of intensity, modulus (A/D) conversion and computing comparison to voltage signal, by adjusting operating voltage or the control of PWM pulsewidth modulation to power of motor and rotating speed, thereby control the movement velocity of 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, all belong to the common technology of electronic technology field and toy remote control, the present invention does not describe in detail.And for simplicity, the circuit diagram of accompanying drawing of the present invention only draws the element relevant with operation principle, other circuit parts are as anti-interference in power supply, filtering, clock, reset, input, the interlock circuit such as power amplification and driving of output, belongs to general knowledge, does not also draw.
Fig. 1 is operation principle schematic diagram of the present invention.The present invention includes remote controller 1 and toy car 2, when use, operator's single-hand handling & remote controller 1 is launched a branch of remote control light beam 3 that can be irradiated to toy car 2, and brandish remote controller according to remote control intention, remote control light beam 3 is produced on toy car vehicle body mobile, or claim to sweep, brandish; Toy car 2 is by the light-sensitive element receiving beam 3 on 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 transmitting, 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 as luminous in LED again through optically focused formation light beam, belongs to conventional electrooptical technology.While adopting cylindricality light beam, light beam irradiated area is less, and light is concentrated, and can carry out longer-distance remote control, the laser pointer with low-power laser pipe that typically can adopt or commonly use with reference to multimedia teaching; What Fig. 1 adopted is cone-shaped beam, and the irradiated area of cone-shaped beam is larger, can more easily be irradiated on 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 for driving aircraft to carry out the executing agency of remote control actions.Light-sensitive element is arranged on toy car vehicle body, can be the trailing flank of vehicle body, or the end face of vehicle body, while making work, is more easily irradiated to by remote control light beam.Before light-sensitive element, be generally also added with the colour filter corresponding with remote control light beam, such as red beam just coordinates Red lightscreening plate, some light-sensitive element self is with optical filter.Light-sensitive element is according to the different conditions output different electrical signals of illumination and deliver to control circuit, and control circuit, according to the signal intensity of light-sensitive element, identifies the moving direction of light beam, identifies remote control intention with this, drives executing agency to carry 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, below this is described in detail.
For the remote control that realizes toy car and move forward and backward, first toy car executing agency includes the executing agency of advancing, the action that drives toy car to do to move forward and backward by driven by motor wheel; The scheme that the present invention adopts is: the diverse location of the above-below direction (being vertical direction, is also Y-axis) on the same sensitive surface of toy car vehicle body is at least provided with two for receiving the light-sensitive element of remote control light beam; The precedence that control circuit changes according to the input signal of light-sensitive element on diverse location, identifies the moving direction of remote control light beam on above-below direction, identifies remote control intention with this, and controls the executing agency of advancing and do corresponding action.An embodiment is 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 (in the time that toy car keeps flat, the above-below direction of Fig. 2 is also fore-and-aft direction), receive mobile change of remote control light beam on above-below direction.The circuit of toy car is as Fig. 3.Light-sensitive element G2, G3 respectively series resistance R2, R3 form 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 MCU2 control signal is carried out to power amplification, the output of drive circuit is as the output of control circuit, be connected to the executing agency of advancing, drive toy car to carry out by the executing agency of advancing and advance or backward movement.MCU2 does not have particular/special requirement, can adopt various general single chips.
The identification of control circuit to remote control light beam moving direction, the present invention discloses following two kinds of recognition technologies.
The first recognition technology is under the prerequisite not all being irradiated to by remote control light beam at the light-sensitive element of the same sensitive surface diverse location of toy car, and the precedence that control circuit receives remote control light beam irradiates according to the light-sensitive element of diverse location is identified the moving direction of remote control light beam.While beginning, G2 and G3 are not subject to light beam irradiates, and G2 and G3 dark resistance are very large, and with the very low voltage of output after electric resistance partial pressure, also at this moment the IO2 of MCU2 and IO3 input are all low voltage signal, as original state yet.Then when remote control light beam from 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, G3 and G2 successively receive of short duration light beam irradiates, in the time being subject to light beam irradiates, light resistance becomes very little, so IO3 and IO2 be 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 to advance forward.According to the length of the time difference of IO3 and IO2 input voltage signal (being also the time interval), also can show that (speed equals distance between two light-sensitive elements divided by the time difference for the speed of light beam translational speed, so be inversely proportional to the time difference, be the inverse of time difference), and using this as the parameter of adjusting motor speed, make pace be subject to the control of light beam translational speed, be in the time that light beam moves up fast, motor speed improves fast, toy car advances fast, in the time that light beam slowly moves up, motor speed slowly improves, toy car worms, the remote control of realization with analog quantity.When light beam is from up to down when inswept G2, G3, duty is contrary, and result is that the executing agency that makes to advance drives toy car to retreat, and can realize the control with analog quantity equally.For fear of misoperation, preferably set a sense cycle, in the time that light-sensitive element G2 and arbitrary of G3 first receive light beam irradiates, sense cycle is beginning, only in sense cycle, detect that another light-sensitive element also receives light beam irradiates, just make effective identification.After a 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 being irradiated to by remote control light beam at the light-sensitive element of the same sensitive surface diverse location of toy car, control circuit is identified the moving direction of remote control light beam according to the precedence of the light-sensitive element disengaging remote control light beam irradiates of diverse location simultaneously.Specifically, first operator covers remote control light beam to be irradiated on toy car vehicle body, and G2 and G3 are irradiated entirely by light beam simultaneously, at this moment the input IO2 of single-chip microprocessor MCU 2 and IO3 high input voltage signal simultaneously.Then remote control light beam is moved up and down from toy car vehicle body, identify the moving direction of light beam according to the precedence of G2, G3 disengaging light beam irradiates.Such as first light beam being covered and is radiated on G2 and G3, then upwards brandish light beam, G3 first departs from the irradiation of light beam than G2, IO3 first loses high voltage signal than IO2, so it is bottom-up movement that MCU2 identifies light beam with this, the output control of the control circuit executing agency of advancing, drives toy car to advance.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 using this as the parameter of adjusting motor speed, make pace be subject to the control of light beam translational speed, realize the remote control with analog quantity.When light beam is to brandish downwards while leaving toy car, G2 first departs from light beam irradiates than G3, and duty is contrary, and result is that toy car is retreated, and can realize the control with analog quantity equally.
This recognition technology is applicable to having the cone-shaped beam of larger irradiated area, when operation, first need light beam to cover and be entirely radiated at it toy car, cumbersome, advantage is that light beam just has unglazed photograph in the movement of a direction, moves up, moves down, entirely irradiates 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, toy car advances; When light beam moves down, toy car retreats; Not having light beam irradiates 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 irradiated by light beam again, enter again dead ship condition.More cleverly: in by the full dead ship condition irradiating of light beam, if because other factor toy cars depart from light beam irradiates scope, such as because inertia is gone out forward light beam irradiates scope, when superincumbent G2 departs from light beam irradiates, control circuit can be identified as light beam by mistake and move down, so drive the executing agency of advancing that toy car is retreated, until G2 comes back to light beam irradiates scope; On the contrary, when toy car inertia departs from light beam irradiates scope to backlash, when G3 below departs from light beam, control circuit can be identified as light beam by mistake and move up, then drive execution unit that toy car is advanced, until G3 comes back to light beam irradiates scope; Making toy car similarly is to be trapped in cone-shaped beam the inside, is called trap state, and 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 vertical direction Y-axis moves up and down at above-below direction, can meet the straighforward operation of the toy car only with the action of moving forward and backward.And for the action control that also with left and right turn executing agency, drives toy car to turn left or turn right by technology such as steer motor or electromagnetic mechanisms (electromagnetic steering engine), the present invention can the remote control that moves left and right to realize left and right turn left and right directions (being horizontal direction, i.e. X-axis) by remote control light beam.As Fig. 2, on the fuselage of toy car 4, position, two of left and right at same sensitive surface is also provided with two light-sensitive element G4 and G5, forms light beam receiving circuit respectively with resistance R 4, R5, 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, export by turning to executing agency drive toy car to turn left or turn right on another road of control circuit, as Fig. 3, its operation principle and recognition technology are the same with the identification of above-below direction.Cause turning to excessive for fear of long not closing in time of go to action time of implementation, control circuit can be provided with automatic delay function function, when each startup go to action, only carry out a bit of time, (according to this time of different steering mechanism generally several seconds to several seconds zero point), then automatically close, until receive the remote information turning to next time.
The recognition technology of the embodiment of Fig. 2 and Fig. 3 is all 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 realize the identification to light beam moving direction according to same principle, just increase material.
The remote control moving forward and backward for toy car, the present invention also can be by realizing remote control to the identification of " 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 (are equivalent to reference axis Z axis) by remote control light beam in the rectilinear direction of remote controller and toy car are transmitted telecommand.Concrete scheme is: be provided with light-sensitive element at toy car vehicle body and receive 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.In the time that beam intensity becomes large, be identified as beam light source and approaching toy car, in the time that beam intensity diminishes, be identified as beam light source leaving toy car, realize remote control with this.Which is relatively suitable for cone-shaped beam.
Realize a kind of circuit of such scheme as Fig. 4.Be arranged on the light-sensitive element G1 on toy car vehicle body, form light beam receiving circuit with resistance R 1, one of single-chip microprocessor MCU 1 that its output is connected to control circuit has the input port IO1 of modulus (A/D) translation function, and in the time not having light beam irradiates to arrive G1, the dark resistance of G1 is very large, be output as very low voltage, in the time that light beam irradiates arrives G1, G1 resistance decreasing, it is large that output voltage becomes, luminous intensity is larger, and output voltage is higher.MCU1 constantly detects and reads 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 driven advancing of toy car or retreated by the executing agency of advancing.MCU1 can adopt the various single-chip microcomputers with analog-digital conversion function, such as PIC16FXX series.
Concrete operation and identifying are: 1, when operator by remote control light beam irradiates to toy car, but keeping remote controller static is that light beam does not move, at this moment light-sensitive element G1 receives the constant remote control light beam of intensity, the voltage of IO1 is higher (higher than setting threshold values, this threshold values is slightly larger than the output valve of light beam receiving circuit under ambient light), but voltage value remains unchanged (changing value is very little), identify remote control and be intended to static, so the output control of control circuit is advanced, executing agency makes toy car keep dead ship condition.2, when operator by remote control light beam irradiates to toy car, and make remote controller approach toy car be that beam light source is moved forward towards 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 large in change, identify remote control and be intended to advance forward, so the output of control circuit drives toy car to advance forward by the executing agency of advancing.And become large rate of change according to light-sensitive element input voltage signal, can obtain the signal of light beam translational speed, thereby the operating power of controlling motor is controlled the speed that toy car advances, when becoming, beam intensity becomes greatly faster, pace is faster, otherwise slower, realize the control with analog quantity.3, when operator by remote control light beam irradiates to toy car, and make remote controller be that beam light source is moved backward along 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, 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 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 retreats of toy car, when beam intensity diminishes sooner, astern speed is faster, otherwise slower.4, as operator not by remote control light beam irradiates to toy car, at this moment light-sensitive element does not receive light beam, the voltage less (be less than and set threshold values) of IO1, 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 if close afterwards light beam, toy car still keeps original forward travel state, until light beam is again irradiated to toy car and keeps motionless, just makes toy car stop.The action that some toy car does not retreat, only advances or stops, and the action retreating can only be implemented as dead ship condition.
The present invention is in order to narrate the convenience of operation principle, by independently separately narration of the embodiment of Fig. 4.In actual 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 realizes for identifying the remote control that toy car moves forward and backward, and G4 and G5 are for identifying the remote control that realizes left and right turn.Even also can utilize a wherein light-sensitive element of G4 and G5 next compatible as G1, because both recognition technologies are different, in identification and control, can accomplish to carry out work according to different recognition technologies.
Remote controller also can include modulation circuit, makes the remote control light beam band of its transmitting be useful on jamproof modulation intelligence.Carry out modulated beam of light such as adopting oscillating circuit to produce high frequency waves, or adopt coding circuit generation coded message to carry out modulated beam of light.Correspondingly on toy car with the demodulator circuit that modulation intelligence is carried out to demodulation.This belongs to the conventional means of remote control.But remote control light beam of the present invention not carries remote information with the object of modulation intelligence, but: 1, better improve anti-interference, avoid the interference of ambient light; 2, different remote control light beams can not be 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 (on market, just have 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.On toy car, adopt corresponding light-sensitive element and optical filter to carry out cooperating.This technology can be used for different toy cars to carry out remote control, has and is with two functions; Also be used in same toy car, for the remote control of different directions, such as adopting red beam, forward-reverse direction carrys out remote control, and left and right turn adopts green beam to carry out 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.
