■ j DEVICE FOR DETECTING A REMOTE CONTROLLER DRIVING TOYS

The invention relates to a device for identifying a radio-controlled vehicle toy, we they nnyeqeben in the preamble of claim 1 in more detail is.

Radio-controlled vehicle toys have recently been used to an increasing extent. The remote control systems were improved more and more, so that for the relevant functions, especially steering and for the speed forwards and backwards, steering processes similar to the model can be reproduced. Both the steering and the speed can be proportionally regulated in many cases.

The operating process in such vehicle toys, however, is exhausted in driving in an open area or while driving on a previously marked course. There are no further possibilities so far, so that such vehicle toys can become boring.

There is a major disadvantage of radio-controlled vehicle toys compared to vehicle toys from car racing tracks in that an automatic detection of the same has not been possible until now.

On the other hand, with car racing tracks there are many ways to increase the incentive to play. This includes lap counters on a mechanical basis, lap counter on a decorative tromechanical or electronic basis, in the driving

For example, there is a counter in patent application 2833159 has been proposed for car racing tracks by which a variety of driving results are recorded can. This is the number of laps that the participating vehicles have completed. The number of laps can be specified so that the device switches off the entire system after the number of laps has been reached. A cell separation can be carried out, whereby after The time the system is switched off has elapsed. It can always be determined which of the vehicles involved placed first or second. The application is not only for two, but also for three or four vehicles possible. It is also possible to record the smallest lap time, so that in each case it can be determined which vehicle has set a lap record. It is also possible to adjust the speed and read the maximum speed of the various vehicles.

In the patent application 29 39703 a device is proposed in which certain driving conditions are prescribed will. These are, for example, speed limits or overtaking bans. The device monitors compliance with driving regulations, in the event of a violation via a registration device Penalty points are recorded.

For radio-controlled vehicle toys that can drive freely independently of a special, prefabricated racetrack can, e.g. also on squares and paths, there are no such devices for automatic detection. Included ° it would be desirable even with a freely laid out

To be able to drive a course with radio-controlled vehicle toys in races or skill competitions, especially since in the case of train-independent vehicle toys, the game comes very close to reality, so the game is worth it is increased accordingly.

The object of the invention is accordingly to provide a device for identifying a radio-controlled toy vehicle and / or to indicate driving conditions that can be carried out easily and effortlessly on different surfaces such as carpeting, paving or grass can be used is.

This task is part of the preamble of the Father's claim 1 specified device solved, according to the invention according to the characterizing part of claim specified manner.

The stimulus to play with radio-controlled vehicle toys is increased, because in addition to the possibility of one track-independent journey also the play possibilities known at car racing tracks with all possibilities of the Detection are given. In addition, according to the invention equipped radio-controlled vehicle toys not only moving freely, but also on predetermined ones Railways are used.

Further, advantageous refinements of the invention emerge from the subclaims. 30th

The recognition of the vehicle toys and their operating conditions allows in particular an expansion of the previously possible repertoire of rules of the game, which follows

In a special embodiment, an identification strip is used which consists of an insulating carrier material, for example plastic film, with metal foil on both sides of this carrier material at certain points. on is metallized. Segments can be provided on the outside that are connected to a current lead that is led to the outside inside a Faraday cage. The current leads can already ^{be seen in the Faraday 1} cage or outside of the same. In this case, registration is only possible when driving over a specific vehicle.

A major advantage of an identification strip that is built on a flexible material, e.g. a thin film is, is that its shape can be adapted to the terrain, so it can, for example, without difficulty be placed on wavy ground or in hollows. This is especially true of. Meaning if after the special terrain formations have to be driven through according to the respective rules of the game.

The power lines of the individual segments or specific segment groups can, however, also be evaluated separately will. This enables the following rules to be observed automatically:

For example, the middle area of the recognition stripe becomes defined as the bottleneck to be passed. When crossing this area, the corresponding Current leads not connected to a registration device for penalty points. The vehicle receives however, penalty points if it drives on the identification strip at a greater distance from the defined bottleneck. The number of penalty points can be increased as the distance from the bottleneck increases.

It is also possible to define the rules of the game in reverse. A central area of the detection strip becomes for example, as with a target set as the center. There is a maximum number of credit points. The number of good points is correspondingly for the areas following outwards from this central area scaled down.

The production of the mandatory identification strip is very easy and economically possible. The carrier film used, the one on both sides accordingly is coated with metal foil, is placed on top of each other by two folds so that an inside roughness. as a Faraday cage, while above the to the driving part is equipped with segments. The power connection of the segments with the power lines in the The interior of the Faraday's cage can be inserted by eyelets or by a soldered connection or otherwise

The present detection is preferably used to determine that a vehicle has been driven over and that "Recognize" the vehicle. In this way it is possible to control a lap counter. Also a counting device according to patent application 2833159 can be used, so that in the present case all with this device at car racing tracks available options -also with radio remote-controlled Vehicles are available.

In the context of another recognition it is also possible to recognize the vehicle itself and at the same time the Determine the speed at which the vehicle drives over the detection strip. This is given by the provision of at least two points on the vehicle,

which act on the identification strip. Through the measurement

By measuring the time that elapses between the two pulses, the speed can be determined at the same time.

The speed of the vehicle can also be determined thereby be arranged by a generator on the drive axle or on the gearbox, the one The frequency corresponding to the number of revolutions is generated. This fr'equente signal can from the interrogator and converted into a speed display in the evaluation circuit.

It is also possible to provide three points on the vehicle from which the activity necessary for the detection originates. In the simplest case, this is a triangle. The first point gives the first impulse, while the following two points result in two more impulses. Depending on the distance between the two points and depending on the angle at which the vehicle drives on the identification lane, a certain time pattern is given, which also creates the possibility of determining the angle at which the vehicle drives on the identification strip, to determine. This results in more play options. For example, it can be prescribed -25 that the vehicle is approaching a point behind the detection strip.

If so, if the vehicle fired a shot while crossing the detection strip, it would hit the target. It is possible to evaluate this aspect and distribute Dealer Points when properly solution of the problem _s that are registered for vehicles separated from counters. The game process can then be used as a gangster hunt, a war game or as a maneuver of military vehicles with target shooting.

There is also the option of using the identification strip not just to record that a certain vehicle is driving on it, via one or more additional vehicles Features, such as additional lamps on the vehicle floor, can identify a certain driving condition will. This is an off and on process, for example switching the lights on or off, Switching on a horn at a certain tunnel.

In the case of vehicles with additional functions, for example construction vehicles or military vehicles, additional Operations are controlled, for example setting up the cannon on the right or left side, setting up a trigger on the right or left side etc. It is always adhering to a certain Driving regulation, for example with or without lights, can be monitored and the driver a good point or a Penalty point will be given for fulfilling or not fulfilling the present condition.

The electrical connection from the contact segments 31 located on the top to the power supply lines is made by inserting 73 rivets 422_ or some other conductive connection.

The rivet can also be designed so that it is electrically conductive at the top and bottom, however not on the side flank. For example, a sleeve made of * cannot be used over an eyelet made of metal conductive material. Then the metal coating is in the area of the contact segment 31 with the Loop-shaped enclosure 491, which is connected to a power supply 46, connected without an electrical conductive connection with the metal coating on the side according to Figure 1 is established. The loop-shaped Recess 47 u-412 can thus be omitted.

in order to recognize that a vehicle has driven over the contact strip, either from the vehicle _:. information can be transmitted to the contact surface 31, or the vehicle closes two adjacent contacts by means of a correspondingly wide grinder 21

In the case shown in Fig. 5, the contact segments are 31 connected to voltage divider resistors 34. Are parallel to the voltage divider resistors 34 e.g. differential amplifiers 39, which then deliver an output pulse when through the wiper 21 of the Vehicle two adjacent contact segments 31 are short-circuited together. To short circuit two To ensure adjacent contact surfaces by the wiper 21, the contact segments 31 are diamond-shaped formed (see. Fig. 5).

Another possibility for identifying a toy vehicle is that the oscillator frequency of the remote control of the toy in question is given to a contact brush or the like and is transmitted to this when a contact surface 31 is passed over. A signal then occurs between the contact surface 31 and earth potential or a frame 301 surrounding the contact surface 31, which signal is recorded and further processed in a selective detector 76 (cf. FIG. 6). The oscillator frequency can for example be applied to the contact brush characterized in that intermediate ^OJ see the reception antenna of the toy vehicle and the

The surrounding frame 301 serves at the same time to shield the contact surface 31 from external signals.

. If typical frequency electromagnetic signals are used to detect the vehicle, which signals are generated or (selectively) amplified in the vehicle itself, contact-free detection is also possible. For this purpose, the signal generated in the generator T1 is sent to a coil 73 attached to the vehicle floor (FIG. 7. The interrogation device has an receiver coil 71 which receives the signal when the vehicle is driven over and forwards it to the evaluation circuit. This receiving coil 71 can also be designed as a layered conductor track on a carrier film. The evaluation circuit is constructed in accordance with the circuit already described for FIG.

Conversely, it is also possible to operate the coil 71 located in the roadway as an induction coil and with it to apply a transmission signal. In the vehicle there is a resonance circuit on the floor with a typical vehicle resonance frequency built-in, i.e. the oscillator in Fig. 7 is replaced by a reactance 77 and the oscillator is connected to the coil 71 (Fig. 8). 10

Different frequencies are generated in the generators 721-725 and, for example, via Resistors are jointly supplied to the induction loop 71. When driving over the induction loop 71 sucks the resonance circuit 76 from the energy with the same frequency from the induction loop. On the induction loop 71 a multi-channel detector device 76 is connected at the same time. This consists of selective Amplifiers with subsequent rectification and a downstream AC voltage amplifier.

In the embodiments in which by means of one or multiple contact brushes, or contact wiper signals transfer to a contact strip or transfer contacts

Immediately in front of the actual scanning point, a sheet metal strip 17 is mounted, which ensures that the magnet 28 pulls the double contact down in good time so that contact is ensured at the scanning point. ^:

in the following an arrangement will now be described at which the vehicle is recognized by a sliding contact with a vehicle-specific diameter or a number of two or more contact points of the vehicle with typical vehicle spacing on an arrangement of contact segments a corresponding typical vehicle - number of such contact segments bridged.

In all of the following examples, four vehicles to be distinguished were assumed ^{for reasons of JU clarity.} However, the solutions are designed in such a way that significantly more vehicles can be distinguished by the recognition.

In the solution in Fig. 11, the finish line consists of

-24-INSPECTED

two parallel rows of contacts 32, 33. The left row of contacts 32 is connected to a pole of a constant voltage source 36 via resistors 34, which all have the same value. The right contact row 33 is divided into individual groups. The individual contacts 3.12 of these groups are electrically short-circuited to one another and are fed to individual peak voltage voltmeters 37. The resistors 35 are the measuring resistors.

Contact disks .21 with different diameters, än ^ ^Vw ', are placed on the underside of the various vehicles (Fig. 1.2) ϊ If contact disks are used, it is advantageous to use contact brushes as lane contacts in the lane. Individual contacts can also be used instead of contact disks 211, 212, which are conductively connected to one another (FIG. 13).

The diameters of the contact washers are always chosen so that, for example, the following bridges take place, when a vehicle drives over the contact point.

This means that, depending on the type of vehicle, a different number of contacts 311 in the left row 32 are connected to contacts 312 in the right row 33. A current with a vehicle-typical size thus flows to the respective contact group of the right-hand row 33, and a vehicle-typical voltage (peak voltage) drops across the measuring resistor 35.

This results in corresponding (peak) voltages

where η is the number of bridges.

A very typical peak voltage value is thus obtained at the measuring resistor 35 for each vehicle.

The peak voltmeter 37 has at its output an evaluation circuit 5, so that a certain measured peak voltage generates an output pulse on the Output lines A, B, C or D.

Since two or more vehicles can pass the finish line at the same time, the right-hand lane contacts become 312 divided into groups. This avoids that

In other words, the other way around: If a certain voltage value is set at the resistor, the evaluation circuit can 5 immediately determine after the peak voltmeter 37 how many and which vehicles are at the same time have crossed the finish line and pass this information on to the output lines ABCD.

In the solution in Fig. 15, the same roadway contacts 31 as in Fig. 14 are used. Also lie here the. individual lane contacts on voltage divider resistors 34. The voltage U- must be so large that £ the voltage drop across the resistor is at least 1 V. About 0.7 V drops across diode 38. Through this

Line (1) of the pulse diagram in Fig. 19 shows the timing of the bridging. I.e., initially if only 1 contact is touched, then 2 contacts, 3, 2, 1, and after driving over O. The output A of the decoding circuit goes from L to H when 2 or 3 contacts are bridged (line 2). This L-H jump caused no reaction in the A-NOR gate, since input I is already high. Only the H-L jump sets it Input I briefly on L (line 3). Since input II is at the same time on L (line 4), there is at the output of the Α-gate a positive pulse (line 5).

Example 2 ; Vehicle B crosses the contact line

Initially, the contact disc only bridges two or three contacts when it is retracted (line 6). This is done in the decoding circuit 51 recognized as vehicle A (line 7). The output of the decoder circuit 51 goes from L to H. This L-H jump causes no reaction in A-NOR gate 53, since input I is already at H lies. If four lane contacts are now bridged by the contact disk, the decoding circuit delivers Η signal to the B line. Since the B line is also connected to input II of the A-NOR gate 53, there is now a Η signal at input II (line 9). By bridging the contact disc of four contacts the decoding circuit 51 recognizes that no more contact is made with A-vehicle. The Α signal goes from H to L and thus also the input I of the A-NOR gate 53 (line 8). The H-L transition can be the output of the Do not set gatters to H because input II

• y yes is on H- during this time.

There is an H pulse at the output of the B-NOR gate 53 (Line 13), because the input II on L (line 12) and the input I by the H-L jump on the B line if Vehicle B only bridges 3 contacts - is briefly set to L (line 11).

When driving out, the decoding circuit would still recognize A once, although vehicle B is moving out.

Here, the time delay circuit 52 in Fig. Ensures that within a certain period of time on Two A-signals in quick succession cannot be passed on at the output.

This additional circuit complexity is in the case of a non-disk-shaped contact arrangement, that is to say in the case of contact pairs not necessary according to Fig. 13 .. With this solution, however, the vehicle must not cross the finish line at an angle travel. Otherwise a wrong contact distance would be recognized, or the contact is temporally like this offset that no more bridging takes place.

To ensure that the vehicles cross the finish line vertically, the following steps can be used Entrance funnel can be used.

If you don't just want to recognize the vehicle, you also want to determine the speed at which it is traveling over the When you cross the finish line, there are solutions like the following example.

On the underside of the vehicles, as shown in FIG. 20, there are three contacts arranged in a triangle

Another way to identify a vehicle toy consists in attaching one or more light sources to the underside of the vehicle, whose light when Driving over the interrogation device acts on reflex light barriers 6 with sensors 61 arranged there and signals triggers.

Alternatively, reflectors can be attached to the vehicle instead of light sources, the light, which emanating from the interrogator, reflect and direct to sensors 61 in the interrogator.

As with the sliding contacts already described above, die_Dimensionierung the reflectors or the mutual spacing of the reflectors or light sources as a characteristic can be selected with which the vehicle toys are distinguished from one another.

In FIG. 22, a vehicle underside is shown schematically, to which a reflector is attached. the typical vehicle size is the length 1 of the reflector

strip.

In the interrogation device there is a in a direction perpendicular to the direction of travel of the vehicle c series of photosensitive elements, e.g. phototransitors, as well as one (or more) light sources arranged parallel to the row of these photo elements, whose light emerges upwards. If the interrogator is driven over, depending on the size of the Reflek-IQ tors of the vehicle a different number of photo elements due to the reflected from the reflector Light is exposed and a corresponding signal is generated in the evaluation circuit.

■ y / j FIG. 23 shows a further possibility for vehicle identification with optical means. According to the upper part of this figure is on the underside of the vehicle in certain A light source is attached at a distance from the center line of the vehicle. The interrogator has a Row of optical sensors 61 on. The vehicle is forced onto a roadway by means of an entry funnel 9, which runs perpendicular to this row of sensors and through its center.

The light source acts when the row of sensors is passed 65, e.g. a light-emitting diode, according to its distance from the vehicle center line to the corresponding Sensor 61, making the vehicle identifiable will.

It should be emphasized that with this arrangement too several light sources can be attached to the underside of the vehicle, as shown in dashed lines in FIG. 23 is indicated. The number and position of the switched on light sources correspond to a certain code, with which makes it possible to identify significantly more vehicles

tify than the number of individual light sources 65 or sensors 61 is.

In the lower part of FIG. 23 a corresponding arrangement is shown in which each sensor 61 has a light source 62 is arranged adjacent to the interrogation device. The vehicle has an or on its underside - when using a code system - also has several reflectors. When they are run over, they turn into light Light sources, above which a reflector 63 of the vehicle is located, in the assigned sensor 61 mirrored (Fig. 24). Instead of individual light sources 62, a continuous, e.g., thread-shaped light source can also be used be arranged parallel to the sensors 61.

As can also be seen in FIG. 23, several such interrogation devices equipped with photosensors be arranged next to each other so that several toys can pass the finish line at the same time.

The light sources in the vehicle or in the interrogation device can be incandescent lamps or light-emitting diodes that be operated in the visible light range or in the infrared range, with DC or AC voltage.

Fig. 25 shows an embodiment for this type of detection in which phototransxtors are used as light sensors and light-emitting diodes with light of changing amplitude are used as light sources. The intensity of the diode light is modulated _{with the frequency f ö.}

the saturation arrives, but a very high external resistance for the alternating light of the diodes 62, since the LC circuit 612 is then on resonance. When driving over the corresponding phototransistor 65, the AC voltage at the collector is amplified in amplifier 613 and rectified.

With the possibility of modulating the intensity of the vehicle's light sources, there is another one Possibility to identify the vehicle or, for example, to display a certain operating status.

For this purpose, depending on the vehicle or its operating state, the light source is equipped with one or more Modulated frequencies. The modulated light is then the information carrier recorded by the light sensors and is decrypted in a decoding or evaluation circuit.

In addition to the embodiments of FIGS. 23-25, FIG. 26 shows the possibility of simultaneously with the Identification of the vehicle also its speed at the moment of crossing the finish line to be able to determine. In the exemplary embodiment, entry funnels 9 were used again. However, that is not necessary if there are two rows of reflex light barriers 6 or photo receivers across the entire width of the lane 61 are distributed.

Another way to identify a toy vehicle and determine its speed Figures 26, 27. On the underside of the vehicles there are either two light sources, e.g. incandescent lamps or LEDs 65, 66 or - analogous to Fig. 25, two reflectors in a very specific type of vehicle

As Fig. 26 shows, with the aid of entry funnels 9, in turn, several such arrangements IQ may be present next to one another in order to be driven over at the same time Allow multiple vehicles to cross the finish line.

When run over by the vehicle from-I ^ Outgoing light in the sensors 610, 612 each generates a signal. If the intensity of the light is not even, but rather modulated, a frequent signal is obtained, as shown in FIG. 28. For the Explanation of how the evaluation takes place is now the distance between the light sources of the vehicle with b and the The distance between the sensors 610, 612 is denoted by a.

At point P of the evaluation circuit results in Crossing the finish line, the following diagram: t is the time in which the first light source 65 from sensor 610 to sensor 612, with ~ ["die Time by which the light source 66 passes over the sensor 610 or 612 later than the light source 65.

Fig. 28 shows a block diagram for the evaluation. From the photo receiver 610 with the downstream amplifier 614, the flip-flop is set by the negative edge of the W pulse. It is reset by the pulse W, which occurs when the infrared diode of the vehicle closes the second at a distance a Photo receiver 612 happened. (See timing diagram Fig. 28).

In the pulse input pauses the counter is always reset (R input).

The finish line here consists of such a film 80, which becomes the active one Area divided into individual segments 81.

AC voltage amplifiers are attached to the individual solar segments 81 83 connected. The advantage of the division into individual segments 81 is that when driving over the scanning point the segment 81 is covered by the vehicle, so that the ambient light is hardly any more can generate a voltage in the solar segment 81. A voltage generated by constant light is also short-circuited by the choke 84. Through this Method is a much better benefit-disturbance ratio to reach. The decoder 51 takes over the frequency evaluation.

c is by the Re The reflector 64 is always reflected in such a way that it hits an IR photo receiver 61 attached to the side.

In addition, the parabolic reflector 64 is dimensioned so that • IQ that the distance from the exit point of the IR light over the reflector 64 to the IR receiver 61 always constant is. As a result, the light energy arriving at the receiving location is always the same, i.e. regardless of whether it is on which part of the roadway the vehicle is located, ic This advantage enables compensating circuits in the evaluation circuit connected downstream of the IR photo receiver save on.

So far it has essentially been shown how the detection and differentiation of the vehicles and possibly also their speed takes place.

In addition, it is also desirable to recognize other driving conditions of the vehicle during game operation to be able to evaluate automatically.

This can be done in the case of the embodiments already described, in which a signal is generated in the vehicle toy and is transmitted to the interrogator, in principle borrowed by a corresponding modulation of this Signal, i.e. this signal contains further information about the relevant driving status transmitted to the query facility.

The swivel mechanism is actuated via the linkage 15. This is connected to the rowing machine 14 on the other hand.
