  The wireless reader device 200 can basically perform a function of reading information of the wireless tag 300 by communicating with the wireless tag 300 located in the vicinity. For example, the wireless reader device 200 may be provided in the form of an NFC card reader, an RFID reader, a WIFI tag reader, or a mobile terminal or a smartphone with a near field communication function.

  Then, the wireless reader device 200 can send out a wireless signal for reading tag information. The radio signal can be a radio signal transmitted in the form of an electromagnetic field. In general, the wireless tag 300 demodulates a radio wave signal transmitted in the form of an electromagnetic field, and sends product data and sensor information stored therein to a reader device according to the demodulated signal.

  2, a toy 100 according to an embodiment of the present invention includes a controller 110, a wireless signal receiving coil 120, a power drive circuit 130, and one or more light emitting devices 140A, 140B,.

  First, the radio signal receiving coil 120 receives a radio signal sent from the radio reader device 200, generates an induced electromotive force, and transmits the induced electromotive force to the power drive circuit 130.

  The wireless signal receiving coil 120 may include at least one coil for primarily receiving a wireless signal. The wireless signal receiving coil 120 may have a form of an oscillating means for generating electric power necessary for the operation of the wireless tag 300 for receiving a general wireless signal. In addition, since the radio signal receiving coil 120 generates only the induced electromotive force from the radio signal, the radio signal receiving coil 120 does not include a modulation means and a demodulation means, and can implement its function with a minimum.

  In particular, the radio signal receiving coil 120 can generate an induced electromotive force in accordance with a magnetic field change generated from radio waves of a radio signal sent by the radio reader device 200. For this, the radio signal receiving coil 120 includes a metal layer on which an antenna having a specific pattern is formed for receiving radio signals and generating an induced electromotive force, or a back surface of the toy 100 in a printed metal form. Can be included. The user can cause the wireless signal receiving coil 120 to generate an induced electromotive force by touching the back surface of the toy 100 in the direction of the wireless reader device 200.

  Further, the radio signal receiving coil 120 can provide a part of the generated induced electromotive force to the control unit 110 to provide an operation power source for the control unit 110. The control unit 110 can receive a part of the induced electromotive force and control the overall operation of the toy 100, and controls the power drive circuit 130 to perform power application control to the light emitting elements 140A, 140B,. can do.

  The radio signal receiving coil 120 transmits all or part of the induced electromotive force generated to the power drive circuit 130, and the driving power source is supplied by the light emitting elements 140A, 140B,. To be applied.

  Here, the power drive circuit 130 may apply power to the one or more light emitting elements 140A, 140B,... According to a control signal received by the controller 110.

Emit light at a predetermined intensity and hue or blink. Can do.

  On the other hand, the control unit 110 controls the power drive circuit 130 so that the induced electromotive force generated by the radio signal received by the radio signal receiving coil 120 is applied to the power sources of the one or more light emitting elements 140A, 140B,. .

  For this, the controller 110 may include a distance sensing unit 111, a lighting adjustment unit 113, a brightness adjustment unit 115, and a hue adjustment unit 117.

  First, the distance sensing unit 111 measures the distance from the wireless reader device by the induced electromotive force.

  The wireless signal transmitted by the wireless reader device 200 can form an electromagnetic field in the periphery, and the strength of the magnetic field can be increased by reducing the distance between the wireless reader device 200 and the toy 100. As a result, the magnitude of the induced electromotive force generated primarily by the radio signal receiving coil 120 can also be increased.

  Therefore, the distance sensing unit 111 can sense the distance from the wireless reader device 200 based on the magnitude of the induced electromotive force generated primarily by the wireless signal receiving coil 120.

  In the above-described embodiment of the present invention, the distance sensing unit 111 is described as being separately provided in the control unit 110, but the present invention does not limit the implementation method of the distance sensing unit 111. The distance sensing unit 111 may be included as a part of the control unit 110 circuit function, or may be implemented as a simple comparison circuit or included as part of the power drive circuit 130 function. The distance sensing unit 111 converts information about the sensed distance into a digital value and outputs it, or outputs a comparison result with a predetermined distance critical value, or the magnitude value of the induced electromotive force itself as distance information. It can also be output by sensing with.

  In addition, the brightness adjusting unit 115 can vary the power level of the driving power source applied to the one or more light emitting elements according to the sensed distance.

  The brightness adjustment unit 115 varies the intensity of the driving power applied to the one or more light emitting elements 140A, 140B,... According to the sensed distance, thereby adjusting the brightness of each light emitting element 140A, 140B,. Can be adjusted.

  For example, the brightness adjustment unit 115 is changed to the second stage when the sensed distance is equal to or greater than a predetermined critical value and the driving power supply is maintained at the first stage and approaches the critical value or less. As described above, a control signal for varying the power level of the drive power supply can be output to the power drive circuit 130.

  Under the control of the brightness adjusting unit 115, the power drive circuit 130 provides a driving power source with the light emitting elements 140A, 140B,..., And the current for changing only the brightness while maintaining other values. Size control can be performed.

  Meanwhile, the hue adjusting unit 117 may generate a hue control signal for controlling the hue of the one or more light emitting devices according to the sensed distance.

  The hue adjusting unit 117 adjusts the hue of each of the light emitting elements 140A, 140B,... By changing the digital signal of the driving power applied to the one or more light emitting elements 140A, 140B,. Can do.

  For example, the one or more light emitting devices 140A, 140B,... May include a plurality of LED light sources including at least one of RED, GREEN, and BLUE. Accordingly, the hue adjusting unit 117 controls the digital value corresponding to the power signal output applied to each light emitting element 140A, 140B,... To emit at least one of the RED, GREEN, and BLUE light sources. can do. As a result, the hue of the light emitting elements 140A, 140B,... Exposed to the outside can be changed to a preset color.

  For example, when the sensed distance is equal to or greater than a predetermined critical value, the hue adjustment unit 117 is close to a critical value or less while maintaining the digital signal corresponding to the driving power source with the digital signal corresponding to the first hue. In such a case, the digital signal corresponding to the second hue can be controlled to be changed.

  Further, the hue adjusting unit 117 can output a control signal for changing the pulse signal of the driving power source to the power drive circuit 130.

  The power drive circuit 130 provides driving power by the light emitting elements 140A, 140B,... By the control of the hue adjusting unit 117, and the pulse or duty for changing only the hue while maintaining other values. Ratio control can be performed.

Meanwhile, the lighting controller 113 may generate a lighting control signal for controlling a lighting pattern of the one or more light emitting elements according to the sensed distance.
For this purpose, the lighting control unit 113 varies the pulse signal or duty ratio of the driving power applied to one or more of the light emitting elements 140A, 140B,... According to the sensed distance, thereby changing the light emitting elements 140A, 140B,. The lighting pattern can be adjusted.

  For example, when the sensing distance is equal to or greater than a predetermined critical value, the lighting adjustment unit 113 can control the driving power source so that the first light emitting element is lit, and when the distance is equal to or greater than the second critical value. The first light emitting device and the second light emitting device can be lit together.

  In addition, the lighting adjustment unit 113 can also randomly change the frequency of the pulse signal of the driving power source according to a sensed distance according to a predetermined pattern (lighting cycle pattern). For example, it is possible to change the frequency and pulse width, or to have a plurality of lighting cycle patterns depending on the distance in advance, and to output a control signal corresponding thereto to the power drive circuit 130.

  Such control of the control unit 110 makes it possible to provide different brightness, hue, or lighting pattern changes depending on the distance between the toy 100 and the wireless reader device 200, and the user can enjoy new fun. In addition, the curiosity of the operation between the toy 100 and the wireless reader device 200 can be induced to provide a learning effect by understanding the principle.

  3 and 4 are drawings for illustrating an operation example between a toy and a wireless reader device according to an embodiment of the present invention.

  3 and 4, the toy 100 may include a robot-shaped or doll-shaped housing, and the first light emitting element 140A may be disposed so as to be exposed on the front surface of the toy 100 housing.

Although not shown in detail, the radio signal receiving coil 120 is disposed on the back surface of the toy 100 housing, so that the radio signal from the radio reader device 200 can be received more easily.

  The wireless reader device 200 may include various reader devices including a short-range communication module.

  For example, the wireless reader device 200 may be a card reader for reading card information from a wireless tag card located in the vicinity. Thereby, the wireless reader device can send a magnetic field signal for card reading to the periphery.

  The wireless reader device 200 may be a mobile terminal including a short-range wireless communication module. Generally, in the case of a mobile terminal, the short-range wireless communication module can be selectively turned on and off, and in the case of the mobile terminal in this embodiment, it is assumed that the short-range wireless communication module is on, that is, is accompanied. In addition, the toy 100 according to the embodiment of the present invention becomes operable.

  First, as shown in FIG. 3 (A), the induced electromotive force output from the wireless signal receiving coil 120 is a predetermined critical value when the distance between the toy 100 and the wireless reader device 200 is more than a certain distance. May be: Accordingly, the first light emitting element 140A can be maintained in a state where it does not emit light, or its brightness can be maintained in a state where it is in the first stage.

  Then, as shown in FIG. 3B, when the user moves the toy 100 and the distance from the wireless reader device 200 becomes a certain distance or less, the guidance output from the wireless signal receiving coil 120 The electromotive force can be increased above a predetermined critical value. Accordingly, the first light emitting device 140A may be changed in a state of emitting light, or may be changed in a state where the brightness is a second step higher than the first step.

  4 shows an embodiment in which the lighting control of the light emitting elements 140A, 140B,... Is individually performed according to the distance from the wireless reader device 200.

For example, the first light emitting element 140 </ b> A may be disposed on the chest part of the toy 100 and the second light emitting element 140 </ b> B may be disposed on the eye part of the toy 100. The light emitting elements 140A and 140B may have different lighting distance critical values from the wireless reader device 200 to be turned on.

  In the case of the toy 100 shown in FIG. 4A, the brightness of each light emitting element 140A, 140B is maintained at a certain value or less.

  Then, as shown in FIG. 4B, when the user moves the toy 100 and the distance from the wireless reader device 200 becomes shorter than the first distance, the wireless signal receiving coil 120 outputs the signal. The induced electromotive force can be increased to a predetermined first critical value or more. Accordingly, the first light emitting element 140A can be changed in a state of emitting light. However, the second light emitting element 140B may not emit light because the toy 200 is in a state that is more than the second distance.

  Thereafter, as shown in FIG. 4C, when the user moves the toy 100 and the distance from the wireless reader device 200 becomes shorter than the second distance, the signal is output from the wireless signal receiving coil 120. The induced electromotive force can be increased to a predetermined second critical value or more.
