  The LED illumination system and the illumination system form a direct current power source, connect a plurality of light emitting diodes (LEDs) in series or in parallel, and perform light emission control by applying a constant voltage or flowing a constant current thereto. This type of illumination system is used for electrical decorations such as Christmas trees, and beautifully enlivens the atmosphere as a wire illumination system with a plurality of LEDs.

  By the way, blinking that repeats turning on and off of the wire illumination system includes a pattern in which all the LEDs are turned on all at once, a pattern that turns off all at once, a half that is turned on, and a half that is turned off. . In both lighting patterns, it is important that a plurality of LEDs are turned on / off / flashed in order with synchronization. The former can be realized only by turning the power on and off. In the latter case, the power is turned on and off alternately by two lines of wiring, or the blinking cycle preset for each LED is used. The thing provided with the control circuit chip which blinks can be considered.

  In this system, dozens or hundreds of LEDs are wired with wires, so it is difficult to decorate, and the layout change is troublesome, and it is easy to change to LEDs with different LED colors or blinking patterns. , Maintenance is not possible.

  As a solution to this problem, it is conceivable to wirelessly feed individual LEDs using electromagnetic induction. However, it is possible to easily turn on and off all LED devices at once, but it is possible to control half of the numbers to be turned on all at once in the same period and half of the numbers to be turned off all at once in the same period. It cannot be done only by turning the power on and off.

  In view of this, a non-contact power feeding system has been proposed in which a plurality of LED devices are made to shine with a lighting pattern command signal wirelessly using electromagnetic induction (for example, Patent Document 1). A combined signal of the power signal and the lighting pattern command signal is used. The lighting pattern command signal is detected from the power received by each LED device. The LED device side has a driver for LED lighting control, and performs lighting control corresponding to a preset lighting pattern command signal.

  That is, a plurality of LED devices receiving the same signal decode the same signal pattern and express the same lighting pattern preset by the LED lighting driver incorporated in the device. Can be a lighting pattern.

However, a plurality of LED devices divided into a plurality of systems cannot be turned on in synchronization with different lighting patterns from a plurality of LED devices of other systems.
In addition, it has been proposed that addresses are assigned to a plurality of LED devices, and address data is sent before a lighting pattern command signal to express only a specific LED device with a specified lighting pattern. As a result, a plurality of LED devices are divided into several groups, which enable lighting control in synchronization with different lighting patterns. In this addressing method, the above-described pattern can be wirelessly repeated in which half is turned on and half is turned off.

Furthermore, the plurality of light emitting devices M5 belonging to the fifth group G5 are arranged in a circle so as to surround the light emitting devices M4 of the fourth group G4 arranged in a circle.

  As shown in FIG. 3 (a), the light emitting devices M1 to M5 of the groups G1 to G5 include a secondary coil L2, a capacitor C, a circuit unit 5 including an IC chip, a load including a semiconductor chip, and light emission as a light emitting element.

(Electrical configuration of the LED lighting device 3)
Next, the electrical configuration of the LED lighting device 1 configured as described above will be described.
(Power supply device)
As shown in FIG. 4, the power feeding device 3 is roughly composed of a primary coil L <b> 1, a control unit 7, a high frequency inverter circuit 8, and a command unit 9.

The high-frequency inverter circuit 8 is an oscillation circuit and applies the generated inverter voltage V1 to the primary coil L1 as alternating power.
The control unit 7 includes a control circuit 7a and a modulation circuit 7b. The modulation circuit 7b drives and controls the high-frequency inverter circuit 8, and generates a modulation signal MS for modulating the inverter voltage V1 generated by the inverter circuit 8. Based on the command signal SS from the command unit 9, the control circuit 7a outputs the modulation signal MS generated by the modulation circuit 7b to the high frequency inverter circuit 8, and modulates the inverter voltage V1 generated based on the modulation signal MS. Let

  In the present embodiment, the modulation circuit 7b is an amplitude modulation circuit, and modulates the inverter voltage V1 of the alternating power applied by the high frequency inverter circuit 8 to the primary coil L1, that is, the amplitude value of the inverter voltage waveform. In the present embodiment, as shown in FIG. 6, when the modulation signal MS is input to the high-frequency inverter circuit 8, the amplitude value of the inverter voltage V <b> 1 decreases and the modulation signal MS is input to the high-frequency inverter circuit 8. When not, the amplitude value of the inverter voltage V1 is increased.

  The command unit 9 is a circuit that controls the timing at which the control unit 7 outputs the modulation signal MS to the high-frequency inverter circuit 8 and the period during which the modulation signal MS is output. And the command part 9 comes to output the command signal SS which controls the control part 7 so that the inverter voltage V1 of the alternating power applied to the primary coil L1 is modulated with the pattern shown in FIG. Yes.

Therefore, the alternating power of the inverter voltage V1 amplitude-modulated in the pattern shown in FIG. 6 is applied to the primary coil L1, and an alternating magnetic flux based on the alternating power subjected to the amplitude modulation is generated.
(Light emitting devices M1 to M5)
As shown in FIG. 4, the light emitting devices M1 to M5 of each group G1 to G5 are configured by a secondary coil L2, a capacitor C, a circuit unit 5, and a light emitting diode (LED) 6.

  The secondary coil L2 is linked with the alternating magnetic flux generated from the primary coil L1 in a state where the light emitting devices M1 to M5 are fitted and fixed in the fitting recess 4a that is recessed on the surface of the base 4. The alternating power applied to the coil L1 is received. The secondary coil L2 connects the capacitor C between both terminals, and outputs received power relative to the alternating power applied to the primary coil L1.

  As shown in FIG. 6, the secondary voltage V2 of the received power has a modulated voltage waveform because the alternating power applied to the primary coil L1 is modulated. When the modulation signal MS is input to the high-frequency inverter circuit 8 (when the amplitude value of the inverter voltage V1 is small), the amplitude value of the secondary voltage V2 of the received power becomes small, and the modulation signal MS is supplied to the high-frequency inverter circuit 8. When not inputted (when the amplitude value of the inverter voltage V1 is large), the amplitude value becomes large.

The secondary coil L2 outputs the received power of the secondary voltage V2 indicating the voltage waveform having the pattern shown in FIG.
As shown in FIG. 5, the circuit unit 5 includes a power receiving circuit 5a, a detection circuit 5b, a command circuit 5c, and a power control circuit 5d.

The power receiving circuit 5a is a circuit that shapes the received power (secondary voltage V2) from the secondary coil L2, and outputs the waveform-shaped secondary voltage to the detection circuit 5b.
The detection circuit 5b performs envelope detection on the waveform-shaped secondary voltage, and outputs a detection signal SG1 including the detected square wave shown in FIG. 6 to the command circuit 5c.

The command circuit 5c receives the detection signal SG1 and generates a lighting control signal SX for driving the LED 6 based on the detection signal SG1.
Here, as described above, the light-emitting devices M1 to M5 of the groups G1 to G5 perform the lighting operation of the group-specific lighting pattern simultaneously for the alternating power for each group. Therefore, in this embodiment, the configuration of the command circuit 5c of the light emitting devices M1 to M5 is different for each group.

  More specifically, first, the command circuit 5c of each light emitting device M1 belonging to the first group G1 outputs the detection signal SG1 composed of a square wave detected by the detection circuit 5b while the H level first signal shown in FIG. 1 lighting control signal S1 is output to the power control circuit 5d of the next stage. The power control circuit 5d is configured to pass a drive current through the LED 6 in response to the H-level first lighting control signal S1.

  Accordingly, each light emitting device M1 belonging to the first group G1 is configured such that the LED 6 continues to be lit while the alternating current magnetic flux is generated from the primary coil L1 regardless of whether or not the power feeding device 3 performs amplitude modulation.

  Next, the command circuit 5c of each light emitting device M2 belonging to the second group G2 performs amplitude modulation when the power feeding device 3 is not amplitude-modulated and based on the detection signal SG1 made of a square wave. When the detection signal SG1 is negative, the H-level second lighting control signal S2 shown in FIG. 6 is output to the next-stage power control circuit 5d. The power control circuit 5d is configured to flow a drive current to the LED 6 in response to the second lighting control signal S2 at the H level.

  Therefore, each light emitting device M2 belonging to the second group G2 is when the power feeding device 3 is not amplitude-modulated and when the power feeding device 3 is amplitude-modulated and the detection signal SG1 at that time is a negative period. The LED 6 is turned on.

  Next, the command circuit 5c of each light emitting device M3 belonging to the third group G3 is based on the detection signal SG1 composed of a square wave when the power feeding device 3 is not amplitude-modulated and when the power feeding device 3 is amplitude-modulated. When the detection signal SG1 is positive, the H-level third lighting control signal S3 shown in FIG. 6 is output to the next-stage power control circuit 5d. Then, the power control circuit 5d allows a drive current to flow through the LED 6 in response to the H-level third lighting control signal S3.

  Accordingly, each light emitting device M3 belonging to the third group G3 has a time when the power feeding device 3 is not amplitude-modulated and a time when the power feeding device 3 is amplitude-modulated and the detection signal SG1 at that time is a positive period. The LED 6 is turned on.

  Next, the command circuit 5c of each light emitting device M4 belonging to the fourth group G4 is when the power feeding device 3 is amplitude-modulated based on the detection signal SG1 made of a square wave, and the detection signal SG1 is negative. During the period, the H-level fourth lighting control signal S4 shown in FIG. 6 is output to the power control circuit 5d in the next stage. The power control circuit 5d is configured to flow a drive current through the LED 6 in response to the H-level fourth lighting control signal S4.

  Accordingly, each light emitting device M4 belonging to the fourth group G4 is configured such that the LED 6 is turned on when the power feeding device 3 is amplitude-modulated and the detection signal SG1 at that time is a negative period.

  Next, the command circuit 5c of each light emitting device M5 belonging to the fifth group G5 is the time when the power feeding device 3 is amplitude-modulated based on the detection signal SG1 made of a square wave, and the detection signal SG1 is positive.

(Specific electric circuit of LED lighting device 1)
Next, an example of a more specific electric circuit of the LED lighting device 1 configured as described above by amplitude modulation will be described with reference to the drawings.

FIG. 7 shows an example of a specific electric circuit of the power feeding device 3. FIG. 8 shows an example of a specific electric circuit of each of the light emitting devices M1 to M5.
In FIG. 7, the high-frequency inverter circuit 8 of the power feeding device 3 has a resonance capacitor Cx, and the resonance capacitor Cx is connected in parallel with the primary coil L1 to form an LC resonance circuit.

  In the LC resonance circuit, a parallel circuit of a diode D1 and a resistor R1, an N-channel MOS transistor Q1 as a switching element, and a voltage dividing circuit including a first resistor Ra and a second resistor Rb are connected in series. The series circuit is connected to the DC power source Es. In addition, a series circuit of a resistor R2 and a capacitor C1 is connected to the DC power source Es. Furthermore, the connection point N1 between the resistor R2 and the capacitor C1 is connected to the gate terminal of the MOS transistor Q1 via a series circuit of a primary coil L1, a feedback coil Lx constituting an oscillation transformer, and a resistor R3.

  The high-frequency inverter circuit 8 has a bias control transistor Q2 made of an NPN transistor, the collector terminal of which is connected to the gate terminal of the MOS transistor Q1, and the emitter terminal of which is connected to the negative terminal (ground) of the DC power supply Es. ing. The base terminal of the bias control transistor Q2 is connected to the source terminal of the MOS transistor Q1, and a capacitor C2 is connected between the base and emitter.

  The high-frequency inverter circuit 8 configured in this way is said to be a one-stone self-excited voltage resonance type inverter circuit, and since this oscillation operation is easily understood from, for example, Japanese Patent No. 3391999, its details are omitted. An alternating magnetic flux having a constant frequency is generated from the primary coil L1.

  By the way, in the high frequency inverter circuit 8, when the resistance value of the voltage dividing circuit composed of the first resistor Ra and the second resistor Rb changes, the amplitude value of the sinusoidal inverter voltage V1 of the primary coil L1 changes. Specifically, when the resistance value of the voltage dividing circuit decreases, the alternating power injected into the primary coil L1 increases and the amplitude of the inverter voltage V1 increases.

  Therefore, a switching first transistor Q3 made of an NPN transistor is connected in parallel to the second resistor Rb of the voltage dividing circuit made up of the first resistor Ra and the second resistor Rb. When the first transistor Q3 is turned on, the second resistor Rb is short-circuited, the resistance value of the voltage dividing circuit becomes the resistance value of the first resistor Ra, and the resistance value of the voltage dividing circuit becomes small.

  Therefore, during normal operation, the first transistor Q3 is turned on to increase the alternating power injected into the primary coil L1 to increase the amplitude of the inverter voltage V1. Conversely, during modulation, the first transistor Q3 is turned off. Thus, the alternating power injected into the primary coil L1 is reduced to reduce the amplitude of the inverter voltage V1, thereby performing amplitude modulation.

The modulation circuit 7b includes an astable multivibrator 11, and a low-frequency square wave output signal E is output from an output terminal P.
The control circuit 7 a has a switching second transistor Q 4 made of an NPN transistor, and a collector terminal is connected to a base terminal of the first transistor Q 3 of the high-frequency inverter circuit 8. The collector terminal is connected to the output terminal P of the modulation circuit 7b via the resistor R4. Further, the emitter terminal is connected to the ground. Furthermore, the base terminal of the second transistor Q4 receives the command signal SS from the command unit 9 via the resistor R5.

  Therefore, when the H-level command signal SS is input from the command unit 9, the second transistor Q4 is turned on and the first transistor Q3 is kept off. On the other hand, when the L level command signal SS is input from the command unit 9, the second transistor Q4 is turned off, and the low frequency square wave output signal from the astable multivibrator 11 to the base terminal of the first transistor Q3. E is applied. As a result, the first transistor Q3 is turned on / off based on the low-frequency square wave output signal E from the astable multivibrator 11.

The command unit 9 includes a microcomputer 12 and outputs a command signal SS to the second transistor Q4 of the control circuit 7a. That is, the command signal SS is a signal that determines this amplitude modulation pattern, that is, a different lighting display pattern for each of the light emitting devices M1 to M5 of the groups G1 to G5. Then, the microcomputer 12 generates a command signal SS for determining different lighting display patterns for the light emitting devices M1 to M5 of the groups G1 to G5.
(Light emitting device M1)
In FIG. 8, the light emitting device M1 of the first group G1 has a secondary coil L2 and a capacitor C connected in parallel with the secondary coil L2. A series circuit in which an LED 6 and a resistor Rz for current control are connected in series is connected between both terminals of the secondary coil L2.

  In this case, the amplitude of the primary coil L1 is modulated, and the received power modulated to the terminal of the secondary coil L2 is applied to the LED 6. At this time, the modulated voltage is applied to the LED 6, but the degree of modulation is such that the brightness of the LED 6 does not feel a change due to the modulation.

Accordingly, each light emitting device M1 belonging to the first group G1 is configured such that the LED 6 continues to be lit while the alternating current magnetic flux is generated from the primary coil L1 regardless of whether or not the power feeding device 3 performs amplitude modulation.
(Light emitting device M5)
The light emitting device M5 of the fifth group G5 has a secondary coil L2 and a capacitor C connected in parallel with the secondary coil L2. A series circuit of the LED 6 and a resistor Rz for current control and a power control circuit 5d constituting the second transistor are connected in series, and the series circuit is connected between both terminals of the secondary coil L2.

  The secondary coil L2 is connected to the detection circuit 5b via a rectifying diode D2 constituting the power reception circuit 5a. The detection circuit 5b includes a capacitor C3 and a resistor R6, performs envelope detection, and outputs a detection signal SG1. The waveform of the detection signal SG1 is a square wave having an L level when the primary side is not modulated and an H level when the primary side is modulated. Then, the detection signal SG1 is output to the high-pass filter circuit 13 constituting the next-stage command circuit 5c.

  In the high-pass filter circuit 13, a series circuit of a resistor R7 and a capacitor C7 and a parallel circuit of a resistor R8 and a capacitor C8 are connected in series, and the series circuit is connected to the detection circuit 5b. The high-pass filter circuit 13 receives the detection signal SG1, and outputs an output signal corresponding to the detection signal SG1 as a lighting control signal SX (fifth lighting control signal S5) from a connection point N2 between the capacitors C7 and C8.

  When the detection signal SG1 changes from L level to HL level (when the primary side changes from non-modulation to modulation), the lighting control signal SX (fifth lighting control signal S5) is changed from L level to H level around the ground. When the detection signal SG1 changes from the H level to the L level (when the primary side changes from modulation to non-modulation), a square-wave signal waveform changes from the H level to the L level around the ground. The lighting control signal SX (fifth lighting control signal S5) is output to the power control circuit 5d at the next stage.

  The power control circuit 5d includes a switching third transistor Q5 made of an NPN transistor and a resistor R9 connected between the base and emitter of the third transistor Q5. The third transistor Q5 has a collector terminal connected to the cathode terminal of the LED 6 and an emitter terminal connected to the other terminal of the secondary coil L2.

  The third transistor Q5 inputs the lighting control signal SX from the high pass filter circuit 13 to the base terminal. The third transistor Q5 is turned on when the lighting control signal SX is at the H level, and is turned off when the lighting control signal SX is at the L level.

That is, when the primary side is modulating, the third transistor Q5 is turned on and the LED 6 is lit. Conversely, when the primary side is not modulated, the third transistor Q5 is turned off, and the LED 6 is turned off. Accordingly, each light emitting device M5 belonging to the fifth group G5 is configured such that the LED 6 is turned on when the power feeding device 3 is amplitude-modulated.
(Light emitting device M2)
The light emitting device M2 of the second group G2 has the same configuration as the light emitting device M5 except for the power control circuit 5d of the light emitting device M5 described above. Therefore, for convenience of explanation, the light emitting device M2 will be described only for the power control circuit 5d.

  The power control circuit 5d of the light emitting device M2 includes an inverting circuit before the third transistor Q5. The inversion circuit includes an inversion transistor Q6 made of an NPN transistor and resistors R10 and R11. The inversion circuit inverts the lighting control signal SX from the high-pass filter circuit 13, and the inverted lighting control signal BSX (second lighting control signal S2) is third. Output to the base terminal of transistor Q5.

  The third transistor Q5 is turned off when the lighting control signal SX is at the H level, and turned on when the lighting control signal SX is at the L level. That is, when the primary side is modulating, the third transistor Q5 is turned off and the LED 6 is turned off. On the contrary, when the primary side is not modulated, the third transistor Q5 is turned on and the LED 6 is lit.

Accordingly, each light emitting device M2 belonging to the second group G2 is configured such that the LED 6 is turned on when the power feeding device 3 is not amplitude-modulated.
(Light emitting device M4)
The light emitting device M4 of the fourth group G4 is different from the power control circuit 5d of the light emitting device M5 described above, and is newly provided with an auxiliary power supply circuit 5e. Therefore, for convenience of explanation, only the power control circuit 5d and the auxiliary power supply circuit 5e will be described for the light emitting device M2.

  The third transistor Q3 of the power control circuit 5d constituting the first transistor circuit is connected in parallel with the series circuit of the resistor Rz and the LED 6. The light emitting device M4 has a new auxiliary secondary coil L3 that links the alternating magnetic flux generated from the primary coil L1, and the received power output from the auxiliary secondary coil L3 is smoothed with the rectifying diode D3. Is supplied to an auxiliary power supply circuit 5e comprising a capacitor C9.

  The auxiliary power supply circuit 5e generates a DC voltage (a voltage slightly larger than 0.7 volts) from the received power output from the auxiliary secondary coil L3, and the DC voltage is supplied via a resistor R12 provided in the power control circuit 5d. A bias voltage is applied to the base terminal of the third transistor Q5.

Therefore, in each light emitting device M4 belonging to the fourth group G4, the LED 6 is turned on when the power feeding device 3 is amplitude-modulated and the detection signal SG1 (lighting control signal SX) at that time is a negative period. It has become.
(Light emitting device M3)
The light emitting device M3 of the third group G3 is the same as the light emitting device M4 except for the power control circuit 5d of the light emitting device M4. Therefore, for convenience of explanation, only the power control circuit 5d of the light emitting device M3 will be described.

  The power control circuit 5d of the light emitting device M3 includes an inverting circuit before the third transistor Q5. The inversion circuit includes an inversion transistor Q7 made of an NPN transistor and resistors R13, R14, and R15. The inversion circuit inverts the lighting control signal SX from the high-pass filter circuit 13, and the inverted lighting control signal BSX (third lighting control signal S3). Is output to the base terminal of the third transistor Q5.

That is, the LED 6 of the light emitting device M3 performs a lighting operation opposite to that of the LED 6 of the light emitting device M4.
By configuring as described above, different lighting display patterns are expressed on the light emitting devices M1 to M5 of the groups G1 to G5 only by applying alternating power that is amplitude-modulated to the primary coil L1 of the power feeding device 3. be able to.
(Second Embodiment)
Next, a second embodiment will be described with reference to FIG.

  In the present embodiment, the first embodiment performs amplitude modulation in the power feeding device 3 to express different lighting display patterns for the light emitting devices M1 to M5 of the groups G1 to G5. Instead, it is characterized in that frequency modulation is performed.

In the present embodiment, as shown in FIG. 4, the modulation circuit 7b of the control unit 7 provided in the power feeding device 3 is a frequency modulation circuit 7e as shown in FIG.
That is, the frequency modulation circuit 7e inputs the command signal SS from the command unit 9 that controls the timing for performing frequency modulation and the period during which the frequency modulation is continued through the control circuit 7a. Then, the frequency modulation circuit 7e frequency modulates the alternating power applied to the primary coil L1 by the high frequency inverter circuit 8 based on the command signal SS.

  The waveform of the received power of the secondary coil L2 changes to a frequency-modulated waveform, but the circuit unit 5 of the light emitting devices M1 to M5 can acquire the detection signal SG1 in the first embodiment.

Therefore, similarly to the first embodiment, by simply applying the frequency-modulated alternating power to the primary coil L1 of the power feeding device 3, different lighting display patterns are respectively provided to the light emitting devices M1 to M5 of the groups G1 to G5. Can be expressed.
(Third embodiment)
Next, a third embodiment will be described with reference to FIGS.

  In the present embodiment, in the frequency modulation of the second embodiment, the circuit composed of the secondary coil L2 and the capacitor C provided in the light emitting devices M1 to M5 is adjusted so as to be tuned for each variable frequency. The values of the secondary coil L2 and the capacitor C are adjusted for each of the light emitting devices M1 to M5.

FIG. 10 is an electric block circuit diagram of the LED lighting device 1 including the light emitting devices M1 and M2 of the first group G1 and the second group G2.
In FIG. 10, the modulation circuit 7b of the control unit 7 provided in the power feeding device 3 is a frequency switching circuit 7f.

  That is, the frequency switching circuit 7f can alternately modulate two types of frequencies of the alternating power applied by the high-frequency inverter circuit 8 to the primary coil L1. Then, the frequency switching circuit 7f receives, via the control circuit 7a, a command signal SS from the command unit 9 that controls the timing for performing the two types of frequency modulation and the period during which the frequency modulation is continued.

In addition, the secondary voltage V2a of the feeding power is set to a large value with respect to the inverter voltage V1 of the alternating power modulated to one frequency.

  The light emitting device M2 of the second group G2 sets the inductance of the secondary coil L2 and the numerical value of the capacitor C (Cb) so as to resonate in parallel with the other of the two types of frequencies, as shown in FIG.

In this embodiment, the capacitor C (Ca, Cb) is connected in parallel to the secondary coil L2. However, the capacitor C (Ca, Cb) is connected in series to the secondary coil L2, and series resonance is performed. You may comprise.

  Further, since the ratio of the magnitudes of the secondary voltages V2a and V2b of the received power can be increased by greatly shifting the two frequencies, the circuit unit 5 of the light emitting devices M1 and M2 is connected to a rectifier circuit or the like as shown in FIG. The lighting of the LED 6 can be clearly controlled only by the power receiving circuit 5a.

When the difference between the two frequencies is small, as shown in FIG. 12, if the frequency detection circuit 5f is provided and the received power is controlled accordingly, the light emitting device M1 of the first group G1 and the second group The G2 light emitting device M2 can be turned on alternately.

(Fifth embodiment)
Next, a fifth embodiment will be described with reference to FIG.

  In the present embodiment, the power feeding apparatus 3 is newly provided with a transmission antenna, and a transmission signal for lighting control is transmitted from the transmission antenna to each group of light emitting devices, and reception is newly provided for each light emitting device. It is characterized in that lighting control is performed simultaneously on the basis of a signal for lighting control received by an antenna and received by each light emitting device by a receiving antenna.

  The power feeding device 3 is provided with a new transmission antenna AT1 and a signal generation circuit 16. The signal generation circuit 16 generates a 3 MHz carrier wave, amplitude-modulates the carrier wave in response to the modulation signal from the modulation circuit 17, and outputs the carrier wave to the transmission antenna AT1. Here, the modulation circuit 17 is a signal that outputs a signal obtained by amplitude-modulating a 3 MHz carrier wave per second from the command unit 9 via the signal control unit 18 to the transmission antenna AT1 based on the command signal SS. The generation circuit 16 is controlled.
