  A helicopter-shaped aircraft 3 will be described. The flying body 3 includes a body 10 formed from a lightweight material such as polystyrene foam or plastic, and the body 10 includes a main body portion and a tail portion. A rotatable upper rotor 13 and a lower rotor 14 are mounted above the main body of the machine body 10. The upper rotor 13 and the lower rotor 14 rotate in different directions on the same rotor shaft, and the reaction torque is offset by the reverse rotation of the rotors 13 and 14, so that the aircraft in flight 10 can be prevented from rotating counterclockwise to the right or left, and the flying vehicle 3 in flight can turn left and right. A stabilizer 17 that rotates in conjunction with the upper rotor 13 and keeps the posture of the machine body 10 stable is mounted immediately below the upper rotor 13. Further, a detection device 7 including a light emitting unit 19 and a light receiving unit 20 for detecting an obstacle such as a ceiling existing above the body 10 is disposed above the tail part of the body 10. The size of the aircraft 3 is such that the aircraft 10 has a total length of about 180 mm to 210 mm, a width of about 35 mm to 55 mm, a height of about 40 mm to 65 mm, a rotor diameter of about 165 mm to 210 mm, and a total weight of about 20 g to 70 g. This is a small flying object 3 that can be played indoors.

  The upper rotor 13 is pivotally attached to the rotor shaft and is pivotally attached to the tilting shaft in a state in which the upper rotor 13 can tilt with respect to the rotor shaft. Therefore, the upper rotor 13 can rotate on the rotor shaft and can tilt with respect to the rotor shaft. The upper rotor 13 and the lower rotor 14 have wings formed in opposite directions. When the rotational speed of the upper rotor 13 is higher than the rotational speed of the lower rotor 14, the flying object 3 turns to the left and the lower rotor 13 When the rotational speed of the rotor 14 is faster than the rotational speed of the upper rotor 13, the flying object 3 is configured to turn rightward.

In this process (step S210), when the control mode switching lever 58 is switched to the voice control mode or is in the voice control mode in advance, the control unit 100 determines whether voice input is possible. Executability determination processing (step S213) is executed, and a voice input waiting state is entered. Next, the control unit 100 executes a voice input presence / absence determination process (step S215) to determine whether or not there is a voice input. If there is a voice input, the voice identification determination process (step S215) identifies voice instructions by the voice identification unit 107. Step S217) is executed. In the voice input presence / absence determination process (step S215), if the voice input has not been performed for a predetermined time or more, the voice control mode is terminated.

  In the voice identification determination process (step S217), when the voice can be identified, the control unit 100 causes the signal generation means 109 to generate an operation signal corresponding to the voice, and waits for a predetermined time (about 200 mSec (milliseconds)) ( After step S219), an operation signal transmission process (step S221) for transmitting the generated operation signal to the flying object 3 is executed. Then, the control unit 100 waits for a predetermined time after the operation signal transmission process (step S221), and executes the voice input availability determination process (step S213) again. Further, in the voice identification determination process (step S217), if the voice cannot be identified, the voice input availability determination process (step S213) is executed again.

  Next, control on the aircraft 3 side in the voice control mode will be described. FIG. 6 is a time chart at the time of the voice control mode in the flying object 3. In this figure, a waveform diagram of electric power supplied to the motors 31 and 32 of the flying object 3 is also described. When the flying object 3 receives a signal corresponding to the first instruction, which is a voice instruction “start engine”, the flying object side control circuit supplies power to each motor 31, 32 up to 10% by about 1% / 100 mSec. And then maintain 10% power supply. At this time, the flying object 3 does not fly and only the rotors 13 and 14 are rotated. This “%” indicates the ON state pulse width, that is, the DUTY ratio for each cycle of, for example, 2 mSec of the electric power supplied to the motors 31 and 32. The maximum output state in which power is always supplied is obtained, and in the case of 10%, a state in which power having a pulse width of 1/10 period is supplied is shown.

  When a signal corresponding to the second instruction, which is a voice instruction “higher”, is received after the first instruction, the aircraft control circuit supplies power to each motor 31 and 32 up to 70% by about 3% / 100 mSec. And after maintaining the state of 70% for about 1800 mSec, the control is executed to reduce the 5% power and maintain the power of 65%. At this time, the flying object 3 floats in the air with 70% electric power, and then slowly rises due to inertia. Also, if the second instruction is received when the power supply value is 50% or more, such as after the second instruction is given, the flying vehicle side control circuit sets the current power supply value without increasing the power to 70%. Control to increase by 5% is executed. That is, the flying object control circuit executes control to increase the power supply value by 5% when the second instruction is continuously issued at a predetermined time interval. Furthermore, if the second instruction is received after the fourth instruction or when the power supply value becomes 50% or less due to power reduction or the like, the aircraft-side control circuit powers up to 70% by about 5% / 100 mSec. , And after maintaining the state of 70% for about 1000 mSec, the control for maintaining the power supply of 65% is executed.

  When a signal corresponding to the third instruction, which is a voice instruction “HOLD”, is received after the second instruction, the aircraft-side control circuit maintains a state where the power is reduced by 5% for about 400 mSec, and then the power is reduced. After maintaining the state increased by 5% for about 1.7 Sec, the power is decreased again by 5%. At this time, the flying object 3 maintains substantially the same altitude. In addition, when the third instruction is received after the fourth instruction, which is the voice instruction “lower”, the flying vehicle side control circuit maintains the state where the power is increased by 5% for about 400 mSec, and further increases the power by 5%. Then, after maintaining this state for about 800 mSec, control is executed to maintain the state lowered by 5% for about 50 mSec and further reduce the power by 5%. At this time, the vehicle 3 slows down by slightly increasing the power by 5% twice and increases slightly, and then maintains the altitude by decreasing the power thereafter. Further, if the second instruction is the second instruction after the second time, and the second instruction is immediately before, the aircraft-side control circuit maintains the state where the power is reduced by 5% for about 1600 mSec, and then the state where the power is increased. After maintaining about 600 mSec, the control of lowering the power by 5% is executed again. As described above, in the third instruction, by slightly raising and lowering the electric power slightly, lift is applied to the flying object 3 in time series and the altitude is maintained. The third instruction is not limited to the above-described control, and by raising and lowering the power supplied to the motors 31 and 32, an appropriate ascending force is applied to the flying object 3 to keep the altitude substantially constant. Control may be performed.

  When a signal corresponding to the fourth instruction, which is a voice instruction “lower”, is received, the aircraft-side control circuit reduces the power supply to the motors 31 and 32 by 5%, and then receives the fourth instruction signal. Each time the control is performed, control is performed to decrease the power by 5%. When a signal corresponding to the fifth instruction, which is a voice instruction “stop”, is received, the aircraft-side control circuit executes control to completely stop the power supply to the motors 31 and 32, and the aircraft 3 Each of the rotors 13 and 14 is completely stopped from rotating.

  When the auxiliary operation switch 59 is operated in the voice control mode, the flying vehicle side control circuit increases the power supply to the motors 31 and 32 by 5% and the auxiliary operation switch 59 is continuously pressed a plurality of times. Increases the power supply to the motors 31 and 32 by 5%. In this process, when an instruction is given by voice in the voice control mode, the time required from the start to the end of the utterance by the user and the identification process for the input voice are made until one instruction is given and the next instruction becomes possible. There is a time lag of about 1 Sec, and during this time it is impossible to give instructions to the aircraft 3 by voice, so it is not possible to cope with cases where it is necessary to quickly increase the number of revolutions of the motors 31 and 32. This is to make it possible to cope with such a situation by operating the operation switch 59. In the voice control mode, when the turning operation lever 53 and the trim adjustment dial 54 are operated, the manual operation is given priority, and turning and trim adjustment are possible.

  Furthermore, in the voice control mode, when the altitude control lever 52 is operated, if the expected value of the power value due to the position of the altitude control lever 52 is smaller than the power value due to the voice control, the voice control is given priority, and the expected value Is higher than the power value by voice control, priority is given to the control by the altitude control lever 52.

  Next, a method of playing the helicopter toy 1 having such a configuration will be described. First, the operator switches on the aircraft-side power switch 21 shown in FIG. 2 and the transmitter-side power switch 55 shown in FIG. 3, and presses the standby button 63 after the power lamp is lit. Next, as an initial setting of the helicopter toy 1, the operator tilts the altitude control lever 52 of the transmitter 5 slightly upward to rotate the rotors 13 and 14, and in this state, the fuselage 10 rotates left and right. The rotation of the rotors 13 and 14 is adjusted with the trim adjustment dial 54 so as not to occur.

  When playing in the voice control mode, the operator tilts the control mode switching lever 58 toward the voice control mode with the altitude control lever 52 of the transmitter 5 positioned at the lowest end, A voice instruction “start engine” is issued toward the voice intake port 57, and the rotors 13 and 14 of the flying object 3 are started.

  Then, when the operator gives a voice instruction “higher”, the flying object 3 floats in the air and enters a flying state. Thereafter, the operator can fly the flying object 3 by operating the turning operation lever 53 while adjusting the altitude of the flying object 3 by voice instructions such as “higher”, “hold”, and “lower”. it can. Further, when the operator gives a voice instruction “stop”, the rotors 13 and 14 are completely stopped, and the flying object 3 descends and landes.

  Further, when playing in the manual control mode, as with the conventional helicopter toy 1, the game can be played by adjusting the altitude with the altitude operation lever 52 and turning left and right with the turning operation lever 53. If the altitude control lever 52 is tilted upward vigorously during play in this manual control mode, the aircraft 10 will rise at a stretch, but since the flying vehicle 3 is equipped with the detection device 7, The possibility of the aircraft 10 colliding with an obstacle can be reduced.

  Further, when charging the rechargeable battery 37 of the flying object 3, the operator takes out the charging code 61 from the charging code storage part 60 of the transmitter 5, connects the charging terminal at the tip to the charging terminal of the flying object 3, Set the transmitter-side power switch 55 of the transmitter 5 to the charging mode. When the transmitter-side power switch 55 is put into the charging mode, the charging lamp is turned on when the rechargeable battery 37 is being charged, and the charging lamp is turned off when the rechargeable battery 37 is fully charged.

  According to the helicopter toy 1 of the present invention as described above, the transmitter 5 is provided with voice identifying means that is means for identifying voice instructions and signal generation means that is means for generating control signals corresponding to the voice instructions. In addition, by preparing in advance a control signal corresponding to the power capacity supplied from the battery or its change, it is possible to control by voice, easy to control, and different from the case of manual control. A helicopter toy that can provide taste can be provided. Therefore, even a beginner or a person with a handicapped hand can enjoy playing, and a helicopter toy that everyone can enjoy can be provided.

  In addition, since the electric power is intermittently supplied to each motor 31, 32 in response to the second instruction by voice, the altitude of the air vehicle 3 is adjusted. It is possible to prevent the altitude from changing greatly.

  Further, when an auxiliary operation switch 59 is provided and 5% level of electric power is added for each operation of the auxiliary operation switch 59, it is necessary to raise the altitude quickly. It is possible to respond quickly to situations where voice maneuvers are not in time.

  In addition, when a signal corresponding to the third instruction is received, if the immediately preceding instruction is the second instruction, the power supplied to the motor is sequentially reduced, increased, and lowered, and the immediately preceding instruction is executed. Is the fourth instruction, it is possible to maintain the altitude of the flying object 3 by performing the control of increasing, increasing, decreasing, and decreasing the power supplied to the motor in order. Ring can be easily realized.

  Then, in the voice control mode, it is necessary to raise the flying object 3 according to the second instruction continuously made within a predetermined time interval and / or according to the operation on the auxiliary operation switch 59. Since the power supply to each of the motors 31 and 32 is executed in an enhanced manner, the expected value of the power supply corresponding to the second instruction due to the power reduction of the rechargeable battery 37 or the like is set for each motor. When the power is not supplied to 31, 32, the power supply value for each of the motors 31, 32 can be increased by a predetermined value, and thus the expected value of power supply can be obtained.

  In the above-described embodiment, the helicopter-shaped flying body 3 includes the upper rotor 13 and the lower rotor 14, but may include a main rotor and a tail rotor that prevents the main rotor from rotating the aircraft. It is also possible to adopt a configuration in which two motors are arranged at the front and rear, and the design can be changed freely. The present invention is not limited to the contents described in the present embodiment, and can be freely changed without departing from the gist of the invention.
