  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings of examples in which the present invention is applied to a radio control helicopter.

  FIG. 1 is a block diagram illustrating a configuration example of a control system for a radio-controlled model according to the present invention. In FIG. 1, reference numeral 1 is a transmitter, 2 is a receiver, 2A is a receiver (RF amplification, detection, etc.), 2B is a decoder, 3 is a control module, 31 is a central controller, 311 is an integrated controller, 312 Is a safety management unit, 313 is a buzzer control unit, 314 is a determination unit, 32 is a memory, 321 is a set value storage unit, and 322 is a history storage unit. The sensor unit 4 includes a current sensor 41, a voltage sensor 42, a temperature sensor 43, a rotation sensor 44, a rotation angle sensor 45, and an angular velocity sensor 46. In addition, an appropriate sensor such as an acoustic radar or a radio wave radar can be mounted.

  The control module 3 is connected to a power motor 7, servo motors 8, 9, 10 that control the steering unit, and a battery 27. 5 is a start switch, and 6 is a buzzer. The start switch 5 is a main switch for bringing the radio control helicopter into a maneuverable state. When the start switch 5 is pressed, the device is locked in an on state, power is supplied to the mounted device, and each part is checked by the safety management unit 312 and normality / abnormality is determined by the determination unit 314. The buzzer 6 emits the first pattern sound, the second pattern sound, and the third pattern sound based on the determination by the determination unit 314.

  In this embodiment, the current sensor 41, the voltage sensor 42, and the temperature sensor 43 are installed as sensors that detect the current, voltage, and temperature of the battery. The rotation sensor 44 detects the rotation of the output shaft of the power motor. The rotation angle sensor 25 and the angular velocity sensor are sensors that detect the rotation angle of the steering angle operated by the servo motor and the angular velocity of the airframe, but may be calculated from the number of driving pulses and the pulse width of the cybo motor. Servo motors are installed in parts that perform flight control such as collective pitch, ladder, and aileron.

  The control parameter setting values changed and adjusted by the personal computer (PC) 200 before or after the flight of the radio control helicopter 100 are stored in the setting value storage unit 321 of the memory 32 mounted on the radio control helicopter 100. In this operation, a cable is connected to the connector 33 and transferred from the personal computer 200, and driving characteristics of the power motor, collective pitch, ladder, aileron, and other operation characteristics are set in the memory 32 as control parameters.

  The carrier modulated by each control signal that constitutes the operation command signal transmitted from the transmitter 1 during the period from the start of rotation of the power motor 7 of the radio control helicopter 100 to the levitation, flight, and landing is a receiver mounted on the radio control helicopter 100. 2 is received. The received carrier wave is detected in the receiver, decoded by the decoder 3, and reproduced as various operation command signals. The reproduced operation command signal is processed by the integrated control circuit 311 according to the setting value (control parameter: setting characteristic) stored in the setting value storage unit 321 of the memory 32.

  FIG. 2 is a flowchart for explaining control including normal / abnormal determination procedures in the control system shown in FIG. This procedure begins with the installation of the battery. As described above, the start button must be pressed until a determination is made. The time required to determine normality / abnormality is determined by the operating speed / processing speed of the installed sensor and central control unit (CPU: microcomputer). In fact, as will be described later, it is determined that all necessary sensors are normal. Sufficient time to be used. Details of this procedure will be described below.

  First, when the battery is mounted on the radio control helicopter and connected to the electrical system (process 1, hereinafter referred to as P-1), the safety management unit 312 detects this connection and instructs the buzzer control unit 313 to ring. To do. The buzzer 6 sounds with the first pattern sound (P-2). The first pattern ringing sound informs the operator that the battery is connected and the steering system is energized. The ringing sound is preferably a gentle continuous sound. However, depending on the surrounding noise environment, the sound may be a continuous sound having a good hearing sensitivity, for example, about 1 kHz. However, it is not limited to this. The buzzer volume can be made variable. In addition to the buzzer, the amount of information can be increased by using a speaker or using an LED lamp together.

  When the start switch 5 is pressed and ON is locked, the buzzer 6 is switched to the second pattern sound (P-4). When the start switch 5 is turned on, each part is checked based on a detection signal of a required sensor in the sensor part 4 (P-5). The check time depends on the number of sensor items (n), the processing time of the safety management unit 312 and the determination unit 314. While executing the check, the buzzer 6 continues to output the second pattern sound. The second pattern ringing sound is preferably an engine starter simulated sound. That is, it gives a feeling of tension by giving the operator the same feeling as a radio-controlled model powered by an internal combustion engine. Note that this abnormality determination information can be configured by providing the history storage unit 322 in the memory 32 shown in FIG. The second pattern ringing sound is not limited to this, and may be other appropriate ringing sounds.

  If an abnormality (for example, when the voltage of the battery is lower than a predetermined value) is determined during the execution of the check (P-6), the subsequent check is stopped (P-7). At this time, the buzzer 6 rings back to the first pattern ringing sound. The buzzer 6 continues the second pattern ringing sound until it is determined that there is no abnormality. Instead of canceling the above check, after completing all the checks, the sound may be returned to the first pattern sound so as to notify that there is any abnormality.

  The check items are sequentially advanced (+1), and when there is no abnormality in the check of the predetermined number of items (n) and the required check is completed (P-8), the buzzer 6 is switched to the third pattern sound (P-9). It is desirable that the third pattern ringing sound is an idling pseudo sound of a radio-controlled model powered by an internal combustion engine. That is, when a flight start signal is received from the transmitter, it becomes an alarm signal notifying that the power motor is in a state where it can start rotating at any time (standby state).

  In this standby state, the start of flight, that is, the start signal of the power motor is transmitted from the transmitter, so that the flight is started as follows, or the start signal of the power motor is turned off and the flight is stopped, and the start button is restarted. Press to return when the battery is installed. FIG. 3 is a flowchart for explaining an outline of a maneuver procedure including flying and stopping of the radio control helicopter. The transmitter start switch is turned on (P-10). The safety management unit 312 determines that it is in the standby state described in FIG. 2 (P-11). The power motor 7 starts rotating and the buzzer 6 is turned off (P-12). The radio controlled helicopter is lifted by a lift-up command signal from the transmitter (or a signal for increasing the number of revolutions of the power motor 7), and various flights are performed by various control signals from the transmitter (P-13).

  The radio controlled helicopter is landed by the landing command signal from the transmitter, and the power motor 7 is stopped by the rotation stop command of the power motor 7 (P-14). As the power motor 7 stops, the buzzer 6 resumes ringing in the standby state, that is, with the third pattern ringing sound (P-15). If it is decided to fly again while outputting the third pattern sound, the transmitter start switch is turned on (P-10), and the same procedure is followed. On the other hand, if it is determined in (P-15) not to fly again, the start button is turned off. At this time, the buzzer 6 returns to the first pattern ringing. Furthermore, the buzzer 6 stops ringing by removing the battery. When the start button is not turned off at a predetermined time, the power supply is automatically cut off.

  FIG. 4 is an overall view of a radio control helicopter as an example of a radio control model to which the present invention is applied. The radio control helicopter 100 is equipped with a steering mechanism including a power motor 7, a battery 27, servo motors 8, 9, and 10, a receiver 2, a control module 3, a sensor unit 4, and a gyro in the body part.

  A main rotor 13, a landing gear 16, and the like are disposed on the body, and a till rotor 15 is attached by a shaft 14. The steering mechanism and the power motor are activated by the start button 5 and fly by controlling the steering mechanism with the steering command received by the antenna 17. As described above, the buzzer 6 rings with the first, second, and third pattern ringing sounds. Reference numeral 12 denotes a light emitting diode (pilot lamp), which lights up when the power is turned on to the mounted device.

  In this way, safe handling of the operator and the radio-controlled model can be realized. It goes without saying that the present invention is not limited to a radio control helicopter, but can be similarly applied to a fixed wing radio control aircraft, a radio control automobile, a radio control ship, and other various radio control models.
