Abstract

(57) [Summary] [PROBLEMS] To detect the position of a model aircraft or the like that has been lost in the field of radio control. A combination of a device mounted on a model aircraft or the like and periodically transmitting a signal radio wave and a device for receiving a signal radio wave from the device and detecting a position of the model aircraft or the like is used. You can find missing model aircraft. In addition, it is possible to find a missing model aircraft or the like by using a device that detects a position where the model aircraft or the like exists by using a device that receives a weak radio wave radiated from a control receiving device such as a model aircraft. . In addition, a combination of a device that is mounted on a model aircraft or the like and emits a signal radio wave in response to an external command radio wave and a device that receives the signal radio wave from this device and detects the position of the model aircraft or the like is used. By doing so, a missing model aircraft or the like can be found.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is a device that can be used for detecting the position of a model aircraft or the like in the field of radio control.

[0002]

[Prior art]

 In a conventional position checking device for a model aircraft or the like, a sound is emitted using an electronic buzzer or the like, and a person hears the transmitted sound to use for searching for a model aircraft or the like.

[0003]

[Problems to be solved by the invention]

 In the conventional method, for example, when searching for a model aircraft that has crashed, if the crash point is far away or in the grass, the sound from the position confirmation device may be attenuated and inaudible. There is a problem that the method is useless.

[0004]

[Means for Solving the Problems]

 In the present invention, a method of detecting the position of a model aircraft or the like from the radio wave using the radio wave instead of the conventional sound.

In the present invention, radio waves from a device mounted on a model aircraft or the like and periodically transmitting signal radio waves are used.

In the present invention, a weak radio wave radiated from a radio receiver of a control device mounted on a model aircraft or the like is used.

[0007] In the present invention, the use of radio waves instead of the dial tone reduces the attenuation as compared with the case where the dial tone is used, and is effective for searching for a model aircraft or the like.

[0008]

[Means for Solving the Invention] In the present invention, a signal receiver transmitted from a model aircraft or the like is received by a dedicated receiver.

In the present invention, a weak radio wave radiated from a control receiving device such as a model aircraft is received by a dedicated receiver.

[0010]

[Embodiment of the invention]

 FIG. 1 shows an apparatus configuration of the present invention according to claim 1. The model aircraft 1 and the like 1 are equipped with a device 2 for periodically transmitting signal radio waves, and the dedicated receiver 3 is equipped with a directional receiving antenna. When the camera is pointed at, detection with maximum sensitivity is possible.

The direction in which the model aircraft or the like exists can be detected by confirming the maximum reception sensitivity while rotating the antenna of the dedicated receiver 3. Also, the dedicated receiver 3 calculates and displays the distance to the model aircraft 1 or the like from the receiving sensitivity at that time.

FIG. 2 shows an apparatus configuration of the present invention according to claim 2. The dedicated receiver 6 is provided with a directional receiving antenna. When the antenna is pointed in the direction in which the model aircraft 4 exists, the model receiver 5 is mounted on the model aircraft 4. It can detect radiated weak radio waves with maximum sensitivity.

The direction in which the model aircraft 4 or the like 4 exists can be detected by checking the maximum receiving sensitivity while rotating the antenna of the dedicated receiver 6. Also, the dedicated receiver 6 calculates and displays the distance to the model aircraft 4 from the receiving sensitivity at that time.

FIG. 3 shows a configuration of the present invention according to claim 3. The model aircraft 7 is equipped with a device 8 for transmitting a signal wave in response to an external command wave. The detector 9 transmits a signal radio wave to the device 8. The device 8 returns the signal radio wave immediately after receiving the signal radio wave. The detector 9 receives a radio wave from the device 8.

The detector 9 is provided with a directional receiving antenna, and can detect radio waves from the device 8 with maximum sensitivity when the antenna is pointed in the direction in which the model aircraft 7 exists. . By checking the maximum receiving sensitivity while rotating the antenna of the detector 9, the direction in which the model aircraft or the like exists can be detected.

The detector 9 measures a time interval from the time when the signal radio wave is transmitted to the device 8 to the time when the signal radio wave is received from the device 8. From this time interval, the distance to the model aircraft 7 is detected and displayed.

Although the present invention has been described in detail based on the embodiments of the present invention with specific examples, the present invention is not limited to the above contents and does not depart from the scope of the present invention. All modifications and changes are possible as long as it is possible.

[Effect of the invention]

 In the conventional method, for example, when searching for a crashed model aircraft, etc., if the crash point is far away or in the grass, the sound from the position confirmation device may be attenuated and may not be heard. Although it did not help, the present invention makes it possible to search for model aircraft, etc., even under adverse conditions as described above.
