ある。(Means for Solving the Problems) In order to achieve the above object, the present invention provides a wireless transmission system for mobile bodies in which one mobile body specifies all mobile bodies and transmits data. to the body,
a transmission/reception control unit that controls input/output of data to be transmitted/received; a radio device that transmits/receives data under the control of the transmission/reception control unit; and short-range directivity that transmits a trigger signal for receiving data by the other moving body. contactless transmission means or a reception means for receiving all of the trigger signals from the short-range directional non-contact transmission means, and only when all of the trigger signals are received from another moving body, the transmission and reception control unit I The wireless device is configured to receive and capture data.
上記短距離非接触伝送手段としては赤外線リモコン、ま
たはマイクロ波リモコン等が利用される。As the short-distance non-contact transmission means, an infrared remote control, a microwave remote control, or the like is used.
赤外線リモコン、マイクロ波リモコン等は、指向性が強
く、到達距離が短いため、他の移動体がリモコン指示さ
れることはないので、移動体指定には有効である。Infrared remote controllers, microwave remote controllers, and the like have strong directivity and short range, so other moving objects are not instructed by the remote controller, so they are effective for specifying moving objects.
