RADIO COMMUNICATION DEVICE, RADIO COMMUNICATION METHOD AND RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a radio communication device that is easy to maintain.SOLUTION: A radio communication device 10 provided for P-P communications is disposed opposite to a master device or a slave device. A radio transmission and reception unit 120 includes a directional antenna. A memory unit 110 stores reference image data 111 and captured image data 112 that are imaged by an imaging unit 150. The imaging unit 150 has an optical axis directed in the same direction as the radio wave direction of the directional antenna, to capture an image related to a perspective to another opposite radio communication device. An imaging processing unit 160 compares the reference image data 111 with the captured image data 112. From the result of the comparison, a control unit 100 detects and notifies that an obstacle is moving in the radio wave direction.
