<p>PROBLEM TO BE SOLVED: To provide a radio communication device and the like that are able to identify a communication object among a plurality of radio communication devices.SOLUTION: A first distance acquisition unit 311 of a radio communication device acquires a first distance between two management devices and a radio communication device from reception radio wave strength. A second distance acquisition unit 312 acquires a second distance between each management device and the radio communication device from the reception radio wave strength. A sensor position acquisition unit 313 acquires a third distance between each management device and sensor terminals from each management device, and determines the position of each sensor terminal on the basis of a preset channel of each sensor terminal. A photographing position determination unit 314 determines the position of the radio communication device on the basis of the preset position of each management device, the first distance, the positions of the sensor terminals, and the second distance between the sensor terminals and the radio communication device. A communication object identifying unit 315 identifies a sensor terminal in a direction detected by a direction detection unit 360 from the position of the radio communication device as a communication object of the radio communication device.</p> |
