<p>PROBLEM TO BE SOLVED: To provide a radio image monitor system that applies image monitor and monitor control of installation in a tunnel or at a remote place by means of radio relay. SOLUTION: This system has a controller 6 that controls the facilities, including a camera 5 photographing a monitored image and a sensor 7 or the like and is provided with a transmission terminal 1 that sends image monitor data, a relay terminal 2-N that relays radio signal, and a central monitor 4 that conducts monitor control through the transmission reception by the transmission terminal 1 and the relay terminal 2-N via a communication interface 3. Thus, monitor data and monitor image data of the installation in a tunnel or at a remote place are sent to the central monitor 4 by a radio wave without the need for wiring, the central monitor 4 monitors and the image of the installation and the central monitor 4 sends a radio wave control signal to control the facilities in a tunnel or at a remote place.</p> |
