RADIO COMMUNICATION EQUIPMENT FOR ELEVATOR

摘要

PROBLEM TO BE SOLVED: To provide radio communication equipment capable of ensuring stable transmission quality by enlarging a radio communication distance in the elevating route of an elevator. SOLUTION: The radio communication equipment is provided with an antenna mounted in an elevating route and an antenna mounted on a lift cage; two antenna cables whose transmission loss characteristics are different corresponding to the respective antennas; and a means for adjusting a radio transmission power when transmitting and radio receiving sensitivity when receiving, by an antenna cable switching device and communication controller, such as an elevator operation controller and a lift cage controller for conrolling the switching of the switching device at each time when transmitting and receiving.
