GROUND DEVICE AND CLOSING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a ground device capable of avoiding erroneous communication by an over-reach incoming call, and a closing device using the ground device.SOLUTION: A ground device 1 is installed at every station and wirelessly transmits an entrance signal s1 to enter a ground radio network constructed at each station by adding a station number specific to an installation station. The ground device 1 forms a closing device in combination with an on-vehicle device 2. That is, the ground device 1 forming the closing device according to the present invention wirelessly transmits the entrance signal s1 to the on-vehicle device 2. The on-vehicle device 2 has station number information on each station and enters a ground radio network at a target station when a station number added to the received entrance signal s1 accords with station number information of the target station.
