ホーム監視装置
Document Type and Number:
Japanese Patent JP4726321
Kind Code:
B2
Abstract:
A platform monitoring system includes a camera for capturing a situation on a platform. An image captured by the camera is transmitted from a light emitter on the ground side as an optical signal and also transmitted from a transmission antenna on the ground side as a radio wave signal. These signals are received by an optical receiver and a reception antenna, respectively, mounted in a leading end portion of a vehicle. When the vehicle is positioned in a region around a stopping position, an image carried by the optical signal is selectively displayed on a monitor disposed near an operator's seat in the vehicle. When the vehicle is positioned out of the region around the stopping position, an image carried by the radio wave signal is selectively displayed on the monitor near the operator's seat in the vehicle.
