Embodiment Construction
[0033] refer to figure 1 and 2 , a metro station with a platform 3 The prevention and detection device 1 for objects or persons falling on a railway 2 comprises physical barriers 4 arranged on certain areas of the platform 3, between which an area called a door opening area 5 is defined . The door opening area is arranged to coincide with the door P of the railway vehicle V parked at the station. The barrier 4 is fastened firmly to the platform, as close as possible to the edge 6 of the platform 3 . They include, where necessary, a lateral retour preventing anything from entering the space comprised between the edge 6 of the platform 3 and the barrier 4 . The barrier 4 is for example a viewing window or a glass door, held in a rigid fixed frame on the platform, a low wall or any other fixed structure on the platform 3, and is high enough to prevent people from falling onto the railway 2 from the platform.
[0034] Thus, the barriers 4 are not movable relative to the statio...

#CMT# # / CMT# The device (1) has a platform (3) provided with a detection unit (7) that comprises a ray transmitter. A sensor detects rays (10). A detection controller treats signals from the sensor, and safely communicates with an indication system of a railway station. Barriers (4) e.g. glazed doors, are arranged on the platform for preventing fall of an object / person. The barriers delimit the detection unit between opening zones of a door (5), where the detection unit is placed in one of the barriers to detect the fall of the object / person on the platform. #CMT# : # / CMT# An independent claim is also included for a method for preventing and detecting fall of an object / person on a track of a railway station. #CMT#USE : # / CMT# Device for preventing and detecting fall of an object / person on a track of a railway station. #CMT#ADVANTAGE : # / CMT# The device is simple by utilizing less number of parts, and the parts of the device are not mobile, so that the maintenance of the device is simple and inexpensive, thus preventing fall of parts on the platform in the opening zones of the door. The device is effective even when the vehicle enters in the railway station. The barriers are maintained in a fixed rigid framework compared to the platform to prevent falling of person from the platform on the track. The barriers are not mobile compared to the platform to allow an emergency evacuation. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a schematic top view of a device for preventing and detecting fall of an object / person on a track of a railway station when a railway vehicle is in at an entry of the railway station. 1 : Fall preventing and detecting device 3 : Platform 4 : Barriers 5 : Door 7 : Detection unit 10 : Rays.
Description
technical field [0001] The invention relates to a device for preventing and detecting the falling of objects in a monitoring area, especially on a traffic railway, and a method for detecting the falling of an object on a railway. Background technique [0002] In order to detect falling objects on the railway, for example in a subway station, it is known to use a video camera arranged above the railway. However this solution is not entirely satisfactory as it requires extensive and costly installation and maintenance operations and does not work correctly if the camera view is obstructed. [0003] Another known solution is to arrange several photodiodes along the transit track, for example one diode every 25 cm. These diodes emit light beams and we can detect their interruption. This solution requires a large number of diodes and detectors, which also means extensive and expensive installation and maintenance operations. [0004] Another known solution to stop objects or p...
