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...

Abstract

The invention relates to a device (1) for preventing and detecting the falling of an object or of a person on a line (2) of a railway station having a platform (3). The device (1) includes at least one detection device (7) having at least one emitter (8) of a beam (10) and a sensor (9) able to detect this beam (10), and a detection calculator (13) for processing the signals obtained from the sensors (9) and able to communicate safely with at least one signaling system (16a, 16b, 16c) of the station, barriers (4) able to be arranged on the platform (3) to prevent falls, the barriers (4) delimiting between them door opening areas (5), a detection device (7) being arranged in each of them to detect a fall on the line (2).

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...
