<p>PROBLEM TO BE SOLVED: To easily detect a passenger who is close to a train in excess or who is caught in a door, by executing the pattern recognition on the basis of the reflected beam optical pattern information, and detecting the passengers or an obstacle at the start of a car of a train. SOLUTION: A reflected beam optical detecting means 22 detects the reflected light 22a of a beam light 20a applied onto a door surface or the like, and generates the reflected beam optical pattern information 22b which is a cut surface pattern. A TV camera 23 picks up the images or a door of a train, and a side wall part of a door opening, from an upper part of a platform, to generate the image information 22c as the reflected beam optical pattern information 22b. A safety monitoring control means 30 executes the pattern recognition on the basis of the reflected beam optical pattern information, detects a passenger who is close to a car in excess, or an obstacle such as a matter which interferes the car, at the start of the train, and outputs the warning information 30a when the dangerous condition is found, to give the warning.</p> |
