PURPOSE: A system for controlling illegal boarding of subway is provided, which stores the scene of illegal boarding in a CCD camera with a warning when a passenger passes through an automatic gate by jumping or crawling. CONSTITUTION: The control system includes sensors(5,6,8,9), a computer(12), a CCD camera(11) and a warning device(10) and is placed in an inner part of the gate. The system can judge illegal boarding by using the sensors detecting a pass of a passenger and outputting the detected data to the computer, the output data from the sensors, and the gate data if the tripodal gate is rotated or not. In case of legal boarding, the moving picture inputted by the camera is deleted. In case of illegal boarding, the moving picture is kept in the camera and the warning device is operated at a time. |
