Description
Technical Field
The utility model relates to a barrier detects technical field, and more specifically the utility model relates to an intelligence subway platform shield door foreign matter detector based on laser vision is related to that says so.
Background
At present, a screen door is a device which surrounds a railway platform and a train landing space on the platform in a glass curtain wall mode, is usually installed on the side edge of a subway platform close to a rail and isolates a platform area from a rail area. When the train arrives, the electric door on the glass curtain wall is opened for passengers to get on or off the train.
However, there is a gap with a certain width between the train and the screen door, and when the train is running, a safety accident is easily caused in the gap, thereby causing a great economic loss. In order to avoid the occurrence of the accidents, most subways mainly depend on the mode that a driver drives to advance for manual lookout, the luminous lamp strip of the tail of the vehicle is watched through the head of the vehicle, and whether pedestrians are clamped or foreign matters invade in the middle area or not is judged according to the integrity of the lamp strip. However, in a narrow and long area of more than 100 meters, it is difficult to judge by only manual means, firstly, the requirement for the driver's eyesight is high, and secondly, the driver is easily fatigued, so that the driver can make misjudgment due to subjectivity. In fact, some subway platforms adopt a curve platform, so that a driver cannot judge by looking out the tail of the vehicle through a head of the vehicle. In addition, the gap between the shielding door and the vehicle body is reduced by installing the rubber strip and the flexible baffle on the side, close to the track, of the shielding door of part of the subway, and passengers are prevented from sinking into the gap due to unexpected feet. The method can prevent people-trapping accidents to a certain extent, but the method cannot detect small objects which bring potential safety hazards in driving, has no alarm prompting function, can only prevent the shielding door from being closed, and has poor adaptability.
Therefore, how to provide an intelligent subway platform screen door foreign object detector capable of solving the above problems is a problem that needs to be solved urgently by those skilled in the art.
