Description
Technical Field
The utility model relates to a subway shield door safety anomaly detection technical field especially relates to a subway shield door abnormal events monitoring alarm system based on visual detection.
Background
Subway, as the most important vehicle in city, huge passenger flow also brings the many problems how to control safe riding, and in order to guarantee safety, the main measure of protecting in the subway industry abroad and China for preventing passengers from falling into the rail is to install a shield door between the platform and the rail. With the rapid development of subway laying, the shielding door is used more and more, but because a certain gap exists between the shielding door and a train, the shielding door is in control association with the start and stop of the train, and in addition, due to the reasons that the shielding door per se has faults and the like, the shielding door also brings about other safety accidents, such as: the shielding door is not closed, the train is started or stopped immediately, the shielding door clamps people, and people are secondarily damaged in a gap between the train and the shielding door; these accidents lead to equipment failure and are highly life-threatening.
At present, most of shield doors are also provided with a detection system, such as a PSD anti-pinch system, a position sensitive sensor is arranged above or on the side of a train door and used for detecting whether articles exist in a certain distance in front of the train door, linking the opening of the train door or sending out audible and visual alarm; an infrared detection grating or an ultrasonic detection system is arranged on a platform or a shield door, and whether an object exists in a gap between a vehicle door and the shield door or not is detected by utilizing the infrared correlation receiving and ultrasonic distance measuring principle;
in practical application, however, the above method has certain defects and shortcomings, so that faults still occur occasionally; the position sensitive sensor has low detection precision, and information is reported by mistake, so that unnecessary mistaken parking is caused; the infrared light curtain device often leads to laser correlation cheap because of the resonance or the ground vibration that the train sent when the tunnel is moving, produces the wrong report or lacks the warning, and debugging maintenance is wasted time and energy, can only go on during subway outage, can't exert its effect during the trouble. The ultrasonic ranging sensor is easy to report errors, and the main reason is that the working principle of the ultrasonic ranging sensor is sound wave emission and has the fan-shaped emission characteristic of sound waves, so when the barriers at the passing part of the sound waves are more, the reflected sound waves are more, the interference in the subway environment is more, and the distance is easy to measure by mistake.
SUMMERY OF THE UTILITY MODEL
In view of the above prior art's shortcoming, the utility model aims to provide a subway shield door abnormal event monitoring alarm system based on visual detection for solve the shield door and press from both sides people or press from both sides thing and people's card by the problem of secondary damage in the space between train and shield door.
In order to realize above-mentioned purpose and other relevant purposes, the utility model provides a subway shield door abnormal events monitoring alarm system based on visual detection, include: at least one of the event cameras is selected,
