Description

Technical Field

[0001] The utility model relates to the technical field of high-speed railway platform sliding doors, and in particular to a novel flat-opening platform sliding door. Background Art

[0002] High-speed rail platform doors are used to separate the train running area from the platform waiting area, preventing passengers from falling into the train running track while waiting, and protecting passengers' personal safety. In addition, platform safety doors can also display lead information, reduce the wind pressure and noise on passengers when the train passes, and create a safe and comfortable waiting environment for passengers. For urban rails such as subways and light rails, the model of each train is the same, so the position of the doors of each car is the same, so that the sliding doors in the platform doors correspond one-to-one with the doors of the train. However, there are many types of high-speed trains and intercity trains in my country. Different models lead to different lengths of vehicles, which affects the position of the doors. The sliding doors in traditional platform doors cannot correspond one-to-one with the doors of the vehicles.

[0003] In addition, in order to ensure the safety of the 1.2m running area between the platform door and the train, it is necessary to check before departure whether there are people or objects that may affect the safety of the train. The current detection methods are as follows:

[0004] Infrared light curtain method: The device of infrared light curtain method consists of infrared transmitter, infrared receiver and host. This technology consists of infrared transmitter emitting characteristic light to the corresponding infrared receiver, and the receiver detecting the characteristic light emitted by the transmitter, and judging obstacles on the straight light path according to the signal characteristics detected by the receiver. Since the signal emitted by the transmitter is infrared light, the light spot gradually increases with the increase of detection distance, so it is not suitable for long-distance detection. In actual use, due to the diffuse reflection of platform doors and car doors, when there are obstacles in reality, the transmitted signal is easy to bypass the obstacles and cause false detection.

[0005] Laser detection method: The laser detection method uses a receiver to detect the characteristic light emitted by the transmitter, and determines whether there is an obstacle on the straight light path based on the signal characteristics detected by the receiver. This method also has the problem of easy false detection; for curved platforms, the false alarm rate increases accordingly as the number of devices increases. The equipment is installed between the train and the platform door, which exceeds the equipment limit of the platform, posing a major safety hazard to driving safety, and the vibration generated by the train may cause the laser to deviate from the corresponding receiver.

[0006] Laser beam method: The laser beam method consists of a laser transmitter, a laser receiver and a host. This technology uses a laser transmitter to emit invisible light to the corresponding laser receiver, and the receiver detects the invisible light emitted by the transmitter. Obstacles on the straight light path are determined based on the signal characteristics detected by the receiver. Due to the perimeter limitations of the intercity platform door installation position, laser beams cannot cover all gaps and are prone to missed reports. Utility Model Content
