Description

Technical Field

[0001] The utility model relates to the technical field of safety anti-pinch equipment, in particular to an intelligent safety anti-pinch equipment for platform shielding doors of subway stations. Background Art

[0002] The subway screen door is a high-tech product that integrates the disciplines of architecture, machinery, materials, electronics and information, and is used in subway platforms. The screen door separates the platform from the train running area, and is automatically opened by the control system. The subway screen door is a high-tech product that integrates the disciplines of architecture, machinery, materials, electronics and information, and is used in subway platforms. The screen door separates the platform from the train running area, and is automatically opened by the control system. The subway screen door is divided into closed, open and half-height types, among which the open and half-height types are usually called "safety doors" and only play a role in safety and beauty. The closed type is usually called "screen door" by people, and it is also the most commonly used one.

[0003] In the prior art, there is no anti-pinch structure for subway platform screen doors.
