Abstract

The invention provides a distributed pressure sensing and light curtain sensing integrated sensing elevator car door. The distributed pressure sensing and light curtain sensing integrated sensing elevator car door comprises door bodies, light curtains, distributed pressure sensing devices, sealing layers and mounting devices, wherein the door bodies are movably mounted on a car body, and are connected to a door driving device; the light curtains are mounted on the sides, near landing doors, of the door bodies, and are used for detecting whether objects exist between the door bodies; the distributed pressure sensing devices are mounted on the sides, near the landing doors, of the light curtains; the distributed pressure sensing devices are mounted on the edges, near each other, of the two door bodies, and are used for generating mutual extrusion when the objects exist between the door bodies; the sealing layers are mounted on the side surfaces, near the other door body, of each door body, are used for sealing gaps between the two door bodies, and are made of elastic rubber materials; and the light curtains and the distributed pressure sensing devices are mounted on the door bodies through the mounting devices. The distributed pressure sensing and light curtain sensing integrated sensing elevator car door solves the problem of incapability of realizing transparent object detection in the prior art.

Description

technical field [0001] The invention relates to an elevator, in particular to a distributed pressure induction and light curtain induction integrated induction elevator car door. Background technique [0002] In the prior art, the elevator car includes: a car body, a car door, a door driving device, a light curtain and a control box. The upper door of the car body is opened and closed by the car door, and a light curtain is installed on the car door. Whether there is an object between the car doors, there are many infrared sensors in the light curtain. The infrared sensor is used to detect whether the infrared rays are blocked to detect whether there is an object. The light curtain is connected to the control box, and the control box is connected to the door drive device. The door drive The device is installed on the top of the car body, the door driving device is connected with the car door, and the door driving device is used to drive the opening and closing of the car doo...
