Example

[0055] First embodiment

[0056] figure 1 It is a schematic diagram showing the structure of the elevator safety device according to the first embodiment of the present invention.

[0057] Such as figure 1 As shown, the center-divided elevator door adopting the safety device of this embodiment has an elevator door 1, a threshold that guides the lower part of the elevator door 1, and a door sill that is installed at the upper part of the elevator door 1. The elevator door pulley 3 and the elevator door guide rail 4 for the elevator door pulley 3 to travel. In addition, it also has an elevator door control device 5 and an elevator control device 6. The elevator door control device 5 is used to control the motor that opens and closes the elevator door 1 and performs sensor signals of various safety devices related to the opening and closing of the elevator door. For detection and the like, the elevator control device 6 controls the operation of the elevator car based on the state of ...

Abstract

The invention provides a safety device of an elevator, capable of detecting a rope-shaped foreign matter and a belt-shaped foreign matter with little diameter and reducing the repair and maintenance operation intensity and making the passenger quickly clear the foreign matter without effecting the appearance shape and when detecting the foreign matter. The safety device. The safety device of the elevator comprises lighting devices (8) arranged between an elevator door (1) at the elevator car side and its door sill (2) and between an elevator door (1) at the hall side and its door sill and capable of linearly lighting on the whole front-surface width of the elevator access door, a camera (10) arranged on the upper part of the elevator access door and an image processing unit (11) for processing the image obtained by the camera, in the safety device, the lighting device lights and the camera obtains the image on the door sill surface and the front end surface of the elevator door and the image processing unit extracts the area lighted by the lighting device and the presence of the foreign matter is detected based on whether the lighted area is separated or not.

Description

Technical field [0001] The present invention relates to an elevator safety device and an elevator safety control method that can avoid danger at an elevator entrance provided with elevator doors, and in particular to an elevator that can avoid accidents in which rope-like foreign objects such as pet traction ropes are caught by elevator doors. Safety device and elevator safety control method. Background technique [0002] In order to prevent passengers getting on and off the elevator or their hand luggage from being caught by the elevator door when the elevator door is closed, a detection rod called elevator door safety shoe is installed at the end of the elevator door. When passengers come into contact with the front surface of the elevator door and press the elevator door safety shoe toward the opening direction of the elevator door, the elevator door stops closing and opens again, thereby preventing accidents such as passengers being trapped by the elevator door. [0003] Howev...
