Abstract

The invention provides a safety elevator, which can effectively detect motion of passengers and rope-shaped foreign material on the entrance and exit port of the elevator, enhance safety, reduce accidents adjacent to the elevator door, eliminate factors affecting the running efficiency of the elevator and meanwhile make maintenance and examination easier. The safety elevator in the invention is provided with a camera device (5) on the entrance and exit port of the elevator for monitoring the switch of the elevator door. The safety elevator comprises an elevator door control device (3) for controlling the opening and closing of the elevator door; an image processing part (6) for determining a detection area according to image signals of the camera device (5) and detecting articles to be detected. The safety elevator can make the detecting area size vary with the opening and closing of the elevator door.

Description

technical field [0001] The invention relates to an elevator equipped with a safety device at the elevator door as an entrance and exit, and is especially suitable for use in an elevator preventing passengers and luggage or rope-shaped foreign objects from being caught. Background technique [0002] It is known that in existing elevators, the door of the elevator entrance and exit is equipped with a sheet-shaped pressure-sensitive sensor that detects whether passengers and luggage are clamped by the elevator door, and is used to detect rope-shaped foreign objects similar to vacuum cleaner wires and When the door of the elevator entrance and exit is about to close, the photoelectric sensor of the passengers running into the elevator, etc., and by controlling the moment and speed of the elevator door opening and closing, to ensure that passengers can get on and off the elevator safely and smoothly. [0003] For example, a light-emitting part is set on the elevator door, and a l...
