Abstract

The invention relates to a method, a device and a system for recognizing a stretcher mode in an elevator car. The method for recognizing the stretcher mode in the elevator car comprises the steps of when obtaining an overall depth image of various bearing objects in the elevator car, acquiring a geometric area and various pixel points of the overall depth image; selecting pixel points in a long edge direction of the geometric area from the various pixel points, obtaining a pixel point set, and acquiring depth data information of the pixel point set; recognizing a stretcher target area in the geometric area, and acquiring depth data information of the stretcher target area; acquiring a characteristic of the overall depth image according to the depth data information of the pixel point set and the depth data information of the stretcher target area; and when the characteristic of the overall depth image meets a stretcher mode depth image characteristic condition, determining and recognizing that the stretcher mode is different from a traditional elevator technology. According to the method, the device and the system for recognizing the stretcher mode in the elevator car provided by the invention, whether the elevator car is at a stretcher conveying state can be effectively recognized, and the implementation rate of a stretcher elevator is improved.

Description

technical field [0001] The invention relates to the technical field of elevator pattern recognition, in particular to a stretcher pattern recognition method, device and system in an elevator car. Background technique [0002] At present, there are relevant regulations on high-rise residential buildings. There should be no less than two elevators in each building, and one elevator that can accommodate a stretcher should be installed, hereinafter referred to as a stretcher ladder. [0003] During the implementation process, the inventors found that there are at least the following problems in the traditional technology: [0004] In the traditional technology, when a stretcher is put into the stretcher ladder, since the stretcher occupies most of the space in the car, the elevator generally does not enter a fully loaded situation. During the operation of the stretcher ladder, the car can be summoned by passengers on any floor, causing the car to respond to external calls durin...
