Elevator sill detection method

Abstract

The invention discloses an elevator sill detection method. The method comprises the following steps: S1, carrying out data collection, wherein an elevator door image is analyzed from a video image; S2, carrying out data preprocessing and establishment of a sill detection model, wherein the elevator door image is preprocessed, and a sill in the elevator door image is marked and is input into a neural network for training to obtain a trained sill detection model; S3, carrying out network model detection, wherein the sill detection model is input into a control center module, and when a camera obtains a new video image, the sill detection model is used for predicting the opening and closing state of an elevator door in real time; and S4, judging whether the state of the elevator door is normal or not according to the prediction result, and giving out an alarm when abnormity occurs. By establishing the sill detection model, predicting the coordinate information of the elevator sill in real time and calculating the elevator operation parameters, the state of the elevator door is monitored in real time, problems can be found in time, and the elevator safety is improved.

Description

Technical field [0001] The present invention relates to the field of elevator technologies, in particular, to an elevator geodial detection method. Background technique [0002] At present, the detection of the obstacle of the elevator door is in the form of an infrared light curtain, and the infrared transmit tube and the infrared receiving tube are installed on the side of the elevator door. In the process of switching the door, if the infrared receiving tube does not receive an infrared signal It will illustrate that there is an obstacle, if you encounter a transparent object, you can't detect, a small object such as a dog, a child's little hand, or a part of the adults, its great probability is not detected, the test effect is very Poor, the puppy will happen outside, the owner enters the elevator, the elevator door is closed, and there is a safety accident. If the child's small hand or the part of the adult is on the side of the elevator door, the elevator does not detect th...

Problems solved by technology

[0003] Whether the elevator door is open or closed is also a very important consideration. Whether the elevator door is stable during the opening and closing process cannot be detected by the infrared light curtain. If the elevator door is opened or closed suddenly, people or objects will be caught, causing security incident
