Elevator car video talkback control method based on machine vision technology and elevator cloud central control platform

Abstract

The invention discloses an elevator car video talkback control method based on a machine vision technology and an elevator cloud central control platform. A video talkback terminal extension is installed in an elevator car, a video talkback terminal host is installed in an elevator security room, when an elevator talkback person sends a video talkback request through the video talkback terminal extension, according to the sending duration of the video talkback request, the video talkback request is responded in a grading mode, the timeliness of responding to the video talkback request is improved, and therefore after the video talkback request is responded by elevator security personnel, the video talkback picture and the audio volume are regulated and controlled in real time, the intelligent comprehensive control of the elevator car video talkback is realized, the control function of the video talkback terminal in a current elevator car is perfected, the intelligent level, the flexibility and the humanization degree of the video talkback terminal control are improved, the video talkback experience feeling of a user is enhanced, and the personal safety of personnel in an elevator is timely guaranteed.

Description

technical field [0001] The invention belongs to the technical field of elevator monitoring and control, and in particular relates to an elevator car video intercom control method based on machine vision technology and an elevator cloud central control platform. Background technique [0002] In recent years, with the increase in the number of high-rise buildings, the application of elevators has become more and more common, and there have been more and more elevator safety accidents. Communication, in this case was born the elevator video intercom system. By installing a video intercom terminal extension in the elevator car and a video intercom terminal host in the elevator security room, when a safety accident or other situation occurs in the elevator, the person in the elevator sends a video intercom request according to the video intercom terminal extension, The video intercom terminal host receives the video intercom request, and thus establishes an intercom call. The el...

AI Technical Summary

Problems solved by technology

[0004] 1. Most of the equipment settings in the video intercom terminal extension are fixed, such as the camera angle and the volume control of the speaker, which cannot be adjusted according to the actual height of the intercom personnel in the elevator car and the noise loudness in the elevator car. The situation is adjusted in real time, resulting in insufficient flexibility of video intercom display screen and audio volume control, resulting in poor video intercom effect;

[0005] 2. The timely response to the video intercom request is not enough. When the elevator intercom personnel send a video intercom request but the intercom request has not been responded for a long time, the elevator intercom personnel can only passively wait for the intercom request to be responded. In this case Under the circumstances, the personal safety of the personnel in the elevator cannot be guaranteed in time

[0006] To sum up, it can be seen that the current video intercom control function in the elevator car has a low level of intelligence, insufficient flexibility, and lack of humanized control, which reduces the user's video intercom experience.
