A method and system for adjusting intelligent volume of an elevator advertising screen

Abstract

The invention discloses a method and system for intelligent volume adjustment of an elevator advertising screen, wherein the method embodiment includes the following steps: performing volume correction to obtain background noise size and volume interval size; performing intelligent volume adjustment, setting an initial volume value based on the background noise, The volume is adjusted according to the volume interval, and at the same time, the volume correction module performs corrections at regular intervals to provide a benchmark for intelligent volume adjustment. The invention mainly realizes the intelligent adjustment of the advertising screen volume through image analysis and audio analysis technology. Image analysis technology is mainly target detection technology and door status recognition, through target detection to identify the number of people in the picture. Door status recognition also uses the method of target detection. The upper position of the elevator door will be affixed with corresponding alarm prompt labels, and the door state detection is realized by detecting the position between the alarm prompt labels.

Description

technical field [0001] The invention belongs to the technical field of data analysis, and in particular relates to an intelligent volume adjustment method and system for an elevator advertising screen. Background technique [0002] At present, the automatic adjustment of the volume of the advertising screen in the elevator is realized by setting different volumes at different time periods. The original design intention is that different time periods are closely related to people's daily life, so different volumes are set to meet the requirements. This method only adjusts the volume through time, and the device cannot fully perceive the car situation, so the effect and experience are not good. The above setting methods cannot solve two problems. First, the volume reference and volume adjustment interval of the elevator car equipment. Due to the aging of the equipment or the noise of the place, the volume adjustment needs a reference and its adjustment interval; second, the el...
