Problems solved by technology
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 elevator car Whether there are people in the room, it cannot be determined whether the volume is played and how to play it according to the situation of the person

The invention discloses an elevator advertising screen intelligent volume adjustment method and system. The embodiment of the method comprises the following steps of carrying out volume correction toobtain the magnitude of background noise and the volume interval; and carrying out intelligent volume adjustment, wherein the initial volume value is set on the basis of the background noise, the volume is adjusted according to the volume interval, and meanwhile, a volume correction module carries out correction at intervals to provide the benchmark for intelligent volume adjustment. According tothe elevator advertising screen intelligent volume adjustment method and system, intelligent adjustment on the volume of an advertising screen is implemented mainly through the image analysis technology and the voice frequency analysis technology; the image analysis technology includes a target detection technology and door state recognition; the number of people in an image is counted through target detection; according to door state recognition, a target detection manner is utilized as well, corresponding alarm and prompt labels are attached to the higher positions of an elevator door, and door state detection is implemented by detecting the position between the alarm and 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...
