Description

Self-adaptive arrival clock

Technical Field

The utility model relates to the technical field of elevator equipment, in particular to a self-adaptive station clock.

Background

At present, an elevator arrival clock is generally prompted by adopting a voice station reporting mode to report the elevator arrival condition, and the problems of tone quality and volume exist in the application process. At present, the customization requirements on elevators in many high-grade communities, hotels and the like are very high, the elevators have good comfort, the audio-visual environment is also important, and even high-grade sound equipment is needed to be used as a stop reporting carrier. However, the environmental volume decibels of the places such as the district, the hotel and the like are always in variation, and passengers can feel uncomfortable when the current environment is quite quiet and the volume of the report station is too large. When the environment is very noisy, if the stop report volume is too small, the passengers can not hear the stop report content. Today's up-to-date clocks are typically supported by a fixed power horn. If the volume needs to be adjusted, the volume needs to be adjusted manually, but is difficult to be adjusted perfectly in the face of an environment with time variation.

In order to ensure the prompting function of the loudspeaker, the existing elevator manufacturer generally adopts high-strength sound output, and has only one strength, namely the loudspeaker has only one volume. Therefore, the volume of the loudspeaker cannot be controlled according to the running environment, so that passengers and the like can be frightened, unpredictable results are brought about, and in order to solve the problems, the application provides a self-adaptive standing clock.
