Abstract

The invention provides a silence reminder for a library. The silence reminder comprises a plurality of decibel meters, a single-chip microcomputer, an LED (light-emitting diode) display screen and a plurality of warning devices, wherein each decibel meter is arranged at a corresponding position of each seat of the library and is used for collecting sound signals at the corresponding seat of the library, converting the sound signals into electric signals and transmitting the electric signals and corresponding seat information of the library to the single-chip microcomputer; the warning devices are in one-to-one correspondence with the decibel meters, and each warning device is distributed at the corresponding position of the corresponding decibel meter; the single-chip microcomputer is used for controlling the displaying of the LED display screen according to the electric signals received from the decibel meters and controlling the start and stop of the corresponding warning devices according to the electric signals received from the decibel meters.

Description

technical field [0001] The invention relates to a library quiet reminder. Background technique [0002] In a place like the library, which should be quiet, the most annoying thing for students who study hard is the couple or classmates who talk loudly next to them. However, noise makers often do not intentionally make loud noises, but because they do not realize that their voices have disturbed others. [0003] Prior art ignores such small-scale sound decibel reminding devices as libraries. Moreover, the existing sound decibel reminding device has a complicated processing method. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a kind of [0005] In order to achieve the above-mentioned technical purpose, according to the present invention, a kind of library quiet reminder is provided, and it comprises: a plurality of decibel meters, single-chip microcomputer, LED display screen and a plurality of warning device...
