Problems solved by technology

[0002] At present, with the improvement of people's quality of life, people have higher and higher requirements for regional sound decibel control. In many quiet areas, there are signs of "no whistle" or "please keep quiet". If you don't obey the regulations, still honk or talk loudly, the area manager can't warn the violators who make noise in time, thus causing troubles to people's lives

Abstract

The invention relates to an embedded system of monitoring decibels in real time, and belongs to the automatic control field. The embedded system of monitoring decibels in real time includes a singlechip, a microphone, a camera module, a key module, a liquid crystal display screen, LED indicating lamps, a network communication module and a PC, wherein the microphone sends acquired sound signals through A / D conversion to the inside of the singlechip; the singlechip carries out comparison and determination according to the decibel value set by the key module, and displays the decibel value of the sound on the liquid crystal display screen; the singlechip emits a control signal to control the LED indicating lamps to flicker and control the camera to take pictures; and the liquid crystal display screen displays acquired pictures, and uploads the acquired pictures to the PC to store in the network communication mode. The embedded system of monitoring decibels in real time can give a prompt to a violator who makes noise, and then gives an alarm to the violator in the mode of taking pictures, and punishes the violator by monitoring mute areas in real time.

Description

technical field [0001] The invention relates to an embedded system for monitoring sound decibels in real time, belonging to the field of automatic control. Background technique [0002] At present, with the improvement of people's quality of life, people have higher and higher requirements for regional sound decibel control. In many quiet areas, there are signs of "no whistle" or "please keep quiet". If you don't follow the regulations, still honk or talk loudly, the area manager can't warn the violators who make noise in time, which will cause troubles to people's lives. Contents of the invention [0003] The technical problem to be solved by the present invention is: the present invention provides an embedded system for real-time monitoring of sound decibels, with STM32 single-chip microcomputer as the control core, real-time monitoring of sound decibels in silent areas, and violators are punished by flashing LED indicators. Prompt, and warn violators by taking photos a...
