基于STM32单片机的环境噪声实时监测系统

Environmental Noise Real-time Monitoring System Based on STM32 Microcontroller

目前,环境噪声污染已经成为影响居民健康的主要因素之一。针对某居民小区周边环境的噪声污染开展研究,进行实时监测和判别。采用STM32F103C8T6单片机作为微处理器,通过噪声传感器检测目标参数,在有机发光二极管(Organic Light-Emitting Diode,OLED)显示屏上实时显示检测到的噪声值。经多次实践检测可知,该系统能够实时监测城市某一居民区域的噪声污染源,并将污染源超限信息上报有关人员进行处理,有效减少环境噪声污染对居民身心健康造成的影响。

At present,environmental noise pollution has become one of the main factors affecting residents’health.In this paper,the noise pollution of the surrounding environment of a residential area is studied,and the real-time monitoring and discrimination are carried out.STM32F103C8T6 microcontroller was used as the microprocessor,the target parameters were detected through the noise sensor,and the detected noise value was displayed in real time on the Organic Light-Emitting Diode(OLED)display screen.After several practical tests,it can be seen that the system can monitor the noise pollution source in a certain residential area in real time,and report the information of pollution source exceeding the limit to relevant personnel for processing,effectively reducing the impact of environmental noise pollution on the physical and mental health of residents.
