基于STM32的图书馆人为噪音监测及告知系统

当前图书馆在实际开放状态下,不可避免地产生各种各样的噪音^1]。针对图书馆内部人为噪音的问题,设计一种基于STM32的图书馆人为噪音监测及告知系统,根据需要预设环境要求级别,实现及时告知并反馈给阅览室管理员方便管理。系统由主控模块,声音传感器模块、显示模块,蓝牙传输模块组成。实地测试表明,该系统可以更好地解决图书馆内人为噪音问题,提升人工管理的精确度和及时性。该系统经过调节告知程度,可以推广至其他需要安静的场合,在众多领域有很好的应用前景^2]。

A system about monitoring and informing man-made noise based on the research of STM32 in the Library

At present, there inevitably exists various noise in the libraries when they are openning. For this problem, we designed a system about monitoring and informing man-made noise based on the research of STM32. The system can adjust the level of alert according to datas defined by different levels of reminders that have been settled in advance, so it can remind the librarians to manage the situation in time. The system is consisted of the main control module, sound transducer module, display module and Bluetooth module. The field-testing results show that the system can solve the problem of the man-made noise in the library commendably and improve the accuracy and timelines of manual administration. Besides, the system can generalize to other places by adjusting the reminding level so it has excellent prospects in many fields.
