摘要
以监测环境噪声为目的,设计了对噪声统计声级(LN)、等效连续声级(Leq)、噪声污染级(Lnp)、交通噪声指数(TNI)、昼夜等效声级(Ldn)、标准偏差(SD)等常用噪声评价量进行测量、存储、统计、分析的噪声监测系统.给出了其设计方案、原理框图及软件流程图,并着重介绍了主要硬件电路、程序模块的设计与实现,实验证明,该系统工作正常,达到了预期的设计目标.
To monitor environment noise, are try to design an intelligent noise monitoring system which can measure, store, calculate and analyze the common noise rating quantity, such as LN, Leq, Lap, TNI, Ldn, SD and so on. The design proposal, block diagram and the software flow pattern are written in this paper, which also focus on the design and realization of the main hardware circuit and the functions of software. At the same time, the experiment proves that the instrument works well and achieves the expected design objective.
