| 摘 要： | 设计并实现了基于嵌入式系统和GPRS无线数据网络的分布式噪声与振动检测系统,描述了系统体系结构、硬件框图和软件系统架构。该系统利用ARM处理器S3C2410作为核心处理器,依靠DSP协处理器中的软件算法实现声振信号的声级计算、频谱分析和噪声统计分析,在单个设备上集成了多种声振分析功能。同时,GPRS模块为系统提供了分布式声振检测能力,可以在一个监控中心就完成整个城市或区域的声振监控和研究工作。

| Abstract: | A scheme to implement a sound and vibration detecting system based on embedded system and GPRS network is presented. The high-level system architecture is put forward and the design of hardware and software workflow is given. ARM 9 RISC CPU S3C2410 is used in the embeded system as its core processor and DSP is used as its co-processor which integrates the sound level, noise spectrum analyzer and noise statistical analyzer into a single device by DSP algorithm. In addition, GPRS module to access GPRS network which provides distributed detecting and study of noise and vibration in a area even the whole city is used. |
