摘　　要：为了解决噪声的长期、在线测试,设计了一个基于无线传感网络的噪声测试系统,可实现噪声数据的多点在线采集和实时处理。噪声数据可在无人值守的测试节点获得,并通过无线传感网络传送至数据中心。数据经过处理计算后,将给出各类特征数据和数据曲线。经过调试完成的系统是一套完整的嵌入式应用系统,包含嵌入式硬件平台、嵌入式操作系统、噪声数据测试和传输系统。该系统可广泛应用于噪声测试或需要长时间进行噪声监测的场合。In order to solve the measurement of noise in a long term and on line way, the noise-measuring system based on Wireless Sensor Networks is designed. It can be used to collect and process noise data in multiple measuring-points. Noise data can be collected at the unattended measuringpoints, and transmitted to the data center. After data processing, it will get the result of the noise. It is an embedded system including embedded hardware, embedded operating system, noise data-measuring and transport system. An application of the noise-measuring system validated that it is widely used in some applications which need to measure noise data in a period of time.
