针对当前较为突出的环境噪声污染问题,提出一种基于GPRS和虚拟仪器技术的环境噪声监测系统.该系统通过噪声提取等硬件电路将采集的噪声数据送到单片机进行声级的计算和显示,并通过GPRS模块以无线通信的方式将噪声波形发送到数据监测中心;监测中心接收数据后,利用labview软件对噪声信息进行存储和分析处理.整个系统的功耗低,具有较高的实用性和可靠性,将会成为环境噪声数据采集与监测的一种有效手段.
In view of the current more prominent environmental noise pollution, this paper proposes an environment noise monitoring system based on GPRS and virtual instrument technology, which sends the collected noise data to the singlechip to calculate and display the sound level through the hardware circuit such as noise extraction The GPRS module transmits the noise waveform to the data monitoring center through wireless communication. After receiving the data, the monitoring center uses labview software to store and analyze the noise information. The system has low power consumption, high practicability and reliability It will become an effective means to collect and monitor environmental noise data.
