摘　　要：针对环境噪声监测中多点声级数据采集以及实时传送的要求,提出了基于分组无线业务(GPRS)的新型环境噪声监测系统,实现环境声级数据的远程、快捷及低成本传输。提出了系统的总体设计方案,详细分析了系统的组网方案以及PPP网络连接和Socket编程等关键技术,实现了监测中心与监测终端之间的实时命令控制及数据传输,最后系统引进了低成本策略降低了使用成本,突破了系统的应用局限性,使该系统在环境噪声监测及控制领域具有良好的应用价值。For the requirements of multi-point measurement of environmental sound level and real-time transmission of data, a new noise monitoring system based on GPRS is designed to implement environmental sound level data of long-rang, low cost and fast delivery. First of all, the system program is proposed. Then a detailed analysis of the system＇s network program, PPP network connection and Socket programming, and the realization of the monitoring center to monitor the terminal through command control and data transmission are given. Finally a low- cost strategy is introduced to reduce the cost and to break through the limitations of the system. The system has a very good value in monitoring and controlling of environmental noise field.
