Design and Implementation of Environmental Noise Monitoring System Based on GPRS
Yuan Xiao-xiong · Audio Engineering · 2008
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 lowcost 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.
