针对传统分布式数据采集系统在传输过程中存在的瓶颈,提出了基于GPRS无线网络的数据采集传输系统的设计方案,该系统采用了高精度24位AD芯片采集数据,经过高性能16位数字信号控制器dsPIC4011对数据进行分析处理,然后通过GPRS模块传输至服务器,从而实现对外界数据进行实时监控。系统性能稳定可靠,在水文、地质、交通等领域具有广阔的应用前景。 Aiming at the bottleneck of traditional distributed data acquisition system in the process of transmission, a design scheme of data acquisition and transmission system based on GPRS wireless network is proposed. The system uses high-precision 24-bit AD chip to collect data and high performance 16-bit digital signal DsPIC4011 controller for data analysis and processing, and then transmitted to the server through the GPRS module, in order to achieve real-time monitoring of external data. System performance is stable and reliable, in the hydrology, geology, transportation and other fields have broad application prospects.
