【摘要】 为提高远程分散多点监控系统各点监控的实时性,降低成本,扩展监控距离,适应各种复杂工况,节省人力资源,设计出一种新型的基于GPRS网络和ARM架构的远程数据采集系统。通过ARM和SIM900A的GPRS模块构成的无线数据传输节点与已普及的移动通信网结合的组网方式完成数据采集、汇总、上传及远程监控。实验表明,该方案具有很好的实时性与可靠性。从实际应用出发,把这个数据采集系统应用于数字水印系统当中,通过GPRS网络把水印数据传输到服务器,服务器也可以通过GPRS网络对水印系统进行控制。更多还原

【Abstract】 In order to improve remote distributed multi-point monitoring system’s real-time performance,reduce costs,extend monitoring distance,adapt to various complex conditions and save human resources,it designs a new remote data acquisition system based on ARM architecture and GPRS network.These wireless transmission nodes consisted of ARM and SIM900 A could connect to the mobile communication network and accomplish the collection,aggregation and upload of data.Experimental results show that this scheme has a good real-time and reliability.Moreover,it puts the data acquisition system into watermarking system and accomplishes the data transmission and system control.更多还原
