摘要(Abstract)：

在物联网环境下进行无线节点自动监控数据采集,提高数据检测和诊断分析能力,提出基于动态增益控制和DSP高速信号处理的物联网智能无线节点自动监控数据采集系统设计方法。基于微机总线技术进行无线节点自动监控数据采集系统的总体设计,系统主要包括DSP处理器和PCI总线两大功能模块设计,数据采集的传感器基阵由多传感信息融合的无线监测节点组成,设计收发转换电路和功率放大电路实现采集数据的信号放大和数/模转换。采用动态增益控制方法实现采集数据的放大和滤波处理,基于DSP信号处理器进行自动监控数据采集系统的集成设计。测试结果表明,采用该系统进行物联网智能无线节点自动监控数据采集,能实现持续的大于15 MB/s的实时数据采集和记录,总线持续数据传输速率超过20 MB/s,峰值传输速率也可超过33 MB/s,满足实时记录无线节点自动监控数据的需求。
