Design of automatic monitoring data acquisition system for IoT intelligent wireless nodes
摘要
Abstract
The automatic monitoring data acquisition of wireless nodes under the environment of Internet of Things(IoT) can improve the capability of data detection and diagnosis analysis. Therefore,a dynamic gain control and DSP high-speed sig-nal processing based design method of automatic monitoring data acquisition system for IoT intelligent wireless nodes is pro-posed. During the overall design of automatic monitoring data acquisition system for wireless nodes based on the computer bus technology,two functional modules of DSP processor and PCI bus are designed. The sensor array of data acquisition is com-posed of multi-sensor information fused wireless monitoring nodes. The transceiver circuit and power amplifier circuit are de-signed to realize signal amplification and digital-to-analogue conversion(DAC)for data acquisition. The dynamic gain control method is used to achieve the amplification and filtering of data acquisition. The integrated design of automatic monitoring data acquisition system based on DSP signal processor is performed. The test results show that the system for automatic monitoring da-ta acquisition of IoT intelligent wireless nodes can realize over 15 MB/s continuous real-time data acquisition and recording, with the continuous data transmission rate of the bus higher than 20 MB/s,and the peak transmission rate higher than 33MB/s, which can meet the requirement of real-time recording of automatic monitoring data for wireless nodes.关键词
