摘要
基于TI公司的第二代SoC芯片CC2530和FPGA,构建了多信道的无线传感器网络实时采集系统。采用延迟测量时间同步机制DMTS和TDMA保证了网络的时间同步及数据的可靠传输;利用FPGA实现的多路并行独立SPI接口控制各个基站,通过USB接口与外部连接来采集数据。经实际验证,该系统可以准确、实时地将监测信息上传至控制中心。
A multiple channel WSN continuous real-time data acquisition system is implemented based on TI＇s the second generation sys- tem on chip CC2530 and FPGA. DMTS and TDMA mechanism of delayed-measurment time synchonization ensure network time syn- chonization and reliability transmission of data. An independent multi-channel SPI interfaces in FPGA control the base stations respec- tively,then tranfer sensor data through USB interface. The system architecture is verified by practical experiments. It turns out that all nodes can sample monitoring message precisely and transfer it to control center.
