基于无线传感器网络的数据采集系统研究

Research of data acquisition system based on wireless sensor network

设计一种新的基于无线传感网络的数据采集系统,其由电源模块、无线模块和控制模块组成。电源模块为无线模块和控制模块提供电能,无线模块使用智能总线协议或低功耗射频协议从传感器中采集数据,控制模块利用MSP430F4250微处理芯片控制无线模块的采集工作,并对所采集到的传感器数据进行处理,处理后的数据将传回无线模块,用户通过控制模块设置数据交互标准,对无线模块中处理后的传感器数据进行提取。实验结果表明,所设计的系统拥有极小的采集误差和极低的无线通信误码率,较好地实现了设计目标。

A new data acquisition system based on wireless sensor network(WSN)was designed,which is composed ofpower supply module,wireless module and control module.The power supply module provides electricity for wireless moduleand control module.The intelligent bus protocol or low power radio frequency(RF)is utilized in the wireless module to collectthe data from sensors.MSP430F4250microcontroller chip is adopted in the control module to control the data acquisition andprocess the collected data from sensors.The processed data is delivered back to the wireless module.Users set data interactionstandard through the control module and extract the sensor data processed by wireless module.The experimental results showthat the designed system has little acquisition error and low bit error rate of wireless communication,has realized the designgoal almost.
