摘要
简要介绍了ZigBee技术协议以及CC2420和MMA7260的性能和特点,设计了一种基于CC2420和MMA7260的无线传感器数据采集系统,给出了具体的软、硬件设计方法以及实际测试结果。该系统选用高灵敏度的三轴加速度传感器芯片MMA7260来采集机构的振动加速度信号,再通过支持ZigBee无线传输协议的CC2420把数据发送给接收装置。
This paper briefly introduces ZigBee protocol and the performance and characteristics of CC2420 and MMA7260.A wireless sensor data acquisition system based on CC2420 and MMA7260 is designed.Software and hardware designs are described,and test results are given.The system uses high-sensitivity three-axis acceleration sensor chip MMA7260 to collect the vibration acceleration signal,and then sends the data to the receiver by CC2420 which supports the ZigBee wireless protocol.
