摘　　要：为解决机械设备无线振动监测网络存在的网络容量小、终端续航时间短问题,提出了一种基于MF-TDMA方式的低成本、低功耗网络设备设计方法。该方法使用SI4463作为无线传输通道,采用微控制器对网络频率和时间资源进行动态分配,采用休眠机制保证监测终端的续航能力。该方式组网灵活、网络规模扩充简单,可应用于多种低速无线传感网络中。In order to solve the problems in the wireless vibration monitoring network of mechanical equipment such as low network capacity and short endurance time,a low-cost and low-power consumption method based on MF-TDMA is proposed.The SI4463 is used as a wireless transmission channel,the network frequency and the time resources are dynamically allocated by using microcontrollers.The endurance of monitoring terminal is guaranted using dormancy mechanism.This method is flexible and simple in expansion of network scale,and can be applied to a variety of low-speed wireless sensor networks.
