一种基于时分多址原理的新型无线采集网络

Wireless Acquisition Network Based on TDMA Principle

根据时分多址原理设计了一个用于小范围、大容量、低成本、低功耗等应用场景的无线采集网络。该网络通过主节点的广播信号进行全网校时,并由该广播信号触发数据的采集流程。每个节点设备在各自的通信时段内进行数据传输,互不干扰。节点设备通过自身的RX8025T实时时钟芯片在全温区进行时钟校正,保证节点设备时钟在不同温度下的时钟精度。

According to the TDMA principle,a wireless acquisition network for small area,large capacity,low cost and low-power consumption is designed.The network performs the whole network calibration through the broadcast signals of the main node,and the data acquisition process is triggered by the broadcast signal.Each node device carries out data transmission in its own communication time interval without interfering with each other.The node device performs clock correction in the full temperature region through its own8025 Treal-time clock chip,that ensures the clock accuracy of the node device clock at different temperatures.
