摘　　要：针对恶劣环境下无线传感器节点所面对的瞬时大数据量接收和发送这一课题,本文提出一种基于双处理器双频通信的无线传感器节点设计方案。通过将数据采集及节点间相互通信分配到功能相互独立的处理器,来提高系统对瞬时大数据量的处理能力。并提出一种基于不同频段切换的通讯方案,在普通环境下使用2.4GHz高频低能耗频段,而在特定环境下切换至适应能力强的433MHz频段以保证正常通信。在大量恶劣环境下瞬时高数据量的仿真环境中,该方案得到了极佳的实时数据处理能力及通信保持能力。This paper proposes a scheme about wireless sensor node based on dual- processor and dual - band communication, which aims at instantaneous large amount of data receiving and sending in harsh environment. Processor of function independence will respectively control data acquisition and node communication to improve instantaneous large amount of data processing capacity. And a different bands witch based communication scheme is proposed. This scheme uses 2.4GHz high - frequency low -energy band in conventional environment and 433MHz in specific environment to ensure normal communication. When instantaneous large amount of data is simulated in harsh environment, our scheme shows the best performance of real - time data processing and communication.
