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。
Aiming at the problem of receiving and transmitting instantaneous large data volume of wireless sensor nodes in harsh environment, a wireless sensor node design scheme based on dual-processor dual-frequency communication is proposed in this paper. Through the data acquisition and communication between nodes assigned to the processor function independently of each other, to improve the system capacity of instantaneous large amount of data processing. And proposes a communication scheme based on switching of different frequency bands. In a normal environment, a 2.4GHz high-frequency low-power frequency band is used, and in a specific environment, a 433MHz frequency band with strong adaptability is switched to ensure normal communication. In a large number of harsh environments transient high data volume simulation environment, the program has been excellent real-time data processing and communication capabilities.
