摘要
设计研究了用于环境数据采集的通用型多传感器无线节点,节点由传感器、单片机、无线通信模块、电源等组成,依据待测环境参数的不同可以更换合适的传感器。传感器输出信号经单片机存储与处理后经由Wi-Fi无线通信模块和其他节点组成星型网络拓扑结构的无线传感器网络系统,传至主节点综合处理,完成特定数据的采集。系统考虑了节点低功耗和Wi-Fi无线通信模块传输数据的安全性,选取USR-C322型号Wi-Fi模块与TRAMA通信协议,设定休眠模式,系统可以进行正常的数据传输。
Design of the universal multi-sensor wireless nodes for collecting environmental data,sensor nodes consist of sensor,microcontroller,wireless communication module,power supply and other components. According to the different environmental parameters,sensor can be replaced to find the appropriate sensor.Sensor output signal after single-chip computer storage and treatment via wi-fi wireless communication module and the other nodes of the star network topology of wireless sensor network system,comprehensive treatment to the master node,perform specific data collection.considering the low power of the system nodes and the security of the Wi-Fi wireless communication module,select the USR-C322 models of Wi-Fi module and communication protocols of TRAMA,setting the sleep mode, the system can be a normal data transmission.
