摘要
介绍了温室中无线传感器网络的组成及其工作过程,采用基于ARM CortexTM-M3的LMS3S1968微控制器和无线收发芯片nRF905设计了执行器节点。从硬件和软件两个层面进行研究,根据无线通信系统特点设计了系统的硬件、软件,并进行了调试和试验运行;采用μC/OS-II嵌入式实时操作系统作为无线传感器网络节点的操作系统。系统具有可靠性高、可方便扩展通信节点容量等优点。
The ccomponent and of the greenhouse wireless sensor network was introduced, as the same time, its working process was presented. The actuator nodes were designed based on ARM CortexTM-M3 LMS3S1968 microcontroller and radio transceiver nRF905. The hardware and software of the actuator nodes were studied, and according to the wireless communication system characteristic designing the system of hardware and software. The system was also debugged and test run. The embedded real-time operating system of μC/OS-II was utilized as wireless sensor network perating system. The system was high reliability and expansibility.
