摘要
将无线传感器网络技术融入智能家居系统中,设计合理的网络节点成为智能家居系统的核心问题.在分析无线传感器网络节点结构基础上,提出以DSP芯片TMS320F206为处理器、AT86RF230为无线通信芯片的无线传感器网络节点.充分考虑节能和扩展性的需求,采用节点定时打开与关闭的协议且打开与关闭的时间比为1∶99.试验表明该无线网络节点能满足低功耗、长传输距离、准确定位、抗干扰的要求.
By applying wireless sensor network technology to smart home system, design of a rational network node is the key problem in smart home system. Based on the analysis of the architecture of wireless sensor networks nodes, wireless sensor networks nodes using DSP chip TMS320F206 mierocontroller and AT86RF230 transceiver are proposed. Considering the demands of energy saving and extensibility, a protocol of timely opening and closing is utilized and the time proportion is 1 ： 99. The wireless network node can satisfy the requirements of lowpower consumption, long transmitting distance, accurate localization and interference-resistance.
