摘要
介绍了ZigBee技术的特点,对ZigBee的网络架构和原理进行了分析,应用CC2430作为控制核心,设计了基于ZigBee技术的路灯无线控制系统.详细介绍了系统的网络拓扑实现和硬件节点的设计方案,给出了相应的软硬件设计和组网算法,实现了路灯的无线网络控制.试验结果表明,在单协调器单节点组网时,组网用时20s,对l6个信道进行扫描节点的接入平均用时为150s.在室内10m左右距离的数据传输速率为250kbps;室外30～75m距离速率为40kbps,300m速率为20kbps.系统在发射状态下耗电为25.7mA,接收时为29.3mA,休眠状态下仅为2.5μA.
The characters of the ZigBee technology are introduced,and the network framework and principle of the ZigBee network are analysed. By applying to the CC2430 as the control core of control system, a street lamp wireless Control System is designed base on ZigBee technology. The network topology and hardware node design are mainly introduced. Based on the principle of the control system, the corresponding software and hardware design are proposed. The experimental results show that the network time is 20 s under the condition of single synchronizer single-node network; when scanning node to 16 channel, the average network time is 150 s. The data transfer rate is 250 kbps distance of around 10 m indoors. When outdoor at 30 -75 m distance, the rate is the 40 kbps, at 300 m distance the rate is 20 kbps. The system power consumption is 25.7 mA under the launching state, the power consumption is 29.3 mA under the receive state, the power consumption just is 2.5 μA under the dormant state.
