摘要
针对无线传感器网络(WSN)节点的能量有限的缺点,利用超低功耗MCU作为主控器件,采用工作模式和睡眠模式交替工作的软件协议,设计出低功耗的WSN终端节点.组网测试表明,该网络能正确组网,在3 V电源供电条件下,样机正常工作时发送电流小于15 mA,接收电流小于7 mA,休眠时电流小于65μA,实现低功耗设计目的.
A prototype of wireless sensor network terminal is designed based on the energy finitude characteristic. The hardware system consists of MSP430F149 ultra low power MCU and other correlative energy efficiency devices. Furthermore, the protocol adopts the sleep mode and awakening mode to alterative working for saving energy. At the end, network-building experiment performed shows that, with the 3 V power supply,the current of transmitting mode, receiving mode and sleep mode is less than 15 mA, 7 mA,65μA respectively.
