摘　　要：针对现有无线传感器网络(wireless sensor networks,WSN)环境监测终端设备采集环境参数较少、缺少现场形态信息、供电方式单一的不足,设计一种基于Zigbee的六参数低功耗智能采集终端.该终端配置有太阳能、市电和蓄电池的FILO(first in last out,FILO)三级堆栈智能电源,以及摄像头和多种传感器的传感器阵列.终端采用传感器阵列TDM(time division multiplexing,TDM)节能供电方案降低传感器阵列功耗,延长终端设备正常工作时间,符合现代化环境监测的要求.Aiming at the defects of the existing terminals in wireless sensor networks such as fewer environmental parameters,lack of morphological information of field and single power supply,a smart collection terminal with six-parameters and low power consumption is implemented.This terminal is configured with an intelligent power consisting of solar energy,mains and battery, camera and sensors array.Moreover,energy-saving power supply solution based on TDM is employed to help reduce energy consumption of the sensors array,so the working time of the terminals can be extended.
