摘要
针对农业大棚室内温度测量问题,提出了一种分布式无线测温网络的设计方案。网络主要由分布测温节点、大棚中继节点和监测主节点构成,基于ZigBee技术实现无线互连。分布测温节点的设计中选用DS18B20作温度传感器、AT89C51作控制核心;大棚中继节点采用嵌入式微控制器P89LPC913作主控MCU;ZigBee射频芯片选用CC2480。结果表明,该方案稳定可靠、科学可行,能够实现对大棚内温度参数的全方位监测。
To solve the temperature measurement of agricultural greenhouse,a novel distributed temperature measurement network was designed.The network was mainly divided into distributed measurement nodes,relay nodes and the master node.The nodes were based on ZigBee technology for wireless interconnection.The distributed measurement nodes were based on DS18B20 and AT89C51 chip.The relay nodes were based on P89LPC913 chip and CC2480 was selected as the chips of ZigBee.Experiment results showed that the network was stable and reliable,the all-round monitoring of the greenhouse temperature could be achieved well.
