摘要
根据ZigBee的堆栈协议,建立了一个小型星状网络系统,设计了一种基于ZigBee的温湿度监测系统。系统终端节点以ATMEGA16L为内核,以一体化的温湿度传感器SHT111为采集设备,使用专用的ZigBee传输模块CC2420。主节点以ATMEGA16和CC2420分别作为主控部分和传输芯片,采用液晶12864,计算出终端节点测量的温度、湿度值并显示在液晶屏上。通过适当的软、硬件抗干扰处理,设计出的多点无线温湿度采集系统具有实用性、小型化等特点。
Based on the protocol of ZigBee, establishing a new star network system and creating a monitoring system under the agreement, the network system, using the integrated temperature and humidity sensor SHT11, sampling each terminal node to calculate the temperature, humidity and displayed on the LCD screen. ATMEGA16L is used as system terminal node eore、 SHTll for the acquisition equipment, a professional ZigBee transmission module CC2420. ATMEGA16 and CC2420 also were used as the master part and the transfer tool, combined with LCD 12864. Through appropriate software and hardware anti-jamming processing, make this system more pratical.
