温室环境无线监测系统的设计

Design of Wireless Monitoring System of Greenhouse Environment

为实现温室环境的远程监测与控制,设计了一套温室环境无线监测系统.该系统可用于监测温室内空气温度、相对湿度和太阳光照度等环境因子.以Mica2节点为核心,设计了系统中各个节点的硬件电路.数字传感器SHT11和TSL2561分别用于检测环境温湿度和光照度.在节点软件设计中采用ACK机制保证了良好的无线通信质量.采用软件看门狗提高了系统抗干扰性能.将该系统应用于一座玻璃温室进行了现场试验,结果表明系统运行稳定可靠.

In order to monitor and control the greenhouse remotely,a wireless system of monitoring the environmental factors in greenhouse was designed,which could be used to monitor the air temperature,relative humidity and illumination intensity.The hardware of all the nodes in the wireless system was designed with the Mica2 nodes as the core.Both the digital sensors SHT11 and TSL2561were adopted to monitor the temperature and relative humidity and illumination intensity respectively.The ACK mechanism was used to guarantee the good wireless communication quality in the software design.The software watchdog was used to improve the anti-interference performance.The operation of the system indicated that it could run stably and the ACK mechanism could guarantee good wireless communication quality.
