摘要
针对农作物长势对现有温室无线监控系统的通讯干扰问题,设计基于ZigBee技术与WiFi技术的北方日光温室群监控系统。cc2530作为主控芯片,结合加入功率放大模块,配置双天线等方法,目的在于解决ZigBee与WiFi在2.4GHz下通讯冲突,并提出应用于北方日光温室群的思路,解决了当前系统只能应用于单个温室的局限性问题,实现区域性多温室监控的目的。经测试,对冲突干扰及作物生长的通讯丢包率进行采集,数据通讯丢包率为1.85%。
Aiming at the interference of communication by the crops growth status in the northern greenhouse,the new monitoring and controlling system based on ZigBee and WiFi in the northern sunlight greenhouse group was designed.Using cc2530 as the main control chip,adding the power amplifier module,equipping the dual optional antenna and other methods,it was aimed to solve the interference between the ZigBee and WiFi,and provided the thought of applied in the sunlight greenhouse group,solved the limitation of current system can only be applied to a single greenhouse,and achieved regional multi-greenhouse monitoring.By testing in the sunlight greenhouse,the packet loss rate of the interference of communication and corps growth status were analyzed,which the packet loss rate is 1.85%.
