摘要
针对传统温室大棚参数监测存在繁琐的布线问题,设计了基于新型物联网技术的温室大棚智能监测系统。该系统以CC2530无线传输模块结合温湿度传感器、光照传感器和CO2浓度传感器构成无线采集节点,对温室环境参数进行检测;检测数据通过由ZigBee模块构成的路由节点选取最优路径实现数据的无线传输;采用STM32作为核心处理器设计嵌入式网关,并利用GPRS技术将现场检测到的数据实时传送给监测中心,实现对温室环境的实时监测和报警。结果表明,该系统运行稳定、测量准确、网络覆盖性好、布点灵活、低功耗并且使用方便。
Based on problems of complicated wiring with parameter monitoring in greenhouses,the new Internet of things of intelligent monitoring system in greenhouse was designed.CC2530 wireless transmission module for the system combined with the temperature and humidity sensor,light sensor and CO2 concentration sensor constituted the wireless acquisition node.The parameters of the greenhouse environment were tested.Testing data by routing nodes were used to select the optimal path to realize the wireless transmission.STM32 as core processor and GPRS technology were used to transmit the data to the monitoring center,realizing the real-time monitoring and alarm.The results showed that the system run stably with measurement accuracy,and had good network coverage with flexiblity,low power consumption and was easy to use.
