基于NRF24L01的嵌入式Linux大型场所盆栽自动浇灌系统

Automatic watering system for potted plant based on Linux and NRF24L01

针对目前大型办公楼、展览馆等大型场所大量盆栽花卉人工管理的现状,设计了一种基于NRF24L01的嵌入式大型场所盆栽自动浇灌系统。基于嵌入式Linux的QT系统设计了系统主控制平台,采用射频模块NRF24L01完成了无线传感网络的自组网设计,并基于STC12LE5A60S2微控制器设计一类通用性子节点,能完成盆栽花卉环境中空气温度、湿度、光照度与土壤湿度等参数的采集并发送到主控制平台,最后以QT图形的方式显示。一旦土壤湿度测量值比设定阈值低时MCU控制水泵对盆栽花卉自动浇灌。系统测试结果表明,自动浇灌系统工作稳定,性能良好,具有良好的推广价值。

According to current plant-management for large office buildings and exhibition halls, a plant management system is designed, which is based on NRF24L01. Based on QT of embedded Linux, the main control platform is designed. A RF module NRF24L01 is used for the wireless sensor network. Based on STC12LESA60S2 microcontroller, the child nodes is designed to collect temperature, humidity, ambient light and soil hygrometer. These data are sent to the main control platform and are displayed in QT. When the soil moisture of a plant is lower than the threshold value, MCU will control a pump to water it. Experiments show that the system works stable and performs well. And it has good promotional value.
