基于ZigBee的寒地水稻温室大棚智能控制系统设计

Zig Bee-based Rice in Cold Greenhouse Intelligent Control System Design

针对我国北方寒地水稻育秧大棚的结构特点,设计并开发了一套基于ZigBee的智能控制系统,并构建了该系统的星型网络,用以实现将传感器采集到的数据进行无线传输的功能。系统进行数据采集的模块分别采用AT89S52单片机、数字式空气温湿度传感器DB420、数字式土壤温度传感器DS18B20和数字式土壤水分传感器SM2802M,用这些模块来监测空气中的温湿度、土壤温度以及土壤水分等,将监测到的数据通过JM12864F显示出来。这些采集模块还可以监测到大棚内的空气温湿度、土壤温度、土壤水分含量等实时信息,并对这些信息进行分析处理,将分析处理的结果发送到用户手中,达到远程监控的目的。

According to the structural characteristics of cold rice seedling greenhouses, proposed and developed a ZigBee-based rice in cold greenhouse intelligent control system is constructed based on ZigBee star network, to achieve a wire-less transmission system for sensor data collected using AT89S52 microcontroller as the control for data processing, the use of digital air temperature and humidity sensor DB420 , digital temperature sensor DS18 B20 soil and soil moisture sen-sor SM2802M digital data acquisition to achieve the detection of air temperature and humidity, soil temperature and soil moisture,and through JM12864F display, in addition,the system can also monitor agricultural facilities on-site air tem-perature and humidity, soil temperature, soil moisture content, etc, and statistical analysis, to set upper and lower limits based on nursery temperature, ventilation and other motor control decision process and remote-control.
