基于485总线和虚拟仪器的智能农业监控系统设计

针对传统农业监控系统的不足,为了高效利用农业资源及实现智能农业,设计了一种基于485总线与LabVIEW的智能农业监控系统。选用Arduino控制器作为下位机,以PC机为上位机,两者通过RS-485总线实现通信。系统能够对农作物生长环境系统中的温湿度、光照强度、土壤水分、CO2浓度等参数进行监控；当监控参数超限时,能够自动控制相关设备进行自动调节,从而确保农作物处于适宜的生长环境。该系统具有性价比高、扩展性强等优点,具有一定的推广应用价值。

Design of intelligent agriculture monitoring system based on 485 bus and virtual instrument

In view of the deficiency of the traditional agricultural monitoring system, a kind of intelligent agriculture monitoring system based on 485 bus and LabVIEW is designed in order to utilize the agricultural resources and realize intelligent agriculture efficiently. Arduino controller as the next bit machine, PC machine as the host computer, both through the RS-485 bus to achieve communication. System can on crops growth environment system of temperature and humidity, light intensity and soil humidity, CO2 concentration parameter monitoring; when the monitoring parameters overrun to automatic control equipment of automatic adjustment, so as to ensure that the crop is in a suitable environment for the growth. The system has the advantages of high cost performance, strong expansibility, and so on. It has certain value of popularization and application.
