摘要
基于虚拟仪器技术和CAN总线技术,设计了温室远程监控自动滴灌系统,分别对系统的硬件和软件做了说明。以STM32单片机为核心的CAN智能节点采集土壤湿度传感器的信号上传到LabVIEW监控平台,根据监控系统计算的结果和压力传感器的反馈信号驱动电磁阀完成滴灌工作。通过相关实验,结果表明系统能够实现滴灌过程的远程自动监控。系统硬件简单、可靠性高并且可以大大降低成本。
Based on virtual instrument technology and CAN bus technology,the greenhouse remote monitoring automatic drip irrigation system is designed.Its hardware and software are introduced,respectively.The CAN intelligent node with STM32 singlechip as the core collects the signal from soil moisture sensor and uploads it to the LabVIEW monitoring platform,then drives the electromagnetic valve to complete drip irrigation work according to the calculation result of LabVIEW monitoring system and the feedback signal from pressure sensor.Through the related experiments,the results show that the system can realize the automatic monitoring of drip irrigation process.The system has simple hardware,high reliability and can greatly reduce the cost.
