摘要
为提高农业大棚种植效率、减少管理成本,设计了远程监控系统,用于对温湿度、光照强度、土壤电导率和盐度等农作物生长环境参数进行监控.本地端以STM32单片机为核心,使用Modbus-RTU协议对大棚内部环境参数进行采集,根据传感器返回的数据以一定决策通过控制继电器的方式使大棚内部的环境参数维持在适合农作物生长的范围内,同时系统可实现自动/手动切换控制.以RGB触摸屏为交互界面,使用ESP8266与远端(PC机)进行通信.远端使用QT开发平台实现对大棚内部环境参数的远程监视.经过软硬件测试,系统具有安全、稳定、低成本等优点,可以保证大棚内部的环境维持在适合作物生长的水平.
In order to improve the planting efficiency of greenhouse agricultural produce and reduce the management cost,a remote monitoring system is designed to monitor the environmental parameters of crop growth:temperature and humidity,light intensity,soil conductivity and salinity.The local terminal takes STM32 MCU as the core,uses Modbus RTU protocol to collect the internal environmental parameters of the greenhouse,makes a certain decision according to the data returned by the sensor,and controls the relay to maintain the internal environmental parameters of the greenhouse in a range suitable for crop growth.The system can be switched automatically/manually at the same time.RGB touch screen functions as the interactive interface;ESP8266 is used to communicate with the remote terminal(PC);QT development platform is set up to realize the remote monitoring of the internal environmental parameters of the greenhouse.Results of software and hardware testing show that the system has the advantages of safety,stability and low cost,which can ensure that the internal environment of the greenhouse is maintained suitable for crop growth.
