摘要
降水量是影响农作物产量和质量的重要因素之一,为了解决农业增雨的问题,设计了一套碘化银发生器远程控制系统。系统采用三层无线通信系统结构,核心器件采用4G网络技术的DTU和STM32F 103ZET6,DTU为远程数据传输器,STM32F103ZET6为现场设备控制器。两个DTU之间采用透传云的方式进行通信,STM32F103ZET6完成点火控制、拍照和图片回传等功能,现场图片回传采用分段转发的方式。实验证明系统从发送点火命令到焰条点火的时间小于5 s,现场图片回传在20 s内完成,能满足设计要求。现场采用太阳能供电,24 h不间断供电。系统具有高效、安全、稳定性高、实时在线、不受地理位置限制、适合大数据量的高速传输等优点,提高了人工影响天气的能力。
Precipitation is one of the important factors that affect crop yield and quality.In order to solve the problem of agricultural precipitation,a set of remote control system of silver iodide generator is designed.The system adopts a three⁃layer wireless communication system structure,and the core components adopt DTU of 4G network technology and STM32F103ZET6,DTU as the remote data transmission device,and STM32F103ZET6 as the field equipment controller.Passthrough cloud transmission is adopted for communication between the two DTU.STM32F103ZET6 completes functions such as ignition control,photo taking and image return,and field image return is segmented.The experiment proves that the system takes 5 s to send ignition command to flame strip ignition and 20 s to send back the scene picture,which can meet the design requirements.On⁃site solar power supply,24 hours uninterrupted power supply.The system has the advantages of high efficiency,safety,high stability,real⁃time online,not limited by geographical location,and suitable for high⁃speed transmission of large data,which improves the ability of weather modification.
