摘要
为避免霜冻和冰雹天气对山地苹果生长的不利影响,文中设计了一种基于STM32F417IGT6的智能灾害防护系统。采用软硬件结合的方法,以STM32F417IGT6单片机为主控芯片,通过DHT11数字温湿度传感器获取天气信息。该系统以ESP8266进行无线通信,分别对霜冻、冰雹天气设计相应的防护措施,使得用户可以在霜冻、冰雹天气来临前及时采取应对措施,提高苹果产量。样机的实地测试和实验数据表明,系统可以提前20 min对用户发出预警,并在2 min内完全启动防护装置,具有成本低、响应速度快、防护功能强的特点,有较高的应用推广价值。
In order to avoid the influence of frost and hail on the growth of apple,an intelligent disaster prevention system based on STM32F417IGT6 is designed.The system adopts the method of combination of software and hardware,with STM32F417IGT6 as the main control chip,and obtains weather information through DHT11 digital temperature and humidity sensor.In addition,the system uses ESP8266 for wireless communication,and corresponding protection measures are designed for frost and hail weather.The designed system allows users to take timely countermeasures before the arrival of frost and hail to increase apple production.The field test and experimental data of the prototype show that the system can give an early warning to the users 20 minutes in advance,and fully start the protective device within 2 minutes,which has the characteristics of low cost,fast response speed and strong protective function,and has high application and promotion value.
