农业温室大棚环境智慧监测系统设计

温室大棚作为重要的农业设施,对于我国的农业甚至全球农业具有重大的意义,而温室大棚的温度、湿度的监测与控制是关键问题。文章设计了农业温室大棚环境智慧监测系统,使用了STC89C52单片机作为下位机的主控芯片,DS18B20检测大棚内的温度,YL-69检测大棚内土壤湿度,用LCD1602显示温湿度与温湿度的上下限,通过ZigBee无线通信技术将温度上传至Labview上位机,并在上位机上绘制温度、湿度的变化曲线。若温度超越上下限时,控制顶膜的打开或者闭合,在湿度超越上下限时,控制水泵工作,同时通过报警来提醒工作人员。通过测试,本系统满足实际需要,具有广泛的推广价值。

As an important agricultural facility,greenhouses are of great significance to my country's agriculture and even global agriculture.The monitoring and control of temperature and humidity in greenhouses are key issues.This paper designs a wireless monitoring system for agricultural greenhouse environment,using STC89C52 single-chip microcomputer as the main control chip of the lower computer,DS18B20 detects the temperature in the greenhouse,YL-69 detects the soil humidity in the greenhouse,and LCD1602 displays the upper and lower limits of temperature,humidity and temperature and humidity,uploads the temperature to the Labview host computer through ZigBee wireless communication technology,and draws the change curve of temperature and humidity on the upper computer.If the temperature exceeds the upper and lower limits,control the opening or closing of the top film.When the humidity exceeds the upper and lower limits,control the pump to work,and at the same time,alert the staff through an alarm.Through the test,the system meets actual needs and has a wide range of promotion value.
