Proteus模拟温室温湿度控制系统的实践教学

针对单片机课程实践环节薄弱的现状,以单片机典型案例"温室温湿度控制系统"为例,引入Proteus仿真软件作为课堂实践教学模式,设计了由AT89C52单片机、DHT11温湿度传感器、LCD1602、报警模块及控制模块组成的温湿度控制系统。温湿度上下限可人工设置,当超过阈值时对应的LED灯点亮、蜂鸣器报警,同时启动控制模块调节温湿度。通过Proteus仿真与课堂教学同步进行,克服了理论知识抽象的弊端,实现了理论与实践的高度融合,有利于学生创新性思维与动手能力的培养,为提高学生的学习积极性提供了便利条件。

Pratical Teaching of Greenhouse Temperature and Humidity Control System Based on Proteus Simulation

To improve the current situation of weak links between practice and classroom teaching of single-chip computer course,we took the classic case of single-chip computer"Greenhouse Temperature and Humidity Control System"as an example,and introduced Proteus simulation software as a practice teaching mode,a temperature and humidity control system was designed by composing AT89 C52 single chip computer,DHT11 temperature and humidity sensor,LCD1602,alarm module and control module.The upper and lower limits of temperature and humidity could be set manually,the corresponding LED lights was lit and buzzers alarmed when the actual value exceeded the thresholds,and the control module was activated to keep the temperature and humidity within the ranges.The synchronization of Proteus simulation and teaching not only overcomes the drawbacks of abstract theory,but also achieves high integration of theory and practice.It is beneficial to the cultivation of students’creative thinking and practical ability,and provides convenient conditions for improving learning enthusiasm of students.
