STC89C52单片机迪文DGUS屏的教室环境监测系统的设计+电路图+程序

摘要经济发展必然伴随着污染，一些工厂产生的污染会影响学校的日常教学，有的甚至会直接影响学生的身体，造成难以想象的后果。因此人们希望智能教室提供的不仅是智能的控制，更是能创造并维持一个良好的学习环境，让学生处在安全舒适的环境中，以最佳的精神状态，取得最佳的学习效果。教室环境监测是构成智能教室重要的一环。因此我们需要在教室合理位置安装环境监测系统，以实现对各项卫生指标的实时监测。74901

为了满足更多人的需求，本文尝试设计一种使用迪文DGUS屏来显示和设置报警界限的教室环境监测仪。本课题所设计的教室环境监测系统，采用STC89C52单片机，主要包括温湿度监测、光强监测、CO2浓度监测、烟雾报警和触摸屏显示控制等部分。温湿度传感器、光照强度传感器、烟雾传感器及二氧化碳含量传感器这四类传感器分别用来采集教室环境参数，然后将采集的数据传送给单片机进行数据处理，单片机将控制继电器驱动门窗通风或灯光开闭，保证教室环境的正常维护；同时还能起到节约用电的效果，功能多样且节能环保，有实际应用的可能。

The design of the classroom environment monitoring system based on DGUS screen

Abstract Economic development is bound to be accompanied by pollution, the pollution some factories produced will affect the school's daily teaching, some will even affect the student's body directly, consequences are hard to imagine。 So it is hoped to provide intelligent classroom not only intelligent in control, but also can create and maintain a good learning environment, let the students in a safe and comfortable environment, keep a clear mind to achieve the goal of efficient learning。 Classroom environment monitoring is an important part of intelligent classroom。 Therefore, we need to install environmental monitoring system in the classroom, in order to realize the real-time monitoring of the health indicators。

In order to meet the needs of more people, this paper tries to design a classroom environment monitor which used DGUS screen to display and set the alarm limit。 The core of this design is STC89C52, mainly including temperature and humidity monitor, light intensity monitor, CO2 concentration monitor, smoke alarm and touch screen control, etc。。 Sensors are used to collecting data of classroom environment, and then the data will be sent to the microcontroller for data processing。 MCU control relay to driven the opening or closing of the doors, windows and lights, to ensure the normal maintenance of the classroom environment。 At the same time, it save electricity, functional persity and environmental protection, has practical application value。
