Classroom environment control system

Abstract

A classroom environment control system relates to the technical field of environment monitoring. A temperature sensor, a carbon dioxide concentration sensor, an illumination intensity sensor, a liquid crystal screen, a fluorescent lamp, a buzzer, a relay, an infrared diode, and a light emitting diode are connected to a logic control circuit; a power source supplys electricity to the logic control circuit; the logic control circuit reads a temperature value of the temperature sensor, compares the temperature value with a preset value, controls starting or stopping of an indoor air conditioner through the infrared diode, or controls starting or stopping of an indoor fan through the relay; when the logic control circuit detects the fact that the carbon dioxide concentration is higher than a preset value, the buzzer is started, the liquid crystal screen displays an alarm state so as to prompt windowing and air-exchange; and the illumination intensity sensor detects the current illumination intensity, and controls the brightness of the fluorescent lamp in real time. The classroom environment control system can intelligently control a classroom environment, can achieve an optimized effect of the classroom environment, is beneficial to physical and mental health of students, can improve the leaning efficiency of the students, and can save energy and protect an environment.

Description

technical field [0001] The invention relates to the technical field of environment monitoring, in particular to a classroom environment control system. Background technique [0002] The classroom is the main learning place for students, and students spend most of their day in the classroom. The temperature, light intensity and carbon dioxide concentration in the classroom are all affecting students' health and learning efficiency. For example, if the temperature is too high, people will feel drowsy, which will affect the efficiency of listening to lectures, and even cause heat stroke; if the temperature is too low, it will cause frostbite to the hands and feet, which will affect the flexibility of hands and distract students during exams and homework, resulting in low learning efficiency for students. . In order to keep the classroom warm in winter, close the doors and windows. At this time, the concentration of carbon dioxide in the classroom will increase, which will not...

Problems solved by technology

For example, if the temperature is too high, people will feel drowsy, which will affect the efficiency of listening to lectures, and even cause heat stroke; if the temperature is too low, it will cause frostbite to the hands and feet, which will affect the flexibility of hands and distract students during exams and homework, resulting in low learning efficiency for students.

In order to keep the classroom warm in winter, close the doors and windows. At this time, the concentration of carbon dioxide in the classroom will increase, which will not only lead to insufficient oxygen supply to the brain of students, low learning efficiency, but also affect physical health
