監測教室環境的集散式網絡監控系統,各傳感器檢測到的教室的溫度、濕度、光強、二氧化碳濃度、噪聲強度的數據發送給單片機,單片機根據所采集的信息進行分析判斷,當超出設定

摘要教室是學習的場所,老師和學生受教室環境的影響比較大。而很多事件會對教室的環境造成影響,如一些教室的施工會造成噪音的污染、夏季或者冬季溫度會過高或過低、人多的時候容易造成二氧化碳的濃度升高,這些都給日常的教學活動帶來了負面影響。長此以往,教室的環境并未受到足夠的重視,而由教室環境比較差帶來的影響長期影響著中小學甚至高校的上課效率。如果用基于單片機的集散式網絡監控系統對這些參數進行監控,并在超出范圍的時候進行報警,基于這些信息采取相應的措施,對相應的參數進行控制,可以有效的改善教室的環境,提高課堂質量,具有非常重要的意義。35838
本設計是一個用于監測教室環境的集散式網絡監控系統,各傳感器檢測到的教室的溫度、濕度、光強、二氧化碳濃度、噪聲強度的數據發送給單片機,單片機根據所采集的信息進行分析判斷,當超出設定數值后,發出聲光報警。本設計所使用的傳感器有溫濕度傳感器,光強傳感器,二氧化碳傳感器,噪聲傳感器,均為數字傳感器。傳感器模塊已經集成了傳感器和相關電路,可以直接把測量的數據作為單片機的輸入信號,再通過單片機對所得到的信號進行處理,然后通過顯示模塊顯示相應的測量值。下位機由與溫濕度傳感器,光強傳感器,二氧化碳濃度傳感器和噪聲傳感器連接的單片機構成,每個教室對應一個下位機,所以存在很多個下位機,上位機對多個下位機進行監控。

Abstract The classroom is a place for learning, teachers and students under the influence of classroom environment is larger. While many events will affect the environment of the classroom, as some of the construction of the classroom can cause noise pollution, summer or winter temperature too high or too low, men were more likely to cause increased concentration of carbon dioxide, these are brought negative influence to the daily teaching activities. In the long term, enough attention has been given to the environment of the classroom, and by the effects of classroom environment more bad affects the efficiency of primary and secondary schools and even universities in class for a long time.If with centralized-distributed network monitoring system based on single chip microcomputer to monitor these parameters, and call the police, when beyond the scope of the corresponding measures based on these information, the corresponding parameter control, has very important significance.
    This design USES the detection module have temperature and humidity, light intensity sensor, co2 sensor, sensor noise, are all digital sensors. Sensor module is integrated with sensor and relevant circuit, can be directly measured data as input signal of single chip microcomputer, then by single chip microcomputer to get signal processing, and then through the display module display the corresponding measured values.Under a machine with the temperature and humidity sensors, light sensors, carbon dioxide concentration sensor and noise sensor connection of single chip, each classroom has a lower machine, so there are a lot of a lower place machine and superordination machine to monitor multiple bits of the machine. Alarm circuit and display circuit are connected to the PC.
