摘要教室是学习的场所，老师和学生受教室环境的影响比较大。而很多事件会对教室的环境造成影响，如一些教室的施工会造成噪音的污染、夏季或者冬季温度会过高或过低、人多的时候容易造成二氧化碳的浓度升高，这些都给日常的教学活动带来了负面影响。长此以往，教室的环境并未受到足够的重视，而由教室环境比较差带来的影响长期影响着中小学甚至高校的上课效率。如果用基于单片机的集散式网络监控系统对这些参数进行监控，并在超出范围的时候进行报警，基于这些信息采取相应的措施，对相应的参数进行控制，可以有效的改善教室的环境，提高课堂质量，具有非常重要的意义。35838
本设计是一个用于监测教室环境的集散式网络监控系统，各传感器检测到的教室的温度、湿度、光强、二氧化碳浓度、噪声强度的数据发送给单片机，单片机根据所采集的信息进行分析判断，当超出设定数值后，发出声光报警。本设计所使用的传感器有温湿度传感器，光强传感器，二氧化碳传感器，噪声传感器，均为数字传感器。传感器模块已经集成了传感器和相关电路，可以直接把测量的数据作为单片机的输入信号，再通过单片机对所得到的信号进行处理，然后通过显示模块显示相应的测量值。下位机由与温湿度传感器，光强传感器，二氧化碳浓度传感器和噪声传感器连接的单片机构成，每个教室对应一个下位机，所以存在很多个下位机，上位机对多个下位机进行监控。

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.
