Application of sensor technology in smart campus


Every year when the school starts, the issue of campus air quality has become a hot spot of concern for parents. Recently, the Office of the Education Steering Committee of the State Council issued the "Notice on Carrying out the Inspection and Testing of Indoor Air Quality (Formaldehyde) in Newly-built School Buildings of Primary and Secondary Schools" (Guojiao Supervision Letter [2018] No. 72), which notified the newly-built school buildings of primary and secondary schools in various places recently. Indoor formaldehyde exceeding the standard, students dizziness, nosebleeds, etc., require all localities to conduct a comprehensive investigation of the newly completed school buildings and newly purchased facilities and equipment in 2018, and timely discover and deal with hidden dangers affecting the indoor air quality of school buildings. Strong response.

The indoor air quality problem on campus caused by lax decoration or management has a long history. Since 2014, Beijing, Heilongjiang, Hebei, Liaoning,

In Shaanxi, Jiangsu, Anhui, Shanghai, Hubei, Sichuan, Zhejiang, Guangdong and other places, there have been frequent incidents of school runway poisoning. Many students have various degrees of allergic rhinitis, dizziness, cough, nausea, vision loss and other physical discomfort, which greatly affects the health and learning of students. By the beginning of the school season every year, home-school conflicts caused by air quality problems in schools around the world frequently occur. Among these conflict incidents, the kindergarten-related parties are particularly involved.

How to solve the problem of indoor air quality assurance in schools is a hot issue of social concern, and the concept of smart schools has emerged as the times require, using modern sensing technology - campus environment monitoring system to control school air quality. It is understood that dozens of kindergartens in Guangzhou are trying to introduce an air quality monitoring system to solve this problem, and have achieved good results.




What is a campus environmental monitoring system?


The campus environmental monitoring system, also known as the campus automatic weather station, is installed on the campus and can monitor temperature, humidity, air quality, atmospheric pressure and other environmental factors. On the one hand, campus administrators can understand the school environment, warn of pollution, and test the effect of pollution control. On the other hand, it can be used for practical courses in the natural sciences in schools. It enables students to feel the mystery of meteorological knowledge, stimulates students' interest in meteorological knowledge, and guides students to improve their awareness and ability to prevent and reduce meteorological disasters.


In the context of double reduction, the campus is an important place for student learning activities. The clean air on campus directly affects the physical development, health and teaching effect of students.


According to the Standard for Air Quality in Classrooms of Primary and Secondary Schools, it is recommended to install an indoor air quality detection system for air quality monitoring in indoor environments such as primary and secondary schools. The fixed online air quality monitoring system is installed in the indoor environment of the campus. It can be used in conjunction with the classroom fresh air system, and the early warning system can be linked and controlled. It can centrally manage each indoor teaching environment. The ambient air quality provides real-time data query, monitoring and early warning.


The environmental monitoring platform and fixed front-end air monitoring equipment can realize real-time online monitoring and automatic monitoring of the classroom environment, automatically collect and store monitoring data, and remotely transmit and display data through PC terminals for data statistics and analysis, enabling parents and school management departments It can effectively monitor and manage the teaching environment, provide real data for the campus, improve air quality, and purify the teaching environment.

Smart Campus - What are the characteristics of the campus environment monitoring system?




Comprehensive awareness of the environment


First, sensors can sense, capture and transmit information about people, equipment, and resources anytime, anywhere;


The second is to perceive, capture and transmit the individual characteristics of learners (learning preferences, cognitive characteristics, attention states, learning styles, etc.) and learning situations (learning time, learning space, learning partners, learning activities, etc.).




Seamless network interoperability


Based on network and communication technology, especially mobile Internet technology, smart campus supports the connection of all software systems and hardware devices, and information can be transmitted quickly and in real time after sensing. This is the basis for all users to collaborate in a new way to learn and work together.




Massive data support


Based on data mining and modeling technologies, smart campuses can build models based on "massive" campus data, establish forecasting methods, and conduct trend analysis, forecasting and forecasting of new information; Information, rules and other content, through intelligent reasoning, make quick responses and take the initiative to respond, and more reflect the characteristics of intelligence and intelligence.
