With the increase in the number and size of school campuses, the issue of campus energy waste has received extensive attention. In order to monitor the environment of the classroom, control the electrical appliances to reduce energy consumption, and analyze the environment and utilization of the classroom, this paper develops an intelligent classroom management system based on the Internet of Things. In this system, the sensor suite of Shanghai Qixiang Technology Co., Ltd. is used as the basic suite of the Internet of Things. The storage model is established by the relational database MySQL and the non-relational database HBase. And the B/S-based website is the user interface. The storage overhead is reduced to a certain extent, and the energy waste in the classroom is effectively reduced.

Introduction

Due to the lack of attention of the leadership and the lack of effective management, the school’s power was wasted. It is not uncommon to leave the classroom without turning off lights, fans, and air conditioners. At the same time, the computers and switches in the equipment room consume a lot of power when they are not in use. However, in the process of automatic control, it is necessary to evaluate a large number of parameters, such as automatically turning off the lights in the room, and need to judge the current external light intensity, whether the classroom is active or not. At the same time, the indoor environment has a direct impact on people’s health, quality of life and work efficiency [1]. With the development of the Internet of Things, people can get the surrounding environment at a lower cost. In order to achieve energy saving and emission reduction in schools, it is necessary to intelligently control the school’s lamps, air conditioners, projections and other electrical equipment. However, in order not to affect the learning and working environment of teachers and students, it is necessary to find a balance that can save energy, reducing the operating costs of schools and meet the daily needs of teachers and students. Therefore, environmental data of classrooms and offices are needed to record the activities of students and teachers, the environmental changes in the room and the use of electrical appliances, and to analyze the data in the later stage to find a balance point. However, the amount of data generated spontaneously by the Internet of Things is very large. Each classroom generates a large amount of environmental data every day. The traditional relational database can no longer meet this demand. There is an urgent need for a new way to store data. Big data technology The emergence of this can solve this problem very well.
