Detailed Description
The technical scheme of the invention is further explained in detail by combining the drawings in the specification.
The NB-IoT-based intelligent classroom remote monitoring system mainly comprises three parts: classroom monitor terminal, wireless transmission module and monitoring platform. The external information that will gather through classroom monitor terminal sends the monitoring platform to through wireless mode in the classroom to realize all things interconnection fundamentally, promote wisdom municipal development. The system is mainly designed from 3 aspects, the first part is a classroom monitoring terminal, and the classroom information is monitored in real time by using an Arduino development board to control an electronic device to acquire an external signal; the second part is a wireless transmission module which is in charge of communication between the acquisition terminal and the monitoring platform by utilizing NB-IoT narrowband Internet of things technology; the third part is a monitoring platform which can analyze and calculate the information uploaded by the terminal and store the information into a database, so that a manager can check the information in real time conveniently.
The monitoring terminal takes a classroom as a carrier, the external module is controlled by the main control module, the collected information can be stored in the development board and then sent to the server through the NB communication base station and the core network, and the monitoring platform on the server can analyze and calculate the received information, so that the information of each terminal can be monitored in real time.
The intelligent monitoring node design implemented by the classroom monitoring terminal is actually the intellectualization and the Internet of things of the classroom, namely the useful information acquired in the acquisition system is transmitted to the monitoring platform in a wireless network mode, so that an observer can accurately know the classroom situation in real time, and convenience is brought to classroom management. The monitoring system collects campus card information of students in a classroom, classroom positions and equipment states respectively, and then sends collected information to the monitoring platform in a wireless transmission mode.
The functional design of each module in fig. 1 is as follows:
a power supply module: the module is designed to provide voltage suitable for the working range of the acquisition module, the main control module and the communication module.
An acquisition module: and an RC522 radio frequency module and an NEO-M8N positioning module are adopted to collect student campus card data and position information of the equipment.
The main control module: the module is designed to control the acquisition module, encode the acquired data in an agreed format, and transmit the encoded data to the cloud server through the wireless transmission module.
A wireless transmission module: a BC95 communication module is adopted, the BC95 communication module utilizes NB-IoT communication technology to send collected data, and in addition, commands sent by the platform are also sent to the main control through the BC95 communication module.
The design of the monitoring platform is based on a Web system of a B/S structure, the B/S structure Web system is developed by using an IDE tool Eclipse under a Win10 system, a front-end page is compiled by using Vue.js, a server rear end is compiled by using node.js, MySQL is used as a database of the website, the JSP is loaded with a database drive to be connected with the database, a data file is called in the JSP, dynamic information of the acquisition system is monitored in real time, the attendance of students in the current classroom can be rapidly and visually displayed, corresponding measures can be taken by managers according to different classroom conditions, the monitoring platform does not need to watch the personnel for a long time, when abnormal conditions such as attendance and the like are monitored, the platform can send information to the managers through a network, so that equipment and human resources are optimized, and classroom workers can conveniently configure and modify terminals. The monitoring platform issues commands to configure the terminal acquisition system, and can set adaptive message pushing thresholds according to different classroom environment conditions. The model of the system is shown in figure 2. The writing is divided into the front-end module and the back-end module for writing, and the writing has the advantage of facilitating the writing of codes and subsequent maintenance.
The design steps of the monitoring platform are as follows:

Unlike other front end frames, Vue is designed to be applied layer by layer from bottom to top. Vue, the core library only focuses on the viewing layer, not only is it easy to get on hand, but also it is easy to integrate with third party libraries or existing projects.
(2) And (4) selecting a database. The platform database adopts a MySQL database, the MySQL database can be used for corresponding to the current data storage, and the Oracle database can be selected if the data volume is huge. The reasonable database table structure is beneficial to improving the performance of the database.
(3) And designing a user management module. The system mainly aims to establish a time-efficient and reliable classroom monitoring system management platform on a cloud platform. Therefore, after the basic environment of the system is configured and before the device is specifically managed, a user management module is firstly arranged to manage the user entering the classroom detection system management platform. The administrator can configure the user's rights, modify the user's information, and log off the user.
(4) And designing a data analysis module. The function is designed to analyze the data uploaded by the classroom monitoring terminal and display the data in a calculation mode. The uploaded data contains equipment zone bit information, if the zone bit is 0, the equipment works normally, otherwise, the equipment is abnormal. The reasons for the abnormality of the device are many, such as insufficient power, malfunction of the positioning module, and so on. The manager can set an abnormal alarm threshold, if the abnormal quantity exceeds the threshold, the platform alarm function is triggered to inform the manager to process, and in addition, the requirements on classroom resources and the attendance number of students can be set. The results of the data analysis are presented in text or in a graphical form, such as statistical analysis by date, and may also specify the source and date of the data.
In a data analysis module provided with a data real-time monitoring interface, the system monitors data in real time and broadcasts alarm information in a rolling mode, wherein the information comprises abnormal brief information, time, alarm level and position icons. After the classroom is selected, the position of the classroom can be automatically updated on a hundred-degree map in real time, and the abnormal classroom can display a red icon. As can be seen from fig. 3, the current collected information is displayed in the lower data bar at all times, and the user can conveniently view the data information.
