Access points 20 ₁ , 20 ₂ , 20 ₃ are also connected by inputs / outputs with the corresponding outputs / inputs of the floor cabinet 10 (routing unit).

The work of the proposed system is as follows.

Before the start of classes (entering the classroom), the user (teacher) with personal identifier 9 (electronic key, magnetic card), equipped with an individual identification code (IIC), opens the electronic lock 8 of the audience. The signal from the electronic lock 8 via a secure line is sent to the server of the access control unit 7 (BKD) and then to the server of the data center 4 (DPC). The BKD server 7 identifies the identifier 9, fixes the time and, when the IIC coincides with the access authorization time, transmits a signal to the security complex 5 of the audience and issues a confirmation signal to the data center server 4. From the data center server 4, in accordance with the access authorization time, the signal through the floor cabinet 10 (block routing) arrives at the teacher’s terminal 12 in the rack 11 of multimedia equipment (MMO), after which he has access to the materials of the training lesson from electronic storage 3 (electronic database) in accordance with a script written in advance by the teacher for reading the lecture. In addition, with data center 4, through the floor cabinet 10 (routing unit), a signal is sent to the teacher’s terminal 12 to allow connection to access points 20 ₁ , 20 ₂ , 20 ₃ (WiFi) in the audience of user terminals 22 ₁ -22 _n ( mobile workstations of students) or personal computers (PCs), the identification of which is carried out by their login and password for access to the network. When they are registered on the network, a signal with login and password data is supplied through the floor cabinet 10 (routing unit) and data center 4 to the BKD server 7. At the same time, a connection is made for data exchange between multimedia switch 17, multimedia access point 18 and terminal 12 teacher in the rack 11 IMO. In the data center 4, through the floor cabinet 10 (routing unit), a feedback signal is transmitted about connecting the terminals 22 ₁ -22 _{n of} users and / or stationary PCs. The signal arrives at BKD 7, where the number of students attending the lesson is recorded. When fixed in the database of DPC 4, presence data is output to the teacher’s terminal 12 by a signal transmitted through the floor cabinet 10 (routing unit) to the rack 11 of the IMO. During the lesson, Data Center 4 controls access modes from terminals 22 ₁ -22 _n or stationary PCs (full access mode - through a router 2 to the Internet, to electronic storage 3, the material of this lecture or the entire course of lectures; or the test mode when access to external materials missing). The modes are controlled from the teacher’s terminal 12 by transmitting a signal through the floor cabinet 10 (routing unit) to data center 4 and then, if necessary, to electronic storage 3, wired Internet through router 2, other external resources and vice versa.

In addition, during the lecture, the teacher through the multimedia switch 17 can use the multimedia capabilities of the audience: a slide show through the projector 16 on the large screen, the use of the audio system 14 and the camera 13 for reproducing documents, adjusting the audience brightness by the light control unit 19. Most of the lecture material is delivered through the terminal 12 of the teacher of the rack 11 of the multimedia equipment to the corresponding units and / or through the multimedia switch 17. During the operation of the system, additional control is carried out from terminal 1 of the system administrators. When a system error occurs, the signal from the data center server 4 goes to the terminal 1 of the system administrators, from which the system is corrected. After eliminating a system error, a signal is transmitted to data center 4 and the system resumes operation. At the end of the lesson, the teacher can close the access session for students from his terminal 12 with saving the results (tests, laboratory work, etc.) by transmitting the signal from terminal 12 through the rack 11 of the IMO and floor cabinet 10 (routing unit) to data center 4. This session can be closed automatically when the teacher leaves the classroom and the audience door is closed with a personal identifier 9. With this option, the signal from the electronic lock 8 is transmitted via a secure line to the access control unit 7, transmitted to the data center 4, where it processes and the signal for the end of the access session is fed through the floor cabinet 10 (routing unit) to the rack 11 of the MMO and access points 20 ₁ -20 ₃ WiFi. After the audience is closed with user ID 9 and the signal is received on the BKD 7 and data center 4 server, the signal is transmitted to the security complex 5 of the audience. Data Center 4 saves student work. Attendance data, statistics on tests and laboratory work are stored, processed and, upon request, in accordance with the priority of access, can be transferred to the dean's office, educational department and teacher.
