MODELING OF AUTOMATED CONTROL OF FIBER-OPTIC COMMUNICATION SERVER ROOM

The article is devoted to modeling the development of an automated monitoring system for server rooms of railways and subways in accordance with modern requirements. The premises must ensure safe, reliable and uninterrupted operation of all equipment and servers included in the information technology system, and also comply with international standards. Since equipment is more expensive and sensitive to temperature and humidity, server rooms must have reliable power supplies, devices and climate control systems. To ensure the security of the system, video surveillance devices, control of entrance doors, and to protect fire alarm devices, automated fire extinguishing systems, etc. should be used. To ensure efficient operation of these systems, microprocessor control must be used. An automated control system for server rooms, built on the basis of a programmable logic controller of the Siemens S7-1200 type, was modeled using the Tia Portal application software. Taking into account the characteristics of the equipment of the fiber-optic communication server room, the Tia Portal program simulates the operation of control systems for temperature, humidity, entrance doors and fire safety of the room. Thanks to the implementation of an automated control system based on PLC, the existing numerous server rooms of railways and subways can be controlled from one point.
