ACCESS CONTROL SYSTEM BASED ON RFID TECHNOLOGIES

Abstract

Implementing security and preventing information leakage in an enterprise is one of the most important and significant problems in many enterprises nowadays. Traditional methods of personal identification, based on the use of passwords or physical media, such as a pass, passport, driver's license, do not always meet modern security requirements and require constant human involvement. One of the most developed and effective means of solving these problems is the use of automatic security alarm systems of various types. The automatic security alarm system is used when equipping various types of premises. At the same time, its purpose is to record any possibility of illegal entry into the protected premises or the protected territory. The basis of the security system is control sensors that transmit information to the central control point. At the same time, the security alarm can be not only autonomous, but also function in a complex with other security systems of the protected object. Automatic security alarm systems allow you to monitor the premises or territory 24 hours a day.

In this work, a system for managing access to the premises at the regime enterprise was developed, which in turn was implemented in the form of a mock-up. The authors conducted a study of the existing access control and management systems and identified the functions that are currently implemented in the ACS. Based on this, a goal was set, as well as requirements for system development were formed, and a conclusion was drawn about the need to develop a system with the lowest economic cost. A structural diagram of the ECU controller and a diagram of the functional structure of the system were developed. The composition of the elements included in the structure of the system is also defined. Modeling was done using selected components and developed structural and functional schemes. Modeling made it possible to verify the correctness of the construction of the system structure and provided the possibility of developing an electrical schematic diagram.
