Abstract

Purpose. The article is devoted to the development of a power facility personnel control system using radio frequency identification technology (RFID). The main components of this system are RFID readers and RFID tags attached to personnel's clothing. The process involves video surveillance, monitoring and access control systems at a power facility. The alert and information control system at a power facility under normal operating conditions can improve the quality of production and technological process management through the use of a video surveillance system and access control, and in case of a fire or emergency it plots a safe route to the emergency exit and provides information about the presence of people in the room. Methods. Based on calculations, the dependence of the values of energy and modulating range parameters on the choice of RFID tags and readers for various conditions of use is obtained. Findings. Calculation, using formulas (1) and (2) for the values of the stationary reader parameters in the 900 MHz range (P = 1 W, GR = 4, λ = 30 cm, SR = –100 dBW, kE = 0.5) and tags with antennas in the form of half-wave dipoles (Ae = 0.01 m2, Δσ = 0.06 m2, S = 30 μW) allows obtaining the energy range RE ≈ 7 m, and the modulation range RM ≈ 25 m. In the design process the use of formulas (1) – (5) allows determining the RFID equipment technical parameters, which provide the required coverage range. Research application field. It is advisable to include the results of the study in the research and development work of the research organizations of EMERCOM of Russia and other ministries and departments. Conclusions. The development of the system for personnel warning and access control at a power facility using radio frequency identification will make it possible not only to ensure production and technological process control, having information about the exact people's location, but also to evacuate personnel to a safe area in case of a fire or emergency.
