FIELD: transport engineering. SUBSTANCE: data exchange between wireless communication units carried by User and mounted on vehicle is provided. Said units are built respectively into User's cellular telephone set and vehicle mounted antenna unit. User is remotely identified by marks and radio trinkets. Prior to polling, antennal unit mounted on vehicle is connected by cable-programmer to active inductive antenna and is set for radiation, and cable-programmer is energized. After brining the mark in zone covered by said antenna and receiving replay signals, polling signals of wireless communication. User-carried unit are radiated by antenna of vehicle-mounted unit, and inquiries for radio exchange of data and introduction of secret code are displayed. Using keyboard, replies for inquiries are entered and, if conditions for radio exchange are provided, cable-programmer is disconnected from active inductive antenna, vehicle-mounted antenna unit is set in operative mode, and signals from antenna of vehicle-mounted wireless communication unit are transmitted to protection system. EFFECT: improved efficiency of protection at enlarged service capabilities and improved convenience of operation and servicing. 3 cl, 1 dwg
