FIELD: physics, signalling. ^ SUBSTANCE: invention relates to methods of protecting objects from access by unauthorised persons and registering object servicing personnel. The method of identifying a subject on a serviced object involves touching or bringing an access authorisation device mounted on the object close to an intellectual key which reads information from the said device. The access authorisation device on the object is an identifier with a unique code, which includes a built-in microcircuit and operates in "request-response" mode. The intellectual key is based on a GSM-modem with a SIM-card and a unique number, and has a reader connected to a microcontroller which can read the unique SIM-card number and the unique code of the identifier. The method also involves transmitting said codes in form of control code information to a dispatch centre which decides on authenticity or inauthenticity of the received information. In case of the former, a subject receives a light signal on the light-emitting diode of the intellectual key and the identification process is repeated in case of the latter. ^ EFFECT: invention enables monitoring operation of a subject in real time. ^ 1 dwg |
