Industrial Automatic Control Systems and Controllers Annotation << Back Algorithms of Hardware-Software Complex for the Prevention of Bicycle Thefts on the Basis of AuthenticationRFID Card E.O. Vasyukova, A.V. Yakovlev A hardware-software complex designed to reduce the number of bicycle thefts, as well as enable the recovery of a stolen bike with a DB through the use of RFID tags. The article describes the information exchange between subsystems a hardwaresoftware complex and the exchange of control signals for various applications of RFID technology. The protocols of the functioning of the hardware-software complex for the prevention of theft of bicycles based on the authentication of RFID cards will allow you to proceed to the formalization of the models on the basis of which will be developed this complex. Information exchange between the RFID reader card the hardware-software complex reader and the RFID tags of the bike when the authentication operation is formally represented by the chart of sequence, which greatly simplifi es the transition between design phases of hardware-software complex. Keywords: software and hardware complex; RFID device; identifi er; a cryptographic salt; sequence diagram; use case; rental; hash function; layout; the sketch; the Arduino UNO; the protocol.
