FIELD: measurement equipment.
SUBSTANCE: invention relates to a speed data transfer device in a vehicle with a metering head 3 for registration of motion, the appropriate metered signal of which is sent both into a unit 5 of applied system control unit and into a unit 4 of protection control. The metered signal is processed with the unit 5 of applied system control, and processed data is on a real time basis sent into a comparing unit of the control device, besides, the metered signal is processed in the unit 4 of protection control, and processed data is coded in the coding unit, and the coded data is recorded into a memory unit. The content of the memory unit via certain intervals of time is transmitted into the control device. The control device comprises a decoding unit for decoding of the received memory content and transfer of the decoded memory content into the comparing unit of the control device, in which the decoded memory content is compared with the data of the unit 5 of applied system control, and in case of a deviation a warning signal is produced. All elements of the metering head 3 and the protection control unit 4 comprising a coding unit and a memory unit are installed in a single unit 1 of the integrated chip.
EFFECT: invention improves device reliability.
