DATA ACQUISITION, PROCESSING AND TRANSMITTING UNIT OF LOCOMOTIVE Russian patent published in 2004 - IPC

FIELD: railway transport; locomotive control facilities.

SUBSTANCE: matching device installed in housing is provided with connectors and digital channels for connecting discrete signals pickups, being connected to central processor. Said processor designed for processing signals from pickups and transmitting them to central computer includes microcontroller with built in controller of customer access network (CAN), transceiver of serial bus of customer access network for executing communication with central computer, on-line storage and transceiver of serial port type RS-232. Matching device is furnished with analog channels to connect analogue signals pickups and analog-to-digital converters. Central processor is provided with flash memory and it includes additionally software for calibrating of analog channels. Serial port transceiver is designed for interaction of analog channels calibration program with corresponding terminals or PC-compatible computer. The latter is provided with terminal emulation program and is designed for putting in data and indication of calibration procedure. On-line storage provides recording of current calibration coefficients, and flash memory preserves result of calibration.

EFFECT: provision of universal data acquisition, processing and transmitting unit which can be used in universal driver's cabin.
