SNOWPLOW WORKING ELEMENTS AUTOMATIC CONTROL SYSTEM Russian patent published in 2016 - IPC B61D15/00 E01H5/00 

FIELD: transport.

SUBSTANCE: invention relates to control over railway cleaning equipment. System comprises two transceivers, which antennas are installed on snowplow roof in its head and tail parts and continuously emitting radio signal, irradiating base in horizontal plane with width equal to snowplow width with open wings at specified distance to snowplow. Two Doppler narrowing beams units DOL are performing radio-locating range-finding Doppler processing of reflected signals received by transceivers, computer based information processing and control unit calculates working members position and process obstacles coordinates and generates required combinations of signals levels at corresponding step bipolar electric motor windings. At that, system also includes front shield and side wings spool-type pneumatic valves, front shield and side wings pneumatic cylinders, controlling operation of corresponding working element, and working members position sensors.

EFFECT: preventing snowplow working members with process obstacle contact interaction.
