METHOD OF AND SYSTEM FOR REMOTE CHECKING OF RAIL CAR LOADS FOR FALLING WITHIN CLEARANCE LIMITS Russian patent published in 2007 - IPC B61K9/02 G08B13/196 

FIELD: railway transport.

SUBSTANCE: invention relates to remote control of sizes of loads carried by rail. Method includes checking of observation of obstruction clearance limits, when train enters check zone, by means of optoelectronic sensors and determining whether loads lie within gauge limits when train passes check zone formed by optical limits of clearance gate sensors, comparing loading gauges with required train gauges and video observation of passing train. Set of two pairs of optoelectronic sensors "radiator-receiver" are installed in each plane under checking, time of overlapping of optical channel is measured as well as speed of train, and length violation of gauge is calculated. At least two radiation receivers are installed in plane under checking at a distance, and radiators mated with receivers are installed close to each other as possible to form optical axes arranged at angle relative to each other. Out-of-gauge coordinates are determined and obtained information is transmitted by communication channels, being visualized on screen of videomonitor, and attention of operator is drawn to violation, alarm signal is sent and response of operator is recorded. Device contains speed meter, radiators, receivers, computing device, videomonitor and operator response detector.

EFFECT: improved reliability.
