FIELD: safety control of motion of long-stock heavyweight trains. ^ SUBSTANCE: speed is measured at which speed longitudinal dynamic force emerging at urgent (intensive) braking doesn't lead to excess of allowed values at any point of line while taking profile of line, its plan, distribution of masses of cars along the train and break characteristics of train. The speed measured is supposed to maximal admitted. Preset curve of speed limitation of train's motion is corrected on the base of the speed which limit determines longitudinal dynamic force in train in case of urgent braking. When regulating speed of the train, the value of current speed is compared with value preset by corrected curve of speed limitation. In case the value is exceeded, the speed is lowered forcedly. ^ EFFECT: improved safety of motion. ^ 4 cl |
