Background The speed and parking position of a rail consist wagon is affected by a number of factors, such as peak speed, line grade, weight, distance travelled, etc. The marshalling station hump control system calculates the 'preset' running speed and the 'preset' parking position in the linking area through software, and the speed regulating equipment arranged in the linking area often has larger deviation between the actual running speed and the 'preset' parking position due to the reduction of speed regulating capability caused by aging, oil gas leakage and faults. The parking position may be too close to the warning sign to cause "door blocking" when the consist vehicle is running too low, or not have sufficient speed, for example less than 5 km/which may cause "sunroof" when linked to the lead vehicle, and may cause "overspeed linked" problems when running too high. At present, real-time detection of the running speed and the parking position of a vehicle in a continuous hanging area of a railway freight marshalling station is still blank, and phenomena of door blocking, skylight and overspeed continuous hanging appear in a long time, so that a great deal of extra work is brought to shunting operation of the marshalling station to reduce efficiency, and risks such as vehicle damage, rollover, derailment and the like even occur in serious cases.
