Safe automatic parking method and system for coke oven electric locomotive

Abstract

The invention belongs to the technical field of mechanical control, and particularly relates to a safe automatic parking method and system for a coke oven electric locomotive. The method comprises the following steps: acquiring deformation distance data by a radio induction technology; the running linear speed of the electric locomotive is calculated according to the deformation distance data, the running linear speed of the electric locomotive is calculated according to the deformation distance data, 1-4 speed reduction gears are set, the speed of the first gear is the lowest, and the speed of the fourth gear is the highest; variable-frequency speed regulation is adopted, and the dragging scheme is one-dragging-one; a deceleration point and a stop point are preset, when the electric locomotive runs to the deceleration point, the speed of the electric locomotive is reduced from the fourth gear to the third gear, from the third gear to the second gear and from the second gear to the first gear, and after the electric locomotive reaches the stop point, the electric locomotive stops safely. The problems that compared with a coke oven vehicle, fatigue driving or inattention is more likely to happen, the deceleration buffering distance of the electric locomotive at the lower portion of the dry quenching tower is short or the electric locomotive does not decelerate, and the electric locomotive falls off a track and hits against a safety gear for many times are solved.
