METHOD FOR STOPPING COKE OVEN MOVING MACHINE AT PRESCRIBED POSITION

PURPOSE:To accurately stop a coke oven moving machine at a prescribed position. CONSTITUTION:This method for stopping a coke oven moving machine 7 at a prescribed position is to send a distance signal measured by a preceding distance measuring instrument 1 to a computing element 2 for a stopping position, compute the formula (x) = (1x-1min) (1max-1min) showing the relationship between the distance (x) from one end of a target 3 to a point of measurement and the distance (1x) between a range finder and the target from the shortest distance (1min) and the longest distance (1max) to the target 3 and the preknown projected length (L) of the target 3 in the running direction of the moving machine by the computing element 2 for the stopping position, send the computed formula to the computing element 4 for the residual distance by the computing element 2 for the stopping position, determine the actual distance (x) from the distance (1x) to the target 3 actually measured by the succeeding distance measuring instrument 5 utilizing the formula, compute the deviation from the target value (x0) and send the deviation to a speed controller 6 by the computing element 4 for the residual distance and carry out the stop control of the moving machine 7 according to a well-known speed control by the speed controller 6.
