PURPOSE:To stop a moving equipment such as an automatic storehouse and an automtic crane which move to an objective address automatically and then stop at a fixed position highly accurately by detecting the speed of the moving equipment at the fixed position and correcting the difference between the detected speed and a designed speed. CONSTITUTION:The moving equipment 1 has an arithmetic device 6 calculating the difference between the designed speed and the real moving speed and correcting the real moving speed and rotates a wheel 4 by the rotation of a motor to move on a rail 5. The moving equipment 1 is provided with a detector 2 and strikers 3 for addresses are arranged on the earth side opposed to the detector 2 by the number of stopping addresses. Since the distance LA-B-LC-D between respective addresses are already known, the speed between B and C can be precisely grasped. Consequently, the arithmetic device 6 calculates the difference between the designed speed and the real moving speed and corrects the decelerating speed from a high speed to an intermediate speed and from the intermediate speed to a low speed, so that the moving equipment can be stopped a point D accurately. |
