The Realization of Automatic Positioning of Crane in High Precise in the Storehouse for Nuclear Waste
This paper sets forth the on the realization of automatic positioning of crane in high precise in the storehouse for nuclear waste. In order to realize the positioning control for three-dimension motion of crane, the three control loops are constructed with the programmable logic controller at core. The positions of the crane and the trolley are measured by the laser distance measurement modules, while the motions of the crane and the trolley are automatically positioned by means of the on-off control of intermediate relays and AC contactors and frequency control of inverter driving motors. The position of the hanger is measured by the rotary encoder, while the hanger lifting is automatically positioned by means of the on-off control of intermediate relays and AC contactors. The overtravellimit switches are allocated at three motion directions each other to construct three protecting loops and restrain the motion of the crane within the safety ranges. The test data shows that the automatic positioning precision of crane motion in the level is less than 2 mm.
