A NOVEL APPROACH OF LIFT CONTROL IN AUTOMATIC CAR PARKING USING PLC

Abstract

In the today situation, where parking of four wheeler vehicle is very severe problem in urban region. It is crucial time to avoid the wastage of space in urban areas, as the no of vehicles are increasing day by day. An automatic parking (multilevel) strategy should be developed where parking problems arise intensively, which involves space reduction. In this paper a novel approach for lift control is proposed in fully automatic Level Car Parking System which used to take cars in/out of system & park the cars. Entire system is controlled using a Programmable Logic Controller (PLC). As speed control is required for multiple speed setting & proper stopping accuracy, the lift will be driven by the VFD (Variable Frequency Drive) for speed control. The pallet position on lift, accurate positioning between lift-level & safety interlocks are sensed from dedicated sensor. EPLAN software for used for electrical panel design purpose whileTWINCAT PLC control is used for auto/manual modes programming & simulated results.
