Parking Availability and Gate Control System by Using PLC and HMI

Abstract

The programmable logic controller(PLC)and human machine interface (HMI) have been successfully applied to a wide variety of practical problems such as the Parking Availability and Gate Control system. It has been shown that this programmable logic controller performs better than conventional system, especially when applied on processes that have a difficult model andwhen there is heuristic knowledge from human operators. The SIMATIC S7-300 PLC has been used because it is one of the most common used in automated system. The main objective of this research is to design and implement the Parking Availability and Gate Control system.The Gate Control system using led indicators to compensatea DC motor which has been controlled by PLC and HMI to help and guide the driver. The model has been programmed by using SIMATIC STEP7300and HMI WinCC flexible software. The model has been implemented and built.
