PLC BASED CONTROL OF AUTOMATIC CAR PARKING SYSTEMS
“One man can do the work of a hundred ordinary men, but no machine can do the work of an extra-ordinary man.”
In this fast developing science revolutionary era, automation of industry has become a necessity. A PLC(Programmable Logic Controller) is a programmable system used for automation. The Programmable Logic Controller may be defined as
“A PLC is a microprocessor based specialized computer that carries out control functions of many types and levels of complexity.”
We have designed a kit for automating a car parking system. For this a PLC has been used. The PLC has been pre-programmed and is the brain of the system. It reads the inputs from the various sensors and makes logical decisions. Accordingly the necessary operation is carried out. In case of occurrence of a failure, the protective measure is also taken. Our project illustrates only a simple application of the PLC, while the PLC is a powerful tool the applications of which are innumerable and complex.
