| Abstract: | Automobile industry is developing most extravagantly. The
maintenance of the automobiles plays an important role, which is achieved by
latest service station equipments. Electro-mechanical two-post lift is used to
lift the vehicle to top or bottom and performs the required service operations
under chassis. As in the present design and fabrication of the two-post lift,
sprockets and chain mechanism are present for the transmission of the drive,
but this results in slight non-linearity in the arm arrangements. This
non-linearity in worst case may result in destruction of the automobile placed
on the lift. The main aim of this paper is to avoid this non-linearity hence
synchronization control of the arm movements is proposed for automating the
lift, by removing the sprocket and chain mechanisms. The synchronization is
implemented using two types of controllers, which includes micro-controller and
the programmable logic controller. An inductive proximity sensor is selected to
sense the rotation of the motors and produce pulses, which is used to control
the movement of arm arrangements. The micro-controller programming is
implemented using the software AVR Studio 3.5. The programmable logic
controller programming is performed using the software STEP-7 Micro/Win 32. |
