Abstract
This article introduced based on programmable controller (PLC) and the Profibus main line's garage control system, summarized three three row type seven berth to rise and fall moves to the type three-dimensional to stop the garage horizontally the principle of work, the unique feature, and through the PLC software design and the optimization, has realized the three-dimensional garage automatic control. The overall system by the steel structure part, carries the template part, the transmission system, the control system, the safety protection measure and so on to be composed. Controls overall system's movement with the PLC in pre-placed procedure, transfers with electrical machinery's pro and con controls berth's about to move, electrical machinery's rotational speed and is reversing controls by the frequency changer, parking splits out the certificate by the bar code printer, takes Che Ze to sweep into this certificate with the bar code scanner PC machine, in passes to PLC through the Profibus main line, realizes deposits and withdraws vehicle's automation. This system divides into three work processes: The automatic movement, the manual movement and the stop movement, the available change-over switch controls. Also has the following protection function: Stops, the power failure maintains anxiously, the ultra long prompt and leaves the vehicle protection.
