The PLC-based Control System for Intelligent Garage

摘要

For now, the urban land has become more scarce and expensive. So, for the parking lot, the traditional manual management mode that has low land utilization must be changed in order to decrease building area and enhance land utilization. For this purpose, this paper proposes a design based on PLC to control intelligent garage. This plan uses the S7-300 serial products of Siemens as main control device, and use the HMI touch panel to collect the location information when picking or parking. After being calculated by S7-300, a control signal will be transmitted to relay for moving the parking platform to assigned location, achieving that automation of car in and out garage management. The feasibility and validity of this system has been verified by software simulation in the STEP 7.
