Research and Design of AGV System Application Based on PLC and RFID

A Flexible Manufacturing System (FMS) is a system which accommodates routine changes, whether predicted or unpredicted. The system consists of ability to apply multiple machines to perform the same operation on a part, as well as system ability to absorb large scale changes, such as capacity and volume. In order to improve the structure of the Flexible Manufacturing System, Programmable Logical Controller (PLC) is used at control processing center, a card reader with recognition RFID is used for Detection device, an Automatic Guided vehicle (AGV) is used for Transportation purpose, and computer network system is applied in Information management and control device. The application of an AGV in Automation Industries has broadened during the late 20th century, this is due to competitive in the worldwide economy, manufacturing operations has to react quickly for meeting clients demand while increasing competitiveness with regard to their own production costs. AGV is a mobile robot that uses independently operated, self-propelled vehicle that follows makers or wires in the flow or uses magnets or lasers for navigation. AGV are known for their flexibility advantages, for these reasons, they are applied in automated warehouses, airports, automated storages to optimize the transportation tasks, and as the result it helps in cost reduction. AGV body is the ultimate transport equipment, its electrical and mechanical properties are directly related to the performance of AGV delivery system. Besides, AGV body with excellent performance will reduce the workload of daily maintenance, and increases the service life of AGV system. In order to improve the AGVs system efficiency and reliability both Siemens PLC and RFID technologies are applied for the design. This paper explains the application of PLC and RFID technologies in the AGV system design for industrial logistic systems. PLC has been widely applied in the field of Industrial Control Equipment, it is used as the controller due to its simple in operation, high reliability, easy programming, and high speed in operation. RFID technology will greatly enhance the efficiency of the Industrial Logistic System in contactless data transmission that guarantees a high suitability for industrial conditions and large scale implementation. SISO (input and output signal) for graphical controller design in Matlab. The aim of applying PLC and RFID for the system design is basically for control and enhancing the speed of data flow. RFID offers many characteristics which make it viable for efficient integration in variety of Industrial and commercial concerns. These data are queried from Automated Guided Vehicle AGV control system at the start of navigation. The PLC detects the position of AGV and the load stand, and controls the movements.
