Abstract
Industrial production for control of the online needs of transport projects designed automated production line material shipped the car's automatic control system working process. The control of two-way process control, and transport material from a car three-phase asynchronous motor drag, the motor is transferred, the right car line, the electrical reversal, the car left line. In line with five for the 1-5 coding site for car parking, a berth in each of the installation of a trip switch to monitor whether the car arrived at the site.
The Yun-expected car control system used by the Japanese OMRON company's 30 points CPM2A series of P PLC to the main control device, the preparation of software instructions to achieve their specific control requirements in the design process of the use of the PLC support Relay to achieve control functions in accordance with the interlocking first press priority control requirements, use special relays to achieve data transmission of data from the register data to determine the size of the car to achieve control of the direction of travel.
The control system for flexible manufacturing system in the car's automatic control of materials, automated warehouses in the car's automatic control access to objects such as the control system low price, small size, can secure production, and high efficiency, flexibility Strong, very good to adapt to change and correct mistakes, fast and easy to manage.
Key words: PLC; car control, automatic production line; monitoring programme
