AGV forklift intelligent logistics system in smart factory

The smart factory is the goal of the transformation of the traditional manufacturing enterprise factory, and the production technology that the enterprise must possess in the future. The mobile handling robot AGV forklift transports the goods from the simple position to the designated position, and the technology develops to big data, internet of things, cloud computing, etc. Throughout the product design, the mobile handling robot AGV forklift becomes a new intelligent industrial equipment with real-time sensing, safety identification, multiple obstacle avoidance, intelligent decision-making, automatic execution and other functions. At present, AGV forklifts have been used in various fields and become an important tool for logistics handling.

The AGV system is mainly composed of AGV forklift, ground navigation and positioning system, charging system, industrial intelligent gateway wireless communication, vehicle PLC and AGV cloud platform. Among them, the industrial intelligent gateway has its own WIFI function, installed inside the AGV body, through the workshop. Wireless APs in different areas (or through 3G/4G networks) establish wireless connections, complete security features to protect the system from attack, support wide operating temperatures, meet a variety of harsh outdoor environment applications, ensure scheduling system center and on-site motion The communication of the AGV vehicle is correct.

The AGV forklift is controlled by PLC. The trolley (industrial robot) carries an industrial intelligent gateway, which can communicate wirelessly with the AGV intelligent logistics monitoring system cloud platform and execute the instructions of the AGV dispatching system. The AGV dispatching system monitors the operating status of all AGV forklifts in the system according to the position and status signals reported by the AGV forklift. When an abnormality occurs, the alarm operation is completed, and the transport demand of each station in the transport system is also collected, and according to each transport station. The signal status automatically assigns the task of the AGV forklift. Based on the read data, the PLC causes the AGV forklift to read the ground mark through RFID and make corresponding actions (changing speed, steering, positioning and parking, etc.) to realize the function of the AGV forklift dispatching system. , site location function.
