Method for realizing vehicle type transmission of vehicle welding production line

The invention discloses a method for realizing vehicle type transmission of a vehicle welding production line, which belongs to the technical field of vehicle welding production and comprises the following steps of: performing data interaction with a central control system and receiving vehicle type order information issued by an upper computer; writing vehicle type order information issued by the central control system into a global data block of an intermediate data storage area; issuing the vehicle type order information of the intermediate data storage area queue to each material port; and after the workpieces are manually fed through the material ports, vehicle type orders are transmitted along with the workpieces. According to the invention, all the material ports in the workshop line body receive the vehicle type orders and instruct manual feeding, the vehicle type order information issued by the central control system is transmitted to each material port and station in the line body, and the whole veh
