At present, in the development process of the workpiece table motion control system, the industrial computer is directly connected to the actual table body, and the human-computer interface sends instructions or parameters directly to the industrial computer. The motor drives the table body to move, but during the debugging process, unexpected factors such as incorrect command input at the human-computer interaction terminal or incorrect control algorithm setting may cause serious consequences such as collision with the table, resulting in immeasurable losses

The invention discloses a method for double-workpiece-platform semi-physical simulation based on the virtual reality technology, and relates to the method for the double-workpiece-platform semi-physical simulation. The method is used for meeting the demands for the double-workpiece-platform semi-physical simulation. The method comprises the steps that a user inputs a position order to an upper computer operating system; the upper computer operating system sends the position order to a VME industrial personal computer through Ethernet to be decoded; parameter adjustment is controlled by a control model which controls a motor model to work and controls an operating platform mathematical model to move; the working process of the motor model and the moving process of the operating platform mathematical model are synchronously sent to the upper computer operating system through the Ethernet; the upper computer operating system sends the working process of the motor model and the moving process of the operating platform mathematical model to a three-dimensional simulation model through a dynamic link bank, and the three-dimensional simulation model synchronically demonstrates the working process of the motor model and the moving process of the operating platform mathematical model in real time. The method for the double-workpiece-platform semi-physical simulation based on the virtual reality technology is suitable for the double-workpiece-platform semi-physical simulation.
Description
technical field [0001] The invention relates to a semi-physical simulation method of a double workpiece platform. Background technique [0002] In the manufacturing process of lithography machine, the development of double workpiece table plays a decisive role. At present, in the development process of the workpiece table motion control system, the industrial computer is directly connected to the actual table body, and the human-computer interface sends instructions or parameters directly to the industrial computer. The motor drives the table body to move, but during the debugging process, unexpected factors such as incorrect command input at the human-computer interaction terminal or incorrect control algorithm setting may cause serious consequences such as collision with the table, resulting in immeasurable losses. [0003] Virtual reality is a new control method for people to visualize and interact with complex data through computers. Compared with traditional man-machin...
