Embodiment Construction

[0034] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the described embodiment.

[0035] Such as figure 1 The overall framework of the reconfigurable method is shown, and the reconfiguration of the autonomous domain control module is oriented to the partial reconfiguration of the mechanical system of the reconfigurable machine tool. It is suitable for the situation that when the processing task changes, the mechanical system of the machine tool itself does not need to participate in the execution of the processing task, but only part of the mechanism can participate in the work to meet the task requirements. The topology of the mechanical system o...

Abstract

The invention relates to a reconfiguration method of a control module of a reconfigurable digital controller in the technical field of computer digital control, including the following steps: step 1, establishing a topological structure of equipment; step 2, setting up a topological structure of an autonomous domain; step 3, adopting a configuration system software to fulfill reconfiguration; the reconfiguration includes the following steps: (1) a user inputs task information and the topological structure of the autonomous domain into a GUI module and sends the task information and the topological structure to a task controller module; (2) the task controller module includes a task interpretation module and a state decision module, the task interpretation module can interpret information into a data type, which can be identified by a motion controller and an I / O controller according to stated syntax rules; the state decision module controls the concrete behavior and the process of the motion controller module according to the principle of a finite state machine; (3) the task controller module sends motion instruction to the motion controller module and the I / O controller module so as to control the motion of a motor, thus fulfilling the task of reconfiguration. The method of the invention can ensure that the controller can realize the fast reconfiguration of the control module according to different processing tasks.

Description

technical field [0001] The invention relates to a method in the technical field of computer numerical control, in particular to a method for reconfiguring a control module of a reconfigurable digital controller. Background technique [0002] A reconfigurable manufacturing system is a manufacturing system that has the two functions of actively adapting to changes in the external environment and passively responding to internal disturbances in the system. The function and production capacity of the system can adapt to changes in product varieties or changes in market demand. The six characteristics of a reconfigurable manufacturing system are modularity, scalability, integrability, transformability, customization, and diagnosability. Among them, modularity is the core feature of reconfigurable manufacturing system. A reconfigurable manufacturing system consists of an upper layer reconfigurable digital controller and a lower layer reconfigurable machine. Reconfigurable digit...
