Abstract

The invention relates to an open software digit control system, in particular to an open control system of digit control device, for resolving the problems of prior control system as strong control software specificity and dependence on specific hardware system and software design, caused by the non-transplantation and non-extension of software hardware systems. The inventive man-machine interface module can set parameter, edit program and display diagnosis and feedback information, a mission coordinate module can distribute mission to an axial length group module, the axial length group module can complete acceleration, deceleration and mission interpolation, and feedback operation state to the mission coordinate module. The axial length group module reads the information of external device, completes control function, sends the control information to the external device to be executed and feedbacks result to the axial length group module, a control rule module completes the calculation of servo control rule and sends result to the axial length group module, and a software PLC module is interacted with the mission coordinate module to control external device an display result on the man-machine interface module, and user can edit the PLC program via a software PLC development system.

Description

technical field [0001] The invention relates to an open control system of a numerical control machine tool, in particular to a modular reconfigurable open numerical control system whose controller works under the Windows operating system. Background technique [0002] Most of the traditional CNC systems adopt a dedicated closed architecture. The system hardware of this structure is dedicated. The main boards and servo circuit boards of various manufacturers are specially designed, and the products between manufacturers are not interchangeable. The system software structure is special, without portability and scalability, and the control software is highly specific, and its use depends on the hardware architecture and software design ideas of the special control system. With the rapid changes in technology, market, production organization structure, etc., new processing requirements continue to emerge, requiring the CNC system to have rapid, efficient, and economical customer...
