Abstract

An open numerical control system base on PC machine is provided, which relates to a numerical system base on Windows, and is used for solving the problems in the existing numerical system based on Windows, such as poor real-time performance and high development cost, as well as the problem in a numerical system based on WINCE of poor compatibility between hardware and software. A real-time scheduling module of the invention is used for establishing connections between PC machine and a hardware interface board and scheduling real-time tasks; a CNC module is used for establishing sharing memory area in the memory of PC machine and connecting with the real-time scheduling module, as well as realizing position controlling function through the real-time scheduling module schedules real-time tasks; a PLC module realizes a logical controlling function through the real-time scheduling module schedules real-time tasks; a man-machine interface module transfers input path procedure, set operation mode and data collocation of operating system to real-time task and displays execution result of real-time task to user; the real-time scheduling module, the CNC module and the PLC module are all embedded in the Windows operating system, the man-machine interface module is a universal Windows procedure.

Description

technical field [0001] The invention relates to a numerical control system based on Windows operating system. Background technique [0002] At present, Windows series operating systems occupy a dominant position on PCs. Its standard and beautiful graphical user interface (GUI) and convenient and fast operation methods have not only been accepted by ordinary users, but also more and more users in the field of industrial applications. more. [0003] However, Windows is a multi-tasking operating system. The software and hardware resources of the PC are shared by multiple programs, resulting in poor real-time performance of the system. If the system resources are occupied by other programs, the CNC program cannot meet the real-time requirements, and the CNC program cannot meet the real-time requirements. The requirements for real-time and continuity are very high, so it is difficult to ensure real-time performance under the Windows operating system environment, and it is diffic...
