Embodiment Construction

[0033] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0034] In order to realize that the numerical control system constructed based on the whole software can take both real-time and reconfigurability into consideration, the present invention provides such figure 1 The whole software numerical control system based on Windows operating system and modular design structure is shown. The system is applied in PC and runs under the environment of Windows operating system.

[0035] see figure 1 , the entire numerical control system can be divided into three parts: the application program layer, the middle layer and the underlying hardware layer.

[0036] Among them, the application program layer builds a general Windows CNC system framework based on the application program interface function library, Mi...

Abstract

The invention discloses an easily expansible numerical control system based on Windows. An application program layer in the system realizes the purpose of processing the data of the overall system; by using a driving program as a core and combining services provided by the kernel of the Windows operating system, a middle layer carries out data exchange with the application program layer through an independently established shared memory exchange area and two one-way annular buffer areas; and a bottom hardware layer is a hardware terminal board, is connected with a personal computer (PC) through a PCI bus, and is mainly responsible for providing accurate timing interruption and an instruction buffer area with 40 groups of units for the numerical control system. In the invention, the numerical control system is developed on the basis of an unique NC system framework which is formed by reforming an MFC in a large range, relates to a full-software numerical control system based on Windows, and solves the problem that the reconstruction property and the real-time property of the current open numerical control system based on the PC can not be combined easily.

Description

Technical field: [0001] The invention relates to a numerical control technology, in particular to an all-software numerical control system based on a Windows operating system and a modular design structure. Background technique: [0002] Manufacturing is a country's basic industry, which directly reflects a country's productivity level. Numerical control technology is an important means to improve product quality and labor productivity, representing today's advanced productivity. Therefore, the level of numerical control technology has become the main symbol to measure the modernization degree of a country's manufacturing industry. [0003] Although the traditional numerical control system performs well in terms of real-time performance, because it adopts a closed and special-purpose system structure, the biggest disadvantage of this structure is its poor openness. Perform scaling adjustments, such as adding new control algorithms and functions. [0004] At present, with ...
