Problems solved by technology

The existing open CNC system is divided into two categories, one is based on the structure of industrial computer and motion control card, and the other is based on the structure of embedded single-board computer with more than 32-bit CPU plus motion control card, and the motion control card Generally used to ensure the real-time performance of the CNC system, but because the motion control card is relatively expensive, the price of the entire CNC system is relatively high
And the hardware part of the control card is difficult to achieve the purpose of making the open CNC system customized according to user needs, resulting in a waste of resources

Abstract

The invention relates to an open recombinable soft numerical control system. Said system is formed from 32-bit and more than 32-bit embeddent single board computer, digital IO interface card and recombinable development platform consisting of software package. The display controller in the single board computer and bus controller are connected with CF card, and the running software can utilize digital interface board to implement real-time control of machine tool. Said recombinable development platform includes systematic requirement description device/analyzer/automatic modelling device, function block editor, function block connector, function block compilation device, function block library, software movement control and softawre PLC module library, fault diagnosis module library, man-machine interactive function module library, embedded object connection process control server module library, hardware drive program library and embedded operation system custom device.

Description

technical field [0001] The invention belongs to a machine tool numerical control system, in particular to an open reconfigurable soft numerical control system based on Windows CE.NET. Background technique [0002] Machine tool numerical control systems are divided into two categories, one is closed structure numerical control system, and the other is open numerical control system. The closed CNC system uses a dedicated single-chip processor. Different manufacturers use different software, which is not interchangeable. Once the system is generated, the system provides users with fixed functional modules. If users need to add new functions, It must be completed by the manufacturer, and the development cycle is long and the efficiency is low; the open numerical control system is a digital controller based on a unified architecture, standard development specifications and a general computer system platform. Due to its open and standardized structural characteristics, it can int...
