PC-based digital control system of groove cutting machine

Abstract

The invention provides a PC-based digital control system of a groove cutting machine. The digital control system comprises an industrial control computer and an input / output interface card. The industrial control computer is provided with a motion control card, a PCI bus and a universal external interface. The motion control card is installed on the PCI bus of the industrial control computer; the input / output interface card is connected to the PCI bus of the industrial control computer via the motion control card and connected with a three-dimensional translating shaft, a rotary shaft, a swaying shaft, an input interface and an output interface. The motion control card comprises DSP and FPGA and works the platform of the Windows system. The PC-based digital control system of the groove cutting machine is suitable for users' usual operation habits; each part is independent and the partial hardware can be purchased from the market and used as the constituent parts; compared with the present control system, the performance is improved, the cost is reduced and the assembling, usage and upgrading are simple.

Description

technical field [0001] The invention relates to a control system, in particular to a PC-based digital control system for a bevel cutting machine. Background technique [0002] According to the design or process requirements, the groove of a certain geometric shape processed and assembled on the part of the weldment to be welded is called the groove. Groove is mainly used to weld the workpiece to ensure the degree of welding. Generally, the surface is processed by machining method. [0003] At present, the digital controller of the bevel cutting machine is mainly based on the embedded closed numerical control system, and the motion control algorithm is realized by using the single-chip microcomputer or ARM chip as the main control chip. The following deficiencies: [0004] (1) The computing power of embedded systems is poor. Taking ARM Cortex-A8 as an example, the computing power of a CPU with a main frequency of 720MHz is only 1 / 20 of that of an Intel Atom N270 1.6GHz CPU....

AI Technical Summary

Problems solved by technology

[0004] (1) The computing power of embedded systems is poor. Taking ARM Cortex-A8 as an example, the computing power of a CPU with a main frequency of 720MHz is only 1 / 20 of that of an Intel Atom N270 1.6GHz CPU. The computing power of motion control interpolation operations is relatively low. Large, computing power has become the biggest bottleneck restricting the development of embedded;

[0005] (2) The operating habit support of embedded systems is not as good as that of PC systems. Traditional PCs have already entered every household, and users are very familiar with and accept the operation methods of PCs;

[0006] (3) It is difficult to integrate third-party tools on the embedded system. For example, the CAM software supporting the CNC system can run normally on the PC, but it is difficult to realize on the embedded system;

[0007] (4) Embedded system development is more difficult than software development on PC. Since the development is carried out on an ordinary PC, cross-compilation is required for embedded development, which will bring great trouble to software debugging and error correction.
