Description

technical field [0001] The invention belongs to the category of control and adjustment, and in particular relates to the control of an open-structure numerical control system of a computer-guided secondary development simulation platform. Background technique [0002] The current CNC system basically has two modes, one is the closed structure CNC system of the traditional special-purpose single-chip processor mode, and the other is the open CNC system based on the industrial computer and the motion control card mode that is currently in the research and development stage. [0003] The traditional CNC system uses a dedicated single-chip microcomputer as the hardware core. The closed architecture shields all system technical details, and only provides users with fixed-function external general control interfaces. Users must select matching peripheral drive devices according to system requirements. CNC machine construction. Once the system i...

Problems solved by technology

As a general-purpose platform, the PC computer does not consider the particularity of NC machining in terms of the design of the underlying hardware and the operating system environment, so it is impossible to fundamentally build a NC platform

[0006] 2. The open CNC system in the industrial computer mode cannot guarantee real-time performance and reliability

Because the PC computer uses a general-purpose operating system during operation, it takes up a lot of system resources. Tasks that have nothing to do with NC machining may take up more work shares of the system. They interfere with the timely response of the system to on-site processing, reducing the The system's processing speed of important control events and increase the overhead of system operation, which will lead to system instability

[0007] 3. The cost of industrial computer mode CNC system is too high

A computer that can meet the speed requirements of CNC machining needs to invest at least several thousand yuan to be equipped with a motion control card, making it difficult to reduce the cost

[0008] 4. Since the control system does not have an independent open structure system, it must rely on the structure system and software framework of the PC computer, so it is destined to only reflect the secondary development in the form of a single function library, which requires an ordinary user or a machine tool operator Have a good programming foundation and computer hardware and software knowledge

And this is undoubtedly too much price for general improvement users, and sometimes it is not worth the loss

For advanced users, it is not enough to only provide function libraries.

In addition, the current development methods do not have a special friendly platform, nor a guided process suitable for the development of CNC functions to help users define functions. On the one hand, they cannot fully provide users with the structural advantages of an open CNC system. On the other hand, On the other hand, users who are inexperienced or not very clear about the required functions will take detours and even destroy the stability of the system
