Description

technical field [0001] The invention belongs to the category of control and regulation, and in particular relates to computer remote network monitoring and open control of secondary development functions. Background technique [0002] The current CNC system basically has two modes, one is the closed structure CNC system of the traditional dedicated single-chip processor mode, and the other is the open CNC system based on the industrial computer and motion control card mode that is currently in the research and development stage. [0003] The traditional mode of numerical control 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. Realize the construction of CNC machine tools. Once the system is fin...

Problems solved by technology

Since this kind of network does not consider the transmission requirements of large-flow signal data streams for CNC machining and status monitoring, it limits the remote network application capabilities of the system in terms of speed, and is basically only suitable for program transmission between systems.

[0009] Finally, 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 this single function library, which requires an ordinary user or a Machine tool operators have a good programming foundation and computer hardware and software knowledge, which is undoubtedly too much for users who only need general improvement, and sometimes it is not worth the candle

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

In addition, the current development methods do not have a special and friendly platform, and there is no guided process suitable for the development of CNC functions to help users define functions. On the one hand, users cannot make full use of the structural advantages of the open CNC system; Make detours for inexperienced users or users who are not very clear about the required functions or even destroy the stability of the system
