Abstract

The invention discloses a design method for a control structure of a hardware-in-loop numerical control system. The method comprises the following steps of: constructing a simulation running environment of CNC (Computer Numerical Control) in the numerical control system according to the function properties and the control demands of the numerical control system; connecting the CNC with the simulation running environment by a field bus, and conducting two-way real-time and reliable data communication; executing a process testing program by the CNC, and conducting simulation processing test on a whole control function module or a whole specific function module in the CNC; according to the processing control information in the test process, simulating the control operations of the devices (except the CNC) in the numerical control system, and displaying the processing process of workpiece; and verifying whether the functions and the performances of the CNC meet the requirements or not according to the processing form and the test information of the workpiece. According to the method, the application demands such as the tests of function modules and the whole control functions of the system in the system development process can be met, the reliability of the system development is improved, the risk and the cost for the system test is reduced, and the test time is shortened.

Description

technical field

[0001] The invention relates to a design method of a numerical control system structure, in particular to a design method of a control structure of a hardware-in-the-loop numerical control system. Background technique

[0002] The CNC system is mainly composed of two parts: system software and hardware devices. Wherein, the hardware device mainly includes: a numerical control device (Computer Numerical Control, CNC for short), an input / output device, a motion drive device, and an electrical logic control device and other hardware devices. CNC is the control core of the whole system, and communicates with other control devices through designated interfaces to coordinate the overall control functions.

[0003] With the continuous introduction of new control functions and hardware devices, the development and design process of CNC is becoming more and more complicated. On the one hand, new control algorithms, synchronization technology, hardware equipment, etc...
