Problems solved by technology

The problem with this architecture is that the physical wiring is complex, the real-time communication and security reliability are poor, the performance is difficult to improve, and the cost is high
[0003] Another difficulty of the multi-channel multi-axis motion system is the cooperative programming problem of multi-machine operation
Control motion control is actually a concurrent mode in which multiple channels run at the same time, and the method of using PLC programming is inefficient

Embodiment Construction

[0014] The specific implementation of the present invention will be described below with an embodiment of the motion control system.

[0015] figure 1 It is a structural diagram of an embodiment of the motion control system, including: a communication module, an external storage module, a core control module, an instruction-code parsing module, an interpolation calculation module, a multi-channel motor driver, and an input-output port control module;

[0016] The existing motion control system instruction code parsing module integrates a G code or other language code interpreter, such as a robot AL language interpreter. As a lightweight language, the Lua scripting language is widely used in the computer field, but it is not suitable for the control field because it does not support shaping data. But with the latest version supporting shaped data, the barriers to using the Lua language in the control field have been removed.

[0017] The present invention integrates the Lua v...

Abstract

The invention relates to a motion control system. A Lua virtual machine is integrated in an instruction code analysis module, so the traditional language codes can be executed and Lua codes also can be executed; robot language or G codes are embedded into the Lua codes in the form of a character string; and the coroutine function of the Lua language is used, each path of motion control corresponds to a coroutine, so that one path or more paths of motion control are controlled. The control system is suitable for multi-path mechanical arm control which needs complicated control.

Description

technical field [0001] The invention relates to the technical field of numerical control, in particular to a motion control system. Background technique [0002] In factory-level automation control occasions, it is often faced with the problem of cooperative control of multiple (2-16) multi-axis (3-6 axis) manipulators. The solution implemented is that each manipulator is equipped with a control system, the manipulators are connected and communicated through the bus, and the cooperative control is realized through the PLC system. The problem of this architecture is that the physical wiring is complex, the real-time communication and security reliability are poor, the performance is difficult to improve, and the cost is high. [0003] Another difficulty of multi-channel multi-axis motion system is the cooperative programming problem of multi-machine operation. Control Motion control is actually a concurrent mode with multiple channels running at the same time, and the metho...
