Embodiment 1

[0015] A motion control card device for a flame cutting numerical control system, comprising: an upper computer IPC, the upper computer IPC is connected to a lower computer through a peripheral component expansion interface PCI, and the lower computer includes a motion control card, the The motion control card has pulse PULSE / direct reduced iron DRI, electronic control amplifier ECA / eddy current braking ECB / comprehensive energy consumption ECZ, local maintenance terminal LMT+ / local maintenance terminal LMT-, the PULSE / DIR is connected through pulse / direction The X / Y / Z-axis servo motor driver, the X / Y / Z-axis servo motor driver is connected to the ECA / ECB / ECZ through the encoder limit, and the X / Y / Z-axis servo motor driver is connected to A travel switch, the travel switch is connected to the LMT+ / LMT-.

Embodiment 2

[0017] The motion control card device for the flame cutting numerical control system described in embodiment 1, the upper computer IPC is used to run the developed numerical control flame cutting system upper computer control software, realizes the communication with the lower computer through the PCI bus , IPC drives the machine tool to complete the cutting process by invoking system resources. At the same time, as the man-machine interface of the CNC system, the IPC has the functions of setting system working parameters, displaying the running status, and tracking the cutting trajectory.

Embodiment 3

[0019] In the motion control card device for the flame cutting numerical control system described in embodiment 1, the lower computer part is mainly composed of two parts: a motion control card and a multi-function data acquisition card; wherein the motion control card outputs pulses and direction signals, Drive the X / Y / Z axis servo motor of the machine tool to interpolate the cutting torch along the processing path, obtain the phase signal of the encoder through the encoder feedback channel, and obtain the actual position of the cutting torch; the DI on the motion control card The channel LMT / LMT‐connected to the state of each limit switch, limits the movement of each axis to ensure that each axis moves within a reasonable range of travel and avoid accidents such as overtravel. The multi-function data acquisition card is mainly composed of two types of analog input channels and DI / O channels. The analog input channels are connected to various analog signal sensors. After A / D c...

Description

Technical field: [0001] The invention relates to a motion control card device used in a flame cutting numerical control system. Background technique: [0002] At present, there are mainly two types of operating systems for CNC systems on the market. One is a general-purpose operating system, commonly used such as DOS, Linux, Windows, etc. Among them, the Windows platform has been strongly supported by various hardware manufacturers, and they all provide complete hardware drivers under the Windows platform for their own products, and have rich software resources, but they are not suitable for flame cutting CNC systems. The other is the embedded real-time operating system, such as RTXC, VXWORKS, etc., which are powerful and practical, but the price is too expensive and the development is difficult. Invention content: [0003] The purpose of the present invention is to provide a motion control card device for flame cutting numerical control system with good openness and exp...
