Embodiment 1

[0028] The invention discloses a control system of a numerical control cutting machine. The whole system is divided into the following modules: ARM processor module, memory module, power supply module, man-machine interaction module, communication interface module, D / A conversion module, CPLD / FPGA modules and input and output modules. Among them, the ARM processor is the control core of the system, which is responsible for running the control software of the numerical control system. Memory modules are used to store programs and data. The memory of this system includes EPROM, SDRAM, SRAM and NAND-Flash. Among them, EPROM is used to store system programs; SDRAM is used to store programs and data when the system is running; SRAM is used to store important real-time data when power is suddenly lost; NAND -Flash is used to store the user's CNC machining program.

[0029] Specific as figure 1 As shown, the ARM processor, EPROM, SDRAM, SRAM, NAND-Flash, CPLD, FPGA, and USB inter...

Abstract

The invention belongs to the technical field of numerical control cutting machines and particularly discloses a control system for a numerical control cutting machine. The control system comprises an ARM processor module, a storage module, a power module, a human-computer interaction module, a communication interface module, a digital to analog (D / A) conversion module, a complex programmable logic device / field programmable gate array (CPLD / FPGA) module and an input output module. An embedded system based on an ARM processor and a muC / OS-II is adopted, and real-time performance, stability and reliability of the numerical control cutting machine are improved.

Description

technical field [0001] The invention belongs to the technical field of numerical control cutting machine control, and in particular relates to a control system of a numerical control cutting machine. Background technique [0002] At present, the control system of CNC cutting machine is mainly divided into two categories: the open CNC system based on PC and the closed CNC system based on single-chip microcomputer. The numerical control system based on PC, on the basis of general PC, adopts special motion control card to control the motion of the motor. The motion control algorithm has been implemented in the motion control card, and some application interfaces are also provided to the outside world. However, the main shortcomings of this type of numerical control system are: (1) Due to the volume limitation of the PC, this type of numerical control system cannot be installed in a micro or small system with strict volume requirements; and it needs to be bundled with a compute...
