Embodiment Construction

[0094] Now with 3500W high power shaft fast flow CO 2 The laser control system is taken as an example to illustrate the implementation of the present invention. The programmable controller (Siemens CPU224) produced by Siemens and the touch screen produced by Delta are used as the main components, together with the peripheral electrical components and detection components to form the hardware of the control system, and the PLC and touch screen software that can realize the aforementioned functions are developed. Control objectives were successfully achieved. See Figure 11 for the PLC I / O function table, and Figure 12 for the Siemens CPU224 specific hardware I / O address table. Its control method is the same as the aforementioned method.

Abstract

A programmable logic controller (PLC) method for controlling a high-power fast axial-flow CO2 laser by use of touch screen includes such steps as detecting working condition of the laser, turning on the laser, vacuumizing, turning on the part controlled by high-voltage power supply, opening gas inlet valve and sucking regulation valve, examining state of frequency converter, turning on fan, running authorization program, closing gas inlet valve, determining gas consumption, controlling regulation valve, checking the high-voltage authorization, turning on high-voltage power supply, regulating laser power, closed-loop feedback, and self-test of the laser.

Description

technical field [0001] The invention relates to a control method, in particular to a high-power axial fast-flow CO 2 Laser PLC control method. Background technique [0002] High power shaft fast flow CO 2 The laser is an advanced kilowatt-level laser. At present, it is generally controlled by a single-chip microcomputer or a programmable controller. However, there are many analog / digital circuit boards in the control system, and the reliability is poor. The dialogue interface of the drone is not fully functional and difficult. operational issues. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies in the background technology, and propose a fully modularized, digital high-power axial flow CO that can conduct man-machine dialogue through a touch screen. 2 The PLC control method of the laser eliminates all analog / digital circuit boards, which makes the control system more complete and has higher control performance, while t...
