The PLC slow control system comprises a PLC module, a three-dimensional angle control module, a door opening and closing control module, a laser power supply control module, a communication module and a power supply module, one end of the PLC module is connected with one end of the communication module, the other end of the PLC module is connected with the three-dimensional angle control module, the door opening and closing control module, the laser power supply control module and the power supply module, and the other end of the communication module is connected with the PLC module; the PLC module is used for controlling the whole system and collecting and transmitting data; the three-dimensional angle control module is used for controlling the laser turntable to realize horizontal rotation, pitching rotation and angular position adjustment; the door opening and closing control module is used for controlling a door to shield or cover the laser; the laser power supply control module is used for controlling a power supply to be turned off to realize laser power supply control; and the communication module is used for realizing communication connection between the PLC module and a local PC (Personal Computer). The system is convenient to use, simple in programming, strong in function, high in cost performance, high in reliability, strong in anti-interference capability, small in workload of system design, installation and debugging, and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of PLC control, in particular to a laser calibration PLC slow control system. Background technique [0002] Laser processing plays an important role in industrial processing. The use of lasers for material surface heat treatment, metal welding, and metal or non-metal cutting will be the trend of advanced processing today and in the future. Lasers have the advantages of compact structure, high beam quality, low optical loss, high thermal stability, and low gas consumption, and are widely used in laser processing fields such as laser cutting and laser welding. In order to ensure the safe and orderly work of each module of the laser and the smooth progress of industrial production, it is very important to design a safe and reliable control system for the laser. [0003] The key to laser control system design is the system's anti-interference ability, reliability and human-computer interaction. All circuit uni...
