[0002] Laser engraving machine is an advanced equipment that uses laser to engrave the materials that need to be engraved. Laser engraving machine is different from mechanical engraving machine and other traditional manual engraving methods. Mechanical engraving machine uses mechanical means, such as diamond and other extremely hard materials to engrave other things. Laser engraving machine uses the heat energy of laser to engrave materials. For example, as shown in the laser engraving machine with Chinese patent application number CN202220837122.6, the terminal establishes an NFC connection with the laser engraving machine, and the control calculation module receives the transmission data sent by NFC and performs identification and verification to obtain the laser engraving data. Then, according to the laser engraving command header in the laser engraving data, the compressed data behind the laser engraving command header is decompressed to obtain the command and data sent by the terminal, and the state of the electromagnet in the commutation slot, the rotation slot and the adjustment slot is controlled according to the command and data, so as to complete the engraving task; making the data transmission method between the host computer and the engraving machine efficient and simple.
