[0057] Figure 1 is an optional flowchart of the engraving control method provided by the embodiments of the application, Figure 1 The method in the above embodiment can be applied to an engraving control device, and can include but is not limited to the steps S110 to S150.

[0058] In step S110, a model engraving file is acquired.

[0059] In step S120, the model engraving file is sent to an engraving machine, and a start engraving instruction is sent to the engraving machine.

[0060] In step S130, a video of a process of engraving a preset material according to the model engraving file is collected in response to the start engraving instruction, to obtain an engraving video.

[0061] In step S140, the engraving video is sent to a terminal device, and a first stop engraving instruction fed back by the terminal device according to the engraving video is received.

[0062] In step S150, the first stop engraving instruction is sent to the engraving machine, so that the engraving machine stops engraving according to the first stop engraving instruction.

[0063] The steps S110 to S150 shown in the embodiments of the application can enable the terminal device to acquire a video of laser engraving in real time by sending the engraving video to the terminal device, and determine information such as an engraving progress and an engraving effect according to the video. Meanwhile, the terminal device can remotely control the engraving machine to start or stop engraving. When the engraving video shows that the engraving effect is not good, the terminal device can immediately stop the engraving machine, thereby reducing material waste.

[0064] Please refer to Figure 2 In some embodiments, the step S110 can include but is not limited to the steps S210 to S220.

[0065] In step S210, the model carving pattern and the position information are obtained; the position information is used to indicate the position of the model carving pattern on the preset material.

[0066] In step S220, the model carving file is obtained according to the model carving pattern and the position information.

[0067] In step S210 of some embodiments, the carving control device has a USB interface, one end of a USB connecting line is inserted into the USB interface, and the other end is inserted into the interface at the corresponding position of the carving machine, so as to realize the connection between the carving control device and the carving machine, to send control commands to the carving machine or read the feedback of the carving machine to the control commands. The carving control device is provided with a carving machine indicator light, which is used to display whether the carving control device is connected to the carving machine. For example, if the carving machine indicator light shows a stable red color, it means that the carving control device is connected to the carving machine; if the carving machine indicator light shows a flickering red color, it means that the carving control device is not connected to the carving machine. Specifically, the carving control device sends a connection request to the carving machine through the USB connecting line, the carving machine tries to connect the carving control device in response to the connection request, and feeds back the connection result to the carving control device, so that the carving control device switches the display of the carving machine indicator light according to the connection result. If the connection result indicates that the carving control device is connected to the carving machine, the carving machine indicator light shows a stable red color. If the connection result indicates that the carving control device is not connected to the carving machine, the carving machine indicator light shows a flickering red color. The carving control device also has a data interface through which the carving control device and a computer are connected, and the lightburn carving software is deployed on the computer. The model carving pattern is a pattern that needs to be carved on the preset material. The position information is the carving position of the model carving pattern on the preset material. It can be understood that the data stored on the carving control device can be transmitted to the computer through the data interface. The model carving pattern is imported into the lightburn software, the model carving image is edited, and the position of the model carving pattern on the preset material is set, and the model carving pattern and the position information are transmitted to the carving control device through the data interface.

[0068] In step S220 of some embodiments, the model carving pattern and the position information are used as the model carving file, and the carving control device transmits the model carving file to the carving machine through the USB interface, so that the carving machine carves the preset material according to the model carving file. The model carving file is a file in gcode standard.

[0069] In addition to the model carving pattern and the position information, the model carving file also includes the carving power, the carving speed, and the carving mode, wherein the carving power is the output power of the laser head of the carving machine, the carving speed is the moving speed of the laser head of the carving machine, and the carving mode is cutting carving, concave mold carving, etc.

[0070] Through the above steps S210 to S220, the engraving position of different shaped preset materials can be located so that the engraving machine can engrave the model and engrave the graphic at the engraving position of the preset material.

[0071] In step S120 of some embodiments, the engraving control device uses a DSP main control chip for multi-task instruction processing and video encoding processing. The engraving control device is equipped with a WIFI module, which is communicatively connected to the DSP main control chip. Through the WIFI module, the engraving control device can connect to a WIFI network, enabling remote transmission of video and command streams. The WIFI module includes an adjustable antenna, which can enhance wireless signal transmission by adjusting the antenna's direction. Simultaneously, the engraving control device is equipped with a WIFI indicator light, which directly indicates whether the engraving control device is connected to the WIFI network. For example, if the WIFI indicator light displays a stable green, it indicates that the engraving control device has successfully connected to the WIFI network; if the WIFI indicator light displays a flashing green, it indicates that the engraving control device is not connected to the WIFI network. The model engraving file can be remotely sent to the engraving machine via a terminal device, and a start engraving command can be sent to the engraving machine, enabling remote control of the engraving machine. For example, the model engraving file and the start engraving command can be sent to a wireless router via a mobile application or computer browser. After forwarding by the wireless router, the engraving control device receives the model engraving file and the start engraving command, and then sends the model engraving file and the start engraving command to the engraving machine. The model carving file and start carving command can also be sent through a computer connected to the carving control device.

[0072] In step S130 of some embodiments, Lightburn software is deployed on the computer. The computer is connected to the engraving machine, and the positioning function of Lightburn software, along with certain calibration steps, allows for point-to-point engraving or cutting of materials of different shapes and patterns. However, this method only achieves positioning and cannot remotely monitor the engraving machine. To achieve remote monitoring, the engraving control device in this embodiment includes a lens, infrared LEDs, and a focus knob. The lens is used for image acquisition and is a camera using a CMOS image sensor. The lens is communicatively connected to the DSP main control chip, enabling the DSP main control chip to encode the image acquired by the lens. The infrared LEDs provide compensation light to the lens, and the focus knob adjusts the lens focal length. The engraving control device can be positioned using a tripod to capture the laser engraving process. By adjusting the focus knob and using the infrared LEDs for light compensation, the engraving control device can acquire high-resolution engraving video, allowing for remote monitoring of the laser engraving process based on the engraving video. The engraving video is a video of the engraving machine engraving the preset material according to the model engraving file in response to the start engraving command.

[0073] While it's possible to remotely monitor the laser engraving process using a camera with Wi-Fi connectivity, this method doesn't allow for interconnection between the camera and the engraving machine, thus preventing remote control. This embodiment of the application achieves remote monitoring by connecting the camera and the engraving machine via a USB cable and transmitting engraving video and commands through a Wi-Fi module.

[0074] Please see Figure 3 In some embodiments, after step S130, the engraving control method may also include, but is not limited to, steps S310 to S320:

[0075] Step S310: Receive the video sampling interval sent by the terminal device;

[0076] Step S320: Perform video sampling on the engraving video according to the video sampling interval to obtain the sampled engraving video.

[0077] In step S310 of some embodiments, laser engraving typically takes a long time, resulting in a long video duration for the engraving video. This embodiment shortens the video duration by setting a video sampling interval to sample the engraving video, generating a time-lapse video with a single click. The video sampling interval is sent by the receiving terminal device. This interval can be sent remotely by the terminal device or at close range by a terminal device connected to the engraving control device and equipped with Lightburn software.

[0078] In step S320 of some embodiments, the engraved video includes multiple video frames, and one or more video frames are acquired at each video sampling interval to obtain the sampled engraved video. For example, if the engraved video is 3 hours long and the video sampling interval is 20 minutes, then one video frame of the engraved video is acquired every 20 minutes to obtain the sampled engraved video.

[0079] Understandably, it's also possible to achieve one-click generation of time-lapse videos without sampling the sculpting video. Specifically, the camera captures one image at each video sampling interval, and multiple images are sorted in ascending order of capture time to obtain the sampled sculpting video.

[0080] Through steps S310 to S320 above, a time-lapse video can be generated with one click, allowing users to quickly understand the entire laser engraving process.

[0081] Please see Figure 4 In some embodiments, after step S130, the engraving control method may also include, but is not limited to, steps S410 to S430:

[0082] Step S410: Evaluate the carving progress based on the carving power, the size of the carved file, and the size of the target file to obtain carving progress data;

[0083] Step S420: Evaluate the engraving time based on the engraving power, the size of the already engraved file, and the size of the target file to obtain the remaining engraving time;

[0084] Step S430: Send the carving progress data and remaining carving time to the terminal device.

[0085] In step S410 of some embodiments, to enable users to remotely view the laser engraving progress, the engraving progress is evaluated based on the engraving power, the size of the already engraved file, and the target file size to obtain engraving progress data. During laser engraving, the engraving speed and engraving position coordinates change rapidly, so the engraving progress data may not include the engraving speed and engraving position coordinates. The size of the already engraved file refers to the storage space occupied by the completed portion of the model engraving graphic, and the target file size refers to the storage space occupied by the model engraving graphic. Subtracting the target file size from the already engraved file size yields the remaining engraved file size, which represents the storage space occupied by the un-engraved portion of the model engraving graphic. The engraving power, the size of the already engraved file, the target file size, and the remaining engraved file size are used as the engraving progress data.

[0086] In step S420 of some embodiments, the carving time is evaluated based on the already carved file size and the target file size to obtain the remaining carving time. The remaining carving time is the carving time required for the uncarved portion of the model's carved graphic. Specifically, the remaining carved file size is obtained by subtracting the target file size from the already carved file size, and the carved time corresponding to the already carved file size is obtained. The carved time is the carving time consumed for the completed portion of the model's carved graphic. The ratio of the carved time to the already carved file size is used as the carving time per unit file size, which represents the time required to carve a unit file size. The remaining carving time is obtained by multiplying the carving time per unit file size by the remaining carved file size.

[0087] or,

[0088] The remaining carving time is estimated based on the carving power, the size of the already carved file, and the target file size. Specifically, the carving power is multiplied by the carved time to obtain the carved energy, which represents the energy required to carve the completed portion of the model's graphic. The carved energy is divided by the carved file size to obtain the carving energy per unit file size, which represents the energy required to carve a unit of file size. The carving energy per unit file size is multiplied by the remaining carved file size to obtain the remaining carving energy, which represents the energy required to carve the unfinished portion of the model's graphic. The remaining carving energy is divided by the carving power to obtain the remaining carving time.

[0089] In step S430 of some embodiments, the DSP main control chip sends the engraving progress data and the remaining engraving time to the wireless router via the WIFI module. The wireless router then forwards the engraving progress data and the remaining engraving time to the terminal device, so that the user of the terminal device can obtain the engraving progress of the laser engraving.

[0090] Through steps S410 to S430 above, the laser engraving progress can be obtained remotely via a mobile application or computer browser.

[0091] Please see Figure 5 In some embodiments, after step S130, the engraving control method may also include, but is not limited to, steps S510 to S520:

[0092] Step S510: Send the engraving video to the terminal device and receive the engraving parameters fed back by the terminal device based on the engraving video;

[0093] Step S520: Send the engraving parameters to the engraving machine so that the engraving machine can adjust its equipment parameters according to the engraving parameters.

[0094] In step S510 of some embodiments, the laser power of the engraving machine is typically greater than 5W. To ensure smooth laser engraving and reduce accidents, the user must remain in the room where the engraving machine is operating to monitor it. Currently, engraving machines do not have network connectivity, making remote monitoring of the laser engraving process impossible, and users cannot know the engraving effect. This application embodiment uses an engraving control device to send the engraving video to a terminal device, allowing the user of the terminal device to view the engraving video anytime, anywhere, and understand the laser engraving effect remotely. The DSP main control chip encodes the engraving video, compresses the encoded engraving video via a WIFI module, and transmits it to a wireless router. The wireless router then sends the engraving video to a server, which in turn sends it to the terminal device. The terminal device decodes the engraving video to view it. The engraving video demonstrates the laser engraving effect. If the user of the terminal device is not satisfied with the engraving effect, they can adjust the engraving parameters and send these parameters to the engraving control device. The engraving control device receives the engraving parameters from the terminal device based on the engraving video. The engraving parameters include engraving speed and engraving intensity. It should be noted that the process of sending the engraving parameters to the engraving control device can be referred to in step S120, and will not be repeated here.

[0095] In step S520 of some embodiments, the DSP main control chip sends engraving parameters to the engraving machine so that the engraving machine adjusts its equipment parameters according to the engraving parameters, and adjusts the equipment parameters of the engraving machine to the specific values ​​of the engraving parameters sent by the terminal device.

[0096] Through steps S510 to S520 above, the engraving speed, engraving intensity and other engraving parameters of the engraving machine can be remotely controlled.

[0097] In step S140 of some embodiments, the engraving video is sent to the terminal device, and a first stop engraving command is received from the terminal device based on the engraving video. The first stop engraving command is used to cause the engraving machine to remove the laser head and stop the engraving machine from working. When the engraving effect shown in the engraving video is not good, the engraving machine can be remotely controlled to stop working through the first stop engraving command. The process of remotely sending the engraving video to the terminal device can be referred to step S510, and will not be repeated here.

[0098] Please see Figure 6 In some embodiments, step S140 may include, but is not limited to, steps S610 to S620:

[0099] Step S610: Obtain the video duration of the engraving video;

[0100] In step S620, if the video duration is less than the preset duration, the engraved video is stored in the preset storage space until the video duration is greater than or equal to the preset duration. Then, the engraved video is read from the preset storage space and sent to the terminal device.

[0101] In step S610 of some embodiments, in order to reduce the waste of network resources and avoid frequent transmission of the engraving video from the engraving control device to the remote terminal device, the embodiments of this application limit the video duration of the engraving video. Specifically, the video duration of the engraving video is obtained.

[0102] In step S620 of some embodiments, the engraving control device is equipped with an SD memory card for storing engraving videos. The preset storage space is the storage space of the SD memory card. If the video duration is less than the preset duration, the engraving video is stored on the SD memory card until the duration of the engraving video stored on the SD memory card is greater than or equal to the preset duration. Then, the engraving video is read from the SD memory card and sent to the terminal device.

[0103] By using steps S610 to S620, the network bandwidth occupied by frequently sending engraving videos can be reduced, thus avoiding the waste of network resources.

[0104] Please see Figure 7 In some embodiments, after step S140, the engraving control method may also include, but is not limited to, steps S710 to S740:

[0105] Step S710: Receive flame light source information triggered by the engraving machine catching fire;

[0106] Step S720: Trigger an early warning based on the flame source information and generate early warning information;

[0107] Step S730: Send the warning information to the terminal device and receive the second stop carving command from the terminal device based on the warning information;

[0108] Step S740: Send a second stop carving command to the carving machine so that the carving machine stops carving according to the second stop carving command.

[0109] In step S710 of some embodiments, if the laser power of the engraving machine is set improperly or the engraving machine malfunctions, the engraving machine may catch fire. This embodiment of the application installs a flame sensor and a Bluetooth module on the engraving machine. The flame sensor and Bluetooth module are communicatively connected, and the flame sensor detects a fire source or a light source within a preset wavelength range. The flame source information is the fire source information or light source information measured by the flame sensor. When a flame or light source triggers the flame sensor to send the measured flame source information to the engraving control device via the Bluetooth module, the engraving control device receives the flame source information via its own Bluetooth module.

[0110] In step S720 of some embodiments, the engraving control device further includes a buzzer, which is triggered to alarm according to the flame light source information and generates a warning message. The warning message is used to notify the user of the terminal device that the engraving machine is malfunctioning.

[0111] In step S730 of some embodiments, a warning message is sent to a terminal device so that the user of the terminal device can receive timely notification of an abnormal operation of the engraving machine. A second stop engraving command is received from the terminal device based on the warning message; this second stop engraving command is used to stop the engraving machine from operating. It is understood that users sometimes cannot respond to warning messages in a timely manner. After a warning is triggered based on the flame source information, the engraving control device can automatically generate a second stop engraving command to control the engraving machine to stop engraving, without needing to send the second stop engraving command through the terminal device.

[0112] In step S740 of some embodiments, a second stop carving command is sent to the carving machine so that the carving machine stops carving according to the second stop carving command, thereby protecting the carving machine and extending its service life.

[0113] Through steps S710 to S740 above, when the engraving machine malfunctions, the terminal device can promptly obtain information about the engraving machine's malfunction and take measures to reduce the occurrence of accidents during laser engraving.

[0114] In step S150 of some embodiments, a first stop carving command is sent to the carving machine so that the carving machine stops carving according to the first stop carving command.

[0115] In some embodiments, the engraving control device also includes a microphone. The microphone collects sound during the laser engraving process. Alternatively, it can send voice commands to the engraving machine to achieve voice control. In some embodiments, the engraving control device also has a power interface, allowing it to be charged by connecting a power cord to a power source when its battery is low.

[0116] The engraving control device of this application embodiment is an integrated multi-functional device. After network configuration, remote monitoring of the engraving machine can be achieved. It also features functions such as positioning engraving, flame sensor alarm, and automatic generation of time-lapse video. Through the engraving control device, users can remotely monitor the engraving machine via a mobile application or PC browser. If the engraving or cutting effect is unsatisfactory, the engraving or cutting work can be paused or stopped at any time. If the laser power setting is unreasonable or an engraving abnormality causes the engraving machine to catch fire, an alarm will sound via buzzer, the laser head will be automatically moved, and the user will be notified via the APP, effectively protecting the engraving machine. The engraving control device of this application embodiment is simple and convenient, requiring no complex configuration, and is plug-and-play. It can generate time-lapse video with one click and, combined with a flame sensor, achieve flame detection, alarm, and push notification functions. Users can upload gcode files to their mobile phones and computers for engraving or cutting, and view real-time video and control the engraving machine on both devices. Furthermore, it can perform positioning engraving or cutting of materials of different shapes using Lightburn software on a connected computer.
