Description

Technical Field

[0001] This invention relates to the field of laser measurement and calibration technology, and in particular to an intelligent laser marking and control system for correcting polarization and its usage. Background Technology

[0002] A laser dot meter is an instrument widely used in building decoration, engineering surveying, and indoor calibration. Its main function is to provide a visual reference benchmark for tasks such as wall verticality calibration, floor level measurement, and right-angle positioning by emitting a laser beam. Traditional laser dot meters typically use a fixed laser emission structure, relying on manual visual inspection and adjustment to complete the calibration work.

[0003] However, traditional laser dotting instruments have significant shortcomings in practical use. First, when calibrating the verticality of walls or the horizontality of window sills, operators need to repeatedly move the instrument or use a lifting platform to adjust the height and direction of the laser beam. This process is cumbersome and time-consuming, especially in situations requiring multi-point calibration, where inefficiency is particularly pronounced. Second, when the calibration target is located far from the instrument, operators often need to repeatedly adjust the instrument's direction, observing and correcting as they go, making it difficult to quickly and accurately align the laser beam with the target point, further reducing work efficiency.

[0004] To address this, the present invention proposes an intelligent laser marking and control system and its usage method. By organically combining posture recognition, position perception, dynamic tracking and automatic control, it realizes intelligent automatic alignment and precise correction of the laser beam, greatly simplifies the operation steps, improves the efficiency and accuracy of calibration operations, and enhances the intelligence level and on-site adaptability of the equipment. Summary of the Invention

[0005] The technical problem to be solved: the problem of low efficiency and poor precision caused by repeated manual adjustments.

[0006] To address the shortcomings of existing technologies, this invention provides an intelligent laser marking and control system and its usage method, thereby solving the technical problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A control system for an intelligent laser dotting device for correcting deviations includes a lower-level computer and a higher-level computer.

[0009] The lower-level machine includes:

[0010] An attitude sensor, installed within the positioning component, is used to detect the placement attitude of the positioning component;

[0011] Position sensor, used to detect the relative position between the main body and the positioning component;

[0012] A motion sensor, installed within the positioning component, is used to detect the displacement trajectory of the positioning component during movement.

[0013] Control sensors, installed inside the main body, are used to monitor the main body's own state;

[0014] Communication equipment used for data transmission;

[0015] The host computer includes:

[0016] The analysis unit is used to receive and parse attitude and position information to determine the type of laser beam that needs to be adjusted and the initial adjustment amount.

[0017] The control unit is used to generate control commands based on the analysis results to drive motor one and motor two to operate.

[0018] The correction unit receives real-time motion data uploaded by the motion sensor, calculates the following compensation amount, and sends it to the control unit, so that the laser beam follows the positioning component in real time.

[0019] In one possible implementation, an attitude sensor is used to determine whether the positioning component is in a vertical or horizontal state and sends the attitude information to the host computer via a communication device; the motion sensor uses a combination of MEMS accelerometer and gyroscope to continuously collect the instantaneous acceleration and angular velocity data of the positioning component at a sampling frequency of not less than 50 times per second, and uploads it to the correction unit of the host computer via a communication device.

[0020] In one possible implementation, the control sensors include a tilt sensor for detecting the levelness of the main body and an encoder for monitoring the rotation angles of motor one and motor two; the position sensor acquires the orientation and distance information of the positioning component relative to the main body through wireless ranging or signal angle measurement.

[0021] In one possible implementation, the analysis unit determines the orientation based on the attitude information: if it is in a vertical state, the vertical beam emitted by laser emitting device one and laser emitting device two is adjusted; if it is in a horizontal state, the horizontal beam emitted by laser emitting device three is adjusted.

[0022] In one possible implementation, the control unit corrects the rotation of motor one and motor two in real time based on the feedback signal from the encoder to ensure positioning accuracy.

[0023] In one possible implementation, the correction unit performs integral calculations and filtering on the acceleration and angular velocity data uploaded by the motion sensor to calculate the displacement vector and direction change of the positioning component, and calculates the angle compensation amount of motor one and motor two accordingly, which is then executed by the control unit for following adjustment.

[0024] In one possible implementation, an intelligent laser dotting device for correcting deviations, equipped with the aforementioned control system, includes a base and a main body rotatably connected to the top of the base, with a motor fixedly installed inside the base.

[0025] The main body is fixedly equipped with laser emitting device one and laser emitting device two, which are set perpendicular to each other and are used to emit vertical beams;

[0026] A laser emitting device is rotatably connected to the top of the main body, used to emit a horizontal beam;

[0027] A second motor is fixedly installed inside the main body, and a gear set is installed between the output end of the second motor and the third laser emitting device.

[0028] A positioning component is movably connected to one side of the base. The positioning component is equipped with a level tube and has an electrical plug for electrical connection with the main body.

[0029] In one possible implementation, the method of using an intelligent correction laser dotting device applied to a control system as described above includes the following steps:

[0030] S1. Place the main body in the working area, remove the positioning component and attach it to the surface of the target to be tested;

[0031] S2. The attitude sensor detects the placement attitude of the positioning component and sends it to the host computer via the communication device;

[0032] S3. The position sensor acquires the preliminary orientation and distance information of the positioning component relative to the main body and sends it to the host computer;

[0033] S4. The analysis unit determines the type of wire harness to be adjusted and the initial adjustment amount based on the attitude information and position information, and the control unit drives motor one and motor two to perform initial alignment.

[0034] S5. The operator moves the handheld positioning component on the target surface, and the motion sensor collects the displacement trajectory in real time and uploads it to the correction unit.

[0035] S6. The correction unit calculates the following compensation amount, and the control unit drives motor one and motor two to make the laser beam follow the movement of the positioning component in real time.

[0036] S7. The operator observes the adhesion between the laser line and the target surface, and stops moving when they are perfectly aligned to complete the calibration.

[0037] Beneficial effects compared to existing technologies:

[0038] In this solution, by embedding an attitude sensor within a detachable positioning component, automatic identification of the calibration target type is achieved, eliminating the need for manual judgment of wall verticality or windowsill horizontality. The introduction of a position sensor enables preliminary perception of the positioning component's spatial position relative to the main body, providing rapid target orientation for the main body. By adding a motion sensor within the positioning component and setting up a correction unit in the host computer, a dual calibration mechanism of "preliminary positioning + fine tracking" is constructed, enabling real-time dynamic tracking of the laser beam during the operator's handheld component micro-movement. Through real-time calculation of motion sensor data by the correction unit and closed-loop feedback control of the control unit, iterative approximation calibration through human-machine collaboration is achieved, effectively compensating for the accuracy limitations of single position measurements and solving the inefficiency and insufficient accuracy problems caused by the repeated instrument movement and manual laser head adjustment required by traditional laser dotting instruments. Ultimately, through the organic combination of attitude recognition, position perception, dynamic tracking, and automatic control, intelligent automatic alignment and precise correction of the laser beam are achieved, greatly simplifying the operation steps, improving the efficiency and accuracy of calibration operations, and enhancing the equipment's intelligence and field adaptability.

[0051] To more clearly illustrate the overall concept of the present invention, a detailed description is provided below with reference to the accompanying drawings and examples.

[0052] Please refer to Figures 1 to 4 As shown in the figure, this embodiment introduces the specific structure of an intelligent laser dotting device for correction. The main structure of the dotting device includes a base 1 and a main body 2. The base 1 serves as the supporting foundation for the entire instrument, and a motor 3 is fixedly installed at the center of its bottom. The output shaft of the motor 3 extends vertically upward, passes through the center hole at the top of the base 1, and is fixedly connected to the center of the bottom end of the main body 2. To ensure the stability and centering of the main body 2 during rotation, a sliding-fit annular guide rail or rolling bearing structure is provided between the top of the base 1 and the bottom of the main body 2, so that the motor 3 can drive the main body 2 to rotate back and forth along a preset path a at the top of the base 1; path a is a closed-loop annular line to meet the dotting or calibration requirements in different directions.

[0053] like Figure 2 As shown, the main body 2 has a cuboid design with an internal cavity, and its exterior serves as a mounting platform for the laser emitting devices. Laser emitting device 1 4 and laser emitting device 2 5 are fixedly mounted on the main body 2, and the two are installed perpendicular to each other, with the emitted horizontal beams being vertical beams. Specifically, the housings of laser emitting device 1 4 and laser emitting device 2 5 are precisely fixed to two adjacent sides of the main body 2 by screws or slots, so that their optical axes are perpendicular to each other in the horizontal plane, thereby projecting perpendicular vertical laser lines onto the wall surface for calibrating the verticality of the wall or for right-angle positioning. The positions of these two laser emitting devices are fixed, and they can rotate with the main body 2 as it rotates on the top of the base 1 during operation.

[0054] like Figures 3 to 6As shown, a laser emitting device 6 is rotatably connected to the main body of the main body 2. The horizontal beam emitted by the laser emitting device 6 is parallel to the ground and is perpendicular to the vertical beams emitted by the laser emitting device 4 and the laser emitting device 5. A motor 7 is fixedly installed inside the main body 2. A gear set 8 is installed between the output end of the motor 7 and the rotating shaft of the laser emitting device 6. The gear set 8 consists of a driving gear and a driven gear. The driving gear is installed on the output shaft of the motor 7, and the driven gear is fixed on the rotating shaft of the laser emitting device 6. The two mesh with each other. When the motor 7 is powered on, it rotates. Through the deceleration and torque amplification of the gear set 8, the laser emitting device 6 is driven to rotate slowly and precisely around its rotating shaft, thereby adjusting the pitch angle of the horizontal beam emitted by it.

[0055] Specifically, such as Figure 5 As shown, the horizontal beam emitted by laser emitting device 6 rotates back and forth along path b. In daily work, since the horizontal positions to be calibrated vary in height, the traditional method is to manually adjust the height of the entire instrument or use a lifting platform to adjust the horizontal beam to the required height before calibration, which is cumbersome and inefficient. This invention drives laser emitting device 6 to rotate via motor 7, which can quickly change the projection angle of the horizontal beam, thereby achieving calibration at different heights without moving or raising the instrument itself, greatly improving the convenience and adaptability of use.

[0056] like Figure 1 , Figure 7 and Figure 8 As shown, a positioning component 9 is movably connected to one side of the base 1. The positioning component 9 is electrically connected to the main body 2 via an electrical plug 11, which is used to charge the internal electrical equipment of the positioning component 9. The positioning component 9 has a cuboid design, and a level tube 10 is installed on its top and side. The posture of the positioning component 9 can be adjusted by observing the position of the bubble in the level tube 10. The movable connection between the positioning component 9 and the base 1 can be a slot type, a snap-on type, or a magnetic type, which is convenient for disassembly, assembly, and carrying. When the positioning component 9 is installed on the base 1, the electrical plug 11 automatically engages to achieve electrical connection. When the positioning component 9 needs to be used alone for measurement, it can be removed.

[0057] like Figure 9 As shown, this embodiment, based on the aforementioned mechanical structure of the intelligent correction laser dotting instrument, further introduces an intelligent correction laser dotting instrument control system; the control system mainly consists of two parts: a lower-level computer and a higher-level computer.

[0058] The lower-level computer includes attitude and motion sensors installed inside the positioning component 9, control sensors installed inside the main body 2, position sensors for detecting the relative position between the main body 2 and the positioning component 9, and corresponding communication equipment. The upper-level computer, as the control core of the system, includes an analysis unit, a control unit, and a correction unit. The analysis unit is responsible for receiving and parsing the attitude and position information uploaded by the lower-level computer; the control unit generates control commands based on the analysis results to drive motor 3 and motor 7 to perform corresponding actions; the correction unit is used to receive motion sensor data during the fine-tuning stage, calculate the follow-up adjustment amount in real time, and ensure that the laser beam ultimately points accurately to the target area.

[0059] The positioning component 9, as an independently detachable measurement reference module, has an embedded attitude sensor that monitors its placement posture in real time, accurately determining whether it is currently vertical or horizontal. In practical applications, when calibrating the horizontal or vertical alignment of a wall or windowsill, the operator can remove the positioning component 9 from the base 1 and place it against the target surface. For example, the component can be placed vertically against a wall to measure verticality, or horizontally against a windowsill to measure horizontality. At this time, the attitude sensor immediately senses the placement of the component and transmits this attitude information to the control unit inside the main body 2 via a communication device.

[0060] After receiving the attitude information, the main body 2 first activates the position sensor between itself and the positioning component 9 to obtain the spatial orientation and distance information of the positioning component 9 relative to the current location of the main body 2. This position sensor functions when the positioning component 9 is far from the main body 2; for example, the main body 2 is typically placed on the floor in the center of a room, while the positioning component 9 is carried by the operator to a corner of a windowsill and placed against the windowsill surface. The position sensor determines the specific orientation and approximate distance of the positioning component 9 in the room through wireless ranging or signal angle measurement, providing the main body 2 with preliminary coordinate references for the target location.

[0061] However, due to environmental interference or sensor accuracy limitations, single position measurements may contain deviations, causing the laser beam to fail to accurately point to the target area. To address this, the positioning component 9 is equipped with a motion sensor to detect the component's displacement trajectory during movement. When the operator observes that the laser beam is not accurately aligned with the target, they can slowly move the positioning component 9 near the target. The motion sensor collects the displacement direction and distance of the positioning component 9 in real time and uploads the movement information to the correction unit on the host computer via a communication device. The correction unit calculates the required angle change for the laser beam based on the movement information and sends the adjustment command to the control unit. The control unit then drives motor 3 and / or motor 7, causing the laser projection point to follow the movement of the positioning component 9 in real time. By observing the adhesion between the laser beam and the target surface, the operator continuously micro-moves the positioning component 9 until the laser beam is accurately aligned with the target position, at which point movement stops, completing the calibration. This human-machine collaborative iterative approximation method effectively compensates for the accuracy limitations of single measurements by the position sensor, further improving the accuracy and adaptability of calibration.

[0062] The control sensors installed inside the main body 2 are primarily used to monitor the main body's operating status and attitude. These include a tilt sensor for detecting the main body's levelness and an encoder for monitoring the rotation angles of motor 3 and motor 7. This sensor data ensures the stability and accuracy of the main body during rotation and adjustment, and provides real-time feedback to the host computer for closed-loop control, ensuring accurate adjustment of the laser beam.

[0063] The communication device connects the various modules of the lower-level machine and the upper-level machine. It is responsible for packaging and sending the data collected by the attitude sensor, position sensor, motion sensor, and control sensor to the upper-level machine. At the same time, it receives the control commands issued by the upper-level machine, parses them, and transmits them to motor 3 and motor 7. The communication method can be wired or wireless. Considering the mobile nature of the positioning component 9, wireless communication methods such as Bluetooth, WiFi, or radio frequency communication are selected to ensure flexibility and convenience during use.

[0064] After receiving the data uploaded by the lower-level computer, the analysis unit of the host computer first interprets the attitude information. If the attitude sensor shows that the positioning component 9 is in a vertical state, it means that the operator wants to calibrate a vertical plane. In this case, the analysis unit will combine the orientation information provided by the position sensor to determine that the vertical beam emitted by laser emitting device 1 4 and laser emitting device 2 5 needs to be adjusted. If the attitude sensor shows that the positioning component 9 is in a horizontal state, it means that a horizontal plane needs to be calibrated. In this case, the horizontal beam emitted by laser emitting device 3 6 should be adjusted. The analysis unit will also calculate the initial angle and direction of the laser beam deflection based on the relative position data given by the position sensor.

[0065] Based on the calculation results of the analysis unit, the control unit generates preliminary control signals. When the direction of the vertical beam needs to be adjusted, the control unit drives motor 3 to rotate. The output shaft of motor 3 drives the main body 2 to rotate on the annular guide rail of the base 1 until the vertical laser lines emitted by laser emitting devices 4 and 5 point to the preliminary position of the positioning component 9. When the height of the horizontal beam needs to be adjusted, the control unit drives motor 7 to operate. Motor 7, through the reduction and torque amplification of gear set 8, drives laser emitting device 6 to rotate around its axis, changing the pitch angle of the horizontal laser line so that it is projected onto the preliminary height position of the positioning component 9. During the preliminary adjustment process, the control unit will correct the rotation amount of motor 3 or motor 7 in real time based on the feedback signals from control sensors such as encoders to ensure the basic accuracy of positioning.

[0066] However, due to environmental interference, multipath effects, or limitations in sensor accuracy, single position measurements may contain deviations, causing the laser beam to point to a preliminary orientation but fail to precisely adhere to the target surface. To address this, the positioning component 9 is equipped with a motion sensor, typically a combination of a MEMS accelerometer and gyroscope, used to detect the positioning component 9's movement trajectory and minute displacements in space in real time. When the operator observes that the laser beam is not accurately aligned with the target, they can slowly move the positioning component 9 near the target surface, such as sliding it back and forth along a windowsill edge or moving it up and down on a wall. The motion sensor continuously collects instantaneous acceleration and angular velocity data of the positioning component 9 at a sampling frequency of tens to hundreds of times per second, and uploads this raw motion data in real time to the correction unit of the host computer via a communication device.

[0067] The correction unit is a core module specifically designed for precise tracking, integrating motion calculation algorithms. Upon receiving real-time data from the motion sensor, this unit first integrates and filters the acceleration and angular velocity data to calculate the displacement vector and direction change of the positioning component 9 relative to the previous moment. The correction unit establishes a mapping relationship between these displacement changes and the current projection angle of the laser beam, calculating in real-time the angle compensation required by motors 3 and 7 to track the movement of the tracking component. For example, when the operator moves the positioning component 9 5 millimeters to the right, the correction unit, through geometric calculation, determines that to keep the laser beam aligned with the component, the main body 2 needs to rotate to the right by a corresponding small angle, or the laser emitting device 6 needs to adjust a corresponding pitch compensation. The correction unit sends this real-time compensation to the control unit in the form of a correction command.

[0068] Upon receiving the correction command, the control unit immediately drives the corresponding motor to perform a minute angle adjustment. This process cycles at an extremely high frequency: the operator moves the component – ​​the motion sensor collects data – the correction unit calculates the compensation amount – the control unit drives the motor to follow – the laser line points to the new position in real time. The operator visually observes the adhesion between the laser line and the target surface, continuously micro-moving the positioning component 9, forming a closed-loop human-machine collaborative adjustment process. As the positioning component 9 moves, the laser projection point follows in real time until the operator moves the positioning component 9 to a position where the laser line is completely in contact with the target surface, at which point the movement stops, and the calibration is complete. The correction unit plays a core role in "dynamic calculation" and "real-time guidance" throughout the process, seamlessly connecting the operator's subjective observation with the equipment's automatic adjustment, and effectively eliminating the residual error of a single positioning through iterative approximation.

[0069] The control sensors installed inside the main body 2 are mainly used to monitor the main body's operating status and attitude, including an inclination sensor to detect the main body's levelness and encoders to monitor the rotation angles of motor 3 and motor 7. During the fine-tracking phase, the encoders also play a crucial role, feeding back the actual rotation angle of the motors to the control unit in real time. This feedback is compared with the compensation amount given by the correction unit to form a closed-loop control, ensuring that every minute adjustment is precise.

[0070] The communication device connects the various modules of the lower-level machine and the upper-level machine. It is responsible for packaging and sending the data collected by the attitude sensor, position sensor, motion sensor, and control sensor to the upper-level machine. At the same time, it receives the preliminary control commands and correction commands issued by the upper-level machine, parses them, and transmits them to motor 1 (3) and motor 2 (7). The communication method adopts wireless communication methods such as Bluetooth, WiFi, or radio frequency communication to meet the flexibility requirements of the positioning component 9 for its mobile use.

[0071] like Figure 10As shown, taking the calibration of a windowsill's levelness as an example, the complete workflow is as follows: The operator places the main body 2 on the center of the room and turns it on. Then, the operator removes the positioning component 9 and places it horizontally on the windowsill. The attitude sensor inside the positioning component 9 immediately detects that the component is in a horizontal state and sends this attitude information to the main body 2 via wireless communication. After receiving the information, the main body 2 activates the position sensor between itself and the positioning component 9 to measure the initial orientation and distance of the component relative to the main body 2. This data, along with the attitude information, is uploaded to the host computer. The host computer analysis unit determines that the horizontal beam needs adjustment and calculates the initial pitch angle that the laser emitting device 6 should rotate based on the position data. The control unit drives the motor 7 to rotate the laser emitting device 6, so that the horizontal laser line is projected near the windowsill. At this time, the operator observes the laser line and finds that it is not completely aligned with the windowsill. So, the operator slowly slides the positioning component 9 along the windowsill. The motion sensor collects the displacement trajectory of the component in real time and uploads the data to the correction unit. The correction unit calculates the compensation angle that needs to be followed, and the control unit then drives the motor 7 to make fine adjustments so that the laser line always follows the movement of the component. The operator slides the component while observing the laser line. When the laser line is completely aligned with the edge of the windowsill, the movement is stopped, and the precise calibration is completed.

[0072] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.

The attitude sensor detects the placement attitude of the positioning component (9) and sends it to the host computer through the communication device; S3. The position sensor acquires the preliminary orientation and distance information of the positioning component (9) relative to the main body (2) and sends it to the host computer. S4. The analysis unit determines the type of wire harness to be adjusted and the initial adjustment amount based on the attitude information and position information. The control unit drives motor one (3) and motor two (7) to perform the initial alignment. S5. The operator moves the handheld positioning component (9) on the target surface, and the motion sensor collects the displacement trajectory in real time and uploads it to the correction unit. S6. The correction unit calculates the following compensation amount, and the control unit drives motor one (3) and motor two (7) to make the laser beam follow the positioning component (9) in real time. S7. The operator observes the adhesion between the laser line and the target surface, and stops moving when they are perfectly aligned to complete the calibration.
