[0036] The present invention will be further described below with reference to the embodiments.

[0037] See also Figure 1-8 The present invention provides a floor flatness detection device with intelligent visual recognition and feedback, comprising a mounting bracket 1, wherein the mounting bracket 1 comprises a longitudinal strap 11 and a transverse guide rail 12, two transverse guide rails 12 are installed between the two longitudinal straps 11, and threaded cylinders 13 are fixedly embedded at both ends of the longitudinal straps 11, screw rods 14 are threadedly connected in the threaded cylinders 13, and the bottom ends of the screw rods 14 are fixedly connected to support legs 15;

[0038] Specifically, the screw rod 14 is threadedly connected to the threaded barrel 13 and is used to adjust the height of the mounting bracket 1. By rotating the screw rod 14, the longitudinal strap 11 can be raised or lowered, and by adjusting the height of each of the four legs 15, the overall levelness of the mounting bracket 1 can be adjusted. This is crucial to ensuring that the flatness detection box 4 remains level during the detection process, as only when it is level can the detection results be accurate and reliable.

[0039] Furthermore, a groove 121 is provided on the upper side of the transverse guide rail 12, and upper notches 122 having the same width as the longitudinal strap 11 are provided on the lower sides of both ends of the transverse guide rail 12, and lower notches 111 having the same width as the transverse guide rail 12 are provided on the upper side of the longitudinal strap 11 corresponding to the upper notches 122;

[0040] Specifically, the design of the groove 121 enables the first guide wheel 22 to remain in the predetermined track during rolling, reducing shaking and errors during lateral movement. The upper groove 122 is used to cooperate with the lower groove 111 on the longitudinal strap 11 to achieve a precise matching connection between the transverse guide rail 12 and the longitudinal strap 11. Since the mounting bracket 1 is detachable, this greatly facilitates equipment transportation. It is worth noting that multiple mounting brackets 1 can be built in parallel so that the grooves 121 of adjacent mounting brackets 1 are aligned with each other, which can extend the detection length to achieve a wider range of floor flatness detection.

[0041] Furthermore, a first carrying component 2 capable of laterally displacement is mounted on the carrying bracket 1. The first carrying component 2 includes two sliding frames 21 respectively located above the transverse guide rail 12. Two first guide wheels 22 are rotatably connected between the inner walls of both sides of the sliding frame 21. The thickness of the first guide wheel 22 is consistent with the width of the groove 121. Two guide rods 23 are fixedly connected between the two sliding frames 21. A first motor 24 is fixedly connected to one side of the middle of one of the sliding frames 21. The output end of the first motor 24 extends into the sliding frame 21 and is fixedly connected to a walking wheel 25. The radius of the walking wheel 25 is consistent with the radius of the first guide wheel 22.

[0042] Specifically, when lateral movement is required, the first motor 24 is started, and its output end drives the walking wheel 25 to rotate, and the walking wheel 25 rolls along the transverse guide rail 12. Since the walking wheel 25 is tightly fitted with the groove 121 of the transverse guide rail 12, the rolling process is smooth and smooth. The rolling of the walking wheel 25 drives the entire sliding frame 21 to move along the transverse guide rail 12. Since the two sliding frames 21 are connected by the guide rod 23, the first carrying component 2 can move in the transverse direction, thereby switching the detection area.

[0043] Furthermore, a second longitudinally displaceable carrying assembly 3 is mounted on the carrying bracket 1. The second carrying assembly 3 includes a transmission box 31 and two guide frames 32 respectively fixed on both sides of the transmission box 31. At least two second guide wheels 33 are rotatably connected between the inner walls of the two sides of the guide frame 32. A recessed groove 34 that is compatible with the structure of the guide rod 23 is provided on the outer peripheral wall of the second guide wheel 33. A second motor 35 is fixedly connected to the inner wall of the transmission box 31. The output end of the second motor 35 is fixedly connected to a driving bevel gear 36. The driving bevel gear 36 is meshed with a driven bevel gear 37. The driven bevel gear 37 is fixedly sleeved on the outer side of a transmission rod 38. Both ends of the transmission rod 38 pass through the transmission box 31 and are fixed to adjacent second guide wheels 33.

[0044] Specifically, when longitudinal movement is required, the second motor 35 is started, and its output end drives the active bevel gear 36 to rotate. The active bevel gear 36 drives the driven bevel gear 37 to rotate through the meshing relationship, thereby transmitting power to the transmission rod 38. The rotation of the transmission rod 38 drives the second guide wheel 33 to rotate. Since the second guide wheel 33 is closely matched with the guide rod 23, the recessed groove 34 can prevent the second guide wheel 33 from derailing. The rotation of the second guide wheel 33 will move along the direction of the guide rod 23. The movement of the second guide wheel 33 drives the entire transmission box 31 and the flatness detection box 4 to move in the longitudinal direction, switching the detection area.

[0045] Furthermore, a flatness detection box 4, a PLC controller 5 and a power supply device 6 are installed on the second carrying component 3. The flatness detection box 4 is fixed to the bottom wall of the transmission box 31, the power supply device 6 is fixed to the top wall of the transmission box 31, and the PLC controller 5 is installed in the transmission box 31.

[0046] Specifically, the flatness detection box 4 moves with the transmission box 31, and the PLC controller 5 is responsible for receiving data from the optical signal acquisition board 43, integrating the light and dark images of the local detection area, and generating a three-dimensional image of the entire floor. In addition, the PLC controller 5 also controls the movement of the first motor 24 and the second motor 35 to realize the lateral and longitudinal movement of the flatness detection box 4, thereby completing the detection of large-area floors. It is worth noting that the PLC controller 5 is also connected to a control terminal in a wired or wireless form, such as a computer, which can facilitate staff to control the equipment in real time and view the flatness detection results. The power supply equipment 6 can be a battery, a lithium battery or a lead-acid battery, which is intended to provide power for the operation of the flatness detection equipment.

[0047] Furthermore, the flatness detection box 4 includes a box body 41 with an open bottom, an optical signal transmitting board 42 is fixedly embedded at one end of the box body 41, and light emitting diodes 421 that can emit visible light or invisible light are densely arranged on the back of the optical signal transmitting board 42, and a light doubling plate 422 is fixedly embedded on the front of the optical signal transmitting board 42, so that the light emitted by the light emitting diodes 421 can pass through the light doubling plate 422 to illuminate the detection area of ​​the floor;

[0048] Specifically, the function of the light homogenizer 422 is to homogenize the light emitted by the light-emitting diode 421, making the light more parallel and evenly distributed. The uniform light can ensure that the light intensity received by each point in the detection area is consistent, thereby improving the stability of the reflected signal and the detection accuracy. It can also reduce stray light during the propagation process and avoid the generation of interference signals. It is worth noting that visible light is also used as the detection light source at night, and invisible light (such as infrared light or ultraviolet light) is used as the detection light source during the day, which can effectively reduce the interference of external visible light. Because infrared light and ultraviolet light are relatively less in the natural environment, the purity of the detection signal can be improved.

[0049] Furthermore, an optical signal acquisition board 43 is fixedly embedded at the other end of the box body 41 for acquiring the reflected light after the light emitted by the optical signal transmitting board 42 hits the floor. A photosensitive unit 431 is provided on the side of the optical signal acquisition board 43 facing the reflected light. The photosensitive unit 431 is a photodiode or a charge-coupled device. A black light-absorbing board 44 is fixedly embedded between the optical signal transmitting board 42 and the optical signal acquisition board 43 and on the inner wall of the box body 41.

[0050] Specifically, both the photodiode and the charge-coupled device can sense the intensity of light. The main function of the black light-absorbing plate 44 is to absorb stray light inside the box body 41 to prevent such light from interfering with the normal operation of the photosensitive unit 431. Stray light may cause errors in the detection signal and affect the accuracy of flatness detection.

[0051] Furthermore, the horizontal angle of the optical signal transmitting board 42 is 30-45 degrees, and the optical signal collecting board 43 is located on the transmission path of the reflected light and is arranged perpendicular to the reflected light;

[0052] Specifically, an angle of 30° to 45° can ensure that the emitted light can cover a sufficiently wide detection area while avoiding detection blind spots caused by angles that are too small or too large. The optical signal acquisition board 43 is designed to be perpendicular to the transmission path of the reflected light, which means that the photosensitive unit 431 can receive the reflected light at the optimal angle, thereby maximizing the capture of the reflected signal.

[0053] Working principle: When using the intelligent visual recognition and feedback floor flatness detection equipment, the following steps are included:

[0054] Step 1: After the floor flatness control device is set up, rotate the different legs 15 so that the screw rod 14 extends out of the threaded barrel 13 until the flatness detection box 4 is adjusted to a horizontal state;

[0055] Step 2: The light emitting diode 421 emits an initial light beam, which is converted into mutually parallel detection light beams by the light homogenizer 422. The detection light beams illuminate the detection area of ​​the floor to form reflected light beams. The photosensitive unit 431 on the optical signal acquisition board 43 collects the intensity information of the reflected light beams in real time to obtain a light and dark image of the first local detection area.

[0056] Step 3: The first motor 24 drives the traveling wheel 25 to rotate, and the traveling wheel 25 rolls along the transverse guide rail 12, driving the flatness detection box 4 to change its transverse position. The second motor 35 drives the active bevel gear 36 to rotate, and the active bevel gear 36 drives the driven bevel gear 37 to rotate. The driven bevel gear 37 drives the guide rod 23 to rotate, and the guide rod 23 drives the two second guide wheels 33 to rotate, driving the flatness detection box 4 to change its longitudinal position, and can switch to the second local detection area to obtain the light and dark images of the second local detection area.

[0057] Step 4: By analogy, the PLC controller 5 can integrate the light and dark images of the local detection area into the light and dark images of the entire floor, and generate a three-dimensional image of the floor according to the light signal strength information of different areas of the light and dark images of the entire floor, wherein the highlight area in the light and dark image is a raised part and the stronger the light in the highlight area, the higher the height of the sunken part; the low-light area in the light and dark image is a sunken part and the darker the light in the low-light area, the lower the height of the sunken part. It is worth noting that after establishing the corresponding relationship between the regional light intensity and the height, the three-dimensional image of the floor can be generated according to the light signal strength information of different areas of the light and dark image.

A detection method for a floor flatness detection device with intelligent visual recognition and feedback according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: After the floor flatness control device is built, the different legs (15) are rotated to extend the screw rod (14) out of the threaded barrel (13) until the flatness detection box (4) is adjusted to a horizontal state; Step 2: The light emitting diode (421) emits an initial light, which is converted into mutually parallel detection light by the light homogenizing plate (422). The detection light irradiates the detection area of ​​the floor to form a reflected light, and the photosensitive unit (431) on the optical signal acquisition board (43) collects the intensity information of the reflected light in real time to obtain a light and dark image of the first local detection area; Step 3: The first motor (24) drives the running wheel (25) to rotate, and the running wheel (25) rolls along the transverse guide rail (12), driving the flatness detection box (4) to change its transverse position, the second motor (35) drives the active bevel gear (36) to rotate, the active bevel gear (36) drives the driven bevel gear (37) to rotate, the driven bevel gear (37) drives the guide rod (23) to rotate, the guide rod (23) drives the two second guide wheels (33) to rotate, driving the flatness detection box (4) to change its longitudinal position, and switching to the second local detection area to obtain the light and dark images of the second local detection area; Step 4: By analogy, the PLC controller (5) integrates the light and dark images of the local detection area into a light and dark image of the entire floor, and generates a three-dimensional image of the floor based on the light signal strength information of different areas of the light and dark image of the entire floor; Among them, the highlight area in the light and dark image is the raised part, and the stronger the light in the highlight area, the higher the height of the sunken part; the low light area in the light and dark image is the sunken part, and the darker the light in the low light area, the lower the height of the sunken part.
