[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1-7 , the present invention is further introduced in detail.

[0034] An embodiment of the present invention provides an intelligent digital flatness and verticality measuring tool, comprising a measuring body 1, a digital display module 2 for displaying measurement data, a wireless communication module 3 for sending measurement data, a power supply module 4 for power supply, a three-axis acceleration sensor 5 is arranged in the measuring body 1, and the three-axis acceleration sensor 5 is used to measure verticality; a movable slide groove 11 is opened on the side wall of the measuring body 1, and a movable laser displacement sensor 6 is arranged in the movable slide groove 11, and the laser displacement sensor 6 is used to measure flatness.

[0035] Specifically, the measuring body 1 is overall in the shape of a long strip and a ruler, and a horizontal tube is provided on the measuring body 1 (the horizontal tube is usually a translucent or transparent glass tube filled with liquid and a bubble; the bubble moves in the liquid to indicate the horizontal state). When the flatness or verticality of the wall needs to be measured, the staff will place the measuring body 1 against the wall. At this time, the measuring body 1 is equivalent to a ruler against the wall. The staff uses a feeler gauge to insert into the gap between the measuring body 1 and the wall to complete the verticality measurement, and observes the bubble in the horizontal tube on the measuring body 1.

[0036] Obviously, the accuracy of existing bubble levels is low, usually at 0.5mm / m. For projects that require high precision, the data measured by the bubble level is not sufficient to support construction personnel in their grasp of project quality. In addition, the movement of the bubbles in the bubble level is not sensitive enough, and it is difficult to detect slight tilts. When slight tilts occur, users are required to have good visual judgment skills, resulting in data that is too subjective. In addition, when measuring data, it is necessary to wait for the bubbles to stabilize before readings can be taken, resulting in low detection efficiency, which affects construction efficiency.

[0037] In order to solve the above problems, a digital display module 2 for displaying measurement data, a wireless communication module 3 for sending measurement data, and a power supply module 4 for power supply are installed on the measuring body 1; a three-axis acceleration sensor 5 is arranged in the measuring body 1, and the three-axis acceleration sensor 5 is used to measure verticality; a movable slide groove 11 is opened on the side wall of the measuring body 1, and a movable laser displacement sensor 6 is arranged in the movable slide groove 11, and the laser displacement sensor 6 is used to measure flatness.

[0038] Specifically, the flatness is scanned by the laser displacement sensor 6 in a straight line to measure the fluctuation of the entire target area. It can not only measure the flatness deviation, but also record the fluctuation size of each point at the corresponding position to achieve more refined flatness measurement; the laser displacement sensor 6 uses triangulation, which is also called optical triangulation ranging method, and is a commonly used non-contact measurement technology; it is based on the principle of triangulation and calculates the angle change of the laser pulse after it is reflected on the target object. This method has high accuracy and high speed and can adapt to various environments and conditions; the light beam emitted by the laser is focused and forms a bright spot on the target object. When this bright spot moves on the surface of the object, its position on the photosensitive element will also change accordingly. , this change can be detected and recorded by a photosensitive element (such as CCD or CMOS). Specifically, the light emitted by the laser source shines on the target object, and then the light is reflected back and passes through a lens. This lens is designed to focus all the light from the target object on the photosensitive element. When we change the distance between the target object and the laser source, since the focal length of the lens (that is, the distance from the focus point of the light beam to the photosensitive element) remains unchanged, the incident angle of the reflected light will change, which will cause the position where the reflected light is focused on the photosensitive element to change. By measuring this position change, the distance to the target object can be calculated. The key here is to accurately measure the position of the reflected light on the photosensitive element. In order to increase the accuracy of the measurement, sub-pixel level calculation is often used To determine the center position of the light spot, this calculation method uses the intensity distribution characteristics of the light spot, that is, the brightness of the center of the light spot is the highest and gradually decreases outward. By fitting this brightness distribution model, the center position of the light spot can be accurately calculated, thereby improving the accuracy of the measurement; the three-axis acceleration sensor 5 is a sensor that detects the motion state of an object by measuring the acceleration of the object in the directions of three coordinate axes; the three-axis acceleration sensor 5 is usually a tiny chip made of micro-electromechanical system (MEMS) technology. The three-axis acceleration sensor 5 contains a tiny oscillating structure that can generate a voltage difference in response to an external force. The three-axis acceleration sensor 5 uses the basic principle of Newton's law: the acceleration of an object is proportional to the force and inversely proportional to the mass; the three-axis acceleration sensor The tiny oscillating structure inside the sensor 5 can sense the motion state of the object, wherein the charge output is related to the motion state. Therefore, when the object is subjected to external force, the oscillating structure in the three-axis acceleration sensor 5 will produce a tiny offset, thereby causing the output signal to change. The three-axis acceleration sensor 5 has the characteristics of easy assembly, extremely small size and low power consumption. By accurately measuring the acceleration in three directions, they can provide very accurate position and motion state information; wherein, the digital display module 2 includes a display screen, which is communicatively connected with the three-axis acceleration sensor 5 and the laser displacement sensor 6. When the laser displacement sensor 6 detects the flatness and the three-axis acceleration sensor 5 detects the verticality, the detected flatness and verticality values ​​are displayed on the display screen;The wireless communication module 3 includes a communication connection with the mobile phone APP through Bluetooth. When the three-axis acceleration sensor 5 and the laser displacement sensor 6 measure the flatness and verticality respectively, the wireless communication module 3 transmits the measured data to the mobile phone APP to save the data, which is convenient for subsequent data access and avoids data recording errors or data loss. Among them, the power module 4 is powered by a lithium battery with a protection board, and the power module 4 provides power for the wireless communication module 3 and the digital display module 2. When it is necessary to measure the verticality and horizontality, the construction personnel put the measuring body 1 against the wall, and then the laser displacement sensor 6 slides along the moving slide 11 of the measuring body 1 to measure the flatness of the front. At the same time, the three-axis acceleration sensor 5 starts to work and measures the verticality of the front. When the measurement of flatness and verticality is completed, the data of the flatness and verticality of the wall are displayed on the digital display module 2, and the wireless communication module 3 sends the measured flatness and verticality data to the mobile phone APP to save the measured data, thereby realizing the measurement and processing of the verticality and flatness of the wall. ;

[0039] Preferably, a movable guide rail 12 and a driving component 13 are provided in the movable slide groove 11, and the driving component 13 drives the laser displacement sensor 6 to slide along the movable guide rail 12; the driving component 13 is installed on the movable guide rail 12, and the driving component 13 includes a stepping motor 131, a screw rod 132 and a movable slide 133, the output end of the stepping motor 131 is connected to the screw rod 132, and the stepping motor 131 is used to drive the screw rod 132 to rotate, and a movable slide 133 is provided on the screw rod 132, and the movable slide 133 slides along the movable guide rail 12 based on the rotation of the screw rod 132, and the laser displacement sensor 6 is fixedly installed on the movable slide 133.

[0040] Specifically, in the initial state, the laser displacement sensor 6 is located at the end of the movable slide groove 11. When the flatness measurement is required, the construction personnel place the measuring body 1 against the wall, and the movable slide groove 11 on the measuring body 1 is facing the wall. Then the stepper motor 131 starts to work, and the stepper motor 131 rotates with the screw rod 132. As the screw rod 132 rotates, the movable slide 133 slides along the movable guide rail 12, and the movable guide rail 12 moves synchronously with the laser displacement sensor 6. As the laser displacement sensor 6 moves, the detection and processing of the flatness of the wall is completed. After the detection is completed, the stepper motor 131 rotates in the opposite direction, driving the screw rod 132 to rotate in the same direction, so that the movable slide 133 moves with the laser displacement sensor 6 along the movable guide rail 12 to the initial position, waiting for the next flatness detection.

[0041] Obviously, since the equipment is usually used at construction sites, which contain a lot of dust and dirt, it is easy for dust and dirt to adhere to the laser displacement sensor 6, causing obstruction or even blocking of the laser beam, which can easily cause the sensor to be unable to receive effective reflection signals, affecting the accuracy of the measurement data.

[0042] In order to solve the above problems, a protective component 7 is further provided in the movable slide groove 11, and the protective component 7 is used to protect the lens of the laser displacement sensor 6 to prevent dust and dirt from adhering to the lens of the laser displacement sensor 6, wherein the protective component 7 includes a shielding portion 71 and a triggering portion 72, and the shielding portion 71 is used to close the movable slide groove 11, wherein the shielding portion 71 includes two shielding plates 711, and the two shielding plates 711 are rotatably mounted on the measuring body 1 by a rotating shaft 712, and the rotating shaft 712 is connected to the measuring body 1 by a torsion spring (the torsion spring is not shown in the figure), when the torsion spring is not subjected to force, the two shielding plates 711 are parallel and aligned with each other to close the movable slide groove 11, and when the measuring body 1 is against the wall, the triggering portion 72 is triggered based on the extrusion of the wall, and the triggering portion 72 drives the rotating shaft 712 to rotate, and the two shielding plates 711 rotate The movable slide groove 11 is opened manually, wherein the trigger part 72 includes a plurality of trigger push rods 721, two trigger push rods 721 form a group, one group of trigger push rods 721 corresponds to a baffle plate 711, and the two trigger push rods 721 in a group are respectively arranged on both sides of the baffle plate 711, and the end of the trigger push rod 721 close to the wall is wrapped with a rubber sleeve 722, and the other end of the trigger push rod 721 is installed with a driving rack 723, and the driving rack 723 is slidably installed on the measuring body 1, and one end of the driving rack 723 extends into the movable slide groove 11, and the outer side of the driving rack 723 located in the movable slide groove 11 is provided with a meshing rotating gear 724, and the rotating gear 724 is fixedly installed on the rotating shaft 712, and the end of the driving rack 723 away from the trigger push rod 721 is connected to the measuring body 1 through a reset spring 725.

[0043] Specifically, in the initial state, the torsion spring is in a stress-free state. At this time, the two shielding plates 711 are parallel and aligned with each other. The two shielding plates 711 shield the movable slide 11, preventing dust in the environment from entering the movable slide 11, causing the lens of the laser displacement sensor 6 to be blocked, affecting the accuracy of the measurement data of the laser displacement sensor 6. When measurement is required, the construction personnel press the measuring body 1 on the wall, and the trigger push rod 721 is moved toward the inside of the measuring body 1 by the reaction force of the wall. When the trigger push rod 721 moves, the return spring 725 contracts to accumulate elastic potential energy, and as the trigger push rod 721 moves synchronously with the driving rack 723, the driving rack 723 meshes with the rotating gear 724, and the rotating gear 724 rotates under the action of the driving rack 723. The rotating gear 724 rotates synchronously with the rotating shaft 712, and the rotating shaft 712 rotates with the shielding plate 711 toward the inside of the movable slide 11, and the movable slide 11 opens. The stepper motor 131 starts to work, and the stepper motor 131 rotates with the lead screw 132. As the lead screw 132 rotates, the movable slide 133 slides along the movable guide rail 12, and the movable guide rail 12 moves synchronously with the laser displacement sensor 6. As the laser displacement sensor 6 moves, the detection and processing of the wall flatness is completed; after the wall flatness detection is completed, the construction personnel take the measuring body 1 away from the wall, and the reset spring 725 releases the accumulated elastic potential energy. The reset spring 725 pushes the driving rack 723 to move with the trigger push rod 721 toward the wall. As the driving rack 723 engages with the rotating gear 724, the rotating gear 724 rotates in the opposite direction with the rotating shaft 712, and the two shielding plates 711 are restored to a state of being parallel and abutting against each other. At this time, the movable slide 11 is closed again to protect the laser displacement sensor 6 in the movable slide 11 to prevent dust from falling on the laser displacement sensor 6 and affecting the accuracy of the laser displacement sensor 6 during measurement.

[0044] Obviously, when measuring the flatness, the baffle 711 needs to be opened. At this time, the space inside the movable chute 11 is connected to the outside world, and the dust in the air can easily enter the interior of the movable chute 11, and then adhere to the laser displacement sensor 6, affecting the accuracy of the laser displacement sensor 6 when measuring data.

[0045] Preferably, in this embodiment, the movable guide rail 12 includes a movable section 121, a connecting section 122 and a fixed section 123, wherein one end of the connecting section 122 is rotatably connected to the movable section 121, and the other end of the connecting section 122 is rotatably connected to the fixed section 123, the movable section 121 is slidably installed in the movable slide groove 11, and a connecting rod 124 is provided on the driving rack 723 near the movable section 121, and the other end of the connecting rod 124 is connected to the movable section 121.

[0046] Specifically, the connecting section 122 is a retractable structure. In the initial state, the movable section 121 and the fixed section 123 are spaced apart from each other. When the flatness test is required, the construction personnel press the measuring body 1 on the wall, and the trigger push rod 721 is moved toward the inside of the measuring body 1 by the reaction force of the wall. When the trigger push rod 721 moves, the reset spring 725 contracts to accumulate elastic potential energy, and the trigger push rod 721 moves synchronously with the driving rack 723. As the driving rack 723 moves, the connecting rod 124 on the driving rack 723 drives the movable section 121. The gear 724 is driven to move synchronously, and the rack 723 is driven to mesh with the rotating gear 724. The rotating gear 724 rotates under the action of the rack 723, and the rotating gear 724 rotates synchronously with the shaft 712. The shaft 712 rotates with the shielding plate 711 toward the inside of the moving slide 11, and the moving slide 11 is opened. At this time, the moving section 121, the connecting section 122 and the fixed section 123 are also aligned with each other to form a straight line. After that, the stepper motor 131 starts to work, and the stepper motor 131 rotates with the lead screw 132. As the lead screw 132 rotates, the moving slide 1 33 slides along the moving guide rail 12, and the moving guide rail 12 moves synchronously with the laser displacement sensor 6. With the movement of the laser displacement sensor 6, the detection of the flatness of the wall is completed; after the wall flatness detection is completed, the stepper motor 131 rotates in the opposite direction. When the laser displacement sensor 6 returns to the moving section 121, the construction personnel take the measuring body 1 away from the wall, and the reset spring 725 releases the accumulated elastic potential energy. The reset spring 725 pushes the driving rack 723 to move with the trigger push rod 721 toward the wall. With the driving rack 723 and the trigger push rod 721, the construction personnel take the measuring body 1 away from the wall. The rotating gear 724 is engaged, and the rotating gear 724 rotates in the opposite direction with the rotating shaft 712, and the two shielding plates 711 are restored to a state of being parallel and abutting against each other. At the same time, with the movement of the driving rack 723, under the action of the connecting rod 124, the moving section 121 carries the laser displacement sensor 6 and the driving assembly 13 as a whole and moves in the opposite direction toward the fixed section 123 away from the moving guide rail 12, and the lens of the laser displacement sensor 6 abuts against the inner wall of the moving slide groove 11 to prevent dirt that enters the moving slide groove 11 from floating onto the laser displacement sensor 6 and affecting the accuracy of subsequent measurement data.

[0047] Preferably, in order to prevent the inner wall of the movable slide groove 11 from scratching the lens of the laser displacement sensor 6, the area where the movable slide groove 11 contacts the lens of the laser displacement sensor 6 should be provided with a flexible layer such as a sponge pad 14 to protect the lens; obviously, in order to increase the measuring length of the device, two measuring bodies 1 can be provided, the ends of the two measuring bodies 1 are rotatably connected, and a buckle 8 is provided on one of the measuring bodies 1. When the two measuring bodies 1 are unfolded and present a parallel state, the two measuring bodies 1 are fixed by the buckle 8 to increase the measuring length of the device.

[0048] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
