Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping equipment, and in particular to a building indoor surveying and mapping device. Background Art

[0002] Interior design is to create an indoor environment that is functional, comfortable and beautiful, and meets people's material and spiritual needs based on the nature of the building's use, the environment it is in and the corresponding standards, using material and technical means and architectural design principles. Before doing interior design, accurate surveying and mapping is required. Surveying and mapping is to select existing feature points and boundaries on the ground, and obtain graphics and position information reflecting the current ground through measurement. Indoor surveying and mapping can intuitively show the structural shape of the room. Therefore, choosing a surveying and mapping device with higher accuracy can more accurately measure various indoor data.

[0003] At present, for walls with high flatness, existing surveying and mapping devices usually measure various dimensions of the room by combining a tape measure with an infrared rangefinder. Existing surveying and mapping devices can accurately measure basic data of the wall, such as thickness, height, etc. However, indoor walls are not necessarily flat, and the flatness of the same indoor wall is also different. The quality of flatness will have a great impact on the decorative effect, and even directly affect the effect of home decoration. For example, wallpapers are often designed with patterns and patterns, and the flatness of the wall is required to be high when paving. Otherwise, the wallpaper will be visually deformed. When the flatness of the wall is not obvious, the measurement personnel will not be able to see it with the naked eye and will directly measure it, which will affect the effect of wallpaper posting. Therefore, there is a need for a building indoor surveying and mapping device that can measure uneven walls. Summary of the invention

[0043] Example 1

[0044] The embodiment of the present invention provides a building indoor surveying and mapping device such as Figure 1As shown, it includes: a first support block 1, a second support block 2, a distance measuring structure 3, and a leveling structure 4. A first support rod 11 is horizontally arranged on one side of the first support block 1; a second support rod 21 is horizontally arranged on one side of the second support block 2, and the second support rod 21 is slidably connected to the first support rod 11. The first support rod 11 and the second support rod 21 can slide relative to each other to change the length of overlap between the first support rod 11 and the second support rod 21, thereby adjusting the distance between the first support block 1 and the second support block 2, and the bottom surfaces of the first support block 1 and the second support block 2 are flush, which is used as a reference when judging the flatness of the wall surface; the distance measuring structure 3 is used to measure the distance between the first support block 1 and the second support block 2. The distance between the first support block 1 and the second support block 2 is measured to obtain data such as the height and thickness of the wall; the leveling structure 4 includes a pressure sensor 41 and a moving component. The bottom surface of the second support block 2 is provided with a mounting groove 22, and the mounting groove 22 runs through the bottom surface of the second support block 2. The pressure sensor 41 is clamped in the mounting groove 22, and the moving component is arranged in the mounting groove 22. The moving component has an output end, and the output end of the moving component is connected to the pressure sensor 41. The moving component is used to adjust the position of the pressure sensor 41. Before use, the bottom surface of the pressure sensor 41 is aligned with the bottom of the mounting groove 22 (at Figure 1The middle part refers to the bottom surface of the second support block 2) is flush with the bottom surface of the pressure sensor 41, that is, the bottom surface of the pressure sensor 41 is flush with the bottom surfaces of the first support block 1 and the second support block 2. When the device measures the height of the wall, first the entire device is erected so that the first support block 1 stands on the ground, and the second support block 2 is located above the first support block 1, so that the second support block 2 contacts the top surface of the wall. At this time, the bottom surface of the first support block 1 (the bottom surface of the first support block 1 when the device is turned sideways) is close to the wall. If the pressure sensor 41 on the bottom surface of the second support block 2 (the bottom surface of the second support block 2 when the device is turned sideways) receives a pressure change signal, it means that the wall is relatively flat, and the data directly measured by the distance measurement structure 3 is the wall height; if the pressure sensor 41 does not receive a pressure change signal, it means that the wall is uneven, and the position of the pressure sensor 41 is adjusted by the moving component until the pressure sensor 41 contacts the wall and receives a pressure change signal and sends the signal to the corresponding controller. At this time, the actual height of the wall is calculated by the data measured by the distance measurement structure 3 and the data of the movement of the pressure sensor 41. The same is true when measuring the thickness of the wall, except that the entire device is placed horizontally during measurement, and the bottom surface of the first support block 1 is also placed close to the wall, and the pressure change signal of the pressure sensor 41 is detected to determine the flatness of the wall and measure the thickness of the wall. The device is provided with a leveling structure 4 to determine the flatness of the wall. When the wall is flat, the height or thickness of the wall can be directly measured through the distance measuring structure 3. When the wall is uneven, the pressure sensor 41 is first brought into contact with the wall through the leveling structure 4, and the actual height or thickness of the wall can be calculated through the distance measured by the distance measuring structure 3 and the moving component. The device can avoid the situation where the measurement accuracy is low due to the uneven wall.

[0045] This embodiment provides a specific method of moving a component, further, such as Figure 2As shown, the moving assembly includes: a driving member 42, a fixed shaft 43, a rotating drum 44, and a controller. The driving member 42 is arranged at one end of the mounting groove 22, and the driving member 42 has an output end; one end of the fixed shaft 43 is connected to the output end of the driving member 42, and the driving member 42 is used to drive the fixed shaft 43 to rotate. The driving member 42 can be a motor or a steering gear or other rotating drive structure; the rotating drum 44 is arranged at the other end of the fixed shaft 43, and the rotating drum 44 is provided with a threaded section in the circumference, the cross section of the mounting groove 22 is circular, and the inner wall of the mounting groove 22 is provided with an internal thread, the rotating drum 44 is clamped in the mounting groove 22 in the circumference and is threadedly connected with the mounting groove 22, and the pressure sensor 41 is arranged at one end of the rotating drum 44 away from the fixed shaft 43, and before measurement, the side of the pressure sensor 41 away from the rotating drum 44 is flush with the bottom surface of the first support block 1 and the second support block 2; the controller is electrically connected to the driving member 42 and the pressure sensor 41, and after the pressure sensor 41 receives the pressure change signal, the controller controls the driving member 42 to stop working. When the wall is uneven, the moving component needs to adjust the position of the pressure sensor 41 to contact the wall. The working principle of the moving component is: the driving member 42 drives the fixed shaft 43 to rotate, thereby driving the rotating drum 44 to rotate. Because the rotating drum 44 is threadedly connected with the mounting groove 22, the rotating drum 44 can also move relative to the mounting groove 22 while rotating (the rotating drum 44 moves outside the mounting groove 22), thereby driving the pressure sensor 41 to move and adjust the position of the pressure sensor 41 until the pressure sensor 41 contacts the wall and receives a pressure change signal, and sends the signal to the controller. The controller controls the driving member 42 to stop working, and calculates the actual height and thickness of the wall through the data measured by the ranging structure 3 and the data of the movement of the rotating drum 44.

[0046] This embodiment provides a specific structure of a distance measurement structure 3. Further, the distance measurement structure 3 includes: a laser emitter 31 and a laser receiver 32. The laser emitter 31 is arranged on the first support block 1, and the laser emitter 31 is flush with the side of the first support block 1 away from the first support rod 11, because the distance between the first support block 1 and the side away from the second support block 2 is the data of the actual wall surface, the laser emitter 31 is electrically connected to the controller, and the laser emitter 31 can emit infrared laser; the laser receiver 32 is arranged on the second support block 2, and the laser receiver 32 is flush with the side of the second support block 2 away from the second support rod 21, the positions of the laser emitter 31 and the laser receiver 32 are opposite, the laser receiver 32 is electrically connected to the controller, and the laser receiver 32 is used to receive the laser emitted by the laser emitter 31. The working principle of the distance measurement structure 3: the controller laser emitter 31 emits infrared laser, the laser receiver 32 receives the laser emitted by the laser emitter 31 and sends it to the controller, and the controller receives and calculates the measured value.

[0047] Furthermore, the first support block 1 and the second support block 2 are rectangular parallelepipeds, counterweight blocks are arranged inside the first support block 1 and the second support block 2, and the mass of the first support block 1 is greater than the mass of the second support block 2. When measuring the height of the wall, the entire device needs to be erected with the first support block 1 in contact with the ground, with the first support block 1 as support, and the mass of the first support block 1 is greater than the mass of the second support block 2, which is more stable to use. At the same time, when judging the flatness, there will be no deviation due to the weight of the second support block 2, avoiding measurement errors.

[0048] Example 2

[0049] As a further improvement on Example 1, when measuring the height and thickness of the wall, it is necessary to adjust the distance between the first support block 1 and the second support block 2, that is, the relative overlap length of the first support rod 11 and the second support rod 21, such as Figure 3 As shown, further, the sliding connection structure between the first support rod 11 and the second support rod 21 includes: the first rotating shaft 12 is arranged at one end of the first support rod 11 away from the first support block 1, the cross-section of the second support rod 21 is U-shaped, and the opposite sides of the second support rod 21 are respectively provided with sliding grooves 23 (that is, a pair of opposite inner side walls of the U-shaped cross-section), the sliding grooves 23 are opened along the length direction of the second support rod 21, and the two ends of the first rotating shaft 12 are respectively clamped in the two sliding grooves 23, and the first rotating shaft 12 is slidably connected with the two sliding grooves 23. The first rotating shaft 12 can slide in the two sliding grooves 23, and synchronously drive the first support rod 11 to slide in the two sliding grooves 23. During measurement, it is necessary to adjust the distance between the first support block 1 and the second support block 2 according to the height of different walls. During adjustment, the first rotating shaft 12 is made to slide in the two slide grooves 23, which can drive the first support rod 11 to slide in the two slide grooves 23, and adjust the change in the overlapping length between the first support rod 11 and the second support rod 21, thereby realizing the adjustment of the distance between the first support block 1 and the second support block 2.

[0050] In the above scheme, in order to control the first rotating shaft 12 to slide in the two sliding grooves 23 and then limit the position, as shown in FIG. Figure 3As shown, further, it also includes: a gear 13, a rack 24, and a drive assembly. The gear 13 is mounted on the first rotating shaft 12, and the gear 13 is located at one end of the first rotating shaft 12, and the gear 13 is located in one of the slide grooves 23; the rack 24 is arranged on one side of the slide groove 23 along the length direction of the slide groove 23, and the rack 24 is meshed with the gear 13; the drive assembly has an output end, and the output end of the drive assembly is connected to the first rotating shaft 12. The drive assembly is used to drive the first rotating shaft 12 to rotate, and the first rotating shaft 12 is rotatably connected to the first support rod 11, which will not affect the rotational movement of the first rotating shaft 12, and the drive assembly is electrically connected to the controller. When in use, the first rotating shaft 12 is driven to rotate by the driving component, and the gear 13 is driven to rotate synchronously, thereby moving on the rack 24, driving the first rotating shaft 12 to move in the slide groove 23, so as to adjust the overlapping length between the first support rod 11 and the second support rod 21. At the same time, after adjusting the distance between the first support block 1 and the second support block 2, the first rotating shaft 12 can be limited by controlling the driving component to stop working.

[0051] This embodiment provides a specific structure of a driving component, further, as Figure 4 As shown, the driving assembly includes: a driving motor 14, a second rotating shaft 15, a first bevel gear 16, and a second bevel gear 17. The driving motor 14 is arranged at one end of the first support rod 11 away from the first support block 1, and the base of the driving motor 14 is arranged on the first support rod 11. The driving motor 14 does not drive the first support rod 11 to rotate when it is working; the second rotating shaft 15 is arranged on the output shaft of the driving motor 14, the second rotating shaft 15 is perpendicular to the first rotating shaft 12, the driving motor 14 is used to drive the second rotating shaft 15 to rotate, the driving motor 14 is electrically connected to the controller, and the controller can control the working state of the driving motor 14; the first bevel gear 16 is sleeved on the circumference of the second rotating shaft 15; the second bevel gear 17 is sleeved on the circumference of the first rotating shaft 12, and the second bevel gear 17 is meshed with the first bevel gear 16. Working principle of the driving assembly: the driving motor 14 drives the second rotating shaft 15 to rotate, thereby driving the first bevel gear 16 thereon to rotate. Since the first bevel gear 16 is meshed with the second bevel gear 17, the second bevel gear 17 can be driven to rotate, so that the first rotating shaft 12 rotates synchronously, thereby realizing that the driving assembly works to drive the first rotating shaft 12 to rotate.

[0052] Among them, other structures of this embodiment are consistent with those of embodiment 1, and are just optimizations made to embodiment 1.

[0053] Example 3

[0054] As a further improvement scheme based on Example 1, in the above scheme, when measuring the thickness of the wall, when the two sides of the wall are uneven, it may also cause errors in the measured data. In order to avoid this situation, it also includes: the telescopic rod 5 is horizontally arranged between the first support block 1 and the second support block 2, the telescopic rod 5 is a rod with a telescopic function, similar to the handle of an umbrella, the telescopic rod 5 is located below the first support rod 11 and the second support rod 21, and the circumferential sleeve of the telescopic rod 5 is provided with a spring 51, and the two ends of the spring 51 are respectively fixed to the two ends of the telescopic rod 5. When in use, the spring 51 is in a stretched state and has a rebound force to shrink back. When measuring the thickness of the wall, the telescopic rod 5 and the spring 51 are stretched, and the side opposite to the first support block 1 and the second support block 2 is pressed against the two sides of the wall. The elastic force of the spring 51 can be used to press the first support block 1 and the second support block 2 against the wall surface, and the thickness of the wall is measured by the distance measuring structure 3, so as to avoid errors in the measured data caused by the unevenness of the two sides of the wall.

[0055] Furthermore, the two ends of the telescopic rod 5 are detachably connected to the first support block 1 and the second support block 2, respectively. The detachable connection structure of the telescopic rod 5 and the first support block 1 and the second support block 2 includes: two strong magnets 52 are respectively arranged at the two ends of the telescopic rod 5, the two ends of the spring 51 are respectively fixed to the two strong magnets 52, and a ferromagnetic sheet is arranged on the opposite side of the first support block 1 and the second support block 2, and the two strong magnets 52 are magnetically adsorbed to the two ferromagnetic sheets. When measuring the height of the wall, the telescopic rod 5 is not needed, so the telescopic rod 5 can be disassembled from the first support block 1 and the second support block 2. When measuring the thickness of the wall, the magnetism of the strong magnet 52 and the ferromagnetic sheet can be used to install the telescopic rod 5 between the first support block 1 and the second support block 2.

[0056] Among them, other structures of this embodiment are consistent with those of embodiment 1, and are just optimizations made to embodiment 1.

[0057] According to the above principle, the device can determine the flatness of the wall and measure the height and thickness of the wall. When measuring the height of the wall, first stand the whole device upright so that the first support block 1 stands on the ground, and the second support block 2 is located above the first support block 1, so that the drive motor 14 works, driving the second shaft 15 to rotate, and synchronously driving the first bevel gear 16 to rotate, because the second bevel gear 17 is engaged with it, driving the second bevel gear 17 to rotate, so that the first shaft 12 rotates, and when the first shaft 12 rotates, the gear 13 at one end thereof rotates, thereby moving on the rack 24, so that the second support rod 21 can move upward relative to the first support rod 11 until the second support block 2 contacts the top surface of the wall. At this time, the bottom surface of the first support block 1 (the bottom surface of the first support block 1 when the device is turned sideways) is close to the wall. If the bottom surface of the second support block 2 If the pressure sensor 41 on the wall (the bottom surface of the second support block 2 when the device is turned sideways) receives a pressure change signal, it means that the wall is relatively flat. At this time, the data directly measured by the distance measuring structure 3 is the wall height; if the pressure sensor 41 does not receive a pressure change signal, it means that the wall is uneven. At this time, the driving member 42 is activated to drive the fixed shaft 43 to rotate, so that the rotating drum 44 rotates, thereby moving relative to the installation slot 22, driving the pressure sensor 41 to move synchronously, until the pressure sensor 41 contacts the wall. After that, the pressure sensor 41 receives a pressure change signal and sends the signal to the controller. The controller controls the driving member 42 to stop working. At this time, the actual height of the wall is calculated using the data measured by the distance measuring structure 3 and the data of the movement of the rotating drum 44. There are two ways to measure the thickness of a wall. One is the measurement method as described above, except that the entire device is placed horizontally on the ground when in use; the other is to use a strong magnet 52 to install the telescopic rod 5 between the first support block 1 and the second support block 2. Under the action of the elastic force of the spring 51, the telescopic rod 5 will shrink, and the side opposite to the first support block 1 and the second support block 2 will be pressed against one side of the wall. The second support block 2 is pulled apart so that the side opposite to the first support block 1 of the second support block 2 is pressed against the other side of the wall. At this time, the spring 51 is in a stretched state, and the elastic force of the spring 51 is used to make the first support block 1 and the second support block 2 close to both sides of the wall. The data directly measured by the distance measuring structure 3 is the wall thickness.

[0058] The advantage of the present invention is that the device is provided with a leveling structure, which can first determine whether the wall surface is flat. If the pressure sensor receives a pressure change signal, it means that the pressure sensor is in contact with the wall surface, indicating that the wall surface is relatively flat, and the height or thickness of the wall surface can be directly measured through the distance measuring structure. If the pressure sensor does not receive a pressure change signal, it means that the pressure sensor does not contact the wall surface, indicating that the wall surface is uneven. The position of the pressure sensor can be adjusted through the moving component in the leveling structure until the pressure sensor contacts the wall surface. The actual height or thickness of the wall surface can be calculated through the distance measuring structure and the distance moved by the moving component. The present device can avoid the situation where the measurement accuracy is low due to the uneven wall surface.

[0059] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
