Description

Technical Field

[0001] This utility model relates to the field of calibration equipment technology, and in particular to an automatic calibration device for a level instrument based on a single-chip microcomputer. Background Technology

[0002] In current urban rail transit construction projects, the elevation of the object being measured is generally determined manually using a level. First, the level's tripod is placed securely, and then the bubble level is centered. Next, leveling rods are placed at both the object's location and a reference location, and the level readings are taken. By subtracting the two readings, the elevation difference between the object and the reference location can be obtained.

[0003] However, direct manual measurement using a level instrument is subject to certain instrument and reading errors, primarily in the following ways: Firstly, the level bead at the top of the level instrument may have a slight, imperceptible deviation, resulting in error. Secondly, the leveling rod at the measured object and reference point may not be perpendicular to the ground, or personnel may move during measurement, leading to reading and cumulative errors. When these errors accumulate, they can cause significant deviations in the final measurement results. For on-site procedures that rely on high-precision measurements, as construction progresses, the errors in subsequent procedures may become excessive and difficult to eliminate, ultimately leading to rework.

[0004] Currently, levels are mainly calibrated manually. However, manual calibration has significant errors, making it difficult to achieve high-precision calibration of levels. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide an automatic calibration device for a level instrument based on a single-chip microcomputer, in order to solve the problem pointed out in the background art that manual calibration has large errors and it is difficult to achieve high-precision calibration of the level instrument.

[0029] The movable clamp is provided with a movable plate, which is movably sleeved on the connecting screw along the axial direction of the connecting screw and located between the fixed plate and the nut.

[0043] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0044] like Figures 1-2As shown in the figure, this application embodiment provides an automatic level calibration device based on a microcontroller, including a housing 100, a microcontroller 200, a three-axis gyroscope 300, and a display device. The housing 100 has a square structure. The microcontroller 200 is installed inside the housing 100; the microcontroller 200 is an Arduino nano microcontroller 200. The three-axis gyroscope 300 is installed inside the housing 100 and electrically connected to the microcontroller 200 via DuPont wires; the three-axis gyroscope 300 is an IMU406 three-axis gyroscope 300. The display device is installed on the surface of the housing 100 and electrically connected to the microcontroller 200 via DuPont wires. The three-axis gyroscope 300 is used to detect the three-axis angle data (X-axis, Y-axis, and Z-axis) in real time and transmits the three-axis angle data to the microcontroller 200. The microcontroller 200 reads and compiles the three-axis angle data and outputs it to the display device, which displays the compiled three-axis angle data.

[0045] With the above technical solution, when calibrating a level, the outer casing 100 can be directly installed onto the level's leveling rod. Then, a three-axis gyroscope 300 detects the three-axis angle data in real time. The gyroscope 300 then transmits the three-axis angle data to a microcontroller 200. The microcontroller 200 reads and compiles the three-axis angle data and outputs it to a display device. Finally, the display device shows the three-axis angle data in real time. Technicians can intuitively understand whether the level has deviated in various directions under the current state and calibrate the level by adjusting it. This setup allows technicians to calibrate the level more conveniently and efficiently, thereby improving the level's measurement accuracy.

[0046] In one possible embodiment, the display device includes a liquid crystal display screen 410 and / or a light-emitting diode 420.

[0047] When the display device is only an LCD screen 410, the three-axis angle data compiled by the microcontroller 200 can be directly displayed on the LCD screen 410 in numerical form. The staff can intuitively understand the offset in each direction under the current state through the LCD screen 410.

[0048] When the display device is only an LED 420, the three-axis angle data is compiled by the microcontroller 200. If the offset in the current state exceeds the threshold range, the LED 420 is controlled to light up. If the offset in the current state is within the threshold range, the LED 420 is controlled to turn off. The staff can judge whether there is an offset in the current state by the lighting status of the LED 420.

[0049] When the display device includes an LCD screen 410 and a light-emitting diode 420, the LCD screen 410 and the light-emitting diode 420 simultaneously display the detection status, allowing staff to more intuitively understand the current offset status and facilitating efficient calibration of the level.

[0050] In one possible embodiment, there are six LEDs 420, each corresponding to a positive or negative direction of one of the three axes. For example, if the three-axis gyroscope 300 deviates in the negative X-axis direction and the deviation exceeds a threshold range, the corresponding X-axis LED 420 will illuminate. This configuration allows operators to more intuitively understand the deviation in each direction, facilitating efficient calibration of the level.

[0051] In one possible embodiment, the calibration device further includes a lithium battery module 500, which is installed inside the housing 100 and electrically connected to the microcontroller 200 via DuPont wires to power the microcontroller 200. To ensure that the device can operate for extended periods, the lithium battery module 500 can be a 2000mAh rechargeable lithium battery, which can operate continuously for approximately 10 hours on a single charge.

[0052] In this embodiment, the calibration device also includes a switch button 600, which is mounted on the surface of the housing 100 and connected in series between the lithium battery module 500 and the microcontroller 200 to control the power supply to the microcontroller 200. With this configuration, when the device is not needed, the switch button 600 can be turned off to disconnect the power supply, ensuring the device's battery life.

[0053] In this embodiment, the calibration device further includes a charging connector mounted on the surface of the housing 100 and electrically connected to the lithium battery module 500 via DuPont wires. This configuration allows the lithium battery module 500 to be charged when connected to an external power source via the charging connector.

[0054] In one possible embodiment, at least one side of the housing 100 is designed as an open side. Specifically, the side on which the display device is mounted and the side opposite to the display device on the housing 100 are both open sides. A cover plate 110 is detachably mounted on the open side of the housing 100, and the display device is mounted on the cover plate 110. This arrangement facilitates the mounting of structures such as a microcontroller 200 and a gyroscope on the housing 100.

[0055] In one possible embodiment, such as Figure 1 and Figure 3-5As shown, this calibration device also includes a clamping mechanism mounted on the surface of the housing 100 for connecting the leveling rod. When technicians calibrate the level, they can use the clamping mechanism to fix the calibration device onto the leveling rod of the level, making operation convenient.

[0056] The clamping mechanism in this application has two structures, which are described in detail below:

[0057] In one possible embodiment, such as Figure 1 As shown, the clamping mechanism includes a fixed clamp 710, a movable clamp 720, and several connecting screws 730. The fixed clamp 710 has a fixed plate 711, which is fixedly mounted on the surface of the housing 100. There are at least two connecting screws 730, one end of which is threaded onto the fixed plate 711, and the other end is provided with a nut 731. The movable clamp 720 has a movable plate 721, which is movably fitted onto the connecting screws 730 along the axial direction of the connecting screws 730 and is located between the fixed plate 711 and the nut 731.

[0058] With the above technical solution, when the device needs to be installed on the leveling rod, part of the leveling rod structure can be placed between the fixed clamp 710 and the movable clamp 720. Then, by rotating the connecting screw 730 through the nut 731, the movable clamp 720 is moved closer to the fixed clamp 710 until the fixed clamp 710 and the movable clamp 720 clamp the leveling rod.

[0059] In another possible embodiment, such as Figures 3-5 As shown, the clamping mechanism includes a fixed clamp 710, a movable clamp 720, a drive screw 740, a gear 750, a rack 760, and a drive block 770. The fixed clamp 710 has a fixed plate 711, which is fixedly mounted on the surface of the housing 100. The movable clamp 720 has a movable plate 721, on which at least two guide rods 722 are fixed. The fixed plate 711 has guide holes adapted to the guide rods 722, with the end of the guide rod 722 away from the movable plate 721 inserted into the guide hole, allowing the movable plate 721 to be movably mounted on the fixed plate 711 along the axial direction of the guide rods 722.

[0060] A threaded sleeve 723 is fixed on the movable plate 721, and the threaded sleeve 723 is arranged parallel to the guide rod 722. A drive screw 740 is rotatably mounted in the fixed plate 711 and is also arranged parallel to the guide rod 722. One end of the drive screw 740 is inserted into the threaded sleeve 723 and threadedly connected to the threaded sleeve 723. A gear 750 is keyed to the drive screw 740. A rack 760 is movably mounted vertically in the fixed clamp 710 and meshes with the gear 750. The fixed clamp 710 has space for the rack 760 to move, and the lower end of the rack 760 extends into the interior of the housing 100. A drive block 770 is movably mounted vertically on the surface of the housing 100. A connecting block 771 is fixed on the drive block 770, and the drive block 770 is fixed to the rack 760 through the connecting block 771. A through hole is provided on the housing 100 for the connecting block 771 to move.

[0061] With the above technical solution, when the device needs to be installed on the leveling rod, part of the leveling rod structure can be placed between the fixed clamp 710 and the movable clamp 720. Then, the drive block 770 is moved downward, and the drive block 770 drives the rack 760 to move downward. Then, through the meshing action of the gear 750 and the rack 760, the drive screw 740 is driven to rotate. Then, through the threaded connection between the drive screw 740 and the threaded sleeve 723, the threaded sleeve 723 is driven to move closer to the fixed clamp 710, thereby causing the movable clamp 720 to move closer to the fixed clamp 710 until the fixed clamp 710 and the movable clamp 720 clamp the leveling rod.
