However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate structural component; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The structure of the vertical settlement measurement system based on double crosshair visual feedback provided by this invention is described in detail below. Figure 1 The module layout relationship of a vertical settlement measurement system based on double crosshair visual feedback provided according to an embodiment of the present invention is shown.

[0022] Depend on Figure 1 As can be seen, the vertical settlement measurement system based on double crosshair visual feedback provided in this embodiment of the invention includes a data acquisition module, an image generation module, and a settlement calculation module; wherein, The data acquisition module is used to measure the tilt angle of the plane under test rotating around the X-axis. and the tilt angle of rotation around the Y-axis The image generation module is used to generate a central crosshair reference line on a preset screen, and based on the tilt angle... and the tilt angle An offset positioning crosshair is generated on the preset screen; wherein, the central crosshair baseline and the offset positioning crosshair form a double crosshair visual feedback model; the settlement calculation module is used to process the real-time input measurement point based on the double crosshair visual feedback model to generate the real-time vertical settlement of the measurement point.

[0023] In one specific embodiment of the present invention, to achieve the tilt angle of the measured plane around the X-axis by the data acquisition module... and the tilt angle of rotation around the Y-axis The measurement data acquisition module may include a triaxial accelerometer and a mathematical calculation model; wherein, the triaxial accelerometer is used to calculate the gravitational acceleration component of the plane to be measured; and the mathematical calculation model is used to calculate the tilt angle based on the gravitational acceleration component. and the tilt angle .

[0024] The following details the working principle of the triaxial accelerometer and the mathematical calculation model. When the device equipped with the triaxial accelerometer is stationary on the plane to be measured, the gravitational acceleration components of the gravity vector along the X, Y, and Z axes can be measured, denoted as Ax, Ay, and Az, respectively. The mathematical calculation model can then calculate the tilt angle of the plane to be measured about the X-axis based on the gravitational acceleration components of the gravity vector along the X, Y, and Z axes using the arctangent function arctan. (i.e., the roll angle about the X-axis) and the tilt angle about the Y-axis. (That is, the pitch angle of rotation about the Y-axis), the specific calculation formula is as follows: =arctan(Ax / Az), = arctan(Ay / Az) It should be noted that the tilt angle of the plane under test rotated about the X-axis and the tilt angle of rotation around the Y-axis Once the calculation is complete, the tilt angle based on the rotation of the plane under test around the X-axis can be determined. and the tilt angle of rotation around the Y-axis On the preset screen, using the central crosshair as a reference, an offset positioning crosshair corresponding to the plane to be measured is generated. At this time, the preset screen will display two crosshairs, namely the central crosshair reference and the offset positioning crosshair. The central crosshair reference and the offset positioning crosshair together construct a double crosshair visual feedback model (a double crosshair reference model). Under this double crosshair visual feedback model, if a real-time input measurement point is input on the plane to be measured (using the offset positioning crosshair as the initial reference), the corrected coordinates of the real-time input measurement point under the central crosshair reference can be directly calculated. Based on the corrected coordinates, the vertical settlement of the real-time input measurement point can be calculated.

[0025] It should be noted that the initial data acquired by the triaxial accelerometer for calculating the gravitational acceleration component of the plane under test contains errors. Therefore, the data acquisition module provided by this invention may further include an optimization unit. This optimization unit is used to perform noise reduction and fusion optimization on the gravitational acceleration component using a Kalman filter algorithm and a complementary filter algorithm, compensating for the inherent errors and temperature drift of the triaxial accelerometer, thereby improving the accuracy of the gravitational acceleration component of the plane under test calculated by the triaxial accelerometer.

[0026] Furthermore, the vertical settlement measurement system based on double crosshair visual feedback provided by the present invention may also include a remote monitoring module; wherein, the remote monitoring module is equivalent to a remote monitoring terminal, used to receive the real-time vertical settlement of the measurement point generated by the settlement calculation module in a control room at a certain distance from the site, and generate a corresponding real-time response based on the real-time vertical settlement of the measurement point, providing remote monitoring function for the staff in the control room.

[0027] Specifically, the remote monitoring module can be configured with an alarm module and a preset settlement threshold. When the vertical settlement of the real-time measuring point exceeds the preset settlement threshold, it indicates that the vertical settlement of the real-time measuring point has exceeded the acceptable error range. At this time, the alarm module will issue a settlement over-value alarm to remind the staff to perform leveling operations on the measuring point. When the vertical settlement of the real-time measuring point does not exceed the preset settlement threshold, it indicates that the vertical settlement of the real-time measuring point is within the acceptable error range. At this time, the alarm module will not issue a settlement over-value alarm, and there is no need to perform leveling operations on the measuring point.

[0028] It should be noted that, under normal circumstances, the control room is far from the construction site. To reduce wiring and save costs, the vertical settlement measurement system based on double crosshair visual feedback provided by this invention may also include a wireless transmission module. The wireless transmission module may include a signal transmitter and a signal receiver. The signal transmitter is located at the construction site and connected to the settlement calculation module, while the signal receiver is located in the control room and connected to the remote monitoring module. The remote monitoring module can be wirelessly connected to the settlement calculation module through the wireless transmission module.

[0029] Furthermore, to power the various modules in the vertical settlement measurement system based on double crosshair visual feedback provided by this invention, the vertical settlement measurement system based on double crosshair visual feedback provided by this invention may also include a power supply module; wherein, the data acquisition module, the image generation module, the settlement calculation module, and the wireless transmission module are all electrically connected to the power supply module, and the data acquisition module, the image generation module, the settlement calculation module, and the wireless transmission module are all powered through the power supply module.

[0030] In addition, to enable signal transmission between modules in the vertical settlement measurement system based on double crosshair visual feedback provided by the present invention, the vertical settlement measurement system based on double crosshair visual feedback provided by the present invention may also include a bus connection line. The data acquisition module, the image generation module, the settlement calculation module, and the wireless transmission module are all connected sequentially through the bus connection line, and the two connected modules transmit signals to each other through the bus connection line.

[0031] To further illustrate the manufacturing process and working principle of the vertical settlement measurement system with double crosshair visual feedback provided by the present invention, the following is a further description of the vertical settlement measurement system with double crosshair visual feedback provided by the present invention through an embodiment: Example 1: The intelligent level measurement system based on dual crosshair visual feedback and wireless transmission provided by this invention can be manufactured in the following ways: Figure 2 This embodiment illustrates the device structure of the vertical settlement measurement system based on dual crosshair visual feedback (excluding the receiver in the remote monitoring module and the wireless transmission module), as shown in the schematic diagram. Figure 2As shown, a 150mm×80mm×20mm aluminum alloy / plastic composite shell 1 is installed. A 70mm×50mm OLED display screen (i.e., the preset screen 2) is installed on the front of the shell 1. Below the screen 2, a physical button 6 (up, down, left, right, power, settings, measurement, storage) is installed for controlling the display and inputting data. On the right side of the shell 1, a memory card interface 5, a charging port 4, and a power indicator light 3 are installed. The memory card interface 5 is used to insert a memory card such as an SD card, which is used to store internal system data. The charging port 4 is used to charge the built-in power supply module, and the power indicator light 3 is used to display the power supply module's power level.

The system first initializes each hardware module and loads pre-stored calibration parameters; the microprocessor then... 2The C-bus continuously acquires raw data from the triaxial accelerometer, which is then denoised and fused using Kalman filtering or complementary filtering algorithms to calculate the effective gravitational acceleration components. Subsequently, based on a mathematical model, the tilt angles of the device's rotation around the X and Y axes are calculated in real time. and .

After the user inputs the horizontal distance L of the measuring point, the settlement calculation module (which can be implemented by a microprocessor) processes the real-time input measuring point based on the double crosshair visual feedback model to generate the real-time vertical settlement ΔH of the measuring point, which is then displayed in real time on the OLED display panel. It should be noted that during actual measurement, the user can save data such as timestamps, tilt angles, and settlement amounts to a memory card with one click (supporting CSV format and screenshots), and simultaneously send the data to the remote monitoring module via wireless transmission for remote monitoring and analysis.
