Therefore, the utility model aims to provide an integrated device for measuring the inclination of a pile body, which can monitor the verticality of a single pile in real time during the actual pile sinking process, and feed back the monitoring data to the back-end processing host in real time to ensure that the pile foundation construction meets the corresponding regulations and specifications.

[0022] Before introducing the technical solution of the present invention, it is necessary to explain the background of the invention. It is common that with the rapid development of social economy, the development scale of the construction industry has been broadened. Taking the construction of offshore wind power projects as an example, the installation requirements of offshore wind turbines are extremely high, and the verticality of the pile body must be guaranteed. The commonly used method for measuring the inclination is to observe the inclination data of the pile body through a total station. However, since the benchmark of the total station is established on the ground, the measurement accuracy is easily affected by the pile foundation construction, the measurement speed is slow, and the total station is not easy to move with the mechanical movement of the pile driver, and it is difficult to keep up with the construction rhythm, which has a serious impact on the overall pile foundation construction. Therefore, the present invention aims to provide an integrated device for measuring the inclination of a pile body, which can monitor the verticality of a single pile in real time during the actual pile sinking process, and feed back the monitoring data to the back-end processing host in real time to ensure that the pile foundation construction meets the corresponding regulations and specifications.

[0023] For an exemplary embodiment of the present invention, please refer to Figures 1 to 2An integrated device for measuring pile inclination is provided, comprising two camera platforms. The camera platforms include a base 1, a camera module 2, and a connector 3 for connecting the base 1 and the camera module 2. The connector 3 is capable of driving the camera module 2 to achieve horizontal and pitch rotation. The camera module 2 is internally provided with a posture sensor for collecting the pitch and roll angles of the camera module 2. The camera module 2 and the posture sensor transmit the collected information to a back-end processing host via Ethernet communication. In actual operation, the two camera platforms are first arranged according to distance and angle requirements. Then, the camera modules 2 of the two camera platforms simultaneously capture images of a single pile from different perspectives during the hoisting process. The images are analyzed and processed to calculate the inclination angle and direction of the pile in the coordinate systems of the two camera platforms. The posture sensor is then used to measure the pitch and roll angles of the camera modules 2 of the two camera platforms relative to the horizontal plane. Through coordinate transformation, the inclination of the pile relative to the horizontal plane is obtained.

[0024] It should be noted that the two sets of camera platforms are spaced 20-30m apart from the pile. Furthermore, the intersection angle of the optical axes of the two sets of camera platforms is 70-110 degrees. Figure 1 and Figure 2 First, the base 1 of each camera platform is fixedly mounted on the mounting plane via a first fastener to serve as a mounting foundation. The connector 3 comprises a rotating platform 31 disposed on the top surface of the base 1, and a rotating arm disposed on the top surface of the rotating platform 31; the rotating arm comprises a first rocker arm 32 fixed to the top surface of the rotating platform 31, and a second rocker arm 33 hinged to the first rocker arm 32; and the camera module 2 is fixed to the top of the second rocker arm 33. Thus, the rotating platform 31 is disposed on the top surface of the base 1, the first rocker arm 32 is disposed on the top surface of the rotating platform 31, and the top of the second rocker arm 33 hinged to the first rocker arm 32 is connected to the camera module 2 via a second fastener. Thus, the preliminary assembly of the integrated device for measuring the inclination of a pile is completed. It should be noted that, in this embodiment, the first rocker arm 32 and the second rocker arm 33 are U-shaped as a whole and are bilaterally symmetrical structures to enhance the connection strength of the connecting member 3; the present invention does not make specific limitations on this. In some other embodiments, the first rocker arm 32 and the second rocker arm 33 may also be single-rod structures as long as they meet the connection requirements.

[0025] Furthermore, in some embodiments, the rotating arm is equipped with a rotating fulcrum 34 and a limiting slot 35 for displacement of the rotating fulcrum 34. Figure 2In this embodiment, the first rocker arm 32 is provided with an arc-shaped limiting groove 35, and the second rocker arm 33 is provided with a rotating fulcrum 34 to limit the rotation range of the second rocker arm 33; of course, the utility model does not limit the specific positions of the rotating fulcrum 34 and the fiber groove, as long as the limiting function is satisfied; similarly, a similar structure is also provided between the first rocker arm 32 and the rotating pan-tilt platform 31 to assist in realizing the horizontal rotation function of the first rocker arm 32, which will not be repeated here. In this way, through the cooperation of the rotating pan-tilt platform 31, the first rocker arm 32 and the second rocker arm 33, the connecting member 3 can realize horizontal and pitch rotation.

[0026] It should be noted that the camera module 2 uses a 12-megapixel high-resolution industrial camera equipped with a telephoto lens. This industrial camera uses a data cable to transmit the image of the pile body to the back-end processing host system to measure the image inclination of the pile body. In some embodiments, the posture sensor uses a MEMS (micro-electromechanical system) tilt sensor to collect the platform inclination of the camera module 2. The use of MEMS technology avoids the necessary large-scale mechanical moving parts of traditional tilt sensors, which makes the integrated device for measuring the inclination of the pile body easy to package and miniaturize, and greatly improves the overall protection and reliability. Thus, the measurement result of any camera platform can be obtained: pile body inclination = image inclination - platform inclination; further, the two sets of camera platforms are horizontally perpendicular to each other, and the pile body is measured separately to obtain the inclination on two horizontally perpendicular planes. The two results are vector-summed by the back-end processing host to finally obtain the vector of the pile body inclination, that is, the magnitude of the pile body inclination and the direction of the pile body inclination.

[0027] In some embodiments, the camera platform further includes a controller that utilizes differential level triggering to drive the camera module 2 for image capture and can also utilize differential drive to control the pan and tilt rotations of the connector 3. As a preferred technical solution, two sets of camera platforms are cascaded via a TTL-to-differential signal converter to achieve synchronous triggering with an accuracy of less than 5ms. This ensures that the two camera platforms can monitor and capture images at approximately the same time, thereby improving the measurement accuracy of the device.

[0028] It should be noted that the camera module uses a 12-megapixel high-resolution industrial camera equipped with a telephoto lens. This industrial camera uses a data cable to transmit the image of the pile body to the back-end processing host system to measure the image inclination of the pile body. In some embodiments, the posture sensor uses a MEMS (micro-electromechanical system) tilt sensor to collect the platform inclination of the camera module. The use of MEMS technology avoids the necessary large-scale mechanical moving parts of traditional tilt sensors, which makes the integrated device for measuring the inclination of the pile body easy to package and miniaturize, and greatly improves the overall protection and reliability. Thus, the measurement result of any camera platform can be obtained: pile inclination = image inclination - platform inclination; further, two sets of camera platforms are horizontally perpendicular to each other, and the pile body is measured separately to obtain the inclination on two horizontally perpendicular planes. The two results are vector-summed by the back-end processing host to finally obtain the vector of the pile body inclination, that is, the magnitude of the pile body inclination and the direction of the pile body inclination.

[0029] In some embodiments, the camera platform also includes a controller that uses differential level triggering to drive the camera module to capture images and can also use differential drive to control the horizontal and pitch rotations of the connector. As a preferred technical solution, the two camera platforms are cascaded via a TTL-to-differential signal converter to achieve synchronous triggering with an accuracy of less than 5ms, ensuring that the two camera platforms can monitor and capture images at approximately the same time, thereby improving the measurement accuracy of the device.

[0030] In summary, the integrated device for measuring the inclination of a pile body using the present invention has the following technical advantages: 1. This camera platform integrates a base, connectors, a camera module, a posture sensor and a controller in an integrated design, and has the characteristics of high integration, compact structure and easy assembly; 2. High-precision measurement: a 12-megapixel high-resolution industrial camera is used in combination with a telephoto lens to obtain images with small distortion, high pixel resolution and high measurement accuracy; 3.

Strong adaptability: this device is spaced apart from the pile body and is not affected by the displacement and inclination of the pile driver, so that this device can perform continuous and rapid inclination measurements and record the results, and the operation method is simple and easy to understand.
