Description

Technical Field

[0001] The utility model relates to the technical field, in particular to an auxiliary positioning system for a movable static load test device. Background Art

[0002] In the field of engineering construction, static load testing is an important testing method widely used to assess the bearing capacity and stability of pile foundations and structures. However, the current static load testing process still faces several technical bottlenecks and operational difficulties, particularly in the movement and positioning of the test equipment, as well as test efficiency. First, traditional movable static load test equipment relies primarily on manual operation. In particular, during the movement and positioning of the equipment, testers need to repeatedly measure and manually adjust the test equipment's position. This method not only consumes a considerable amount of time and manpower, but also, due to human error, it is difficult to ensure that the test equipment remains accurately aligned with the test point during the test. Positioning errors are particularly significant in large areas or complex terrain. This unstable positioning method significantly affects the accuracy and consistency of test results. Second, static load test equipment is difficult to move in complex terrain. Traditional movable static load test equipment is difficult to maneuver in mountainous, sloping, wetland, or other complex environments and is easily restricted by the terrain, resulting in unclear path planning. Path guidance for movable static load test equipment relies primarily on manual experience, lacking effective automatic guidance or deviation correction methods. This leads to frequent path deviations, further affecting the progress and accuracy of the test. In addition, traditional movable static load test equipment lacks intelligent management, and the feedback mechanism and adjustment means during the test process are relatively lagging. Real-time monitoring and data feedback during the movement of the equipment rely on the operator's visual observation, making it difficult to adjust deviations in a timely manner. This mode of operation not only reduces the efficiency of the test, but also increases the uncertainty in the test process. With the expansion of the scale and increase in complexity of engineering construction, modern static load tests have put forward higher requirements for positioning accuracy, test efficiency and equipment automation. However, existing technologies are still difficult to fully meet these needs, especially in how to improve the autonomous positioning capability of the device, improve the precision control of the moving path, and enhance stability in complex environments. There is still much room for improvement. The existence of these problems has hindered the further development of static load test technology and has become a key problem that needs to be solved urgently in the field of engineering inspection.

[0022] Please refer to Figure 1 , an auxiliary positioning system for a movable static load test device provided by the utility model includes a base station 1 and a movable static load test device 2. The movable static load test device 2 is provided with a mobile monitoring unit 3, a path image acquisition unit 4, and a laser path guidance unit 5. The mobile monitoring unit 3 and the base station 1 respectively obtain the position information of the movable static load test device 2 and the detection point, and send the position information to the main control unit 6. The main control unit 6 controls the laser path guidance unit 5 to project the laser path according to the position information. The path image acquisition unit 4 identifies the laser path, and the main control unit 6 controls the movable static load test device 2 to move along the laser path.

[0023] Among them, the reference station 1 is fixedly installed near the point to be tested. The reference station 1 obtains its own precise geographical location by receiving external signals and processes and corrects the location data through real-time dynamic differential technology. The external signal includes a GPS signal or a local base station signal. The reference station 1 transmits its location information to the main control unit 6, which serves as a reference point for the positioning of other components in the system. Through the reference point of the reference station 1, the main control unit 6 can continuously calibrate the location information of the movable static load test device 2 to ensure that the system can maintain high accuracy in different working environments. Preferably, the number of reference stations is 1-8. The reference station 1 is also equipped with an independent power supply and wireless communication module to ensure stable operation in complex outdoor environments.

[0024] Among them, the movable static load test device 2 is used to carry the test equipment and perform static load tests. The device has the ability to move on its own, and uses a variety of sensors and positioning systems to ensure that it can accurately move and align with the detection point. The movable static load test device 2 itself is usually equipped with a four-wheel drive or track drive system. Each wheel or track has an independent drive motor, and its movement is controlled by the main control unit 6 to ensure that the device can accurately locate the point to be detected. A mobile monitoring unit 3, a path image acquisition unit 4 and a laser path guidance unit 5 are installed in different parts of the movable static load test device 2. Through the collaborative work between these units, the driving path is automatically adjusted in accordance with the instructions of the main control unit 6 to complete the positioning, path identification and guidance of the movable static load test device 2.

[0025] Please refer to Figure 2 and Figure 6 , wherein the mobile monitoring unit 3 is composed of a mobile station 31 and a mobile terminal 32, which are used to monitor and obtain the location information of the movable static load test device 2 in real time, and send the information to the main control unit 6. The mobile station 31 is installed on the movable static load test device 2, and each mobile station is equipped with 2-8 positioning modules 311 and antenna modules 312, and more can be configured according to actual needs. The positioning module 311 adopts a real-time dynamic positioning system, which can accurately capture the three-dimensional spatial position information of the test device, and the antenna module 312 can ensure the stability and coverage of the received signal. The mobile terminal 32 is the data aggregation point, which is responsible for receiving the location information of multiple mobile stations and transmitting the data to the main control unit 6 through a wireless communication network, such as Wi-Fi or a cellular network. The main control unit 6 performs positioning analysis based on these real-time data, and determines the relative position between the current position of the movable static load test device 2 and the target detection point.

[0026] Please refer to Figure 3 , wherein the path image acquisition unit 4 is used to monitor the travel path of the device in real time and ensure that the movable static load test device 2 is accurately aligned with the detection point. The path image acquisition unit 4 includes more than two cameras 41 and a monitoring screen 42. The camera 41 is installed on the lower side of the movable static load test device 2. It is usually a high-definition industrial camera or a depth camera, which can provide high-resolution image data and monitor the moving path of the device within a larger field of view. The camera 41 captures the movement path of the movable static load test device 2 and its relative position with the detection point. Through the image processing algorithm, it identifies whether the movable static load test device 2 deviates from the predetermined path or fails to align with the detection point. The monitoring screen 42 is installed on the movable static load test device 2 to display the image data collected by the camera 41 in real time. The monitoring screen 42 can also integrate a path marking function to display the movement trajectory of the device and its alignment with the detection point, helping the operator to monitor the movement status of the device in real time and make manual adjustments when necessary.

[0027] Please refer to Figure 4 , wherein the laser path guidance unit 5 provides precise path guidance for the movable static load test device 2. The laser path guidance unit 5 enables the movable static load test device 2 to move along a predetermined route by projecting a laser path. The laser path guidance unit 5 includes a laser emitter 51, a laser receiver 52 and an angle adjustment mechanism 53. The laser emitter 51 is installed at the front end of the movable static load test device and emits a beam of laser light to indicate the direction of travel of the movable static load test device 2. The laser beam corresponds to the path planning of the main control unit 6 to ensure that the movable static load test device 2 moves along the correct trajectory. The laser emitter 51 can adjust the direction and angle of the laser beam in real time according to the position of the detection point to ensure that the device can correctly aim at the target. The laser receiver 52 is used to receive the reflected signal emitted by the laser emitter 51 to help the main control unit 6 determine whether the position of the movable static load test device 2 is on the predetermined path. The laser receiver 52 provides a precise position signal by measuring the reflection time or intensity change of the laser beam. The angle adjustment mechanism 53 allows the laser emitter 51 and the laser receiver 52 to adjust their angles according to different scenarios, ensuring that the laser beam is always aligned with the preset path. The angle adjustment mechanism 53 is driven by an electric servo system and can automatically adjust the angle under the command of the main control unit 6.

[0028] Please refer to Figure 5 , where the main control unit 6 is responsible for receiving and processing data information from each unit and issuing control instructions. The main control unit 6 is composed of a data processing unit 61 and an application service unit 62. The data processing unit 61 receives data from the base station 1, the mobile monitoring unit 3 and the path image acquisition unit 4, and combines the feedback information from the laser path guidance unit 5 to calculate the optimal moving path of the movable static load test device 2 through an algorithm. The data processing unit 61 usually adopts a high-performance embedded computing platform, such as the NVIDIA Jetson series, which has real-time data processing and path planning capabilities, can process large amounts of sensor data and generate corresponding control instructions. The application service unit 62 is responsible for executing the control instructions generated by the data processing unit 61, including controlling the laser path guidance unit 5 to project the laser path, adjusting the moving direction of the movable static load test device 2, etc.

[0029] Working principle: The base station 1 obtains its precise geographic location information, processes the data through real-time dynamic differential technology, and provides it to the main control unit 6 as the reference point of the system. The mobile monitoring unit 3 installed on the movable static load test device 2 monitors the location information of the device in real time and sends the data to the main control unit 6 through a wireless network. The main control unit 6 calculates the relative position of the device and the detection point based on the data provided by the base station 1 and the mobile monitoring unit 3, and generates a travel path. The laser path guidance unit 5 projects a laser path according to the instructions of the main control unit 6, instructing the movable static load test device 2 to move along the predetermined route, and at the same time feeds back the position deviation through the laser receiver 52 to ensure that the movable static load test device 2 always travels on the correct track. The path image acquisition unit 4 monitors the alignment of the movable static load test device 2 and the detection point through the camera 41, identifies the deviation of the moving path in combination with the image processing algorithm, and displays it in real time on the monitoring screen 42 for the operator to supervise and adjust. The data processing unit 61 in the main control unit 6 calculates and processes the data from each component, and controls the movement of the movable static load test device 2 through the application service unit 62 to ensure that the movable static load test device 2 accurately reaches the target detection point and completes the static load test operation.
