[0024] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete, and to fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, apparatus, steps, etc., can be employed. In other instances, well-known technical solutions are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0025] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0026] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all steps. For example, some steps may be broken down, while others may be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances. Furthermore, all terms such as "first," "second," etc., used below are for distinction purposes only and should not be construed as limiting the scope of this disclosure.

[0027] Figure 1 A block diagram of a standard penetration monitoring system under a floating platform according to an embodiment of this disclosure is shown schematically. (Reference) Figure 1 The standard penetration testing (SPT) monitoring system under the floating platform of this disclosure may include an inertial measurement unit, a navigation and positioning unit, at least one laser displacement sensor, a data processing unit, and a SPT adjustment system.

[0028] An inertial measurement unit (IMU) can be installed at the center of gravity of the floating platform to minimize measurement errors caused by installation misalignment. The IMU may include accelerometers, gyroscopes, and magnetometers, and can be used to measure the floating platform's inertial data, including acceleration, angular velocity, and magnetic field changes in three-dimensional space. Combined with a fusion algorithm, the floating platform's attitude information can be determined. For example, attitude information may include roll, pitch, and bow angles.

[0029] The navigation and positioning unit can be installed at the highest point of the floating platform. Considering further interference, it can also be configured to be located away from metallic obstacles and electronic interference sources to ensure good satellite signal reception. Specifically, the navigation and positioning unit can support multiple satellite navigation systems such as GPS, BeiDou, and GLONASS, enabling it to quickly and stably acquire the three-dimensional coordinate information of the floating platform, i.e., the platform's position information, even in complex environments. Furthermore, it can achieve centimeter-level or even millimeter-level positioning accuracy through differential positioning technology combined with reference station data.

[0030] Laser displacement sensors can be installed non-contactly at the connection point between the floating platform and the SPT (Standard Suppression Test Instrument), and can be used to measure the displacement changes of the SPT relative to the floating platform. The detection range and accuracy of each laser displacement sensor can be selected according to the actual SPT requirements; for example, the detection accuracy can be sub-millimeter level. By properly arranging the laser displacement sensors, the displacement of the SPT in all directions can be comprehensively monitored.

[0031] A standard penetration test (SPT) adjustment system may include a displacement adjustment device and an angle adjustment device.

[0032] The displacement adjustment device may include a servo motor, a lead screw and nut pair, and a linear guide. In other words, this embodiment of the present disclosure constructs an intelligent lifting and translation mechanism on a floating platform, consisting of a servo motor, a lead screw and nut pair, and a linear guide. For example, the accuracy of the lead screw can be 0.01 mm, and the straightness error of the linear guide is controlled within ±0.05 mm / m to ensure adjustment accuracy.

[0033] An angle adjustment device can be installed at the connection point between the displacement adjustment device and the standard penetration tester (SPT). Specifically, it may include an electric rotary joint and an angle sensor. The electric rotary joint enables automatic adjustment of the SPT angle, and the angle sensor provides real-time feedback on the SPT angle. The angle adjustment accuracy of this embodiment can reach ±0.1°.

[0034] The data processing unit can be used to acquire detection data sent by the inertial measurement unit, navigation and positioning unit and laser displacement sensor, and determine the type and degree of deviation of the standard penetration tester based on the detection data.

[0035] Figure 2 A flowchart illustrating the process for determining the type and degree of deviation of a standard penetration tester according to an embodiment of this disclosure is shown. (See also:) Figure 2 The process includes the following steps:

[0036] S202. Perform an initial calibration phase in advance to determine the initial attitude and initial position of the floating platform.

[0037] It should be understood that step S202 forms the basis for performing the standard penetration test of this disclosure. Before the specific test, initial data is determined through various units included in the aforementioned system. For example, the initial attitude of the floating platform is calibrated using an inertial measurement unit to determine the zero points of roll, pitch, and yaw. As another example, the operator places the standard penetration tester above the test point and fine-tunes its position using a displacement adjustment device to align its center with the test point. At this time, a laser displacement sensor measures the initial relative position between the standard penetration tester and the floating platform and records this information.

[0038] S204. Compare the detected attitude information with the initial attitude to obtain the attitude comparison result.

[0039] First, the detected attitude information can be compared with the initial attitude to determine the attitude difference. Next, the attitude difference can be compared with an attitude difference threshold range to determine the degree of deviation. This disclosure does not limit the specific value of the attitude difference threshold range. Then, an attitude deviation indicator can be determined based on the degree of deviation of the attitude difference relative to the attitude difference threshold, serving as the attitude comparison result.

[0040] It should be noted that using identifiers to characterize comparison results is merely an exemplary method of this disclosure, intended to facilitate subsequent processing. Alternatively, specific difference results can also be defined as attitude comparison results.

[0041] S206. Compare the detected location information with the initial location to obtain the location comparison result.

[0042] Similarly, firstly, the detected location information can be compared with the initial location to determine the location difference. Next, the location difference can be compared with a location difference threshold range to determine the degree of deviation. This disclosure does not limit the specific value of the location difference threshold range. Then, a location deviation indicator can be determined based on this degree of deviation of the location difference relative to the location difference threshold, serving as the location comparison result.

[0043] It should be noted that using identifiers to characterize comparison results is merely an exemplary method of this disclosure, intended to facilitate subsequent processing. Alternatively, specific difference results can also be defined as positional comparison results.

[0044] S208. Compare the detected displacement change with the displacement threshold range to obtain the displacement comparison result.

[0045] This disclosure does not impose any restrictions on the specific values ​​of the displacement threshold range. Similarly, the displacement comparison result can also be characterized as a displacement identifier.

[0046] S210. Determine the type and degree of deviation of the standard penetration tester based on the attitude comparison results, position comparison results, and displacement comparison results.

[0047] In exemplary embodiments of this disclosure, deviation type refers to one or more combinations of horizontal deviation, vertical deviation, and standard penetration tester displacement deviation. Each type of deviation may also have a direction; for example, for horizontal deviation, it refers to which direction the deviation occurs horizontally. This disclosure does not specifically limit this. Deviation degree refers to the magnitude of the deviation under a given deviation type. It is understood that a horizontal deviation of 20 cm due east is different from a horizontal deviation of 10 cm due east, and a horizontal deviation of 10 cm due east is also different from a horizontal deviation of 10 cm at 30° southeast.

[0048] According to some embodiments of this disclosure, a mapping relationship between attitude comparison results, position comparison results, displacement comparison results and the deviation type and degree of the standard penetration test (SPT) can be pre-constructed. After determining the specific comparison results, the deviation type and degree of the SPT can be directly determined using this mapping relationship. For example, a mapping relationship table containing this mapping relationship can be pre-stored in the data processing unit.

[0049] After determining the type and degree of deviation of the standard penetration test apparatus (SPT), the data processing unit can determine an adjustment instruction based on the deviation type and degree, and send the adjustment instruction to the SPT adjustment system. This adjustment instruction instructs the SPT adjustment system to perform the adjustment operation of the SPT to control the SPT to align with the SPT test point.

[0050] Adjustment commands can include displacement adjustment commands and angle adjustment commands.

[0051] For example, when the adjustment command includes a displacement adjustment command, the servo motor can respond to the displacement adjustment command to drive the lead screw and nut pair to control the standard penetrator mounted on the linear track to perform horizontal and / or vertical displacement.

[0052] It should be noted that different adjustment commands correspond to different adjustment operations. For example, even for horizontal displacement adjustment only, different adjustment commands correspond to different adjustment directions and degrees. This disclosure does not impose any limitations in this regard.

[0053] In addition, the monitoring system may include an impact sensing unit, which can be installed at the striking point of the standard penetration tester. This impact sensing unit is used to generate a pulse signal when the tester is struck. In this case, a data processing unit can also be connected to the impact sensing unit to identify and count the pulse signals.

[0054] Some embodiments of this disclosure also provide a scheme for determining the degree of influence of the environment in which the floating platform is located on the standard penetration test (SPT). In these embodiments, the monitoring system may further include a meteorological and hydrological sensing unit for sensing meteorological and hydrological information of the environment in which the floating platform is located, including one or more of temperature, humidity, ocean current velocity, ocean current direction, and wind speed.

[0055] In this context, the data processing unit can also be used to acquire this meteorological and hydrological information and, in conjunction with this information, determine the extent to which the environment in which the floating platform is located affects the standard penetration test.

[0056] Figure 3 A flowchart illustrating the determination of the influence of the floating platform's environment on the standard penetration test (SPT) is shown, according to an embodiment of this disclosure. (See also...) Figure 3 This process includes the following steps:

[0057] S302. Determine the primary correspondence between meteorological and hydrological information and the standard penetration test (SPT) time.

[0058] According to some embodiments of this disclosure, this correspondence can be presented using a graph, and this disclosure does not limit this.

[0059] S304. Determine a second correspondence between the number of hammer blows and the standard penetration test time.

[0060] Similarly, the correspondence between these two can also be presented, for example, using a graph.

[0061] S306. Determine the degree of influence of the floating platform's environment on the standard penetration test based on the first and second correspondences.

[0062] According to some embodiments of this disclosure, a first correspondence and a second correspondence can be shown for analysis by an analyst to determine the degree of influence.

[0063] According to other embodiments of this disclosure, the data processing unit can automatically perform analysis, for example, generating time statistics for different standard penetration test (SPT) adjustment processes to characterize the impact of applying the scheme of this disclosure on the total time of the SPT. Thus, while accurately obtaining the SPT results, the potential time costs can be assessed.

[0064] Furthermore, the various data generated during the aforementioned monitoring process can be stored on storage devices, allowing relevant personnel to query, analyze, and export this data. This data can also be uploaded to a remote server for further processing, analysis, and storage, generating detailed standard penetration test reports. Simultaneously, authorized users can log in to the remote server via the internet using computers, mobile phones, or other electronic devices to view the progress of the standard penetration test and data at each stage in real time, achieving remote monitoring and management.

[0065] Figure 4 A flowchart illustrating a standard penetration monitoring method under a floating platform according to an embodiment of this disclosure is shown schematically. (Reference) Figure 4 The monitoring method may include the following steps:

[0066] S42. Obtain the attitude information of the floating platform detected by the inertial measurement unit.

[0070] S46. Acquire the displacement change of the standard penetration tester relative to the floating platform detected by at least one laser displacement sensor.

[0071] According to some embodiments of this disclosure, at least one laser displacement sensor can be installed in a non-contact manner at the location where the floating platform is connected to the standard penetration tester.

[0072] S48. Determine the deviation type and degree of the standard penetration tester based on the attitude information, position information, and displacement changes. Determine the adjustment command based on the deviation type and degree of the standard penetration tester and send the adjustment command to the standard penetration tester adjustment system.

[0073] According to some embodiments of this disclosure, the adjustment command is used to instruct the standard penetration test (SPT) adjustment system to perform adjustment operations on the SPT device to control the SPT device to align with the SPT test point; wherein, the SPT adjustment system includes a displacement adjustment device and an angle adjustment device, the displacement adjustment device includes a servo motor, a lead screw and nut pair and a linear track, and the angle adjustment device includes an electric rotary joint and an angle sensor.

[0074] The details of steps S42 to S48 have been explained in the above description of the system and will not be repeated here.

Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or a step may be broken down into multiple steps.
