All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The current commonly used precision detection mode has the following technical problems: for multi-point detection, because of more detection points, it is difficult to ensure that the detection environment, the detection time or the detection condition of each detection point are the same, so that the detection result of each detection point has a certain error, and the accuracy of the detection result is reduced; and corresponding to multiple detections, the detection consumes long time, the workload is large, the detection efficiency is low, and the detection cost is high.
In order to solve the above problem, a detection accuracy determination method based on physical simulation provided by the embodiments of the present application will be described and explained in detail by the following specific embodiments.

The method is suitable for a deformation simulation system, the deformation simulation system comprises a control terminal and a plurality of deformation simulation devices, the control terminal can be respectively connected with the plurality of deformation simulation devices, and each deformation simulation device is respectively arranged in different areas of the infrastructure.
For example, there are 20 deformation simulation devices, the measured infrastructure is a bridge, and the 20 deformation simulation devices may be respectively installed in different areas or different places such as a pier, a deck, and a bridge column of the bridge.
Alternatively, the infrastructure may be a road, building, tunnel, etc.
As an example, the detection accuracy determining method based on physical simulation may include:
and S11, after the initial positioning information of each deformation simulation device is set and the dynamic detection is determined, receiving the dynamic simulation data subjected to data preprocessing.
Before measurement, initial positioning information needs to be set for each deformation simulation device, each deformation simulation device is located in the same coordinate elevation system through coordinate conversion calculation, and subsequent detection is carried out. By setting the initial positioning information of each deformation simulation device respectively and by coordinate conversion calculation, the accurate three-dimensional displacement value under the same coordinate elevation system can be obtained, so that the detection accuracy can be improved.
After the initial positioning information of each deformation simulation device is set, the detection type of the current time can be determined. Optionally, the detection types include dynamic detection, static detection and manual detection of a user, and the flexibility and the practicability of detection can be improved through different detections.
The dynamic detection is to detect whether the infrastructure is dynamically deformed or not, the static detection is to detect the long-period deformation of the infrastructure, and the manual detection of the user is to adjust the detection of each deformation simulation device under the condition of setting parameters by the user.
If the dynamic detection is determined, the dynamic simulation data subjected to data preprocessing can be obtained, and the dynamic simulation data can be used for enabling each deformation simulation device to perform dynamic detection, so that each deformation simulation device performs dynamic physical simulation to simulate the state of the infrastructure under deformation, and detect the deformation of each deformation simulation device in the physical simulation process, and the detection precision of the deformation monitoring system can be determined according to the deformation of each deformation simulation device.
Because the positioning parameters of different devices are different, in order to ensure that the positioning information of each deformation simulation device is the same, in an embodiment, the deformation simulation device can be loaded with an intelligent terminal.

In one embodiment, the adjustment of the dynamic simulation data may be as follows:
referring to fig. 2, an operation flowchart of a detection accuracy determination method based on physical simulation according to an embodiment of the present invention is shown. In an embodiment, in order to improve the practicability and flexibility of detection, dynamic detection, static detection or manual detection can be performed.
In order to determine the operation performed by the different detection, in an embodiment, after the step of respectively setting the initial positioning information of each deformation simulation device, the method may further include:
and S21, if the non-dynamic detection is determined, judging whether the deformation simulation device carries out electric displacement adjustment.
Note that, the electric displacement adjusting deformation simulation device performs an electric movement operation.

And S22, if yes, respectively controlling each deformation simulation device to perform static physical simulation operation.
And S23, if not, respectively controlling each deformation simulation device to carry out manual movement operation.
Referring to fig. 2, if the deformation simulation devices perform the electric displacement adjustment, the control motors of each deformation simulation device are respectively controlled to start, so that the control motors control the deformation simulation devices to move at different distances and different speeds in the three-dimensional direction, coordinate change values of the deformation simulation devices are recorded in the moving process, and the coordinate change values are converted into corresponding three-dimensional coordinate values. If the deformation simulation devices do not carry out electric displacement adjustment, each deformation simulation device can be respectively controlled to receive manual position adjustment information of a user, corresponding manual adjustment is carried out according to the position adjustment information, and the adjusted change coordinates can be recorded and converted into corresponding three-dimensional coordinate values after adjustment.
And S12, calculating real-time positioning information of the simulation devices based on the dynamic simulation data, and respectively and synchronously controlling each deformation simulation device to perform dynamic physical simulation operation by using the real-time positioning information.
After the dynamic simulation data is acquired, the real-time positioning information can be calculated based on the dynamic simulation data, so that the deformation simulation device can be controlled to perform dynamic physical simulation operation based on each offset data contained in the real-time positioning information, so as to perform corresponding dynamic deformation or offset.
In connection with the above embodiment, before performing the dynamic physical simulation, the deformation simulation apparatus uses the intelligent terminal to perform positioning, and in order to match the positioning of the intelligent terminal, so as to unify the offset data, in an alternative embodiment, the step S12 may include the following sub-steps:

And a substep S123 of recording a displacement coordinate point of the physical displacement.
And then recording the displacement coordinate points of the deformation simulation device after physical displacement.
And a substep S124 of converting the displacement coordinate point into a three-dimensional dynamic displacement value.
The displacement coordinate point can be converted into a three-dimensional coordinate set by the intelligent terminal during positioning, and a corresponding dynamic displacement value under the three-dimensional coordinate system is obtained.
And S13, synchronously acquiring the change information of each deformation simulation device during physical simulation operation.
In an embodiment, after each of the deformation simulation devices completes the physical simulation operation, the change information of each of the deformation simulation devices may be simultaneously obtained in the set time node, and the change information may be a corresponding dynamic displacement value.
For example, the variation information of each of the deformation simulation devices may be synchronously acquired after 10 seconds, or 20 seconds, or 30 seconds after the physical simulation operation is completed.
And S14, comparing each change information with the corresponding real-time positioning information to determine a detection precision value.
In an embodiment, the positioning information may further include a start coordinate value, the start coordinate value may be a positioning coordinate value after setting each azimuth and magnetic north direction angle, the change information is a dynamic displacement value, and the dynamic displacement value and the positioning coordinate value may be subtracted to obtain a comparison result.

And finally, determining the detection precision value of the deformation simulation system according to the 10 comparison results, and adjusting the detection.
Optionally, the difference between every two of the 10 comparison results may be calculated, if the difference is greater than a preset value, it is determined that the detection precision is low and adjustment is required, and if the difference is less than the preset value, it is determined that the detection precision is high and adjustment is not required.
Referring to fig. 3, an operation flowchart of a detection accuracy determination method based on physical simulation according to an embodiment of the present invention is shown.
When the device is used, positioning processing and data acquisition processing to be simulated can be carried out through the intelligent terminal, then the data to be simulated are correspondingly preprocessed to obtain dynamic simulation data, then real-time positioning information is obtained through dynamic simulation data calculation, the real-time positioning information is input into each deformation simulation device, so that the deformation simulation device can control a control motor in the three-dimensional direction to carry out corresponding displacement according to the real-time positioning information (including displacement change values in the three-dimensional direction including delta X, delta Y and delta Z) to complete corresponding physical simulation operation, and finally the change values in the operation process are recorded to determine the detection precision.
