Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The current commonly used precision detection mode has the following technical problems: for multipoint detection, as the number of detection points is large, the detection environment, detection time or detection condition of each detection point are difficult to ensure to be the same, so that a certain error exists in the detection result of each detection point, and the accuracy of the detection result is reduced; and corresponding to multiple detection, the detection is long in time consumption, large in workload, low in detection efficiency and high in detection cost.
In order to solve the above problems, a detection accuracy determining method based on physical simulation according to the embodiments of the present application will be described and illustrated in detail in the following specific examples.
Referring to fig. 1, a flow chart of a detection accuracy determining method based on physical simulation according to an embodiment of the present invention is shown.
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 a basic building facility.
For example, there are 20 deformation simulation devices, the measured infrastructure is a bridge, and the 20 deformation simulation devices can be respectively arranged in different areas or different places of bridge piers, bridge decks, bridge columns and the like.
Alternatively, the infrastructure may be a highway, building, tunnel, or the like.
Wherein, as an example, the detection precision determining method based on physical simulation may include:
S11, after initial positioning information of each deformation simulation device is set and dynamic detection is determined, receiving dynamic simulation data subjected to data preprocessing.
Before measurement, initial positioning information needs to be set for each deformation simulation device, and each deformation simulation device is located in the same coordinate elevation system through coordinate conversion calculation, and then subsequent detection is carried out. By setting the initial positioning information of each deformation simulation device respectively and through coordinate transformation calculation, an accurate three-dimensional displacement value under the same coordinate elevation system can be obtained, so that the detection precision of the deformation simulation device can be improved.
After the initial positioning information of each deformation simulation device is set, the detection type of the time can be determined. Optionally, the detection types include dynamic detection, static detection and manual detection of a user, and the flexibility and practicality of detection can be improved through different detection.
The dynamic detection is to detect whether the basic construction facilities are dynamically deformed, the static detection is to detect long-period deformation of the basic construction facilities, and the manual detection is to adjust the detection of each deformation simulation device under the condition of setting parameters by a user.

And step S112, setting the shaft position of the deformation simulation device in the three-dimensional direction and the included angle in the magnetic north direction by utilizing the current positioning data.
Since the infrastructure may be dynamically deformed, and the dynamic deformation may be a deformation that the deformation simulation device can bear, or may be a deformation that the deformation simulation device cannot bear, if the dynamic simulation data corresponding to the intolerable deformation is adopted, the data exceeds the bearable range of the deformation simulation device, which may cause the deformation simulation device to be damaged, and the detection of the deformation simulation device is difficult to evaluate, so as to avoid the above situation, in an embodiment, the data preprocessing may be calculating the limit value of the bearable deformation data set by the infrastructure, so as to obtain the corresponding dynamic simulation data.

In a specific implementation, a control motor is arranged in the deformation simulation device, and the control motor can control the deformation simulation device to move in different three-dimensional directions.
S22, if yes, respectively controlling each deformation simulation device to perform static physical simulation operation.
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 electric displacement adjustment, the control motors of each deformation simulation device are controlled to be started respectively, so as to control the motors to control the deformation simulation devices to move at different distances and different rates in the three-dimensional direction, and 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 controlled to receive the manual position adjustment information of the 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.
S12, calculating real-time positioning information of the deformation simulation devices based on the dynamic simulation data, and respectively and synchronously controlling each deformation simulation device to perform dynamic physical simulation operation by utilizing the real-time positioning information.

With the above embodiment, before the dynamic physical simulation, the deformation simulation device uses the intelligent terminal to perform positioning, so as to match with the positioning of the intelligent terminal, so that each offset data is unified, in an alternative embodiment, step S12 may include the following substeps:
and step 121, calculating real-time positioning information corresponding to the dynamic simulation data through coordinate conversion.
Specifically, the dynamic simulation data can be converted into three-dimensional coordinates corresponding to a guide APP of the intelligent terminal.
Substep S122, performing physical displacement in the three-dimensional direction according to the real-time positioning information synchronization.
Specifically, the physical displacement corresponding to each data included in the real-time positioning information in the three-dimensional direction may be a deformation offset, may be offset by 0.01mm to the left, 0.05mm to the bottom, 0.03mm to the right, or the like.
And step S123, recording the displacement coordinate point of the physical displacement.
And recording the displacement coordinate point of the deformation simulation device after the physical displacement.
And step S124, 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 dynamic displacement value corresponding to the three-dimensional coordinate system is obtained.
S13, synchronously acquiring the change information of each deformation simulation device when the physical simulation operation is carried out.
In an embodiment, after each deformation simulation device completes the physical simulation operation, the change information of each deformation simulation device may be obtained simultaneously in a set time node, where the change information may be a corresponding dynamic displacement value.
For example, the change information of each deformation simulation device may be acquired simultaneously after 10 seconds or 20 seconds or 30 seconds after the completion of the physical simulation operation.
S14, comparing each piece of change information with the corresponding piece of real-time positioning information to determine a detection precision value.
In an embodiment, the positioning information may further include an initial coordinate value, where the initial coordinate value may be a positioning coordinate value after each azimuth and the magnetic north direction angle are set, the change information is a dynamic displacement value, and the dynamic displacement value and the positioning coordinate value may be differenced to obtain a comparison result thereof.
For example, there are 10 deformation simulation devices, the change information of the first deformation simulation device is compared with the positioning information at the beginning of the first deformation simulation device to obtain a comparison result, then the change information of the second deformation simulation device is compared with the positioning information at the beginning of the second deformation simulation device, and so on until the change information of the tenth deformation simulation device is compared with the positioning information at the beginning of the tenth deformation simulation device, so as to obtain 10 comparison results.
And finally, determining the detection precision value of the deformation simulation system according to 10 comparison results, and adjusting the detection of the deformation simulation system.
Optionally, the difference between every two of the 10 comparison results can be calculated, if the difference is larger than a preset value, the detection precision is determined to be low, adjustment is needed, and if the difference is smaller than the preset value, the detection precision is determined to be high, and adjustment is not needed.
