Description

Technical Field

[0001] The present invention relates to the technical field of equipment testing, and more specifically, to a sensor layout design method and system for a vector model. Background Art

[0002] During the equipment development process, it is necessary to conduct research or verification structural tests on certain components to verify whether the structural components meet the design requirements. Generally, sensors are arranged at specific positions on the structural parts to analyze the stress conditions of the structural parts. Testing is an important part of equipment development and requires a lot of financial resources, time and personnel. In particular, the accuracy and effectiveness of the test results mainly depend on the rationality of the design of the test implementation plan. The layout of the test sensor position and the accuracy of attachment are crucial to the test. Commonly used sensors for structural tests are strain gauge sensors, displacement sensors, temperature sensors, acceleration sensors, etc. With the continuous improvement of design requirements, the innovation of design and manufacturing methods has shortened the development cycle. However, with the increase in test tasks and the increase in test difficulty, the time spent on test verification is getting longer and longer.

[0003] If an inappropriate sensor layout is adopted, not only will it fail to accurately measure the strain signal, but it will also introduce excessive elastic signals, thus affecting the overall test results. The strain signal measured by the sensor is determined by the layout position of the sensor, so a suitable sensor layout can effectively suppress the elastic interference part of the signal. If too few sensors are arranged, important information may not be obtained, and it is difficult to reflect the dangerous conditions of the structure and the conditions of dangerous parts; if there are too many sensors, on the one hand, the cost will increase, and on the other hand, it will bring a lot of useless redundant information, which will make it very difficult to extract important information. Therefore, it is necessary to study the method of optimizing the layout, control the number and position of sensors, and save unnecessary investment while ensuring that important information is obtained.

[0004] The installation position, installation method, installation direction and attachment quality of the sensor on the test piece are very important for the successful implementation of equipment testing. The traditional method is to express the sensor layout position in the form of a file, which cannot intuitively express the sensor installation position. Workers are prone to errors when installing sensors, which leads to low work efficiency and cannot guarantee the accuracy of the installation position. The textual expression design method is not conducive to the rapid iteration and statistical analysis of design data. Summary of the invention

[0055] Vector model: It is the generalization of the point, line and surface vector model in two dimensions in three dimensions. It abstracts objects in three-dimensional space into four basic geometric elements: points, lines, surfaces and bodies in three-dimensional space, and then constructs more complex objects with a collection of these four basic geometric elements. The curve is defined by its starting point and end point, and its shape is defined by a set of value points; the surface is defined by an outer boundary ring and several inner boundary rings, and its shape is defined by a set of value curves; the body is defined by a set of surfaces to define its boundary and shape.

[0056] Sensor: A sensor is a device that can convert a physical or chemical quantity into a measurable signal output. Sensors can convert physical quantities such as light, heat, pressure, sound, and electromagnetic waves into electrical signals for easy measurement, control, and processing. The types of sensors used include pressure sensors (strain gauges), displacement sensors, temperature sensors, and acceleration sensors.

[0057] Figure 1 FIG. 1 is a flow chart showing a sensor layout design method for a vector model provided by the present invention. Figure 1 As shown, the sensor layout design method of the vector model includes:

[0058] Step S101: acquiring sensor data from a pre-established sensor database;

[0059] In the embodiment of the present invention, Figure 2 As shown in the figure, a sensor layout design method and system for a vector model is proposed, which adopts a C / S and B / S architecture.

[0062] Therefore, when designing the layout of sensors, the present invention can obtain sensor data from the corresponding sensor database, such as Figure 3 As shown. Thus, it provides data support for the subsequent sensor layout design.

[0063] Step S102: Based on the acquired sensor data, the sensor layout is designed in a three-dimensional environment, and a three-dimensional simplified graphic of the sensor is generated in the three-dimensional test model, wherein the sensor patch installer can interpret the sensor installation position, installation direction and sensor brand through the three-dimensional simplified graphic.

[0064] In an embodiment of the present invention, a three-dimensional environmental sensor layout design is provided, a three-dimensional test model (also called a digital test model) is loaded, a measuring point is selected, a sensor is designed at the measuring point position, the sensor data of the test piece model and installation direction, sensor type, brand and other attributes are selected, and a visual expression of the sensor is generated on the test piece, that is, a three-dimensional simplified graphic of the sensor. The three-dimensional simplified graphic of the sensor (also called a three-dimensional sensor design) can help the test site quickly locate the sensor position and paste it for installation. The specific steps for generating a three-dimensional simplified graphic of the sensor in the three-dimensional test model are as follows:

[0066] 2. Select the installation point, provide precise selection points and screen selection points. Precise selection is to select the pre-created points on the 3D test model. Screen selection point is to select the screen point on the surface of the test piece through mouse interaction, and project the point coordinates to the surface of the part as the sensor installation point (installpoint) position.

[0067] 3. Select the sensor installation direction:

[0068] Select the edge of the part as the reference direction, project the installation point (installpoint) onto the edge to get the tangent vector direction (direction1) of the edge in the direction of the projection point, and then project the tangent direction vector onto the tangent plane with the installation point (the tangent plane of the plane where the installation part is located at the installation point position) to get the initial installation direction (dirVec) of the sensor, such as Figure 4 As shown; if the direction needs to be adjusted, enter the adjustment angle value, and the initial installation direction (dirVec) is rotated by the input angle value on the tangent plane of the installation point according to the right-hand rule to obtain the new installation direction (dirVec);

[0069] 4. Select the sensor type, check the sensor category, and select custom types such as single strain gauge, flower strain gauge, T-shaped strain gauge, displacement sensor, temperature sensor, acceleration sensor, etc.

The serial number increases by 1 in steps of 1, and is the sensor number in sequence, recorded as abcd*. The sensor number is associated with the installation location.

[0075] 10. Create a simplified representation of the sensor strain gauge on the test piece. Take the installation point as the vertex of the strain gauge and draw a simplified model in the tangent plane along the installation vector direction and the size of the strain gauge to obtain the following: Figure 6 The simplified model shown.

[0076] For details, see Figure 7 As shown, point 4 is used as the reference, point 4 is the sensor installation point, and is a known point. In the tangent plane, the distance between point 4 and point 2 is the base X, the distance between point 4 and point 5 is the base Y, the distance between point 1 and point 2 is the grid Y, the distance between point 5 and point 6 is the grid Y, and the distance between point 3 and point 7 is the grid Y. The waist length of the 45-degree isosceles right triangle is grid Y / √2. The length between point 3 and point 9 is the same as the distance between point 6 and point 7. Connect these points 1-3-9-8-7-6-5-4-2-1, call the createLine command to create a polygon, and then call the creatFill command to fill the polygon.

[0108] 13. Select displacement sensor, then filter the type STYLE in the database to the displacement sensor database list, and select the displacement sensor brand from the displayed sensor list.

[0109] 14. Enter the initial sensor number, enter the position number 1 digit 0 and the serial number 3 digits bcd as the unique identification number of the displacement sensor. The serial number increases by a step value of 1, and is recorded as 0bcd. The sensor number is associated with the installation position.

[0110] 15. In the tangent plane where the sensor is installed, draw a circle with the installation point as the center and the diameter of the position sensor stored in the database.

[0111] 16. Select temperature sensor, then filter the type STYLE in the database to the temperature sensor database list, and select the temperature sensor brand from the displayed sensor list.

[0112] 17. Enter the initial sensor number, enter the position number 1 digit 8 and the serial number 3 digits bcd as the unique identification number of the temperature sensor. The serial number increases by a step value of 1, followed by the sensor number, recorded as 8bcd. The sensor number is associated with the installation location.

[0113] 18. In the tangent plane where the sensor is installed, draw a circle with the installation point as the center and the diameter of the temperature sensor stored in the database, and then fill the circle. The effect is as follows: Fig.11 shown.

[0114] 19. After the sensor is installed, the sensor design data is stored, including sensor number, sensor type, sensor brand, abbreviation, connection part number, sensor installation point coordinates, etc.

[0115] Optionally, the sensor layout design method of the vector model further includes: marking the distance of the sensor relative to the edge line of the installation part in the three-dimensional test model.

[0116] In the embodiment of the present invention, the sensor position is marked so that the installation personnel at the test site can prepare the patch. The distance between the sensor and the edge of the part is marked on the three-dimensional model. The vertical distance of the edge of the measured sensor installation point is used as the marked dimension.

[0117] Step S103: After the installation of the sensor is completed, the sensor number and installation position are checked in response to the inspection instruction;

[0118] In the embodiment of the present invention, after the installation of the sensor is completed, the sensor number and the installation position are checked in response to the check instruction, specifically including:

[0119] 1. Perform sensor number check to check whether there are duplicate numbers in the layout design of the sensor number. Under the same sensor type, use the digital comparison method to compare whether there are sensors with the same number. The sensor check function ensures that the sensor number is unique in the test, providing a basis for accurate data collection and analysis.

[0120] 2. Perform the sensor installation position check, input the spacing reference distance for the check, and calculate the distance between the sensor installation points according to the recorded three-dimensional coordinates of the installation points. Find the distance from the installation point N (a, b, c) to another installation point N1 (x, y, z). Use the square root of the distance formula between two points in space [(ax)^2+(by)^2+(cz)^2] to obtain the distance between the two points. Determine the size between the spacing distance and the reference distance, and the sensors that are smaller than the reference distance are displayed in the list. Selecting the sensor number in the list can locate the installation point position on the three-dimensional model and display it in the center. For sensors that do not meet the spacing requirements, the test designer makes modifications to the sensor installation position.

[0121] Step S104: After the installation of the sensor is completed, statistics are collected on the installation status of the sensor in response to the statistical instruction, and a statistical report is generated.

[0122] In an embodiment of the present invention, a sensor statistics function is provided on a part, specifically: according to the selected part, the connected parts are filtered and selected as the selected parts in the sensor design data, and the sensors installed on this part are filtered and displayed. The statistical list displays the sensor number, sensor type, sensor installation position coordinates, etc. When a sensor in the list is selected, the installation point and the simplified graphic of the sensor are displayed in the center according to the installation position, and the sensor installation status is viewed in the center of the three-dimensional model.

[0123] Furthermore, it also provides the function of statistical data of sensor design in all assemblies, specifically: it will list all sensor numbers, sensor types, sensor installation position coordinates, installed part names, etc. in the assembly, and support exporting reports in Excel format. The specific steps are as follows:

[0124] 1) Start the sensor statistics function;

[0125] 2) Choose to count based on parts or all sensors;

[0126] 3) According to the selected query conditions, find the sensor information that meets the conditions in the model, and display the relevant sensor list in the user interface;

[0127] 4) Select the sensor in the list, and the installation point will be displayed in the center of the 3D structure tree according to the installation position, and the simplified graphic of the sensor will be displayed in the center of the 3D view. The sensor installation status can be viewed in the center of the 3D model.

[0128] 5) Provide data output function, which can output the sensor list displayed in the user interface to Excel or Txt file.

[0129] Optionally, the sensor layout design method of the vector model also includes: after completing the installation of the sensor, managing the installation status of the sensor in response to a management instruction, wherein the management instruction includes at least one of the following: setting the installation status of the sensor, editing the installation status of the sensor, and deleting the installation status of the sensor.

[0130] In the embodiment of the present invention, after installing the sensor, the sensor installer at the test site can set the sensor installation status. If the sensor is installed, it will be displayed in yellow. If the sensor is not installed, it will be displayed in red. If the sensor installation status is set to a bad chip, the sensor will be displayed in black. Setting the sensor installation status can provide timely feedback to the test designer on the installation status in a three-dimensional environment. Installation status management supports setting the installation status, editing the installation status, and deleting the installation status.

[0131] Optionally, the sensor layout design method of the vector model also includes: starting the creation operation of the installation label; determining the target sensor associated with the label to be created on the test patch model of the three-dimensional digital sensor; receiving the label content of the label to be created; calling the create label command to create a three-dimensional label at the installation position of the target sensor in the test patch model, and displaying the corresponding label content at the three-dimensional label.

[0132] In the embodiment of the present invention, during the sensor installation and construction process, due to the difference between the designed sensors and the actual conditions during the installation process, the positions of some sensors may change, or some sensors do not need to be installed, or additional installations are required, etc. In order to record these on-site conditions in a timely manner and feedback to the designers, it is necessary to add an installation label function to record the on-site installation conditions on the label. This includes creating a label, editing a label, and deleting a label. The specific steps are as follows:

[0133] 1) Start creating label installation;

[0134] 2) Select the sensor to which you want to create a tag association on the 3D model;
