[0024] Exemplary method

[0025] As a first aspect of the application, the application provides a truss inspection method based on a building information model, Figure 1 As shown in the figure, a truss inspection method based on a building information model provided by an embodiment of the application is a flowchart of the method, and the method comprises the following steps: Figure 1 As shown in the figure, a truss inspection method based on a building information model comprises the following steps:

[0026] S1: Obtain current status data of the truss at the current time;

[0027] Specifically, the current status data includes but is not limited to stress data at each position in the truss structure and three-dimensional data of the truss structure. The stress data can reflect the state data at each position in the truss structure, for example, whether the material at a certain position in the truss structure has changed, thereby causing the stress to change, and whether the connection between two supports in the truss structure has changed, etc. The three-dimensional data can reflect the state data of the macro structure of the truss structure, for example, whether a certain support in the truss structure is inclined, etc.

[0028] S2: Obtain initial building information model data of the truss;

[0029] Specifically, the building information model (BIM) is a dynamic "data warehouse" containing geometric information (such as size, shape) and non-geometric information (such as material properties, cost data, construction progress) by digitally representing the physical and functional characteristics of a building.

[0030] The initial building information model data (initial BIM model data) of the truss can be the building information model data of the truss when the truss is designed using the building information model.

[0031] S3: Input the current status data into the building information model for simulation calculation to generate current building information model data;

[0032] The current status data is input into the building information model for simulation calculation to generate the current building information model data. For example, the current three-dimensional data of the truss is input into the building information model for simulation calculation to generate the current three-dimensional structure of the truss, so that the current building information model data can be obtained.

[0033] Optionally, the current three-dimensional data includes current three-dimensional image data and current three-dimensional point cloud data. Then, S3 (inputting the current status data into the building information model for simulation calculation to generate the current building information model data) specifically includes the following steps:

[0034] S310: inputting the current three-dimensional image data and the current three-dimensional point cloud data of the truss into the building information model for simulation calculation to generate the current building information model structure data.

[0035] The current three-dimensional image data can be obtained by three-dimensional shooting of the truss by using a three-dimensional camera.

[0036] The current point cloud data can be obtained by laser scanning of the truss by using a laser radar.

[0037] The current status data of the truss is obtained by using the current three-dimensional image data and the current three-dimensional point cloud data, and the current three-dimensional image data and the current three-dimensional point cloud data are simulated and calculated by using the building information model to generate the current building information model structure data of the truss, so as to reflect the structure of the truss.

[0038] S4: determining the inspection result information of the truss according to the current building information model data and the initial building information model data.

[0039] The inspection result information of the truss is determined according to the current building information model data and the initial building information model data, for example, whether the support in the truss is inclined, whether the stress in the truss is concentrated, etc.

[0040] The truss inspection method based on the building information model provided in the application adopts the building information model to design the truss and record the initial building information model data, obtains the current status data (such as three-dimensional data, stress distribution data, etc.) of the truss at all times during the hoisting operation of the truss, simulates and calculates the current status data by using the building information model to determine the current building information model data, and finally determines the inspection result information of the truss according to the current building information model data and the initial building information model data, so as to obtain whether the truss is damaged during the hoisting operation, etc. The accuracy of the safety monitoring of the truss during the hoisting operation can be accurately monitored, and the safety during the hoisting operation of the truss is improved.

[0045] S4 (determining the inspection result information of the truss according to the current building information model data and the initial building information model data) specifically comprises the following steps:

[0046] S41: performing deviation calculation according to the current building information model structure data and the initial building information model structure data in the initial building information model data to generate structure deviation data;

[0047] Specifically, the structure deviation data refers to the deviation of the same structure in the truss, for example, the angle difference between the current angle value and the initial angle value of the angle between two connected supports in the truss. Also for example, the angle difference between the current angle value and the initial angle value of the angle between the support and the horizontal line in the truss.

[0048] S42: determining the damaged structure according to the structure deviation data;

[0049] According to the structure deviation data, it can be determined whether the truss has deviated and, if it has deviated, the damaged structure according to the deviation data.

[0050] For example, when the angle difference between the current angle value and the initial angle value of the angle between the support and the horizontal line in the deviation data is greater than 0, it means that the support has tilted, and the support is determined as the damaged structure.

[0051] S43: determining the damage factor of the damaged structure according to the current stress data set of the truss, the initial stress data set in the initial building information model data and the structure deviation data;

[0052] After determining the specific damaged structure according to the structure deviation data, the damage factor of the damaged structure can be determined according to the current stress data of the truss, the initial stress data set in the initial building information model data.

[0058] Optionally, S43 (determining damage factors of the damaged structure according to the current stress data set of the truss, the initial stress data set in the initial building information model data, and the structural deviation data) specifically includes the following steps:

[0060] Specifically, the current stress data set includes a structural position of the truss and a stress value corresponding to the structural position.

[0062] (1) For each structural position on the truss where an ultrasonic stress detection device has been deployed, the ultrasonic stress detection device emits an ultrasonic wave at each specified ultrasonic frequency at the structural position.

[0063] Specifically, the ultrasonic stress detection device includes an ultrasonic wave generator, a transmitting probe, and a receiving probe, etc. The ultrasonic wave generator generates an ultrasonic wave at a specified ultrasonic frequency, the transmitting probe transmits the ultrasonic wave, and the receiving probe receives the ultrasonic wave. The difference between the arrival time of the transmitting wave pulse emitted by the transmitting probe and the arrival time of the receiving wave pulse received by the receiving probe is determined as the ultrasonic wave propagation time. The ultrasonic wave propagation time is the propagation time of the ultrasonic wave at the stress concentration position.

[0064] (2) Using the critical refraction longitudinal wave method, the stress value of the structural position at the specified ultrasonic frequency is calculated according to the obtained ultrasonic wave propagation time of the structural position at the specified ultrasonic frequency.

[0065] (3) For each structure position, based on the stress values of the structure position at each specified ultrasonic frequency, an average stress value and a stress value standard deviation corresponding to the structure position are obtained, and based on the average stress value and the stress standard deviation, outliers are removed from the stress values of the structure position at each specified ultrasonic frequency, and the average value of the remaining stress values after removing the outliers is taken as the stress value of the structure position.

[0067] S433: Determine the damaged structure according to the current stress concentration position and the initial stress concentration position;
