With the continuous development of cities, new buildings are continuously drawn up to refresh the appearance of the cities. People easily see the style of the shrunken building, but have difficulty in paying attention to the risk during the construction of the building.

In the building construction site, large-scale construction facilities such as tower cranes, excavators, mixer trucks are many, and temporary construction facilities such as scaffolds, rainsheds, simple houses are many. These particularities of the construction environment at the construction site make the risk of accidents far higher than other working environments.

The embodiments of the present application will be described in further detail with reference to the drawings attached hereto.

In the traditional building construction process, the manual participation can not be avoided. The construction site is full of various dangerous factors, and potential threats are caused to the safety of constructors. Among various types of accidents occurring at a construction site, accidents caused by scaffolds occupy a part. Due to the structural relevance, several people will be injured and killed when the collapse occurs. The scaffold originally serves as a facility for protecting the building without the provision of constructors in the construction process, but is made to be a large hazard source through irregular design, construction and use.

At present, Building Information Modeling (BIM) technology is widely applied to the Building field, and the efficiency of related work in the field is greatly improved by the characteristics of visualization, coordination, simulation, optimization, charting and the like. Moreover, the functions of the building are gradually expanded to meet the requirements of actual building scenes.

The method is based on further expansion and application of a BIM model technology, and safety detection aiming at the full life cycle of the scaffold is developed by taking the construction progress as a main line from the design of the scaffold. The design detection efficiency of the scaffold is improved by means of the BIM technology, the safety of the scaffold in the building construction process is further improved, and a comprehensive safety guarantee is provided for constructors as much as possible.

And after the design is finished, uploading the design data of the scaffold to the electronic equipment.

And if the partial design is not in accordance with the requirement, feeding back to the designer. And uploading the design result to the electronic equipment again after the designer performs corresponding adjustment, and performing subsequent work of constructing the BIM model until the integral design is determined to meet the design requirements.

The electronic device may be a computer, a smart phone, or other device with computing capabilities.

Specific implementations of the present application may refer to the following examples.

Fig. 2 is a flowchart of a design detection method based on BIM according to an embodiment of the present disclosure, and the method of the present embodiment may be applied to an electronic device in the above scenario. As shown in fig. 2, the method includes:

s201, determining a BIM model of a construction site; the BIM model of the construction site comprises at least one BIM model of a building under construction.

Generally, the scaffold needs to be attached to a corresponding building structure for setting. Therefore, in the design stage, a building-in-building BIM model is generally constructed first, and then the scaffold design is performed on the basis of the building-in-building BIM model. In the application, "building under construction" refers to a building which needs to be designed and built by a scaffold in the process of construction in a current construction site.

By determining the BIM model of the building under construction, the erection form of the scaffold can be clarified.

S202, scaffold design data of the building under construction are obtained.

If the scaffold design of the building under construction is a two-dimensional design based on drawings, the design data can be recorded into the electronic equipment in a manual data recording mode; if the scaffold design of the building under construction is a two-dimensional design based on two-dimensional software, scaffold design data can be directly obtained by obtaining corresponding data in the two-dimensional software.

S203, determining the type of the required members of the scaffold, the number of each required member, the size of each required member, the assembly position relationship between each required member and the building under construction according to the scaffold design data.

Basic design information such as the length, the number, the assembly relation, the material, the model and the like of the components is generally included in the scaffold design data. By analyzing the data, the information such as the type of the members required for building the scaffold according to the current scaffold design data, the number of each required member, the size of each required member, the assembly position relationship between each required member and the building under construction and the like can be determined.

S204, judging whether the scaffold design is in compliance based on scaffold setting standards according to the types of the members required by the scaffold, the number of each required member, the size of each required member, the assembly position relation between each required member and a building under construction.

Whether the type of construction required by the scaffold meets the type specified by the scaffold setting standard or not is compared, whether the quantity of each required member meets the quantity specified by the scaffold setting standard or not is compared, whether the size of each required member meets the size specified by the scaffold setting standard or not is compared, whether the assembly position relation between the required members meets the relation specified by the scaffold setting standard or not is compared, whether the assembly position relation between the required members and the building under construction meets the relation specified by the scaffold setting standard or not is compared, and whether the current scaffold design is in compliance or not can be determined.

The scaffold setting standard is a technical standard adopted in the current construction site, and can be a universal standard promoted in the industry.

In some embodiments, the information of the type of the standard member, the number of each member, the size of each member, the assembly position relationship between the members and the building under construction, and the like required by the scaffold setting standard can be embodied in advance by adopting the corresponding members and the member combination. These components may be referred to as standard components and the combination of these components as a standard combination.

For example, in the standard for setting scaffolds used in the field, it is specified that the vertical rods (also called vertical posts, standing rods, skyscraper rods, vertical rods, etc., which are the main stressed rod members of the scaffold and are used for transmitting all the load on the scaffold boards to the ground through the base and the base plate) are perpendicular to the ground. The cross braces (also called cross braces and cross covers, which refer to two crossed diagonal rods arranged outside the scaffold and are used for connecting the scaffold into a whole, bearing the horizontal acting force of the scaffold and enhancing the integral stability of the scaffold) form an included angle of 45-60 degrees with the ground. And, the maximum number of cross braces spanning a pole is related to the tilt angle. When the cross braces and the ground form an inclination angle of 45 degrees, the maximum number of the cross braces crossing the vertical rods is 7; when the cross braces and the ground form an inclination angle of 50 degrees, the maximum number of the cross braces crossing the vertical rods is 6; when the cross braces form an inclination angle of 60 degrees with the ground, the maximum number of the cross braces spanning the vertical rods is 5. The components that can be preset according to this include: a vertical rod vertical to the ground and a cross brace with an inclination angle of 45-60 degrees with the ground. According to different quantitative relationships between two members, the member combinations that can be preset include: the cross bracing pole setting combination corresponds to different inclination angle ranges and different pole setting quantities.

Correspondingly, in the above S203, the information of the type of the required member, the number of each required member, the size of each required member, the assembling position relationship between the required members and the building under construction, and the like, which are acquired from the scaffold design data, can be directly embodied by using the corresponding members and member combinations in a similar manner. These components may be referred to as design components and the combination of these components as a design combination.

In this step, when the compliance is determined, the design component and the design combination are compared with the standard component and the standard combination to determine whether the design data is in compliance.

Specifically, it is possible to search for whether there is a design component identical to each standard component, and determine whether each parameter of the identical design component is identical to the standard component; and searching whether a design combination identical to the component exists or not aiming at each standard combination, and judging whether all parameters of the design combination identical to the component are identical to the standard combination or not.

Still corresponding to the above example, if a component with a cross brace is found in the design component, it is further determined whether each parameter of the design component of the cross brace is the same as each parameter of the standard component of the cross brace, and if the inclination angle of the design component of the cross brace is found to be 45 ° and the standard component of the cross brace includes the parameter of 45 °, it is determined that the component with the cross brace is compliant. If a cross brace and upright rod combination is found in the design combination, but after comparison, the cross braces in the design combination have an inclination angle of 45 degrees, and the number of upright rods is 8, the design combination is obviously different from the standard combination, which indicates that the design combination is not in compliance.

After the compliance judgment is carried out, the next operation can be carried out according to the judgment result.

S205, if the scaffold design compliance is determined, building a BIM model of the scaffold based on the BIM model of the building under construction based on the type of the members required by the scaffold, the number of each required member, the size of each required member, the assembly position relationship between each required member and the building under construction.

Through the judgment of S204, if the scaffold design is determined to be in compliance, the BIM modeling of the scaffold can be performed according to the current scaffold design data. The BIM model of the scaffold is supported by the BIM model of the building under construction, and can achieve the effect of matching with the BIM model of the building under construction.

And S206, if the scaffold design is determined to be not in compliance, sending the determined design points and the relevant setting standards which are not in compliance to designers so that the designers adjust the corresponding design data according to the design points which are not in compliance, and judging whether the adjusted scaffold design data are in compliance again until the scaffold design is determined to be in compliance.

Through the judgment of S204, if the scaffold design is determined to be not compliant, the design points of the non-compliance are likely to have potential safety hazards. At the moment, the BIM model of the scaffold cannot be directly generated, and needs to be timely fed back to a designer for modification and adjustment. After the designer uploads the adjusted design data again, the method is executed in steps S203 and S204 to perform compliance judgment. And if the judgment result is not in compliance, feeding back the adjustment again until the compliance is judged.

Considering the matching relationship among the components of the scaffold, a designer is likely to change other design points with compliance when adjusting the design points with non-compliance. Therefore, when the adjusted design data is subjected to the compliance judgment, the judgment needs to be performed based on all the data.

According to the design detection method based on the BIM, judgment of scaffold design compliance is added before the BIM model of the scaffold is constructed, risk factors can be found and corrected in the scaffold design stage, and the design safety of the scaffold is improved. Meanwhile, the type and the number of the required members in scaffold design, the assembly position relation of each member, the assembly position relation of the corresponding building and the like are disassembled and analyzed in detail based on scaffold design data, so that the scaffold can be matched with design specifications more comprehensively, and safety problems existing in design and corresponding specific members are analyzed more carefully. The design safety of the scaffold can be further improved.

In some implementations, the building a BIM model of the scaffold based on the type of the required members of the scaffold, the number of each required member, the size of each required member, the assembling position relationship between each required member and the building under construction, and the building under construction model described above includes: judging whether the structural strength of the scaffold meets a preset requirement or not according to the type of the members required by the scaffold, the number of each required member, the size of each required member, the assembly position relation between each required member and a building under construction; and if the structural strength of the scaffold meets the preset requirement, building the BIM model of the scaffold by relying on the BIM model of the building under construction based on the type of the members required by the scaffold, the number of each required member, the size of each required member, the assembly position relationship between each required member and the building under construction.

Because of the differences in project schedules, the strength requirements for the scaffold may also vary. And scaffold design compliance also can not necessarily guarantee that the intensity of scaffold can meet the demands. Therefore, after the compliance judgment, the structural strength judgment can be performed again. Specifically, the structural strength of the whole scaffold is judged based on various attributes of the members. The intensity determination may follow conventional computational approaches.

Whether the design strength of the scaffold meets the preset requirement of the current project or not is judged, modeling can be performed if the design strength meets the preset requirement, and otherwise, structural design adjustment can be performed by feeding back to a designer.

After the scaffold design scheme is determined and modeled, the construction and use stage is about to enter. Although the above schemes try to eliminate the risk factors in design, the construction process is likely to generate loss due to use, and new risks are brought. Therefore, in other embodiments, the risk factors caused by loss in the construction process can be detected and checked.

In some embodiments, maintenance plans may be pre-planned to ensure timeliness of risk detection. Specifically, a construction progress plan of a building under construction can be obtained; making an assembly progress plan of the scaffold according to the construction progress plan; sending the assembly progress plan to a construction manager so as to assemble the scaffold according to the BIM of the scaffold and the assembly progress plan; according to the construction progress planning and the assembly progress planning, predicting the loss levels of different parts of the scaffold under different construction progresses by using a pre-trained loss prediction model; determining a maintenance period and corresponding maintenance items of the scaffold according to the loss levels of different parts of the scaffold at different progresses; and sending a maintenance prompt to the construction manager in the corresponding maintenance period so as to prompt maintenance of the corresponding maintenance project.

The assembly progress of the scaffold needs to be matched with the construction progress of the building under construction. Meanwhile, along with the progress of construction, the loss degree of the scaffold with different assembly time can be different. Therefore, the loss levels of different parts of the scaffold under different construction schedules can be predicted, and different maintenance projects corresponding to different maintenance periods can be determined according to the loss levels.

For the prediction of the loss level, a loss prediction model may be used for the prediction. The machine learning model is trained by constructing the machine learning model and collecting relevant data of scaffold structure, strength, building construction progress, scaffold assembly progress and loss levels (labels) of different parts of the scaffold under different construction progress as training samples, so that the machine learning model has the capability of predicting the loss levels, and the loss prediction model is obtained.

A corresponding maintenance plan may be developed based on the predicted wear level, and maintenance may be required when the wear level exceeds a certain threshold. And reminding a manager to maintain the corresponding maintenance project when the corresponding maintenance time is reached. The accuracy of the scaffold can not be guaranteed, but a certain detection effect can be achieved, and the problem of damage in the use process of the scaffold can be found in time.

In order to improve the prediction capability of the loss model and improve the timeliness of maintenance, the state information of each part of the scaffold can be collected in time after the scaffold starts to be constructed, and the most accurate actual loss data is obtained.

In some embodiments, relevant image information of different parts of the scaffold at different construction schedules can be acquired; performing image recognition on related image information of the scaffold by using a pre-trained member damage recognition model, and determining the damage conditions of different parts of the scaffold under different construction progresses; determining actual loss levels of different parts of the scaffold under different construction schedules according to damage conditions of the different parts of the scaffold under different construction schedules; and adjusting parameters of the pre-trained loss prediction model by utilizing actual loss levels of different parts of the scaffold under different construction schedules so as to perfect the loss prediction model.

Specifically, can carry out the image acquisition of multi-angle through setting up image acquisition equipment regularly to the scaffold frame, cut apart the image of gathering to can in time acquire the image information at the different positions of scaffold frame under the different construction progress. The construction management personnel can also carry out multi-angle image acquisition on different parts of the scaffold in the construction inspection process by sending the image acquisition reminding to the construction management personnel at regular time, and upload the acquired images to the electronic equipment. Or, the construction personnel can carry out multi-angle image acquisition on different parts of the scaffold in the construction process by sending image acquisition reminding to the construction personnel at regular time, and uploading the acquired images to the electronic equipment. Alternatively, a plurality of the above methods may be used simultaneously. On one hand, the image information of the scaffold can be more timely and comprehensively obtained by the way of acquiring the images by constructors; on the other hand, through the warning to constructor, can make it improve safety consciousness to can report in time and keep away the danger when discovering the scaffold frame and damaging.

Wherein, the specific position of each component in the image can be determined according to the setting position or the shooting angle of the image acquisition equipment. Alternatively, the specific positions of the members in the image can be determined by three-dimensionally transforming the image content and then matching the image content with the BIM model of the scaffold.

It should be noted that the term "damage", "loss" and "damage" of a component in this application refers to the difference between the current state of the component and the state of the component when the component is completely new and intact, and includes, but is not limited to: component deformation, component aging, component cracking, coating peeling, and the like.

After the image of the scaffold is acquired, the damage condition of the scaffold can be detected in an image recognition mode. Specifically, an image recognition model can be constructed; obtaining scaffold images in historical projects, setting labels with different damage conditions for the scaffold images, and taking the scaffold images as training samples to train an image recognition model; the trained image recognition model (component damage recognition model) has the capability of outputting damage conditions from the input image. The damage condition of the component can be quickly and accurately judged by using the model.

The loss levels corresponding to different damage conditions are different, and the loss level of the deformation of the component is larger than the loss level of the falling-off of the coating. Accordingly, the actual loss level can be judged according to the damage condition.

After the actual loss levels of different parts of the scaffold under different construction schedules are determined, the loss prediction model can be updated as a new sample, so that the prediction result is closer to the actual condition of the current project. In this way, the confidence of the loss level predicted based on the loss prediction model is higher, and the maintenance plan made according to the loss level prediction model is more accurate.

Subject to the limitation of the image capturing angle, the result of the actual loss level determined by image recognition may still deviate from the actual situation. In order to further improve the accuracy of the actual loss level determination, a loss detection sensor can be added to assist in the determination. Specifically, a plurality of loss sensors (strain sensors, temperature sensors, etc.) may be dispersedly disposed on the scaffold, and detection data of the loss detection sensors dispersedly disposed on the scaffold may be periodically acquired; the loss detection sensor includes a strain sensor. Correspondingly, the aforesaid according to the damage condition of the different positions of scaffold under different construction progress, confirms the actual loss level of the different positions of scaffold under different construction progress, includes: and determining actual loss levels of different parts of the scaffold under different construction progresses according to the damage conditions of the different parts of the scaffold under different construction progresses and detection data of the different parts under different construction progresses.

The strain sensor can detect structural strain of the member and determine whether the member is deformed due to over-stress. When a member is stressed for a long time and is overweight, the loss level of the member can be larger and the service life of the member is shorter. The temperature sensor may detect a temperature condition of the component, determine whether extreme weather or accidental fire conditions are likely to occur, and the like. When the temperature of a component is suddenly changed, damage can also be caused. In addition, the temperature is too high, so that fire risks can be caused, and the scaffold can be threatened to constructors.

Two sensors are listed here by way of example, and the wear sensor may also be provided as another type of sensor depending on the actual construction environment.

Therefore, the actual loss levels of different portions of the scaffold under different construction schedules can be determined more accurately by combining the identification result of the member damage identification model and the detection data of the loss detection sensor.

In some specific implementations, the determining the maintenance period and the corresponding maintenance items of the scaffold according to the wear level of different portions of the scaffold at different schedules may include: determining a member to be maintained according to the damage condition of different parts of the scaffold under the current construction progress for each maintenance period; determining a maintenance mode of each component to be maintained according to the actual loss level of the component to be maintained; and for each component to be maintained, rendering and identifying the component to be maintained in the BIM model of the scaffold in different colors according to the actual loss level of the component to be maintained, and identifying the maintenance mode of the component to be maintained in the BIM model of the scaffold.

Specifically, a component with a loss level exceeding a preset value in the current progress can be added to the maintenance project of the latest maintenance period; alternatively, the components with the highest level of wear on the current schedule may be added to the maintenance project of the last maintenance cycle. The maintenance period may be set to a fixed frequency, for example once a week; alternatively, the maintenance period may be set in view of the component wear level, e.g., when the wear level of a component exceeds a preset value, a maintenance is performed.

Wherein, the damaged component (the component to be maintained) and the specific damage condition of the damaged component can be determined according to the identification result of the component damage identification model and/or the detection result of the loss sensor. According to different actual loss levels, different maintenance modes can be carried out on the component to be maintained. For example, reinforcement members or replacement members are preferred when the members are deformed; when the component coating is stripped, a make-up coating is preferred.

In addition, for the component to be maintained, the component to be maintained can be rendered and identified in the BIM model in different colors according to the actual loss level of the component, and meanwhile, the suggested maintenance mode can be identified in the corresponding position. So as to play a visual reminding role and make the manager clear at a glance.

The above embodiment realizes the safety detection of the scaffold through the design structure of the scaffold, the loss of the members and the like. In some special environments, however, environmental conditions may also affect the safety of the scaffold, such as in windy weather. Thus, further security checks may also be made based on weather conditions.

In some embodiments, weather condition forecast data may be obtained; evaluating an operation risk index by combining the construction progress planning, the actual loss level of different parts of the scaffold at the current construction progress, weather condition estimation data, the number of scaffold operators and corresponding operation contents; and if the operation risk index is larger than the preset value, sending prompt information for stopping the operation to a manager.

Specifically, weather forecast data within several hours can be obtained in time through some applications or websites capable of forecasting weather. Weather forecast data includes, but is not limited to, temperature, humidity, probability of rain, amount of rain, wind direction, wind speed, and the like.

By combining with the construction progress planning, the number of constructors (scaffold operators) who need to operate by using the scaffold, corresponding operation content and other information can be determined.

And the operation risk index can be evaluated by combining the actual loss level of different parts of the current scaffold, weather condition estimation data, the number of scaffold operators and corresponding operation contents. The higher the actual loss level of the scaffold, the worse the weather condition, the more the number of scaffold operators, the larger the difficulty coefficient of operation content and the higher the operation risk index. The specific corresponding relation can be evaluated and set by referring to accident data in historical items.

If the operation risk index is larger than the preset value, it indicates that danger occurs with a high probability, and at this time, prompt information should be sent to a manager to indicate that the operation risk is high, and the operation is recommended to be stopped.

Through considering the structural influence of weather conditions to the scaffold, the construction risk can be more comprehensively evaluated, so that the risk can be avoided in time, and personal injury possibly caused can be reduced.

In other embodiments, the safety detection of scaffold construction can be realized by detecting the wearing condition of safety equipment of constructors. Specifically, image information of constructors can be acquired; carrying out image recognition on image information of constructors by utilizing a pre-trained safety equipment recognition model, and determining the wearing condition of the safety equipment of the constructors; and aiming at each constructor, if the constructor is determined not to wear a safety helmet and/or a safety rope, sending image information of the constructor to a manager so that the manager can remind the constructor to wear safety equipment, and/or transmitting the image information of the constructor to an identity recognition model so as to recognize the identity information of the constructor, and reminding the constructor to wear the safety equipment according to the identity information of the constructor.

An image acquisition device can be arranged at a corresponding position to acquire image information of constructors and upload the image information to the electronic equipment. The electronic equipment utilizes the safety equipment recognition model trained in advance to recognize and judges whether the constructor wears various safety equipment, such as a safety helmet, a reflective vest, a safety rope, an epidemic prevention mask and the like. And reminding constructors who do not wear the safety equipment correctly so as to take protective measures.

The safety equipment identification model can adopt an image identification model. Constructing an image recognition model in advance; and (3) training the image recognition model by using some images containing constructors as training samples after setting labels according to the wearing condition of the safety equipment. The trained image recognition model (safety equipment recognition model) has the capability of directly judging whether the safety equipment is worn correctly according to the image of the constructor.

The method for reminding the constructors can be that the image information of the constructors who do not wear the safety equipment correctly is directly sent to the manager, and the manager identifies and reminds the constructors. The method for reminding the constructors can be that an identity recognition model is set after a safety equipment recognition model, image information of constructors who do not wear the safety equipment correctly is input into the identity recognition model for identity recognition, after the identity information is determined, contact information of the constructors is obtained from a constructor information database, and the constructors are directly reminded.

Through the identification and the reminding of the wearing condition of the safety equipment, the safety protection condition of constructors in a construction site can be found in time, the reminding is carried out in time, and the accidents caused by the fact that the constructors neglect the safety problem carelessly at one time are avoided.
