Background

In building construction, a large number of brackets are used in order to ensure that each construction process is carried out smoothly, for example, scaffolds as construction platforms, forms for temporary support as templates, and the like. Because these supports all need demolish after the construction is accomplished, when putting up the support, the partial connection structure of support adopts temporary connection mode such as ligature, spiro union for the structural stability of support is limited. Along with construction, the support can be loosened or deformed in structure due to stress change and abrasion, so that potential safety hazards are generated, and if the potential safety hazards cannot be found and eliminated in time, the support is easy to fall, collapse and other safety problems. Therefore, managing the risk that may occur during the construction of the bracket is a non-negligible important point in the construction of the building.

The invention patent application with publication number of CN115167212A discloses a foundation pit dynamic construction control system based on a monitoring platform. The system comprises an engineering visualization module, a foundation pit wireless monitoring module, a data analysis module, a theoretical analysis interaction module, a dynamic construction control module and an alarm module. The system is based on the monitoring data, and the monitoring data and a plurality of groups of theoretical calculation results are compared, so that the optimal calculation working condition is selected, and the foundation pit state change of the next stage is predicted, so that the construction safety of the next stage is ensured. And the project visualization module is used for registering project information and monitoring information, importing a foundation pit visualization model and a monitoring point number, and dynamically visualizing and displaying monitoring data of the foundation pit according to the monitoring point number through the foundation pit visualization model. And the foundation pit wireless monitoring module is used for monitoring the foundation pit, obtaining monitoring data of the foundation pit and uploading the monitoring data. The data analysis module is used for acquiring the monitoring data, preprocessing the monitoring data, obtaining a trend fitting curve of dynamic change according to the monitoring data, and carrying out foundation pit construction monitoring analysis and subsequent numerical calculation correction through the trend fitting curve.

In the prior art, risk sources are almost determined according to historical accident cases in the management and control of risks possibly occurring in the support construction process, the risk sources are monitored, and an alarm is given when the monitoring data of the risk sources exceeds a preset alarm value. The monitoring of the safety risk source in the bracket construction process in the prior art can be monitored in real time by using the monitoring device, however, the existing monitoring device is difficult to acquire information influencing construction safety such as emotion of constructors, perception of the constructors to the environment, perception of the constructors to the climate and the like through monitoring data. Therefore, when the safety inspection is performed, the safety personnel still need to feed back the emotion, environment and climate of the constructor to adjust the preset alarm value. Because of individual differences of people, different people have different perceptions on the same thing, therefore, when a new person safety officer is responsible for checking, the safety officer with rich experience is required to conduct guidance, and the differences of personal experiences lead to the fact that the evaluations of potential safety risks by different safety officers cannot be unified, so that the safety monitoring is not standard.

Preferably, when the data processing apparatus 310 determines that the settlement type belongs to abnormal settlement, a risk warning message is generated and sent to the intelligent terminal 330 worn by the constructor, so as to remind the constructor to evacuate the dangerous area or to process the potential danger.

Referring to fig. 5, the data processing apparatus 310 may preferably further include a machine learning module 313. Preferably, the image analysis module 311 is communicatively coupled to the data storage module 312 and the machine learning module 313, respectively, and the data storage module 312 and the machine learning module 313 are communicatively coupled.

Preferably, the machine learning module 313 may perform machine learning using the historical sedimentation data stored in the data storage module 312 to set the first and second thresholds. Preferably, the settlement inspection of the girder template holder 400 by the safety inspection unit 300 may be inspected at preset time intervals. For example, in the process of pouring the box girder, the image monitoring device 320 collects images of each detection point 450 every two hours, and the image analysis module 311 of the data processing device 310 analyzes the sedimentation type of the box girder template bracket 400 to determine whether to trigger early warning.

Preferably, in case of performing a settlement inspection on the girder template holder 400 using the security inspection unit 300, the image monitoring device 320 may form a video stream of images including the detection points 450 acquired in real time and transmit the video stream to the data processing device 310. Preferably, the image analysis module 311 of the data processing apparatus 310 may acquire the data of the displacement of each detection point 450 over time by tracking the position of each detection point 450 in the video stream.

Preferably, the data processing device 310 may determine the type of settlement of the box girder template support 400 based on the time delay of the displacement between the at least two detection points 450. Preferably, the time delay of the displacement between the detection points 450 may be the difference in the time taken for the detection points 450 to reach a unit displacement.

Preferably, the data processing device 310 may determine the settlement type of the girder-as-box formwork support 400 according to the difference in the time taken for the first detection point 451, the fourth detection point 454, and the fifth detection point 455 to reach a unit displacement.

Preferably, when the difference in the time taken for the first detection point 451, the fourth detection point 454, and the fifth detection point 455 to reach a unit displacement is within a preset error range, the analysis module 111 may determine that the settlement type of the girder-template holder 400 belongs to an overall uniform settlement. Preferably, the unit displacement may be 1 to 2mm. Preferably, the unit displacement may be 1mm. Preferably, the preset error range may be set to 1s to 30min. Preferably, the preset error range may be set to 2min.

Preferably, when the difference between the time taken for the fourth detection point 454 and the fifth detection point 455 to reach the unit displacement is within the preset error range, the time taken for the fourth detection point 454 and the fifth detection point 455 to reach the unit displacement is longer than the time taken for the first detection point 451 to reach the unit displacement and exceeds the preset error range, which indicates that the settling velocity of the first detection point 451 exceeds the settling velocity of the fourth detection point 454 and the fifth detection point 455, meaning that the settling velocity of the center of the girder-template bracket 400 is faster than the settling velocity of the edge of the girder-template bracket 400, the center portion of the girder-template bracket 400 may collapse. For example, the time for the fourth detection point 454 and the fifth detection point 455 to reach a unit displacement is 10min and 11min, respectively, and the time for the first detection point 451 to reach a unit displacement is 6min, indicating that the settling rate of the center of the girder template frame 400 is faster than the settling rate of the edges of the girder template frame 400, and that collapse of the girder template frame 400 may occur. Preferably, when the time taken for the fourth detection point 454, the first detection point 451, and the fifth detection point 455 to reach the unit displacement increases or decreases sequentially and the difference in the time taken for the detection point 450 to reach the unit displacement exceeds the error range, it indicates that the girder-in-box formwork support 400 is inclined and the inclination may cause the bridge to collapse. For example, when the time taken for the fourth detection point 454, the first detection point 451, and the fifth detection point 455 to reach the unit displacement is sequentially 10min, 11min, and 12.5min, the difference between the time taken for the fourth detection point 454 and the time taken for the fifth detection point 455 to reach the unit displacement exceeds 2min of the preset error range, which indicates that the bridge collapse may be caused by the inclination of the girder-template bracket 400.

Preferably, the image analysis module 311 of the data processing apparatus 310 may determine the settlement type of the girder-template bracket 400 according to the difference in time taken for the first detection point 451, the fourth detection point 454, and the fifth detection point 455 to reach a unit displacement. When the image analysis module 311 determines that the bridge collapse may be caused by the girder support 400, the image analysis module 311 generates a prompt instruction and sends the prompt instruction to the intelligent terminal 330 worn by the constructor, so that the constructor strengthens the foundation corresponding to the detection point 450 with the faster sedimentation rate by increasing the number of the first rods 410 and strengthening the connection between the first rods 410, thereby slowing down the sedimentation rate of the detection point 450.

Preferably, on the basis of the timing inspection, the constructor may also send an inspection execution instruction to the data processing device 310 through the intelligent terminal 330, so that the data processing device 310 acquires images of the respective inspection points 450 by using the image monitoring device 320 to determine the settlement type of the girder-box formwork support 400.

Preferably, the construction person as a person is also a sensor with perception compared to several sensors provided. The constructor is aware of the existence, so that information which is not fed back by the data can be perceived. Such as the constructor's mood, perception of the environment, perception of the climate, etc., which information is not visually tested by the sensor. For example, wind speed, humidity, emotion fluctuation of constructors, etc. of a construction site when casting the box girder have an influence on the construction safety inspection of the box girder formwork support 400.

However, the prior art has less hints for environmental risk because weather is changing, however, unpredictable safety risks can easily occur regardless of the environment of the construction site and the weather effect. For construction safety, prevention and reminding after the occurrence of safety risks are required to be paid at great cost. Therefore, it is necessary to give the constructor an appropriate advance notice.

Accordingly, the constructor triggers the check through the intelligent terminal 330 and supplements his/her own wanted content when not busy for editing the learning model in the machine learning module 313, and can generate more safety reminding information as well as test information.

Preferably, during the casting of the box girder, the constructor may mark the moment of interest or abnormality through the intelligent terminal 330. For example, the constructor may trigger a check and supplement his own perception information later when he feels pleasant, uncomfortable, does not feel happy, hears abnormal sounds, senses the topography of both sides of the girder template support 400. The perception information is described by constructors in natural language, and can be voice description, text description, picture description and the like. The perceived information in the pouring process of the box girder belongs to blind areas of the editors of the learning model in the machine learning module 313 and also belongs to blind areas of the current sensor, but the data are not normally represented by the box girder template bracket 400 and are absolutely safe, so that the perceived feedback of constructors with inspection experience (such as senior safety officers) is particularly important.

For example, when the box girder formwork support 400 is erected above a river, although an anhydrous construction area can be opened up by a cofferdam construction method, a dead water period construction method, and the like, a part of the river cannot be intercepted because the river has functions of irrigation, water supply, and the like, so that water flows exist in the river during the construction process, but the water flows do not influence the progress of the construction currently. This is a potential torrential flood risk, but is often not fed back in the running log generated by the data storage module 312 of the data processing device 310, creating a security risk dead zone. Therefore, the construction environment is necessary to be perceived, the safety condition of the construction environment is required to be updated in time, and constructors can certainly give timely perception feedback.

In the above scenario, the constructor can trigger the inspection through the intelligent terminal 330 after seeing the water flow change, and perform the perceived feedback of "water flow fast", "the water flow muddy" on the inspection trigger through the voice.

After the inspection log after the trigger inspection and the perception feedback information of the constructor are acquired, the data can be reviewed again by a person, and even the box girder template support 400 is inspected to judge whether the potential safety risk exists. Meanwhile, the perception feedback information of the constructor is also edited into the learning model in the machine learning module 313. Preferably, a bayesian network is introduced into the learning model to determine the causal relationship between the perceptual feedback information and the safety of the box girder template support 400, thereby increasing the variety of data that are focused on in the learning model. Preferably, the learning model updated by machine learning using the perception feedback information of the constructor can set the threshold value and the preset error range based on the perception feedback information, so that the constructor can realize real safety inspection using the safety inspection unit 300.
