Description

Technical Field

[0001] The present invention relates to the technical field of highway bridge construction, and in particular to a highway bridge construction management and control system and method thereof. Background Art

[0002] During the construction of highway bridges, traditional risk management methods mainly rely on manual monitoring and experience-based judgment, which have problems such as low monitoring efficiency, inaccurate data, and untimely risk warnings.

[0003] With the continuous development of information technology, BIM technology has gradually been applied to the field of bridge construction, providing new technical means for construction risk management. The core of BIM is to establish a virtual three-dimensional model of the construction project and use digital technology to provide this model with a complete and actual construction project information database. This information database not only contains geometric information, professional attributes and status information describing building components, but also contains status information of non-component objects (such as space and motion behavior). With the help of this three-dimensional model containing construction project information, the degree of information integration of construction projects has been greatly improved, thereby providing a platform for engineering information exchange and sharing for stakeholders in construction projects.

[0004] However, the risk management and control methods for highway bridge construction based on BIM technology in the market are still not perfect. There are problems such as the risk warning model is not accurate enough and the risk warning is not timely enough. Summary of the invention

[0005] The purpose of the present invention is to provide a highway bridge construction management and control system and method thereof, so as to solve the problems that the highway bridge construction risk management and control method based on BIM technology in the current market is still not perfect, the risk warning model is not accurate enough, and the risk prompts are not timely enough.

[0006] To achieve the above object, the present invention provides a highway bridge construction management and control method, comprising the following steps:

[0007] Collect environmental data, equipment status and personnel information at the construction site;

[0008] Construct BIM models of highway bridges based on collected data;

[0009] Based on the BIM model and historical risk data, the construction area is divided into areas with different risk levels;

[0010] Establish an identity authentication database based on the collected personnel information, and install a real-time image data acquisition device at the construction site;

[0011] Use real-time image data acquisition devices and identity authentication databases to identify workers at the construction site;

[0012] Based on the image information collected by the real-time image data acquisition device, the dangerous behavior of the staff is detected in real time and an alarm message is issued;

[0013] Based on the risk assessment results, risk control measures are automatically generated and on-site managers are guided to take corresponding actions.

[0014] Among them, in the step of collecting environmental data, equipment status and personnel information of the construction site: by arranging environmental sensors and monitoring equipment at the construction site, the temperature, humidity and wind speed of the construction site are collected in real time, and the operating status of the equipment is collected, and the position information, work position and rotation information of the construction personnel are collected.

[0015] Among them, in the step of constructing the BIM model of the highway bridge with the data collected: using BIM software, according to the design drawings, actual construction data and various types of collected data, a three-dimensional model of the highway bridge is created; the three-dimensional model includes the establishment of components, the attribute information of components and the connection relationship between each component.

[0016] Among them, the specific steps in the step of dividing the construction area into areas with different risk levels based on the BIM model and historical risk data include: collecting historical risk data of highway bridge construction projects; establishing a risk assessment system based on the collected historical risk data; establishing a risk assessment model through the BIM model and the risk assessment system; and dividing the construction area into areas with different risk levels based on the risk assessment model.

[0017] Among them, in the step of establishing a risk assessment model through the BIM model and the risk assessment system, the formula of the risk assessment model is:

[0018] R=f(E,C,H)

[0019] Among them, R represents the risk level, E represents environmental factors, C represents construction complexity, and H represents historical accident data.

[0020] Among them, the specific steps of dividing the construction area into areas of different risk levels based on the risk assessment model are: standardizing the data; assigning weights to each indicator; calculating the risk score based on the indicator value and weight of each area; and dividing the construction area into different risk levels based on the risk score.

[0021] Among them, in the step of standardizing the data, the following formula needs to be used to standardize the data:

[0022] X standardized =(X-μ)÷σ

[0023] Where X is the original data, μ is the mean, and σ is the standard deviation;

[0024] In the step of assigning weights to each indicator, the analytic hierarchy process was used to determine the weights;

[0025] In the step Calculate risk score based on indicator value and weight for each region, the following formula is used to calculate the risk score:

[0026]

[0027] Where S is the risk score, W i is the weight of the ith indicator, X i,standardized is the standardized value of the ith indicator.

[0028] Among them, in the step, based on the image information collected by the real-time image data acquisition device, the dangerous behavior of the staff is detected in real time, and an alarm message is issued: the dangerous behavior includes not wearing and installing protective gear correctly, the staff entering the construction area that does not meet the risk level, the existence of dangerous work and the staff entering the construction area during non-working hours.

[0029] Among them, in the step of automatically generating risk control measures according to the risk assessment results, and guiding on-site managers to take corresponding actions: the risk control measures include strengthening safety training, adding protective measures and adjusting construction plans.

[0030] The present invention also provides a highway bridge construction management and control system, which is applied to the highway bridge construction management and control method as described above, including a data acquisition module, a risk division module, a real-time acquisition module and an alarm module. The data acquisition module is used to collect environmental data, equipment status and personnel information of the construction site, and establish a BIM model and an identity authentication database based on the collected data. The risk acquisition module is used to divide the construction area into areas with different risk levels based on the BIM model and historical risk data. The real-time acquisition module is used to collect video image data of staff in real time. The alarm module is used to issue alarm information.

[0031] A highway bridge construction control system and method of the present invention collects environmental data, equipment status and personnel information of the construction site, and establishes a BIM model and an identity authentication database based on the collected data. The construction area is divided into areas with different risk levels through the BIM model and historical risk data, and the identity of the staff on the construction site is identified using a real-time image data acquisition device and an identity authentication database to ensure that only authorized personnel can enter the corresponding risk area. If a low-risk staff member in the identity authentication database enters a medium- and high-risk area, or a medium-risk staff member enters a high-risk area, a warning message is sent to prevent the current staff member's behavior. At the same time, based on the image information collected by the real-time image data acquisition device, the dangerous behavior of the staff member is detected in real time. If the current staff member has dangerous behavior, an alarm message is issued to prevent the current staff member's behavior. Through the above method, the dangerous behavior of the staff during highway bridge construction can be accurately warned, and prompts can be given in time, so that the effect of highway bridge construction risk control is better.

If a low-risk staff member in the identity authentication database enters a medium- and high-risk area, or a medium-risk staff member enters a high-risk area, a warning message is sent to prevent the current staff member's behavior. At the same time, based on the image information collected by the real-time image data acquisition device, the dangerous behavior of the staff member is detected in real time. If the current staff member has dangerous behavior, an alarm message is issued to prevent the current staff member's behavior. Through the above method, the dangerous behavior of the staff during highway bridge construction can be accurately warned, and prompts can be given in time, so that the effect of highway bridge construction risk control is better.

[0048] Furthermore, in constructing the BIM model of the highway bridge using the data collected in step 1: using BIM software, a three-dimensional model of the highway bridge is created based on the design drawings, actual construction data and various types of collected data; the three-dimensional model includes the establishment of components, the attribute information of the components and the connection relationship between the components.

[0049] Furthermore, in the step of dividing the construction area into areas with different risk levels based on the BIM model and historical risk data, the specific steps include: collecting historical risk data of highway bridge construction projects; establishing a risk assessment system based on the collected historical risk data; establishing a risk assessment model through the BIM model and the risk assessment system; and dividing the construction area into areas with different risk levels based on the risk assessment model.

[0050] Among them, in the step of establishing a risk assessment model through the BIM model and the risk assessment system, the formula of the risk assessment model is:

[0051] R=f(E,C,H)

[0052] Among them, R represents the risk level, E represents environmental factors, C represents construction complexity, and H represents historical accident data.

[0053] Furthermore, the specific steps of dividing the construction area into areas of different risk levels based on the risk assessment model are: standardizing the data; assigning weights to each indicator; calculating the risk score based on the indicator value and weight of each area; and dividing the construction area into different risk levels based on the risk score.

[0054] Among them, in the step of standardizing the data, the following formula needs to be used to standardize the data:

[0055] X standardized =(X-μ)÷σ

[0056] Where X is the original data, μ is the mean, and σ is the standard deviation;

[0057] In the step of assigning weights to each indicator, the analytic hierarchy process was used to determine the weights;

[0061] Furthermore, in the step, based on the image information collected by the real-time image data acquisition device, dangerous behaviors of the staff are detected in real time, and an alarm message is issued: dangerous behaviors include failure to wear and install protective gear correctly, staff entering a construction area that does not meet the risk level, the presence of dangerous work, and staff entering the construction area during non-working hours.

[0062] Furthermore, in the step of automatically generating risk control measures based on the risk assessment results, and guiding on-site managers to take corresponding actions: the risk control measures include strengthening safety training, increasing protective measures and adjusting construction plans.

The data acquisition module 101 is used to collect environmental data, equipment status and personnel information of the construction site, and establish a BIM model and an identity authentication database based on the collected data. The risk acquisition module is used to divide the construction area into areas with different risk levels based on the BIM model and historical risk data. The real-time acquisition module 103 is used to collect video image data of the staff in real time. The alarm module 104 is used to issue an alarm message.

[0064] In this embodiment, the environmental data, equipment status and personnel information of the construction site are collected by the data acquisition module 101, and a BIM model and an identity authentication database are established based on the collected data. The risk classification module 102 is used to divide the construction area into areas with different risk levels through the BIM model and historical risk data. The real-time acquisition module 103 and the identity authentication database are used to identify the workers on the construction site to ensure that only authorized personnel can enter the corresponding risk area. If the low-risk workers in the identity authentication database enter the medium- and high-risk areas, and the medium-risk workers enter the high-risk areas, a warning message is sent to prevent the current workers from behaving. At the same time, based on the image information collected by the real-time acquisition module 103, the dangerous behavior of the workers is detected in real time. If the current personnel has dangerous behavior, an alarm message is issued to prevent the current workers from behaving. Through the above method, the dangerous behavior of the workers during highway bridge construction can be accurately warned and timely prompted, so that the effect of highway bridge construction risk control is better.
