[0017] Based on the aforementioned infrastructure site risk monitoring table and risk ranking table, a standard monitoring process and key monitoring content for infrastructure site operations are planned, resulting in a monitoring report.

[0018] The monitoring of the construction site video based on the monitoring report includes:

[0019] Delineate the monitoring scope of the infrastructure construction site;

[0020] The camera installation location and angle are determined based on the monitoring range and camera acquisition range.

[0021] Install the camera at the installation location, and adjust the camera angle based on the installation angle;

[0022] The camera is used to collect on-site monitoring video of the infrastructure project.

[0023] The monitoring report is used to monitor the on-site video of the infrastructure project.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] Please see Figures 1 to 4 This invention provides a method for identifying risks at infrastructure construction sites, comprising the following steps:

[0036] S1 classifies risky operations based on the content of on-site operations and obtains the classification results;

[0037] Specifically, the classification results include monitoring modules for crossing points, deep foundation pits, scaffolding, tower erection, overhead line installation, hoisting, and formwork. The risk operation classification methods include any one of manual classification by personnel, automatic classification using daily risk operation sheets, and automatic classification using intelligent video recognition.

[0038] The process of classifying risky operations based on the content of on-site work, and obtaining the classification results, includes:

[0039] Based on the on-site work content, the 115 risky work items were divided into the following categories: crossing point monitoring, deep foundation pit monitoring, scaffolding monitoring, tower erection monitoring, overhead line monitoring, hoisting monitoring, and formwork monitoring.

[0040] S2 calculates the risk event occurrence factor based on the classification results and on-site factors;

[0041] Specifically, the method for determining the risk event occurrence factor is as follows:

[0042]

[0043] In the formula, α is the risk event occurrence factor value under the current risk classification item, i is the i-th operational risk event, n is the total number of risk events under the current risk classification item (the total number of risks is the risk events that have occurred more than twice in the past 10 years in this region), and β is the probability value of the risk event occurring under the current environment.

[0044] S3 calculates the risk event impact factor based on the on-site factors and historical records;

[0045] Specifically, the method for determining the impact factor of risk events is as follows:

[0046]

[0047] In the formula, γ is the risk event impact factor value under the current risk classification item, i is the i-th operational risk event, n is the total number of risk events under the current risk classification item (the total number of risks is the risk events that have occurred more than twice in the past 10 years in this region), and μ is the impact value caused by the occurrence of the risk event in the current environment.

[0048] S4 obtains a monitoring report based on the risk event occurrence factor and the risk event impact factor;

[0049] The specific method is as follows:

[0050] S41 calculates the on-site risk monitoring table and risk ranking table based on the risk event occurrence factors and the risk event impact factors;

[0051] Specifically, the calculation method for risk event monitoring thresholds is as follows:

[0052]

[0053] In the formula, θ i As the threshold for risk monitoring, α i α represents the occurrence factor value of operational risk events. max α represents the maximum occurrence factor of risk events within the same work segment. min α represents the minimum risk event occurrence factor for the same work segment. avg γ represents the average occurrence factor of risk events within the same work segment. i This refers to the impact factor value of risk events.

[0054] S42 plans the standard monitoring process and key monitoring content for on-site construction operations based on the construction site risk monitoring table and the risk ranking table, and obtains the monitoring report.

[0055] S5 monitors the on-site monitoring video of the infrastructure project based on the monitoring report.

[0056] The specific method is as follows:

[0057] S51 defines the scope of on-site monitoring for infrastructure construction.

[0058] S52 sets the camera installation location and angle based on the monitoring range and camera acquisition range;

[0059] Specifically, after step S52 and before step S53, the method further includes: selecting a camera based on the distance between the installation point and the construction site; performing a resolution test on the camera; and if the test passes, proceeding to step S53.

[0060] S53 installs the camera at the installation location and adjusts the camera's angle based on the installation angle;

[0061] Specifically, a camera is installed at the installation location, and the camera angle is adjusted based on the installation angle so that the camera's monitoring image includes the construction site, thus avoiding blind spots in the monitoring of the construction site.

[0062] S54 collects on-site monitoring video of the infrastructure construction using the camera;

[0063] Specifically, the current light intensity at the construction site is collected; the parameters of the camera are adjusted based on the current light intensity; and the camera with adjusted parameters is used to collect monitoring video of the construction site.

[0064] S55 monitors the on-site monitoring video of the infrastructure project based on the monitoring report.

[0065] This invention discloses a method for identifying risks at infrastructure construction sites. The method categorizes 115 risky work items into monitoring modules for crossing points, deep foundation pits, scaffolding, tower erection, overhead line installation, hoisting, and formwork, obtaining classification results. Based on the classification results and on-site factors, it calculates risk event occurrence factors; based on the on-site factors and historical records, it calculates risk event impact factors; based on the risk event occurrence factors and impact factors, it calculates an infrastructure construction site risk monitoring table and a risk ranking table; based on the infrastructure construction site risk monitoring table and risk ranking table, it plans the standard monitoring process and key monitoring content for infrastructure construction site operations, obtaining a monitoring report; it divides the infrastructure construction site monitoring area; based on the monitoring area and camera acquisition range, it sets the camera installation location and angle; it installs the camera at the installation location and adjusts the camera angle based on the installation angle; it acquires infrastructure construction site monitoring video through the camera; and it monitors the infrastructure construction site monitoring video based on the monitoring report. This invention assists supervisors in monitoring on-site construction video through monitoring reports, reducing the professional skill requirements for supervisors. Personnel with basic skills can perform complex and specialized on-site safety supervision work, significantly improving supervisory stability compared to random personnel management.
