[0060] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0063] Embodiment 1

[0064] Figure 1 A schematic diagram of a railway maintenance construction safety monitoring method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, a railway maintenance construction safety monitoring method includes:

[0065] S1. Obtain a railway construction plan and extract key construction tasks in the railway construction plan.

[0066] In an embodiment of the present invention, the railway construction plan can be uploaded and obtained by specific personnel, and the railway construction plan contains data support for the subsequent extraction of key construction tasks from multiple construction tasks to improve construction efficiency.

[0067] In detail, the extracting of key construction tasks in the railway construction plan includes:

[0068] Sorting the construction tasks in the railway construction plan in chronological order to obtain sorted initial construction tasks;

[0069] Draw a task node diagram using the initial construction task;

[0070] Obtain the task duration of each initial construction task;

[0071] Calculate the earliest start time, latest start time, earliest finish time and latest finish time of each initial construction task according to the task node diagram and the task duration;

[0072] Calculate the float time of the initial construction task according to the earliest start time, the latest start time, the earliest finish time and the latest finish time;

[0073] Filter out the initial construction task with the longest completion time according to the earliest completion time and the latest completion time;

[0074] Tasks whose float time is less than a preset float time threshold are selected from the initial construction tasks as key construction tasks.

[0075] Specifically, the dependencies between the initial construction tasks are determined, which initial construction tasks must be started after other initial construction tasks are completed. Each initial construction task can be regarded as a node, and the nodes are connected by connecting lines to represent the dependencies between tasks.

[0076] The earliest start time, latest start time, earliest finish time and latest finish time of each initial construction task are calculated by the following formula: earliest start time = earliest finish time of the preceding initial construction task; earliest finish time = earliest start time + task duration; latest finish time = final finish time of the initial construction task; latest start time = late finish time - task duration.

[0077] Calculate the float time of the initial construction task to determine the maximum time each initial construction task can be postponed without affecting the completion time of the initial construction task. The calculation formula for float time is: float time = latest start time - earliest start time, or float time = latest completion time - earliest completion time.

[0078] Extracting key construction tasks from the approved railway construction plan provides an efficient process for railway construction management. By sorting the initial construction tasks, drawing the node diagram and calculating the time parameters, the key construction tasks in the initial construction tasks can be effectively identified to ensure the smooth implementation of the railway construction plan, which not only improves the efficiency of the railway construction plan, but also provides data support for subsequent construction scheduling and resource allocation.

[0079] S2. Generate an execution command according to the key construction task, and send the execution command to a preset construction work team.

[0080] In an embodiment of the present invention, a preset Eisenhower matrix is ​​used to perform priority analysis on the extracted construction action features, and an execution command is generated according to the priority sorting result, and matched with the construction work team, and finally the corresponding execution command is issued to the matched construction work team.

[0081] In an embodiment of the present invention, generating an execution command according to the key construction task and sending the execution command to a preset construction work team includes:

[0082] Extracting construction action features of the key construction tasks;

[0083] Using a preset Eisenhower matrix to perform a priority analysis on the construction action features, and obtaining a priority result of the construction action features;

[0084] The construction action features are sorted using the priority results, and execution commands are generated in sequence according to the sorted construction action features;

[0085] Sequentially performing execution matching on the execution command and the construction work team to obtain a matching result;

[0086] The execution command is sent to the matched construction work team according to the matching result.

[0087] Specifically, construction action characteristics refer to the main attributes and requirements of a specific operation or task during the construction process. The construction action characteristics include: task name, construction sequence, construction time, required resources, etc. Task name: clarify the specific content of the construction; construction sequence: the order of each construction action; construction time: the estimated time required for each action; required resources: such as manpower, materials, equipment, etc.

[0088] The Eisenhower Matrix is ​​called the Importance-Urgency Matrix, which divides the construction action characteristics of the critical construction tasks into four quadrants, and prioritizes them through the four quadrants. Quadrant I: Important and Urgent: Needs to be handled immediately, usually involving tight deadlines and major impacts; Quadrant II: Important but not urgent: Usually tasks that can be handled in a planned time; Quadrant III: Unimportant but Urgent: Can be assigned to the construction work team related to the task for urgent handling; Quadrant IV: Unimportant and Not Urgent: Minimize the time investment in these tasks.

[0089] Effectively extracting construction action features and performing priority analysis can significantly improve the efficiency and safety of construction management, help construction teams clarify the urgency and importance of tasks, ensure the rational allocation of resources and prioritize key tasks. Timely issuing commands using the preset supervision command subsystem ensures real-time monitoring and feedback of construction progress, helps dynamically adjust construction plans, and improves the overall coordination and success rate of the railway construction plan.

[0090] S3. Conduct real-time monitoring on the construction operation team that has received the execution command to obtain construction operation monitoring data.

[0091] In an embodiment of the present invention, a camera with high definition and night vision function is selected to monitor the construction work of the construction work team in real time, record and collect construction work monitoring data, and upload the collected construction work monitoring data to a remote terminal for storage, so as to provide high-quality data for subsequent analysis of the construction work monitoring data using image processing and analysis technology.

[0092] Specifically, the real-time monitoring of the construction work team that receives the execution command to obtain the construction work monitoring data includes:

[0093] Collecting real-time monitoring images of the construction work team through a preset camera;

[0094] Converting the real-time monitoring image into a grayscale monitoring image;

[0095] Performing Gaussian blur on the grayscale monitoring image to obtain a standard monitoring image;

[0096] Performing edge detection on the standard monitoring image to obtain contour information;

[0097] The construction operation monitoring data of the construction operation team is generated according to the profile information.

[0098] In detail, converting the real-time monitoring image into a grayscale monitoring image includes:

[0099] The color value of each pixel in the real-time monitoring image is converted into a grayscale value, and the formula is as follows:

[0100] Gray=0.2989×R+0.5870×G+0.1140×B

[0101] Wherein, Gray represents the grayscale value, R represents the red channel value of each pixel in the real-time monitoring image, G represents the green channel value of each pixel in the real-time monitoring image, and B represents the blue channel value of each pixel in the real-time monitoring image;

[0102] The grayscale values ​​are used to form a grayscale monitoring image.

[0103] In detail, the grayscale monitoring image is Gaussian blurred using a Gaussian blur function to obtain a standard monitoring image. The Gaussian blur function formula is as follows:

[0104]

[0105] Wherein, G(x,y) represents the Gaussian function value at the position (x,y), σ represents the standard deviation of the Gaussian distribution in the grayscale monitoring image, and x and y represent the distance of each pixel in the grayscale monitoring image relative to the center of the Gaussian filter window within the Gaussian filter window.

[0106] In detail, performing edge detection on the standard monitoring image to obtain contour information includes:

[0107] Calculating the gradient intensity and gradient direction of the standard monitoring image;

[0108] Identifying a contour edge of the standard monitoring image according to the gradient intensity and the gradient direction;

[0109] Using a preset edge threshold interval to filter out strong edges that are greater than or equal to the upper limit of the edge threshold;

[0110] Screening out weak edges that are smaller than the upper edge threshold and larger than the lower edge threshold;

[0111] Contour information is generated according to the strong edge and the weak edge.

[0112] In detail, assuming an image of gradient intensity, the preset edge threshold interval is: the upper limit of the edge threshold is 100, and the lower limit of the edge threshold is 50. All pixels with gradient intensity greater than or equal to 100 (such as 130, 150, etc.) are marked as strong edges; all pixels with gradient intensity between 50 and 100 (such as 60, 80, etc.) are marked as weak edges; all pixels with gradient intensity less than 50 (such as 10, 30, etc.) are marked as non-edges.

[0113] Furthermore, the profile information includes: the construction workers, construction equipment and the activity range of the construction team. Through further analysis of the profile information, data related to the construction work can be extracted, such as the number of construction workers, working area, equipment status, etc.

[0114] Real-time monitoring images are collected using preset cameras to ensure visualization and timely feedback of the operation process. After converting the image into a grayscale image, Gaussian blur processing is used to reduce noise, improve image quality, and ensure the accuracy of subsequent analysis. Edge detection extracts important contour information in the image to help identify the dynamic activities of the work team. The construction operation monitoring data generated in combination with contour information provides an important basis for safety management, efficiency evaluation, and decision support, which helps to optimize the construction process, improve safety, and management efficiency.

[0115] S4. Identify the construction status and construction progress in the construction operation monitoring data to obtain the operation status of the construction operation team.

[0116] In an embodiment of the present invention, a preset YOLO model can be used to perform confidence analysis on the detection result that the construction status of the construction personnel is in an abnormal state, evaluate the status of the construction personnel, and decide whether to re-extract the construction status information of the construction personnel or issue a warning command based on the relationship with the confidence threshold.

[0117] In the embodiment of the present invention, the identifying of the construction status and construction progress in the construction operation monitoring data to obtain the operation status of the construction operation team includes:

[0118] Extracting the construction status and construction progress of the construction personnel preset in the construction operation monitoring data;

[0119] If the construction state is a preset abnormal state, coordinates of the location information of the construction personnel are marked to obtain personnel marking data;

[0120] Performing confidence analysis on the personnel labeling data to obtain the confidence of the abnormal state;

[0121] Screening out abnormal states whose confidence level is greater than or equal to a preset confidence level threshold;

[0122] Using a preset loudspeaker to issue a warning command to the construction personnel in the abnormal state;

[0123] If the construction status is a preset normal status, checking the completion status of the construction progress;

[0124] When the completion status of the construction progress is incomplete, returning to extract the construction status and construction progress of the construction personnel preset in the construction operation monitoring data;

[0125] When the completion status of the construction progress is completed, the operation status of the construction work team is obtained.

[0126] Furthermore, the operation status includes: location information, construction status and construction progress of the construction team during the construction process, and the operation status is transmitted to the remote terminal through a preset communication system.

[0127] By transmitting the location information, construction status, construction progress and other information of the construction work team during the construction process to the remote terminal in real time through a preset communication system, the efficiency and transparency of construction management can be significantly improved. The instant transmission of information can help project managers to keep abreast of the construction progress and quickly discover and solve potential problems.

[0128] In detail, the YOLO model is used to perform confidence analysis on the personnel annotation data. When the construction personnel are detected, a confidence score is provided for each detected construction personnel. The score reflects the confidence of the YOLO model in the construction status detection result. The confidence score is between 0 and 1. The higher the value, the more confident the YOLO model is in the construction status detection result. The annotation information includes: the bounding box coordinates of the construction personnel in the standard construction operation data, and the YOLO model outputs the confidence of the construction personnel.

[0129] By performing image recognition and processing on construction monitoring data, the accuracy of the data is ensured. By extracting the construction status and progress of construction workers, it is possible to timely identify whether there are abnormal conditions in the construction process. If the state of the construction workers is found to be abnormal, the confidence analysis using the YOLO model can further confirm the actual state of the construction workers, and take corresponding measures based on the analysis results, such as issuing warning commands to ensure construction safety and efficiency. This not only improves the real-time monitoring capabilities of the construction site, but also helps to promptly discover and solve potential problems, thereby effectively improving construction quality and safety.
