Description

Technical Field

[0001] The present invention relates to the technical field of work safety, and more specifically, to a safety warning method and system for the entry and exit of construction site vehicles. Background Art

[0002] Currently, the construction site refers to the construction site occupied with approval for construction activities such as building construction, civil engineering, equipment installation, pipeline laying, etc. of industrial and civil projects, as well as the place for humans to carry out work safety, civilized work, and construction, including all areas on land, at sea, and in the air where construction work can be carried out.

[0003] However, due to the small area of the construction site, there are many engineering vehicles, the driving lanes are narrow, there are blind spots in the vehicle entrance area, and the driver's field of vision is limited. Due to the limited site, the entrance of the community is adjacent to both sides of the entrance, and the social pedestrian passage is located at the construction site entrance. The safety awareness of social personnel is weak. Muck transport vehicles, material transport vehicles, and other engineering vehicles are very likely to cause traffic accidents, resulting in losses to the company and the project. While warning, it is also necessary to ensure that relevant vehicles perform relevant engineering operations on site. However, there is a lack of a relevant hierarchical warning system in the prior art.

[0004] Therefore, how to provide a safety warning method for the entry and exit of construction site vehicles that can solve the above problems is an urgent problem for those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a safety warning method and system for the entry and exit of construction site vehicles.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A safety warning method for the entry and exit of construction site vehicles includes the following steps: Obtain the site monitoring data and environmental monitoring data of the construction site; Identify the site monitoring data to obtain the vehicle information contained in the site monitoring data; Match the vehicle information with the vehicle preset information database respectively to obtain the corresponding vehicle information matching results; Determine whether there are any illegal behaviors according to the vehicle information matching results. When there are, give an alarm prompt and drive away.

[0007] Preferably, the specific processing process of determining whether there are any illegal behaviors according to the vehicle information matching results includes: Divide the construction area according to the importance level to obtain the result of the construction function division area, and match the vehicle information with the vehicle preset information database; When the matching is successful, construct and train a trajectory recognition model, and input the environmental monitoring data and vehicle information into the trajectory recognition model for processing to obtain the corresponding trajectory recognition result; Determine whether there is any violation according to the trajectory recognition result.

[0008] Preferably, the specific processing process of determining whether there is any violation according to the trajectory recognition result includes: Extract the corresponding position recognition result from the trajectory recognition result; According to the result of the construction function division area, judge whether the position recognition result is located in a dangerous area. If it is in a dangerous area, directly drive it away; When it is not in a dangerous area and does not reach the first warning drive-away threshold, continue to monitor, and at the same time set up a safety warning projection system for prompting.

[0009] Preferably, the specific processing process of continuing to monitor when it is not in a dangerous area and does not reach the first warning drive-away threshold includes: When it is not located in a dangerous area and reaches the first warning drive-away threshold, construct a risk assessment model, and input the trajectory recognition result into the risk assessment model for evaluation to obtain the corresponding risk assessment result; Determine whether to notify the staff for handling according to the risk assessment result.

[0010] Preferably, the specific processing process of determining whether to drive away according to the risk assessment result further includes: When the risk assessment result shows that there is no need to drive away, continuously monitor the vehicle and notify the staff for handling when it reaches the second warning drive-away threshold.

[0011] Preferably, the specific processing process of determining whether there is any violation according to the vehicle information matching result further includes: Drive away the vehicles that fail to pass the matching.

[0012] The present invention also provides a construction site safety warning system, including: An acquisition module for acquiring the site monitoring data and environmental monitoring data of the construction site; An identification module for identifying the site monitoring data to obtain the vehicle information and personnel behavior information contained in the site monitoring data; A matching module for respectively matching the vehicle information and personnel information with the vehicle preset information database and the employee preset information database to obtain the corresponding vehicle information matching result and personnel information matching result; An early warning module, which is used to determine whether there are any violations according to the vehicle information matching result and the person information matching result, and give an alarm prompt when there are violations.

[0013] As can be seen from the above technical solutions, compared with the prior art, the present invention discloses a method and system for early warning of the safety of construction site vehicle access, having the following beneficial effects: 1. By obtaining the site monitoring data and environmental monitoring data of the construction site, the present invention provides a rich and comprehensive information basis for subsequent safety early warning, which helps to more accurately analyze the safety status of vehicle access to the construction site.

[0014] 2. By identifying the site monitoring data, the present invention can accurately extract vehicle information, providing key data for subsequent matching with the vehicle preset information database, making the management of vehicles entering and leaving the construction site more refined.

[0015] 3. By matching the vehicle information with the vehicle preset information database and analyzing the vehicle trajectory in combination with the trajectory recognition model, the present invention can more accurately determine whether there are any violations of the vehicle. This method based on database matching and trajectory recognition improves the efficiency and accuracy of judging violations, and avoids the errors and delays of manual judgment.

[0016] 4. By dividing the construction area according to the importance level and judging whether the vehicle is located in the dangerous area according to the trajectory recognition result, the present invention can timely discover potential safety hazards. Vehicles entering the dangerous area can be directly driven away, effectively preventing the occurrence of safety accidents.

[0017] 5. By introducing the first early warning and driving-away threshold and the second early warning and driving-away threshold, the present invention can dynamically evaluate the risk according to the vehicle behavior and take corresponding measures according to different risk levels. This hierarchical early warning mechanism can not only timely and effectively respond to serious violations, but also avoid excessive interference with normal construction activities, improving the flexibility and pertinence of safety early warning.

[0018] 6. By constructing a risk assessment model to evaluate the trajectory recognition result and determining whether to notify the staff for handling according to the risk assessment result, the present invention realizes the intelligent decision-making of safety early warning. This processing method based on risk assessment can more scientifically judge the safety status of the vehicle and improve the effect of safety management.

[0019] 7. When no violation is found or the relevant multiple eviction thresholds are not reached, the system can continuously monitor the vehicle to ensure real-time control of the safety status of the vehicles entering and leaving the construction site. This continuous monitoring mechanism helps to detect potential safety problems in a timely manner and prevent sudden safety accidents. When the vehicle is not in a dangerous area and does not reach the first warning eviction threshold, a safety warning projection system is set up for prompt, enhancing the safety warning effect at the construction site and improving the safety awareness of vehicle drivers.
