Figure 1 is a diagram showing a safety management system 10 through image analysis according to an embodiment of the present invention, and Figure 2 is a diagram showing a safety management system 10 recognized by the dangerous situation recognition unit 100 provided in the system 10 of Figure 1. This is a diagram illustrating dangerous situations.

Referring to FIG. 1, the safety management system 10 according to an embodiment of the present invention may include a hazardous situation recognition unit 100, a risk determination unit 200, and an output unit 300.

The safety management system 10 may be implemented in the form of a server. Specifically, the safety management system 10 may include an AI model. The AI model may be learned based on unsupervised learning, but is not limited to this, and may also be learned based on supervised learning or semi-persistent learning. there is.

Additionally, an AI model may consist of one or more neural network layers, and each neural network may include one or more weights. AI models can perform learning/inference by performing operations between one or more weights and input data. As an example, the AI model can perform image analysis based on Deep Neural Network (DNN), Convolution Neural Network (CNN), etc.

The dangerous situation recognition unit 100 may be configured to collect image information about at least one dangerous situation from a plurality of CCTVs arranged in a plurality of areas of the work site.

As shown in FIG. 2, the risk determination unit 200 provides first information on whether the worker complies with safety rules recognized from the image information collected through the hazardous situation recognition unit 100, and the normal arrangement/appearance of equipment at the work site. Determine the risk of a hazardous situation by considering at least one of the second information about whether it is normal, third information about the positional relationship between dangerous substances at the work site and the worker, and fourth information about whether a disaster situation occurs at the work site. It can be configured to do so.

That is, in an embodiment of the present invention, the risk determination unit 200 does not simply determine the risk by considering only the appearance of the worker and the work site in the image collected through the risk situation recognition unit 100, but also determines the risk by considering the worker's behavior. , the degree of risk of a hazardous situation can be determined by comprehensively considering the locational relationship between the worker and the work site, the disaster occurrence situation, etc.

The output unit 300 is a site manager terminal 20 that, when the risk of the dangerous situation determined by the risk determination unit 200 is above a certain standard, the video information about the dangerous situation is used by the site manager who manages the work site. and may be configured to provide the information to the main manager terminal 30 used by the main manager who controls the field manager.

At this time, the field manager terminal 20 may be a mobile device or a PC used by the field manager. And, the main manager terminal 30 may be a mobile device or a PC used by the main manager.

According to this implementation configuration of the present invention, when determining the risk of a dangerous situation above a certain standard by comprehensively considering the worker's behavior, the location relationship between the worker and the work site, and the disaster occurrence situation, the risk situation is notified to the site manager and the main manager. Therefore, it has the advantage of being able to respond more efficiently to disasters occurring at industrial sites.

Referring again to FIG. 2, the first information may include information on whether the worker is wearing safety equipment. As an example, the first information may include information about whether the worker wore a safety helmet, safety clothing, safety shoes, etc.

The second information may include information about the degree to which the equipment at the work site is tilted with respect to the ground and information about whether the external appearance of the equipment is damaged. As an example, equipment on a job site may include storage tanks, transportation pipes, manufacturing machinery, storage warehouses, etc.

The third information may include information about the vertical distance between hazardous materials and workers at the work site and the horizontal distance between hazardous materials and workers at the work site. As an example, hazardous materials may include toxic substances, tank trucks, construction machinery/equipment, oil tanks, etc.

The fourth information includes information on whether a fire occurs at the work site, information on whether toxic gases/toxic substances leak at the work site, information on whether there is a water leak at the work site, and information on whether equipment at the work site explodes. May contain information.

3 to 5 are diagrams showing an example of how the risk determination unit 200 provided in the system 10 of FIG. 1 determines the risk of a dangerous situation.

Referring to Figure 3, the risk determination unit 200, Depending on whether high-risk materials are placed at the work site, when determining the risk of a hazardous situation, the first and second information are considered more preferential than the third and fourth information, or the third and fourth information are considered as first information. and may be configured to determine the risk of a risky situation by assigning a first weight that is considered more preferential than the second information.

Specifically, when the risk determination unit 200 determines that there are high-risk materials such as flammable materials or oil tanks at the work site, the third information and fourth information are used rather than the first and second information when determining the risk of a hazardous situation. It may be configured to determine the risk of a risky situation by assigning a first weight that considers more preferentially. This means that when there is a high-risk material at the work site, the third information about the positional relationship between the dangerous material at the work site and the worker and the fourth information about whether a disaster situation occurs at the work site are used by the worker in determining the risk of the hazardous situation. This is because it acts as a bigger factor than the first information about whether the safety rules are followed and the second information about whether the equipment at the work site is normally arranged/appeared normal.

Alternatively, when the risk determination unit 200 determines that there are no high-risk materials such as flammable materials or oil tanks at the work site, the first information and the second information are ranked higher than the third information and the fourth information when determining the risk of a hazardous situation. It may be configured to determine the risk of a risky situation by assigning a first weight that is considered more preferential. This means that, in cases where there are no high-risk materials at the work site, the first information on whether the worker complies with the safety rules and the second information on whether the equipment is normally placed/appeared at the work site are used at the work site in determining the risk of a hazardous situation. This is because it acts as a bigger factor than the third information about the positional relationship between hazardous materials and workers and the fourth information about whether a disaster situation occurs at the work site.

Referring to FIG. 4, depending on the industrial field to which the work site belongs, the risk determination unit 200 considers the second to fourth information more preferentially than the first information when determining the risk of a hazardous situation, or considers the first information more preferentially than the first information. It may be configured to determine the risk of a dangerous situation by assigning a second weight that considers it more preferentially than the second to fourth information.

Specifically, when the risk determination unit 200 determines that the work site belongs to an equipment-intensive or technology-intensive industrial field (e.g., construction, oil refining, plants, etc.) that requires a large number of facilities, when determining the risk of a hazardous situation, It may be configured to determine the risk of a dangerous situation by assigning a second weight that considers the second to fourth information more preferentially than the first information. This is, if the work site belongs to an equipment-intensive or technology-intensive industrial field that requires multiple facilities, second information on whether the equipment is normally placed/appeared at the work site, and the positional relationship between hazardous materials and workers at the work site. This is because the third information about and the fourth information about whether a disaster situation occurs at the work site acts as a greater factor than the first information about whether the worker complies with safety rules in determining the risk of a hazardous situation.

Alternatively, if the risk determination unit 200 determines that the work site belongs to an industrial field that does not require many facilities (e.g., general service industry, professional service industry, agriculture, etc.) , the second information to the second information is used when determining the risk of a hazardous situation. It may be configured to determine the risk of a risky situation by assigning a second weight that considers the first information more preferentially than the 4 information. This means that if the work site belongs to an industrial field that does not require many facilities, the first information about whether the worker complies with safety rules is used as a criterion for determining the risk of a hazardous situation and whether the equipment at the work site is normally placed/appears normal. This is because it acts as a bigger factor than the second information, the third information about the positional relationship between hazardous materials and workers at the work site, and the fourth information about whether a disaster situation occurs at the work site.

Referring to FIG. 5, the risk determination unit 200 considers the second to fourth information more preferentially than the first information when determining the risk of a hazardous situation, depending on the density of workers compared to the total area of the work site. It may be configured to determine the risk of a dangerous situation by assigning a third weight that considers the first information more preferentially than the second to fourth information.

Specifically, when the risk determination unit 200 determines that the density of workers compared to the total area of the work site is above a certain standard, the risk determination unit 200 considers the second to fourth information more preferentially than the first information when determining the risk of a hazardous situation. It may be configured to determine the risk of a risky situation by assigning a third weight. This means that when the density of workers is high compared to the total area of the work site, the second information on whether the equipment is normally arranged/appeared at the work site, the third information about the positional relationship between hazardous materials and workers at the work site, and the This is because the fourth information about whether a disaster situation has occurred acts as a bigger factor in determining the risk of a dangerous situation than the first information about whether the worker complies with safety rules.

Alternatively, when the risk determination unit 200 determines that the density of workers compared to the total area of the work site is below a certain standard, the risk determination unit 200 considers the first information more preferentially than the second to fourth information when determining the risk of a hazardous situation. 3 It can be configured to determine the risk of a risky situation by assigning weight. This means that when the density of workers is low compared to the total area of the work site, the first information about whether workers comply with safety rules is used in determining the risk of a hazardous situation, the second information about whether the equipment at the work site is normally arranged/appears normal, This is because it acts as a bigger factor than the third information about the positional relationship between hazardous materials and workers at the work site and the fourth information about whether a disaster situation occurs at the work site.

In one embodiment, the risk determination unit 200 may be configured to set the first weight higher than the second weight and the third weight when determining the risk of a risky situation.

That is, the risk determination unit 200 sets the first weight that considers whether or not high-risk materials are placed at the work site among the weight items when determining the risk of the above-mentioned dangerous situation, and the first weight that considers the industrial field to which the work site belongs. 2 It can be considered a more important factor than the third weight, which considers the density of workers compared to the total area of the work site.

This is because if there are high-risk materials such as flammable materials or oil tanks at the work site, the possibility of a large-scale disaster such as a fire occurring at the work site when an abnormal situation occurs can be much greater than if there are no high-risk materials, and the risk judgment department ( Taking this into account, 200) may set the first weight to be higher than the second and third weights when determining the risk of a dangerous situation.

In one embodiment, when determining the risk of a hazardous situation by considering the fourth information about whether a disaster situation occurs at the work site, the risk determination unit 200 includes information about the current weather situation in the area where the work site is located. and information on the geographical characteristics of the area where the work site is located, and may be configured to adjust the risk of the hazardous situation.

That is, when the risk determination unit 200 determines the risk of a hazardous situation by considering the fourth information about whether a disaster situation has occurred at the work site, environmental information (information about the weather situation) of the area where the work site is located , information on geographical characteristics) can be additionally considered.

For example, information about current weather conditions in the area where the work site is located, such as whether it is currently raining, snowing, hailing, foggy, or experiencing typhoons/strong winds in the area where the work site is located. It may include information about the weather and whether the area where the work site is located is clear. This is to consider these factors when determining the risk of a hazardous situation, as the level of risk varies even in the same disaster situation (e.g. fire outbreak, etc.) depending on the current weather conditions in the area where the work site is located. By way of example, if the weather conditions in the area where the work site is located are adverse (e.g., strong wind/typhoon occurrence, etc.), the risk determination unit 200 determines that the disaster situation will deteriorate more quickly (e.g., fire, etc. due to strong winds). Considering that it can spread faster, it can be configured to set the risk of a dangerous situation higher. Here, information about the current weather situation in the area where the work site is located may be transmitted to the risk determination unit 200 from a separate weather information information server (not shown).

Additionally, information about the geographical characteristics of the area where the work site is located, It may include information on whether the area is open, forested, hilly, or flat. This is because the level of risk varies even in the same disaster situation (e.g. water leakage due to water tank damage, etc.) depending on the geographical characteristics of the area where the work site is located, so these factors are taken into consideration when determining the risk of a hazardous situation. Illustratively, the risk determination unit 200 determines that if the geographical characteristics of the area where the work site is located are adverse conditions (e.g., hilly areas, etc.), the disaster situation deteriorates more quickly (e.g., from highlands to lowlands along the slope of a hilly area). Considering that leaked water may quickly flow in, the risk of a hazardous situation may be set higher. Here, information about the geographical characteristics of the area where the work site is located may be transmitted to the risk determination unit 200 from a separate geographical information information server (not shown).

In this way, the level of risk of a hazardous situation can be determined by additionally considering environmental information (information about weather conditions, information about geographical characteristics) of the area where the work site is located, so it is possible to more efficiently prevent disasters at industrial sites. You can deal with it.

FIG. 6 is a diagram illustrating an example in which the output unit 300 provided in the system 10 of FIG. 1 de-identifies a worker from high-risk image information.

Referring to FIG. 6, the dangerous situation recognition unit 100 may be configured to collect image information from each of a plurality of CCTVs arranged in a plurality of areas of the work site.

In addition, the output unit 300 selectively outputs only the image information determined to have a risk level above a certain standard by the risk determination unit 200 among the image information to the field manager terminal 20 and the main manager terminal 30. ) can be configured to provide.

In other words, the output unit 300 does not notify the site manager and main manager of all video information at the work site, but only video information judged to have a high risk, thereby ensuring safety due to unnecessary video information transmission. Deterioration in management efficiency can be minimized.

More specifically, the output unit 300 selects image information determined to have a risk higher than a certain standard by the risk determination unit 200 among each image information, The image may be configured to process the image so that at least part of the worker's appearance is non-identifiable. As an example, the output unit 300 can process the image so that at least a part of the worker's appearance is non-identified through an AI model (e.g., using a CNN algorithm, etc.) from image information determined to have a risk level above a certain standard. there is.

That is, when the output unit 300 notifies the field manager and the main manager of video information with a high risk, at least part of the worker's appearance is de-identified to protect the privacy of the worker shown in the video information. can do.

As an example, the output unit 300 may perform blur processing so that the worker's face is not exposed in image information determined to have a risk level above a certain standard, as in option 1 of FIG. 6 . Alternatively, the output unit 300 may process the overall appearance of the worker in the form of a 3D computer image from image information determined to have a risk level above a certain standard, as in option 2 of FIG. 6.

According to this implementation configuration, there is an advantage in that it can reliably protect the privacy of workers while minimizing the decrease in safety management efficiency due to unnecessary transmission of image information.

The degree of risk of a hazardous situation is determined by considering at least one of the third information about the positional relationship between the hazardous material and the worker and the fourth information about whether a disaster situation occurs at the work site.

In step S3, the output unit 300, when the risk of the determined dangerous situation is greater than a certain standard, sends video information about the dangerous situation to the site manager terminal 20 and the site manager for use by the site manager who manages the work site. It is provided to the main manager terminal 30 used by the controlling main manager.

Meanwhile, the safety management method through image analysis can be implemented in the form of a computer program stored in a computer-readable storage medium. That is, the computer program may include instructions for implementing a safety management method through image analysis, and the instructions of the computer program may be stored in a computer-readable storage medium.
