In addition, the integrated safety management system 10 (hereinafter referred to as 'system of the present invention') using worker status information at a construction site according to an embodiment of the present invention is implemented with a computing device to be mentioned in the description of FIG. 9 below. It can be.

When described with reference to the above drawings, the integrated safety management system 10 using worker status information at a construction site according to an embodiment of the present invention includes a safety scenario management unit 11 and a safety status as shown in FIG. 1. It is characterized by including an analysis unit 12 and a safety management information output unit 13.

The safety scenario management unit 11 sets safety rules for each time, space, and worker based on safety regulation information preset to correspond to the construction type and site information at the construction site and safety condition information input from the management terminal 30. It performs the function of creating and managing safety scenarios, which are information about.

The safety status analysis unit 12 uses image data captured from a plurality of image capture devices 40 placed at the construction site to recognize workers and construction site facilities through an object recognition algorithm, and recognizes the location of the recognized worker, It performs the function of generating safety status information by analyzing the worker's safety status using the worker's status, the status of the construction site equipment, the relationship information between the worker and the construction site equipment, and the safety scenario.

The safety management information output unit 13 collects the generated safety status information to generate safety status information for the entire construction site, and sends the generated safety status information and safety status information included in the safety status information to the management terminal 30. ) performs a function to output to the user interface.

Specifically, the safety scenario management unit 11 has a function of generating and managing information about safety scenarios automatically generated from information about the construction site, and the management terminal 30 while generating and managing information about safety scenarios. It performs the function of editing and managing information on safety scenarios according to the safety condition information input from.

In the present invention, information on safety scenarios will be understood to include, for example, information on response methods in the event of a safety accident, safety rules established for each of the multiple construction areas included in the construction site, etc. Safety rules can be set by time zone by dividing work time and non-work time, or by worker level (position). Specifically, safety rules refer to the control of access to the relevant construction area and the conditions for wearing safety equipment by workers present in the construction area. Safety condition information input from the management terminal 30 will also be understood as information according to the input of settings for the above safety rules.

That is, the safety scenario management unit 11 receives information on safety regulations and laws for the construction site from the administrative agency 60, for example, as shown in FIG. 2, and processes it based on this in the database 20. Information about the first safety scenario is created using information about the safety rules provided.

Regarding this, as shown in FIG. 2, when input for safety condition information is received from the management terminal 30, the previously generated safety scenario information is edited and stored, thereby converting and storing the latest version of the safety scenario information in real time. It will be done.

Information on the safety scenario that is initially created is generated using information on laws and regulations received from the database 20 and the administrative agency 60, as described above. At this time, information about safety rules at a general construction site can be generated regardless of information related to the construction site, but information about safety rules specialized for the construction site may also be necessary when creating a safety scenario for the construction site. .

For this purpose, in the present invention, the database 20 may manage information about the construction site, such as map information of the construction site, detailed information about the construction site, and information about the type of the construction site. That is, referring to FIG. 3, map information and detailed information may be used as site information 100.

Map information may include information on administrative districts, etc., detailed location of the construction site, information on areas such as buildings and roads near the construction site, and information on area. Detailed information on the construction site may include detailed information on facilities such as buildings constructed at the construction site, information on raw materials used, etc., and information on the construction period.

Information about the construction type 110 is information indicating the type of construction specialized for the construction site, information that can determine whether it is construction for a commercial building, residential building, etc., and information that can determine whether it is civil engineering work. This refers to information that can determine the type of construction.

Using this information, general safety scenarios (120) are information on safety equipment such as CCTV, safety equipment such as fire extinguishers, field equipment as equipment that workers must have, and portable safety equipment (hard hats, etc.) for each construction site. can be derived according to general safety regulations and safety regulations specialized for each construction site. At this time, in addition to the above-described information, the safety scenario 120 includes information on standard work hours, safety equipment required for each work area, and safety equipment required to be installed by workers who exist or may exist in the work area. You can.

Considering this, it would be natural that the safety condition information input by the management terminal 30 is also information that can be included in the safety rules as an editing input for the above-described safety scenario. Accordingly, the safety scenario management unit 11 provides regulatory information on the wearing of safety equipment for each worker, regulatory information and safety condition information related to the placement of safety equipment according to the type of construction and the size of the site, for each construction area included in the entire construction site. Safety scenarios can be created and managed using information about configurable safety conditions.

At this time, the safety scenario management unit 11 may receive input about safety condition information through the above-described user interface, etc. In other words, it is a menu included in the user interface output to the management terminal 30, and a menu for editing a safety scenario by inputting safety condition information can be called and used to input safety condition information through the user interface. There is.

In this case, the safety scenario management unit 11 may update the safety scenario by reflecting the setting input for the safety scenario from an authenticated construction site manager account accessed through the management terminal 30.

Specifically, as described above, when selecting the scenario edit menu 208 on the user interface screen 200 that can be output as in the example of FIG. 5, editing of the safety scenario is performed on the management terminal 30 as described above. As a possible menu, an interface screen 210 as shown in FIG. 6 may be output.

Referring to the screen 210 above, the manager calls the user interface using the management terminal through his/her account and displays the desired safety condition as an edit input for the safety scenario in the screen 210 output through the above-described process. You can enter information.

Specifically, through the floor selection menu 211, for example, as a drop-bar type menu, if the building to be constructed is a multi-story structure, the layout of each floor can be called and the safety scenario for this can be edited. It can be done.

In this case, the latest safety condition information previously set, that is, information about the safety scenario, can be displayed as current information on the output screen, and the safety scenario can be edited from this.

At this time, the administrator account can check the layout map 212. The layout map 212 is a screen on which a plurality of construction areas included in the construction site are output, and the administrator can use inputs such as dragging on the screen to ensure safety. You can select the construction area 213 you want to edit by entering safety condition information for the scenario. At this time, when selecting a construction area, the user can directly select one or more construction areas using the above-described drag input, etc., or when selecting a construction area at the construction site according to the division, coverage of field facilities, standard rules for risk, etc., one or more construction areas can be selected. The construction area can be selected automatically.

In the present invention, the construction area is a detailed unit area that makes up a construction site, and can be understood as a concept that includes areas that can be subdivided by construction site, construction type, and process, for example.

When the safety scenario management unit 11 receives a selection input for one or more construction areas 213, the safety scenario information for the corresponding construction area 213 can be output on each menu below, and for this, safety level information Setting input for the safety level information and the worker's access time set for each safety level information, the status of the worker for access, and the setting input for the safety equipment of the worker for access. After entering the settings for the access time, the status of the access worker, and the safety equipment of the access worker, you can select the save menu 214 to save the edited content of the safety scenario.

In the present invention, safety level information refers to grade information (G1, G2, etc.) about the status of personnel who can be deployed at the construction site, such as workers or managers who are judged to be able to enter the relevant construction area. At this time, the worker's access time (T1) can be set, which includes setting the access time for all workers, setting the grade of workers who can visit during a specific access time, and the equipment that the worker must wear during a specific access time. Settings for safety equipment (D1, D2, D3) can be set independently or in complex combination.

When a safety scenario is set using the screen of FIG. 6 where settings for such a safety scenario can be entered, monitoring of the construction site is immediately performed using the updated safety scenario. That is, the safety status analysis unit 12 uses the above-described safety scenario and information collected at the construction site to generate information on the safety status of the entire construction site or each worker.

Specifically, as described above, the location of the worker, the worker's condition, the state of the construction site equipment, the relationship information between the worker and the construction site equipment, and the safety scenario are taken into consideration in a complex manner.

At this time, the information about the worker's location is information set for the above-described video capture device 40, including information about the installation location of the video capture device 40 on the construction site, information about FOV (Field Of View), and video. It can be generated by processing information about the location of the operator object recognized in the data in the image data, and information about a specific floor can also be recognized from the installation location of the image capture device 40. Alternatively, as a result of performing a position measurement process using an external position measurement means and the worker's mobile terminal 60, information on the worker's specific level and detailed position may be determined.

The worker's status includes whether the worker is currently working or resting, the worker's body shape, the worker's body movement type determined through continuous frame analysis of the body shape, safety equipment installed by the worker, and information about the construction equipment the worker is using. It refers to the result of the object state determination algorithm determined based on the above information, and the above information can be derived as the determination result.

That is, as shown in FIG. 4, when the image capturing device 40 recognizes a worker from image data, information about the equipment (D1, D2) worn by the worker, etc. can be extracted through an object recognition algorithm. For example, a hard hat, a fluorescent jacket, etc. may be included in the equipment, and recognition results for the equipment (D1, D2) may be derived accordingly. Meanwhile, additionally, the worker's identification information, such as name, ID, position, etc., can be recognized and derived by using the code (I1) mounted or printed on the worker's equipment, etc., and through this, video data about the worker can be analyzed. Through this, it can be identified which worker it is.

The status of construction site facilities can be analyzed differently depending on whether they are non-electrical or electric. For example, in the case of non-electric equipment, the equipment 50 as shown in FIG. 4 includes recognition of the code I2 mounted or printed on the equipment 50, like the code I1 described above. Through this, the equipment itself can be identified, and information on the driving state due to the above-described form of the equipment 50 and changes in the shape of the equipment determined through continuous frame analysis are derived, thereby providing information on the safety status of the equipment 50. Information can be derived.

Meanwhile, in the case of electrical equipment, if it is determined what kind of equipment is recognized in the image data through recognition of the above-mentioned code (I2), information about the operating status of the equipment is directly transmitted to the management terminal through the communication function with the equipment. It is transmitted to (30), from which safety state information including information on normal driving state, etc. can be derived.

If identified in this way, as shown in the data set on the right side of Figure 4, the operator's location (P1), identification information (U1) and level information (G1) determined using the operator's ID, status information (working), and the operator's installed Information about safety equipment (D1, D2), etc. can be derived, and information about construction site facilities such as location (P1) and identification information (S1) can be derived. In this case, when the equipment is electric, information about the driving state can be transmitted from the equipment to the management terminal 30 through the direct communication function as described above.

Information on the relationship between workers and construction site facilities includes information on the availability of the above-mentioned electrical or non-electrical facilities determined through the worker's status, etc., and the distance between worker objects and facility objects determined through analysis of image data. Includes information on whether it is adjacent or not. Information on the safety status obtained from this can be used, for example, when the worker's position is judged to be closer than a preset threshold distance to unauthorized construction site equipment, or to construction site equipment to which access is prohibited when in operation. This may refer to information such as determining an unsafe state when it is determined that it is running and at the same time the worker object is determined to be closer than a preset threshold distance. Or, if the construction site equipment is safety equipment (e.g., lifeline or side scaffold escape prevention device, etc.) required for workers with a specific status during construction time, and the equipment is not adjacent to the worker, it is judged to be in an unsafe condition. The same information can also mean. Conversely, depending on the safety scenario, if an authorized worker wears safe equipment and operates approved construction site facilities, the safety condition may be judged as normal.

In other words, the safety status information is information for determining detailed safety derived as described above and the result of judgment as in the above-mentioned example considering this, such as whether the worker is currently in a safe state or the construction site equipment is operating normally, Finally, this may include information to determine whether the current safety status of the relevant construction area is normal.

In order to perform this function, the safety state analysis unit 12 may include a detailed configuration, for example, a worker identification unit, an installed equipment identification unit, and a first safety status determination unit.

As described above, the worker identification unit uses image data to identify the worker's condition and uses identification information (e.g. QR code or ID card) attached to the worker's body or equipment worn by the worker. It performs the function of identifying identification information.

The installed equipment identification unit performs the function of identifying information about the safety equipment installed by the worker using image data. For example, when recognizing a worker object, when a specific object is recognized by analyzing pixel data recognized from the worker's body parts, identification information for the object is derived as a result of applying an artificial intelligence neural network such as CNN or RNN to the object. Identification of safety equipment is performed using .

The first safety state determination unit applies the worker's identification information and information about the safety equipment installed by the worker to the safety level information set for each construction area and the safety scenario information to determine whether the worker can enter the construction area. and performs a function of generating safety status information for each worker, including information on whether the worker is wearing normal safety equipment in the construction area.

Meanwhile, as described above, the safety status related to the equipment can also be determined. In other words, the above-mentioned worker identification information uses image data to determine the worker's identification information using the identification information attached to the worker's body or the equipment installed by the worker, and the installed equipment identification uses image data to determine the worker's identification information. It performs the function of identifying information about the safety equipment installed by the worker by using video data to determine information about the safety equipment installed by the worker.

At this time, the safety state analysis unit 12 may include a second safety state determination unit, where the second safety state determination unit determines the distance relationship between the recognized location of the worker and the location of the construction site equipment, the identification information of the worker, and the worker. It performs a function of generating safety status information related to the worker's construction site equipment by using information about the safety equipment installed and information about the operating status of the construction site equipment received from the construction site equipment.

When the safety management information output unit 13 collects this safety status information, the safety management information output unit 13 synthesizes the entire construction area and provides the detailed information described above as a total of safety status information for the entire construction site. And KEPCO status information as an integrated concept of whether each construction area is in a safe state is generated, and as described later, the management terminal 30 is configured to implement and output the overall safety status information and the safety status information included therein on the user interface. takes control.

An example of the above-described user interface is shown in FIG. 5. Referring to FIG. 5, as can be seen through the user interface screen 200, the user interface includes a three-dimensional construction site map that organizes the construction site by floor, and the construction site. On the site map, a worker icon is displayed by mapping the position of the worker determined based on the size and location information on the video data of the worker recognized in the video data, safety status information indicating the safety status of the worker, and construction site equipment. Information on the operating status of construction site equipment and historical data on safety status information received from a three-dimensional construction site map that organizes the construction site by floor, on the video data of workers recognized from the video data on the construction site map. A worker icon in which the position of the worker determined based on size and location information is mapped and displayed, safety status information indicating the safety status of the worker, information on the operating status of construction site equipment and safety status received from the construction site equipment. History data about information, etc. may be output.

Accordingly, the construction site map 201 data and the worker icon 203 matching it can be displayed on the screen 200 in response to the above-mentioned information, and the safety status information indicating the worker's safety status is expressed by the color of the icon, etc. can be displayed. That is, it can be understood that the worker icon displayed in bold in FIG. 5 indicates a worker whose safety condition is judged to be dangerous.

At this time, when selecting the worker icon displayed in bold, for example, in order to check detailed information on the safety status of each worker and enable the worker to take safety measures, a sub-interface such as screen 220 shown in FIG. 7 is displayed. may be output to the management terminal 30.

For example, information about the location 222 on the map 221 as information about the selected worker (U1), the event effect 223 indicating the current dangerous state, and the current detailed location (L2, SEC2) are checked. Information, information about the worker's grade (G3), that is, level information, and detailed information about the currently recognized safety status information, check information about the equipment (D1, D2) worn by the worker, and warn through the menu 224. A message, etc. is transmitted or preset warning notification information is transmitted, so that this can be confirmed on the worker terminal 60.

Information about the specific construction area 204 is information that displays special matters in the safety scenario, for example, a case where entry is currently impossible or an event that displays an area where a safety scenario is set according to the status level of the worker. It can be understood as

The history view menu 205 is a menu that allows you to recall history data as described above, and the send message menu 206 sends a message about safety to a specific worker, a specific level of workers, or all workers, or to a construction site. This is a menu that allows you to enter a message related to safety or work to be transmitted through an audio output means such as a speaker or a visual output means such as a display device.
