Description

How to manage safety status information {METHOD FOR MANAGING SAFTY CONDITION INFORMATION}

Embodiments of the present invention relate to a method for managing safety state information.

In general, safety inspection of facilities is divided into regular inspection, detailed inspection and emergency inspection. Inspection consists of items such as monitoring, exterior inspection, and structural review, and based on the inspection results, it is decided whether repair, reinforcement, dismantling, demolition, or restoration of function.

Therefore, safety diagnosis and maintenance inspection are very important because it is necessary to quickly find defects or inherent danger factors in the facility and take measures to prevent the risk of collapse or accidents. In particular, technology that facilitates the storage of inspection records and enables real-time correction, supplementation, and comparative analysis at the inspection site to easily, quickly and accurately judge the progress of risk factors and the appropriateness of repair and reinforcement. need.

In the past, the related information required for facility maintenance was generated by personnel passing through many relevant parties, and although the amount of information that needs to be collected is vast, the process of generating, collecting, and delivering information is not yet efficient. Not only was the confirmation not prompt, but it often did not reflect the current status.

In the past, the main method for safety management of facilities was regular visual inspections of related persons. In such an exterior survey, the main focus was to check the damage and appearance of the facility, and the overall behavioral characteristics of the structure could not be grasped.

Moreover, interest in the facility safety management system is getting more attention in order to improve unscientific methods in facility maintenance and efficient facility maintenance.

In addition, the state of the facility may change from moment to moment as a disaster such as a fire or earthquake occurs, and if it is difficult to predict it, it is difficult to cope with the disaster when it occurs, so it is necessary to develop a predictive technology for this.

Hereinafter, specific embodiments will be described with reference to the drawings. The following detailed description is provided to provide a comprehensive understanding of the methods, apparatus, and/or systems described herein. However, this is merely an example and the disclosed embodiments are not limited thereto.

In describing the embodiments, if it is determined that a detailed description of a related known technology may unnecessarily obscure the gist of the disclosed embodiments, the detailed description thereof will be omitted. And, the terms to be described later are terms defined in consideration of functions in the disclosed embodiments, which may vary according to intentions or customs of users and operators. Therefore, the definition should be made based on the content throughout this specification. The terminology used in the detailed description is for the purpose of describing the embodiments only, and should in no way be limiting. Unless explicitly used otherwise, expressions in the singular include the meaning of the plural. In this description, expressions such as “comprising” or “comprising” are intended to indicate certain features, numbers, steps, acts, elements, some or a combination thereof, one or more other than those described. It should not be construed to exclude the presence or possibility of other features, numbers, steps, acts, elements, or any part or combination thereof.

1 is a flowchart illustrating a method for managing safety state information according to an embodiment of the present invention.

Referring to FIG. 1, the safety state information management method according to an embodiment of the present invention generates the safety state information of a building through a system by minimizing the manpower and changes the safety state that is changed by the occurrence of a disaster risk. As a method, when a disaster risk occurs, it may be to apply a change in the safety state inside the building and facility so that it can be utilized in various disaster situations.

To this end, the safety state information management method for a building may be performed through the following steps.

First, it is possible to acquire the building information of the building SHP data for the building for generating the safety state information (S10). The SHP data may be spatial data in Korea provided through the national spatial information portal. The data is publicly available through open markets, so it is easy to access, and since it is provided by the state, reliability can be guaranteed. Since information on all buildings in Korea is covered through SHP data, in an embodiment of the present invention, information on buildings can be secured by using SHP data.

Lightweight safety state information can be derived from the secured building information through the lightweight safety state information model (S20). The safety state information lightweight model may be a model for generating safety state information from information obtainable through building information. The safety status information lightweight model can generate wide-area safety status information without a separate on-site investigation or additional information. Safety status information The safety status information (lightweight safety status information) generated through the lightweight model may be safety status information of a building unit. The building information may include information (first sub-information) such as the type of business, building structure, number of floors, and year of construction of the corresponding building.

When the lightweight safety state information is generated, the compact safety state information can be derived through the compact safety state information compact model by adding the manual survey information of the corresponding building to the lightweight safety state information for the corresponding building (S30). In the safety state information compact model, in addition to the previous building information, information (second sub-information) such as firefighting equipment facilities for each floor in the corresponding building, fire risk, and fire response status may be included.

The safety status information compact model can generate compact safety status information by quickly acquiring additional information through a rapid on-site investigation within a building in a set manual and reflecting it. However, since this is not a detailed investigation of the safety status of the building, it is a quick investigation and reflection of the items in the manual set in advance. There may be some limitations.

Precise safety status information can be derived through the safety status information precision model by adding the detailed investigation information for each zone of the building to the lightweight safety status information (S40). Precise safety status information can generate safety status information for each specific zone through precise on-site investigation by overcoming the limitations of compact safety status information (it cannot indicate the status of each detailed zone, and the precision is low).

2 is a flowchart illustrating detailed steps of the step of acquiring building information from building SHP data for a building.

Referring to FIG. 2 , as a method of acquiring building information, (1) a method in which a building is designated through input of an address of the building, (2) a method in which a building is designated through a map app (google map, etc.) for a terminal such as a mobile phone , (3) A method of designating a building through GPS information, gyro sensor information, and acceleration sensor information that can be obtained while photographing a building with a portable terminal can be selected.

First, in the case of the method of entering the address of the building, first, the address may be input through a mobile phone or the like (S11). In principle, the address input is determined by the street name address (S12), but when the old address is the lot number address (S11-1), the street name address may be changed. When the street name address is determined, the corresponding building SHP data can be linked (S18), and the building SHP data can be linked through the national spatial information portal.

Second, in the case of using the terminal map app, first, when the user designates a building on the map through a map app (google map, etc.) on a mobile phone (S13), through the x, y coordinates of the map screen (S13-1) ) can be mapped to the longitude and latitude coordinates of the building (S17). The street name address is determined through the longitude and latitude coordinates, and the building SHP data can be linked through this (S18, S19). Linking the building SHP data in the national spatial information portal through the street name address may be the same as the previous method.

Third, the case of photographing a building will be described with reference to FIGS. 3 and 4 together with FIG. 2 . FIG. 3 is a diagram illustrating a portable terminal and a sensor inserted therein, and FIG. 4 is a diagram illustrating designation of a building through a camera photographing of the portable terminal. First, a building can be photographed through a portable terminal having a built-in GPS, a gyro sensor, and an acceleration sensor (S14). For example, a GPS, an acceleration sensor, and a gyro sensor 100 may be included in a portable terminal for photographing. Through this, a photographing position and an xyz direction of the corresponding portable terminal 200 can be set (S15). Here, the photographing direction of the camera may be the +z direction in FIG. 3( b ). As described above, when the photographing direction of the camera is determined and the position of the portable terminal including the camera is determined through GPS, the position and photographing direction of the camera 10 in the portable terminal may be determined as shown in FIG. 4 . Then, with the photographing point of the camera 10 as a vertex, the sector 20 corresponding to an angle of about 1 to 5° left and right and a radius of 30 to 70 m in the direction of taking a picture can be created. A building located within the sectoral shape 20 can be selected from the building SHP data of the national spatial information portal. If there is one selected building, location information of the corresponding building may be acquired, and if there are multiple selected buildings, location information of the building 50a closest to the shooting point may be acquired (S16). When the building 50a from which the location information is obtained is designated, the longitude and latitude coordinates of the building are mapped (S17), and the building SHP data of the corresponding building can be linked (S18, S19).

5 is a diagram showing units applied to each safety state information model.

Referring to FIG. 5, as described above, in the case of the lightweight model of the safety state information, the safety state information is generated and applied only to the building unit, and in the case of the safety state information compact model, the safety state information is generated and applied up to the floor unit of the building. can In the case of the safety status information precision model, safety status information can be created and applied to the most detailed building area unit.

6 is a diagram illustrating information elements applied to each safety state information model.

Referring to FIG. 6 , numbers 1 to 4 among a total of 13 information elements may be applied to all safety state information models. The corresponding information may be referred to as first sub-information. Nos. 5 to 13 are not applied to the lightweight model of the safety status information, but can be applied to the compact model of the safety status information and the precise model of the safety status information. The corresponding information may be referred to as second sub-information. In other words, since the safety state information lightweight model generates safety state information with only the first sub-information (information that can be obtained from SHP data on buildings), it is possible to obtain the safety state information most quickly with little need for manpower. However, in order to obtain more detailed areas and precise information, the compact model of the safety state information and the precise model of the safety state information can be used.

7 is a table showing the level of risk of each industry type of building.

Referring to FIG. 7 , the industry risk level for each type of building may be information included in the first sub-information. The risk level for each industry can be created as follows.

First, it is possible to calculate the life risk index for each industry. In Equation 1 below, the average number of deaths and injuries per year can represent the number of deaths and injuries that actually occur on an average for each type of building industry.

[Equation 1]

In addition, there is a risk to property as well as a risk to human life, and the ratio of human risk to property risk can be applied as 10:3. Through this, it is possible to calculate the degree of risk for each industry as shown in FIG. 7 .

8 is a table showing the degree of risk for the building structure, the number of building floors, and the degree of deterioration among elements related to the building characteristics.

Referring to FIG. 8 , the building characteristic may be information included in the first sub-information. Building characteristics may include risk information on the building structure, the number of building floors, and the degree of deterioration.

As shown in FIG. 8 , the building structure may determine the level of risk according to the material entering the main structural part of the building. And the number of building floors may determine the risk level according to the number and height of the building. In addition, the level of risk may be determined according to the age of the building. The peculiarity is that the higher the number of floors, the higher the risk level, but the higher the level of the underground facility, the greater the risk. Considering this, it may be that the level of risk rises somewhat.

9 is a table showing the degree of risk for firefighting equipment and facilities.

Referring to FIG. 9 , the degree of risk for fire-fighting equipment and facilities may include a degree of risk for automatic fire-fighting equipment installation, automatic fire detection equipment installation, and smoke control equipment installation. The level of risk for firefighting equipment and facilities may be information included in the second sub-information.

10 is a table showing the degree of risk for fire hazard.

Referring to FIG. 10 , the degree of risk for fire risk may include a degree of risk for inflammables storage/management status, hazardous material management status, separation distance from adjacent buildings, and external wall structure. The level of risk for fire risk may be information included in the second sub-information.

11 is a table showing the degree of risk for the fire response state.

Referring to FIG. 11 , the level of risk for the fire response state may include the number of evacuation exits, installation of a regular manager and fire alarm, and an access road for access to the public fire brigade and risk level for the state. The level of risk for the fire response state may be information included in the second sub-information.

12 is a table showing the criteria for calculating the fire risk evaluation score in the safety state information precision model.

Referring to FIG. 12 , the fire risk evaluation score can be obtained in a way that a final score can be calculated by weighting the level score for each element. The expression is as follows.

[Equation 2]

And, the final safety evaluation score for determining the compact safety state information or the precise safety state information may be 100 minus the fire risk evaluation score. That is, the lower the fire risk evaluation score, the higher the final safety evaluation score may appear.

13 is a diagram illustrating a manual for determining first sub-information and second sub-information in the safety state information compact model.

14 is a flowchart illustrating a method of changing light weight safety state information when a fire occurs according to an embodiment of the present invention.

Referring to FIG. 14 , when a fire occurs at a specific point, a lightweight safety state information model may be applied to change the weight reduction safety state information (S50). When a fire is detected (S51), the fire impact range may be calculated in consideration of the wind direction and wind speed of the corresponding point at the time point, and this may be applied to the time-varying safety state information (S52). In order to know the wind direction and speed, it is possible to link real-time forecast data from the Korea Meteorological Administration.

FIG. 15 is a diagram illustrating setting the fire impact range 350 when a fire occurs at a specific point 300 , and FIG. 16 is a diagram illustrating a plurality of zones constituting the fire impact range.

Referring to FIG. 15 , when a fire occurs in a building at a specific point 300 , as described above, the fire impact range 350 may be set in consideration of the corresponding point in time and the wind direction and wind speed at the corresponding point. As shown in FIG. 16( a ), the fire impact range 350 may be set within an area within an angle of 45° left and right based on the wind direction with the point where the fire occurred as a vertex. For example, if the wind speed is 10 m/s, the fire impact range 350 is 100 m as a whole, and within I zone (350a), II zone (350b), III zone (350c) and outside III zone (350d). can be set. The setting of zones for each street in this way may be to change the safety state information differently for buildings corresponding to each of the zones. When the wind speed is changed, the total distance of the fire impact range 350 may be different. For example, when the wind speed is less than 10 m/s, the fire impact range 350 is set to 80 m, the I zone is 20 m, the II zone is 40 m, the III zone is 60 m, and the outside of the III zone can be up to 80 m. And, when the wind speed is 10 m/s or more and less than 20 m/s, the fire impact range 350 is 100 m as described above, and when the wind speed is 20 m/s or more and less than 30 m/s, it is 125 m. can be done at 150 m.

In the case of I zone (350a), the light weight safety status information for the buildings within it is set to E (highest risk grade), and in the case of II zone (350b), it is downgraded by two grades, and in the case of III zone (350c), In the case of one grade downgrade, outside the III zone (350d), the grade may not be downgraded and it can be marked as a caution area.

FIG. 17 is a diagram illustrating changing compact safety state information and precise safety state information when a fire occurs on a specific floor 410 of the building 400 .

Referring to FIG. 17 , in the case where a fire does not occur in the building 400 ( FIG. 17 ( a )), a fire occurs on a specific floor 410 of the building 400 , even if it is grade A for the entire floor. When (Fig. 17 (b)) the fire generation layer 410 is downgraded to E grade (highest risk grade) with compact safety status information and precise safety status information, and the surrounding layer 420 of the fire generation layer 410 is D It can be downgraded to a grade. A layer 430 other than the fire-generating layer 410 and the surrounding layer 420 may be downgraded to a C rating. And, when the fire spreads and the fire spreads to the surrounding layer 420 of the fire-generating layer 410 (FIG. 17(c)), the reference numeral 420 becomes the fire-generating layer and becomes an E grade, and the reference numeral 430 denotes the surrounding layer. This could be a D-class.

18 and 19 are diagrams illustrating examples of changing precise safety state information when a fire occurs in a specific area.

Referring to FIGS. 18 and 19 , the building is exemplified as a school, and there may be a plurality of zones composed of rooms therein, and a safety state grade may be set for each zone. Each zone may contain several sensors necessary to confirm a change in the safety state.

It was assumed that a fire occurred in the science preparation room among multiple areas. When a fire occurs in the science preparation room, the safety status level can be changed rapidly due to the dangerous or flammable substances present therein. And, in the case of a fire, since it can spread to other areas, there may be a change in the safety status rating of other areas. The fact that a fire occurred in the science preparation room can be confirmed through various sensors that exist inside the science preparation room, such as a wireless fire detection sensor, a complex sensor (temperature and humidity, fine dust, etc.), and a motion sensor. And, the degree of diffusion to other areas can be inferred through the opening/closing sensor.

In addition to the science preparation room, it is possible to infer the change of the safety status level for other areas within the school, such as the science room, music room, and computer room. In addition, a relatively safe area can be identified according to the degree of change in the safety status level for each area, and an evacuation route can be set for evacuation toward the safe area through a passage such as a corridor located between the areas. That is, the personnel located in the school can evacuate to the outside or a safe place through the evacuation route.

In this way, the precise safety status level change and evacuation route of each zone can be visualized and displayed through a monitor, a terminal liquid crystal, and the like. With the visualized information, the user can more intuitively and easily check the current safety status of a plurality of zones, and through this, the future precise safety status change situation and corresponding countermeasures can be established.
