Description

METHOD AND SYSTEM FOR MANAGING SAFETY OF FACILITY

[0001] The present disclosure relates to a method of managing the safety of a facility by using a computing device.

[0002] Structures such as bridges, tunnels, ports, dams, buildings, and ancillary facilities thereof built during construction works may age or develop defects over time. Consequently, safety inspections have been conducted recently on structures and social infrastructure and relevant regulations have been enacted to prevent significant damage to lives and property caused by unforeseen accidents.

[0003] Facilities are classified into Class-I facilities, which are large-scale facilities that require special management or advanced technology for structural safety and maintenance to promote convenient and safe public use, Class-II facilities, which are at high risk of disaster or require continuous management to prevent disasters and include infrastructure other than Class-I facilities, and Class-III facilities, which are small-scale facilities that require safe management and are at high risk of disaster or require continuous management to prevent disasters, such as facilities used by the general public, other than Class-II and Class-II facilities. Inspection of facilities are conducted according to the above classes.

[0004] Inspection and management of a facility may be carried out by a facility inspector who performs a safety inspection on site, analyzes damage to the facility, and reports inspection results, a facility manager who reviews the results of the safety inspection and determines whether the facility should be repaired, and a facility maintenance worker who performs a repair on the facility and reports results of the repair.

[0005] In a case in which each entity separately creates and manages data regarding the facility and a task on the facility, information about the facility, results of safety inspection and maintenance of the facility, etc. may not be accurately conveyed to other entities, and the task processing speed may decrease due to incompatibility between pieces of data being exchanged.

[0006] Therefore, there is a need for a technology that allows for accurate management of information about inspections and repairs among facility inspectors, managers, and maintenance workers.

[0007] The present disclosure provides a method of managing the safety of a facility and a system for performing the method.

[0008] In addition, the present disclosure provides a management method and system for managing information about a facility, information used in safety management procedures, and assisting a user in performing a task by using the information.

[0036] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0037] FIG. 1 schematically illustrates a facility safety management system and other components, according to an embodiment of the present disclosure.

[0038] A facility safety management system 100 (hereinafter referred to as a "system") of according to an embodiment of the present disclosure may be a single computing device, a set of a plurality of computing devices connected to each other via a computer network, or a set of resources provided by a cloud service.

[0039] The system 100 may include at least one computing device, cloud service resource, and application software that perform the roles of a web application service, an artificial intelligence service, a file service, and a database.

[0040] The system 100 may be connected to a computer network to perform data communication with other components. The computer network may be, for example, the Internet, or one or more of subsets of the Internet, such as a personal area network (PAN), a local area network (LAN), a campus area network (CAN), a metropolitan area network (MAN), a wide area network (WAN), a radio access network (RAN), or an internet area network (IAN). The system 100 and other components may transmit or receive data by using a data communication protocol such as Transmission Control Protocol (TCP) / Internet Protocol (IP).

[0041] A facility inspector, a facility manager, and a facility maintenance worker, as users of the system 100, may access the system 100 by using their respective terminal devices 10, 20, and 30, respectively.

[0042] The facility inspector may use the first terminal device 10 to perform a safety inspection of the facility, analyze damage to the facility, and report a result. By using the first terminal device 10, the facility inspector may set a flight path and an operation of a drone for capturing photographs of facilities, classify the captured photographs by the facilities and their sections and components, and detect damage to the facilities from the captured photographs.

[0043] The facility manager may input and retrieve information about a facility, and a safety inspection result by using the second terminal device 20. By using the second terminal device 20, the facility manager may check a result of a safety inspection of the facility, determine whether to perform a repair, and depending on the determination, request the facility maintenance worker to perform the repair.

[0044] The facility maintenance worker may perform a repair of the facility and report a result, by using the third terminal device 30. By using the third terminal device 30, the facility maintenance worker may check information about the facility, damage information about the facility, and a region to be repaired, and perform a repair accordingly.

[0045] Each of the first to third terminal devices 10, 20, and 30 may be a computing device. Each of the first to third terminal devices 10, 20, and 30 may be, for example, any one of a smart phone, a tablet computer, a laptop computer, a personal digital assistant (PDA), a video game console, and a desktop computer. In addition, the first to third terminal devices 10, 20, and 30 may be connected to the computer network to perform data communication with the system 100.

[0046] Application software may be installed on each of the first to third terminal devices 10, 20, and 30, and may execute a task corresponding to a user input. The application software is a web browser and may transmit and receive data to and from the system 100 through Hypertext Transfer Protocol (HTTP) or Hypertext Transfer Protocol Secure (HTTPS). Alternatively, the application software is a program that implements a client-server structure, and may transmit and receive data to and from the system 100 through TCP / IP.

[0047] FIG. 2 schematically illustrates a configuration of the facility safety management system 100, according to an embodiment of the present disclosure.

[0048] The system 100 may include a facility information management module 110, a damage information generation module 120, and a reporting module 130. Each component may be a computing device or application software running on a computing device. Alternatively, each component may be a resource running on a cloud service.

[0049] The facility information management module 110 may store information about a facility and information used in safety management procedures, and may provide the first to third terminal devices 10, 20, and 30 with reports and dashboards on damage information for each facility, section, and component.

[0050] Information about a facility includes the characteristics of the facility, and may include, for example, the name, location, area, purpose, type, structure, completion date, and the like of the facility.

[0051] Information used in safety management procedures of a facility includes information used in a series of procedures from safety inspections to repairs, and may include, for example, the name, executer, execution date, execution details, execution result, and the like of each safety inspection and maintenance procedure.

[0052] The facility manager may input information about a facility, and information used in safety management procedures, by using the second terminal device 20. By using the second terminal device 20, the facility manager may input information about a safety inspection procedure performed on a facility, and information about a repair procedure determined based on a safety inspection. The second terminal device 20 may transmits the input information to the system 100, and the facility information management module 110 may process and store received information.

[0053] The facility information management module 110 includes a database and may store information about a facility, safety inspection procedure information, repair procedure information, and the like, in tables of the database, respectively.

[0054] FIG. 3 illustrates an example of a damage information report stored by a facility information management module, according to an embodiment of the present disclosure.

[0055] The report may include the name, sections, and components of a facility, and an assessment result and a type of damage for each component. For example, as illustrated in FIG. 3, the report may show that, in a "main bridge" section of a "large bridge A", which is a facility, the condition of a component "bridge deck pavement" is "C", and damage types "crazing" and "crack (0.3 mm or longer)" have occurred in the component "bridge deck pavement", the condition of a component "abutment / pier" is "B", and damage types "crazing", "crack (0.3 mm or longer)", "breakage", "exposed reinforcing steel", and "spalling" have occurred in the component "abutment / pier". In addition, the report may show that, in a section "approach bridge 1", the condition of a component "girder" is "B", damage types "missing and defective bolt fastening", "defective welding", "corrosion", and "coating peeling" have occurred in the component "girder", the condition of a component "expansion joint" is "C", and damage types "efflorescence", "deterioration", "breakage", and "coating peeling" have occurred in the component "expansion joint".

[0056] In response to an inquiry request received from the terminal device 10, 20, and 30 of the users, the facility information management module 110 may transmit stored information (e.g., information about a facility or information used in facility safety management procedures) to the terminal device 10, 20, and 30 of the users.

[0057] The facility information management module 110 may store information about sections and components included in a facility. The sections may refer to respective regions in the facility, and the components may refer to respective functional components of the facility.

[0058] FIG. 4 illustrates an example of information about sections and components stored by a facility information management module, according to an embodiment of the present disclosure.

[0059] Information about sections and components may be stored in a table in a database, and columns of the table may include the name of the facility, the names of sections belonging to the facility, the names of components belonging to the sections, and one or more attributes of the components. Alternatively, the database storing information about sections and components may construct a table including identification information and names of facilities, a table including identification information and names of sections, and a table including identification information and names of components, and construct a table including, as columns, identification information about the facilities, the sections, and the components, and one or more attributes, by referring to the tables.

[0060] The facility manager may input information about sections and components of a facility by using the second terminal device 20. The second terminal device 20 may transmits the input information to the system 100, and the facility information management module 110 may process and store received information.

[0061] The facility information management module 110 may store drawings of components. The drawings may be files that are readable by computer-aided design (CAD) application software, and for example, may be in the Drawing Interchange Format (DXF).

[0062] FIG. 5 illustrates an example of a drawing of a component stored by a facility information management module, according to an embodiment of the present disclosure.

[0063] As illustrated in (a) of FIG. 5, the facility information management module 110 may store an original drawing of a component. In addition, as illustrated in (b) of FIG. 5, the facility information management module 110 may store a drawing of a component indicating damage detected by performing a safety inspection. The facility information management module 110 may display a figure or an icon corresponding to a type of damage, at a location where the damage occurred in the component.

[0064] Each time a safety inspection is performed, the facility information management module 110 may generate a drawing of the component indicating damage detected during the safety inspection. Alternatively, each time a safety inspection is performed, the facility information management module 110 may accumulate and display detected damage on a single drawing of the component. Here, detected damage may be indicated separately for each safety inspection performed. For example, damage detected during a first safety inspection may be indicated in red, and damage detected during a second safety inspection may be indicated in blue.

[0065] The facility manager may transmit a drawing of a component to the system 100 by using the second terminal device 20. The facility information management module 110 may store a received drawing of a component, and record an identification number of the component, and a storage location of the drawings, in a table of the database.

[0066] The facility information management module 110 may calculate a quantity of damage to a component, and obtain trend information about the quantity of damage by performing time-series analysis.

[0067] FIG. 6 illustrates an example of a quantity of damage and trend information both obtained by a facility information management module, according to an embodiment of the present disclosure.

[0068] A quantity of damage may include the total area of damage, a unit of measurement, and information about the number of occurrences, for each damage that has occurred in a component. In the example, it may be calculated that, for a component "bridge / pier" in a section "main bridge" of a facility "large bridge A", 330 "cracks shorter than 0.3 mm" with a total length of 2236.5 mm have been detected during a second safety inspection. In addition, it may be calculated that 49 "cracks of 0.3mm or longer" with a total length of 209.2 mm, 24 instances of "crazing" with a total area of 1946 ㎡, 64 instances of "spalling" with a total area of 58.58 ㎡, and 61 instances of "peeling" with a total area of 170.3 ㎡ have been detected.

[0069] The facility information management module 110 may calculate a trend of a quantity of damage by comparing the quantity of damage with a quantity of damage that has been calculated in a previous safety inspection. For each damage type that has occurred in a component, the facility information management module 110 may obtain trend information by calculating a difference in the quantity of damage between two safety inspections. For example, because a quantity of damage for "crack less than 0.3 mm" is 93.5 mm in the first inspection, and is 2236.5 mm in the second inspection, a trend in the quantity of damage may be calculated as 2236.5 mm - 93.5 mm = 2143.5 mm.

[0070] Alternatively, the facility information management module 110 may include a machine learning model, and may train the machine learning model by using calculated quantities of damage as training data. The machine learning model may be, for example, an autoregressive integrated moving average (ARIMA) model, a linear regression model, a recurrent neural network (RNN), a long short-term memory (LSTM), a transformer, or the like.

[0071] By using the second terminal device 20, the facility manager may transmit, to the system 100, a request to calculate a quantity of damage to a component and perform a time-series analysis of a trend of the quantity of damage. In response to the request, the facility information management module 110 may calculate the quantity of damage, perform a time-series analysis of the trend of the quantity of damage, and then process and store the obtained information.

[0072] The damage information generation module 120 may indicate damage detected from a photograph of a facility, on a drawing of a component, and store the drawing.

[0073] In response to information about a safety inspection procedure input to the system 100 by the facility manager, the facility inspector may photograph a facility by using a drone, or photograph the facility by using a photographing device, to obtain a photograph of the facility.

[0074] The first terminal device 10 may execute first application software installed thereon. In a user interface displayed on the first terminal device 10 by the first application software, the facility inspector may input a command to set a flight path and perform automatic flight.

[0075] The first application software is a web browser, and may receive a web page including a user interface from the system 100. Alternatively, the first application software may be provided by an application store of a platform to which the first terminal device 10 belongs, and a user interface may be programmed inside the first application software.

[0076] In the user interface, the facility inspector may set a flight path of a drone, and set an operation to be performed at each point on the path. For example, an operation of capturing a photograph of a facility from a point near the facility may be set.

[0077] After the facility inspector completes the task of setting the flight path, the first terminal device 10 may store the flight path set by the facility inspector, and information about the operation to be performed, and transmit them to the system 100.

[0078] In the user interface, the facility inspector may select a menu item for performing an automatic flight of the drone. The first terminal device 10 may transmit a command to start from a start point, move to a next set point, and perform an operation at the point, directly to the drone, or to the drone via the system 100. Alternatively, the first terminal device 10 may transmit data including a flight path and information about an operation to be performed, directly to the drone, or to the drone via the system 100. The drone may perform flight to a next point and photograph the facility by referring to point locations stored in the received data.

[0079] Alternatively, the first terminal device 10 may transmit, to the system 100, a photograph captured manually by a user using a drone, or a photograph obtained directly by the user using a photographing device.

[0080] Optionally, the first terminal device 10 may classify photographs of a facility, and then transmit them to the system 100.

[0081] The first terminal device 10 may execute second application software installed thereon. In a user interface displayed on the first terminal device 10 by the second application software, the facility inspector may input a command to classify photographs of a facility.

[0082] The second application software is a web browser, and may receive a web page including a user interface from the system 100. Alternatively, the second application software may be provided by an application store of a platform to which the first terminal device 10 belongs, and a user interface may be programmed inside the second application software.

[0083] In the user interface, the facility inspector may select a menu item for classifying photographs of a facility. When the facility inspector selects a menu item for automatically classifying photographs of a facility, the first terminal device 10 may group and classify photographs of a facility by section and component. Otherwise, when the facility inspector selects a menu item for manually classifying photographs of a facility, the first terminal device 10 may provide a user interface that allows the facility inspector to manually group icons displayed on a map corresponding to photographs of a facility.

[0084] The first terminal device 10 may classify the photographs of the facility by using a machine learning model. Alternatively, the first terminal device 10 may transmit the photographs of the facility to the system 100, and the system 100 may classify the photographs of the facility by using a machine learning model. The machine learning model may be, for example, K-means clustering, K-nearest neighbors, or a deep neural network.

[0085] The first terminal device 10 or the system 100 may sort the photographs of the facility based on metadata (e.g., latitude, longitude, or altitude) included in the photographs of the facility, and then classify the photographs of the facility by section and component.

[0086] The classified photographs may be transmitted to the system 100, and the system 100 may store the received photographs, or photographs that it has classified.

[0087] Optionally, the first terminal device 10 may detect damage from classified or unclassified photographs of a facility, and then transmit the damage to the system 100.

[0088] The first terminal device 10 may execute third application software installed thereon. In a user interface displayed on the first terminal device 10 by the third application software, the facility inspector may input a command to detect damage from a photograph of a facility.

[0089] The third application software is a web browser, and may receive a web page including a user interface from the system 100. Alternatively, the third application software may be provided by an application store of a platform to which the first terminal device 10 belongs, and a user interface may be programmed inside the third application software.

[0090] In the user interface, the facility inspector may select a menu item for detecting damage from a photograph of a facility. The first terminal device 10 may detect the location of damage and a region occupied by the damage, from a photograph of a facility.

[0091] The first terminal device 10 may detect damage by inputting a photograph of a facility to a machine learning model. Alternatively, the first terminal device 10 may transmit a photograph of a facility to the system 100, and the system 100 may detect damage by inputting the photograph of the facility to a machine learning model. The machine learning model may be, for example, a convolutional neural network, a model derived from a convolutional neural network, or a You Only Look Once (YOLO) model.

[0092] Alternatively, the first terminal device 10 may provide a user interface that allows the facility inspector to draw damage on an image of the facility.

[0093] Damage information detected or drawn may be transmitted to the system 100, and the system 100 may store the received damage information, or damage information that it has detected.

[0094] FIG. 7 is a diagram illustrating a process of indicating damage information on a drawing of a component, according to an embodiment of the present disclosure.

[0095] The damage information generation module 120 may obtain a photograph of a facility, and damage information detected from the facility, from the first terminal device 10, or may obtain those stored in the system 100.

[0096] The damage information generation module 120 may receive, as input, a photograph of a facility, and damage information about the facility, and extract damage vector data. The damage vector data may include information about a location of damage and a region occupied by the damage, in the photograph of the facility.

[0097] The damage information generation module 120 may calculate damage vector data by inputting, to a machine learning model, the photograph of the facility, and the damage information about the facility. Alternatively, the damage information generation module 120 may calculate damage vector data by calculating a vector corresponding to the location of the damage, and the region occupied by the damage.

[0098] The damage information generation module 120 may obtain information about a component that the photograph of the facility has been classified as, and then retrieve a drawing of the component from the facility information management module 110.

[0099] The damage information generation module 120 may indicate detected damage on the retrieved drawing of the component, in correspondence with the damage vector data. The damage information generation module 120 may indicate all detected damage on the drawing of the component, and then transmit the drawing to the facility information management module 110. The facility information management module 110 may store the drawing of the component on which the damage is indicated, separately from the original drawing, and stored drawings on which previously detected damage is indicated.

[0100] In response to a user's request, the facility information management module 110 may transmit the drawing of the component on which the detected damage is indicated, to the terminal device 10, 20, or 30 of the user.

[0101] By using the second terminal device 20, the facility manager may check a quantity of damage to a component, a trend of the quantity of damage and a drawing of the component on which detected damage is indicated, and determine a target to be repaired in the component, and a region to be repaired in the component. The application software running on the second terminal device 20 may display a user interface that allows the facility manager to set a region to be repaired on a drawing of a component. By using the second terminal device 20, the facility manager may set a region to be repaired by inputting the coordinates of the region to be repaired or by drawing a figure corresponding to the region to be repaired. The second terminal device 20 transmits, to the system 100, information about the region to be repaired that is set by the facility manager, and the facility information management module 110 may store the information.

[0102] FIG. 8 is a diagram illustrating an example of a user interface displayed on a terminal device of a facility maintenance worker, according to an embodiment of the present disclosure.

[0103] By using the third terminal device 30, the facility maintenance worker may check a target to be repaired in a component, and a region to be repaired in the component, and perform a repair. The application software running on the third terminal device 30 may display a user interface that shows the region to be repaired in the component, and receives an input of a region where a repair has been completed.
