Description

Safety Management System and Its Use Method

[0001] The present invention relates to a safety management system for elevator operators and a method for using the same. More specifically, the present invention relates to a system for managing the safety of elevator operators and a method for managing the safety of elevator operators using the system.

[0002] Elevators are installed and operated in high-rise and low-rise buildings, such as apartments, buildings, and government offices. Elevators encompass various areas, such as pits, shafts, cages, and machine rooms, each housing various components necessary for the elevator's operation. Elevators connect the building or structure from the lowest to the highest floors, and their structures are complex.

[0003] To keep these elevators safe, maintenance tasks such as regular inspections and repairs are essential, and these tasks are performed by human operators. Elevators typically feature complex structures, diverse components, and diverse structures, which can expose operators to hazardous environments due to various variables. Furthermore, external factors, such as the elevator's installation environment and seasonal variations, as well as the aging of elevator components, can expose operators to hazardous environments. Therefore, measures are needed to ensure a safe working environment for operators.

[0004] The problem to be solved by the present invention is to provide an integrated and systematic risk safety management system to ensure the safety of workers during elevator maintenance work.

[0005] Another problem to be solved by the present invention is to provide a safety management system that provides workers with on-site risk factors in advance and in real time, and a method of using the system.

[0006] Another challenge of the present invention is to provide a safety management system capable of recording and sharing new risk factors identified in the field, and a method of using the system.

[0007] Another object of the present invention is to provide a safety management system having an active warning system linked to the working status of a worker and a method of using the system.

[0008] According to one embodiment of the present invention, a safety management system is provided, including a safety management server that stores risk information for each elevator and a terminal that outputs the risk information for each elevator received from the safety management server through an application. The safety management server may include a risk information storage device and a risk information management device. The risk information storage device may store the risk information for each elevator. In addition, the risk information management device may transmit the risk information for the elevator requested from the terminal from among the risk information for each elevator stored in the risk information storage device to the terminal. Here, the risk information may be information on risk factors that hinder the safety of a worker performing management work for the elevator.

[0009] The above risk factors may include components and structures constituting the elevator and objects located inside and outside the elevator.

[0010] Additionally, the risk information may include information about the location and status of the risk factor.

[0011] The above risk information may include major risk items and location-specific risk items. Here, the major risk items may be risk factors that occur commonly regardless of the elevator's location. Furthermore, the location-specific risk items may be risk factors that occur depending on the elevator's location.

[0012] The above risk information may further include at least one of a photo and a video of the risk factor.

[0013] The above risk information may further include safety measures for the above risk factors.

[0014] The terminal may transmit new risk information input through the application to the safety management server. At this time, the risk information management device may update the risk information so that the new risk information received from the terminal is reflected in the risk information of the elevator stored in the risk information management device. Here, the new risk information may be stored in the safety management server and include risk information different from the risk information of the elevator output through the terminal.

[0015] The above safety management server may further include a risk notification device that transmits a risk notification signal to the terminal.

[0016] The above risk information management device can receive information about an elevator requiring management work and a worker assigned to the elevator from outside the safety management server. Here, the outside of the safety management server can be a terminal communicating with the safety management server or an administrator inputting information into the safety management server. Then, if risk information about the elevator exists in the risk information storage device, the risk information management device can transmit a signal for notification to the risk notification device. In addition, if the risk notification device receives a signal from the risk information management device, the risk notification signal can be transmitted to the terminal of the worker assigned to the elevator.

[0017] Upon receiving the danger alert signal from the safety management server, the terminal may output a danger alarm to the outside. For example, the terminal may display the danger alert signal on its screen or output a sound through its speaker to notify an operator outside the terminal.

[0018] According to another embodiment of the present invention, a safety management method is provided, including a step in which a terminal requests risk information about an elevator from a safety management server based on input from a worker, a step in which the safety management server transmits the risk information about the elevator to the terminal, and a step in which the terminal outputs the received risk information.

Here, the new risk information may include risk information that is different from the risk information of the elevator output through the terminal and stored in the safety management server.

[0026] In the step of updating the risk information by the safety management server, the risk information storage device can update the risk information so that the new risk information received from the terminal is reflected in the risk information of the elevator stored in the risk information management device.

[0027] The above safety management method may further include, before the step of the terminal requesting the safety management server for the risk information of the elevator according to the input of the worker, the step of the safety management server transmitting a risk notification signal to the terminal, and the step of outputting a risk alarm to the outside when the terminal receives the risk notification signal from the safety management server. Here, outputting the risk notification to the outside means outputting the risk notification to the screen or speaker of the terminal so that a worker located outside the terminal can visually or audibly confirm it.

[0028] In the step where the safety management server transmits a risk notification signal to the terminal, the risk information management device receives information about an elevator requiring management work and a worker assigned to the elevator from outside the safety management server, and if risk information about the elevator exists in the risk information storage device, it can transmit a signal for notification to the risk notification device.

[0108] Hereinafter, the safety management system and safety management method of the present invention will be described in detail through drawings.

[0109] [Configuration of the safety management system according to the first embodiment]

[0110] Figure 1 is a block diagram showing a safety management system according to a first embodiment of the present invention.

[0111] The safety management system (10) and safety management method according to an embodiment of the present invention are intended to ensure the safety of workers from risks that may occur at a site where an elevator is managed.

[0112] Referring to FIG. 1, a safety management system (10) according to an embodiment of the present invention may include a terminal (200) and a safety management server (101).

[0113] The terminal (200) is a device connected to the safety management server (101) via a communication network and capable of displaying information on a screen or through sound so that the user can input information or confirm the results of information processing visually or audibly. For example, the terminal (200) may be a portable device, such as a smartphone or tablet, on which applications can be installed.

[0114] The safety management server (101) is connected to a terminal (200) and can collect information on risk factors from the terminal (200). Furthermore, the safety management server (101) can monitor risk factors at each site using the collected risk information. Furthermore, according to the present embodiment, the safety management server (101) can be connected to at least one terminal (200). Here, the site may be the interior or exterior of an elevator cage where workers are stationed and require management. Here, management and maintenance tasks refer to all actions performed by workers for the maintenance and upkeep of the elevator. For example, management and maintenance tasks may include regular inspections for elevator maintenance and repairs to resolve elevator malfunctions.

[0115] Referring to FIG. 1, the safety management server (101) may include a risk information storage device (110) and a risk information management device (120) that analyzes risk information.

[0116] The risk information storage device (110) can store risk information collected for each site. Risk information is information on risk factors discovered by previous workers at each site. Risk factors can be anything that could pose a risk to workers when performing elevator maintenance work inside or outside the elevator. For example, a risk factor can be any component, structure, or object located inside or outside the elevator that threatens the safety of workers. Furthermore, risk information can include any information related to risk factors, such as the location or status of the risk factor, the time of occurrence or discovery of the risk factor, and the method of handling the risk factor.

[0117] The risk information management device (120) can manage information about risk factors received from the terminal (200). For example, the risk information management device (120) can transmit the risk information received from the terminal (200) to the risk information storage device (110). Here, the risk information can include initial risk information for the corresponding site and new risk information that includes information different from previous risk information. In addition, the risk information management device (120) can update the risk information storage device (110) with the new risk information received from the terminal (200). For example, the new risk information can be information different from the risk information previously stored in the risk information storage device (110). Therefore, the safety management system (10) can reflect the new risk information received from the terminal (200) into the risk information stored in the risk information storage device (110) to monitor the risk factors and risk environment of each site in real time.

[0118] The terminal (200) is a device that allows workers performing elevator maintenance work to input information about hazards discovered on-site or to check information about hazards at the site before arriving at the site. For example, the terminal (200) can transmit hazard information entered by the worker to the safety management server (101). In addition, the terminal (200) can receive hazard information at the site from the safety management server (101) and display it on the screen for the worker to check.

[0119] The safety management system (10) of an embodiment of the present invention may include a plurality of terminals (200). The plurality of terminals (200) may be any device on which an application capable of transmitting and receiving information to and from a safety management server (101) is installed. The plurality of terminals (200) may all be the same type of device on which an application connecting to the safety management server (101) is installed. Alternatively, the plurality of terminals (200) may be different types of devices on which an application connecting to the safety management server (101) is installed. In this way, the plurality of terminals (200) may be any device on which an application connecting to the safety management server (101) is installed and which can transmit and receive risk information to and from the safety management server (101) through the installed application.

[0120] The operation of the safety management system (10) according to an embodiment of the present invention will be described in detail through an embodiment of the following safety management method.

[0121] [Example of the operation sequence and usage method of the safety management system according to the first embodiment]

[0122] Figure 2 is a flowchart illustrating a safety management method of a safety management system according to a first embodiment of the present invention. Furthermore, Figures 3 to 9 are exemplary drawings illustrating the safety management method of the safety management system through an application installed on a worker's terminal (200). Specifically, Figures 3 to 9 are drawings illustrating applications displayed on the screen of a worker's terminal (200).

[0123] The safety management method according to the first embodiment of FIG. 2 can be implemented through the safety management system (10) of FIG. 1.

[0124] A worker performing elevator maintenance may be deployed to the site where the elevator is located when elevator maintenance, such as elevator breakdown repair or regular inspection, is required.

[0125] The safety management method of the safety management system (10) can be initiated when a worker is deployed to a site requiring repair or regular inspection through a terminal (200) or other device.

[0126] First, the terminal (200) can request risk information from the safety management server (101) (S11).

[0127] When a worker is deployed to a site, the worker can request risk information of the site to the safety management server (101) through an application installed on the terminal (200).

[0128] Figure 3 is an example of a screen displayed on a terminal (200) when an application installed on the terminal (200) is executed. When a worker executes an application installed on the terminal (200), a site list (510) listing sites where the worker is assigned or managed may be displayed on the screen of the terminal (200).

[0129] The site list (510) may display brief information, such as the name, address, and last inspection date of each site. Additionally, the site list (510) may display information indicating the worker status for each site. Here, the worker status may be information regarding the worker's current status, such as whether the worker has left the site, whether maintenance work is in progress, or whether maintenance work has been completed.

[0130] The site list (510) may indicate whether or not a risk factor exists at each site. The presence of a risk factor may be indicated in various ways, such as by color, text, or pictures.

[0131] For example, the screen output through the application may include a notification area (520), and the notification area (520) may display the worker's status and the presence of a risk factor, as illustrated in FIG. 3. The notification area (520) may indicate the presence of a risk factor at the site with a border color and text. For example, if a risk factor exists at the site, the border of the notification area (520) may be displayed in red, and risk factor text may be displayed within the notification area (520). Furthermore, the red border of the notification area (520) may blink in order to clearly inform the worker of the presence of the risk factor. That is, a worker status display area (521) in which the worker's status is displayed, and a risk factor display area (522) in which the presence of a risk factor is displayed, may be located within the notification area (520).

[0132] The worker can touch the notification area (520) of the site using a finger or tool to check detailed information about the hazards of the site where the worker is deployed.

[0133] The terminal (200) can transmit a signal requesting risk information of the site to the safety management server (101) according to the input of the worker.

[0134] The safety management server (101) can transmit the requested risk information of the corresponding site to the terminal (200) (S12).

[0135] The risk information management device (120) can receive a signal requesting risk information of a corresponding site from the terminal (200). The risk information management device (120) can transmit the requested risk information of the corresponding site from among the risk information stored in the risk information storage device (110) to the terminal (200). For example, the signal transmitted by the terminal (200) to the safety management server (101) can include identification information that can identify the corresponding site. In addition, the risk information management device (120) can identify the requested risk information of the corresponding site from among numerous pieces of information stored in the risk information storage device (110) through the identification information included in the received signal and transmit the information to the terminal (200).

[0136] The terminal (200) can output the risk information of the corresponding site received from the safety management server (101) (S13).

[0137] The terminal (200) can output the risk information of the site received from the safety management server (101) through a screen so that the worker can visually check it.

[0138] The worker can check detailed descriptions of the risk factors at the site through the risk information displayed on the screen of the terminal (200). Figures 4 and 5 are drawings explaining a method for checking risk information at the site through an application of the terminal (200).

[0139] Figure 4 is an example diagram showing the risk items of the corresponding site displayed on the terminal (200) screen.

[0140] Referring to FIG. 4, risk items may include major risk items (610) and location-specific risk items (620).

[0141] The major risk items (610) may list the major risk factors of the site. Here, the major risk factors are risk factors that occur frequently at the site, regardless of the area or location. In other words, the major risk items (610) may be risk factors caused by devices or structures that are commonly included in each area of ​​the site. Here, the areas of the site may be parts that make up the elevator, such as the elevator pit, platform, elevator shaft, cage, and machine room, as well as parts that make up the elevator. For example, the major risk items (610) may include risk factors such as a lighting short circuit or loose fixing of a structure.

[0142] Additionally, the location-specific risk items (620) may be risk factor items that occur at each location.

[0143] For example, the location-specific risk items (620) may include major risk items (610), and the major risk items (610) may be separated by location in the field.

[0144] Even for the risk factors included in the major risk items (610), the methods for eliminating or preventing risks caused by the risk factors may vary depending on the location. For example, the location of lighting, illumination, and power supply methods may vary depending on the inside of the cage, the machine room outside the cage, the platform, and the pit. Accordingly, the location-specific risk items (620) may include risk factors for each location in the site and safety measures for each risk factor. Here, safety measures are methods for resolving risks, such as preventing or eliminating risks that may arise from the risk factors.

[0145] Additionally, location-specific risk items are not included in the main risk items (610), and may include risk factors and risk resolution methods for devices and structures installed in each area. For example, location-specific risk items (620) may be categorized into machine rooms, platforms, elevator shafts, pits, and cages, and each location item may include risk factors and corresponding safety measures. Workers can prepare to ensure safety from the corresponding risk factors through safety measures.

[0146] Referring to FIG. 4, risk information may include audiovisual information (630) that allows visual confirmation of risk factors registered in the application through the terminal (200) screen. The audiovisual information (630) may be a photograph or video that allows visual and auditory confirmation of the status of the risk factors registered in the risk information. Through the audiovisual information (630), workers can more accurately confirm the status of the risk factors.

[0147] Figure 5 is an example diagram showing audiovisual information (630) of a risk factor displayed on the screen of a terminal (200).

[0148] Referring to Fig. 5, audiovisual information (630) can be checked through the screen of the terminal (200). If the risk information of the site includes multiple audiovisual information (630), the worker can select the desired audiovisual information (630) and check the corresponding risk factor. The worker can accurately determine the location, shape, status, etc. of the risk factor through the audiovisual information (630). In addition, the audiovisual information (630) can be enlarged or reduced according to the worker's adjustment. For example, the worker can enlarge or reduce the screen on which the audiovisual information (630) is displayed using a finger or a tool. Therefore, the worker can check the information on the risk factor more accurately.

[0149] Through steps S11 (S11) to S13 (S13) of FIG. 2, the worker can check the risk information of the site in advance before arriving at the site using the terminal (200).

[0150] Before departing for a site, workers can review information about hazards and, based on this information, prepare the necessary equipment to eliminate or prevent hazards. This means workers can bring not only equipment for elevator maintenance and repairs, but also equipment necessary to eliminate hazards. Therefore, workers can not only perform requested repairs or maintenance routines, but also eliminate hazards that may have arisen on site. For example, if the hazard is a component failure, workers can repair the broken part to eliminate the hazard. Furthermore, if the hazard is electric shock from a component, workers can avoid touching the component or wear insulated gloves when performing requested maintenance tasks to prevent electric shock.

[0151] While performing maintenance and management tasks at a site, workers can discover new information about the site's hazards. Workers can transmit this new information to the safety management server (101) via an application on their terminal (200).

[0152] The terminal (200) can receive new risk information at the site (S14).

[0153] New risk information may include information that differs from the previously registered risk information for the site. For example, new risk information may include information on hazards newly discovered by workers at the site and those likely to become hazards in the future. Additionally, new risk information may include information on hazards that have already been eliminated or eliminated by current workers.

[0154] For example, while managing a site, a worker may discover a new risk factor that is not registered in the risk information confirmed through the terminal (200). At this time, the worker may register information about the new risk factor to the safety management server (101) through the application of the terminal (200). In addition, while managing the site, the worker may register information about factors that may become risk factors during future site management to the safety management server (101) through the application of the terminal (200).

[0155] [Example of registering new risk information using a terminal]

[0156] Figures 6 to 9 are drawings for explaining a method for registering new risk information through an application of a terminal (200).

[0157] Figure 6 is a start screen for registering new risk information displayed on the terminal screen.

[0158] Referring to FIG. 6, a worker can register new risk information by executing an application on a terminal (200) and writing a work log displayed on the screen of the terminal (200). Here, registering new risk information means adding new risk information to previous risk information or deleting or changing some of the risk information already registered.

[0159] The worker can select a risk factor management item (710) from the screen of the terminal (200) of Fig. 6.

[0160] Figure 7 is an example of a screen of a terminal (200) displayed when a worker selects a risk factor management item (710).

[0161] The worker can select a major risk factor item (810) or a location-specific risk factor item (820) from among the risk factor management items (710). The worker can register a risk factor by selecting only one of the major risk factor item (810) and the location-specific risk factor item (820). Alternatively, the worker can register a risk factor in both the major risk factor item (810) and the location-specific risk factor item (820).

[0162] FIG. 8 is an example of a screen output on a terminal (200) when a major risk factor item (810) of FIG. 7 is selected. Referring to FIG. 8, a list (811) of major risk factors may be output on the screen of the terminal (200). Here, the outputted major risk factors may be risk factors that commonly occur regardless of location or risk factors that occur frequently statistically. At this time, among the outputted list (811) of major risk factors, the list with check boxes already checked is a risk factor that has already been discovered and registered in the safety management server (101).

[0163] The worker can select one or more risk factors corresponding to new risk factors from among the major risk factors displayed on the screen of the terminal (200). Additionally, if there is no risk factor corresponding to new risk factors among the list displayed on the screen of the terminal (200), the worker can directly record information about the new risk factor.

[0164] Figure 9 is an example of a screen displayed on a terminal (200) when a location-specific risk item (620) of Figure 7 is selected.

[0165] Among the risk items (620) by location in Figure 7, the worker can select the location of a new risk factor. For example, the location of the new risk factor may be a machine room. If the worker selects a machine room, the terminal (200) may display the screen of Figure 9.

[0166] Referring to Figure 9, a list of risk factors can be output for each location within the site. When a worker selects the location of a new risk factor, a list of risk factors for that location can be output on the terminal (200) screen. For example, if the worker selects a machine room, a list of risk factors for that machine room can be output on the terminal (200) screen.

[0167] The worker can select one or more risk factors corresponding to a new risk factor from the list displayed on the screen of the terminal (200). For example, a new risk factor can be added by checking the check box of the risk factor corresponding to the new risk factor in the risk factor list.

[0168] Additionally, if there is no risk factor corresponding to a new risk factor among the list displayed on the screen of the terminal (200), the worker can directly record information on the new risk factor by location.

[0169] Additionally, when a worker selects a location for a new hazard, the list of hazards at that location is not the only thing displayed on the terminal (200) screen. For example, when a worker selects a location for a new hazard, a list of hazards at the selected location may be displayed in the central area of ​​the terminal (200) screen. At this time, the worker can simultaneously check lists of hazards at other locations as well as the selected location by manipulating the terminal (200) screen with a finger or tool.

[0170] Additionally, the worker can add audiovisual information (830) on new risk factors for each site through the terminal (200).

[0171] Additionally, when the worker arrives at the site, at least some of the risk factors registered in the safety management server (101) may have been removed. Alternatively, at least some of the risk factors registered in the safety management server (101) may be removed through the worker's management tasks. In this case, the worker may delete information about the removed risk factors from the safety management server (101) through the application of the terminal (200).

[0172] The operator can delete information about previously registered risk factors that have been removed from the list of major risk factors (810) and location-specific risk factors (820). For example, in FIGS. 8 and 9 , check boxes already checked in the list of major risk factors (811) and location-specific risk factors (821) are previously registered risk factors. Removal of a risk factor can be accomplished by unchecking the checkbox of the risk factor.

[0173] Additionally, the worker can remove audiovisual information (830) of the removed hazard.

[0174] In the embodiment of the present invention, adding or deleting a risk factor to an application of a terminal (200) is performed by checking or unchecking the checkbox for the corresponding risk factor. However, the present invention is not limited to this. That is, various methods can be used to input new risk information into the terminal (200).

[0175] The worker can input new risk information including information that adds a risk factor to the application of the terminal (200) or deletes a previous risk factor and select transmit on the screen of FIG. 6.

[0176] When the terminal (200) receives a transmission signal, it can transmit new risk information of the corresponding site to the safety management server (101) (S15).

[0177] The safety management server (101) can update new risk information received from the terminal (200) to the information storage device (S16).

[0178] The risk information management device (120) can compare previous risk information stored in the risk information storage device (110) with new risk information received from the terminal (200) and apply changes to the previous risk information.

[0179] Through this process, if the safety management server (101) updates the risk information of the site, the safety management stage of the safety management system (10) can be terminated.

[0180] Additionally, the terminal (200) may not receive new risk information (S14).

[0181] If the terminal (200) does not receive new risk information, the safety management phase of the safety management system (10) may also be terminated.

[0182] Although the embodiment of the present invention describes that the step of receiving new risk information by the terminal (200) is performed after the step of outputting risk information of the corresponding site by the terminal (200), the present invention is not limited thereto. For example, if risk information of the corresponding site does not exist, the step of receiving new risk information by the terminal (200) may be performed before or after the step of requesting risk information from the safety management server (101). In addition, in this case, the risk information management device (120) may store the received new risk information as risk information of the corresponding elevator in the risk information storage device (110).

[0183] According to the safety management system (10) and safety management method according to the embodiment of the present invention, workers deployed to a site for regular maintenance or repair can identify risk factors at the site in advance. Therefore, workers can prepare for risks that may occur at the site. For example, workers can prepare equipment to remove risk factors at the site and remove them at the site. In addition, workers can prevent the occurrence of risks by identifying the location and status of risk factors that may occur at the site. Therefore, the safety management system (10) and safety management method according to the embodiment of the present invention enable workers to identify risk factors at the site in advance and efficiently establish site management plans. In addition, the safety management system (10) and safety management method according to the embodiment of the present invention can improve the safety of on-site work, and thus, work efficiency.

[0184] For example, while inspecting a machine room, a worker may discover a connector with damaged wire insulation, exposing the internal conductor. In this case, the worker can register the risk factor as "Machine Room → Risk of Electric Shock" through the application on his / her terminal (200). At this time, the worker can attach a photo showing the condition of the risk factor through the application on his / her terminal (200) and also register safety measures such as "Insulation required." Afterwards, the next worker on the elevator can recognize the risk factor in the machine room through his / her terminal (200), prepare safety equipment such as insulating gloves in advance, and safely perform the task.

[0185] As another example, a worker may be aware of a falling hazard by discovering a box of parts not secured to the upper portion of a hoistway during an inspection. In this case, the worker can select "Hoistway" from the list of location-specific risk items through an application on their terminal (200) and register the item "Risk of Falling Temporary Parts Fixtures." This item may include a photo, the location of the hazard, the time of occurrence, and a response plan. Subsequently, the worker can use their terminal (200) to proactively identify areas at risk of falling objects and take safety measures, such as wearing protective gear and ensuring the parts are secured during work.

[0186] [Configuration of the safety management system according to the second embodiment]

[0187] The safety management system of the second embodiment of the present invention may further include a notification device, compared to the safety management system of the first embodiment. Therefore, the safety management system of the second embodiment of the present invention is characterized by implementing a pre-warning system and reducing the time it takes for workers to become aware of safety through real-time automatic warnings.

[0188] Figure 10 is a block diagram showing a safety management system according to a second embodiment of the present invention.

[0189] The safety management system (20) according to the second embodiment may include a terminal (200) and a safety management server (102). In addition, referring to FIG. 10, the safety management server (102) may include a risk information storage device (110), a risk information management device (120) that analyzes risk information, and a risk notification device (130) that sends a warning about a risk to a worker's terminal (200). The terminal (200), the risk information storage device (110), and the risk information management device (120) of the safety management system (20) of the present embodiment are identical to the terminal (200), the risk information storage device (110), and the risk information management device (120) of the safety management system (10) of the first embodiment of FIG. 1. Therefore, for a detailed description of the terminal (200), the risk information storage device (110), and the risk information management device (120) of the present embodiment, refer to the previous description. In addition, the description of the safety management system (20) of the present embodiment will be centered on the risk notification device (130) that is different from the safety management system of the first embodiment (10 of FIG. 1).

[0190] The risk notification device (130) of the safety management system (20) of this embodiment can transmit risk information to the worker's terminal (200) before the worker enters the site.

[0191] When a worker is deployed to a site for maintenance and repair, information about the worker deployed to the site can be entered and stored in the safety management server (102) by the manager. Here, the worker information may include information about not only the worker but also the worker's terminal (200). Furthermore, the manager may be the person who deploys the worker to the site requiring maintenance and repair. Alternatively, the manager may be a program or system that automatically deploys the worker to the site requiring maintenance and repair.

[0192] For example, a manager can transmit site information and information on workers deployed at the site to a risk information management device (120) of a safety management server (102). The risk information management device (120) can check whether risk information for the corresponding site is stored in the risk information storage device (110) based on the received site information. If risk information for the corresponding site exists in the risk information storage device (110), the risk information management device (120) can transmit a signal to a risk notification device (130).

[0193] When the risk notification device (130) receives a signal from the risk information management device (120), it can transmit a risk notification signal to the terminal (200) of a worker deployed at the site. More specifically, the risk notification device (130) can receive information about the site and the worker deployed at the site through the signal received from the risk information management device (120) and transmit a risk notification signal to the worker's terminal (200).

[0194] When the worker's terminal (200) receives a risk notification signal from the risk notification device (130) of the safety management server (102), it can output a risk alarm so that the worker can check the risk information. The risk alarm can be performed in various ways, such as an alarm, vibration, or light of the terminal (200).

[0195] For example, a worker may be deployed to a machine room for regular inspection. The risk information management device (120) may retrieve information about electric shock hazards registered in the machine room from information stored in the risk information storage device (110).

[0196] The hazard notification device (130) transmits a hazard notification signal, which is a warning signal corresponding to the hazard, to the worker's terminal (200). Based on the received hazard notification signal, the terminal (200) can output a warning message on the screen or immediately notify the worker of the hazard through an alarm or vibration via a speaker.

[0197] Workers can recognize potential electric shock hazards, such as damage to wire insulation, in advance through the corresponding warnings output from the terminal (200). Therefore, workers can ensure safety during work by preparing insulating gloves or insulating mats in advance.

[0198] In this way, the safety management system (20) according to the second embodiment of the present invention enables advance prevention by actively notifying workers of risk factors before they enter the site.

[0199] As such, the safety management system (20) of the present embodiment can notify workers of risk information at the relevant site in advance before the worker requests such information. Therefore, the step in which the safety management system (20) notifies workers of risk information at the relevant site via the terminal (200) may be performed before the step in which the terminal (200) requests risk information from the safety management server (102) among the steps of the safety management method of FIG. 2.

[0200] The safety management system (20) and safety management method according to this embodiment can notify workers in advance of the presence of hazards at a site, allowing them to search for information about the hazards at the site and prepare for them. Therefore, the safety management system (20) and safety management method according to this embodiment can ensure that workers are aware of the risks and perform their management tasks safely.

[0201] [Configuration of the safety management system according to the third embodiment]

[0202] Figure 11 is a block diagram showing a safety management system according to a third embodiment of the present invention.

[0203] The safety management system (30) and safety management method according to an embodiment of the present invention are intended to ensure the safety of workers from risks that may occur at a site where an elevator is managed.

[0204] Referring to FIG. 11, a safety management system (30) according to an embodiment of the present invention may include a terminal (230) and a safety management server (101).

[0205] The safety management server (101) is connected to a terminal (230) and can collect information on risk factors from the terminal (230). Furthermore, the safety management server (101) can monitor risk factors at each site using the collected risk information. Furthermore, according to the present embodiment, the safety management server (101) can be connected to at least one terminal (230). Here, the site may be the interior or exterior of an elevator cage where workers are stationed and require management. Here, management and maintenance tasks refer to all actions performed by workers for the maintenance and upkeep of the elevator. For example, management and maintenance tasks may include regular inspections for elevator maintenance and repairs to resolve elevator malfunctions.

[0206] Referring to FIG. 11, the safety management server (101) may include a risk information storage device (110) and a risk information management device (120) that analyzes risk information.

[0207] The risk information storage device (110) can store risk information collected for each site. Risk information is information on risk factors discovered by previous workers at each site. Risk factors can be anything that could pose a risk to workers when performing elevator maintenance work inside or outside the elevator. For example, a risk factor can be any component, structure, or object located inside or outside the elevator that threatens the safety of workers. Furthermore, risk information can include any information related to risk factors, such as the location or status of the risk factor, the time of occurrence or discovery of the risk factor, and the method of handling the risk factor.

[0208] The risk information management device (120) can manage information about risk factors received from the terminal (230). For example, the risk information management device (120) can transmit the risk information received from the terminal (230) to the risk information storage device (110). Here, the risk information can include initial risk information for the corresponding site and new risk information that includes information different from previous risk information. In addition, the risk information management device (120) can update the risk information storage device (110) with the new risk information received from the terminal (230). For example, the new risk information can be information different from the risk information previously stored in the risk information storage device (110). Therefore, the safety management system (30) can reflect the new risk information received from the terminal (230) into the risk information stored in the risk information storage device (110) to monitor the risk factors and risk environment of each site in real time.

[0209] The terminal (230) is a device that allows workers performing elevator maintenance work to input information about hazards discovered on-site or to check information about hazards at the site before arriving at the site. For example, the terminal (230) can transmit hazard information entered by the worker to the safety management server (101). In addition, the terminal (230) can receive hazard information at the site from the safety management server (101) and display it on the screen for the worker to check.

[0210] The safety management system (30) of an embodiment of the present invention may include a plurality of terminals (230). The plurality of terminals (230) are devices connected to the safety management server (101) via a communication network and capable of displaying information on a screen or through sound so that a user can input information or confirm the results of information processing visually or audibly. Furthermore, the plurality of terminals (230) may be any device equipped with an application capable of transmitting and receiving information to and from the safety management server (101).

[0211] According to an embodiment of the present invention, the terminal (230) may include a first terminal (231) and a second terminal (232).

[0212] The first terminal (231) communicates with the safety management server (101) and the second terminal (232), and can be any type of terminal capable of inputting and outputting risk information.

[0213] The first terminal (231) may include an application connected to the safety management server (101). That is, the first terminal (231) may exchange risk information with the safety management server (101) through the application. In addition, the first terminal (231) may transmit risk information received from the safety management server (101) to the second terminal (232). For example, the first terminal (231) may include all types of handheld-based wireless communication devices, such as a PCS (Personal Communication System), GSM (Global System for Mobile communications), PDC (Personal Digital Cellular), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet) terminal, smartphone, smartpad, tablet PC, etc.

[0214] The second terminal (232) can share risk information received by the first terminal (231) wirelessly or wiredly. For example, the first terminal (231) and the second terminal (232) can be connected to each other via a wireless communication method such as Bluetooth or Wi-Fi. Additionally, the first terminal (231) and the second terminal (232) can be connected via a wired communication method such as a cable.

[0215] Additionally, the second terminal (232) is worn on the worker's body and can output risk information received from the first terminal (231) in the form of text, photos, videos, and voices. The second terminal (232) may be a device having a structure that does not cause inconvenience to the worker when performing management tasks while wearing it.

[0216] The second terminal (232) may be a wearable device on the worker's body and include a display unit. For example, the second terminal (232) may be a display in the form of glasses. Furthermore, the second terminal (232) may be AR (Augmented Reality) glasses. If the second terminal (232) is in the form of glasses, the transparent glasses lens may serve as a display that displays risk information. Therefore, the second terminal (232) can enable the worker to check the risk information at the site without obstructing the worker's field of vision. Furthermore, since the second terminal (232) is worn on the worker's face in the form of glasses, the worker's hands and feet are free when checking the risk information. Therefore, the worker can check the risk information while performing management tasks simultaneously.

[0217] Additionally, the second terminal (232) may be a device that can be worn on the worker's body and includes an audio output unit. For example, the second terminal (232) may be in the form of earphones or headphones that can be worn on the worker's ears, or in the form of a speaker that can be worn on the worker's body. In this case, the second terminal (232) may convert text-based hazard information received by the first terminal (231) into voice and output it. In this case, the worker (232) can visually identify the corresponding hazard while listening to the voice-converted hazard information.

[0218] In addition, the second terminal (232) may be a wearable device on the worker's body, and may include both a display unit and an audio output unit. For example, the second terminal (232) may be a device equipped with a speaker or earphones on a glasses-type display. In other words, the second terminal (232) allows the worker to simultaneously check hazard information visually and audibly. For example, the second terminal (232) may output all hazard information displayed in text on the display as audio. Alternatively, the second terminal (232) may output detailed hazard information for the relevant site through the display and output a summary or summary of the hazard information through audio. Alternatively, the second terminal (232) may output an alarm indicating the presence of hazard information for the relevant site and output detailed hazard information through the display. In this case, the worker can double-check hazard information visually and audibly through the second terminal (232). Therefore, the worker can respond to all hazards without exception, thereby improving safety at the work site.

[0219] According to an embodiment of the present invention, the main function of the second terminal (232) is to output information transmitted by the first terminal (231). That is, the second terminal (232) cannot access the safety management server (101). Therefore, the first terminal (231) can access risk information through communication with the safety management server (101), but the second terminal (232) is restricted from accessing the risk information of the safety management server (101).

[0220] Alternatively, the second terminal (232) can be authenticated for access to information from the safety management server (101) through the first terminal (231). That is, it authenticates whether the second terminal (232) or the worker using the second terminal (232) has the authority to access information from the safety management server (101).

[0221] For example, the second terminal (232) can receive user authentication to confirm who the user of the second terminal (232) is through the first terminal (231) or authorization authentication to confirm whether the user of the second terminal (232) has the authority to access information of the safety management server (101). The worker can access information of the safety management server (101) through the second terminal (232) that has completed such authentication. Alternatively, the worker can access information of the safety management server (101) through the first terminal (231) only with the second terminal (232) that has received both user authentication and authorization authentication. Here, accessing information of the safety management server (101) through the second terminal (232) means that information of the safety management server (101) is transmitted to at least one of the first terminal (231) and the second terminal (231) according to a signal transmitted from the second terminal (232).

[0222] For example, a second terminal (232) that has completed all necessary authentication can transmit a request signal regarding risk information to the safety management server (101) through the first terminal (231). For example, the second terminal (232) that has completed authentication can include a configuration such as a button or a voice recognition unit, and can transmit a signal requesting risk information to the first terminal (231) through this configuration. For example, the voice recognition unit can be a microphone. When the first terminal (231) receives this signal, it can request and receive risk information of the corresponding site from the safety management server (101) through an application. Thereafter, the first terminal (231) can transmit the received risk information to the second terminal (232).

[0223] In this way, the safety management system (30) according to an embodiment of the present invention can prevent hacking from outside the system and strengthen system security by limiting the terminals that can access the risk information of the safety management server (101) or allowing only terminals that have completed authentication to access it.

[0224] The operation of the safety management system (30) according to an embodiment of the present invention will be described in detail through an embodiment of the following safety management method.

[0225] [Example of the operation sequence and usage method of the safety management system according to the third embodiment]

[0226] Fig. 12 is a flowchart illustrating a safety management method of a safety management system according to a third embodiment of the present invention. The safety management method of the safety management system according to the third embodiment of Fig. 12 is described with reference to example diagrams of applications displayed on the screens of worker terminals of Figs. 3 to 9 and an example diagram of a second terminal of Fig. 13.

[0227] The safety management method according to the third embodiment of FIG. 12 can be achieved through the safety management system (30) of FIG. 11.

[0228] A worker performing elevator maintenance may be deployed to the site where the elevator is located when elevator maintenance, such as elevator breakdown repair or regular inspection, is required.

[0229] The safety management method of the safety management system (30) can be initiated when a worker is deployed to a site requiring breakdown repair or regular inspection through a terminal (230) or other device.

[0230] The first terminal (231) or the second terminal (232) can request risk information from the safety management server (101) (S31).

[0231] The first terminal (231) can request risk information from the safety management server (101).

[0232] When a worker is deployed to a site, the worker can request risk information of the site to the safety management server (101) through an application installed on the first terminal (231).

[0233] Alternatively, the second terminal (232) may request risk information from the safety management server (101). In this case, the second terminal (232) requests risk information from the safety management server (101) through the first terminal (231).

[0234] In this case, a step of authenticating whether the second terminal (232) or the worker using the second terminal (232) has access to the risk information of the safety management server (101) must be performed first.

[0235] When the second terminal (232) receives information access authorization from the safety management server (101) through the first terminal (231), the worker can request risk information of the site from the safety management server (101) through the second terminal (232).

[0236] For example, a worker can receive information access authority authentication of a safety management server (101) of a second terminal (232) through a first terminal (231). At least one of user authentication and authority authentication of a worker using the second terminal (232) can be performed through the first terminal (231). When the authentication required for information access authority of the safety management server (101) through the second terminal (232) is completed, the worker can transmit a risk information request signal to the first terminal (231) through a button or voice recognition unit included in the second terminal (232).

[0237] When the first terminal (231) receives a signal from the second terminal (232), it can transmit a signal requesting risk information of the corresponding site to the safety management server (101). At this time, when the first terminal (231) receives a signal from the second terminal (232), an application installed in the first terminal (231) is automatically executed, and a signal requesting risk information can be transmitted to the safety management server (101) through the executed application.

[0238] Figure 3 is an example of a screen displayed on the first terminal (231) when the application installed on the first terminal (231) is executed. When a worker executes the application installed on the first terminal (231), a list of sites (510) where the worker is assigned or managed may be displayed on the screen of the first terminal (231).

[0239] The site list (510) may display brief information, such as the name, address, and last inspection date of each site. Additionally, the site list (510) may display information indicating the worker status for each site. Here, the worker status may be information regarding the worker's current status, such as whether the worker has left the site, whether maintenance work is in progress, or whether maintenance work has been completed.

[0240] The site list (510) may indicate whether or not a risk factor exists at each site. The presence of a risk factor may be indicated in various ways, such as by color, text, or pictures.

[0241] For example, the screen output through the application may include a notification area (520), and the notification area (520) may display the worker's status and the presence of a risk factor, as illustrated in FIG. 3. The notification area (520) may indicate the presence of a risk factor at the site with a border color and text. For example, if a risk factor exists at the site, the border of the notification area (520) may be displayed in red, and risk factor text may be displayed within the notification area (520). Furthermore, the red border of the notification area (520) may blink in order to clearly inform the worker of the presence of the risk factor. That is, a worker status display area (521) in which the worker's status is displayed, and a risk factor display area (522) in which the presence of a risk factor is displayed, may be located within the notification area (520).

[0242] The worker can touch the notification area (520) of the site using a finger or tool to check detailed information about the hazards of the site where the worker is deployed.

[0243] The first terminal (231) can transmit a signal requesting risk information of the site to the safety management server (101) according to the input of the worker.

[0244] The safety management server (101) can transmit the requested risk information of the corresponding site to the first terminal (231) (S32).

[0245] The risk information management device (120) can receive a signal requesting risk information of a corresponding site from the first terminal (231). The risk information management device (120) can transmit the requested risk information of the corresponding site from among the risk information stored in the risk information storage device (110) to the first terminal (231). For example, the signal transmitted by the first terminal (231) to the safety management server (101) can include identification information that can identify the corresponding site. In addition, the risk information management device (120) can identify the requested risk information of the corresponding site from among numerous pieces of information stored in the risk information storage device (110) through the identification information included in the received signal and transmit the information to the first terminal (231).

[0246] The first terminal (231) can output the risk information of the corresponding site received from the safety management server (101) (S33).

[0247] The first terminal (231) can output the risk information of the site received from the safety management server (101) through a screen so that the worker can visually check it.

[0248] The worker can check detailed descriptions of the risk factors at the site through the risk information displayed on the screen of the first terminal (231). Figures 4 and 5 are drawings illustrating a method for checking risk information at the site through the application of the first terminal (231).

[0249] Figure 4 is an example diagram showing the risk items of the corresponding site displayed on the screen of the first terminal (231).

[0250] Referring to FIG. 4, risk items may include major risk items (610) and location-specific risk items (620).

[0251] The major risk items (610) may list the major risk factors of the site. Here, the major risk factors are risk factors that occur frequently at the site, regardless of the area or location. In other words, the major risk items (610) may be risk factors caused by devices or structures that are commonly included in each area of ​​the site. Here, the areas of the site may be parts that make up the elevator, such as the elevator pit, platform, elevator shaft, cage, and machine room, as well as parts that make up the elevator. For example, the major risk items (610) may include risk factors such as a lighting short circuit or loose fixing of a structure.

[0252] Additionally, the location-specific risk items (620) may be risk factor items that occur at each location.

[0253] For example, the location-specific risk items (620) may include major risk items (610), and the major risk items (610) may be separated by location in the field.

[0254] Even for the risk factors included in the major risk items (610), the methods for eliminating or preventing risks caused by the risk factors may vary depending on the location. For example, the location of lighting, illumination, and power supply methods may vary depending on the inside of the cage, the machine room outside the cage, the platform, and the pit. Accordingly, the location-specific risk items (620) may include risk factors for each location in the site and safety measures for each risk factor. Here, safety measures are methods for resolving risks, such as preventing or eliminating risks that may arise from the risk factors.

[0255] Additionally, location-specific risk items are not included in the main risk items (610), and may include risk factors and risk resolution methods for devices and structures installed in each area. For example, location-specific risk items (620) may be categorized into machine rooms, platforms, elevator shafts, pits, and cages, and each location item may include risk factors and corresponding safety measures. Workers can prepare to ensure safety from the corresponding risk factors through safety measures.

[0256] Referring to Figure 4, risk information may include audiovisual information (630) that allows visual confirmation of risk factors registered in the application through the screen of the first terminal (231). The audiovisual information (630) may be a photograph or video that allows visual and auditory confirmation of the status of the risk factors registered in the risk information. Through the audiovisual information (630), workers can more accurately confirm the status of the risk factors.

[0257] Figure 5 is an example diagram showing audiovisual information (630) of a risk factor displayed on the screen of the first terminal (231).

[0258] Referring to Fig. 5, audiovisual information (630) can be checked through the screen of the first terminal (231). If the risk information of the site includes multiple audiovisual information (630), the worker can select the desired audiovisual information (630) and check the corresponding risk factor. The worker can accurately determine the location, shape, status, etc. of the risk factor through the audiovisual information (630). In addition, the audiovisual information (630) can be enlarged or reduced according to the worker's adjustment. For example, the worker can enlarge or reduce the screen on which the audiovisual information (630) is displayed using a finger or a tool. Therefore, the worker can check the information on the risk factor more accurately.

[0259] The worker can transmit the screen of the first terminal (231) to the second terminal (232). The second terminal (232) can share the screen of the first terminal (232) and output it to a display.

[0260] The worker can select the share button (640) through the screen of the first terminal (231) illustrated in Fig. 4. When the first terminal (231) receives a share signal through the share button (640), it can transmit the risk information displayed on the screen to the second terminal (232).

[0261] FIG. 13 is a simplified exemplary diagram illustrating a second terminal (232) according to an embodiment of the present invention.

[0262] Referring to FIG. 13, the second terminal (232) may be in the form of glasses and include a display unit (205), a support unit (206), and a mounting unit (207).

[0263] The display unit (205) displays risk information received from the first terminal (231) and may be a transparent display that does not obstruct the worker's view.

[0264] Referring to FIG. 13, the screen of the first terminal (101) may be displayed on a portion (A) of the display unit (205) of the second terminal (232). That is, the same screen as the screen of the first terminal (101), including the design and risk information of the application, may be output on a portion of the second terminal (232). However, the way in which the second terminal (232) is displayed on the display unit (205) is not limited to the way in which the screen of the first terminal (231) is shared. For example, the first terminal (231) may transmit or share only the risk information excluding the design of the application displayed on the screen to the second terminal (232). Accordingly, only the location, description, safety measures, photos, and videos of risk factors may be displayed on the display unit (205) of the second terminal (232). In this case, the size of the area displaying risk information on the display unit (205) of the second terminal (232) can be minimized to minimize the operator's field of vision obstruction, and the risk to the operator due to field of vision obstruction can be reduced.

[0265] The support member (206) can serve to support the display member (205). In addition, the support member (205) can fix the display member (205) to the mounting member (207).

[0266] The mounting part (207) can be mounted on the worker's body. The second terminal (232) can be fixed to the worker's body by the mounting part (207).

[0267] According to an embodiment of the present invention, when the second terminal (232) is secured by the mounting portion (207) around the worker's ear, the display portion (205) can be positioned in front of the worker's eyes. Accordingly, the worker can check the risk information displayed on the display portion (205). In addition, the worker can perform management tasks while checking the risk information for the corresponding site or by site location.

[0268] In addition, the second terminal (232) may additionally include an audio output unit (211) in addition to the display unit (205) so that the worker can check the risk information. For example, the audio output unit (211) may be a speaker formed on the inner surface of the mounting unit (207) of the second terminal (232). When the worker wears the second terminal (232), the speaker formed in the mounting unit (207) may be positioned near the worker's ear. The worker may hear the content of the risk information in voice or hear an alarm about the risk information through the speaker, which is the audio output unit (211). As another example, the audio output unit (211) may be in the form of an earphone that is connected to a part of the second terminal (232) and can be worn on the worker's ear when the worker wears the second terminal (232).

[0269] In addition, when the information access authority authentication of the safety management server (101) is completed, the second terminal (232) can transmit a signal requesting risk information to the first terminal (231). To this end, the second terminal (232) can include at least one of a voice recognition unit (212) and a button (213). For example, the voice recognition unit (212) can be a microphone formed at the bottom of the mounting unit (207). Therefore, when a worker wears the second terminal (232), the voice recognition unit (212) can receive the worker's voice. In addition, the button (213) can be formed on the outer surface of the mounting unit (207) so that the worker can easily touch or press it with a finger while wearing the second terminal (232). Therefore, the worker can send a signal requesting risk information to the first terminal (231) by voice using the voice recognition unit (212) of the second terminal (232) that the worker is wearing. Alternatively, the worker can press the button (213) of the second terminal (232) being worn to send a signal requesting risk information to the first terminal (231).

[0270] The terminal (230) according to the embodiment of the present invention includes a first terminal (231) that searches for risk information, a second terminal (232) that shares risk information with the first terminal (232), and outputs the shared risk information through at least one of a screen and voice so that the worker can immediately check it, thereby enabling the worker to continuously be aware of risk factors at the site.

[0271] In addition, the second terminal (232) may store the changed risk information or store it in the safety management server (101) through the first terminal (231). Here, the changed risk information may include new risk information, which is information on new risk factors, and information changed from previous risk information. For example, the worker may store the changed risk information as a voice through the voice recognition unit (212) of the second terminal (232) or transmit it to the first terminal (231) and store it. Alternatively, the second terminal (232) may additionally include a camera (214). In this case, the worker may store the changed risk information as a video or photo through the camera (214) of the second terminal (232) or transmit it to the first terminal (231) and store it.

[0272] As another example, risk information may further include identification information that can identify the risk factor. For example, the identification information may include the location, structure, product information, etc. of the risk factor. In this case, the second terminal (232) may display the risk factor if it is located within the worker's field of vision using the identification information. This can be done in various ways, such as displaying an arrow pointing to the risk factor or displaying the risk factor in a different color to distinguish it from its surroundings.

[0273] Through steps S31 (S31) to S34 (S34) of FIG. 12, the worker can check the risk information of the site in advance before arriving at the site using the first terminal (231).

[0274] Before departing for a site, workers can review information about hazards and, based on this information, prepare the necessary equipment to eliminate or prevent hazards. This means workers can bring not only equipment for elevator maintenance and repairs, but also equipment necessary to eliminate hazards. Therefore, workers can not only perform requested repairs or regular maintenance inspections, but also eliminate hazards that may have arisen on site. For example, if the hazard is a component failure, workers can repair the broken part to eliminate the hazard. Furthermore, if the hazard is electric shock from a component, workers can avoid touching the component or wear insulated gloves when performing requested maintenance tasks to prevent electric shock.

[0275] While performing maintenance and other management tasks at a site, workers can discover new information about the site's hazards. Workers can transmit this new information to the safety management server (101) via an application on the first terminal (231).

[0276] The first terminal (231) can receive new risk information at the site (S35).

[0277] New risk information may include information that differs from the previously registered risk information for the site. For example, new risk information may include information about hazards newly discovered by workers at the site and those likely to become hazards in the future. New risk information may also include information about hazards that have already been eliminated or eliminated by current workers. Furthermore, new risk information may include information that has been modified from previous risk information.

[0278] For example, while managing the site, the worker may discover a new risk factor that is not registered in the risk information confirmed through the first terminal (231) or the second terminal (232). Alternatively, the worker may check changed information about the risk factor confirmed through the first terminal (231) or the second terminal (232). At this time, the worker may register changed information about the new risk factor or the previous risk factor to the safety management server (101) through the application of the first terminal (231). In addition, while managing the site, the worker may register information about factors that may become risk factors during future site management to the safety management server (101) through the application of the first terminal (231).

[0279] Alternatively, when a worker discovers a new hazard, he or she can record information about the new hazard by voice using the voice recognition unit (212) of the second terminal (232) or capture it as a photo or video using the camera (214). The second terminal (232) can transmit the new hazard information recorded as at least one of voice, photo, and video to the first terminal (231). The first terminal (231) can register the new hazard information received from the second terminal (232) to the safety management server (101) through an application.

[0280] Additionally, if there is a change in the previous risk information, the worker may transmit the changed information to the safety management server (101) via the first terminal (231) or the second terminal (232).

[0281] [Example of registering new risk information using a terminal]

[0282] Figures 6 to 9 are drawings for explaining a method for registering new risk information through an application of the first terminal (231).

[0283] Figure 6 is a start screen for registering new risk information displayed on the terminal screen.

[0284] Referring to FIG. 6, a worker can register new risk information by executing an application on the first terminal (231) and writing a work log displayed on the screen of the first terminal (231). Here, registering new risk information means adding new risk information to previous risk information or deleting or changing some of the risk information already registered.

[0285] The worker can select the risk factor management item (710) from the screen of the first terminal (231) of FIG. 6.

[0286] Figure 7 is an example of the screen of the first terminal (231) displayed when a worker selects a risk factor management item (710).

[0287] The worker can select a major risk factor item (810) or a location-specific risk factor item (820) from among the risk factor management items (710). The worker can register a risk factor by selecting only one of the major risk factor item (810) and the location-specific risk factor item (820). Alternatively, the worker can register a risk factor in both the major risk factor item (810) and the location-specific risk factor item (820).

[0288] FIG. 8 is an example of a screen output on the first terminal (231) when the main risk factor item (810) of FIG. 7 is selected. Referring to FIG. 8, a list (811) of main risk factors may be output on the screen of the first terminal (231). Here, the outputted main risk factors may be risk factors that commonly occur regardless of location or risk factors that frequently occur statistically. At this time, among the outputted list (811) of main risk factors, the list with the checkboxes already checked is a risk factor that has already been discovered and registered on the safety management server (101).

[0289] The worker can select one or more risk factors corresponding to new risk factors from the major risk factors displayed on the screen of the first terminal (231). Furthermore, if there are no risk factors corresponding to new risk factors among the list displayed on the screen of the first terminal (231), the worker can also directly record information about the new risk factor.

[0290] Figure 9 is an example of a screen displayed on the first terminal (231) when a location-specific risk item (620) of Figure 7 is selected.

[0291] Among the risk items (620) by location in Figure 7, the worker can select the location of a new risk factor. For example, the location of the new risk factor may be a machine room. If the worker selects a machine room, the first terminal (231) may display the screen of Figure 9.

[0292] Referring to Figure 9, a list of risk factors can be output for each location within the site. When a worker selects the location of a new risk factor, a list of risk factors for that location can be output on the screen of the first terminal (231). For example, if the worker selects a machine room, a list of risk factors for that machine room can be output on the screen of the first terminal (231).

[0293] The worker can select one or more risk factors corresponding to a new risk factor from the list displayed on the screen of the first terminal (231). For example, a new risk factor can be added by checking the checkbox of a risk factor corresponding to a new risk factor in the list of risk factors.

[0294] Additionally, if there is no risk factor corresponding to a new risk factor among the list displayed on the screen of the first terminal (231), the worker can directly record information on the new risk factor by location.

[0295] Additionally, when a worker selects a location for a new hazard, the list of hazards at that location is not the only thing displayed on the screen of the first terminal (231). For example, when a worker selects a location for a new hazard, a list of hazards at the selected location may be displayed in the central area of ​​the screen of the first terminal (231). At this time, the worker can simultaneously check the list of hazards at other locations as well as the selected location by adjusting the screen of the first terminal (231) using a finger or tool.

[0296] Additionally, the worker can add audiovisual information (830) on new risk factors for each site through the first terminal (231).

[0297] Additionally, when the worker arrives at the site, at least some of the risk factors registered in the safety management server (101) may have been removed. Alternatively, at least some of the risk factors registered in the safety management server (101) may be removed through the worker's management tasks. In this case, the worker may delete information about the removed risk factors from the safety management server (101) through the application of the first terminal (231).

[0298] The operator can delete information about previously registered risk factors that have been removed from the list of major risk factors (810) and location-specific risk factors (820). For example, in FIGS. 8 and 9 , check boxes already checked in the list of major risk factors (811) and location-specific risk factors (821) are previously registered risk factors. Removal of a risk factor can be accomplished by unchecking the checkbox of the risk factor.

[0299] Additionally, the worker can remove audiovisual information (830) of the removed hazard.

[0300] In the embodiment of the present invention, adding or deleting a risk factor to an application of the first terminal (231) is performed by checking or unchecking the checkbox for the corresponding risk factor. However, the present invention is not limited to this. That is, various methods can be used to input new risk information into the first terminal (231).

[0301] The worker can input new risk information including information that adds a risk factor to the application of the first terminal (231) or deletes a previous risk factor and select transmit on the screen of FIG. 6.

[0302] When the first terminal (231) receives a transmission signal, it can transmit new risk information of the corresponding site to the safety management server (101) (S36).

[0303] The safety management server (101) can update new risk information received from the first terminal (231) to the information storage device (S37).

[0304] The risk information management device (120) can compare the previous risk information stored in the risk information storage device (110) with the new risk information received from the first terminal (231) and apply the changes to the previous risk information.

[0305] Through this process, when the safety management server (101) updates the risk information of the site, the safety management stage of the safety management system (30) can be terminated.

[0306] Additionally, the first terminal (231) may not receive new risk information (S35).

[0307] If the first terminal (231) does not receive new risk information, the safety management stage of the safety management system (30) may also be terminated.

[0308] Although the embodiment of the present invention describes that the step of receiving new risk information by the first terminal (231) is performed after the step of outputting risk information of the corresponding site by the first terminal (231), the present invention is not limited thereto. For example, if risk information of the corresponding site does not exist, the step of receiving new risk information by the first terminal (231) may be performed before or after the step of requesting risk information from the safety management server (101). In addition, in this case, the risk information management device (120) may store the received new risk information as risk information of the corresponding elevator in the risk information storage device (110).

[0309] According to the safety management system (30) and safety management method according to the embodiment of the present invention, workers deployed to a site for regular maintenance or repair can identify risk factors at the site in advance. Therefore, workers can prepare for risks that may occur at the site. For example, workers can prepare equipment to remove risk factors at the site and remove them at the site. In addition, workers can prevent the occurrence of risks by identifying the location and status of risk factors that may occur at the site. Therefore, the safety management system (30) and safety management method according to the embodiment of the present invention enable workers to identify risk factors at the site in advance and efficiently establish site management plans. In addition, the safety management system (30) and safety management method according to the embodiment of the present invention can improve the safety of on-site work, and thus, work efficiency.

[0310] For example, while inspecting a machine room, a worker may discover a connector with damaged wire insulation, exposing the inner conductor. In this case, the worker can register the risk factor as "Machine Room → Risk of Electric Shock" through the application on his / her first terminal (231). At this time, the worker can attach a photo showing the condition of the risk factor through the application on his / her first terminal (231) and also register safety measures such as "Insulation measures required." Afterwards, the next worker of the elevator can recognize the risk factor in the machine room in advance through his / her first terminal (231) or second terminal (232), prepare safety equipment such as insulating gloves in advance, and safely perform the task.

[0311] As another example, a worker may be aware of a falling hazard by discovering a box of parts not secured to the upper portion of a hoistway during an inspection. In this case, the worker can select "Hoistway" from the risk categories by location through an application on their first terminal (231) and register the item "Risk of Falling Temporary Parts Fixtures." This item may include a photo, the location of the hazard, the time of occurrence, and a response plan. Subsequently, the worker can preemptively identify areas at risk of falling objects through their first terminal (231) or second terminal (232) and take safety measures, such as wearing protective gear and ensuring the parts are secured during work.

[0312] In all of the examples described above, the worker carries a first terminal (231) connected to a safety management server and a second terminal (232) that shares risk information with the first terminal (231) and displays the information. By wearing the second terminal (232), which is configured as a display in the form of glasses, the worker can simultaneously check risk information without obstructing their field of vision and perform management tasks. Furthermore, the worker can accurately identify the location of risk factors within their field of vision through the second terminal (232), enabling them to quickly recognize risk factors or quickly perform tasks to resolve them.

[0313] [Configuration of the safety management system according to the fourth embodiment]

[0314] Figure 14 is a block diagram showing a safety management system according to a fourth embodiment of the present invention.

[0315] The safety management system (40) according to the fourth embodiment may include a terminal (230) and a safety management server (102). In addition, referring to FIG. 14, the safety management server (102) may include a risk information storage device (110), a risk information management device (120) that analyzes risk information, and a risk notification device (130) that sends a risk warning to a worker's terminal (230). The terminal (230), the risk information storage device (110), and the risk information management device (120) of the safety management system (40) of the present embodiment are identical to the terminal (230), the risk information storage device (110), and the risk information management device (120) of the safety management system (30) of the third embodiment of FIG. 11. Therefore, for a detailed description of the terminal (230), the risk information storage device (110), and the risk information management device (120) of the present embodiment, refer to the previous description. In addition, the description of the safety management system (40) of the present embodiment will be centered on the risk notification device (130) that is different from the safety management system of the third embodiment (30 of FIG. 11).

[0316] The risk notification device (130) of the safety management system (40) of this embodiment can transmit risk information to the worker's first terminal (231) before the worker enters the site.

[0317] When a worker is deployed to a site for maintenance and repair, information about the worker deployed to the site can be entered and stored in the safety management server (102) by the manager. Here, the worker information may include information about not only the worker but also the worker's first terminal (231). Furthermore, the manager may be the person who deploys the worker to the site requiring maintenance and repair. Alternatively, the manager may be a program or system that automatically deploys the worker to the site requiring maintenance and repair.

[0318] For example, a manager can transmit site information and information on workers deployed at the site to a risk information management device (120) of a safety management server (102). The risk information management device (120) can check whether risk information for the corresponding site is stored in the risk information storage device (110) based on the received site information. If risk information for the corresponding site exists in the risk information storage device (110), the risk information management device (120) can transmit a signal to a risk notification device (130).

[0319] When the risk notification device (130) receives a signal from the risk information management device (120), it can transmit a risk notification signal to the first terminal (231) of a worker deployed at the site. More specifically, the risk notification device (130) can receive information about the site and the worker deployed at the site through the signal received from the risk information management device (120) and transmit a risk notification signal to the first terminal (231) of the worker.

[0320] When the worker's first terminal (231) receives a risk notification signal from the risk notification device (130) of the safety management server (102), it can output a risk alarm so that the worker can check the risk information. The risk alarm of the first terminal (231) can be performed in various ways, such as an alarm, vibration, or light of the first terminal (231).

[0321] In addition, the first terminal (231) can transmit the received hazard notification signal to the second terminal (232). When the second terminal (232) receives the hazard notification signal from the first terminal (231), it can output a hazard alarm so that the worker can check the hazard information. The hazard alarm of the second terminal (232) can be output as text on the display unit (205 of FIG. 13). Therefore, if the worker is wearing the second terminal (232), he / she can immediately know that hazard information exists at the site.

[0322] In addition, the risk alarm device (130) transmits a risk notification signal to the first terminal (231) and the second terminal (232) simultaneously, and the first terminal (231) and the second terminal (232) can each output a risk alarm when receiving the risk notification signal.

[0323] For example, a worker may be deployed to a machine room for regular inspection. The risk information management device (120) may retrieve information about electric shock hazards registered in the machine room from information stored in the risk information storage device (110).

[0324] The hazard notification device (130) transmits a hazard notification signal, which is a warning signal corresponding to the corresponding hazard, to the worker's first terminal (231). The first terminal (231) can share the hazard notification signal by transmitting it to the second terminal (232) worn by the worker in the form of glasses. The second terminal (232) can immediately notify the worker of the hazard by displaying a warning message on a portion of the display so as not to obstruct the worker's field of vision.

[0325] Accordingly, the worker can check the warning message automatically displayed through the second terminal (232) worn on the body without having to take out the first terminal (231) carried in the work uniform pocket or bag and check the screen to check the warning message.

[0326] Workers can recognize potential electric shock hazards, such as damaged wire insulation, before entering the work site through the corresponding warning message automatically output from the second terminal (232). By preparing insulating gloves or mats in advance, workers can ensure safety during work. Furthermore, workers can accurately identify the location of hazards through the second terminal (232), thereby enhancing safety during work.

[0327] In this way, the safety management system (40) according to the fourth embodiment of the present invention enables advance prevention by actively notifying workers of risk factors before they enter the site.

[0328] As such, the safety management system (40) of the present embodiment can notify workers of the presence of risk information (risk factors) at the relevant site in advance, before the worker requests risk information. Therefore, the step in which the safety management system (40) notifies workers of the risk information at the relevant site via the first terminal (231) may be performed before the step in which the first terminal (231) requests risk information from the safety management server (102) among the steps of the safety management method of FIG. 12.

[0329] The safety management system (40) and safety management method according to this embodiment can notify workers in advance of the presence of hazards at a site, allowing them to search for information about the hazards at the site and prepare for them. Therefore, the safety management system (40) and safety management method according to this embodiment can ensure that workers are aware of the risks and perform their management tasks safely.

[0330] [Configuration of the safety management system according to the fifth embodiment]

[0331] Figure 15 is a block diagram showing a safety management system according to a fifth embodiment of the present invention.

[0332] The safety management system (50) and safety management method according to an embodiment of the present invention are intended to ensure the safety of workers from risks that may occur at a site where an elevator is managed.

[0333] Referring to FIG. 15, a safety management system (50) according to an embodiment of the present invention may include a terminal (200) and a safety management server (101).

[0334] The safety management server (101) is connected to a terminal (200) and can collect information on risk factors from the terminal (200). Furthermore, the safety management server (101) can monitor risk factors at each site using the collected risk information. Furthermore, according to the present embodiment, the safety management server (101) can be connected to at least one terminal (200). Here, the site may be the interior or exterior of an elevator cage where workers are stationed and require management. Here, management and maintenance tasks refer to all actions performed by workers for the maintenance and upkeep of the elevator. For example, management and maintenance tasks may include regular inspections for elevator maintenance and repairs to resolve elevator malfunctions.

[0335] Referring to FIG. 15, the safety management server (101) may include a risk information storage device (110) and a risk information management device (120) that analyzes risk information.

[0336] The risk information storage device (110) can store risk information collected for each site. Risk information is information on risk factors discovered by previous workers at each site. Risk factors can be anything that could pose a risk to workers when performing elevator maintenance work inside or outside the elevator. For example, a risk factor can be any component, structure, or object located inside or outside the elevator that threatens the safety of workers. Furthermore, risk information can include any information related to risk factors, such as the location or status of the risk factor, the time of occurrence or discovery of the risk factor, and the method of handling the risk factor.

[0337] The risk information management device (120) can manage information about risk factors received from the terminal (200). For example, the risk information management device (120) can transmit the risk information received from the terminal (200) to the risk information storage device (110). Here, the risk information can include initial risk information for the corresponding site and new risk information that includes information different from previous risk information. In addition, the risk information management device (120) can update the risk information storage device (110) with the new risk information received from the terminal (200). For example, the new risk information can be information different from the risk information previously stored in the risk information storage device (110). Therefore, the safety management system (50) can reflect the new risk information received from the terminal (200) into the risk information stored in the risk information storage device (110) to monitor the risk factors and risk environment of each site in real time.

[0338] Although the risk prediction device (301) is not included in the risk information, it can predict risk factors with a high probability of occurring at each site based on various past risk information.

[0339] A risk prediction method of a safety management system according to an embodiment of the present invention is described with reference to FIGS. 15 and 16.

[0340] The risk prediction device (301) may include a learning information collection unit (310) and a risk prediction unit (320). The learning information collection unit (310) collects learning information necessary for the risk prediction device (301) to learn risk prediction, and the risk prediction unit (320) may analyze the learning information to generate risk prediction information.

[0341] First, the learning information collection unit (310) can collect and store learning information (S51).

[0342] Learning information may include site information for each elevator within the management target and information on past hazards at each site. Site information may include detailed information, such as the elevator's unique number, location, and installation date, for each site.

[0343] The risk information storage device (110) of the safety management server (101) stores updated risk information for each site. However, the learning information collection unit (310) can collect all past risk information for the site transmitted via the terminal (200). In this way, the learning information collection unit (310) can collect and store all history related to risk factors occurring at each site.

[0344] The risk prediction unit (320) can analyze learning information to generate common risk information (S52).

[0345] The risk prediction unit (320) can classify only information on natural hazards that may arise from the aging of the elevator, the installation environment, and natural disasters among all the learning information collected by the learning information collection unit (310). For example, the aging of the elevator may cause a step difference on the platform, which may cause workers to fall when boarding or alighting the car. Furthermore, if the insulation of the electrical devices in the machine room is poor due to the aging of the elevator, a control panel error may cause the car door to malfunction, resulting in a power outage or trapping workers inside the car. Furthermore, if rainwater flows into the machine room or car due to a natural disaster such as heavy rain, safety hazards such as power outages, door malfunctions, and slipping may occur. Furthermore, the elevator installation environment, such as the aging of the building, may cause rainwater to flow into the machine room or car, resulting in safety hazards. Furthermore, weather conditions such as high temperatures and high humidity may expose workers to danger due to control panel errors in the machine room.

[0346] In addition, the risk prediction unit (320) can analyze site information according to the classified natural risk factors. The risk prediction unit (320) can extract common risk information by analyzing the date on which the common risk factor occurred at the site, the cause of occurrence, and detailed information of the site information based on common risk factors, which are identical risk factors. That is, the common risk information can include common risk factors, safety measures to resolve the risk caused by the common risk factor, and common detailed items that are the same detailed items between sites where each common risk factor occurred. For example, the risk prediction unit (320) can generate common risk information that includes information such as risk factors that commonly occur depending on the degree of aging of the elevator, risk factors that commonly occur depending on the installation environment, risk factors that commonly occur depending on natural disasters, and risk factors that commonly occur when at least two of the aging of the elevator, the installation environment, and the natural disaster overlap.

[0347] Additionally, the risk prediction unit (320) can compare common risk information, field information, and risk information stored in the risk information storage device (110) of the safety management server (101).

[0348] The risk prediction unit (320) can compare common details of common risk information with field information of all fields and classify field information having details corresponding to common details (S53).

[0349] Through this, the risk prediction unit (320) can classify sites where common risk factors may occur among all sites managed by the safety management system (50).

[0350] The risk prediction unit (320) can search for classified on-site risk information among the risk information stored in the risk information storage device (110).

[0351] Additionally, the risk prediction unit (320) can compare the risk information of the classified site with common risk information (S54).

[0352] The risk prediction unit (320) can generate risk prediction information based on the comparison results and transmit the generated risk prediction information to the safety management server (101) (S55).

[0353] The risk prediction unit (320) can generate risk prediction information if there is no risk information of the site classified in the risk information storage device (110).

[0354] In addition, the risk prediction unit (320) can generate risk prediction information if there is risk information of an elevator classified in the risk information storage device (110), but the risk information does not include a common risk factor of the common risk information.

[0355] The risk prediction unit (320) can transmit the generated risk prediction information to the safety management server (101).

[0356] Additionally, the risk prediction unit (320) does not generate risk prediction information if the risk information of the classified site includes all common risk factors of the common risk information.

[0357] The risk information management device (120) of the safety management server (101) can create or update risk information of the corresponding site by reflecting the received risk prediction information (S56).

[0358] The terminal (200) is a device that allows workers performing elevator maintenance work to input information about hazards discovered on-site or to check information about hazards at the site before arriving at the site. For example, the terminal (200) can transmit hazard information entered by the worker to the safety management server (101). In addition, the terminal (200) can receive hazard information at the site from the safety management server (101) and display it on the screen for the worker to check.

[0359] The safety management system (50) of an embodiment of the present invention may include a plurality of terminals (200). The plurality of terminals (200) are devices connected to the safety management server (101) via a communication network and capable of displaying information on a screen or through sound so that a user can input information or confirm the results of information processing visually or audibly. The plurality of terminals (200) may be any device equipped with an application capable of transmitting and receiving information to and from the safety management server (101).

[0360] The plurality of terminals (200) may all be devices of the same type, each having an application installed that connects to the safety management server (101). Alternatively, the plurality of terminals (200) may be devices of different types, each having an application installed that connects to the safety management server (101). In this way, the plurality of terminals (200) may be any device that has an application installed that connects to the safety management server (101) and can transmit and receive risk information to the safety management server (101) through the installed application.

[0361] The operation of the safety management system (50) according to an embodiment of the present invention will be described in detail through an embodiment of the following safety management method.

[0362] [Example of the operation sequence and usage method of the safety management system according to the fifth embodiment]

[0363] Figure 17 is a flowchart illustrating a safety management method of a safety management system according to a fifth embodiment of the present invention. The safety management method of the safety management system according to the fifth embodiment of Figure 17 is described with reference to example diagrams of applications displayed on the screen of the worker's terminal of Figures 3 to 9.

[0364] The safety management method according to the fifth embodiment of FIG. 17 can be implemented through the safety management system (50) of FIG. 15.

[0365] A worker performing elevator maintenance may be deployed to the site where the elevator is located when elevator maintenance, such as elevator breakdown repair or regular inspection, is required.

[0366] The safety management method of the safety management system (50) can be initiated when a worker is deployed to a site requiring breakdown repair or regular inspection through a terminal (200) or other device.

[0367] First, the terminal (200) can request risk information from the safety management server (101) (S61).

[0368] When a worker is deployed to a site, the worker can request risk information of the site to the safety management server (101) through an application installed on the terminal (200).

[0369] Figure 3 is an example of a screen displayed on a terminal (200) when an application installed on the terminal (200) is executed. When a worker executes an application installed on the terminal (200), a site list (510) listing sites where the worker is assigned or managed may be displayed on the screen of the terminal (200).

[0370] The site list (510) may display brief information, such as the name, address, and last inspection date of each site. Additionally, the site list (510) may display information indicating the worker status for each site. Here, the worker status may be information regarding the worker's current status, such as whether the worker has left the site, whether maintenance work is in progress, or whether maintenance work has been completed.

[0371] The site list (510) may indicate whether or not a risk factor exists at each site. The presence of a risk factor may be indicated in various ways, such as by color, text, or pictures.

[0372] For example, the screen output through the application may include a notification area (520), and the notification area (520) may display the worker's status and the presence of a risk factor, as illustrated in FIG. 3. The notification area (520) may indicate the presence of a risk factor at the site with a border color and text. For example, if a risk factor exists at the site, the border of the notification area (520) may be displayed in red, and risk factor text may be displayed within the notification area (520). Furthermore, the red border of the notification area (520) may blink in order to clearly inform the worker of the presence of the risk factor. That is, a worker status display area (521) in which the worker's status is displayed, and a risk factor display area (522) in which the presence of a risk factor is displayed, may be located within the notification area (520).

[0373] The worker can touch the notification area (520) of the site using a finger or tool to check detailed information about the hazards of the site where the worker is deployed.

[0374] The terminal (200) can transmit a signal requesting risk information of the site to the safety management server (101) according to the input of the worker.

[0375] The safety management server (101) can transmit the requested risk information of the corresponding site to the terminal (200) (S62).

[0376] The risk information management device (120) can receive a signal requesting risk information of a corresponding site from the terminal (200). The risk information management device (120) can transmit the requested risk information of the corresponding site from among the risk information stored in the risk information storage device (110) to the terminal (200). For example, the signal transmitted by the terminal (200) to the safety management server (101) can include identification information that can identify the corresponding site. In addition, the risk information management device (120) can identify the requested risk information of the corresponding site from among numerous pieces of information stored in the risk information storage device (110) through the identification information included in the received signal and transmit the information to the terminal (200).

[0377] The terminal (200) can output the risk information of the corresponding site received from the safety management server (101) (S63).

[0378] The terminal (200) can output the risk information of the site received from the safety management server (101) through a screen so that the worker can visually check it.

[0379] The worker can check detailed descriptions of the risk factors at the site through the risk information displayed on the screen of the terminal (200). Figures 4 and 5 are drawings explaining a method for checking risk information at the site through an application of the terminal (200).

[0380] Figure 4 is an example diagram showing the risk items of the corresponding site displayed on the terminal (200) screen.

[0381] Referring to FIG. 4, risk items may include major risk items (610) and location-specific risk items (620).

[0382] The major risk items (610) may list the major risk factors of the site. Here, the major risk factors are risk factors that occur frequently at the site, regardless of the area or location. In other words, the major risk items (610) may be risk factors caused by devices or structures that are commonly included in each area of ​​the site. Here, the areas of the site may be parts that make up the elevator, such as the elevator pit, platform, elevator shaft, cage, and machine room, as well as parts that make up the elevator. For example, the major risk items (610) may include risk factors such as a lighting short circuit or loose fixing of a structure.

[0383] Additionally, the location-specific risk items (620) may be risk factor items that occur at each location.

[0384] For example, the location-specific risk items (620) may include major risk items (610), and the major risk items (610) may be separated by location in the field.

[0385] Even for the risk factors included in the major risk items (610), the methods for eliminating the risk factors or preventing the risks caused by the risk factors may vary depending on the location. For example, the lighting placement location, illumination intensity, and power supply method may vary depending on the inside of the cage, the machine room outside the cage, the platform, and the pit. Accordingly, the location-specific risk items (620) may include the risk factors for each location in the site and safety measures for each risk factor. Here, safety measures are methods for resolving the risks caused by the risk factors, such as preventing or eliminating the risk factors that may arise from the risk factors.

[0386] Additionally, location-specific risk items are not included in the main risk items (610), and may include risk factors and risk resolution methods for devices and structures installed in each area. For example, location-specific risk items (620) may be categorized into machine rooms, platforms, elevator shafts, pits, and cages, and each location item may include risk factors and corresponding safety measures. Workers can prepare to ensure safety from the corresponding risk factors through safety measures.

[0387] Referring to FIG. 4, risk information may include audiovisual information (630) that allows visual confirmation of risk factors registered in the application through the terminal (200) screen. The audiovisual information (630) may be a photograph or video that allows visual and auditory confirmation of the status of the risk factors registered in the risk information. Through the audiovisual information (630), workers can more accurately confirm the status of the risk factors.

[0388] Figure 5 is an example diagram showing audiovisual information (630) of a risk factor displayed on the screen of a terminal (200).

[0389] Referring to Fig. 5, audiovisual information (630) can be checked through the screen of the terminal (200). If the risk information of the site includes multiple audiovisual information (630), the worker can select the desired audiovisual information (630) and check the corresponding risk factor. The worker can accurately determine the location, shape, status, etc. of the risk factor through the audiovisual information (630). In addition, the audiovisual information (630) can be enlarged or reduced according to the worker's adjustment. For example, the worker can enlarge or reduce the screen on which the audiovisual information (630) is displayed using a finger or a tool. Therefore, the worker can check the information on the risk factor more accurately.

[0390] Through steps S51 (S51) to S53 (S53) of FIG. 17, the worker can check the risk information of the site in advance before arriving at the site using the terminal (200).

[0391] Before departing for a site, workers can review information about hazards and, based on this information, prepare the necessary equipment to eliminate or prevent hazards. This means workers can bring not only equipment for elevator maintenance and repairs, but also equipment necessary to eliminate hazards. Therefore, workers can not only perform requested repairs or maintenance routines, but also eliminate hazards that may have arisen on site. For example, if the hazard is a component failure, workers can repair the broken part to eliminate the hazard. Furthermore, if the hazard is electric shock from a component, workers can avoid touching the component or wear insulated gloves when performing requested maintenance tasks to prevent electric shock.

[0392] While performing maintenance and management tasks at a site, workers can discover new information about the site's hazards. Workers can transmit this new information to the safety management server (101) via an application on their terminal (200).

[0393] The terminal (200) can receive new risk information at the site (S64).

[0394] New risk information may include information that differs from the previously registered risk information for the site. For example, new risk information may include information on hazards newly discovered by workers at the site and those likely to become hazards in the future. Additionally, new risk information may include information on hazards that have already been eliminated or eliminated by current workers.

[0395] For example, while managing a site, a worker may discover a new risk factor that is not registered in the risk information confirmed through the terminal (200). At this time, the worker may register information about the new risk factor to the safety management server (101) through the application of the terminal (200). In addition, while managing the site, the worker may register information about factors that may become risk factors during future site management to the safety management server (101) through the application of the terminal (200).

[0396] [Example of registering new risk information using a terminal]

[0397] Figures 6 to 9 are drawings for explaining a method for registering new risk information through an application of a terminal (200).

[0398] Figure 6 is a start screen for registering new risk information displayed on the terminal screen.

[0399] Referring to FIG. 6, a worker can register new risk information by executing an application on a terminal (200) and writing a work log displayed on the screen of the terminal (200). Here, registering new risk information means adding new risk information to previous risk information or deleting or changing some of the risk information already registered.

[0400] The worker can select a risk factor management item (710) from the screen of the terminal (200) of Fig. 6.

[0401] Figure 7 is an example of a screen of a terminal (200) displayed when a worker selects a risk factor management item (710).

[0402] The worker can select a major risk factor item (810) or a location-specific risk factor item (820) from among the risk factor management items (710). The worker can register a risk factor by selecting only one of the major risk factor item (810) and the location-specific risk factor item (820). Alternatively, the worker can register a risk factor in both the major risk factor item (810) and the location-specific risk factor item (820).

[0403] FIG. 8 is an example of a screen output on a terminal (200) when a major risk factor item (810) of FIG. 7 is selected. Referring to FIG. 8, a list (811) of major risk factors may be output on the screen of the terminal (200). Here, the outputted major risk factors may be risk factors that commonly occur regardless of location or risk factors that occur frequently statistically. At this time, among the outputted list (811) of major risk factors, the list with check boxes already checked is a risk factor that has already been discovered and registered in the safety management server (101).

[0404] The worker can select one or more risk factors corresponding to new risk factors from among the major risk factors displayed on the screen of the terminal (200). Additionally, if there is no risk factor corresponding to new risk factors among the list displayed on the screen of the terminal (200), the worker can directly record information about the new risk factor.

[0405] Figure 9 is an example of a screen displayed on a terminal (200) when a location-specific risk item (620) of Figure 7 is selected.

[0406] Among the risk items (620) by location in Figure 7, the worker can select the location of a new risk factor. For example, the location of the new risk factor may be a machine room. If the worker selects a machine room, the terminal (200) may display the screen of Figure 9.

[0407] Referring to Figure 9, a list of risk factors can be output for each location within the site. When a worker selects the location of a new risk factor, a list of risk factors for that location can be output on the terminal (200) screen. For example, if the worker selects a machine room, a list of risk factors for that machine room can be output on the terminal (200) screen.

[0408] The worker can select one or more risk factors corresponding to a new risk factor from the list displayed on the screen of the terminal (200). For example, a new risk factor can be added by checking the check box of the risk factor corresponding to the new risk factor in the risk factor list.

[0409] Additionally, if there is no risk factor corresponding to a new risk factor among the list displayed on the screen of the terminal (200), the worker can directly record information on the new risk factor by location.

[0410] Additionally, when a worker selects a location for a new hazard, the list of hazards at that location is not the only thing displayed on the terminal (200) screen. For example, when a worker selects a location for a new hazard, a list of hazards at the selected location may be displayed in the central area of ​​the terminal (200) screen. At this time, the worker can simultaneously check lists of hazards at other locations as well as the selected location by manipulating the terminal (200) screen with a finger or tool.

[0411] Additionally, the worker can add audiovisual information (830) on new risk factors for each site through the terminal (200).

[0412] Additionally, when the worker arrives at the site, at least some of the risk factors registered in the safety management server (101) may have been removed. Alternatively, at least some of the risk factors registered in the safety management server (101) may be removed through the worker's management tasks. In this case, the worker may delete information about the removed risk factors from the safety management server (101) through the application of the terminal (200).

[0413] The operator can delete information about previously registered risk factors that have been removed from the list of major risk factors (810) and location-specific risk factors (820). For example, in FIGS. 8 and 9 , check boxes already checked in the list of major risk factors (811) and location-specific risk factors (821) are previously registered risk factors. Removal of a risk factor can be accomplished by unchecking the checkbox of the risk factor.

[0414] Additionally, the worker can remove audiovisual information (830) of the removed hazard.

[0415] In the embodiment of the present invention, adding or deleting a risk factor to an application of a terminal (200) is performed by checking or unchecking the checkbox for the corresponding risk factor. However, the present invention is not limited to this. That is, various methods can be used to input new risk information into the terminal (200).

[0416] The worker can input new risk information including information that adds a risk factor to the application of the terminal (200) or deletes a previous risk factor and select transmit on the screen of FIG. 6.

[0417] When the terminal (200) receives a transmission signal, it can transmit new risk information of the corresponding site to the safety management server (101) (S65).

[0418] The safety management server (101) can update new risk information received from the terminal (200) to the information storage device (S66).

[0419] The risk information management device (120) can compare previous risk information stored in the risk information storage device (110) with new risk information received from the terminal (200) and apply changes to the previous risk information.

[0420] Through this process, when the safety management server (101) updates the risk information of the site, the safety management stage of the safety management system (50) can be terminated.

[0421] Additionally, the terminal (200) may not receive new risk information (S64).

[0422] If the terminal (200) does not receive new risk information, the safety management phase of the safety management system (50) may also be terminated.

[0423] Although the embodiment of the present invention describes that the step of receiving new risk information by the terminal (200) is performed after the step of outputting risk information of the corresponding site by the terminal (200), the present invention is not limited thereto. For example, if risk information of the corresponding site does not exist, the step of receiving new risk information by the terminal (200) may be performed before or after the step of requesting risk information from the safety management server (101). In addition, in this case, the risk information management device (120) may store the received new risk information as risk information of the corresponding elevator in the risk information storage device (110).

[0424] According to the safety management system (50) and safety management method according to the embodiment of the present invention, workers deployed to a site for regular maintenance or repair can identify risk factors at the site in advance. Therefore, workers can prepare for risks that may occur at the site. For example, workers can prepare equipment to remove risk factors at the site and remove them at the site. In addition, workers can prevent the occurrence of risks by identifying the location and status of risk factors that may occur at the site. Therefore, the safety management system (50) and safety management method according to the embodiment of the present invention enable workers to identify risk factors at the site in advance and efficiently establish site management plans. In addition, the safety management system (50) and safety management method according to the embodiment of the present invention can improve the safety of on-site work, and thus, work efficiency.

[0425] For example, while inspecting a machine room, a worker may discover a connector with damaged wire insulation, exposing the internal conductor. In this case, the worker can register the risk factor as "Machine Room → Risk of Electric Shock" through the application on his / her terminal (200). At this time, the worker can attach a photo showing the condition of the risk factor through the application on his / her terminal (200) and also register safety measures such as "Insulation required." Afterwards, the next worker on the elevator can recognize the risk factor in the machine room through his / her terminal (200), prepare safety equipment such as insulating gloves in advance, and safely perform the task.

[0426] As another example, the risk prediction device (301) can calculate the start date of operation of the elevator and the number of operations, and predict risk factors such as steps on the platform that may occur due to the aging of the elevator and rainwater inflow into the elevator that may occur due to heavy rain, and transmit the predicted risk factors to the safety management server (101). At this time, when a worker requests risk information about the elevator through a terminal (200), the safety management server (101) can transmit risk information about risk factors registered by a previous worker and risk factors by the risk prediction device (301) to the worker's terminal (200). The worker can perform the work safely by considering both the actual risk factors registered by a previous worker and the risk of accidents that may occur due to steps on the elevator and rainwater inside the elevator through the terminal (200).

[0427] [Configuration of the safety management system according to the 6th embodiment]

[0428] Figure 18 is a block diagram showing a safety management system according to the sixth embodiment of the present invention.

[0429] The safety management system (60) according to the sixth embodiment may include a terminal (200) and a safety management server (102). In addition, referring to FIG. 18, the safety management server (102) may include a risk information storage device (110), a risk information management device (120) that analyzes risk information, and a risk notification device (130) that sends a risk warning to a worker's terminal (200). The terminal (200), the risk information storage device (110), and the risk information management device (120) of the safety management system (60) of the present embodiment are identical to the terminal (200), the risk information storage device (110), and the risk information management device (120) of the safety management system (50) of the fifth embodiment of FIG. 15. Therefore, for a detailed description of the terminal (200), the risk information storage device (110), and the risk information management device (120) of the present embodiment, refer to the previous description. In addition, the description of the safety management system (60) of the present embodiment will be centered on the risk notification device (130) that is different from the safety management system of the fifth embodiment (50 of FIG. 15).

[0430] The risk notification device (130) of the safety management system (60) of this embodiment can transmit risk information to the worker's terminal (200) before the worker enters the site.

[0431] When a worker is deployed to a site for maintenance and repair, information about the worker deployed to the site can be entered and stored in the safety management server (102) by the manager. Here, the worker information may include information about not only the worker but also the worker's terminal (200). Furthermore, the manager may be the person who deploys the worker to the site requiring maintenance and repair. Alternatively, the manager may be a program or system that automatically deploys the worker to the site requiring maintenance and repair.

[0432] For example, a manager can transmit site information and information on workers deployed at the site to a risk information management device (120) of a safety management server (102). The risk information management device (120) can check whether risk information for the corresponding site is stored in the risk information storage device (110) based on the received site information. If risk information for the corresponding site exists in the risk information storage device (110), the risk information management device (120) can transmit a signal to a risk notification device (130).

[0433] When the risk notification device (130) receives a signal from the risk information management device (120), it can transmit a risk notification signal to the terminal (200) of a worker deployed at the site. More specifically, the risk notification device (130) can receive information about the site and the worker deployed at the site through the signal received from the risk information management device (120) and transmit a risk notification signal to the worker's terminal (200).

[0434] When the worker's terminal (200) receives a risk notification signal from the risk notification device (130) of the safety management server (102), it can output a risk alarm so that the worker can check the risk information. The risk alarm can be performed in various ways, such as an alarm, vibration, or light of the terminal (200).

[0435] As such, the safety management system (60) of the present embodiment can notify the worker of the presence of risk information (risk factors) at the relevant site in advance before the worker requests risk information. Therefore, the step in which the safety management system (60) notifies the worker of the risk information at the relevant site through the terminal (200) may be performed before the step in which the terminal (200) requests the risk information from the safety management server (102) among the steps of the safety management method of FIG. 17. Furthermore, the step in which the safety management system (60) notifies the worker of the risk information at the relevant site through the terminal (200) may be performed immediately after the step in which the risk information at the relevant site is generated or updated based on the risk prediction information of FIG. 16.

[0436] The safety management system (60) and safety management method according to this embodiment can notify workers in advance of the presence of hazards at a site, allowing them to search for information about the hazards at the site and prepare for them. Therefore, the safety management system (60) and safety management method according to this embodiment can ensure that workers are aware of the risks and perform their management tasks safely.

[0437] For example, a worker may be deployed to a machine room for regular inspection. The risk information management device (120) may retrieve information on risk factors predicted by the risk prediction device (301) stored in the risk information storage device (110) and risk factors registered by previous workers, and may search for risk factors for electric shock registered in the machine room.

[0438] The hazard notification device (130) transmits a hazard notification signal, which is a warning signal corresponding to the hazard, to the worker's terminal (200). Through the warning message output from the terminal (200), the worker can recognize electric shock hazards, such as damage to wire sheaths, before entering the work site, and can ensure safety during work by preparing insulating gloves or an insulating mat in advance.

[0439] In this way, the safety management system (60) according to the sixth embodiment of the present invention enables advance prevention by actively notifying workers of actual and potential risk factors before they enter the site.

[0440] As described above, the detailed description of the present invention has been made by way of embodiments with reference to the attached drawings. However, the above-described embodiments have only been described as preferred examples of the present invention, and therefore, the present invention should not be understood as being limited to the above-described embodiments, and the scope of the rights of the present invention should be understood by the claims described below and their equivalent concepts.
