Description

The present invention relates to a safety training system for workers.

At construction sites, there are tasks and environments where workers may be injured. For example, when performing unfamiliar tasks, workers may damage tools and materials, get in the way of themselves and other workers, or injure themselves by not moving properly or handling tools and materials properly. In addition, various tools, tools, materials, etc. are placed on the floor at the work site, so workers may come into contact with these tools and fall or be injured. Furthermore, at sites where floors and walls are unfinished, there may be holes or protrusions that do not exist on completed floors and walls, and workers may fall into holes or come into contact with protrusions and be injured. These injuries are often caused by the worker's level of proficiency in the work and the worker's attention, so there is a possibility that injuries and other accidents can be reduced by informing and helping workers understand the causes of injuries and other accidents and what they should be careful of. For this reason, in construction work, advance safety training (off-site training) is provided at the company or other organization before the actual construction work begins at the construction site, and on-site training is provided after construction work begins at the site.

Incidentally, as disclosed in Patent Document 1, a technique has been developed for constructing an educational facility where people can experience accidents and dangers that occur at construction sites and the like, and for experiencing accidents and dangers at the educational facility.
However, the technology of Patent Document 1 requires the construction of an educational facility, and therefore while it is possible to experience common accidents and dangers at a model site, it is not possible to experience accidents and dangers that occur at an actual site.

On the other hand, Patent Document 2 discloses a technology for training on the work site and detecting dangers based on 3D data. In the technology of Patent Document 2, when a specific location is selected in the 3D data, danger information and defect images are displayed, and at that time, problems regarding items to be confirmed at the site are filed.
However, while the technology of Patent Document 2 is capable of dealing with sites of various structures compared to the technology of Patent Document 1, the technology of Patent Document 2 does not provide information on dangers or problems at actual sites.

The technology in Patent Document 3 also develops a technology that automatically detects unsafe areas from structures that are the same as those at an actual construction site, based on a three-dimensional model formed by BIM.
However, the technology of Patent Document 3 only detects unsafe areas caused by structures, and cannot inform or educate workers about unsafe behavior caused by actual work. For example, it cannot inform or educate workers about dangerous acts during actual work or hazards caused by obstacles due to temporary placement of materials, tools, etc.

On the other hand, the technology of Patent Document 4 discloses a technology in which precautions related to work on site are included in the attribute information of the parts of the three-dimensional model registered in the BIM or stored separately in a precaution registration unit, and the work situation is judged based on the information acquired by the automatic patrol vehicle, and precautions according to the work situation are displayed on the three-dimensional model. It also discloses a technology to alert the worker by having the worker check the precautions displayed on the three-dimensional model before work. It also discloses a function to store newly discovered precautions in the precaution registration unit.
Therefore, by using the technology of Patent Document 4, it may be possible to inform workers to a certain extent of unsafe actions and dangers that may occur during on-site work regarding the parts they are working on.

JP 2019-219442 A JP 2020-190644 A JP 2020-95390 A JP 2021-156015 A

The technology of Patent Document 4 is desirable in that it allows workers to check precautions that correspond to an actual work site, but it merely displays the precautions on an image, and the workers cannot fully understand situations in which unsafe behavior may actually occur.
Even if the worker checks the precautions, it is not possible to determine whether or not the worker understands the precautions, and this is not sufficient training for the worker.

In view of the above circumstances, the present invention aims to provide a safety education system for workers that can help workers understand unsafe behaviors that correspond to actual work sites.

The worker safety training system of the fourth invention is characterized in that, in the first invention, the inputters are workers who perform work at the work site of the work site image and a work manager who manages the work in the work site image, and the confirmation image display function of the control unit has a function of displaying both the worker warning information and the work manager warning information on the image display unit simultaneously with the confirmation image to which they are associated when worker warning information, which is warning information input by the worker, and work manager warning information, which is warning information input by the work manager, are stored in association with the same confirmation image.
The worker safety education system of the fifth invention is the first invention, comprising an image display device having a display unit that is worn by a worker and displays an image viewed by the worker, and an experience facility simulating a work site where the worker wearing the image display device experiences work, wherein the image display device has an imaging function that images an area visible to the worker, and the control unit has a detector that detects the movement of the worker wearing the image display device, and a training image control function that displays an MR image on the display unit of the image display device based on a signal from the detector, an image of the experience facility captured by the imaging function, and a BIM model which is an image of the work site that is the basis of the experience facility formed by a BIM system, and wherein the confirmation image display function has a function of displaying the MR image on the image display unit as the confirmation image together with the warning information.
The worker safety training system of the sixth invention is characterized in that, in the fifth invention, the experience equipment is equipped with work-related objects which are objects related to the work performed by workers at the work site which is the basis of the experience equipment, and objects among the work-related objects which are fixed to the experience equipment are provided with alignment marks which are used to align the BIM model with the captured image.
The seventh invention is a worker safety training system in accordance with the first invention, which has an image display device having a display unit that is worn by a worker and displays an image that the worker can see, and the control unit has a training image control function that causes a VR image to be displayed on the display unit of the image display device based on a BIM model of a work site where the worker will have work experience, which is formed by a BIM system, and the confirmation image display function has a function that causes the VR image to be displayed on the image display unit as the confirmation image together with the warning information.

FIG.

The worker safety education system of this embodiment is a system used to provide safety education to workers who perform work at work sites and the like, and is used to deepen workers' awareness and understanding of unsafe behavior.

The timing and location of safety education using the worker safety education system of this embodiment is not particularly limited. For example, it can be used for education to help workers understand the work to be done at the work site before starting work at the work site (so-called off-site education), or for education to help workers understand the work to be done that day after work has started at the actual work site (so-called on-site education). In addition to off-site education and on-site education, it can also be used for safety education at regular in-house study sessions and seminars and training sessions held by construction industry associations, etc.

The work for which safety education is provided using the worker safety education system of this embodiment is not particularly limited, and it can be adopted for safety education of various work performed at work sites. For example, the worker safety education system of this embodiment can be used for safety education in various work such as installing plasterboard on the walls and ceilings of a work site (plasterboard installation work), high-altitude work such as ceiling construction, and material transportation and delivery work such as iron pipes and steel frames.

In the following explanation, we will use the worker safety training system of this embodiment to provide safety training for plasterboard installation work as an example.

<Worker Safety Education System 1 of the Present Embodiment>
1, the worker safety education system 1 of this embodiment includes an image display unit 2 that displays an image to be checked by a worker or a work manager, an input unit 3 that inputs caution information and the like described below, an image display device 5 worn by a worker or the like experiencing the safety education, and a control unit 10 that controls the operation of the image display unit 2, the input unit 3, and the image display device 5. The worker safety education system 1 of this embodiment also includes an experience facility 30 that is a facility where a worker or the like experiences the safety education.

<Control Unit 10>
1, the control unit 10 is connected by wire or wirelessly to the image display unit 2, the input unit 3, and the image display device 5 so as to be able to transmit and receive signals therebetween. The control unit 10 has a training image control function 11 that controls images (such as a confirmation image or caution information) to be displayed on the image display unit 2 and images to be displayed on the display unit 5a of the image display device 5 during the experience work. For example, the control unit 10 has the training image control function 11 that controls which images are to be displayed on the image display unit 2 and the display unit 5a of the image display device 5 and at what timing.

The training image control function 11 of the control unit 10 has a function of generating MR (Mixed Reality) images and VR (Virtual Reality) images as images to be displayed on the display unit 5a. Specifically, the control unit 10 has a function of generating VR images and MR images based on information of a 3D model (hereinafter referred to as a BIM model, see Figures 2 (A) and (B)) created by software (referred to as a BIM system in this specification) that realizes Building Information Modeling (BIM). For example, in the case of a VR image, the BIM model of the work site can be used as a VR image as it is, and the BIM model can be modified to include information (shape information) on the three-dimensional shape and structure of the target structure, such as holes and protrusions, and information (attribute information) on letters and numbers of members or parts. In addition, in the case of an MR image, an MR image can be created by superimposing the BIM model and an image (photographed image) captured by the capture function of the image display device 5 described below, or an MR image can be created by superimposing the BIM model and/or the photographed image with modifications such as shape information and attribute information.

If the images (3D models) from which the training image control function 11 of the control unit 10 generates VR images and MR images are images created by a BIM system, the VR images and MR images viewed by the worker can reproduce a situation that is nearly equivalent to the actual work site where the work experience is carried out. However, the images (3D models) from which the VR images and MR images are generated do not necessarily have to be images created by a BIM system. It is sufficient that the images can reproduce a situation close to the actual work site when the training image control function 11 of the control unit 10 generates the VR images and MR images.

<Memory function 15>
In addition, the control unit 10 has a memory function 15 that associates the images displayed on the image display unit 2 and the images displayed on the display unit 5a of the image display device 5 with information input from the input unit 3 (warning information, information on estimated danger locations, etc.) and stores them in the memory unit 20.

For example, when an experiential task such as that described below is performed, the memory function 15 has a function of storing in the memory unit 20, in association with the worker who performed the work experience, the date on which the work experience was performed (experience date), the image displayed on the image display unit 2 during the work experience, and the image displayed on the display unit 5a of the image display device 5.

The memory function 15 also has a function of associating the experience image with the information input from the input unit 3 and storing them in the memory unit 20 when information is input from the input unit 3 while the experience image display function 13 of the display function 12 described below is displaying an image (experience image) of the worker performing the work experience on the image display unit 2.

The storage function 15 also has a function of providing stored information based on commands from other functions or devices. For example, when a command is supplied to the storage function 15 from the experience image display function 13 or confirmation image display function 14 of the display function 12 to specify an experience image and read out stored information, the storage function 15 has a function of providing the specified experience image and information stored in association with that experience image to the experience image display function 13 or confirmation image display function 14 of the display function 12. Specifically, when the experience image display function 13 or confirmation image display function 14 of the display function 12 provides information such as the worker's name and ID and the date the experience work was performed, the storage function 15 has a function of providing the experience image and information of the corresponding experience work to the experience image display function 13 or confirmation image display function 14 of the display function 12.

<Experience Facility 30>
The experience facility 30 is a facility having a structure simulating a work site where a worker (hereinafter, sometimes simply referred to as a worker) receiving safety training will be working or a work site where the worker is currently working. The experience facility 30 is a facility where a worker experiences work, and is a facility in which work-related objects, which are objects related to the work performed by the worker at the work site, are arranged. For example, in the case of performing plasterboard installation work as shown in FIG. 3, a model of the base material of the wall on which the plasterboard is to be installed (see FIG. 2(C)), the plasterboard to be installed on the base material (see FIG. 2(D)), and tools such as an electric drill used to install the plasterboard on the base material are arranged as work-related objects in the experience facility 30.

The experience facility 30 is also provided with a number of sensors 31 that detect the position of the worker. These sensors 31 have the function of detecting the worker. When signals from these sensors are transmitted to the training image control function 11 of the control unit 10, the training image control function 11 can analyze the signals from the sensors to grasp the current position of the worker within the experience facility 30, whether the worker is moving, the direction of the worker's movement, etc. (hereinafter, these may be collectively referred to as the "state of the worker"). Therefore, the training image control function 11 can create VR images and MR images that match the state of the worker. Such sensors may be infrared sensors, ultrasonic sensors, camera sensors, etc., but are not particularly limited as long as they can achieve the above purpose.

In the case of the plasterboard installation work described above, the model of the base material is installed in a fixed state in the experience equipment 30 (so that it does not move even when the plasterboard installation work is performed). On the other hand, the plasterboard and tools are arranged in a state where the worker can pick them up and carry them, and fix the plasterboard to the model of the base material.

In addition, when the plasterboard installation work involves installing plasterboard at a high position or on the ceiling, the treadmill, mobile scaffolding, and framework scaffolding on which the worker stands while working are either fixed to the experience facility 30 (so that they do not move even when the plasterboard installation work is being performed) or set up so that they can be moved (see Figures 3 (A) to (C)).

In addition, the work-related items that are fixedly installed in the experience facility 30 may be suitable for the work that the worker will experience, and the work-related items that are movably placed in the experience facility 30 may be tools, etc., that are suitable for the work that the worker will experience.

<Image display device 5>
The image display device 5 is worn by a worker when experiencing work in the experience facility 30. This image display device 5 has a display unit 5a that displays an image that allows the wearing worker to visually recognize the image. More specifically, the image display device 5 has the display unit 5a that is placed in front of the worker's eyes when the worker wears the image display device 5, and allows the worker to visually recognize the image (MR image or VR image) displayed on the display unit 5a. This image display device 5 has a function of detecting the face direction of the wearing worker, a function of detecting the line of sight, etc.

When the MR image is displayed on the display unit 5a, the image display device 5 has a photographing function for photographing images (e.g., images of the experience facility 30) required for the control unit 10 to form an MR image. More specifically, the image display device 5 has a photographing function for photographing an area visible to the worker when the worker is not wearing the image display device 5. For example, a general head-mounted display having a stereo camera that photographs the area in front of the image display device 5 can be used as the image display device 5.

The image display device 5 is not particularly limited as long as it can be worn by the worker and has the above-mentioned functions, but a head-mounted display such as the one described above can be used.

The image display device 5 may have a function to detect the movement, changes in posture, and hand movements of the worker, as well as a function to detect the direction of the worker's face and the line of sight, etc. In this case, it may not be necessary to provide a sensor 31 in the experience equipment 30 described above, and even if sensors 31 are provided, the number of sensors may be reduced. When detecting the movement, changes in posture, and hand movements of the worker, the image display device 5 may be provided with a sensor to detect these movements and detect the worker's movement, etc., or the control unit 10 may analyze images of hands, etc. in the images captured by the image display device 5 and detect these movements. Of course, the movement of the worker, etc. may be detected using both a sensor and image analysis.

The image display device 5 does not necessarily have to have a function for detecting the face direction of the worker wearing the image display device 5 or a function for detecting the line of sight of the worker, and may be capable of allowing the worker to visually recognize the image (MR image or VR image described later) displayed on the display unit 5a. If the image display device 5 does not have a function for detecting the face direction of the worker wearing the image display device 5, a sensor for detecting the face direction of the worker may be attached to the image display device 5 or the worker's head to detect the face direction of the worker. Although the function for detecting the line of sight of the worker is not necessarily provided, it is preferable that the image displayed on the display unit 5a be a more appropriate image, and the state of the worker, such as whether the worker is visually checking for safety, can be grasped more accurately, which can be useful for the safety manager to provide appropriate guidance.

<Image display unit 2>
The image display unit 2 is a general display device and can display an image supplied from the control unit 10. The image display unit 2 may be any device capable of displaying an image supplied from the control unit 10. For example, when the control unit 10 has a display like a notebook computer, the display of the control unit 10 can be used as the image display unit 2. Even when the control unit 10 has a display, a display device (separate display device) provided separately from the display of the control unit 10 may be used as the image display unit 2. A plurality of image display units 2 may be provided. In this case, both the display of the control unit 10 and the separate display device may be used as the image display unit 2, or a plurality of separate display devices may be provided and only the separate display devices may be used as the image display unit 2.

<Input section 3>
The input unit 3 has a function of inputting various information and a function of supplying the input information to the control unit 10. For example, the input unit 3 has a function of inputting information of a worker who is undergoing a work experience through the worker safety education system 1 of this embodiment and information of a person supervising the work experience of the worker (such as a work manager who monitors the status of the work experience) and supplies the input information to the control unit 10. The input unit 3 also has a function of inputting caution information and information of estimated dangerous places, which will be described later. As described above, the information input from the input unit 3 is transmitted to the control unit 10, and the information is stored in the storage unit 20 by the storage function of the control unit 10 in association with the image displayed on the image display unit 2 and the image displayed on the display unit 5a of the image display device 5.

The input unit 3 may be, for example, a keyboard, a mouse, a touch panel, etc., but is not particularly limited as long as it allows a worker or work manager to input the specified information. If voice input is to be performed as described below, the input unit 3 may be a device capable of voice input (for example, a microphone or a device with a built-in microphone) in addition to a keyboard, etc.

<Work experience using the safety education system 1 of this embodiment>
Since the worker safety training system 1 of this embodiment has the above-mentioned configuration, it is possible to allow the worker to carry out work experience as follows (see FIG. 4).
In the following, a case where an MR image is displayed on the display unit 5a of the image display device 5 will be described.

First, information about the worker who will be performing the work experience and information about the work manager of the worker who will be performing the work experience are input from the input unit 3. After input of the required information is completed, the worker who will be performing the work experience is made to wear the image display device 5.

Then, the display position of the BIM model in the MR image is adjusted so that the image of the experience facility 30 captured by the imaging function of the image display device 5 matches the BIM model in the MR image. For example, if the experience facility 30 is a facility for experiencing the work of laying plasterboard on the base material of a wall, the display position of the BIM model in the MR image is adjusted so that the model of the base material of the experience facility 30 in the captured image matches the base material of the BIM model.

The display position may be adjusted automatically by the control unit 10 when the photographing function of the image display device 5 photographs a model of the base material of the experience facility 30, or it may be adjusted manually while checking the MR image.

In addition, if alignment marks are provided on the model of the base material of the experience facility 30 for alignment, the control unit 10 can easily and automatically adjust the position. For example, if a QR code (registered trademark) is used as the alignment mark and information such as the coordinate values in the three-dimensional space represented in the BIM model (the coordinate values in the three-dimensional space of the position where the QR code (registered trademark) is provided) is included in the QR code (registered trademark), the control unit 10 can adjust the position simply by photographing the QR code (registered trademark) using the photographing function of the image display device 5.

When the control unit 10 finishes adjusting the position, a command to start work is input from the input unit 3, and the MR image displayed on the display unit 5a of the image display device 5 also starts to be stored in the storage unit 20. The worker then performs the plasterboard installation work based on the MR image displayed on the display unit 5a of the image display device 5 (see Figures 3(A) to (C)). At this time, both or either one of the MR image displayed on the display unit 5a of the image display device 5 and the BIM model of the work site used to form the MR image (i.e., the BIM model of the work site including areas other than those visible by the worker) are displayed on the image display unit 2. This allows the work manager, etc. to check the viewpoint of the worker experiencing the work and the overall situation of the work site.

When the series of tasks is completed, a command to end the tasks is input from the input unit 3, and the experience task ends. Then, the control unit 10 stops displaying the MR images on the display unit 5a of the image display device 5 and stops storing the MR images in the storage unit 20.

As described above, by using the worker safety education system 1 of this embodiment, actual plasterboard installation work can be performed while visually viewing MR images that recreate an actual work site, allowing the worker to have a work experience similar to that of working at an actual work site. This can help the worker recognize the things they need to be careful of at an actual work site and raise the worker's awareness of unsafe behavior.

For example, in an actual work site, there may be a through hole in the floor, and the worker must move around while avoiding the through hole. When experiencing work at such a work site, the MR image reproduces a state that is almost identical to the actual work site, so even if the experience equipment 30 has a floor without a through hole, the through hole is displayed in the MR image (see h in FIG. 2B). Therefore, the worker can experience moving around the work site while being aware of the presence of the through hole. Moreover, since the worker can be made aware of the presence of the through hole in the actual work site, it is more effective in preventing accidents such as falling without noticing the through hole when working at the actual work site. In addition, if a warning sound or the like is issued when the worker's foot is placed at the position of the through hole, the worker can be made more aware of the presence of the through hole, and the effect of preventing accidents can be further increased.

<When a VR image is displayed on the display unit 5a of the image display device 5>
In the above example, a case where an MR image is displayed on the display unit 5a of the image display device 5 has been described, but when a VR image (see FIGS. 3D to 3F) is displayed on the display unit 5a of the image display device 5, the experience facility 30 as described above does not need to be provided. On the other hand, in this case, the worker needs to grasp and operate the plasterboard, tools, etc. displayed as the VR image with the worker's hands displayed in the VR image. In this case, the positions of the worker's hands and the plasterboard, tools, etc. in the VR image need to be aligned and displayed in the VR image, so that a sensor (e.g., a glove-shaped sensor, etc.) that detects the position and movement of the worker's hands needs to be worn in order to detect the worker's hands.

<Safety confirmation training by the worker safety training system 1 of this embodiment>
As described above, by carrying out a work experience using the safety education system 1 for workers of this embodiment, it is possible to make the worker aware of the situation at the work site, dangerous actions, etc. In order to further strengthen the worker's awareness, that is, to enhance the effectiveness of safety education, it is desirable for the worker to check the situation of his/her own work experience after carrying out the work experience and to consider by himself/herself or together with the work manager whether or not there was any unsafe behavior in the work.

Therefore, the worker safety education system 1 of this embodiment has a function to allow the worker who has completed the work experience to check the situation of the experience work and to consider whether or not there was any unsafe behavior.

<Display function 12>
As shown in FIG. 1, the control unit 10 of the worker safety training system 1 of this embodiment has a display function 12 that causes the image display unit 2 to display a confirmation image or the like for confirming the work status of a worker who has completed the work experience.

The display function 12 has an experience image display function 13 that causes the image display unit 2 to display VR images and MR images (hereinafter simply referred to as experience images) of the worker performing the work experience, which are stored in the memory unit 20, and a confirmation image display function 14 that causes the image display unit 2 to display the experience image and warning information, etc. input from the input unit 3 when the experience image is displayed by the experience image display function 13.

<Experience image display function 13>
The experience image display function 13 has a display function 13a that selects an experience image to be displayed on the image display unit 2 based on information input from the input unit 3 and displays the experience image on the image display unit 2, and an information storage function 13b that associates information input from the input unit 3 with the displayed experience image while the experience image is being displayed and stores the associated information in the storage unit 20.

The display function 13a has a function of sending an image request command including selection information to the storage function 15 based on the experience work information (such as the worker's name and the experience work date, hereinafter sometimes simply referred to as selection information) input from the input unit 3. Then, when the experience image or information stored in association with the experience image (hereinafter both may be simply referred to as experience image information) is provided from the storage function 15 based on the image request command, the display function 13a has a function of continuously displaying multiple images (frames) included in the experience image included in the provided experience image information on the image display unit 2. The experience images are MR images or VR images that were displayed on the display unit 5a of the image display device 5 while the worker was performing the experience work (see Figures 3 (D) to (F)), and the display function 13a causes the selected experience images to be continuously displayed on the image display unit 2.

Note that in the following, successive display of multiple images (frames) included in the experience image may simply be referred to as "successively displaying experience images."

When warning information is input from the input unit 3 while the experience image is being displayed by the display function 13a, the information storage function 13b has a function of adding the input warning information to the experience image information and supplying it to the storage function 15 as training result information. More specifically, the information storage function 13b has a function of associating the image (frame) at the timing when the warning information was input from the input unit 3, the information of the person who input the warning information, and the input warning information in the experience image, adding them to the experience image information, and supplying them to the storage function 15 as training result information.

The warning information is information that specifies the unsafe behavior recognized when the worker judges that an unsafe behavior has occurred or that an unsafe behavior may occur when the worker checks the experience image. There is no particular limit to the method of inputting the warning information or the format in which the warning information is input. The warning information may be freely written in text format, or the inputter may select warning information corresponding to the unsafe behavior recognized by the inputter from predetermined words, symbols, marks, etc. (hereinafter referred to as tags). For example, the input unit 3 may be provided with an unsafe behavior table having tags that display multiple unsafe behaviors expected in the experience image (see FIG. 7(A)), and an appropriate tag may be selected from this unsafe behavior table and input as the warning information. In the case of FIG. 7(A), a drop tag, a toppling tag, and a collision tag are prepared as tags that display unsafe behaviors, so if the inputter selects and saves a tag that corresponds to the unsafe behavior recognized by the inputter from these tags, the tag information is associated with the image (frame) in which the tag is saved and stored in the training result information.

The information storage function 13b also has a function that allows the worker to input information on estimated dangerous locations where unsafe behavior may occur when inputting caution information. Specifically, after inputting caution information by the input unit 3 or before inputting caution information, the information storage function 13b has a function of selecting the estimated dangerous location or its vicinity in the experience image with a mouse or the like to specify the estimated dangerous location. The information storage function 13b then has a function of adding the input information on the estimated dangerous location to the training result information and supplying it to the storage function 15. If the above-mentioned tag is prepared, the information storage function 13b may have a function of inputting information on the estimated dangerous location by placing an image of the selected tag at the estimated dangerous location.

In addition, the information storage function 13b does not necessarily need to supply the information on the estimated dangerous place to the storage function 15 in a state in which the information is added to the training result information. In this case, the information storage function 13b may supply the information on the estimated dangerous place to the storage function 15 in association with information that associates the information on the estimated dangerous place with the corresponding caution information in the training result information (for example, information on the corresponding image (frame) of the experience image, etc.).

In addition, the information storage function 13b does not necessarily have to be configured to input information on estimated dangerous locations. However, if information on estimated dangerous locations is also configured to be input, it will be possible for the person who inputted the warning information to properly understand actions that the person who inputted the warning information recognizes as unsafe actions, and it will also be easier for the work manager, etc. to evaluate whether the person who inputted the warning information has properly understood unsafe actions.

<Confirmation image display function 14>
The confirmation image display function 14 has a function of selecting training result information to be displayed on the image display unit 2 based on information input from the input unit 3, and displaying the experience image and warning information included in the training result information on the image display unit 2. Specifically, the confirmation image display function 14 has a function of successively displaying images (frames) of the experience image included in the training result information, and displaying the experience image and the warning information simultaneously on the image display unit 2 for an experience image for which warning information has been input.

In addition, when information on an estimated dangerous location is input in the training result information, it has a function of displaying warning information in the experience image at the location specified as the estimated dangerous location or in its vicinity, that is, displaying the experience image and the warning information superimposed. For example, when tag information is included in the training result information as warning information, it has a function of displaying a tag in the image where an unsafe behavior has occurred (or is estimated) near the location where the unsafe behavior has occurred (or is likely to occur) (estimated dangerous location), as shown in FIG. 7(B).

<Example of safety confirmation training by the worker safety training system 1 of this embodiment>
A method of safety confirmation training using the worker safety training system 1 of this embodiment will be described.

First, we will explain how to input caution information during safety training (see Figure 5).

The experience image display function 13 of the display function 12 of the control unit 10 is activated to select the work experience for which safety confirmation training is to be carried out. Specifically, the selection information, such as the name of the worker who carried out the experience work and the date on which the experience work was carried out, is input from the input unit 13. Note that if multiple workers carry out the experience work multiple times and an ID is set for each experience work, the ID may be input from the input unit 13.

When the selection information is input, the experience image display function 13 of the display function 12 transmits an image request command to the memory function 15 based on the selection information. The memory function 15 then reads out the experience image information corresponding to the selection information from the memory unit 20 and supplies the experience image information to the experience image display function 13.

When the experience image information is supplied, the display function 13a of the experience image display function 13 causes the experience images to be continuously displayed on the image display unit 2. The timing to start displaying the experience images may be determined by an inputter such as an operator who checks the experience images by operating the input unit 13, or the display of the experience images may be automatically started after a certain period of time has elapsed since the selection information was input.

When a worker checking the experience image displayed on the image display unit 2 determines that an unsafe behavior has occurred or that there is a possibility that an unsafe behavior may occur, the worker inputs warning information (worker warning information) from the input unit 3. At this time, the display of the experience image is temporarily stopped at the state of an image where it is determined that an unsafe behavior has occurred or that there is a possibility that an unsafe behavior may occur, and the warning information is input. For example, if an unsafe behavior table is provided, a tag corresponding to the unsafe behavior recognized by the worker is selected from the unsafe behavior table, and the tag is placed at an estimated hazard location where there is a possibility that an unsafe behavior may occur. The information storage function 13b then associates the experience image displayed in the temporarily stopped state with the warning information and stores them.

When the display of the experience image is completed, the information storage function 13b supplies the training result information in which the warning information has been added to the experience image information to the storage function 15. The storage function 15 then stores the training result information supplied from the information storage function 13b in the storage unit 20 in association with the experience image information that is the source of the training result information.

The work manager also checks the experience images of the same work experience in the same way. The training result information for the same experience image then includes the worker manager caution information entered by the work manager.

Next, we will explain how workers will experience the tasks during safety confirmation training (see Figure 6).

When training result information that also includes worker attention information is formed, the confirmation image display function 14 of the display function 12 is activated to select the training result information to be confirmed. The method of selecting training result information can be the same as that of the experience image display function 13.

When the selection information is input, the confirmation image display function 14 of the display function 12 sends an image request command to the memory function 15 based on the selection information. The memory function 15 then reads out the training result information corresponding to the selection information from the memory unit 20 and supplies the training result information to the confirmation image display function 14.

When the training result information is supplied, the confirmation image display function 14 causes the experience images contained in the training result information to be continuously displayed on the image display unit 2. Note that, similar to the experience image display function 13, the timing at which to start displaying the experience images may be determined by an inputter such as an operator who checks the experience images by operating the input unit 13, or the display of the experience images may be automatically started after a certain period of time has elapsed since the selection information was input.

The confirmation image display function 14 continuously displays experience images, but when it comes to an image for which either worker caution information or worker manager caution information has been input, it pauses on that experience image and displays the experience image and the caution information simultaneously on the image display unit 2. For example, when a tag selected from the unsafe action table is placed at an estimated hazard location and caution information is input, the selected tag is displayed superimposed on the location where the tag was placed in the experience image (see FIG. 7(B)). Note that if the tag placed by the worker and the tag placed by the worker manager are placed at the same position in the same experience image, or if placing the tag would hide important information in the experience image, the tag is placed near the estimated hazard location (see FIG. 7(C)).

Here, if the tag placed by the worker and the tag placed by the worker manager are placed in the same position in the same experience image (see FIG. 7(C)), it can be evaluated that the worker has properly recognized the unsafe behavior. In other words, when the worker who has performed the work experience checks this experience image, he or she can confirm that his or her recognition is correct, and when the work manager checks this image, it can be evaluated that the worker has properly recognized the unsafe behavior.

On the other hand, if a worker does not place a tag on the experience image where the worker manager has placed the tag, or if the worker places a tag but the type of tag is different from the tag placed by the worker manager, or if the same tag is placed in the wrong position, it can be evaluated that the worker does not recognize the unsafe behavior. In other words, when a worker who has performed the work experience checks this experience image, he or she can understand that he or she does not recognize the unsafe behavior, and when a work manager checks this image, it can be evaluated that the worker does not recognize the unsafe behavior. In addition, since the worker can check the experience image where the worker manager has placed the tag, the type of tag, the position of the tag, etc., he or she can deepen his or her awareness of unsafe behavior. When the work manager checks this image, it is possible to understand the worker's awareness of unsafe behavior and to discover unsafe behavior that the worker manager himself or herself has not recognized.

As described above, by implementing safety confirmation education using the worker safety education system 1 of this embodiment, workers can deepen their understanding of unsafe behavior, and workers and worker managers can appropriately evaluate the unsafe behavior of workers. In particular, workers can use images of the work site they are about to perform to check experience images of the work they performed themselves and understand unsafe behavior, which can suppress the occurrence of unsafe behavior at the work site, i.e., improve the effectiveness of safety education for workers.

In particular, if the worker who performed the trial work and the manager who entered the worker manager warning information for the trial work review the trial images together, the worker can ask questions about the difference between the worker warning information and the worker manager warning information, and the worker manager can explain it, which can deepen the worker's awareness of unsafe behavior.

<About confirmation image display function 14>
In the above example, the confirmation image display function 14 has been described as pausing the display of an experience image in which caution information has been input, but the experience image may be continuously displayed even in cases where caution information has been input. However, it is preferable to display the experience image in which an unsafe behavior has occurred (or is estimated) as a still image, since this allows the state of the unsafe behavior and the caution information to be clearly recognized. Of course, when the experience image is continuously displayed even in cases where caution information has been input, the image can be made to be paused when a pause command is input from the input unit 3.

When the confirmation image display function 14 displays the experience image on the image display unit 2, the confirmation image display function 14 may always display the worker caution information and the worker manager caution information together with the experience image (see FIG. 7(C)). In addition, when a display command is received from the input unit 13, if caution information is input to the experience image to which the command is input, the caution information may be displayed together with the experience image, and if caution information is not input, nothing may be displayed (the experience image may remain displayed), or a mark indicating an error may be displayed. In this way, when the experience image is confirmed, the effect of the worker considering the occurrence of an unsafe behavior each time and increasing awareness of the unsafe behavior can be obtained. For example, when the worker confirms the experience image displayed by the confirmation image display function 14 and recognizes the existence of an unsafe behavior, a display command may be input, and if the caution information is displayed, it can be confirmed that the awareness of the unsafe behavior is stable. In addition, if the caution information is not displayed, it can be confirmed that the awareness of the unsafe behavior is not stable. Furthermore, if the worker caution information is not displayed but the worker manager caution information is displayed, it can be confirmed that the awareness of the unsafe behavior of the worker has improved.

In addition, if estimated danger location information has been input, the warning information may be displayed superimposed on the experience image at or near the estimated danger location, or may be displayed in a separate window, etc. In addition, if estimated danger location information has not been input, the warning information may be displayed superimposed on the experience image at a predetermined desired position, or may be displayed in a separate window, etc.

<Add information function>
The confirmation image display function 14 may have an information addition function for adding information to the already inputted caution information. If such a function is provided, awareness of unsafe behavior can be further improved. For example, if the worker's awareness can be confirmed by adding to the caution information what the worker notices when checking the experience image and storing it. Also, if the worker and the work manager input the work manager's comments when checking the experience image together, the worker can reconfirm the work manager's comments when checking the experience image alone. In this way, even if the work manager is not present, the same educational effect can be obtained as when the work manager and the worker check the experience image together. For example, if the work manager's comments include why the behavior is unsafe (the reason why it is considered to be unsafe) and what should or should have been done to avoid the unsafe behavior (method of avoiding the unsafe behavior), the worker's understanding of the unsafe behavior can be deepened. In addition, if additional information such as worker comments on why they acted in that way (causes of unsafe behavior) and answers to questions about what they could have or should have done to avoid the unsafe behavior (methods to avoid unsafe behavior) is included as additional information, workers' awareness of unsafe behavior can be improved.

In this case, the method of adding information to the warning information may be to add information as text using a keyboard or the like, or to add information as audio information. For example, the input unit 13 is provided with an audio input function, and the confirmation image display function 14 is provided with a selection function 14a for selecting warning information. When warning information is selected by the selection function 14a, an audio storage function 14b is provided for storing the audio input by the audio input function of the input unit 13 in association with the selected warning information and information about the selector who selected the warning information (i.e., the inputter). Then, conversations about the warning information between the work manager and the worker who are checking the experience video can be stored, so that by checking the conversations later, the worker can reconfirm the points made by the work manager when checking the experience image alone. Then, even if the work manager is not present, it is possible to obtain the same educational effect as when the experience image is checked together with the work manager. The audio storage function 14b may store the audio information as it is as additional information, or may convert the audio information into text information and store it.

<Evaluation function 16>
The control unit 10 may have an evaluation function 16 that evaluates the worker based on the warning information included in the experience image. The experience video and the warning information are stored in the storage unit 20 in association with information on the worker who performed the experience work in the experience video and the worker who inputted the warning information. Therefore, by using the warning information and the information on the worker from the information on the experience video stored in the storage unit 20, it is possible to objectively judge each worker's awareness of unsafe behavior. If such a judgment is obtained, it is possible to provide safety education suitable for each worker in order to solve problems specific to each worker.

For example, if a worker is able to adequately predict and avoid falls and trips, but is unable to adequately predict and avoid collisions, it can be determined that the worker has low attention to other workers working at the same time (see Figure 8 (A)).
In addition, if a worker is able to adequately predict and avoid a fall but is unable to adequately predict and avoid a topple, it can be determined that the worker is sufficiently attentive to large obstacles, but not to small obstacles (see Figure 8 (A)).
Furthermore, even in the case of plasterboard installation work, if a worker is able to adequately foresee and avoid unsafe behavior in wall installation work but is unable to adequately foresee and avoid unsafe behavior in ceiling installation work, it can be determined that the worker is not good at ceiling installation work (see Figure 8 (B)).

There are no particular limitations on the method for presenting such evaluations, but for example, if they are displayed as a table such as a graph as shown in Figure 8, workers and work managers can easily understand the characteristics of the workers and easily compare them with other workers.

In addition, if the warning information includes audio information as described above, it is possible to analyze the words contained in the audio information and evaluate the characteristics of each worker.

<Another Example of Safety Confirmation Training by the Worker Safety Training System 1 of the Present Embodiment>
In the above example, the case where the safety confirmation training was conducted based on images obtained when the worker who performs the safety confirmation training experienced work was described, but the images (corresponding to the confirmation images in the claims) used in the safety confirmation training by the worker safety training system 1 of this embodiment are not necessarily limited to images obtained during the work experience. For example, the above-mentioned safety confirmation training may be conducted using only a BIM model prepared in advance by a BIM system or the like. In this case, the worker safety training system 1 may not have the image display device 5 or the experience facility 30, and the control unit 10 may not have the training image control function 11 or the function of storing each piece of information obtained in the experience work in the memory function 15. In other words, the system configured with the control unit 10 having the display function 12 using the BIM model prepared in advance, the experience image display function 13, and the memory function 15 not having the function of storing each piece of information obtained in the experience work, the image display unit 2, and the input unit 3 may be used as the worker safety training system 1 of this embodiment.

The worker safety training system of the present invention is suitable for use as a system for pre-work training at a work site or for on-site training at a work site.
