DETAILED DESCRIPTION OF THE INVENTION

[0013] <Outline of the embodiment> Before describing the embodiments in detail, an overview of the embodiments will be described. Fig. 1 is a block diagram showing an example of the configuration of an information processing device 1 according to the outline of the embodiments. As shown in Fig. 1, the information processing device 1 includes a notification transmission unit 2 and a display control unit 3.

[0014] The notification sending unit 2 sends an emergency notification that notifies a worker of an emergency situation when a predetermined condition is met. The information processing device 1 is, for example, a device carried by the worker, and the notification sending unit 2 sends a notification (emergency notification) that notifies the worker carrying the information processing device 1 of an emergency situation when a predetermined condition is met. The notification sending unit 2 sends the emergency notification to, for example, a terminal operated by a leader who commands the workers, but may also send the emergency notification to another information processing device carried by another worker (for example, an information processing device having a similar configuration to the information processing device 1). The notification sending unit 2 may also send the emergency notification to any device, such as a server.

[0015] The display control unit 3 controls the display of information related to emergency notifications on a head-mounted display. Specifically, the display control unit 3 controls the display to be performed on a head-mounted display worn by a worker carrying the information processing device 1. This head-mounted display is provided, for example, on protective gear worn on the worker's head. Here, the protective gear worn on the head is, for example, a facepiece such as a protective mask, but is not limited to this and may also be a helmet, protective glasses, or the like.

[0016] The information related to the emergency notification that the display control unit 3 displays on the head-mounted display may be information related to a notification informing the worker carrying the information processing device 1 of the occurrence of an emergency, or may be information related to a notification informing another worker carrying another information processing device of the occurrence of an emergency. In other words, the information displayed on the head-mounted display may be information related to an emergency notification transmitted by the notification transmission unit 2 of the information processing device 1, or may be information related to an emergency notification transmitted from another information processing device.

[0017] According to the information processing device 1, information related to the emergency notification transmitted by the information processing device 1 or another information processing device (for example, an information processing device having a similar configuration to the information processing device 1) is displayed on a head-mounted display. This allows the worker to visually recognize the information related to the emergency notification. However, when information is transmitted by voice, the information may not be recognized due to the influence of noise or other disturbances in the work environment, etc. Furthermore, when information is transmitted by vibration, there is a risk that the information may not be perceived by a worker who is moving their body. In contrast, as described above, the information processing device 1 transmits information visually using a head-mounted display. Therefore, according to the information processing device 1, when an emergency occurs concerning the worker, the worker can accurately recognize the status of the issuance of the emergency notification.

[0018] The details of the embodiment will be described below. <First Embodiment> FIG. 2 is a block diagram showing an example of the configuration of the notification system 10 according to the first embodiment. As shown in FIG. 2, the notification system 10 includes worker devices 100_1, 100_2, 100_3, . . . , 100_n and a conductor terminal 200. The worker devices 100_1, 100_2, 100_3, . . . , 100_n each have the same configuration, and in the following description, when referring to these devices without any particular distinction, they will be simply referred to as worker devices 100. There is no limit to the number of worker devices 100. In this embodiment, the notification system 10 includes multiple worker devices 100 because each of multiple workers performing a predetermined task carries a worker device 100. However, the notification system 10 may include only one worker device 100. The worker devices 100 and the conductor terminal 200 are connected to each other so as to be able to communicate with each other wirelessly. Furthermore, the worker devices 100 may also be connected to each other so that they can communicate with each other wirelessly.

[0019] The worker device 100 includes a control device 110, a facepiece 120, an acceleration sensor 130, and a pressure sensor 140. The worker device 100 is carried by a worker. For example, the worker may be a firefighter engaged in firefighting activities, but is not limited to this. For example, the worker may be a police officer, a member of the Self-Defense Forces, a rescue team member, a construction site worker, a worker in any facility, etc. In other words, the worker device 100 can be carried by various workers. The control device 110 and the acceleration sensor 130 are provided at any location on the worker (for example, in a control box attached to a cylinder carried on the worker's back). The facepiece 120 is worn on the worker's head. The pressure sensor 140 is provided in a cylinder (for example, an air cylinder) carried on the worker's back.

[0020] The acceleration sensor 130 detects acceleration in order to detect the movement of the worker carrying the worker device 100 and outputs the detected data to the control device 110 . The pressure sensor 140 detects the pressure inside the cylinder in order to detect the remaining amount of gas (for example, air) inside the cylinder, and outputs the detected data to the control device 110.

[0021] The control device 110 controls the operation of the worker device 100. In particular, the control device 110 controls the transmission and reception of emergency notifications and the display of information on the facepiece 120. The control device 110 corresponds to the information processing device 1 shown in Fig. 1. Details of the control device 110 will be described later.

[0022] Fig. 3 is a diagram showing the configuration of a facepiece. Facepiece 120 includes a transparent cover (face shield) 121. As shown in Fig. 2, facepiece 120 also includes an infrared camera 122, a visible camera 123, a head-mounted display 124, and operation switches 125. The infrared camera 122, the visible camera 123, the head-mounted display 124, and the operation switches 125 are arranged, for example, as shown in Fig. 3. In this embodiment, facepiece 120 includes both infrared camera 122 and visible camera 123 as imaging devices (cameras) that capture images of the environment around the worker wearing facepiece 120, but facepiece 120 may include only one of them.

[0023] The infrared camera 122 captures an image of the environment around the worker based on the infrared light received by the infrared camera 122. The infrared camera 122 outputs the image captured by the infrared camera 122 (hereinafter referred to as the infrared camera image) to the control device 110.

[0024] The visible camera 123 captures an image of the environment around the worker based on visible light received by the visible camera 123. The visible camera 123 outputs the image captured by the visible camera 123 (hereinafter referred to as the visible camera image) to the control device 110.

[0025] The head-mounted display 124 displays any information visible to the worker wearing the facepiece 120. The head-mounted display 124 displays a screen in accordance with the control of the control device 110. Specifically, the head-mounted display 124 displays a screen 80 as shown in FIG. 3. The head-mounted display 124 displays a virtual image of the screen 80 in front of the worker wearing the facepiece 120. Note that in the example of FIG. 3, for the sake of convenience, the front of the facepiece 120 and the screen 80, which is a virtual image, face in the same direction (toward the viewer on the page); however, in reality, the screen 80, which is a virtual image, is displayed so as to face the front of the facepiece 120.

[0026] Specifically, the head-mounted display 124 may have a reflective and translucent member such as a combiner. For example, a screen generated by the control device 110 of the worker device 100 may be projected onto the combiner using a known optical system. This projected screen is reflected (further magnified) by the combiner and reaches the eyes of the worker wearing the facepiece 120. As a result, the worker wearing the facepiece 120 visually recognizes the screen as a magnified virtual image floating in front of him (for example, 1.5 m in front of him). As a result, the image (virtual image) overlaps with the field of view of the worker wearing the facepiece 120, allowing the worker to visually recognize the image (virtual image) with almost no movement of the worker's line of sight. Note that a known optical system can be used for projecting the virtual image, and therefore a description thereof will be omitted. Note that the head-mounted display 124 may display a virtual image by projecting an image onto any portion of the transparent cover 121 of the facepiece 120.

[0027] The screen 80 shown in FIG. 3 includes, for example, a captured image display area 81, a message display area 82, a cylinder display area 83, and an apparatus status display area 84. The captured image display area 81 is an area where an image captured by the imaging device of the facepiece 120 is displayed, for example, an infrared camera image. The message display area 82 is an area where a message to the worker wearing the facepiece 120 is displayed. In this embodiment, when the control device 110 carried by the worker X transmits an emergency notification, a message informing the worker X that the emergency notification has been transmitted is displayed in the message display area 82. Note that the message display area 82 may display a message generated by the commander operating the commander terminal 200 (for example, "Beware of falling objects"). The cylinder display area 83 displays the remaining amount (pressure) of gas (e.g., air) in the cylinder. The apparatus status display area 84 is an area where the status of the apparatus such as the control device 110 is displayed, for example, the remaining battery level and the strength of the radio waves used for communication. 3 is merely an example, and may include an area for displaying information other than the information described above. For example, a map of the worker's activity location may be displayed. This map may be stored in advance in the control device 110, or may be transmitted from the conductor terminal 200 to the worker device 100.

[0028] The operation switch 125 is operated by a worker. The operation switch 125 is, for example, a push button switch. The operation switch 125 is operated by a worker carrying the worker device 100 when an emergency occurs to the worker. For example, in this case, the worker presses and holds the operation switch 125. That is, the worker continues to press the operation switch 125 for a predetermined time or more. This causes an emergency notification to be transmitted, as will be described later. The operation switch 125 may also be used to switch the display mode on the head-mounted display 124. For example, the display mode may be switched when the operation switch 125 is pressed once for less than a predetermined time. Note that the type of operation that needs to be performed on the operation switch 125 is not limited to the above example. For example, an emergency notification may be transmitted when the operation switch 125 is pressed for less than a predetermined time.

[0029] Next, the configuration of the control device 110 will be described. Fig. 4 is a block diagram showing an example of the functional configuration of the control device 110. As shown in Fig. 4, the control device 110 has an image acquisition unit 111, an image transmission unit 112, a switch operation determination unit 113, an operation determination unit 114, a cylinder remaining amount determination unit 115, a notification transmission unit 116, an information reception unit 117, and a display control unit 118.

[0030] The image acquisition unit 111 acquires infrared camera images and visible camera images from the infrared camera 122 and visible camera 123 .

[0031] The video transmission unit 112 transmits the video of the screen 80 displayed on the head-mounted display 124 to the conductor terminal 200. The video transmission unit 112 may transmit both the infrared camera video and the visible camera video. The video transmission unit 112 may also transmit only one of the infrared camera video and the visible camera video, as instructed by the conductor terminal 200.

[0032] The switch operation determination unit 113 determines whether a predetermined operation has been performed on the operation switch 125. In this embodiment, the switch operation determination unit 113 determines whether a first predetermined operation has been performed on the operation switch 125 and whether a second predetermined operation has been performed. Here, the first predetermined operation is an operation performed when an emergency occurs to the worker carrying the worker device 100, and specifically, for example, a long press of the operation switch 125. Furthermore, the second predetermined operation is an operation for switching the display on the head-mounted display 124, and specifically, for example, an operation of briefly pressing the operation switch 125 once.

[0033] The motion determination unit 114 determines whether the motion state of the worker carrying the worker device 100 is a predetermined motion state. Here, the predetermined motion state is the motion of the worker when an abnormality occurs, and specifically, for example, a stationary state that continues for a predetermined period of time or more. The motion determination unit 114 determines the motion state of the worker based on the output from a sensor that detects the worker's movement. In this embodiment, the motion determination unit 114 makes the determination based on the output of the acceleration sensor 130.

[0034] The cylinder remaining amount determination unit 115 determines whether the remaining amount of gas (e.g., air) in a cylinder carried by the worker who carries the worker device 100 has fallen below a predetermined threshold. Specifically, the cylinder remaining amount determination unit 115 determines whether the remaining amount of gas in the cylinder, which is specified based on the output of the pressure sensor 140, has fallen below a predetermined threshold.

[0035] The notification sending unit 116 corresponds to the notification sending unit 2 in FIG. 1 . The notification sending unit 116 sends an emergency notification to the conductor terminal 200 when predetermined conditions are satisfied. In this embodiment, the notification sending unit 116 sends the emergency notification according to the determination results of the switch operation determination unit 113, the action determination unit 114, and the cylinder remaining amount determination unit 115. That is, in this embodiment, one of the predetermined conditions is that a first predetermined operation is performed on the operation switch 125 provided on the protective gear (specifically, the facepiece 120) worn on the head of the worker carrying the worker device 100. Another predetermined condition is that the motion state of the worker carrying the worker device 100 is a predetermined motion state. Another predetermined condition is that the remaining amount of gas in the cylinder carried by the worker carrying the worker device 100 is less than a predetermined threshold. The notification sending unit 116 sends the emergency notification when any of these predetermined conditions is satisfied. Specifically, the notification sending unit 116 transmits information indicating the type of emergency notification and information identifying the sender of the emergency notification. Here, the information indicating the type of emergency notification is information specifying which predetermined condition has been satisfied to cause the emergency notification to be sent. In other words, the information indicating the type of emergency notification is information indicating which of the determinations made by the switch operation determination unit 113, the operation determination unit 114, and the cylinder remaining amount determination unit 115 has triggered the emergency notification. Furthermore, the information identifying the sender of the emergency notification is information specifying which worker the emergency notification notifies of the occurrence of an emergency, and may be, for example, identification information of the worker or identification information of the worker device 100.

[0036] The information receiving unit 117 receives information transmitted from the conductor terminal 200. The information receiving unit 117 may also receive information transmitted from other worker devices 100. In this embodiment, the information receiving unit 117 receives a response signal from the conductor terminal 200 that has received the emergency notification transmitted by the notification transmitting unit 116. As will be described later, this response signal is transmitted from the conductor terminal 200 when the conductor, who has confirmed via the conductor terminal 200 that an emergency notification has been issued for the worker, operates the conductor terminal 200. Furthermore, in this embodiment, the information receiving unit 117 receives from the conductor terminal 200 an emergency notification transmitted from another worker device 100. This is because, as will be described later, when the conductor terminal 200 receives an emergency notification from any worker device 100, the conductor terminal 200 forwards the emergency notification to all other worker devices 100. In this way, in this embodiment, the information receiving unit 117 receives an emergency notification that notifies the occurrence of an emergency for a worker carrying another worker device 100.

[0037] The display control unit 118 controls the head mounted display 124 to display a screen 80. The display control unit 118 controls the head mounted display 124 to display, for example, the screen 80 including the image (for example, an infrared camera image) acquired by the image acquisition unit 111. As described above, the display control unit 118 may also acquire the remaining amount of gas in the cylinder and the status of the device, and control the display of these.

[0038] The display control unit 118 corresponds to the display control unit 3 in FIG. 1 . Therefore, the display control unit 118 further controls so that information related to the emergency notification is displayed on the head-mounted display 124. When the notification sending unit 116 sends an emergency notification, the display control unit 118 controls so that information related to this emergency notification is displayed. Specifically, the display control unit 118 controls so that information indicating that the notification sending unit 116 has sent the emergency notification is displayed on the head-mounted display 124. For example, in this case, the display control unit 118 controls so that information indicating the type of the emergency notification sent by the notification sending unit 116 is displayed in the message display area 82.

[0039] FIG. 5 is a display example of the head-mounted display 124 when the operation switch 125 is operated and an emergency notification is sent. In this example, the word "emergency" is displayed in the message display area 82 as information indicating the type of emergency notification. FIG. 6 is a display example of the head-mounted display 124 when an emergency notification is sent because the worker's movement is in a predetermined movement state. In this example, the word "stationary alarm" is displayed in the message display area 82 as information indicating the type of emergency notification. FIG. 7 is a display example of the head-mounted display 124 when an emergency notification is sent because the remaining amount of gas in the cylinder has fallen below a threshold. In this example, the word "cylinder remaining amount" is displayed in the message display area 82 as information indicating the type of emergency notification. Note that the display control unit 118 may perform such display in an area other than the message display area 82.

[0040] In this way, when the notification sending unit 116 sends an emergency notification, information about this emergency notification is displayed, allowing the worker to visually recognize that the emergency notification has been sent from the worker device 100 that the worker carries. Furthermore, when the information receiving unit 117 receives a response signal from the destination of the emergency notification (i.e., the conductor terminal 200), the display control unit 118 controls the display of the information about the emergency notification sent by the notification sending unit 116 to end. This allows the worker to visually recognize that the emergency notification has been acknowledged by the conductor.

[0041] Furthermore, when the information receiving unit 117 receives an emergency notification informing a worker carrying another worker device 100 of the occurrence of an emergency, the display control unit 118 performs control to display information related to this emergency notification. That is, the display control unit 118 performs control to display information indicating the emergency notification informing a worker carrying another worker device 100 of the occurrence of an emergency on the head-mounted display 124. For example, in this case, the display control unit 118 displays information indicating the type of the received emergency notification and information identifying the sender of the emergency notification in the captured image display area 81. When displaying the information related to the emergency notification in the captured image display area 81, the display control unit 118 performs control to display the information superimposed on the infrared camera image or the visible camera image.

[0042] 8 to 10 are display examples on the head-mounted display 124 of an emergency notification informing a worker (team member A) carrying another worker device 100 of the occurrence of an emergency. FIGS. 8 to 10 are display examples on the head-mounted display 124 of a worker (team member) other than team member A. FIG. 8 is a display example on the head-mounted display 124 when team member A operates the operation switch 125 to send an emergency notification. In this example, the captured image display area 81 displays the word "emergency" as information indicating the type of emergency notification and the word "team member A" as information identifying the sender of the emergency notification. FIG. 9 is a display example on the head-mounted display 124 when an emergency notification is sent because team member A's movement is in a predetermined movement state. In this example, the captured image display area 81 displays the word "stationary warning" as information indicating the type of emergency notification and the word "team member A" as information identifying the sender of the emergency notification. 10 is a display example of the head-mounted display 124 when an emergency notification is sent because the remaining amount of gas in the cylinder of team member A has fallen below a threshold. In this example, the captured image display area 81 displays the characters "Remaining cylinder amount" as information indicating the type of emergency notification, and the characters "Team member A" as information identifying the sender of the emergency notification. Note that the display control unit 118 may also display information related to the received emergency notification in an area other than the captured image display area 81.

[0043] By performing such display control, a worker carrying the worker device 100 can visually recognize that an emergency has occurred for another worker. This allows the worker to quickly head to the worker in the emergency situation to check the situation or provide rescue. Furthermore, when a predetermined operation for switching the display is performed on the operation switch 125, the display control unit 118 controls the information receiving unit 117 to terminate the display of information related to the emergency notification received by the information receiving unit 117. That is, when the switch operation determination unit 113 detects a second predetermined operation on the operation switch 125, the display control unit 118 controls the information receiving unit 117 to terminate the display of information related to the emergency notification received by the information receiving unit 117. This allows the worker to freely terminate the display of information related to the emergency notification. In particular, even when information related to the emergency notification is displayed superimposed on the camera image, the worker can prioritize viewing the display of the camera image.

[0044] Next, the conductor terminal 200 will be described. The conductor terminal 200 is a terminal operated by a conductor who directs the workers. As shown in FIG. 2, the conductor terminal 200 has a touch panel 210, a display 220, and a control device 230. The touch panel 210 is an input device operated by the conductor, and is arranged so as to cover the display surface of the display 220. The display 220 is, for example, a display with a touch panel 210. A display with a touch panel is also called a touch screen display.

[0045] 11 is a block diagram showing an example of the functional configuration of the control device 230 of the conductor terminal 200. As shown in FIG. 11, the control device 230 has an input accepting unit 231, an information receiving unit 232, a display control unit 233, and an information transmitting unit 234.

[0046] The input receiving unit 231 receives input via the touch panel 210. Therefore, it can also be said that the input receiving unit 231 receives instructions from the conductor.

[0047] The information receiving unit 232 receives information transmitted from the worker device 100. In particular, in this embodiment, the information receiving unit 232 receives an emergency notification transmitted from the worker device 100.

[0048] The display control unit 233 controls the display 220 to display a screen 90. FIG. 12 is a schematic diagram showing an example of the screen 90 displayed under the control of the display control unit 233. As shown in FIG. 12, for example, images from the head-mounted displays 124 of each worker (worker A, worker B, worker C, and worker D) are arranged on the screen 90. This allows the commander to check the status of each worker. Furthermore, when the information receiving unit 232 receives an emergency notification from the worker device 100, the display control unit 233 controls the display 220 to display the received emergency notification. Specifically, the display control unit 233 controls the display 220 to display an icon 91 indicating that an emergency notification has been received. The example shown in FIG. 12 shows an example of the screen 90 when an emergency notification has been received from the worker device 100 of worker A, and an icon 91 indicating that an emergency notification about worker A has been received is displayed. When the conductor recognizes the emergency notification for team member A, the conductor touches icon 91 on the touch panel 210. When icon 91 is touched, the information transmission unit 234 transmits a response signal to the worker device 100 of team member A. As a result, as described above, the display of the emergency notification disappears from the head-mounted display 124 of the worker device 100 of team member A. Note that the display control unit 233 may perform control so as to display, in addition to icon 91, information indicating the type of emergency notification or information identifying the sender of the emergency notification.

[0049] The information transmitting unit 234 transmits information to the worker device 100. In this embodiment, in particular, the information transmitting unit 234 transmits the above-mentioned response signal to the worker device 100 that transmitted the emergency notification. Furthermore, the information transmitting unit 234 transfers the emergency notification received by the information receiving unit 232 to worker devices 100 other than the worker device 100 that transmitted the emergency notification. In this embodiment, the information transmitting unit 234 transfers the information to all worker devices 100 other than the worker device 100 that transmitted the emergency notification. Note that the information transmitting unit 234 that performs such processing may also be referred to as a forwarding unit. Furthermore, the information transmitting unit 234 may transmit information (e.g., a message from a conductor to a worker) corresponding to the input received by the input receiving unit 231.

[0050] Next, a description will be given of the hardware configuration of the control device 110 of the worker device 100. Fig. 13 is a schematic diagram showing an example of the hardware configuration of the control device 110. As shown in Fig. 13, the control device 110 includes a network interface 151, a memory 152, and a processor 153.

[0051] The network interface 151 is used to communicate with any device, such as the conductor terminal 200 and other worker devices 100. The network interface 151 may include, for example, a network interface card (NIC).

[0052] The memory 152 is configured, for example, by a combination of volatile memory and non-volatile memory. The memory 152 is used to store programs executed by the processor 153, data used for various processes of the worker device 100, and the like.

[0053] The processor 153 reads and executes a program from the memory 152 to perform processing of each component shown in Fig. 4. The processor 153 may be, for example, a microprocessor, an MPU (Micro Processor Unit), or a CPU (Central Processing Unit). The processor 153 may include multiple processors.

[0054] In this way, the worker device 100 has the functionality of a computer. Although not shown, the control device 230 of the conductor terminal 200 also has a similar configuration as shown in Fig. 13. That is, the conductor terminal 200 also has a processor and memory, and has the functionality of a computer. Therefore, the processing of each component of the control device 230 of the conductor terminal 200 shown in Fig. 11 is realized by the execution of a program by the processor.

[0055] The program includes instructions (or software code) that, when loaded into a computer, cause the computer to perform one or more functions described in the embodiments. The program may be stored in a non-transitory computer-readable medium or a tangible storage medium. By way of example and not limitation, computer-readable media or tangible storage media include random-access memory (RAM), read-only memory (ROM), flash memory, solid-state drive (SSD) or other memory technologies, CD-ROM, digital versatile disc (DVD), Blu-ray® disc or other optical disk storage, magnetic cassette, magnetic tape, magnetic disk storage or other magnetic storage devices. The program may also be transmitted on a transitory computer-readable medium or communication medium. By way of example and not limitation, transitory computer-readable media or communication media include electrical, optical, acoustic, or other forms of propagated signals.

[0056] Next, an operation of transmitting and displaying an emergency notification in the worker device 100 will be described. Fig. 14 is a flowchart showing an example of the flow of the operation of the worker device 100. Below, an example of the operation of the worker device 100 will be described with reference to Fig. 14. Note that the order of processing of each step in the flowchart shown in Fig. 14 can be changed as appropriate as long as no technical contradiction occurs.

[0057] In step S100, the switch operation determination unit 113 determines whether a predetermined operation, i.e., an operation to be performed when an emergency occurs to the worker carrying the worker device 100, has been performed on the operation switch 125. If such an operation has not been performed, the process proceeds to step S101. On the other hand, if such an operation has been performed, the process proceeds to step S103.

[0058] In step S101, the motion determination unit 114 determines whether the motion state of the worker carrying the worker device 100 is a predetermined motion state. That is, the motion determination unit 114 determines whether the motion state of the worker is stationary. If the motion state of the worker is not a predetermined motion state, the process proceeds to step S102. On the other hand, if the motion state of the worker is a predetermined motion state, the process proceeds to step S103.

[0059] In step S102, the cylinder remaining amount determination unit 115 determines whether the remaining amount of gas (e.g., air) in the cylinder carried by the worker who carries the worker device 100 is less than a predetermined threshold. If the remaining amount is equal to or greater than the predetermined threshold, the process proceeds to step S107. On the other hand, if the remaining amount is less than the predetermined threshold, the process proceeds to step S103.

[0060] In step S103, the notification sending unit 116 sends an emergency notification to the conductor terminal 200 to notify the conductor of the occurrence of an emergency situation regarding the worker carrying the worker device 100. After step S103, the process proceeds to step S104.

[0061] In step S104, the display control unit 118 controls the information related to the emergency notification transmitted in step S103 to be displayed on the head mounted display 124. As a result, information such as that shown in Fig. 5, 6, or 7 is displayed on the head mounted display 124. After step S104, the process proceeds to step S105.

[0062] In step S105, the display control unit 118 determines whether or not the information receiving unit 117 has received a response signal from the conductor terminal 200. This step is repeated until a response signal is received from the conductor terminal 200, and when a response signal is received from the conductor terminal 200, that is, when the conductor recognizes the emergency notification transmitted in step S103, the process proceeds to step S106.

[0063] In step S106, the display control unit 118 performs control to terminate the display of the information relating to the emergency notification that was displayed in step S104, and the process then returns to step S100.

[0064] On the other hand, in step S107, the display control unit 118 determines whether or not the information receiving unit 117 has received an emergency notification from another worker device 100. If an emergency notification from another worker device 100 has been received, the process proceeds to step S108, and if not, the process returns to step S100.

[0065] In step S108, the display control unit 118 controls the information related to the emergency notification received in step S107 to be displayed on the head mounted display 124. As a result, information such as that shown in Fig. 8, 9, or 10 is displayed on the head mounted display 124. After step S108, the process proceeds to step S109.

[0066] In step S109, the switch operation determination unit 113 determines whether or not an operation has been performed on the operation switch 125 to switch the display of the head-mounted display 124. This step is repeated until such an operation is performed, and when such an operation is performed, the process proceeds to step S110.

[0067] In step S110, the display control unit 118 performs control to terminate the display of the information relating to the emergency notification that was displayed in step S108, and then the process returns to step S100.

[0068] The first embodiment has been described above. According to the first embodiment, as described above, information is visually transmitted using the head-mounted display 124. Therefore, when an emergency occurs for the worker, the worker can accurately recognize the status of the issuance of the emergency notification. In the above description, the notification sending unit 116 sends the emergency notification to the conductor terminal 200, but it may also send the emergency notification to other worker devices 100. That is, the emergency notification sent from the worker device 100 may be directly transmitted to other worker devices 100. In this case, the forwarding process of the emergency notification in the conductor terminal 200 may be omitted. In the above description, the emergency notification is also sent to other worker devices 100, but it may also be sent to only the conductor terminal 200. That is, the conductor terminal 200 does not need to forward the emergency notification to worker devices 100 other than the worker device 100 that sent the emergency notification.

[0069] <Embodiment 2> Next, a second embodiment will be described. This embodiment differs from the first embodiment in that, when an emergency notification notifying an occurrence of an emergency regarding a worker carrying another worker device 100 is received, the display control unit 118 performs the following control. That is, in this embodiment, when an emergency notification notifying an occurrence of an emergency regarding a worker carrying another worker device 100 is received, the display control unit 118 controls the head-mounted display 124 to display an image captured by a camera carried by the worker. That is, the display control unit 118 controls the head-mounted display 124 to display an infrared camera image or a visible camera image of the worker in whom the emergency has occurred. Note that in this case, the display control unit 118 may also perform control to display information indicating the type of the received emergency notification and information identifying the sender of the emergency notification, as in the first embodiment.

[0070] In this embodiment, to enable the above-described display, when the information transmitting unit 234 of the conductor terminal 200 transfers the emergency notification to each worker device 100, it also transmits the infrared camera image or the visible camera image acquired from the sender of the emergency notification to each worker device 100. Note that when the emergency notification transmitted from one worker device 100 is directly transmitted to another worker device 100, the infrared camera image or the visible camera image may also be directly transmitted from the worker device 100 that transmitted the emergency notification to the other worker device 100.

[0071] 15 to 17 show display examples on the head-mounted display 124 of an emergency notification informing a worker (worker A) carrying another worker device 100 of the occurrence of an emergency in the second embodiment. FIGS. 15 to 17 show display examples on the head-mounted display 124 of a worker (worker) other than worker A. FIG. 15 shows a display example on the head-mounted display 124 when worker A operates the operation switch 125 to transmit an emergency notification. FIG. 16 shows a display example on the head-mounted display 124 when worker A's movement is in a predetermined movement state and an emergency notification is transmitted. FIG. 17 shows a display example on the head-mounted display 124 when an emergency notification is transmitted because the remaining amount of gas in worker A's cylinder has fallen below a threshold. As shown in FIGS. 15 to 17, the display control unit 118 according to the present embodiment displays, for example, a camera video 85 of worker A in the captured image display area 81. 15 to 17, the display control unit 118 controls the display of the camera image 85 of team member A so as to be superimposed on the infrared camera image or visible camera image of the worker who received the emergency notification from another worker. The display control unit 118 may also display the camera image 85 of team member A in an area other than the captured image display area 81.

[0072] By performing such display control, when an emergency occurs to another worker, a worker carrying worker device 100 can check the video captured by the camera of the worker in question. Therefore, the worker who views the video can confirm the location of the worker in question and the situation of the worker in question (for example, whether he / she has collapsed or is active). This is expected to reduce the time required to rescue the worker in question.

[0073] Also in the present embodiment, when a predetermined operation for switching the display is performed on operation switch 125, display control unit 118 controls information receiving unit 117 to terminate the display of information related to the emergency notification received. That is, when switch operation determination unit 113 detects a second predetermined operation on operation switch 125, display control unit 118 controls information receiving unit 117 to terminate the display of information related to the emergency notification received. In this case, display control unit 118 may terminate only the display of the camera image, may terminate only the display of the text information, or may terminate the display of both.

[0074] <Third Embodiment> Next, a third embodiment will be described. This embodiment differs from the first embodiment in that an emergency notification is sent only to worker devices 100 that are close to the sender of the emergency notification, among worker devices 100 other than the sender of the emergency notification. Below, a description of the same configuration and processing as in the first embodiment will be omitted as appropriate, and differences from the first embodiment will be specifically described.

[0075] The configuration according to the third embodiment differs from that of the first embodiment in that the control device 110 of the worker device 100 is replaced with a control device 110a, and the control device 230 of the conductor terminal 200 is replaced with a control device 230a.

[0076] FIG. 18 is a block diagram showing an example of the functional configuration of the control device 110a. FIG. 19 is a block diagram showing an example of the functional configuration of the control device 230a. As shown in FIG. 18, the control device 110a differs from the control device 110 shown in FIG. 4 in that it further includes a location management unit 119. Similarly, the control device 230a differs from the control device 230 shown in FIG. 11 in that it further includes a location management unit 235. Note that the processing of each component of the control device 110a is also realized, for example, by the processor 153 reading and executing a program from the memory 152. Similarly, the processing of each component of the control device 230a is also realized, for example, by the processor reading and executing a program from the memory.

[0077] The location management unit 119 of the control device 110a and the location management unit 235 of the control device 230a manage the location information of each worker (the location information of the worker device 100 carried by each worker). The location management unit 119 and the location management unit 235 collectively manage the location information of each worker acquired by any method. For example, this location information may be location information acquired using a global navigation satellite system (GNSS) such as a global positioning system (GPS), or may be location information acquired using any indoor location positioning technology such as beacon positioning, Wi-Fi positioning, or ultra wide band (UWB) positioning.

[0078] In this embodiment, the information transmitting unit 234 of the control device 230a (conductor terminal 200) differs from the first embodiment in the process of transferring an emergency notification received by the information receiving unit 232 to worker devices 100 other than the worker device 100 that sent the emergency notification. In this embodiment, the information transmitting unit 234 transfers the emergency notification only to worker devices 100 that are located near the worker device 100 that sent the emergency notification. That is, the information transmitting unit 234 transfers the emergency notification to worker devices 100 carried by workers that are located within a predetermined range from the worker carrying the worker device 100 that sent the emergency notification. In other words, the information transmitting unit 234 transfers the emergency notification to worker devices 100 that are located within a predetermined range from the point at which the emergency notification was sent (the location of the worker device 100 that sent the emergency notification). To this end, when transferring the emergency notification, the information transmitting unit 234 refers to the locations of each worker managed by the location management unit 235, and identifies the worker device 100 to which the emergency notification is to be transferred. This makes it possible to notify only workers who are close to the worker in question of an emergency. In other words, it is possible to notify only workers who can efficiently rush to the worker in question. Therefore, workers who are far from the worker in question can concentrate on their original work.

[0079] In the worker device 100 that receives an emergency notification about another worker from the conductor terminal 200, the display control unit 118 controls the head-mounted display 124 to display information about the emergency notification, as in the first embodiment. The display control unit 118 may display a map indicating the location of each worker on the head-mounted display 124 based on the location information of each worker managed by the location management unit 119. In this case, the display control unit 118 may display the location of the worker in an emergency differently from the locations of the other workers, so that the location of the worker in an emergency can be identified. For example, the display control unit 118 may change the color of a point on the map indicating the location of a worker in an emergency to a different color from the color of a point indicating the location of a worker in a non-emergency situation. Furthermore, for example, the display control unit 118 may change the shape of a point on the map indicating the location of a worker in an emergency to a different shape from the shape of a point indicating the location of a worker in a non-emergency situation. Furthermore, for example, the display control unit 118 may change the size of a point on the map indicating the location of a worker in an emergency to a different size from the size of a point indicating the location of a worker in a non-emergency situation. The display control unit 118 may vary only one of the shape, color, and size of the dots, or may vary two or more of these. These are merely examples, and any display may be used to distinguish the location of a worker in an emergency from the locations of workers in whom an emergency has occurred. This makes it possible to easily recognize the location of a worker in an emergency. Furthermore, any display may be used to distinguish the location of a worker carrying the head-mounted display 124, which is displayed under the control of the display control unit 118, from the locations of other workers. This allows the worker to recognize their own location and the locations of other workers in a distinguishable manner.

[0080] 20 to 22 are display examples on the head mounted display 124 of an emergency notification informing a worker (worker A) carrying another worker device 100 of the occurrence of an emergency in the third embodiment. The emergency notification from worker A is transmitted, for example, to workers B and C who are near worker A. FIGS. 20 to 22 are display examples on the head mounted display 124 of a worker (worker C) other than worker A. FIG. 20 is a display example on the head mounted display 124 of worker C when worker A operates the operation switch 125 to transmit an emergency notification. FIG. 21 is a display example on the head mounted display 124 of worker C when an emergency notification is transmitted because worker A is in a predetermined operating state. FIG. 22 is a display example on the head mounted display 124 of worker C when an emergency notification is transmitted because the remaining amount of gas in worker A's cylinder falls below a threshold. 20 to 22, the display control unit 118 of the worker device 100 carried by worker C indicates the position of worker C on the map 86 by a point having a first characteristic (for example, color, shape, or size). The display control unit 118 then indicates the position of worker A on the map 86 by a point having a second characteristic, and indicates the positions of workers other than worker C and worker A on the map 86 by a point having a third characteristic. In the example shown in FIGS. 20 to 22, the map 86 is displayed in the captured image display area 81. That is, in the example shown in FIGS. 20 to 22, the display control unit 118 controls the display of the map 86 so that it is superimposed on the infrared camera image or visible camera image of worker C. The display control unit 118 may also display the map 86 in an area other than the captured image display area 81.

[0081] The third embodiment has been described above. According to this embodiment, as described above, it is possible to notify only workers who are close to a worker of an emergency. Therefore, it is possible to notify only workers who can efficiently rush to the worker in need of the emergency. In this embodiment, the display control unit 118 has been described as controlling the display of location information of each worker. However, if the display control unit 118 does not control the display of location information of each worker, the location management unit 119 may be omitted. Also, in this embodiment, the emergency notification transmitted from the worker device 100 is forwarded to each worker device 100 by the conductor terminal 200. However, the emergency notification transmitted from the worker device 100 may be directly transmitted to another worker device 100. In this case, the notification transmission unit 116 of the worker device 100 transmits the emergency notification to other worker devices 100 carried by workers present within a predetermined range. In other words, the notification transmitter 116 of the worker device 100 transmits the emergency notification to worker devices 100 within a predetermined range from the point of transmission of the emergency notification (the position of the worker device 100 that sent the emergency notification). Furthermore, this embodiment and embodiment 2 may be combined. That is, in this embodiment, as in embodiment 2, an image captured by a camera of a worker in an emergency situation may be displayed on the head-mounted display 124.

[0082] The present invention is not limited to the above-described embodiment, and modifications can be made as appropriate without departing from the spirit and scope of the present invention. For example, in the above-described embodiment, the operation of the operation switch 125, the worker's motion state, and the remaining amount of gas in the cylinder are used as triggers for transmitting an emergency notification. However, only one of these may be used as a trigger for transmitting an emergency notification. In this case, the worker device 100 does not need to include all of the operation switch 125, the acceleration sensor 130, and the pressure sensor 140. Similarly, the control device 110 (control device 110a) of the worker device 100 does not need to include all of the switch operation determination unit 113, the motion determination unit 114, and the cylinder remaining amount determination unit 115. Furthermore, in the above-described embodiment, the control device 110 (control device 110a) has been described as a device separate from the face piece 120, but the control device 110 (control device 110a) may be included in the face piece 120. In this way, the face piece 120 may have the functions of the control device 110 or the control device 110a.
