Each embodiment will be described below with reference to the accompanying drawings. Note that in this specification and the drawings, components having substantially the same functional configuration are designated by the same reference numerals to avoid redundant description.

[First embodiment]
<System configuration of disaster action support system>
First, a system configuration of a disaster action support system according to a first embodiment will be described. Fig. 1 is a diagram showing an example of the system configuration of a disaster action support system. A disaster action support system 100 is applied to various manufacturing sites such as chemical plants.

As shown in FIG. 1, the disaster action support system 100 includes a disaster monitoring device 110, wearable devices 120_1 to 120_n, an information provision system 130, and a server device 140. In the disaster action support system 100, the disaster monitoring device 110, the wearable devices 120_1 to 120_n, the information provision system 130, and the server device 140 are communicatively connected via a network 150.

The disaster monitoring device 110 is a device that detects disasters. When the disaster monitoring device 110 detects a disaster, it transmits disaster information (location of the disaster, details of the disaster, etc.) to the server device 140 via the network 150.

Note that while the example in FIG. 1 shows only one disaster monitoring device 110, the Fire Service Act Enforcement Ordinance stipulates that one disaster monitoring device 110 must be installed in a security zone of 600 square meters or less. For this reason, the disaster action support system 100 applied to various manufacturing sites such as chemical plants is also required to install a number of disaster monitoring devices 110 in accordance with the Enforcement Ordinance. Note that a security zone refers to the smallest unit of zone in which an area where a fire has occurred can be distinguished from other areas.

Wearable devices 120_1 to 120_n are examples of disaster action support devices, and are devices that can be worn by multiple field workers working at a manufacturing site. At least after a disaster is detected (or after a disaster is detected), wearable devices 120_1 to 120_n transmit information acquired by the devices themselves (referred to as "field information") to server device 140 via network 150.

In addition, when a disaster is detected by the disaster monitoring device 110, the wearable devices 120_1 to 120_n receive from the server device 140 the disaster information transmitted from the disaster monitoring device 110 to the server device 140.

In addition, when wearable devices 120_1 to 120_n detect a disaster on their own devices, they transmit disaster information to server device 140.

In addition, when wearable devices 120_1 to 120_n acquire disaster information, they also acquire disaster response instructions (initial response instructions) in the event of a disaster that corresponds to the work process of the on-site work.

In this way, when wearable devices 120_1 to 120_n acquire disaster information, they acquire initial response instructions from server device 140. This allows each field worker wearing wearable device 120_1 to 120_n to take appropriate action when a disaster occurs.

In addition, if a certain amount of time has passed since the occurrence of a disaster and it is determined that the situation at the manufacturing site has changed and that the disaster response instructions need to be changed, wearable devices 120_1 to 120_n receive disaster response instructions according to the situation at the manufacturing site. This allows each on-site worker wearing wearable device 120_1 to 120_n to take appropriate action according to the situation at the manufacturing site, even if the situation at the manufacturing site has changed after the occurrence of a disaster.

The information providing system 130 is an example of an external system, and transmits meteorological information about the surroundings of the manufacturing site to the server device 140 via the network 150. The meteorological information about the surroundings of the manufacturing site includes information on wind direction, wind speed, weather (sunny, cloudy, rainy), solar radiation, earthquakes, tsunamis, typhoons, etc.

A disaster information analysis program is installed in the server device 140, and by executing this program, the server device 140 functions as a receiving unit 141, an acquiring unit 142, a generating unit 143, and a transmitting unit 144.

The receiving unit 141 receives information transmitted from the disaster monitoring device 110, the wearable devices 120_1 to 120_n, and the information providing system 130 via the network 150, and notifies the acquiring unit 142 of the information as received information. The received information notified by the receiving unit 141 includes disaster information, on-site information, weather information, etc.

The acquisition unit 142 acquires the received information notified from the receiving unit 141, and notifies the generation unit 143 of the disaster information, on-site information, and weather information contained in the acquired received information.

When disaster information is notified from the acquisition unit 142, the generation unit 143 notifies the transmission unit 144 of the disaster information. The generation unit 143 also refers to the disaster response information storage unit 145, selects disaster response instructions corresponding to the work process of the on-site work from the disaster information, and notifies the transmission unit 144 as initial response instructions. The disaster response information storage unit 145 stores multiple disaster response instructions corresponding to the work process of the on-site work. Note that when selecting disaster response instructions from the disaster information, the generation unit 143 refers to the worker information storage unit 146, and selects disaster response instructions suitable for the attribute information of each on-site worker.

When the generating unit 143 receives on-site information and weather information from the acquiring unit 142, the generating unit 143 analyzes the on-site information and weather information, grasps the situation at the manufacturing site, and determines whether or not the current disaster response instructions need to be changed. When the generating unit 143 determines that the situation at the manufacturing site has changed and that the disaster response instructions need to be changed, the generating unit 143 refers to the disaster response information storage unit 145, selects a disaster response instruction (a disaster response instruction different from the initial response instruction) according to the situation at the manufacturing site, and notifies the transmitting unit 144.

When disaster information is notified by the generation unit 143, the transmission unit 144 transmits the disaster information to the wearable devices 120_1 to 120_n via the network 150. Note that when the disaster information notified by the generation unit 143 is disaster information detected by any of the wearable devices, the transmission unit 144 transmits the disaster information to wearable devices other than the wearable device.

In addition, when a disaster response instruction is notified from the generation unit 143, the transmission unit 144 transmits it to the wearable devices 120_1 to 120_n via the network 150.

In this way, the disaster action support system 100:
・When a disaster occurs, disaster response instructions according to the work process of the on-site work are selected from the disaster information and sent as initial response instructions.
- After a disaster occurs, the situation at the manufacturing site is monitored, and if it is determined that the situation at the manufacturing site has changed and the current disaster response instructions need to be changed, disaster response instructions appropriate to the situation at the manufacturing site are selected and sent.

As a result, the disaster action support system 100 makes it possible to give instructions according to the situation at the manufacturing site after a disaster occurs.

<Hardware configuration of wearable device>
Next, the hardware configuration of the wearable devices 120_1 to 120_n will be described. In this embodiment, the wearable devices 120_1 to 120_n worn by the multiple field workers each have the same hardware configuration, so only the wearable device 120_1 will be described here.

Figure 2 is a diagram showing an example of the hardware configuration of a wearable device. Wearable device 120_1 has a glasses-type external configuration, and as shown in Figure 2, has a processor 201, memory 202, auxiliary storage device 203, communication device 204, and GPS (Global Positioning System) device 205. Wearable device 120_1 also has an audio input device 206, an audio output device 207, a display device 208, an imaging device 209, a connection device 210, and a short-range wireless communication device 211. The hardware components constituting wearable device 120_1 are connected to each other via a bus 220.

The processor 201 has various computing devices such as a CPU (Central Processing Unit). The processor 201 reads various programs (such as a disaster information collection program described below) onto the memory 202 and executes them.

The memory 202 has a primary storage device such as a ROM (Read Only Memory) or a RAM (Random Access Memory). The processor 201 and the memory 202 form a so-called computer (also called a "control unit"), and the processor 201 executes various programs read onto the memory 202, causing the computer to realize various functions.

The auxiliary storage device 203 stores various programs and various information (e.g., disaster response instructions) used when the various programs are executed by the processor 201.

The communication device 204 is a communication device for transmitting and receiving various information (e.g., disaster information, disaster response instructions, and on-site information) between the server device 140. The GPS device 205 detects the location information of the wearable device 120_1.

Note that each device, from the processor 201 to the GPS device 205, is built into a location that corresponds to the front frame of the glasses, for example.

The voice input device 206 detects voice information such as the voice of the on-site worker wearing the wearable device 120_1, ambient sounds at the manufacturing site, and the voices of surrounding on-site workers. The voice input device 206 is placed, for example, at a position equivalent to the temples of glasses.

The audio output device 207 is a device that notifies, for example, various information received from the server device 140 by audio output to a field worker wearing the wearable device 120_1.

The display device 208 is, for example, a device that notifies the field worker wearing the wearable device 120_1 of various information received from the server device 140 by displaying an image. The display device 208 is, for example, disposed at a position corresponding to the lens portion of glasses.

The imaging device 209 captures the surroundings of the field worker wearing the wearable device 120_1 and generates image information.

The connection device 210 is a connection device used to connect various attached sensors to the wearable device 120_1. The various attached sensors connected via the connection device 210 include a sensor that detects a disaster and outputs disaster information, a sensor that detects and outputs biometric information of a field worker wearing the wearable device 120_1, and the like.

The short-range wireless communication device 211 is a wireless device for performing short-range wireless communication between the field worker wearing the wearable device 120_1 and other field workers wearing wearable devices that are present in the vicinity of the field worker wearing the wearable device 120_1. The short-range wireless communication device 211 is built into a location that corresponds to the front frame of glasses, for example.

<Functional configuration of wearable device>
Next, the functional configuration of the wearable device will be described. In this embodiment, since the wearable devices 120_1 to 120_n worn by the multiple field workers each have the same functional configuration, only the wearable device 120_1 will be described here.

As described above, a disaster information collection program is installed in wearable device 120_1, and by executing this program, wearable device 120_1 realizes various functions.

Figure 3 is a diagram showing an example of the functional configuration of a wearable device. As shown in Figure 3, wearable device 120_1 realizes various functions including a disaster information acquisition unit 310, a disaster information notification unit 320, an alarm unit 330, a receiving unit 340, an on-site information acquisition unit 350, a peripheral device determination unit 360, and a transmitting unit 370.

Of these, the disaster information acquisition unit 310 acquires disaster information (such as the location of the disaster, details of the disaster, etc.) when a disaster is detected by any of the various attached sensors connected via the connection device 210. Examples of disaster information detected by attached sensors include disaster information output by a sensor that detects a specific harmful gas when the specific harmful gas is detected by the sensor.

The disaster information acquisition unit 310 also notifies the disaster information notification unit 320, the on-site information acquisition unit 350, and the transmission unit 370 of the acquired disaster information.

When disaster information is notified by the disaster information acquisition unit 310, the disaster information notification unit 320 notifies the alert unit 330 and transmits the information to the server device 140. This allows the server device 140 to notify the worker managing the entire disaster action support system 100 (a worker remote from the perspective of the wearable device 120_1) that a disaster has occurred. In addition, the server device 140 can transmit disaster information to wearable devices other than the wearable device 120_1, thereby notifying field workers other than the field worker wearing the wearable device 120_1 that a disaster has occurred.

When disaster information is notified, the notification unit 330 notifies the field worker wearing the wearable device 120_1 that a disaster has occurred. Furthermore, when disaster information is notified by the disaster information notification unit 320, the notification unit 330 refers to the disaster response information storage unit 380. As a result, the notification unit 330 selects disaster response instructions corresponding to the work process of the field work from the notified disaster information, and notifies the field worker wearing the wearable device 120_1. Note that the disaster response information storage unit 380 stores multiple disaster response instructions corresponding to the work process of the field work.

In addition, when disaster information is notified by the receiving unit 340, the notification unit 330 subsequently obtains disaster response instructions from the receiving unit 340 and notifies the field worker wearing the wearable device 120_1.

When the receiving unit 340 receives disaster information from the server device 140, it notifies the notification unit 330, the on-site information acquisition unit 350, and the transmission unit 370. Furthermore, when the receiving unit 340 receives a disaster response instruction from the server device 140, it notifies the notification unit 330. Note that the receiving unit 340 can be said to have the function of a disaster information acquisition unit in that it acquires disaster information from outside the wearable device 120_1.

The site information acquisition unit 350 acquires the location information detected by the GPS device 205. The location information detected by the GPS device 205 represents the current location information of the site worker wearing the wearable device 120_1.

The on-site information acquisition unit 350 also acquires audio information detected by the audio input device 206. As described above, the audio information detected by the audio input device 206 includes the voice of the on-site worker wearing the wearable device 120_1, ambient sounds at the manufacturing site, the voices of surrounding on-site workers, and the like. The on-site information acquisition unit 350 that acquires audio information is an example of a second on-site information acquisition unit.

The site information acquisition unit 350 also acquires image information captured by the imaging device 209. As described above, the image information captured by the imaging device 209 includes images of the surroundings of the site worker wearing the wearable device 120_1. The site information acquisition unit 350 that acquires the image information is an example of a first site information acquisition unit.

In addition, the on-site information acquisition unit 350 acquires biometric information of the on-site worker wearing the wearable device 120_1, the biometric information being detected by any one of the various attached sensors connected via the connection device 210.

In addition, the site information acquisition unit 350 acquires peripheral device information from the peripheral device determination unit 360. The peripheral device information includes information about wearable devices worn by other site workers that are present in the vicinity of the site worker wearing the wearable device 120_1.

The peripheral device determination unit 360 is an example of a determination unit, and determines whether or not there are other wearable devices in the vicinity from the short-range wireless communication radio waves received by the short-range wireless communication device 211. Furthermore, when the peripheral device determination unit 360 determines that there is a wearable device worn by another on-site worker, it notifies the on-site information acquisition unit 350 of the peripheral device information, including information about the other wearable device, as the determination result.

The transmitting unit 370 transmits the on-site information notified by the on-site information acquiring unit 350 to the server device 140. The on-site information transmitted by the transmitting unit 370 to the server device 140 includes position information, audio information, image information, biometric information, and peripheral device information.

The transmission of on-site information by the transmission unit 370 may be started regardless of the occurrence of a disaster, or may be started when triggered by the occurrence of a disaster. When started when triggered by the occurrence of a disaster, the transmission unit 370 starts transmitting on-site information when triggered by the receipt of disaster information from the disaster information acquisition unit 310 or the receipt of disaster information from the receiving unit 340.

When the process is started regardless of the occurrence of a disaster, the transmission unit 370 may be configured to use the occurrence of a disaster as a trigger to shorten the interval at which on-site information is transmitted compared to before the disaster occurred.

Similarly, the on-site information acquisition unit 350 may be started regardless of the occurrence of a disaster, or may be started when triggered by the occurrence of a disaster. When started when triggered by the occurrence of a disaster, the on-site information acquisition unit 350 is started when disaster information is notified by the disaster information acquisition unit 310 or when disaster information is notified by the receiving unit 340.

When activated regardless of the occurrence of a disaster, the on-site information acquisition unit 350 may be configured to use the occurrence of a disaster as a trigger to shorten the interval for acquiring on-site information compared to before the occurrence of the disaster.

<Hardware configuration of server device>
Next, a hardware configuration of the server device 140 will be described. Fig. 4 is a diagram showing an example of the hardware configuration of the server device 140. As shown in Fig. 4, the server device 140 has a processor 401, a memory 402, an auxiliary storage device 403, a connection device 404, a communication device 405, and a drive device 406. The hardware components constituting the server device 140 are connected to each other via a bus 407.

The processor 401 has various computing devices such as a CPU (Central Processing Unit). The processor 401 reads various programs (such as the disaster information analysis program described above) onto the memory 402 and executes them.

The memory 402 has a primary storage device such as a ROM (Read Only Memory) or a RAM (Random Access Memory). The processor 401 and the memory 402 form a so-called computer (also called a "control unit"), and the processor 401 executes various programs read onto the memory 402, causing the computer to realize various functions.

The auxiliary storage device 403 stores various programs and various information (e.g., disaster response instructions, attribute information) used when the various programs are executed by the processor 401.

The connection device 404 is a connection device that connects an external device (e.g., a display device 410, an operation device 411) to the server device 140.

The communication device 405 is a communication device for transmitting and receiving various information (e.g., disaster information, on-site information, weather information, disaster response instructions, etc.) between the disaster monitoring device 110, the wearable devices 120_1 to 120_n, and the information providing system 130.

The drive unit 406 is a device for setting the recording medium 430. The recording medium 430 here includes media that record information optically, electrically, or magnetically, such as CD-ROMs, flexible disks, and magneto-optical disks. The recording medium 430 may also include semiconductor memory that records information electrically, such as ROMs and flash memories.

The various programs to be installed in the auxiliary storage device 403 are installed, for example, by setting the distributed recording medium 430 in the drive device 406 and reading the various programs recorded on the recording medium 430 by the drive device 406. Alternatively, the various programs to be installed in the auxiliary storage device 403 may be installed by downloading them from a network via the communication device 405.

<Functional configuration of the server device>
Next, a detailed description will be given of the functional configuration of the server device 140. As described above, the server device 140 functions as a receiving unit 141, an acquiring unit 142, a generating unit 143, and a transmitting unit 144. Here, the detailed functional configuration of the generating unit 143 will be described.

Figure 5 is a diagram showing an example of the functional configuration of the generation unit of the server device. As shown in Figure 5, the generation unit 143 has a disaster information acquisition unit 510, an instruction generation unit 520, a surrounding information analysis unit 530, a biometric information analysis unit 540, a position information analysis unit 550, a meteorological information analysis unit 560, and an instruction change unit 570.

When disaster information is notified from the acquisition unit 142, the disaster information acquisition unit 510 notifies the transmission unit 144 and the instruction generation unit 520.

When disaster information is notified from the disaster information acquisition unit 510, the instruction generation unit 520 refers to the disaster response information storage unit 145 to select disaster response instructions from the disaster information that correspond to the work process of the on-site work, and notifies the transmission unit 144 as initial response instructions. Note that when selecting disaster response instructions, the instruction generation unit 520 refers to the worker information storage unit 146 to select disaster response instructions that are suitable for the attribute information of each on-site worker.

When the surrounding information analysis unit 530 is notified of the site information from the acquisition unit 142, it analyzes the image information, audio information, and peripheral device information contained in the site information. As a result, the surrounding information analysis unit 530 grasps surrounding information that indicates the situation around each site worker wearing each of the wearable devices 120_1 to 120_n, and notifies the instruction change unit 570 of the grasped surrounding information.

When the site information is notified from the acquisition unit 142, the biometric information analysis unit 540 analyzes the biometric information included in the site information. In this way, the biometric information analysis unit 540 grasps the physical condition of each site worker wearing each of the wearable devices 120_1 to 120_n, and notifies the instruction change unit 570 of the grasped physical condition.

When the location information is notified from the acquisition unit 142, the location information analysis unit 550 analyzes the location information. As a result, the location information analysis unit 550 determines where on the evacuation route of the manufacturing site each of the site workers wearing the wearable devices 120_1 to 120_n is located, and notifies the instruction change unit 570 of the determined location.

When weather information is notified from the acquisition unit 142, the weather information analysis unit 560 analyzes the notified weather information, identifies elements that pose a risk on evacuation routes at the manufacturing site, and notifies the instruction change unit 570 of the identified risk elements.

The instruction change unit 570 grasps the situation at the manufacturing site based on the information (surrounding information, physical condition, location, risk factors) notified from the surrounding information analysis unit 530 to the weather information analysis unit 560, and determines whether or not the current disaster response instructions need to be changed. If the instruction change unit 570 determines that the situation at the manufacturing site has changed and that the current disaster response instructions need to be changed, it selects disaster response instructions according to the situation at the manufacturing site and notifies the transmission unit 144.

The manufacturing site status grasped by the instruction change unit 570 may include, for example,
- Where on the evacuation route each worker is currently located within the manufacturing site;
What is the surrounding environment like around each location?
・Are there any problems with the physical condition of each on-site worker?
・Are there any dangers to the evacuation routes of the workers at the manufacturing site?
The instruction change unit 570 takes these circumstances into consideration comprehensively to determine whether or not the current disaster response instructions need to be changed.

For example, the instruction change unit 570 determines that the current evacuation route is not safe based on the surrounding information notified by the surrounding information analysis unit 530, and that the disaster response instructions need to be changed. In this case, the instruction change unit 570 selects a disaster response instruction that includes an evacuation route different from the current evacuation route.

For example, the instruction change unit 570 determines that there is a field worker requesting rescue based on the surrounding information notified from the surrounding information analysis unit 530, and determines that it is necessary to change the disaster response instructions. In this case, the instruction change unit 570 selects, as the disaster response instructions for the specific field worker, a disaster response instruction that includes rescue activities for the field worker requesting rescue.

For example, the instruction change unit 570 determines that it is difficult to continue the current evacuation method for a specific on-site worker based on the physical condition notified by the bioinformation analysis unit 540, and determines that it is necessary to change the disaster response instructions. In this case, the instruction change unit 570 selects disaster response instructions for the specific on-site worker that include an evacuation method different from that for other on-site workers.

For example, the instruction change unit 570 determines that the current evacuation route is not appropriate based on risk factors notified by the weather information analysis unit 560, and that the disaster response instructions need to be changed. In this case, the instruction change unit 570 selects disaster response instructions that include an evacuation route different from the current evacuation route.

Examples of cases in which the current evacuation route is determined to be inappropriate based on the notified risk factors include a situation in which a disaster has caused a harmful gas leak, and the wind direction has changed so that the current evacuation route is downwind of the point where the harmful gas is leaking. Or, a situation in which a disaster has caused harmful liquid to leak outside a manufacturing building, and it has started to rain, creating the possibility that the harmful liquid will mix with the rainwater and flow into the current evacuation route.

Similar to the instruction generation unit 520, when selecting disaster response instructions, the instruction change unit 570 also refers to the worker information storage unit 146 and selects disaster response instructions suitable for the attribute information of each on-site worker.

<Disaster Action Support Processing Flow>
Next, a description will be given of the flow of disaster action support processing in the disaster action support system 100. Fig. 6 is a sequence diagram showing the flow of disaster action support processing in the disaster action support system.

As shown in FIG. 6, when the disaster monitoring device 110 detects a disaster in step S601, the disaster monitoring device 110 transmits disaster information to the server device 140 in step S602.

In step S603, the disaster information acquisition unit 510 of the server device 140 acquires the disaster information, and in step S604, the disaster information acquisition unit 510 of the server device 140 notifies the instruction generation unit 520 of the disaster information. In addition, in step S605, the disaster information acquisition unit 510 of the server device 140 transmits the disaster information to the receiving unit 340 of the wearable device 120_1 via the transmitting unit 144.

In step S606, the receiver 340 of the wearable device 120_1 receives the disaster information and notifies the transmitter 370.

In step S607, the transmission unit 370 starts transmitting on-site information in response to notification of the disaster information.

On the other hand, in step S608, the instruction generation unit 520 of the server device 140 selects a disaster response instruction according to the disaster information. In addition, in step S609, the instruction generation unit 520 of the server device 140 transmits the selected disaster response instruction as an initial response instruction to the receiving unit 340 of the wearable device 120_1 via the transmitting unit 144.

In step S610, when the receiver 340 of the wearable device 120_1 receives the initial response instruction, it notifies the notification unit 330.

In step S611, the notification unit 330 of the wearable device 120_1 notifies the on-site worker of the notified initial response instructions.

In step S612, the transmitter 370 of the wearable device 120_1 transmits the site information to the server device 140.

In step S613, the information providing system 130 transmits the weather information to the server device 140.

In step S614, the instruction change unit 570 of the server device 140 grasps the situation at the manufacturing site by analyzing the image information, audio information, peripheral device information, biometric information, and location information contained in the site information, as well as weather information. Then, when the instruction change unit 570 of the server device 140 determines that the current disaster response instructions need to be changed due to a change in the situation at the manufacturing site, it selects new disaster response instructions according to the situation at the manufacturing site.

In step S615, the instruction change unit 570 of the server device 140 transmits the newly selected disaster response instruction to the receiving unit 340 of the wearable device 120_1 via the transmitting unit 144.

In step S616, the receiver 340 of the wearable device 120_1 receives the disaster response instruction and notifies the notification unit 330.

In step S617, the notification unit 330 of the wearable device 120_1 notifies the on-site worker of the notified disaster response instructions.

<Disaster information collection and processing using wearable devices>
Next, a flow of disaster information collection processing by the wearable device 120_1 will be described below. Fig. 7 is a flowchart showing the flow of disaster information collection processing by the wearable device.

In step S701, the disaster information notification unit 320 or the receiving unit 340 determines whether or not disaster information has been acquired. If it is determined in step S701 that disaster information has not been acquired (NO in step S701), the unit waits until disaster information is acquired.

On the other hand, if it is determined in step S701 that disaster information has been acquired (YES in step S701) and the disaster information has been detected by the device itself, the process proceeds to step S702. Note that the case where disaster information has been detected by the device itself refers to the case where the disaster information notification unit 320 has determined that disaster information has been acquired.

In step S702, the disaster information notification unit 320 transmits the acquired disaster information to the server device 140, and then proceeds to step S703.

If it is determined in step S701 that disaster information has been acquired (YES in step S701) and disaster information has been received from server device 140, the process proceeds directly to step S703. If disaster information has been received from server device 140, that is, if receiver 340 has acquired disaster information.

In step S703, the transmitting unit 370 starts transmitting the on-site information. If the on-site information has already been transmitted at this point, the transmitting unit 370 shortens the transmission interval when transmitting the on-site information, for example.

In step S704, the notification unit 330 obtains disaster response instructions and notifies the on-site workers.

In step S705, the notification unit 330 determines whether a new disaster response instruction different from the disaster response instruction being notified has been acquired. If it is determined in step S705 that a new disaster response instruction different from the disaster response instruction being notified has been acquired (YES in step S705), the process proceeds to step S706.

In step S706, the notification unit 330 notifies the on-site worker of the acquired disaster response instructions and proceeds to step S707.

On the other hand, if it is determined in step S705 that no new disaster response instructions different from the disaster response instructions being reported have been acquired (NO in step S705), the process proceeds directly to step S707.

In step S707, the transmission unit 370 determines whether or not to end the disaster information collection process. If the field worker has not completed the action based on the disaster response instruction, in step S707, it is determined that the disaster information collection process is not to be ended (NO in step S707), and the process returns to step S705.

On the other hand, if the on-site worker has completed the actions based on the disaster response instructions, it is determined in step S707 that the disaster information collection process is to end (YES in step S707), and the process proceeds to step S708.

In step S708, the transmission unit 370 stops transmitting the on-site information and then ends the disaster information collection process. Alternatively, the transmission unit 370 lengthens the transmission interval for transmitting the on-site information and then ends the disaster information collection process.

<Disaster information analysis processing by server device>
Next, a description will be given of the flow of disaster information analysis processing by the server device 140. Fig. 8 is a flowchart showing the flow of disaster information analysis processing by the server device.

In step S801, the generation unit 143 determines whether or not disaster information has been acquired. If it is determined in step S801 that disaster information has not been acquired (NO in step S801), the generation unit 143 waits until disaster information is acquired.

On the other hand, if it is determined in step S801 that disaster information has been acquired (YES in step S801), the process proceeds to step S802.

In step S802, the transmission unit 144 transmits the disaster information to the wearable devices 120_1 to 120_n (excluding the wearable device that detected the disaster information).

In step S803, the generation unit 143 selects disaster response instructions corresponding to the work process of the on-site work from the disaster information, and the transmission unit 144 transmits the selected disaster response instructions to the wearable devices 120_1 to 120_n as initial response instructions.

In step S804, the receiving unit 141 starts receiving on-site information and weather information.

In step S805, the generation unit 143 grasps the situation at the manufacturing site based on the site information and weather information, and determines whether or not the current disaster response instructions need to be changed. In step S805, if it is determined that the situation at the manufacturing site has changed and that the current disaster response instructions need to be changed (YES in step S805), the process proceeds to step S806.

In step S806, the generation unit 143 selects a new disaster response instruction, and the transmission unit 144 transmits the selected new disaster response instruction to the wearable devices 120_1 to 120_n, and the process proceeds to step S807.

On the other hand, if it is determined in step S805 that the current disaster response instructions do not need to be changed (NO in step S805), the process proceeds directly to step S807.

In step S807, the receiving unit 141 determines whether or not to end the disaster information analysis process. Here, it is assumed that among the field workers wearing the wearable devices 120_1 to 120_n, there is a field worker who has not completed the action based on the disaster response instructions. In this case, the receiving unit 141 determines not to end the disaster information analysis process in step S807 (determines NO in step S807) and returns to step S805.

On the other hand, assume that all of the field workers wearing wearable devices 120_1 to 120_n have completed their actions based on the disaster response instructions. In this case, the receiver 141 determines in step S807 that the disaster information analysis process is to be ended (determines YES in step S807), and proceeds to step S808.

In step S808, the receiving unit 141 ends reception of on-site information and weather information.

<Summary>
As is clear from the above description, the disaster action support system 100 according to the first embodiment has the following features:
- When disaster information is acquired, disaster response instructions are selected based on the acquired disaster information and sent to the wearable device.
- By communicating with a wearable device worn by a field worker, disaster response instructions are selected based on field information (including at least surrounding information in addition to location information) obtained from the wearable device.

As a result, according to the first embodiment, it is possible to provide a disaster action support system and a disaster information analysis program that can provide disaster response instructions according to the situation at the manufacturing site after a disaster occurs.

In addition, the disaster action support devices (wearable devices) 120_1 to 120_n according to the first embodiment are
・Get disaster information.
- Obtain site information including at least the location information of the site worker and surrounding information.
After the disaster information is acquired, the on-site information is transmitted to the server device.

As a result, according to the first embodiment, it is possible to provide a disaster action support device and a disaster information collection program that can provide disaster response instructions according to the situation at the manufacturing site after a disaster occurs.

Second Embodiment
In the first embodiment, the voice information acquired by the wearable device is transmitted to the server device and analyzed by the server device. However, the method of using the voice information is not limited to this, and the voice information may be used, for example, for a call with a remote worker.

In the above first embodiment, the on-site information transmitted by the wearable device has been described as including audio information, image information, peripheral device information, biometric information, and location information. However, as long as the on-site information includes at least one or both of audio information and image information in addition to location information, it may or may not include other information.

In the above first embodiment, the on-site information analyzed by the server device has been described as including audio information, image information, peripheral device information, biometric information, and location information. However, it is sufficient that the on-site information analyzed by the server device includes at least either audio information or image information, or both, in addition to location information.

In the above first embodiment, the instruction change unit 570 was described as changing the initial response instruction to a new disaster response instruction by selecting a disaster response instruction appropriate to the situation at the manufacturing site from among multiple disaster response instructions stored in the disaster response information storage unit 145.

However, the method of changing the initial response instruction to a new disaster response instruction is not limited to this. For example, the instruction change unit 570 may be configured to change the initial response instruction to a new disaster response instruction by rewriting the initial response instruction to a disaster response instruction that corresponds to the situation at the manufacturing site. Alternatively, the instruction change unit 570 may be configured to change the initial response instruction to a new disaster response instruction by generating a new disaster response instruction that corresponds to the situation at the manufacturing site.

In other words, changing to new disaster response instructions includes selecting new disaster response instructions, rewriting the initial response instructions, or generating new disaster response instructions.

In the above first embodiment, the instruction generation unit 520 has been described as generating an initial response instruction by selecting a disaster response instruction corresponding to the work process of the on-site work from among multiple disaster response instructions stored in the disaster response information storage unit 145 based on the disaster information. However, the method of generating an initial response instruction is not limited to this. For example, the instruction generation unit 520 may be configured to generate an initial response instruction by rewriting a default disaster response instruction based on the disaster information. Alternatively, the instruction generation unit 520 may be configured to newly generate an initial response instruction corresponding to the disaster information.

In addition, in the above first embodiment, it is described that the disaster information collection program is started in advance, but it may be configured to start the disaster information collection program after receiving disaster information. In this case, however, the function of acquiring or receiving disaster information (i.e., the disaster information acquisition unit) is realized by a program different from the disaster information collection program.

In addition, in the first embodiment, a wearable device attached to a field worker is used, but instead of a wearable device, a mobile terminal carried by the field worker may be used.

Although the embodiments have been described above, it will be understood that various changes in form and details are possible without departing from the spirit and scope of the claims.
