  Hereinafter, embodiments of a system, an information processing method, an information processing apparatus, and a program according to the present invention will be described in detail with reference to the accompanying drawings.

(First embodiment)
FIG. 1 is a block diagram illustrating a configuration example of a system 1 according to the present embodiment. As shown in FIG. 1, the system 1 includes an evacuation information distribution server 10 and a projector 20. The evacuation information distribution server 10 and the projector 20 are connected to each other via the network 30. In this example, only one projector 20 is illustrated, but not limited to this, the number of projectors 20 connected to the evacuation information distribution server 10 is arbitrary. In this example, the evacuation information distribution server 10 corresponds to the “information processing device” in the claims, and the projector 20 corresponds to the “output device” in the claims, but is not limited thereto.

  As illustrated in FIG. 1, the evacuation information distribution server 10 includes a communication unit 11, a determination unit 12, and a generation unit 13. The communication unit 11 has a function of communicating with the projector 20. In this example, the communication unit 11 also has a function of communicating with an external device (not shown) that transmits disaster information described later.

  The determination unit 12 determines whether or not it is necessary to transmit (distribute) evacuation information for evacuating a person to the projector 20 when a disaster occurs. In the present embodiment, when a disaster occurs, an external device (not shown) transmits disaster information notifying that a disaster has occurred to the evacuation information distribution server 10. When the disaster information is received by the communication unit 11, the determination unit 12 determines that the evacuation information needs to be transmitted to the projector 20. For example, the evacuation information distribution server 10 has a function for detecting the occurrence of a disaster (for example, a function for detecting the occurrence of an earthquake or a function for detecting the occurrence of a fire). When detected, the determination unit 12 may be notified of this. Receiving this notification, the determination unit 12 can determine that the evacuation information needs to be transmitted to the projector 20. In other words, the determination unit 12 detects the occurrence of a disaster (may be detected by receiving disaster information from an external device, or may be detected by a function of the evacuation information distribution server 10). In this case, it is determined that the evacuation information needs to be transmitted to the projector 20.

  If the determination unit 12 determines that the evacuation information needs to be delivered to the projector 20, the determination unit 12 requests the communication unit 11 to transmit the simultaneous information notifying that the evacuation information needs to be transmitted to the projector 20. Upon receiving this request, the communication unit 11 transmits (distributes) the simultaneous information to the projector 20. That is, the communication unit 11 has a function of transmitting, to the projector 20, simultaneous information notifying that the evacuation information needs to be transmitted when the evacuation information needs to be transmitted to the projector 20. In this example, the communication unit 11 has a function of “first transmission unit” in the claims.

  The communication unit 11 receives the environment information of the projector 20 as a response to the simultaneous information. In this example, it can be understood that the communication unit 11 also has the function of the “first receiving unit” in the claims.

  Here, the function of the projector 20 regarding environmental information is demonstrated. As shown in FIG. 1, the projector 20 includes a communication unit 21, a collection unit 22, and a projection unit 23. The communication unit 21 communicates with the evacuation information distribution server 10. The communication unit 21 has a function of receiving the above-described simultaneous information. In this example, the communication unit 21 can be regarded as having the function of the “second receiving unit” in the claims.

  When the simultaneous information is received by the communication unit 21, the collection unit 22 collects environmental information of the projector 20. In this example, the environment information includes information indicating the installation location of the projector 20, information indicating the number of people around the current projector 20, information indicating the temperature around the current projector 20, and information about the current projector 20. It includes information indicating the ambient illuminance (brightness). FIG. 2 is a diagram illustrating an example of environment information.

  Here, a method for registering the installation location of the projector 20 will be described. As shown in FIG. 3, when the projector 20 is installed, the projector 20 transmits an installation notification indicating that the projector 20 is installed to the evacuation information distribution server 10. The evacuation information distribution server 10 holds an installation location list of buildings to be managed, and transmits the installation location list to the projector 20. The projector 20 that has received the installation location list projects the installation location list and prompts the user to register (select) the installation location of the projector 20. The installation location list in which the installation locations of the projector 20 are registered is stored in a memory (not shown) in the projector 20. The collection unit 22 accesses (not shown) the memory and collects (acquires) information indicating the installation location of the projector 20.

  In the present embodiment, as shown in FIG. 4, a camera 210 is connected to the ceiling-mounted projector 20 to photograph the vicinity of the installation location of the projector 20. The collection unit 22 collects (acquires) information indicating the number of people present around the current projector 20 by counting the number of people present around the projector 20 from the video captured by the camera 210. To do.

  Further, in the present embodiment, a temperature sensor 213 (see FIG. 13 described later) is connected to the projector 20. The collection unit 22 collects (acquires) the temperature measured by the temperature sensor 213 as information indicating the current temperature around the projector 20.

  When the collection of the environmental information as described above is completed, the collection unit 22 requests the communication unit 21 to transmit the collected environmental information to the evacuation information distribution server 10 as a response to the simultaneous information. Upon receiving this request, the communication unit 21 transmits the environment information collected by the collection unit 22 to the evacuation information distribution server 10. In this example, the communication unit 21 can also be regarded as having the function of the “third transmission unit” in the claims.

  Returning to FIG. 1, the description of the evacuation information distribution server 10 will be continued again. When the communication unit 11 receives environment information from the projector 20, the generation unit 13 generates evacuation information to be output to the projector 20 based on the received environment information. In this example, the communication unit 11 can be regarded as having the function of the “second receiving unit” in the claims.

  Hereinafter, a specific method for generating evacuation information will be described. In the present embodiment, the generation unit 13 associates the environment information received by the communication unit 11 with one or more evacuation routes and an allowable number of people that can be guided for each installation location of the projector. Based on the above, evacuation information to be output to the projector 20 is generated. More specifically, the generation unit 13 generates evacuation information by selecting an evacuation route so that the number of people existing around the current projector 20 indicated by the environment information received by the communication unit 11 falls within the allowable number of people. To do. FIG. 5 is a diagram illustrating an example of correspondence information. The correspondence information may be stored in a memory (not shown) or may be stored in an external device.

  Now, for example, assume that the communication unit 11 receives the environment information shown in FIG. As shown in FIG. 6, the installation location of the projector 20 indicated by the environmental information (the installation location of the projector 20 specified by information included in the environmental information (information indicating the installation location of the projector 20)) is “1F in front of the lobby”. In addition, since the number of people around the current projector 20 indicated by the environment information is “30”, the generation unit 13 selects the projector 1 that indicates “1F lobby before” from the evacuation routes included in the correspondence information. The evacuation route is selected so as to correspond to the installation location and the corresponding allowable number of people is within “30 people”. In this example, both the west exit and the south exit need to be selected. And the production | generation part 13 produces | generates the information which shows evacuating (evacuating outside) from both a west exit and a south exit as information which shows an evacuation route.

  Returning to FIG. 1, the description will be continued. In the present embodiment, the generation unit 13 generates evacuation information indicating that the urgency until evacuation is high when the temperature around the current projector 20 indicated by the environment information received by the communication unit 11 is equal to or higher than the first threshold. Generate. Furthermore, when the illuminance around the current projector 20 indicated by the environment information received by the communication unit 11 is less than the second threshold, the generation unit 13 generates evacuation information indicating that the urgency until evacuation is high. FIG. 7 is a diagram illustrating an example of determination index information used to determine the urgency until evacuation. In this example, the temperature threshold (first threshold) for determining whether the urgency to evacuation is high indicates 40 ° C., and the illuminance (brightness) for determining whether the urgency to evacuation is high. ) (Second threshold) is 10 lux (hereinafter expressed as “10 lx”), but is not limited thereto. The determination index information may be stored in a memory (not shown) or may be stored in an external device.

  Now, for example, assume that the communication unit 11 receives the environment information shown in FIG. As shown in FIG. 8, the current temperature around the projector 20 indicated by the environmental information is “24 ° C.”, which is lower than the first threshold value of 40 ° C. Further, as shown in FIG. 8, the illuminance (brightness) around the current projector 20 indicated by the environmental information is “200 lx”, which exceeds the second threshold value of 10 lx, so that the urgency until evacuation is low. To be judged. And the production | generation part 13 produces | generates the information which shows that the urgency to evacuation is low as information which shows the urgency to evacuation.

  The generation unit 13 determines evacuation information from the information indicating the evacuation route generated as described above and the information indicating the degree of urgency until evacuation. For example, if the urgency until evacuation is low, combine information indicating the evacuation route and information (message) indicating that there is a grace period until evacuation starts, such as “Start evacuation after 10 minutes” It can also be used as evacuation information. For example, when the degree of urgency before evacuation is low, information that prompts the user to start evacuation may not be included in the evacuation information. Furthermore, for example, when the urgency to evacuation is high, evacuation information should be combined with information indicating the evacuation route and information prompting to start evacuation immediately, such as “Please start evacuation immediately” You can also.

  FIG. 9 is a flowchart illustrating an example of processing performed by the generation unit 13. As described above, the generation unit 13 determines the urgency level until evacuation from the above-described determination index information and the current temperature or brightness around the projector 20 indicated by the environment information received from the projector 20 (step S1). ). Further, the generation unit 13 selects an evacuation route from the correspondence information described above, the installation location of the projector 20 indicated by the environment information received from the projector 20 and the number of people around the current projector 20 (step S2). Note that the order of step S1 and step S2 may be reversed or simultaneous. Next, the generation unit 13 determines evacuation information from the urgency level until evacuation determined in step S1 and the evacuation route determined in step S2 (step S3).

  Returning to FIG. 1, the description will be continued. The generation unit 13 requests the communication unit 11 to transmit the evacuation information generated as described above to the projector 20. Upon receiving this request, the communication unit 11 transmits evacuation information to the projector 20. In this example, the communication unit 11 can also be regarded as having the function of the “second transmission unit” in the claims.

  Then, the communication unit 21 on the projector 20 side receives the evacuation information from the evacuation information distribution server 10. In this example, the communication unit 21 can also be regarded as having the function of the “third receiving unit” in the claims. The projection unit 23 projects the evacuation information received by the communication unit 21 onto a projection surface such as a screen. FIG. 10 is a diagram illustrating an example of evacuation information projected on the projection plane. In this example, the projection unit 23 can be regarded as corresponding to the “output unit” in the claims.

  FIG. 11 is a sequence diagram illustrating an example of an operation procedure of the system 1 according to the present embodiment. As shown in FIG. 11, when a disaster such as an earthquake or a fire occurs, the communication unit 11 receives disaster information from an external device (not shown) (step S10). The communication unit 11 notifies the determination unit 12 of the received disaster information (step S11). Receiving this notification, the determination unit 12 determines that transmission (distribution) of the simultaneous information is necessary, and requests the projector 20 to transmit the simultaneous information (step S12). Upon receiving this request, the communication unit 11 transmits simultaneous information to the projector 20 (step S13).

  When the communication unit 21 on the projector 20 side receives the simultaneous information from the evacuation information distribution server 10, the communication unit 21 notifies the collection unit 22 that the simultaneous information has been received (step S14). Upon receiving this notification, the collection unit 22 collects environmental information of the projector 20 (step S15). When the collection of the environmental information is completed, the collection unit 22 requests the communication unit 21 to transmit the environmental information to the evacuation information distribution server 10 (step S16). Upon receiving this request, the communication unit 21 transmits environmental information to the evacuation information distribution server 10 (step S17).

  When the communication unit 11 on the evacuation information distribution server 10 side receives the environment information from the projector 20, the communication unit 11 notifies the generation unit 13 of the received environment information (step S18). Upon receiving this notification, the generation unit 13 generates evacuation information to be output to the projector 20 based on the environment information (step S19). The method for generating evacuation information is as described above. Then, the generation unit 13 requests the communication unit 11 to transmit the generated evacuation information to the projector 20 (step S20). Upon receiving this request, the communication unit 11 transmits evacuation information to the projector 20 (step S21).

  When receiving the evacuation information from the evacuation information distribution server 10, the communication unit 21 on the projector 20 side notifies the projection unit 23 of the received evacuation information (step S22). Receiving this notification, the projection unit 23 projects the evacuation information transmitted from the evacuation information distribution server 10 (step S23).

  Next, the hardware configuration of the evacuation information distribution server 10 will be described. FIG. 12 is a diagram illustrating a hardware configuration example of the evacuation information distribution server 10. As shown in FIG. 12, the evacuation information distribution server 10 includes a CPU 101, a ROM 102, a RAM 103, an input unit 104, a display unit 105, and a communication I / F 106, which are mutually connected via a system bus 107. It is connected to the.

The CPU 101 controls the overall operation of the evacuation information distribution server 10 by executing a program stored in the ROM 102 or an external storage device (not shown) (for example, a hard disk drive) using the RAM 103 as a work area (work area).

  The input unit 104 is a device used for various inputs, and may be configured with, for example, a keyboard or a mouse. The display unit 105 is a device that displays various information related to the evacuation information distribution server 10 and the system 1, and may be configured by, for example, a liquid crystal display device. In addition, for example, a display device in which a touch panel function is mounted without providing the input unit 104 may be configured to share the functions of the input unit 104 and the display unit 105.

  The communication I / F 106 is an interface for communicating with the projector 20 and an external device via the network 30 such as the Internet.

  The functions (communication unit 11, determination unit 12, and generation unit 13) of each unit of the evacuation information distribution server 10 described above are realized by the CPU 101 executing a program stored in the ROM 102 or the like. For example, at least a part of the functions (communication unit 11, determination unit 12, and generation unit 13) of each unit of the evacuation information distribution server 10 described above is realized by a dedicated hardware circuit (for example, a semiconductor integrated circuit). Also good.

  Next, the hardware configuration of the projector 20 will be described. FIG. 13 is a diagram illustrating a hardware configuration example of the projector 20. As shown in FIG. 13, the projector 20 has a CPU 201 that controls the overall operation of the projector 20. In the example of FIG. 13, the projector 20 has an ASIC 202. The ASIC 202 is an IC for image processing applications having hardware elements for image processing, and includes a CPU 201, Ethernet (registered trademark) 203, Wi-Fi 204, an image creation engine 205, HDMI (registered trademark) 208, VIDEO-IN 209, It has a role of a bridge for connecting the DSP 212 and the flash memory 214 respectively.

Further, the projector 20 includes an image forming engine 205, a light source 206, and a lens 207 for projecting the above-described evacuation information.

  In the example of FIG. 13, the projector 20 includes an HDMI (registered trademark) 208 to which an external video is input, and a VIDEO-IN 209. Further, a camera 210 used for collecting the number of people present around the projector 20 is connected to the CPU 201 via the USB 211. Using the image photographed by the camera 210, the CPU 201 and the DSP 212 perform image segmentation and person detection, thereby collecting the number of people present around the projector 20. In the example of FIG. 13, a temperature sensor 213 that measures the temperature around the projector 20 is connected to the CPU 201.

  In the example of FIG. 13, the projector 20 includes a flash memory 214 that stores various data and programs. In this example, the functions (communication unit 21, collection unit 22, projection unit 23) of each unit of the projector 20 described above are realized by the CPU 201 executing a program stored in the flash memory 214 or the like. For example, at least a part of the functions (communication unit 21, collection unit 22, projection unit 23) of each unit of the projector 20 described above may be realized by a dedicated hardware circuit.

  As described above, in the present embodiment, when a disaster such as an earthquake or a fire occurs, optimal evacuation information corresponding to the environmental information of the projector 20 at that time is generated and distributed to the projector 20. There is an advantageous effect that it is possible to present optimal evacuation information according to a real-time situation at a place where the projector 20 is installed to a person existing around the projector 20.

(Second Embodiment)
Next, a second embodiment will be described. In the second embodiment, the evacuation information distribution server 10 is connected to two or more projectors via the network 30. Here, for convenience of explanation, the evacuation information distribution server 10 will be described as an example in which it is connected to two projectors (20A, 20B) via the network 30. When there is no need to distinguish between the two projectors, they are simply referred to as the projector 20. In the following description, description of parts common to the above-described first embodiment will be omitted as appropriate.

  In this embodiment, the evacuation information distribution server 10 receives the disaster information from an external device (not shown) (when it is determined that the evacuation information needs to be distributed to the projectors 20A and 20B), the projector 20A and Simultaneous information is distributed to each of 20B. Then, when the generation unit 13 receives environmental information from each of the projectors 20A and 20B as a response to the simultaneous information, the generation unit 13 causes each projector 20 to output the projector 20 based on the environmental information of the projector 20 Generate information. More specifically, the generation unit 13 indicates the environment information of the projector 20 for each projector 20 based on the environment information of each of the projectors 20A and 20B received by the communication unit 11 and the correspondence information described above. Evacuation information is generated by selecting an evacuation route so that the number of people around the projector 20 is within the allowable number.

  Assume that the environment information of the projector 20A and the environment information of the projector 20B shown in FIG. As shown in FIG. 14, the installation location of the projector 20A indicated by the environment information of the projector 20A is “1F A section”, and the number of people around the current projector 20A indicated by the environment information of the projector 20A is “20 people”. Therefore, both the west exit and the north exit can be selected as the evacuation route corresponding to the projector 20A.

  On the other hand, the installation location of the projector 20B indicated by the environment information of the projector 20B is “2FC section”, and the number of people around the current projector 20B indicated by the environment information of the projector 20B is “20 people”. As an evacuation route corresponding to 20B, only an evacuation route that goes to the north exit through the north stairs can be selected. Here, the generation unit 13 selects the west exit as the evacuation route corresponding to the projector 20A and the north side as the evacuation route corresponding to the projector 20B so that the evacuation route corresponding to the projector 20A and the evacuation route of the projector 20B do not overlap. Choose an exit. Then, the generation unit 13 generates information indicating evacuation from the west exit as information indicating the evacuation route corresponding to the projector 20A, and evacuates from the north exit as information indicating the evacuation route corresponding to the projector 20B. The information which shows that is produced | generated.

  FIG. 15 is a flowchart illustrating an example of processing performed by the evacuation information distribution server 10 from when environmental information of each projector 20 is received until evacuation information is distributed to each projector 20. As shown in FIG. 15, first, the communication unit 11 receives environment information from each of the projectors 20A and 20B as a response to the simultaneous information (step S31). Next, the generation unit 13 has only one evacuation route corresponding to the installation location of the projector 20 indicated by the environment information in the projectors 20A and 20B from the environment information of each projector 20 and the above-described correspondence information. It is determined whether or not there is a projector (step S32). In the example of FIG. 14, the correspondence information indicates that the evacuation route associated with the installation location “2FC section” of the projector 20 indicated by the environment information of the projector 20 </ b> B “goes to the north exit through the north stairs”. Since only the evacuation route is used, the determination result in step S32 is affirmative.

  When it is determined in step S32 described above that there is a projector having only one evacuation route corresponding to the installation location of the projector 20 indicated by the environment information (step S32: YES), the generation unit 13 sets the environment information of the projector 20 The evacuation route corresponding to the installation location indicated by is selected (step S33). On the other hand, when it is determined in step S32 described above that there is no projector having only one evacuation route corresponding to the installation location of the projector 20 indicated by the environment information (step S32: NO), the generation unit 13 selects the evacuation route. The evacuation route is selected so that the number of people around the projector 20 (the number of people in the vicinity) indicated by the environmental information of the target projector 20 (one of the projectors 20A and 20B) to be selected falls within the allowable number. (Step S34).

  Next, the generation unit 13 subtracts the number of people in the vicinity indicated by the environmental information of the target projector 20 from the allowable number of people corresponding to the selected evacuation route (step S35). Then, the target projector 20 determines that the evacuation route has been selected (step S36), and determines whether the evacuation routes of all the projectors 20 have been selected (step S37).

  If it is determined in step S37 described above that there is a projector 20 that has not yet selected an evacuation route (step S37: NO), the processes in step S32 and subsequent steps are repeated. On the other hand, when determining that the evacuation routes of all the projectors 20 have been selected (step S37: YES), the generation unit 13 generates evacuation information for each projector 20 (step S38). At this time, similarly to the first embodiment described above, the generation unit 13 generates an emergency for each projector 20 based on the above-described determination index information and the temperature or brightness around the projector 20 indicated by the environmental information of each projector 20. Information indicating the degree may be generated. And the production | generation part 13 may produce | generate evacuation information for every projector 20 from the information which shows an evacuation route, and the information which shows an emergency. Next, the generation unit 13 requests the communication unit 11 to distribute the evacuation information corresponding to the projector for each projector 20, and the communication unit 11 that has received this request transmits the projector 20 for each projector 20. The evacuation information corresponding to is transmitted (step S39). The above is the contents of the processing by the evacuation information distribution server 10 from the reception of the environment information of each projector 20 to the distribution of the evacuation information to each projector 20.

  Here, for example, the generation unit 13 includes, in the environmental information of each projector 20 received by the communication unit 11, environmental information indicating that the temperature around the projector 20 is equal to or higher than the third threshold value. The form which does not select the evacuation route close | similar to the installation place of the projector 20 which the said environment information shows may be sufficient.

  For example, assume that the communication unit 11 receives the environment information of the projector 20A and the environment information of the projector 20B shown in FIG. In this example, the third threshold value used to determine whether or not the evacuation route can be selected is set to “40 ° C.”, but is not limited thereto. As shown in FIG. 16, the ambient temperature of the projector 20B indicated by the environmental information of the projector 20B is “50 ° C.” and exceeds the third threshold value of 40 ° C. Therefore, the generation unit 13 indicates that the environmental information of the projector 20B is The “west exit” that is an evacuation route close to the installation location “1F in front of the west exit” of the projector 20B shown is not selected.

  Then, in the example of FIG. 16, the installation location of the projector 20A indicated by the environment information of the projector 20A is “1F A section”, and the number of people around the current projector 20A indicated by the environment information of the projector 20A is “20 people”. Therefore, among the evacuation routes included in the correspondence information, as the evacuation route corresponding to the installation location of the projector indicating “1F A section” and the corresponding allowable number of people within “20 people”, However, since the west exit cannot be selected as described above, the generation unit 13 selects the north exit as an evacuation route corresponding to the projector 20A.

  In the example of FIG. 16, the installation location of the projector 20B indicated by the environment information of the projector 20B is “1F in front of the west exit”, and the number of people around the current projector 20B indicated by the environment information of the projector 20B is “10”. As the evacuation route corresponding to the installation location of the projector indicating “1F West Exit” and the corresponding allowable number of people within “10 people” among the evacuation routes included in the correspondence information, Although the west side exit and the south side exit are candidates, since the west side exit cannot be selected as described above, the generation unit 13 selects the south side exit as the evacuation route corresponding to the projector 20B. As described above, the generation unit 13 generates information indicating evacuation from the north exit as information indicating the evacuation route corresponding to the projector 20A, and evacuates from the south exit as information indicating the evacuation route corresponding to the projector 20B. Generate information that indicates what to do.

  FIG. 17 is a flowchart showing an example of processing by the evacuation information distribution server 10 from the reception of the environment information of each projector 20 to the distribution of evacuation information to each projector 20 in the above embodiment. As shown in FIG. 17, first, the communication unit 11 receives environmental information from each of the projectors 20A and 20B as a response to the simultaneous information (step S41). Next, the generation unit 13 determines whether the environmental information indicating that the ambient temperature of the projector 20 is equal to or higher than a third threshold (for example, 40 ° C.) is included in the environmental information of each projector 20. (Step S42).

  In step S42 described above, when it is determined that the environmental information of each projector 20 includes environmental information indicating that the temperature around the projector 20 is equal to or higher than the third threshold (step S42: YES). The generation unit 13 cannot select an evacuation route close to the installation location of the projector 20 indicated by the environment information (step S43), and the process proceeds to step S44. On the other hand, when it is determined that the environmental information indicating that the temperature around the projector 20 is equal to or higher than the third threshold is not included in the environmental information of each projector 20 (step S42: NO), the processing is performed as it is. The process proceeds to step S44.

  In step S44, the generation unit 13 determines whether there is a projector 20 having only one evacuation route corresponding to the installation location of the projector 20 indicated by the environment information (step S44). When it is determined that there is a projector having only one evacuation route corresponding to the installation location of the projector 20 indicated by the environmental information (step S44: YES), the generation unit 13 corresponds to the installation location indicated by the environmental information of the projector 20 The evacuation route to be selected is selected (step S45). In this case, for example, even if the allowable number of evacuation routes corresponding to the installation location indicated by the environment information of the projector 20 is smaller than the number of surrounding people indicated by the environment information, the generation unit 13 forces the evacuation route. To choose.

  On the other hand, when it is determined in step S44 described above that there is no projector having only one evacuation route corresponding to the installation location of the projector 20 indicated by the environment information (step S44: NO), the generation unit 13 selects the evacuation route. Of the selectable evacuation routes corresponding to the installation location indicated by the environmental information of the target projector 20 (one of the projectors 20A and 20B) to be selected, the evacuation in which the number of people in the vicinity indicated by the environmental information falls within the allowable number It is determined whether there is a route (step S46). If it is determined that there is an evacuation route that can be accommodated by the allowable number of people (step S46: YES), the generation unit 13 selects the evacuation route (step S47). On the other hand, when determining that there is no evacuation route that can be accommodated by the allowable number of people (step S46: NO), the generation unit 13 forcibly selects one of the selectable evacuation routes (step S48).

  Next, the generation unit 13 subtracts the number of people in the vicinity indicated by the environment information of the target projector 20 from the allowable number of people corresponding to the selected evacuation information (step S49). Then, the target projector 20 determines that the evacuation route has been selected (step S50), and determines whether the evacuation routes of all the projectors 20 have been selected (step S51).

  If it is determined in step S51 described above that there is a projector 20 that has not yet selected an evacuation route (step S51: NO), the processes in step S44 and subsequent steps are repeated. On the other hand, when it is determined that the evacuation routes of all the projectors 20 have been selected (step S51: YES), the generation unit 13 generates evacuation information for each projector 20 (step S52). At this time, similarly to the first embodiment described above, the generation unit 13 generates an emergency for each projector 20 based on the above-described determination index information and the temperature or brightness around the projector 20 indicated by the environmental information of each projector 20. Information indicating the degree may be generated. And the production | generation part 13 may produce | generate evacuation information for every projector 20 from the information which shows an evacuation route, and the information which shows an emergency.

  Next, the generation unit 13 requests the communication unit 11 to distribute the evacuation information corresponding to the projector for each projector 20, and the communication unit 11 that has received this request transmits the projector 20 for each projector 20. The evacuation information corresponding to is transmitted (step S53).

  FIG. 18 is a sequence diagram illustrating an example of an operation procedure of the system according to the present embodiment. As shown in FIG. 18, when a disaster such as an earthquake or a fire occurs, the communication unit 11 receives disaster information from an external device (not shown) (step S101). The communication unit 11 notifies the determination unit 12 of the received disaster information (step S102). Receiving this notification, the determination unit 12 determines that it is necessary to distribute the simultaneous information, and requests transmission of the simultaneous information to the projectors 20A and 20B (step S103). Upon receiving this request, the communication unit 11 transmits simultaneous information to each of the projector 20A and the projector 20B (step S104).

  When the projector 20A receives the simultaneous information from the evacuation information distribution server 10, the projector 20A collects environmental information of the projector 20A (step S105). Further, when the projector 20B receives the simultaneous information from the evacuation information distribution server 10, the projector 20B collects environmental information of the projector 20B (step S106). When the collection of the environmental information is completed, the projector 20A transmits the collected environmental information to the evacuation information distribution server 10 (step S107). Similarly, when the collection of the environmental information is completed, the projector 20B transmits the collected environmental information to the evacuation information distribution server 10 (step S108).

  When receiving the environment information from each of the projectors 20A and 20B, the communication unit 11 on the side of the evacuation information distribution server 10 notifies the generation unit 13 of the received environment information of each of the projectors 20A and 20B (step S109). Upon receiving this notification, the generation unit 13 generates evacuation information to be output to the projector 20 for each projector 20 based on the environmental information of each projector 20 (step S110). The method for generating evacuation information is as described above. Then, the generation unit 13 requests the communication unit 11 to distribute (transmit) the generated evacuation information for each projector 20 (step S111). Upon receiving this request, the communication unit 11 transmits the evacuation information for the projector 20A to the projector 20A (step S112), and transmits the evacuation information for the projector 20B to the projector 20B (step S113).

  When the projector 20A receives the evacuation information for the projector 20A from the evacuation information distribution server 10, the projector 20A projects the received evacuation information (step S114). When the projector 20B receives the evacuation information for the projector 20B from the evacuation information distribution server 10, the projector 20B projects the received evacuation information (step S115).

(Third embodiment)
Next, a third embodiment will be described. In the third embodiment, the collection unit 22 on the projector 20 side collects environmental information at regular intervals, and performs control to transmit the latest environmental information to the server device when the environmental information changes. And the production | generation part 13 by the side of the evacuation information delivery server 10 is different from each above-mentioned embodiment by the point which regenerates evacuation information based on the newest environmental information. This will be specifically described below. Note that description of portions common to the above-described embodiments is omitted as appropriate.

  FIG. 19 is a flowchart illustrating an example of processing performed by the collection unit 22 according to the third embodiment. As shown in FIG. 19, when simultaneous information from the evacuation information distribution server 10 is received by the communication unit 21 (step S61), the collection unit 22 collects environmental information of the projector 20 (step S62). When the collection of the environmental information is completed, the collection unit 22 requests the communication unit 21 to transmit the collected environmental information to the evacuation information distribution server 10. Receiving this request, the communication unit 21 transmits the environmental information to the evacuation information distribution server 10 (step S63).

  After a predetermined time has elapsed from step S63 described above, the collection unit 22 again collects environment information of the projector 20 (step S64). Then, the collection unit 22 determines whether or not there is a difference between the environmental information acquired last time and the environmental information acquired this time (step S65). When it is determined in step S65 that there is a difference (step S65: YES), the process proceeds to step S63 described above, and the environment information (latest environment information) acquired in step S64 is the evacuation information distribution server 10. Sent to. On the other hand, when it is determined in step S65 that there is no difference (step S65: NO), the processing after step S64 described above is repeated.

  Now, for example, as shown in FIG. 20 (a), it is assumed that the evacuation information distribution server 10 receives the environmental information of the projector 20 as of 13:00. In this example, the installation location indicated by the environmental information of the projector 20 as of 13:00 is “1F in front of the lobby” and the number of surroundings indicated by the environmental information is “10”. The evacuation route is selected so as to correspond to the installation location of the projector indicating “1F in front of the lobby” and the corresponding allowable number is within “10 people”. In this example, the generation unit 13 can select both the west side exit and the south side exit. And the production | generation part 13 can produce | generate the information which shows evacuating from one exit (this example south exit) in a west exit and a south exit as information which shows an evacuation route.

  Thereafter, as shown in FIG. 20B, for example, it is assumed that the evacuation information distribution server 10 receives the environmental information of the projector 20 as of 13:30. In this example, the installation location indicated by the environmental information of the projector 20 at 13:30 remains “1F in front of the lobby”, but the number of surrounding people indicated by the environmental information changes from “10” at 13:00 to “ Since it has changed to “30 people”, the generation unit 13 corresponds to the installation location of the projector indicating “1F in front of the lobby” from among the evacuation routes included in the correspondence information, and the corresponding allowable number is “30”. Select an evacuation route so that it fits in "people". In this example, the generation unit 13 selects both the west exit and the south exit. And the production | generation part 13 produces | generates the information which shows evacuating from both a west exit and a south exit as information which shows an evacuation route. As described above, according to the present embodiment, it is possible to present evacuation information according to the latest environmental information.
