The information corresponding to the item "fire occurrence location information" is fire occurrence location information indicating a sign of a fire or a location where a fire occurs. Arbitrary information can be used as the fire occurrence location information, and for example, information for specifying the section where the detector 2 is installed can be used, but in the present embodiment, the installation location of FIG. 5 can be used. The case where the information corresponding to the information is used will be described. In FIG. 8, a “restaurant” indicating a restaurant provided in the building of FIG. 1, a “lobby” indicating a lobby, a “parking lot” indicating a hotel parking lot provided around the building, and FIG. 2 The "room on the second floor" and the like showing the guest rooms on the second floor of the building (that is, rooms 1 to 5 on the second floor, etc.) are shown in the figure. The information corresponding to the item "group ID" is a group ID that uniquely identifies the chat group to which the user to be notified of the fire information belongs (in FIG. 8, the above-mentioned "IDg001" and the like).

As for the information at the top of the notification destination group specific information (information of a combination of "restaurant, lobby" and "IDg001, IDg002, IDg004"), the sign of fire or the place where the fire occurred is "restaurant". In the case of "lobby" or "lobby", it is shown that the group IDs that uniquely identify the chat group to which the user to be notified of the fire information belongs are "IDg001", "IDg002", and "IDg004". ing.

In the notification destination group identification information of FIG. 8, the fire occurrence location information (that is, the information for specifying the section where the sensor 2 is installed) and the group ID are mutually related, and are described above. In the chat group specific information of FIG. 7, the group ID and the terminal ID are mutually associated with each other. Therefore, in the notification destination group specific information of FIG. 8 and the chat group specific information of FIG. 7, the fire occurrence location information and the terminal Since the IDs are associated with each other, the notification destination group specific information in FIG. 8 and the chat group specific information in FIG. 7 are "a place indicating a place related to the target facility and a mobile terminal associated with the place". It may be interpreted as corresponding to "1 information".

(Configuration-Information sharing server-Recording unit-Chat history information)
The "chat history information" is information that identifies the history of information shared within each chat group in a group chat. FIG. 9 is a diagram illustrating chat history information. In this chat history information, for example, as shown in FIG. 9, the information corresponding to the item "group ID", the information corresponding to the item "group name information", and the information corresponding to the item "chat information" are mutual. Associated with. The information corresponding to the item "group ID" and the information corresponding to the item "group name information" are the same as the information having the same name in FIG. 7.

The information corresponding to the item "chat information" is information indicating the history of information shared with users belonging to the chat group. This chat information is arbitrary, but the case where, for example, information indicating the date and time when the information was shared, information for identifying the sharing subject of the information, and information in which the shared information is associated with each other is used will be described. do. In FIG. 9, “07011400” indicating 14:00 on July 01, which is the date and time when the information was shared, and “A1” in FIG. 1, which is the main body of information sharing, are the terminal devices 101 carried by the user. The terminal ID "IDt001" and the shared information "GG arrived, is the cleaning completed on the second floor?" Are interrelated with "07011400-IDt001-GG arrived. Is cleaning completed on the 2nd floor? " In addition, "GG" here is a description for convenience, and it is assumed that it is the name of the customer who visited the hotel. Further, the chat information is automatically stored in each process described later by the control unit 53 of the information sharing server 5 (not the input of information from each user side) and the case where each user inputs the information to store the chat information. However, in the case of the former (that is, chat information is stored by each user inputting information), "information for identifying the information sharing entity" is stored. In the case), the terminal ID is used as described above, and in the latter case (that is, when it is dynamically stored), "N" is used.

Then, the top-level information ("IDg005", "guest room group (2F)", and "07011400-IDt001-GG" associated with the "group ID" = "IDg005" of such chat history information have arrived. Regarding the information on the combination of "Is cleaning completed on the 2nd floor?"), It is shown that the name of the chat group identified by "IDg005" is "Room group (2F)", and the relevant "Room group (2F)". In the group chat of the chat group of "Room Group (2F)", it is shown that the information was input at 14:00 on July 01 indicated by "07011400", and the terminal device 1 of the user who input the information. The terminal ID of is shown to be "IDt001" (that is, it is shown that "A1", the user carrying the terminal device 105 indicated by "IDt001", has entered the information). , It is shown that the entered information is "G-sama arrived, is the second floor cleaned?".

Although the specific storage method of such chat history information is arbitrary, for example, it is assumed that the information of the same name in FIG. 7 is stored for the group ID and the group name information, and the chat information is described. , The sign-related processing, the fire-related processing, the fire level determination-related processing, and the chat processing, which will be described later, are to be stored.

(Configuration-Information sharing server-Control unit)
The control unit 53 in FIG. 3 is a control means for controlling the information sharing server 5. The processing performed by the control unit 53 will be described later.

(process)
Next, the chat process, the sign-related process, the fire-related process, and the fire level determination-related process executed by the disaster prevention system 100 configured as described above will be described.

In the recording unit 14 (FIG. 3) of the terminal devices 101 to 107 of FIG. 1, a group ID for identifying the chat group to which each user carrying the terminal devices 101 to 107 belongs is stored as a group ID by an arbitrary method. Explain that it is. As a method of storing this group ID, for example, at the time of initial setting of the terminal device 1, the control unit 53 of the information sharing server 5 is associated with each terminal ID with reference to the chat group specific information of FIG. The group ID may be specified and the specified group ID may be transmitted to each terminal device 1, and the control unit 15 of each terminal device 1 may store the group ID based on the transmitted group ID. Information may be stored by inputting information via the touch pad 12. Here, it is assumed that the group ID illustrated in FIG. 4 is stored in the recording unit 14 of each terminal device 1.

(Processing-Chat processing)
First, the chat process will be described. The "chat process" is a process for performing a group chat within a chat group, and specifically, is a process for sharing information within a chat group. As this chat process, a known processing technique for performing a group chat can be applied, so only an outline will be described. The "chat process" includes, for example, a chat information storage process and a chat information display process.

(Processing-Chat processing-Chat information storage processing)
The "chat information storage process" is a process for storing the chat information of FIG. 9 based on the information input from each user to the terminal device 1.

First, the user selects one chat group identified by the group ID stored in the recording unit 14 of the terminal device 1 as a chat group for sharing information by a predetermined operation performed via the touch pad 12. When the information to be shared in the selected chat group is input by an arbitrary method, the control unit 15 of the terminal device 1 acquires the terminal ID stored in its own recording unit 14. In addition, after acquiring the group ID that identifies the selected chat group described above and the input information described above, the acquired terminal ID, the group ID, and the information including the input information (hereinafter referred to as). , "Terminal-side storage information") is transmitted to the information sharing server 5. The method of inputting information to be shared within the chat group is arbitrary, and for example, text information may be input via the touch pad 12, or a sound collecting means such as a microphone may be used for the terminal device 1. However, in the present embodiment, a case where text information is input will be described.

Here, for example, "A1", who is in charge of the front desk in FIG. 1, is stored in the recording unit 14 of the terminal device 101 as a chat group for sharing information by a predetermined operation performed via the touch pad 12 of the terminal device 101. Select the chat group of the "guest room group (2F)" identified by "IDg005" in the "group ID" = "IDg001, IDg002, IDg003, IDg004, IDg005, IDg006, IDg007, ..." Control of terminal device 1 when "GG arrived, is cleaning completed on the 2nd floor?" Is input via the touch pad 12 as information to be shared within the selected "guest room group (2F)". The unit 15 acquires the "terminal ID" = "IDt001" stored in its own recording unit 14, and also acquires the "group ID" = "IDg005" that identifies the selected chat group described above. In addition, after acquiring the above-mentioned "input information" = "GG arrived, is the cleaning completed on the second floor?", Information on "terminal storage information" including these acquired information Send to the shared server 5.

On the other hand, the control unit 53 of the information sharing server 5 receives the "terminal-side storage information" transmitted from the terminal device 1, and an arbitrary method (for example, a time measuring means such as a timer provided in the information sharing server 5). After specifying the current date and time by the method of specifying by referring to the timing result of Stores chat information in. Specifically, in the chat history information of FIG. 9, the above-mentioned specified current date and time is used as the chat information associated with the same group ID as the group ID included in the above-mentioned received "terminal-side storage information". Information indicating, the "terminal ID" included in the above-mentioned received "terminal-side storage information", and the "input information" included in the above-mentioned received "terminal-side storage information" are mutually exchanged. The information associated with is stored as chat information.

Here, for example, when 14:00 on July 01 is specified as the current date and time, the "group ID" = "group ID" included in the received "terminal-side storage information" in the chat history information of FIG. As chat information associated with the same group ID as "IDg005", "07011400" indicating 14:00 on July 01, which is the specified current date and time, and "terminal-side storage information" received above. "Terminal ID" = "IDt001" included, and "Entered information" included in "Terminal side storage information" = "GG arrived, is the second floor cleaned?" "07011400-IDt001-GG has arrived, is the cleaning completed on the 2nd floor?" Store as chat information. This ends the "chat information storage process".

(Processing-Chat processing-Chat information display processing)
The "chat information display process" is a process for displaying the information corresponding to the chat information of the chat history information of FIG. 9 on the terminal device 1.

FIG. 10 is a diagram illustrating a group chat display screen. The "group chat display screen" is a screen for displaying information shared within each chat group in a group chat, for example, a screen displayed on the display 13 of the terminal device 1, and as an example, a group name. It has a display field 61 and a text display field 62. The group name display field 61 is a field for displaying the name of the chat group, and the text display field 62 is a field for displaying information shared within the chat group.

First, when the user selects one chat group identified by the group ID stored in the recording unit 14 of the terminal device 1 as a chat group for displaying information by a predetermined operation performed via the touch pad 12. The control unit 15 of the terminal device 1 acquires the terminal ID stored in its own recording unit 14, and also acquires the group ID that identifies the selected chat group described above, and then acquires the terminal ID and the acquired terminal ID. Information including the group ID (hereinafter, "terminal-side request information") is transmitted to the information sharing server 5.

Here, for example, the recording unit 14 of the terminal device 105 is used as a chat group for displaying information by a predetermined operation performed by "A5", who is the cleaning staff on the second floor of FIG. 1, via the touch pad 12 of the terminal device 105. When one chat group of the "guest room group (2F)" identified by "IDg005" in the stored "group ID" = "IDg003, IDg005, IDg007, ..." is selected, the control unit of the terminal device 105. 15 acquires the "terminal ID" = "IDt005" stored in its own recording unit 14, and also acquires the "group ID" = "IDg005" that identifies the selected chat group described above. , "Terminal side request information" including the acquired "terminal ID" = "IDt005" and "group ID" = "IDg005" is transmitted to the information sharing server 5.

On the other hand, the control unit 53 of the information sharing server 5 receives the "terminal-side request information" transmitted from the terminal device 1, refers to the chat history information of FIG. 9, and receives the above-mentioned "terminal-side request information". Acquires the group name information and chat information associated with the same group ID as the group ID included in "Information", and displays the group chat display screen of FIG. 10 based on the acquired group name information and chat information. The terminal device 1 generates the screen information for the terminal, and the generated screen information and the information including the terminal ID included in the above-mentioned received "terminal side request information" (hereinafter, "server side response information"). Send to.

Here, for example, as the chat information associated with "group ID" = "IDg005" in FIG. 9, only "07011400-IDt001-GG arrived, is the cleaning completed on the second floor?" Is stored. The case where there is is explained. In this case, the control unit 53 of the information sharing server 5 receives the "terminal side request information" transmitted from the terminal device 1, refers to the chat history information of FIG. 9, and receives the above-mentioned "terminal side request". "Group ID" = "IDg005" included in "Information" and "Group name information" = "Room group (2F)" and "Chat information" = "07011400-IDt001-GG" associated with the same group ID Arrived, is the cleaning completed on the 2nd floor? ”, And based on the acquired group name information and chat information, screen information for displaying the group chat display screen in FIG. 10 is generated and generated. The displayed screen information and the "server-side response information" including the "terminal ID" = "IDt005" included in the above-mentioned received "terminal-side request information" are transmitted to the terminal device 1.

The screen information generation method is arbitrary, but for example, the name of the group specified in the acquired group name information is displayed in the group name display field 61 of FIG. 10, and the above-mentioned acquired chat information is also displayed. Generates screen information in which the information corresponding to is displayed in the text display field 62. More specifically about the text display field 62, for example, referring to the user information of FIG. 6, the name information and the occupation type associated with the same terminal ID as the "terminal ID" included in the above-mentioned acquired chat information. After specifying the information, it is included in the specified name information and occupation information, the date and time indicated by the "information indicating the date and time when the information was shared" included in the above-mentioned acquired chat information, and the above-mentioned acquired chat information. Generate screen information that displays the "shared information" that has been posted. If the above-mentioned "N" is stored in the above-mentioned acquired chat information instead of the "terminal ID", the name information and the occupation information cannot be specified, so the screen information in which the name information and the occupation information are omitted is omitted. To generate.

Here, for example, the name of the group specified by the above-mentioned acquired "group name information" = "guest room group (2F)" is displayed in the group name display field 61 of FIG. 10, and the above-mentioned acquired chat information is also displayed. Generates screen information in which the information corresponding to is displayed in the text display field 62. For more details about the text display field 62, for example, referring to the user information in FIG. 6, the above-mentioned acquired "chat information" = "07011400-IDt001-GG has arrived, has the second floor been cleaned? "Name information" = "A1" and "Job type information" = "Front" associated with the same terminal ID as "Terminal ID" = "IDt001" included in "?" "Name information" = "A1" and "Job type information" = "Front", "7/11" indicated by "07011400" which is "information indicating the date and time when the information was shared" included in the above-mentioned acquired chat information. Generates screen information that displays "14:00" and "shared information" = "GG arrived, is cleaning completed on the second floor?" Included in the above-mentioned acquired chat information. ..

On the other hand, the recording unit 14 of the terminal device 1 receives the "server-side response information" transmitted from the information sharing server 5, and the terminal ID included in the received "server-side response information" and its own. When the terminal IDs recorded in the recording unit 14 match each other, it is regarded as "server-side response information" to itself, and is based on the screen information included in the received "server-side response information". Then, a group chat display screen is generated and displayed on the display 13.

Here, for example, the recording unit 14 of the terminal device 105 receives the "server-side response information" transmitted from the information sharing server 5, and the "terminal ID" included in the received "server-side response information". "=" IDt005 "and the" terminal ID "=" IDt005 "recorded in the self-recording unit 14 are mutually matched, so that the reception is regarded as" server-side response information "to the self. Based on the screen information included in the "server-side response information", the group chat display screen shown in FIG. 10 is generated and displayed on the display 13. This ends the chat information display process.

(Processing-Sign-related processing)
Next, the sign-related processing will be described. FIG. 11 is a flowchart of the sign-related processing (steps are abbreviated as “S” in the following description of each processing), and FIG. 12 is a plan view of a part of the second floor of the building of FIG. The "predictive processing" is generally a process performed by each device of the disaster prevention system 100, and is, for example, a process related to disaster prevention when a fire sign occurs. The timing of executing this sign-related process is arbitrary, but for example, when the power of each device of the disaster prevention system 100 is turned on, the execution is repeatedly started, and the execution of the sign-related process is started from the point where the execution is started. This will be described (the same applies to other processes described later). Here, for example, as shown in FIG. 12, a case where a fire breaks out in room 1, which is a guest room on the second floor of a building, will be described as an example (the same applies to other processes described later). Further, the communication between the devices performed in each step is performed via the communication unit, but since a known method can be applied to a specific method of this communication, the description thereof will be omitted.

In SA1 of FIG. 11, the control unit (not shown) of the disaster prevention receiver 3 determines whether or not a sign of fire has occurred. Specifically, although it is arbitrary, for example, the detector 2 of FIGS. 1 to 3 is configured as shown below, and the determination is made based on the signal transmitted from the detector 2.

Specifically, it is assumed that the detector 2 is configured as a so-called smoke detector that detects a sign of a fire or the occurrence of a fire based on the concentration of smoke, and the recording unit (not shown) of the detector 2 is used. , The threshold for predictive detection and the threshold for fire detection are stored. The “threshold value for detecting a sign” is a threshold value used for detecting a sign of a fire, and is a value to be compared with, for example, the concentration of smoke measured by the sensor 2. The "fire detection threshold" is a threshold used for detecting a fire, for example, a value to be compared with the smoke concentration measured by the sensor 2, and is higher than the above-mentioned "predictive detection threshold". It is set to a large value. Then, the sensor 2 operates as follows, for example.

Specifically, the control unit (not shown) of the sensor 2 compares the smoke concentration measured by itself with the "predictive detection threshold" stored in the recording unit, and the measured smoke concentration is ". If it is lower than the "predictive detection threshold", it is determined that no fire sign has occurred, while if the measured smoke concentration is equal to or higher than the "predictive detection threshold", a fire sign has occurred. After determining that the fire has occurred (that is, after detecting that a sign of fire has occurred), the equipment ID recorded in the self-recording unit is acquired, and the sensor side precursor signal including the acquired equipment ID is obtained. (A signal indicating that a sign of fire has occurred) is generated and transmitted to the disaster prevention receiver 3.

Further, the control unit (not shown) of the sensor 2 compares the smoke concentration measured by itself with the "fire detection threshold" stored in the recording unit, and the measured smoke concentration is "fire detection". If it is lower than the "threshold", it is determined that no fire has occurred, while if the measured smoke concentration is equal to or higher than the "fire detection threshold", it is determined that a fire has occurred. (That is, after detecting that a fire has occurred), the equipment ID recorded in its own recording unit is acquired, and the sensor side fire signal (signal indicating that a fire has occurred) including the acquired equipment ID. ) Is generated and transmitted to the disaster prevention receiver 3.

More specifically about the processing of SA1, the control unit of the disaster prevention receiver 3 determines that no fire sign has occurred when the sensor side sign signal is not received from the sensor 2 (NO of SA1). ), SA1 is repeatedly executed until it is determined that a sign of fire has occurred. Further, when the sensor side sign signal is received from the sensor 2, it is determined that a fire sign has occurred (YES of SA1), and the process shifts to SA2.

Here, for example, as shown in FIG. 12, when a fire breaks out in the room No. 1 which is the guest room on the second floor, the concentration of smoke in the room No. 1 gradually increases, and the measurement is performed by the sensor 201. When the smoke concentration becomes equal to or higher than the "predictive detection threshold" recorded in the recording unit of the sensor 201, the sensor 201 determines that a fire sign has occurred and then records itself. The "equipment ID" = "IDd201" recorded in the unit is acquired, and a sensor-side precursor signal including the acquired "equipment ID" = "IDd201" is generated and transmitted to the disaster prevention receiver 3. Then, the control unit of the disaster prevention receiver 3 receives the detector-side precursor signal from the detector 201, and determines that the alarm of fire has occurred (YES in SA1).

In SA2 of FIG. 11, the control unit (not shown) of the disaster prevention receiver 3 acquires the equipment ID included in the detector-side precursor signal received by SA1, and the receiver-side precursor signal (fire) including the acquired equipment ID. A signal indicating that a sign has occurred) is generated, and the generated receiver-side sign signal is transmitted to the disaster prevention notification server 4.

Here, for example, the “equipment ID” = “IDd201” included in the sensor-side precursor signal received by SA1 is acquired, and the receiver-side precursor signal including the acquired “equipment ID” = “IDd201” is generated. It is transmitted to the disaster prevention notification server 4.

On the other hand, in SB1 of FIG. 11, the control unit 43 of the disaster prevention notification server 4 receives the receiver-side precursor signal transmitted by SA2.

Here, for example, a receiver-side precursor signal including "equipment ID" = "IDd201" is received.

In SB2 of FIG. 11, the control unit 43 of the disaster prevention notification server 4 identifies a place (that is, a sign place) where a sign of fire has occurred. Specifically, although it is arbitrary, for example, referring to the equipment information in FIG. 5, the installation location information associated with the same equipment ID as the equipment ID included in the receiver-side precursor signal received by SB1 can be obtained. Identify and identify the location indicated by the identified installation location information as a precursor location.

Here, for example, referring to the equipment information of FIG. 5, the “installation location information” associated with the same equipment ID as the “equipment ID” = “IDd201” included in the receiver-side precursor signal received by SB1. "=" Room 1 on the 2nd floor (Room 1) "is specified, and the specified" Installation location information "=" Room 1 on the 2nd floor of the building "is the location indicated by" Room 1 on the 2nd floor ". Is specified as a sign place.

In SB3 of FIG. 11, the control unit 43 of the disaster prevention notification server 4 determines a sign location signal (a sign of a fire has occurred and a location where the sign of the fire has occurred) including the sign location information indicating the sign location specified by SB2. The signal shown) is transmitted to the information sharing server 5.

Here, for example, in the above-mentioned SB2, "Room 1 which is a guest room on the second floor of the building" is specified as a sign place. Therefore, in SB3, the sign place information indicating "Room 1 which is a guest room on the second floor of the building" is specified. As a sign, a sign location signal including "predictive location information" = "guest room on the second floor (room 1)" is transmitted to the information sharing server 5.

On the other hand, in SC1 of FIG. 11, the control unit 53 of the information sharing server 5 receives the sign location signal transmitted by SB3.

Here, for example, a sign location signal including "predictive location information" = "room on the second floor (room 1)" is received.

In SC2 of FIG. 11, the control unit 53 of the information sharing server 5 notifies the user belonging to the chat group related to the sign location that a sign of fire has occurred. Specifically, although it is optional, for example, the chat information in the chat history information of FIG. 9 is stored, and the notification that the chat information is stored is performed.

<Storing chat information>
First, regarding the storage of chat information, the notification destination group specific information in FIG. 8 is referred to, and the chat information is associated with the fire occurrence location information indicating the same location as the precursor location information included in the precursor location signal received by SC1. As the chat information associated with the same group ID as the above-mentioned specified group ID in the chat history information of FIG. 9, after specifying the specified group ID and specifying the current date and time by an arbitrary method. , The above-mentioned information indicating the specified current date and time, the above-mentioned "N", and the information in which the fire sign information indicating that a fire sign has occurred are stored as chat information.

When the sign location information included in the sign location signal received by SC1 is information indicating a specific room number in the guest room on the second floor such as "room on the second floor (room 1)", it is shown in FIG. Processing is performed assuming that comprehensive information including the room concerned indicates the same place, such as "fire occurrence location information" = "room on the second floor".

Further, the fire sign information stored as chat information is arbitrary, but for example, information indicating a sign location (for example, sign location information included in the sign location signal received by SC1) and a fire sign have occurred. Therefore, we will use information that prompts confirmation of a fire at a sign location (for example, message information such as "Fear of fire, please confirm").

Here, for example, referring to the notification destination group specific information in FIG. 8, the same place as "predictive place information" = "room on the second floor (room 1)" included in the sign place signal received by SC1 is shown. The "group ID" = "IDg005" associated with the "second floor guest room", which is the information on the location of the fire, is specified, and the current date and time is, for example, "July 01, 18:00" by any method. In the chat history information of FIG. 9, as the chat information associated with the same group ID as the above-mentioned specified group ID, there is a risk of fire in the guest room (Room 1) on the N-2nd floor of "07011800-N-2". Please check. " Regarding the fire sign information stored as this chat information, "There is a risk of fire in the room on the 2nd floor (Room 1), please check", the information indicating the sign location is "Room on the 2nd floor (Room 1)". (That is, the sign location information included in the sign location signal received by SC1) and the information that prompts you to confirm the fire at the sign location because a fire sign has occurred (that is, "Fear of fire, please check". , Etc.) will be included.

<Notification that chat information has been stored>
Next, regarding the notification that the chat information has been stored, in the same manner as in the case of "<Chat information storage>", the notification destination group specific information in FIG. 8 is referred to, and the sign location signal received by SC1 is used. After identifying the group ID associated with the fire occurrence location information indicating the same location as the included sign location information, a push notification signal including the identified group ID (new information is stored as chat information). A signal indicating that it has been shared and shared) is transmitted to the terminal device 1.

Here, for example, referring to the notification destination group specific information in FIG. 8, the same place as "predictive place information" = "room on the second floor (room 1)" included in the sign place signal received by SC1 is shown. After specifying the "group ID" = "IDg005" associated with the "second floor guest room" which is the fire occurrence location information, the push notification signal (chat) including the specified "group ID" = "IDg005" A signal indicating that new information is stored and shared as information) is transmitted to the terminal device 1.

On the other hand, when the control unit 15 of the terminal device 1 receives the push notification signal, the control unit 15 compares the group ID included in the received push notification signal with the group ID recorded in its own recording unit 14, and receives the push notification signal. If the group ID included in the push notification signal matches any of the group IDs recorded in the own recording unit 14, it means that the push notification information (new information is stored and shared as chat information). The information to be shown) is displayed on the display 13. The push notification here is optional, but for example, by displaying text information or image information including information indicating a chat group identified by the group ID included in the received push notification signal on the display 13. The user may be notified of the chat group in which new information is stored and shared as chat information. In addition to displaying this push notification information, the vibration function of the terminal device 1 is turned on, and a predetermined notification sound or notification sound is output via a speaker (not shown) of the terminal device 1, which is newly used as chat information. Information may be stored and shared with the user.

Here, for example, when the control unit 15 of the terminal devices 101 to 107 receives the push notification signal including the “group ID” = “IDg005”, the “group ID” = “IDg005” included in the received push notification signal. Is compared with the group ID (FIG. 4) recorded in the self-recording unit 14, but the terminal devices 101, 105, 106 include the “group ID” = “IDg005” included in the received push notification signal. Since the same group ID as is recorded in the own recording unit 14, the push notification information is displayed on the display 13. In this case, the text information "guest room group (2F)" is also displayed and notified as information indicating the chat group identified by "group ID" = "IDg005" included in the received push notification signal. Since the terminal devices 102 to 104, 107 do not record the same group ID as the "group ID" = "IDg005" included in the received push notification signal in their own recording unit 14, they display the push notification information. Will not.

FIG. 13 is a diagram illustrating a group chat display screen. The user of the terminal device 1 who visually recognizes the above-mentioned push notification information recognizes that new information is stored and shared as chat information and that the chat group in which new information is stored and shared is recognized, and "chat information". As described in "Display processing", when the chat group in which the above-mentioned new information is stored and shared is selected as the chat group for displaying the information by the predetermined operation performed via the touch pad 12, the terminal device 1 The control unit 15 of FIG. 13 communicates with respect to the “terminal-side request information” and the “server-side response information” as described above, and then displays, for example, the group chat display screen of FIG. 13 on the display 13.

Here, for example, the user of the terminal device 105 who has visually recognized the above-mentioned push notification information, "A5", who is the cleaning staff on the second floor, has stored and shared new information as chat information, and new information. Recognizes that the chat group in which is stored and shared is the "chat group (2F)", and displays the information by a predetermined operation performed via the touch pad 12 as described in "Chat information display processing". As a chat group to be used, a chat group of "guest room group (2F)" identified by "IDg005" in "group ID" = "IDg003, IDg005, IDg007, ..." Stored in the recording unit 14 of the terminal device 105. When one is selected, the control unit 15 of the terminal device 105 transmits "terminal-side request information" including "terminal ID" = "IDt005" and "group ID" = "IDg005" to the information sharing server 5. ..

On the other hand, the control unit 53 of the information sharing server 5 receives the "terminal-side request information" transmitted from the terminal device 1, refers to the chat history information of FIG. 9, and receives the above-mentioned "terminal-side request information". "Group ID" = "IDg005" included in "Information" and "Group name information" = "Room group (2F)" associated with the same group ID, "Chat information" = "07011400-IDt001-GG" Arrived, have you completed cleaning on the 2nd floor? "," 07011401-IDt005-cleaning has been completed ", and" 07011800-N-2nd floor guest room (Room 1), please check for fear of fire. , And based on the acquired group name information and chat information, generate screen information for displaying the group chat display screen of FIG. 13, the generated screen information, and the above-mentioned received "for terminal side request". By transmitting the "server-side response information" including the "terminal ID" = "IDt005" included in the "information", the group chat display screen of FIG. 13 is displayed on the display 13 of the terminal device 105. In addition, on the group chat display screen, in fact, by performing a predetermined operation (for example, swipe etc.) via the touch pad 12, "07011400-IDt001-GG arrived, the second floor has been cleaned. Information corresponding to "?" (See Fig. 10) and "07011401-IDt005-Cleaning completed" will also be displayed, but on the initial screen, it corresponds to the chat information stored most recently. The information to be used may be displayed at a position where it is easy to see (for example, a position closer to the upper side on the screen).

In addition, when "A1" in charge of the front desk and "A6" in charge of the equipment on the second floor, who are users of the terminal devices 101 and 106 who visually recognize the above-mentioned push notification information, perform the same operation as "A5", FIG. The group chat display screen of is displayed on the terminal devices 101 and 106. The terminal devices 101, 105, and 106 here may be interpreted as corresponding to the "first mobile terminal".

In SC3 of FIG. 11, the control unit 53 of the information sharing server 5 determines whether or not to give an instruction to extinguish a fire with a fire extinguisher. Specifically, although it is arbitrary, for example, the information input by each user in the above-mentioned "chat information storage process" is stored in the chat information in the chat history information of FIG. 9, that is, the employee of the hotel Considering that the information about the fire is stored in the chat information when the information about the fire is input, the chat information is monitored and the following processing is performed. The chat information to be monitored here is arbitrary, and for example, all chat information may be monitored, or to the chat group to which the user who has notified that a sign of fire has occurred in SC2 belongs. The associated chat information may be monitored, but in the present embodiment, the latter case will be illustrated and described.

Specifically, the control unit 53 of the information sharing server 5 refers to the chat history information of FIG. 9 and identifies the group ID in which the chat information is stored in "<Storing chat information>" of SC2 (that is, "" (Specify the group ID specified in "Storage of chat information>"), and specify the chat group identified by the specified group ID as the chat group to be monitored. Next, in the chat history information of FIG. 9, the chat information associated with the group ID that identifies the chat group to be monitored described above is monitored, and the chat is performed in "<Storing chat information>" of SC2. After storing the information, it is determined whether or not the information indicating that the fire has been confirmed (in the present embodiment, for example, the information including the words "fire" or "fire") is stored. If it is determined that the information indicating that the fire has been confirmed is not stored, the fire extinguisher is instructed to extinguish the fire, assuming that the fire has not actually started because there is a possibility of an erroneous report by the sensor 2. SC3 is repeatedly executed until it is determined that there is no fire (NO in SC3) and it is determined that the fire extinguisher is instructed to extinguish the fire. In this case, it is determined that the fire extinguisher is instructed to extinguish the fire within a predetermined time (for example, 10 to 20 minutes) from the time when the chat information is stored in "<Storing chat information>" of SC2. If not, the process may be terminated. On the other hand, if it is determined that the information indicating that the fire has been confirmed is stored, it is determined that the fire extinguisher is instructed to extinguish the fire as if the fire was actually occurring (YES in SC3), and the system shifts to SC4. do.

Here, for example, the user "A6", who is in charge of equipment on the second floor, visits room 1, which is the guest room on the second floor in FIG. 12, after visually recognizing the group chat display screen of FIG. 13 displayed on SC2. As a chat group for sharing information by a predetermined operation performed via the touch pad 12 after confirming a fire, a chat group "room group (2F)" (that is, a chat group corresponding to the group chat display screen of FIG. 13) (that is, After selecting the "chat group (2F)" identified by "IDg005" in the "group ID" = "IDg004, IDg005, IDg007, ..." Stored in the recording unit 14 of the terminal device 106, " When "confirmed fire" is input as the information to be shared by the guest room group (2F), the control unit 15 of the terminal device 106 has "terminal ID" = "IDt006", "group ID" = "IDg005", And "input information" = "terminal side storage information" including "confirmed fire" is transmitted to the information sharing server 5.

On the other hand, the control unit 53 of the information sharing server 5 receives the "terminal-side storage information" transmitted from the terminal device 1, and sets, for example, "July 01, 18:05" as the current date and time by an arbitrary method. After specifying, based on the specified current date and time and the above-mentioned received "terminal storage information", "chat information" in the chat history information in FIG. 9 = "070111805-IDt006-a fire has been confirmed." To store.

In this case, in SC3 of FIG. 11, the control unit 53 of the information sharing server 5 refers to the chat history information of FIG. 9, and stores the chat information in the “<storage of chat information>” of SC2. "IDg005" is specified, and the chat group of the "guest room group (2F)" identified by the specified group ID is specified as the chat group to be monitored. Next, in the chat history information of FIG. 9, the chat information associated with the "group ID" = "IDg005" that identifies the chat group of the "room group (2F)" to be monitored described above is monitored. However, after storing "Chat information" = "There is a risk of fire in the guest room (Room 1) on the N-2nd floor (Room 1), please check" in "<Chat information storage>" of SC2, then "Chat information" = Since "070111805-IDt006-confirmed fire" is stored and the chat information contains the word "fire", it is determined that the information indicating that the fire has been confirmed is stored. Above, it is determined that the fire extinguisher is instructed to extinguish the fire (YES in SC3).

FIG. 14 is a diagram illustrating a group chat display screen. After "070111805-IDt006-confirmed a fire" is stored as the chat information in the chat history information of FIG. 9, the user belonging to the chat group of the "room group (2F)" displays the information. When "Guest room group (2F)" is selected, the above-mentioned "chat information display process" is executed, and "070111805-IDt006-fire breakout is confirmed on the display 13 of the terminal device 1 carried by the user. The group chat display screen of FIG. 14 including the information corresponding to "" will be displayed.

In SC4 of FIG. 11, the control unit 53 of the information sharing server 5 notifies the user belonging to the chat group corresponding to the initial fire extinguishing group of the instruction of extinguishing the fire with the fire extinguisher. Specifically, although it is arbitrary, for example, as in the case of SC2, the chat information in the chat history information of FIG. 9 is stored and the notification that the chat information is stored is performed.

<Storing chat information>
First, regarding the storage of chat information, refer to the chat group identification information in FIG. 7, specify the group ID that identifies the "initial fire extinguishing group", and specify the current date and time by any method. In the chat history information of FIG. 9, as the chat information associated with the same group ID as the above-mentioned specified group ID, the above-mentioned information indicating the specified current date and time, the above-mentioned "N", and extinguishing a fire with a fire extinguisher. Fire extinguishing device that instructs fire extinguishing information Stores information that correlates fire extinguishing instruction information as chat information.

The fire extinguisher fire extinguishing instruction information stored as chat information is arbitrary, but is included in the information indicating the sign location (for example, the sign location signal received by SC1) in the same manner as the fire sign information described in SC2. Information including the sign location information) will be used.

Here, for example, referring to the chat group identification information of FIG. 7, the "group ID" = "IDg008" that identifies the "initial fire extinguishing group" is specified, and the current date and time is, for example, "07" by any method. After specifying "18:05 on the 01st of the month", in the chat history information of FIG. 9, "070111805-" is used as the chat information associated with the same group ID as the above-mentioned specified "group ID" = "IDg008". Please extinguish the fire in the guest room (Room 1) on the N-2 floor with a fire extinguisher. " Regarding the fire extinguisher fire extinguishing instruction information stored as this chat information, "Please extinguish the fire in the 2nd floor guest room (Room 1) with a fire extinguisher", it is the information indicating the sign location "2nd floor guest room (room 1). Room 1) ”(that is, the sign location information included in the sign location signal received by SC1) is included.

<Notification that chat information has been stored>
Next, regarding the notification that the chat information has been stored, the group that identifies the "initial fire extinguishing group" by referring to the chat group specific information in FIG. 7 in the same manner as in the case of "<Chat information storage>". After specifying the ID, a push notification signal including the specified group ID is transmitted to the terminal device 1.

Here, for example, with reference to the chat group specific information of FIG. 7, after specifying the “group ID” = “IDg008” that identifies the “initial fire extinguishing group”, the specified “group ID” = “IDg008”. A push notification signal including the above is transmitted to the terminal device 1.

On the other hand, when the control unit 15 of the terminal device 1 receives the push notification signal, the control unit 15 performs the same processing as that described in SC2, appropriately displays the push notification information on the display 13, and also explains in SC2. Similar to the case, information indicating the chat group identified by the group ID included in the push notification signal is also displayed.

Here, for example, the terminal devices 101 to 107 receive the push notification signal including the "group ID" = "IDg008", but as shown in FIG. 4, only the terminal devices 102 and 104 have the "group ID" = " Since "IDg008" is stored, the terminal devices 102 and 104 display the push notification information on the display 13, and "group ID" included in the push notification signal = "IDg008" as information indicating a chat group identified by "IDg008". The text information "Initial fire extinguishing group" is also displayed and notified.

FIG. 15 is a diagram illustrating a group chat display screen. The user of the terminal device 1 who visually recognizes the above-mentioned push notification information recognizes that new information is stored and shared as chat information and that the chat group in which new information is stored and shared is recognized, and "chat information". As described in "Display processing", when the chat group in which the above-mentioned new information is stored and shared is selected as the chat group for displaying the information by the predetermined operation performed via the touch pad 12, the terminal device 1 The control unit 15 of FIG. 15 communicates with respect to the “terminal-side request information” and the “server-side response information” as described above, and then displays, for example, the group chat display screen of FIG. 15 on the display 13.

Here, for example, "A4" in charge of cloak, who is a user of the terminal device 104 who has visually recognized the above-mentioned push notification information, has stored and shared new information as chat information, and new information is stored. As a chat group that recognizes that the shared chat group is the "initial fire extinguishing group" and displays information by a predetermined operation performed via the touch pad 12 as described in "chat information display processing". When one chat group of the "initial fire extinguishing group" identified by "IDg008" in "group ID" = "IDg001, IDg007, IDg008, ..." Stored in the recording unit 14 of the terminal device 104 is selected. The control unit 15 of the terminal device 104 transmits "terminal-side request information" including "terminal ID" = "IDt004" and "group ID" = "IDg008" to the information sharing server 5.

Here, for example, as the chat information associated with "group ID" = "IDg008" in FIG. 9, only "Please extinguish the fire in the guest room (Room 1) on the 2nd floor (Room 1) 07011805-N with a fire extinguisher". The case where it is stored will be described. In this case, the control unit 53 of the information sharing server 5 receives the "terminal side request information" transmitted from the terminal device 1, refers to the chat history information of FIG. 9, and receives the above-mentioned "terminal side request". "Group ID" = "IDg008" included in "Information" and "Group name information" = "Initial fire extinguishing group" and "Chat information" = "070111805-N-2nd floor guest room" associated with the same group ID Please extinguish the fire in (Room 1) with a fire extinguisher ”, and based on the acquired group name information and chat information, generate screen information for displaying the group chat display screen of FIG. The display of the terminal device 104 by transmitting the generated screen information and the "server-side response information" including the "terminal ID" = "IDt004" included in the above-mentioned received "terminal-side request information". The group chat display screen of FIG. 15 is displayed on 13.

When the Belstaff "A2" who is the user of the terminal device 102 who visually recognizes the above-mentioned push notification information performs the same operation as the "A4", the group chat display screen of FIG. 15 is displayed on the terminal device 102. Will be done.

In this case, the users "A2" and "A4" belonging to the initial fire extinguishing group extinguish the fire with a fire extinguisher in the room No. 1 which is the guest room on the second floor by visually recognizing the group chat display screen of FIG. Recognizing the need, he visited Room 1, which is the guest room on the second floor shown in FIG. 12, and extinguished the fire using a fire extinguisher.

In SC5 of FIG. 11, the control unit 53 of the information sharing server 5 determines whether or not to give an instruction to extinguish a fire with a fire hydrant. Specifically, although it is arbitrary, for example, the information input by each user in the above-mentioned "chat information storage process" is stored in the chat information in the chat history information of FIG. 9, that is, the employee of the hotel (that is, the employee of the hotel ( For example, when a user belonging to the initial fire extinguishing group (such as a user) inputs information related to fire extinguishing, the chat information is monitored and the following processing is performed in consideration of the fact that the information related to fire extinguishing is stored in the chat information. The chat information to be monitored here is arbitrary, and for example, all chat information may be monitored, or to the chat group to which the user who has notified the instruction to extinguish the fire with the fire extinguisher in SC4 belongs. The associated chat information may be monitored, but in the present embodiment, the latter case will be illustrated and described.

Specifically, the control unit 53 of the information sharing server 5 refers to the chat history information of FIG. 9 and identifies the group ID in which the chat information is stored in "<Storing chat information>" of SC4 (that is, "" (Specify the group ID specified in "Storage of chat information>"), and specify the chat group identified by the specified group ID as the chat group to be monitored. Next, in the chat history information of FIG. 9, the chat information associated with the group ID that identifies the chat group to be monitored described above is monitored, and the chat is performed in "<Storing chat information>" of SC4. After storing the information, it is determined whether or not the information indicating that it is difficult to extinguish the fire by the fire extinguisher (in the present embodiment, for example, the information including the word "difficult" or "difficult") is stored. If it is determined that the information indicating that the fire is difficult to extinguish is not stored, it is determined that the fire extinguishing plug is not instructed to extinguish the fire (NO of SC5), and the fire extinguishing plug is instructed to extinguish the fire. SC5 is repeatedly executed until this is done. In this case, it is not determined that the fire extinguishing instruction is given by the fire hydrant within a predetermined time (for example, 20 to 30 minutes) from the time when the chat information is stored in "<Storing chat information>" of SC5. In that case, the process may be terminated by assuming that the fire extinguisher has been extinguished by extinguishing the fire. In addition, if it is determined that information indicating that it is difficult to extinguish the fire is stored, it is determined that the fire extinguishing device is insufficient to extinguish the fire and the fire is not extinguished. YES of SC5), shift to SC6.

Here, for example, when the user "A4" in charge of the cloak visits room 1 which is the guest room on the second floor in FIG. 12 and extinguishes the fire with a fire extinguisher, but does not extinguish the fire. , "Initial fire extinguishing group" after selecting "initial fire extinguishing group" which is a chat group corresponding to the group chat display screen of FIG. 15 as a chat group for sharing information by a predetermined operation performed via the touch pad 12. When "fire extinguishing is difficult" is input as the information to be shared by, the control unit 15 of the terminal device 104 has "terminal ID" = "IDt004", "group ID" = "IDg008", and "input information" =. "Information for storage on the terminal side" including "difficult to extinguish a fire" is transmitted to the information sharing server 5.

On the other hand, the control unit 53 of the information sharing server 5 receives the "terminal-side storage information" transmitted from the terminal device 1, and sets, for example, "July 01, 18:10" as the current date and time by an arbitrary method. After specifying, "chat information" = "07011810-IDt004-fire extinguishing is difficult" in the chat history information of FIG. 9 is stored based on the specified current date and time and the above-mentioned received "terminal side storage information". do.

In this case, in SC5 of FIG. 11, the control unit 53 of the information sharing server 5 refers to the chat history information of FIG. 9, and stores the chat information in the “<storage of chat information>” of SC4. "IDg008" is specified, and the chat group of the "initial fire extinguishing group" identified by the specified group ID is specified as the chat group to be monitored. Next, in the chat history information of FIG. 9, the chat information associated with the "group ID" = "IDg008" that identifies the chat group of the "initial fire extinguishing group" to be monitored described above is monitored. After storing "Chat information" = "Please extinguish the fire in the guest room (Room 1) on the 2nd floor (Room 1) with a fire extinguisher" in "<Storage of chat information>" of SC4, "Chat information" = "07011810-IDt004-Fire extinguishing is difficult" is stored, and since the chat information contains the word "difficult", it is determined that information indicating that fire extinguishing is difficult is stored. Then, it is determined that the fire extinguishing plug is instructed to extinguish the fire (YES of SC5).

FIG. 16 is a diagram illustrating a group chat display screen. After "07011810-IDt004 is difficult to extinguish" is stored as the chat information of the chat history information in FIG. 9, the user belonging to the chat group of the "initial fire extinguishing group" displays the information as the "initial fire extinguishing group". When "Group" is selected, the above-mentioned "chat information display process" is executed, and the display 13 of the terminal device 1 carried by the user includes information corresponding to "07011810-IDt004-fire extinguishing is difficult". 16 group chat display screens will be displayed.

In SC6 of FIG. 11, the control unit 53 of the information sharing server 5 notifies the user belonging to the chat group corresponding to the initial fire extinguishing group of the instruction of extinguishing the fire with the fire hydrant. Specifically, it is optional and is the same as the processing of SC4, and the chat information in the chat history information of FIG. 9 is stored and the notification that the chat information is stored is performed.

<Storing chat information>
First, regarding the storage of chat information, refer to the chat group identification information in FIG. 7, specify the group ID that identifies the "initial fire extinguishing group", and specify the current date and time by any method. In the chat history information of FIG. 9, as the chat information associated with the same group ID as the above-mentioned specified group ID, the above-mentioned information indicating the specified current date and time, the above-mentioned "N", and the fire extinguishing with a fire hydrant are used. Fire hydrant to be instructed Stores information in which fire extinguishing instruction information is associated with each other as chat information.

Here, for example, referring to the chat group specific information of FIG. 7, the “group ID” = “IDg008” that identifies the “initial fire extinguishing group” is specified, and the current date and time is, for example, “07” by any method. After specifying "18:10 on the 01st of the month", in the chat history information of FIG. 9, as the chat information associated with the same group ID as the above-mentioned specified "group ID" = "IDg008", "07011810-" Please extinguish the fire in the guest room (Room 1) on the N-2 floor with a fire hydrant. "

<Notification that chat information has been stored>
Next, regarding the notification that the chat information is stored, the terminal devices 102 and 104 display the push notification information 13 by performing the same processing as "<Notification that the chat information is stored>" of SC4. The text information "initial fire extinguishing group" is also displayed and notified as information indicating the chat group identified by "group ID" = "IDg008" included in the push notification signal.

FIG. 17 is a diagram illustrating a group chat display screen. As described in the "chat information display process", the user of the terminal device 1 who has visually recognized the push notification information described above is a new chat group that displays information by a predetermined operation performed via the touch pad 12. When a chat group in which information is stored and shared is selected, the control unit 15 of the terminal device 1 communicates with respect to "terminal-side request information" and "server-side response information" as described above. For example, the group chat display screen of FIG. 17 is displayed on the display 13.

Here, for example, as described in the "chat information display process", the "A4" in charge of the cloak, who is the user of the terminal device 104 who has visually recognized the push notification information, performs a predetermined operation via the touch pad 12. When one chat group of the "initial fire extinguishing group" is selected as the chat group for displaying information, the control unit 15 of the terminal device 104 has "terminal ID" = "IDt004" and "group ID" = "IDg008". "Information for terminal request" including the above is transmitted to the information sharing server 5.

On the other hand, the control unit 53 of the information sharing server 5 receives the "terminal-side request information" transmitted from the terminal device 1, refers to the chat history information of FIG. 9, and receives the above-mentioned "terminal-side request information". "Group ID" = "IDg008" included in "Information" and "Group name information" = "Initial fire extinguishing group" associated with the same group ID, and "Chat information" = "070111805-N-2nd floor guest room" Please extinguish the fire in (Room 1) with a fire extinguisher, "07011810-IDt004 is difficult to extinguish", and "Extinguish the fire in the guest room (Room 1) on the 07011810-N-2 floor with a fire extinguisher. , And based on the acquired group name information and chat information, generate screen information for displaying the group chat display screen of FIG. 17, the generated screen information, and the above-mentioned received "for terminal side request". By transmitting the "server-side response information" including the "terminal ID" = "IDt004" included in the "information", the group chat display screen of FIG. 17 is displayed on the display 13 of the terminal device 104.

When the Belstaff "A2" who is the user of the terminal device 102 who visually recognizes the above-mentioned push notification information performs the same operation as the "A4", the group chat display screen of FIG. 17 is displayed on the terminal device 102. Will be done.

In this case, the users "A2" and "A4" belonging to the initial fire extinguishing group need to extinguish the fire with a fire hydrant in the room No. 1 which is the guest room on the second floor by visually recognizing the group chat display screen of FIG. Recognizing that there is, we will visit Room 1, which is the guest room on the second floor shown in FIG. 12, and extinguish the fire using a fire hydrant. This completes the sign-related processing.

(Treatment-Fire-related processing)
Next, fire-related processing will be described. FIG. 18 is a flowchart of fire-related processing, and FIG. 19 is a diagram illustrating a group chat display screen. The "fire-related process" is generally a process performed by each device of the disaster prevention system 100, and is, for example, a process related to disaster prevention in the event of a fire.

In SD1 of FIG. 18, the control unit (not shown) of the disaster prevention receiver 3 determines whether or not a fire has occurred. Specifically, it is arbitrary, but for example, the determination is made based on the reception of the above-mentioned sensor-side fire signal. Specifically, when the control unit of the disaster prevention receiver 3 does not receive the fire signal on the detector side from the detector 2, it is determined that no fire has occurred (NO of SD1), and a fire has occurred. SD1 is repeatedly executed until it is determined. Further, when the detector side fire signal is received from the detector 2, it is determined that a fire has occurred (YES of SD1), and the process shifts to SD2.

Here, for example, as shown in FIG. 12, when a fire breaks out in the room No. 1 which is the guest room on the second floor, the concentration of smoke in the room No. 1 gradually increases, and the measurement is performed by the sensor 201. When the smoke concentration becomes equal to or higher than the "fire detection threshold" recorded in the recording unit of the detector 201, the detector 201 determines that a fire has occurred and then sets it in its own recording unit. The recorded "equipment ID" = "IDd201" is acquired, and a sensor-side fire signal including the acquired "equipment ID" = "IDd201" is generated and transmitted to the disaster prevention receiver 3. Then, the control unit of the disaster prevention receiver 3 receives the fire signal on the sensor side from the sensor 201 and determines that a fire has occurred (YES in SD1).

In SD2 of FIG. 18, the control unit (not shown) of the disaster prevention receiver 3 acquires the equipment ID included in the detector-side fire signal received by SD1, and the receiver-side fire signal (fire) including the acquired equipment ID. A signal indicating that it has occurred) is generated, and the generated fire signal on the receiver side is transmitted to the disaster prevention notification server 4.

Here, for example, the “equipment ID” = “IDd201” included in the detector-side fire signal received by SD1 is acquired, and the receiver-side fire signal including the acquired “equipment ID” = “IDd201” is generated. It is transmitted to the disaster prevention notification server 4.

On the other hand, in SE1 of FIG. 18, the control unit 43 of the disaster prevention notification server 4 receives the receiver-side fire signal transmitted by SD2.

Here, for example, a receiver-side fire signal including "equipment ID" = "IDd201" is received.

In SE2 of FIG. 18, the control unit 43 of the disaster prevention notification server 4 identifies the place where the fire occurred (that is, the place of the fire). Specifically, although it is arbitrary, for example, the fire location is specified in the same manner as in the case of SB2 in FIG.

Here, for example, referring to the equipment information of FIG. 5, the “installation location information” associated with the same equipment ID as the “equipment ID” = “IDd201” included in the receiver-side fire signal received by SE1. ”=“ Guest room on the 2nd floor (Room 1) ”is specified, and“ Room 1 which is the guest room on the 2nd floor of the building ”is the location indicated by the“ Installation location information ”=“ Guest room on the 2nd floor (Room 1) ”. Identify as a location.

In SE3 of FIG. 18, the control unit 43 of the disaster prevention notification server 4 outputs a occurrence location signal (a signal indicating that a fire has occurred and the location where the fire has occurred) including the occurrence location information indicating the occurrence location specified by SE2. It is transmitted to the information sharing server 5.

Here, for example, in SE2 described above, "Room 1 which is a guest room on the second floor of a building" is specified as a place of occurrence. Therefore, in SE3, information on a place of occurrence indicating "Room 1 which is a guest room on the second floor of a building". The occurrence location signal including "occurrence location information" = "room on the second floor (room 1)" is transmitted to the information sharing server 5.

On the other hand, in SF1 of FIG. 18, the control unit 53 of the information sharing server 5 receives the generation location signal transmitted by SE3.

Here, for example, the generation location signal including "occurrence location information" = "room on the second floor (room No. 1)" is received.

In SF2 of FIG. 18, the control unit 53 of the information sharing server 5 notifies the user belonging to the chat group related to the location of the fire that the fire has occurred. Specifically, although it is arbitrary, in the same manner as in SC2 of FIG. 11, for example, the chat information in the chat history information of FIG. 9 is stored, and the notification that the chat information is stored is performed. Since the processing here is the same as that of SC2 in FIG. 11, only a specific example will be described.

<Storing chat information>

Here, for example, referring to the notification destination group specific information in FIG. 8, the same place as the “occurrence place information” = “2nd floor guest room (room 1)” included in the generation place signal received by SF1 is shown. The "group ID" = "IDg005" associated with the "second floor guest room", which is the information on the location of the fire, is specified, and the current date and time is, for example, "July 01, 18:40" by any method. In the chat history information of FIG. 9, as the chat information associated with the same group ID as the above-mentioned specified group ID, "07011840-N-2nd floor guest room (Room 1) has a fire. Please call 119. "

<Notification that chat information has been stored>
Here, for example, referring to the notification destination group specific information in FIG. 8, the same place as the “occurrence place information” = “2nd floor guest room (room 1)” included in the generation place signal received by SF1 is shown. After specifying the "group ID" = "IDg005" associated with the "second floor guest room" which is the fire occurrence location information, the push notification signal (chat) including the specified "group ID" = "IDg005" The push notification information is displayed on the terminal devices 101, 105, and 106 by transmitting a signal (a signal indicating that new information is stored and shared as information) to the terminal device 1.

On the other hand, for example, as a chat group in which "A5", who is a user of the terminal device 105 who has visually recognized the above-mentioned push notification information, displays the information by a predetermined operation performed via the touch pad 12, "Guest room". When one chat group of "Group (2F)" is selected, the group chat display screen of FIG. 19 is displayed on the display 13. This completes the fire-related processing.

(Processing-Fire level judgment related processing)
Next, the fire level determination related processing will be described. FIG. 20 is a flowchart of a fire level determination-related process, and FIG. 21 is a diagram illustrating a group chat display screen. The "fire level determination-related process" is generally a process performed by each device of the disaster prevention system 100, and is, for example, a process related to disaster prevention when a fire is determined to have a fire level.

In SG1 of FIG. 20, the control unit (not shown) of the disaster prevention receiver 3 determines whether or not to determine the fire level for the occurrence of a fire. Specifically, it is arbitrary, but for example, it is determined based on whether or not a predetermined fire level determination condition is satisfied. The "predetermined fire level determination condition" is a condition for determining a fire to determine the fire level, and known conditions can be applied. However, in the present embodiment, the first to third fires are used. A case where the level judgment condition is used will be described. The "first fire level determination condition" is, for example, receiving a fire signal on the detector side from a plurality of detectors 2, and the "second fire level determination condition" is, for example, not shown in a building. By receiving a signal from the fire transmitter side indicating that the button of the known fire transmitter has been pressed by the user, the "third fire level determination condition" is provided in, for example, the disaster prevention receiver 3. Information indicating that the fire level determination button, which is not shown and is known, has been pressed by the user has been accepted. Specifically, the control unit of the disaster prevention receiver 3 determines that the occurrence of a fire is not determined by the fire level if none of the conditions of the first to third fire level determination conditions are met (NO of SG1). ), SG1 is repeatedly executed until it is determined that the occurrence of the fire is cut off. Further, when at least one of the first to third fire level determination conditions is satisfied, it is determined that the occurrence of a fire is to determine the fire level (YES in SG1), and the process proceeds to SG2.

Here, for example, as shown in FIG. 12, when a fire that broke out in room 1 on the second floor spreads to room 2, the concentration of smoke measured by the detectors 201 and 202 is the sensor 201. , 202, when the value exceeds the "fire detection threshold" recorded in the recording unit, the detectors 201 and 202 determine that a fire has occurred, and then, in the same manner as described above, the detectors 201 and 202. A side fire signal is generated and transmitted to the disaster prevention receiver 3. Then, the control unit of the disaster prevention receiver 3 receives the fire signal on the detector side from the detectors 201 and 202 and corresponds to the "first fire level determination condition", so that the occurrence of the fire is determined as the fire level. (YES of SG1).

In SG2 of FIG. 20, the control unit (not shown) of the disaster prevention receiver 3 generates a receiver-side fire level determination signal (a signal indicating that the fire level has been determined for the occurrence of a fire), and the generated receiver-side fire level. The determination signal is transmitted to the disaster prevention notification server 4. In this case, the disaster prevention receiver 3 may notify the fire by issuing a district bell, emergency broadcasting, or the like in the same manner as in the conventional case.

On the other hand, in SH1 of FIG. 20, the control unit 43 of the disaster prevention notification server 4 receives the receiver-side fire level determination signal transmitted by SG2.

In SH2 of FIG. 20, the control unit 43 of the disaster prevention notification server 4 is a fire level determination signal (a signal indicating information similar to the fire level determination signal on the receiver side, that is, indicating that the occurrence of a fire has been determined by the fire level. The signal) is transmitted to the information sharing server 5.

On the other hand, in SI1 of FIG. 20, the control unit 53 of the information sharing server 5 receives the fire level determination signal transmitted by SH2.

In SI2 of FIG. 20, the control unit 53 of the information sharing server 5 notifies all users belonging to the chat group corresponding to "all employees" that the fire level has been determined. Specifically, although it is arbitrary, in the same manner as in SC4 of FIG. 11, for example, the chat information in the chat history information of FIG. 9 is stored, and the notification that the chat information is stored is performed. Since the processing here is substantially the same as SC4 in FIG. 11, only a specific example will be described.

<Storing chat information>

Here, for example, referring to the chat group identification information in FIG. 7, the "group ID" = "IDg007" that identifies "all employees" is specified, and the current date and time is, for example, "07" by any method. After specifying "19:00 on the 01st of the month", in the chat history information of FIG. 9, as the chat information associated with the same group ID as the above-mentioned specified "group ID" = "IDg007", "07011900-" N-A fire broke out in the building, please guide evacuation. "

<Notification that chat information has been stored>

Here, for example, with reference to the chat group specific information in FIG. 7, after specifying the "group ID" = "IDg007" that identifies "all employees", the specified "group ID" = "IDg007". By transmitting the push notification signal including the above to the terminal device 1, the push notification information is displayed on the terminal devices 101 to 107.

On the other hand, for example, as a chat group in which the users of the terminal devices 101 to 107 who visually recognize the above-mentioned push notification information display the information by a predetermined operation performed via the touch pad 12, the chat group of "all employees" is set to 1. When individual items are selected, the group chat display screen of FIG. 21 is displayed on the display 13. This completes the fire level determination related processing.

(Effect of embodiment)
As described above, according to the present embodiment, a fire sign has occurred for the terminal device 1 (first mobile terminal) that is previously associated with the place indicated by the sign location information among the plurality of terminal devices 1. By transmitting fire sign information indicating fire extinguishing, and by transmitting information instructing fire extinguishing to a predetermined terminal device 1 (second mobile terminal) among a plurality of terminal devices 1, for example, a fire. At an early stage before the fire spreads, it is possible to notify some users (for example, employees who are related to the management side or the operation side of the facility to which the disaster prevention system 100 is applied) of the sign of a fire. In addition, since it can be used to extinguish a fire, it is possible to improve disaster prevention.

In addition, by transmitting information instructing the fire extinguisher to extinguish the fire, for example, the fire extinguisher, which is a fire extinguisher, can be specifically notified, so that the initial action of the fire extinguishing activity may be delayed due to the selection of the fire extinguisher. Can be prevented.

In addition, when receiving information indicating that it is difficult to extinguish a fire with a fire extinguisher, by transmitting information instructing fire extinguishing with a fire hydrant, for example, fire extinguishing activities can be carried out using appropriate equipment for extinguishing the fire. Since it can be hit, it is possible to improve disaster prevention.

May be resolved or only some of the above effects may be achieved.

(About distribution and integration)
Further, the above-mentioned configuration is a functional concept, and does not necessarily have to be physically configured as shown in the figure. That is, the specific form of dispersion or integration of each part is not limited to the one shown in the figure, and all or a part thereof can be functionally or physically dispersed or integrated in any unit. For example, the function of the disaster prevention notification server 4 may be incorporated into the disaster prevention receiver 3. In this case, the disaster prevention receiver 3 incorporating the function of the disaster prevention notification server 4 may be interpreted as corresponding to the "fire alarm system".

(Notification of information)
Further, in the above embodiment, in SC2 of FIG. 11, after performing each process of "<storage of chat information>" and "<notification that chat information is stored>", the user can use the touchpad 12 The case where the group chat display screen is displayed when the chat group for which information is displayed is selected by the predetermined operation performed via the above is not limited to this. For example, the group chat display screen may be displayed on the display 13 of the terminal device 1 regardless of the predetermined operation by the user.

Specifically, although it is arbitrary, for example, the control unit 15 of the terminal device 1 that has received the push notification signal after "<storage of chat information>" and "<notification that chat information has been stored>" of SC2. Compares the group ID included in the received push notification signal with the group ID recorded in its own recording unit 14, and the group ID included in the received push notification signal is recorded in its own recording unit 14. If it matches any of the group IDs, the push notification information may be displayed instead of displaying the push notification information, and the following processing may be performed. Specifically, the group ID included in the received push notification signal described above is acquired, and the terminal ID recorded in the own recording unit 14 is acquired, and then the acquired group ID and terminal ID are included. By transmitting the "terminal-side request information" to the information sharing server 5, the "server-side response information" is received and the received "server-side response" is received in the same manner as described in the "chat information display process". A group chat display screen is generated and displayed on the display 13 based on the "information". By processing in this way, it is possible to automatically display fire sign information and the like regardless of a predetermined operation by the user. The technique described here is applied to SC4 and SC6 in FIG. 11, SF2 in FIG. 18, and SG2 in FIG. 20, so that each information is automatically displayed on the terminal device 1 side in each step. It may be configured.

(About other features)
Further, the detector 2 is supposed to detect a sign of a fire or the occurrence of a fire, but the present invention is not limited to this. The detector 2 may transmit a predetermined physical quantity detected to the disaster prevention receiver 3 and detect a sign of fire or the occurrence of a fire based on the predetermined physical quantity received by the disaster prevention receiver 3.

Further, when the information sharing server 5 notifies the group chat in the next stage, the log of the group chat in the previous stage includes messages from the notification of the information sharing server 5 regarding the fire to the message regarded as the determination of the instruction. The log may be displayed in the next group chat. For example, when displaying "Please extinguish the fire in the 2nd floor guest room (Room 1) with a fire extinguisher" on the group chat display screen of the "initial fire extinguishing group" as shown in Fig. 15, "2nd floor guest room" is displayed in front of it. The message "Fear of fire, please check" to "Confirmed fire" in (Room 1) may be displayed as the log of the group chat in the previous stage.

In addition, a plurality or all of the messages of the chat group related to a certain property may be able to be confirmed by the administrator. Administrators may be able to retrieve messages across multiple chat groups related to a fire. For example, the information sharing server 5 stores information uniquely specified for each sign of fire, and assigns the uniquely specified information to the messages from the notification of the information sharing server 5 to the message regarded as the determination of the instruction. By doing so, it may be possible to acquire a message across a plurality of chat groups.
