DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] A linkage system 100 according to an embodiment of the present disclosure and a display system 2 included in the linkage system 100 will be described in detail with reference to the drawings. Note that each figure described in the following embodiment is a schematic diagram, and the size and thickness ratio of each component in each figure does not necessarily reflect the actual dimensional ratio. In addition, the embodiment and modified example described below are merely examples of the present disclosure, and the present disclosure is not limited to the embodiment and modified example. Even if it is not the embodiment and modified example, various modifications are possible according to the design, etc., as long as it does not deviate from the technical idea of ​​the present disclosure. In addition, the following embodiment (including modified examples) may be realized by appropriately combining them.

[0013] (1) Overview First, an overview of a linkage system 100 according to the present embodiment and a display system 2 included in the linkage system 100 will be described with reference to FIGS. 1, 2, and 4. FIG.

[0014] As shown in FIG. 1, the linkage system 100 includes a disaster prevention system 1 and a display system 2.

[0015] The disaster prevention system 1 is a system that is introduced into a facility 9 (see FIG. 2) and responds to abnormalities (disasters, etc.) in the facility 9. The facility 9 includes non-residential facilities such as stores, offices, business establishments, factories, buildings, schools, welfare facilities, or hospitals, as well as residential facilities such as detached houses, apartment buildings, or individual dwelling units in apartment buildings. Non-residential facilities also include theaters, movie theaters, public halls, amusement parks, complexes, restaurants, department stores, hotels, inns, kindergartens, libraries, museums, art galleries, underground shopping malls, stations, airports, and the like. Furthermore, the term "disaster" in this disclosure includes, for example, fires, gas leaks, earthquakes, flooding, and the like.

[0016] As shown in FIG. 1, the display system 2 includes an acquisition unit 252 and a display control unit 253.

[0017] The acquisition unit 252 acquires event information related to an abnormality detected by the disaster prevention system 1 installed in the facility 9.

[0018] Based on the event information acquired by the acquisition unit 252, the display control unit 253 causes the display unit 51 to display a display screen P1 showing a map Mp1 (see Figure 4) including the location where an abnormality detected by the disaster prevention system 1 has occurred and the current location of the display terminal 5 equipped with the display unit 51.

[0019] Here, the display terminal 5 is a communication terminal equipped with a display unit 51 such as a liquid crystal display, and includes, for example, a smartphone, a tablet terminal, a wearable terminal, a personal computer, digital signage, a car navigation system, etc. A user of the display terminal 5 (hereinafter, referred to as a terminal user) is, for example, an employee of a security company in charge of security for the facility 9, an inspection company in charge of inspection work for the disaster prevention system 1, an employee of a fire department, etc.

[0020] The facility 9 in this embodiment is a small-scale facility that is not required by the Fire Service Act to have a manager on-site at all times. That is, the facility 9 in this embodiment may be unmanned on holidays, late at night, etc.

[0021] In this embodiment, when an abnormality occurs in the facility 9, the display control unit 253 causes the display unit 51 to display a display screen P1 showing a map Mp1 including the location of the abnormality detected by the disaster prevention system 1 (specifically, a marker indicating the location of the abnormality) and the current location of the display terminal 5 (specifically, a marker indicating the current location of the display terminal 5). This allows the terminal user to head to the facility 9 to respond to the abnormality even if the facility 9 is unmanned, thereby reducing the possibility of a delay in responding to the abnormality.

[0022] (2) Composition In this embodiment, the linkage system 100 includes a plurality of (eg, three) disaster prevention systems 1 and a display system 2, as shown in FIG.

[0023] The three disaster prevention systems 1 are assumed to be installed in three different facilities 9. In the following description, when it is necessary to distinguish between the three disaster prevention systems 1, they will be referred to as disaster prevention systems 1A, 1B, and 1C. When it is necessary to distinguish between the three facilities 9, the facility 9 in which disaster prevention system 1A is installed will be referred to as facility 9A, the facility 9 in which disaster prevention system 1B is installed will be referred to as facility 9B, and the facility 9 in which disaster prevention system 1C is installed will be referred to as facility 9C. Furthermore, facilities 9A to 9C (see FIG. 14) are each assumed to be stores, and the administrative names of facilities 9A to 9C will be "first store," "second store," and "third store," respectively.

[0024] (2.1) Disaster prevention system Hereinafter, the configuration of the disaster prevention system 1 will be described in detail with reference to the drawings. In this embodiment, the "abnormality" that the disaster prevention system 1 deals with will be described as a "fire" as an example.

[0025] 1, the disaster prevention system 1 includes, for example, a plurality of sensors 3 and a receiver 4 capable of communicating with each of the plurality of sensors 3. Note that the number of sensors 3 included in the disaster prevention system 1 may be one.

[0026] (2.1.1) Sensor The multiple sensors 3 are installed on the ceiling of each of the multiple areas included in the facility 9. As an example, as shown in FIG. 2, a disaster prevention system 1A installed in a facility 9A, which is, for example, a one-story store, includes four sensors 3 (31-34) and one receiver 4. The sensors 31-34 are installed on the ceiling of the first area D1 to the fourth area D4 included in the facility 9A, respectively. Here, the management names of the sensors 31-34 are respectively "first sensor", "second sensor", "third sensor", and "fourth sensor". The management name of the single receiver 4 included in the disaster prevention system 1A is ("first receiver"). The management names of the first area D1 to the fourth area D4 are respectively "sales floor", "backyard", "men's restroom", and "women's restroom".

[0027] As shown in FIG. 1, each of the plurality of detectors 3 includes a temperature sensor 301, a smoke sensor 302, a notification unit 303, a communication unit 304, and a control unit 305.

[0028] The temperature sensor 301 includes a temperature-sensing element such as a thermistor, and outputs detection data corresponding to the surrounding temperature.

[0029] The smoke sensor 302 has, for example, a photoelectric smoke detector, and outputs detection data corresponding to the concentration of smoke in the surrounding area.

[0030] The alarm unit 303 issues an alarm by outputting at least one of light and sound.

[0031] The communication unit 304 is configured to be capable of communicating with the receiver 4. In this disclosure, "capable of communication" means that information can be exchanged directly or indirectly via a repeater or an internal network by an appropriate communication method such as wired communication or wireless communication.

[0032] The control unit 305 can be realized by, for example, a computer system including one or more processors (microprocessors) and one or more memories. In other words, the one or more processors execute one or more programs stored in one or more memories to function as the control unit 305. Here, the programs are pre-recorded in the memory of the control unit 305, but they may be provided via a telecommunications line such as the Internet, or recorded on a non-transitory recording medium such as a memory card.

[0033] The control unit 305 periodically acquires detection data from the temperature sensor 301 and the smoke sensor 302, and detects the presence or absence of a fire in the installation area of ​​the detector 3 based on the detection data of the temperature sensor 301 and the smoke sensor 302. Specifically, the control unit 305 compares the smoke concentration detected by the smoke sensor 302 with a predetermined concentration threshold based on the detection data input from the smoke sensor 302. If the smoke concentration is less than the concentration threshold, the control unit 305 determines that a fire has not occurred, and if the smoke concentration is equal to or greater than the concentration threshold, the control unit 305 determines that a fire has occurred. In addition, the control unit 305 performs a process of correcting the concentration threshold based on the detection data input from the temperature sensor 301. Based on the temperature detection data, the control unit 305 corrects the concentration threshold so that the smoke concentration threshold becomes smaller as the temperature increases, that is, so that the sensitivity becomes higher at higher temperatures. Note that the method by which the control unit 305 determines the presence or absence of a fire is not limited to the above method, and can be changed as appropriate.

[0034] When the control unit 305 determines that a fire has broken out, it controls the notification units 303 of the multiple sensors 3 installed in the facility 9 to perform a notification operation (issue an alarm). This makes it possible to notify people in the facility 9 of the occurrence of a fire.

[0035] Furthermore, the control unit 305 periodically acquires detection data from the temperature sensor 301 and the smoke sensor 302 , and causes the communication unit 304 to transmit the data to the receiver 4 .

[0036] (2.1.2) Receiver The receiver 4 is a receiving terminal that receives notifications regarding the occurrence of an abnormality (fire) from the multiple sensors 3.

[0037] Under normal circumstances, the receiver 4 operates by receiving power from an external power source, such as a commercial power source of 100V AC.

[0038] The receiver 4 is installed, for example, in a facility 9. As an example, in a facility 9A, it is assumed that the receiver 4 is installed in a second area D2, which is a backyard, as shown in FIG.

[0039] Note that the receiver 4 may be installed outside the facility 9 (for example, in a facility other than the facility 9) as long as it is capable of communicating with a plurality of sensors 3.

[0040] As shown in FIG. 1, the receiver 4 includes a first communication unit 41, a second communication unit 42, an operation unit 43, a power storage unit 44, a control unit 45, and a storage unit 46.

[0041] The first communication unit 41 is configured to be able to communicate with a plurality of sensors 3 .

[0042] The second communication unit 42 is configured to be able to communicate with a display system 2 (described later).

[0043] The power storage unit 44 is a standby power source for enabling the receiver 4 to operate in the event of a power outage of the commercial power source (external power source). The power storage unit 44 has a storage battery 441, such as a nickel-cadmium storage battery, an alkaline storage battery, a lithium-ion battery, or an all-solid-state battery, and a charge / discharge circuit 442 for controlling charging and discharging of the storage battery 441. The storage battery 441 is charged by the external power source via the charge / discharge circuit 442 under normal circumstances (when the external power source is not out of power).

[0044] The storage unit 46 is configured with a device selected from a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), and the like. The storage unit 46 stores detection data and the like acquired from the multiple sensors 3. The storage unit 46 also stores, for example, location information indicating the location of the facility 9 in which the disaster prevention system 1 is installed. The location information includes, for example, the address of the facility 9, or coordinate information indicating the location of the facility 9 acquired by a GPS (Global Positioning System), and the like. That is, in this embodiment, the storage unit 46 of the receiver 4 equipped in the disaster prevention systems 1A to 1C stores location information indicating the locations of the facilities 9A to 9C, respectively. Note that the location information indicating the location of the facility 9 may be held by the multiple sensors 3 equipped in the disaster prevention system 1. In this case, the location information indicating the location of the facility 9 may be appropriately transmitted from the sensor 3 to the receiver 4.

[0045] The storage unit 46 also stores area information indicating in which area of ​​the facility 9 each of the multiple sensors 3 is installed. As an example, the storage unit 46 of the receiver 4 included in the disaster prevention system 1A stores information indicating that the sensors 31-34 are installed in a first area D1-fourth area D4, respectively.

[0046] The operation unit 43 accepts operation inputs from a user of the disaster prevention system 1. The operation unit 43 includes, for example, a plurality of physical buttons. For example, when an alarm is issued by the detector 3 and it is a false alarm, the user of the disaster prevention system 1 can operate the operation unit 43 to store in the storage unit 46 the fact that an alarm (false alarm) has been issued by the detector 3. This operation also causes the storage unit 46 to accumulate and store alarm count information regarding the number of alarms issued by the detector 3.

[0047] The control unit 45 can be realized by, for example, a computer system including one or more processors (microprocessors) and one or more memories. In other words, the one or more processors execute one or more programs stored in one or more memories to function as the control unit 45. Here, the programs are pre-recorded in the memory of the control unit 45, but they may be provided via a telecommunications line such as the Internet or by being recorded on a non-transitory recording medium such as a memory card.

[0048] The control unit 45 has an acquisition unit 451, an output unit 452, an abnormality determination unit 453, a fault estimation unit 454, and a charge / discharge control unit 455. Note that these merely indicate functions realized by the control unit 45, and do not necessarily indicate actual configurations.

[0049] The acquisition unit 451 acquires, from each of the multiple sensors 3 installed within the facility 9, detection data of the temperature sensor 301 and the smoke sensor 302 provided in each of the multiple sensors 3.

[0050] The acquisition unit 451 periodically transmits a transmission request for detection data (detection data of the temperature sensor 301 and the smoke sensor 302) to the multiple detectors 3 via the first communication unit 41. The acquisition unit 451 acquires the detection data transmitted from each detector 3 in response to the transmission request via the first communication unit 41, and stores the data in the storage unit 46. That is, the storage unit 46 stores detection data for each of the multiple detectors 3. The storage unit 46 also stores communication information regarding the communication state between each of the multiple detectors 3 and the receiver 4.

[0051] Furthermore, if there is a sensor 3 from which detection data could not be acquired after transmitting a transmission request, the acquisition unit 451 determines that a communication error has occurred between the sensor 3 and the receiver 4. The acquisition unit 451 generates communication error information related to the communication error between the sensor 3 and the receiver 4, and stores it in the storage unit 46. The communication error information includes, for example, information previously stored in the storage unit 46 (such as location information indicating the location of the facility 9 and area information indicating the installation area of ​​the sensor 3 within the facility 9).

[0052] The abnormality determination unit 453 determines whether or not an abnormality (a fire in this embodiment) has occurred in the facility 9 based on the detection data of the temperature sensor 301 and the smoke sensor 302 acquired by the acquisition unit 451. The abnormality determination unit 453 determines whether or not a fire has occurred, for example, in a similar manner to that of the detector 3.

[0053] The charge / discharge control unit 455 controls the charge / discharge circuit 442 so that the current (charging current) supplied from the commercial power source to the storage battery 441 becomes a constant target value during normal operation. In addition, the charge / discharge control unit 455 cuts off the power supply path from the commercial power source to the storage battery 441 during a commercial power outage, and controls the charge / discharge circuit 442 so that the current discharged from the storage battery 441 (discharging current) becomes a constant target value.

[0054] Furthermore, during normal operation, the charge / discharge control unit 455 periodically (for example, once a day) cuts off the power supply path from the commercial power source to the storage battery 441, and measures the voltage (storage battery voltage) immediately after the start of discharging of the fully charged storage battery 441. Here, as the deterioration of the storage battery 441 progresses, the internal resistance of the storage battery 441 increases, and therefore the voltage (storage battery voltage) immediately after the start of discharging of the storage battery 441 decreases as the storage battery 441 deteriorates. In other words, the deterioration level of the storage battery 441 can be estimated from the storage battery voltage.

[0055] The charge / discharge control unit 455 stores the measured value of the storage battery voltage in the storage unit 46 as state information related to the deterioration state of the storage battery 441.

[0056] Furthermore, when the storage battery voltage falls below a preset predetermined voltage, the charge / discharge control unit 455 generates storage battery error information related to deterioration of the storage battery 441 and stores it in the storage unit 46. The storage battery error information includes, for example, location information indicating the location of the facility 9, the value of the storage battery voltage, the date and time when the storage battery voltage fell below the predetermined voltage, and the like. Note that in this embodiment, the rated voltage of the storage battery 441 is, for example, 24 V, and the predetermined voltage is 20.4 V, which is 85% of the rated voltage. In other words, the charge / discharge control unit 455 generates storage battery error information when the storage battery voltage of the storage battery 441 falls below 20.4 V.

[0057] When the number of times the same detector 3 has activated an alarm exceeds a predetermined number (e.g., 10 times) in a predetermined period (e.g., one month) based on the information on the number of times the detector 3 has activated an alarm stored in the storage unit 46, the failure estimation unit 454 generates detector error information regarding the possibility of a detector 3 malfunction and stores it in the storage unit 46. The detector error information includes, for example, location information indicating the location of the facility 9, area information indicating the installation area within the facility 9 of the detector 3 that has activated an alarm more than the predetermined number of times, and the like.

[0058] When the abnormality determination unit 453 determines that an abnormality (fire) has occurred in the facility 9, the output unit 452 transmits event information indicating that an abnormality (fire) has occurred in the facility 9 to the display system 2 (described later) via the second communication unit 42. Here, the event information includes location information indicating the location of the facility 9 where the fire has occurred. That is, in this embodiment, the event information includes information indicating in which facility 9 of facilities 9A to 9C the fire has occurred.

[0059] Furthermore, the output unit 452 transmits error information related to an error that has occurred in the disaster prevention system 1 to the display system 2 via the second communication unit 42. Here, the error information includes the above-mentioned communication error information related to a communication error between the sensor 3 and the receiver 4, storage battery error information related to deterioration of the storage battery 441, and sensor error information related to a possibility of a malfunction of the sensor 3. Note that in this embodiment, the output unit 452 transmits each piece of error information to the display system 2 immediately after each piece of error information is generated in the disaster prevention system 1. Note that the transmission of each piece of error information to the display system 2 is not limited to immediately after each piece of error information is generated, and may be performed at the timing when a transmission instruction is received from the display system 2.

[0060] (2.2) Display System The configuration of the display system 2 will be described in detail below with reference to the drawings.

[0061] The display system 2 is, for example, a server installed outside the facility 9. Note that the display system 2 is preferably installed in a remote location away from the facility 9.

[0062] As shown in FIG. 1, the display system 2 includes a third communication unit 21, a fourth communication unit 22, a fifth communication unit 23, a storage unit 24, and a control unit 25.

[0063] The third communication unit 21 is configured to be able to communicate with each of the receivers 4 of the multiple disaster prevention systems 1 (1A to 1C).

[0064] The fourth communication unit 22 is configured to be able to communicate with a display terminal 5, which will be described later.

[0065] The fifth communication unit 23 is configured to be able to communicate with the external server 6. The external server 6 is, for example, a server managed by a company that provides information related to maps.

[0066] The storage unit 24 is configured with a device selected from a ROM, a RAM, an EEPROM, etc. The storage unit 24 stores information acquired from the receiver 4, the display terminal 5, and the external server 6, etc.

[0067] The control unit 25 can be realized by, for example, a computer system including one or more processors (microprocessors) and one or more memories. That is, the one or more processors execute one or more programs stored in one or more memories to function as the control unit 25. Here, the programs are pre-recorded in the memory of the control unit 25, but they may be provided via a telecommunications line such as the Internet or by being recorded on a non-transitory recording medium such as a memory card.

[0068] The control unit 25 has a request unit 251, an acquisition unit 252, and a display control unit 253. Furthermore, the display control unit 253 has a map generation unit 254, a user determination unit 255, a route generation unit 256, a message generation unit 257, an information image generation unit 258, a first output unit 259, a second output unit 260, and a third output unit 261. Note that these merely indicate functions realized by the control unit 25, and do not necessarily indicate actual configurations.

[0069] The request unit 251 transmits a request signal requesting transmission of information related to the disaster prevention system 1 installed in the facility 9 to the disaster prevention system 1 (receiver 4) via the third communication unit 21. In this embodiment, the request unit 251 transmits the request signal to at least one of the disaster prevention systems 1A to 1C.

[0070] Here, the request signal includes an existing information request signal and a new information request signal.

[0071] The existing information request signal is a request signal for requesting transmission of maintenance information related to the maintenance of the disaster prevention system 1, which is stored in advance in the disaster prevention system 1 as information related to the disaster prevention system 1.

[0072] The new information request signal is a request signal that requests the disaster prevention system 1 to generate maintenance information related to the maintenance of the disaster prevention system 1 and to transmit the maintenance information generated by the disaster prevention system 1 as information related to the disaster prevention system 1.

[0073] In this embodiment, the maintenance information regarding the maintenance of the disaster prevention system 1 includes, for example, status information regarding the degradation state of the storage battery 441 (storage battery voltage of the storage battery 441). The maintenance information also includes communication information regarding the communication state between each of the multiple sensors 3 and the receiver 4. Furthermore, the maintenance information includes alarm count information regarding the number of alarms of the sensor 3 in a predetermined period. Note that the maintenance information is not limited to the above information, and may include information regarding a memory area inside the receiver 4, a status regarding a failure of a board on which electronic components of the receiver 4 are mounted, information regarding a failure of the temperature sensor 301 and the smoke sensor 302 of the sensor 3, and information regarding a failure of a board on which electronic components of the sensor 3 are mounted.

[0074] The acquisition unit 252 acquires event information related to an abnormality detected by the disaster prevention system 1 via the third communication unit 21. In this embodiment, the event information is information indicating that a fire has occurred in the facility 9. As described above, the event information includes location information indicating the location of the facility 9 where the fire has occurred. Acquisition of the event information by the acquisition unit 252 will be described in detail in "(3.1) Example of operation when an abnormality occurs."

[0075] The acquisition unit 252 also acquires error information related to an error that has occurred in the disaster prevention system 1 via the third communication unit 21. As described above, the error information includes communication error information related to a communication error between the sensor 3 and the receiver 4, storage battery error information related to deterioration of the storage battery 441, and sensor error information related to a possible malfunction of the sensor 3. As described above, each of the communication error information, storage battery error information, and sensor error information includes location information indicating the location of the facility 9. Acquisition of error information by the acquisition unit 252 will be described in detail in "(3.2) Example of Operation When an Error Occurs."

[0076] Furthermore, the acquisition unit 252 acquires information about the disaster prevention system 1 transmitted by the disaster prevention system 1 in response to a request signal via the third communication unit 21. Acquisition of information about the disaster prevention system 1 by the acquisition unit 252 will be described in detail in "(3.3) Example of operation when acquiring information".

[0077] The acquisition unit 252 acquires information on the current location of the display terminal 5 from the display terminal 5 via the fourth communication unit 22. The acquisition unit 252 also acquires attribute information of the terminal user from the display terminal 5. Here, the attribute information of the terminal user is information indicating whether the terminal user is a first user (a security company employee in charge of security at the facility 9, an inspection company in charge of inspection work for the disaster prevention system 1, a fire department employee, etc.) who needs to head to the facility 9 if an abnormality such as a fire occurs at the facility 9, or a second user (a general public, etc.) who should not approach the facility 9 if an abnormality such as a fire occurs at the facility 9.

[0078] The acquisition unit 252 acquires map information of the surroundings of the facility 9 from the external server 6 via the fifth communication unit 23. Note that the exchange of information between the display system 2 and the external server 6 is realized by, for example, an API (Application Programming Interface) implemented in the external server 6.

[0079] The map generation unit 254 generates a map including a marker indicating the position of the facility 9 where the fire occurred and a marker indicating the current position of the display terminal 5 based on the event information acquired by the acquisition unit 252, information on the current position of the display terminal 5, and map information around the facility 9.

[0080] Furthermore, the map generating unit 254 generates a map including a marker indicating the position related to the source of the error (for example, the position of the facility 9 in which the disaster prevention system 1 in which the error occurred is installed) and a marker indicating the current position of the display terminal 5, based on the error information acquired by the acquiring unit 252, the information on the current position of the display terminal 5, and map information of the periphery of the facility 9. Note that the position related to the source of the error may be, for example, the position of the area in the facility 9 in which the detector 3 from which the error occurred is installed if the source of the error is the detector 3, or may be the position of the area in the facility 9 in which the receiver 4 is installed if the source of the error is the receiver 4.

[0081] The user determination unit 255 determines whether the terminal user is the first user or the second user, based on the attribute information of the terminal user acquired by the acquisition unit 252 from the display terminal 5. As described above, the first user is a user who needs to head to the facility 9 when an abnormality such as a fire occurs in the facility 9, and the second user is a user who should not approach the facility 9 when an abnormality such as a fire occurs in the facility 9. Note that, among the first users, for example, an inspection company in charge of inspecting the disaster prevention system 1 needs to head to the facility 9 even when an error occurs in the disaster prevention system 1 installed in the facility 9.

[0082] The route generation unit 256 generates at least one of a first route from the current position of the display terminal 5 to the position of the facility 9 where the fire has occurred, and a second route from the current position of the display terminal 5 to a specified position different from the position of the facility 9 where the fire has occurred.

[0083] Furthermore, the route generating unit 256 generates a third route from the current position of the display terminal 5 to a position related to the source of the error (for example, the position of the facility 9 in which the disaster prevention system 1 where the error occurred is installed).

[0084] The message generating unit 257 generates a message regarding event information, which is information indicating that a fire has occurred.

[0085] The message regarding the event information includes either a guidance message M1 (see FIG. 5) that guides the terminal user to the location of the facility 9, or an avoidance message M2 (see FIG. 7) that prevents the terminal user from approaching the location of the facility 9.

[0086] Furthermore, the message generating unit 257 generates an error message M3 (see FIG. 11) indicating the content of the error based on error information that is information indicating that an error has occurred in the disaster prevention system 1.

[0087] The information image generating unit 258 generates an information image in which maintenance information relating to the maintenance of the disaster prevention system 1 is visualized.

[0088] The first output unit 259 causes the display unit 51 of the display terminal 5 to display a display screen showing a map that the map generation unit 254 generated based on the event information, the information on the current position of the display terminal 5, and map information about the periphery of the facility 9.

[0089] Furthermore, the first output unit 259 causes the display unit 51 to display a message related to the event information. More specifically, when the user determination unit 255 determines that the terminal user is the first user, the first output unit 259 causes the display unit 51 to display a guidance message M1. When the user determination unit 255 determines that the terminal user is the second user, the first output unit 259 causes the display unit 51 to display an avoidance message M2. That is, the first output unit 259 determines the message to be displayed on the display unit 51 to be either the guidance message M1 or the avoidance message M2, based on the attribute information of the terminal user.

[0090] The second output unit 260 causes the display unit 51 to display a display screen showing a map generated by the map generation unit 254 based on the error information, the information on the current position of the display terminal 5, and map information of the periphery of the facility 9. In addition, the second output unit 260 causes the display unit 51 to display an error message M3.

[0091] In addition, the second output unit 260 causes the display unit 51 to display a display screen showing a map including a third route from the current location of the display terminal 5 to the location related to the source of the error (for example, the location of the facility 9 in which the disaster prevention system 1 where the error occurred is installed).

[0092] The third output unit 261 causes the display unit 51 to display a display screen including an image in which the information of the disaster prevention system 1 is visualized.

[0093] (2.3) Display Terminal The display terminal 5 is a communication terminal used outside the facility 9. Specifically, the display terminal 5 includes communication terminals such as a smartphone, a tablet terminal, a wearable terminal, a personal computer, digital signage, and a car navigation system.

[0094] In this embodiment, a dedicated application software (program) is installed on the communication terminal to enable the exchange of information with the display system 2 and the display of information transmitted from the display system 2, so that the communication terminal functions as the display terminal 5.

[0095] As shown in FIG. 1, the display terminal 5 includes a display unit 51, a communication unit 52, an operation unit 53, a storage unit 54, a position detection unit 55, and a control unit 56.

[0096] The communication unit 52 is configured to be able to communicate with the display system 2.

[0097] The display unit 51 is a display device, such as a liquid crystal display, capable of displaying various pieces of information acquired by the communication unit 52 from the display system 2.

[0098] The operation unit 53 accepts operation input from the terminal user. The operation unit 53 is configured as, for example, a touch panel that detects a touch operation on the display screen displayed on the display unit 51. This allows the worker to perform an operation input to the display terminal 5 by performing a touch operation on the display screen of the display unit 51. For example, the terminal user can register his / her own attribute information (whether the terminal user is a first user or a second user) in advance by operating the operation unit 53.

[0099] The storage unit 54 is configured with a device selected from a ROM, a RAM, an EEPROM, etc. The storage unit 54 stores information acquired by the communication unit 52 from the display system 2, etc.

[0100] The position detection unit 55 has, for example, a GPS receiver that detects the current position of the display terminal 5. The position detection unit 55 receives radio waves transmitted from a GPS satellite and detects the current position of the display terminal 5. Information on the current position of the display terminal 5 detected by the position detection unit 55 is transmitted to the display system 2 as appropriate.

[0101] The control unit 56 can be realized by, for example, a computer system including one or more processors (microprocessors) and one or more memories. In other words, the one or more processors execute one or more programs stored in one or more memories to function as the control unit 56. Here, the programs are pre-recorded in the memory of the control unit 56, but they may be provided via a telecommunications line such as the Internet or by being recorded on a non-transitory recording medium such as a memory card.

[0102] The control unit 56 controls each unit of the display terminal 5 (the display unit 51, the communication unit 52, the operation unit 53, the storage unit 54, and the position detection unit 55).

[0103] (3) Example of the operation of the linked system An example of the operation of the linkage system 100 will be described below with reference to Figures 1 to 18. Here, the flowcharts shown in Figures 3, 9, and 13 merely show an example of the operation of the linkage system 100 according to this embodiment, and the order of the processes may be changed as appropriate, and processes may be added or omitted as appropriate.

[0104] (3.1) Example of operation when an abnormality occurs The operation of the linkage system 100 in the case where an abnormality (fire) occurs, for example, in the facility 9A among the facilities 9A to 9C, will be described below with reference to the flowchart of FIG. 3 and other figures.

[0105] When a fire breaks out in the facility 9A (step S1), the output unit 452 of the receiver 4 included in the disaster prevention system 1A transmits to the display system 2 event information including the position information of the facility 9A.

[0106] When the acquisition unit 252 of the display system 2 acquires the event information from the disaster prevention system 1A (step S2), it acquires information on the current location of the display terminal 5 from the display terminal 5 (step S3). As an example, the display terminal 5 is a tablet terminal carried by the terminal user.

[0107] The acquisition unit 252 acquires, for example, information on the current position of the display terminal 5 that is present within a predetermined range around the facility 9A. Note that the predetermined range from which the acquisition unit 252 acquires information on the current position of the display terminal 5 can be changed by, for example, an administrator of the display system 2.

[0108] The acquisition unit 252 acquires attribute information of the terminal user that has been registered in advance by the terminal user together with information on the current location of the display terminal 5 (step S4).

[0109] Furthermore, the acquisition unit 252 acquires map information of the surroundings of the facility 9A from the external server 6 (step S5). Note that the range of the map information acquired by the acquisition unit 252 from the external server 6 can be changed by, for example, an administrator of the display system 2.

[0110] Next, the map generation unit 254 generates a map Mp1 including a marker Mk1 indicating the position of the facility 9A, which is the location of the fire, and a marker Mk2 indicating the current position of the display terminal 5, based on the event information acquired by the acquisition unit 252, information on the current position of the display terminal 5, and map information around the facility 9A.

[0111] 4, the first output unit 259 causes the display unit 51 of the display terminal 5 to display a display screen P1 indicating the map Mp1 generated by the map generating unit 254 (step S6). Note that in the map Mp1, a marker Mk3 indicating that a fire has broken out is displayed superimposed on the marker Mk1 indicating the position of the facility 9A.

[0112] Next, the user determination unit 255 determines whether the terminal user is the first user or the second user based on the attribute information of the terminal user acquired by the acquisition unit 252 (step S7). Note that the determination of the terminal user by the user determination unit 255 may be performed before the map generation unit 254 generates the map Mp1.

[0113] When the user determination unit 255 determines that the terminal user is the first user (step S7: Yes), the message generation unit 257 generates a guidance message M1 that guides the terminal user to the location of the facility 9A.

[0114] When a predetermined time has elapsed since the display screen P1 showing the map Mp1 was displayed on the display unit 51, the first output unit 259 causes the display unit 51 to display the guidance message M1 superimposed on the map Mp1 as shown in Fig. 5 (step S8). Note that the first output unit 259 may cause the display unit 51 to display the guidance message M1 when the terminal user taps the display screen P1. Also, the method of displaying the guidance message M1 is not limited to the method of superimposing the guidance message M1 on the map Mp1, and the guidance message M1 may be displayed adjacent to the map Mp1.

[0115] The guidance message M1 is, for example, a character string such as "A fire has broken out at the first store. Please head to the scene." Note that the guidance message M1 may include a character string (such as an address) indicating the location of the facility 9A.

[0116] Furthermore, when the user determination unit 255 determines that the terminal user is the first user (step S7: Yes), the route generation unit 256 generates a first route R1 from the current position of the display terminal 5 to the position of the facility 9A. Note that the first route R1 is preferably the shortest route from the current position of the display terminal 5 to the position of the facility 9A.

[0117] Furthermore, the route generation unit 256 estimates the time required for the terminal user to move on the first route R1 from the current location to the location of the facility 9A. Specifically, the route generation unit 256 estimates the time required based on the distance of the first route R1, the movement speed of the terminal user, and traffic information on the first route R1 (presence or absence of congestion, etc.). Note that the distance of the first route R1 and the traffic information on the first route R1 are acquired by the acquisition unit 252 from the external server 6, for example. Also, the movement speed of the terminal user may be calculated from, for example, the amount of change in the current location of the display terminal 5 acquired from the position detection unit 55 of the display terminal 5.

[0118] For example, when a predetermined time has elapsed since the guidance message M1 was displayed on the display unit 51, the first output unit 259 causes the display unit 51 to display a display screen P2 showing a map Mp2 including the first route R1, as shown in Fig. 6 (step S9). Note that the first output unit 259 may cause the display unit 51 to display the display screen P2 when the terminal user taps on the guidance message M1 displayed on the display unit 51.

[0119] At this time, the first output unit 259 causes the display unit 51 to display information related to the required time estimated by the route generation unit 256. Specifically, the first output unit 259 causes the image Im1 including the information related to the required time estimated by the route generation unit 256 to be superimposed on, for example, the map Mp2 and displayed. As an example, the image Im1 includes a character string "Estimated required time: 5 minutes". Note that the image Im1 may include symbols, figures, and the like. In addition, the method of displaying the image Im1 including the information related to the required time is not limited to the method of superimposing the image Im1 on the map Mp2, and the image Im1 may be displayed adjacent to the map Mp2.

[0120] These operations of the linkage system 100 enable the terminal user, who is the first user, to quickly head to the facility 9A where the fire has broken out, thereby reducing the possibility of a delay in responding to the fire.

[0121] On the other hand, if the user determination unit 255 determines that the terminal user is the second user (step S7: No), the message generation unit 257 generates an avoidance message M2 that prevents the terminal user from approaching the location of the facility 9A.

[0122] When a predetermined time has elapsed since the display screen P1 showing the map Mp1 was displayed on the display unit 51, the first output unit 259 causes the display unit 51 to display the avoidance message M2 superimposed on the map Mp1 as shown in FIG. 7 (step S10). The avoidance message M2 is, for example, a character string such as "A fire has broken out at the first store. Please leave the scene." Note that the first output unit 259 may cause the display unit 51 to display the avoidance message M2 when the terminal user taps on the display screen P1 showing the map Mp1. In addition, the method of displaying the avoidance message M2 is not limited to the method of superimposing the avoidance message M2 on the map Mp1, and the avoidance message M2 may be displayed adjacent to the map Mp1.

[0123] Furthermore, when the user determination unit 255 determines that the terminal user is the second user (step S7: No), the route generation unit 256 generates a second route R2 from the current position of the display terminal 5 to a predetermined position different from the position of the facility 9A. In other words, the second route R2 is a route that does not include the position of the facility 9. Here, the predetermined position different from the position of the facility 9A may be, for example, a destination registered in advance in the display terminal 5 by the terminal user who is the second user, or may be a destination (home, school, workplace, etc.) estimated from the movement history of the terminal user who is the second user. Note that the information on the predetermined position may be acquired from the display terminal 5 by the acquisition unit 252 when the route generation unit 256 generates the second route R2.

[0124] When a predetermined time has elapsed since the first output unit 259 caused the display unit 51 to display the avoidance message M2, the first output unit 259 causes the display unit 51 to display a display screen P3 showing a map Mp3 including the second route R2, as shown in Fig. 8 (step S11). The map Mp3 includes a marker Mk4 indicating a predetermined position different from the position of the facility 9A, in addition to the markers Mk1 to Mk3. Note that the first output unit 259 may cause the display unit 51 to display the display screen P3 when the terminal user taps the avoidance message M2 displayed on the display unit 51.

[0125] These operations of the linkage system 100 enable the terminal user, who is the second user, to avoid approaching the facility 9A where the fire has broken out.

[0126] (3.2) Example of operation when an error occurs The operation of the linked system 100 when an error occurs in the disaster prevention system 1A installed in, for example, facility 9A among the facilities 9A to 9C will be described below with reference to the flowchart in Fig. 9 etc. More specifically, in this operation example, it is assumed that the sensor 33 installed in the third area D3 (men's restroom) of facility 9A breaks down and a communication error occurs between the sensor 33 and the receiver 4.

[0127] When a communication error occurs between the sensor 33 and the receiver 4 (step S11), the output unit 452 of the receiver 4 included in the disaster prevention system 1A transmits error information (communication error information) to the display system 2. Here, the communication error information includes information on the location of the facility 9A and information on the area in the facility 9A where the sensor 33 is installed (the third area D3 which is the men's restroom).

[0128] When the acquisition unit 252 of the display system 2 acquires the error information from the disaster prevention system 1A (step S12), it acquires information on the current position of the display terminal 5 from the display terminal 5 (step S13). Here, the acquisition unit 252 acquires information on the current position of the display terminal 5 that is present within a predetermined range around the facility 9A, for example. Note that the predetermined range from which the acquisition unit 252 acquires information on the current position of the display terminal 5 can be changed by, for example, an administrator of the display system 2.

[0129] The acquisition unit 252 acquires attribute information of the terminal user of the display terminal 5 (step S14).

[0130] The user determination unit 255 determines whether the terminal user is the first user or the second user based on the attribute information of the terminal user acquired by the acquisition unit 252 (step S15).

[0131] When the user determination unit 255 determines that the terminal user is the first user (step S15: Yes), the acquisition unit 252 acquires map information of the surroundings of the facility 9A from the external server 6 (step S16). When the user determination unit 255 determines that the terminal user is the second user (step S15: No), the display system 2 ends the process.

[0132] The map generation unit 254 generates a map Mp4 including a marker Mk1 indicating the position of the facility 9A in which the disaster prevention system 1A in which the error occurred is installed and a marker Mk2 indicating the current position of the display terminal 5, based on the error information acquired by the acquisition unit 252, information on the current position of the display terminal 5, and map information around the facility 9A.

[0133] 10, the second output unit 260 causes the display unit 51 of the display terminal 5 to display a display screen P4 indicating the map Mp4 generated by the map generation unit 254 (step S17). Note that in the map Mp4 displayed on the display screen P4, a marker Mk5 indicating that an error has occurred is superimposed on the marker Mk1 indicating the position of the facility 9A.

[0134] Next, the message generating unit 257 generates an error message M3 indicating the contents of the error based on the error information. When a predetermined time has elapsed since the display screen P4 showing the map Mp4 was displayed on the display unit 51, the second output unit 260 causes the display unit 51 to display the error message M3 superimposed on the map Mp4 as shown in FIG. 11 (step S18). Note that the second output unit 260 may cause the display unit 51 to display the error message M3 when the terminal user taps on the display screen P4 showing the map Mp4. Also, the method of displaying the error message M3 is not limited to the method of superimposing it on the map Mp4, and the error message M3 may be displayed adjacent to the map Mp4.

[0135] As shown in FIG. 11, the error message M3 includes the first information A1 to the fifth information A5. The first information A1 is a character string including the type of error ("Error type: detector communication error"). The second information A2 is a character string including the name of the facility 9 (9A) in which the disaster prevention system 1 (1A) in which the error occurred is installed ("Facility in which the error occurred: First Store"). The third information A3 is a character string including the name of the area in which the detector 3 (33) in which the error occurred is installed in the facility 9A ("Location of the error: Men's restroom"). The fourth information A4 is a character string including the name of the detector 3 (33) in which the error occurred (Detector name: Third detector).

[0136] The fifth information A5 is guide information related to dealing with errors. Here, the guide information includes information indicating a link destination to data of the instruction manual of at least one of the detector 3 and the receiver 4. In this operation example, the guide information is a character string ("instruction manual link") indicating a link destination to data of the instruction manual of the detector 33 ("third detector"). Note that the character string indicating the link destination to the data of the instruction manual is highlighted, for example, by displaying an underline, to indicate that a tap operation is possible by the terminal user. Note that the method of highlighting to indicate that a tap operation is possible by the terminal user is not limited to displaying an underline, and may be a change in color, format, or the like.

[0137] That is, the error message M3 further includes guide information related to how to deal with the error. In other words, the message generating unit 257 generates guide information related to how to deal with the error based on the error information, and the second output unit 260 causes the display unit 51 to display the guide information.

[0138] The terminal user can access the data of the instruction manual for the detector 33 by tapping the portion on the display unit 51 where the guide information (fifth information A5) is displayed. The data of the instruction manual for the detector 33 may be stored in the storage unit 24 of the display system 2, or may be stored in an external server. When an error occurs in the receiver 4 (deterioration of the storage battery 441, etc.), the guide information may be information indicating a link destination to the data of the instruction manual for the receiver 4. When an error occurs in both the detector 3 and the receiver 4, the guide information may be information indicating a link destination to the data of the instruction manual for both the detector 3 and the receiver 4.

[0139] Furthermore, if the user determination unit 255 determines that the terminal user is the first user (step S15: Yes), the route generation unit 256 generates a third route R3 from the current position of the display terminal 5 to the position of the facility 9A.

[0140] For example, when a predetermined time has elapsed since the second output unit 260 displayed the error message M3 on the display unit 51, the second output unit 260 causes the display unit 51 to display a display screen P5 showing a map Mp5 including the third route R3, as shown in Fig. 12 (step S19). Note that the second output unit 260 may cause the display unit 51 to display the display screen P5 when the terminal user taps the error message M3 displayed on the display unit 51.

[0141] These operations of the linkage system 100 allow the terminal user, who is the first user, to quickly head to facility 9A when an error occurs even if the user is away from the location where the error occurred (facility 9A), thereby reducing the possibility of a delay in responding to the error. Also, the terminal user can know the content of the error in advance from the error message M3 and can head to facility 9A carrying items (substitute parts, etc.) necessary for responding to the error, thereby reducing the number of visits to facility 9A.

[0142] (3.3) Example of operation when acquiring information Below, we will explain the operation of the collaboration system 100 when, for example, a first user, that is, a user (terminal user) of the display terminal 5, obtains information about the disaster prevention system 1A installed in the facility 9A among the disaster prevention systems 1A to 1C, with reference to the flowchart in Figure 13, etc.

[0143] First, the third output unit 261 receives a predetermined operation of the operation unit 53 of the display terminal 5 by the terminal user, and causes the display unit 51 to display the facility selection screen P6 (see FIG. 14) (step S21). In this operation example, it is assumed that the display terminal 5 is a tablet terminal carried by the terminal user.

[0144] The facility selection screen P6 is a screen that displays, for example, a map Mp6 that includes markers Mk6 and Mk7 indicating the positions of facilities 9B and 9C, respectively, in addition to a marker Mk1 indicating the position of the facility 9A.

[0145] On the map Mp6, markers Mk8 to Mk10, which indicate that the markers Mk1, Mk6, and Mk7 can be selected by a tap operation, are displayed superimposed on the markers Mk1, Mk6, and Mk7. The map Mp6 may be stored in advance in the storage unit 24 of the display system 2, or may be generated by the map generation unit 254 based on location information indicating the locations of the facilities 9A to 9C transmitted from the receivers 4 of the disaster prevention systems 1A to 1C. The facility selection screen P6 is not limited to a screen including the map Mp6, and may display the names of the facilities 9A to 9C ("First Store", "Second Store", "Third Store") in a state in which they can be selected (by a tap operation) by the terminal user.

[0146] When the terminal user performs a tap operation on the marker Mk1 indicating the position of the facility 9A on the map Mp6, for example, the facility 9A is selected (step S22).

[0147] When the facility 9A is selected, the third output unit 261 causes the display unit 51 to display an equipment selection image Im2 (see FIG. 15) for selecting equipment to be provided in the disaster prevention system 1A to be installed in the facility 9A, superimposed on the map Mp6.

[0148] The equipment selection image Im2 is an image including, for example, the name of the facility 9A (first store), the names of the sensors 31-34 included in the disaster prevention system 1A ("first sensor", "second sensor", "third sensor" and "fourth sensor"), and the name of the receiver 4 included in the disaster prevention system 1A ("first receiver"). The names of the sensors 31-34 included in the disaster prevention system 1A and the name of the receiver 4 included in the disaster prevention system 1A are highlighted by, for example, displaying an underline to indicate that a tap operation is possible by the terminal user. The highlighting method for indicating that a tap operation is possible by the terminal user is not limited to displaying an underline, and may be a change in color, format, or the like. The equipment selection image Im2 may also include symbols, figures, and the like indicating the sensors 31-34 and the receiver 4 included in the disaster prevention system 1A.

[0149] The facility selection image Im2 is stored in advance in the storage unit 24 of the display system 2, for example, and is displayed on the display unit 51 by the third output unit 261.

[0150] In other words, when the terminal user taps the marker Mk1 indicating the position of the facility 9A on the map Mp6, the third output unit 261 causes the display unit 51 to display a display screen (facility selection screen) P7 including the facility selection image Im2 and the map Mp6, as shown in FIG. 15 (step S23).

[0151] For example, when the terminal user wants to know status information (maintenance information) related to the degradation state of the storage battery 441 of the receiver 4, the terminal user taps on a portion of the facility selection image Im2 displaying the name of the receiver 4 ("first receiver"). Note that when the terminal user wants to know communication information related to the communication state between the receiver 4 and any of the sensors 31 to 34, the terminal user can tap on any of the portions displaying the "first sensor", "second sensor", "third sensor" and "fourth sensor".

[0152] When the terminal user taps on the portion of the facility selection screen P7 where the name of the receiver 4 is displayed, the receiver 4 is selected (step S24).

[0153] When the receiver 4 is selected, the third output unit 261 causes the display unit 51 to display an information selection image Im3 (see FIG. 16) superimposed on the map Mp6.

[0154] The information selection image Im3 is an image for selecting whether to acquire existing information, which is maintenance information pre-stored in the disaster prevention system 1 (in this case, status information regarding the degraded state of the storage battery 441), or new information, which is maintenance information newly generated by the disaster prevention system 1 (status information regarding the degraded state of the storage battery 441).

[0155] The information selection image Im3 includes, for example, the name of the facility 9A (first store), the name of the receiver 4 ("first receiver"), a character string indicating the maintenance information to be acquired ("storage battery status information"), a character string for selecting acquisition of existing information ("acquire existing information"), and a character string for selecting acquisition of new information ("acquire new information"). Note that the character string for selecting acquisition of existing information and the character string for selecting acquisition of new information are highlighted by, for example, displaying an underline to indicate that a tap operation is possible by the terminal user. Note that the method of highlighting to indicate that a tap operation is possible by the terminal user is not limited to displaying an underline, and may be a change in color, format, or the like.

[0156] The information selection image Im3 is stored in advance in the storage unit 24 of the display system 2, for example, and is displayed on the display unit 51 by the third output unit 261.

[0157] In other words, when the terminal user taps the portion of the equipment selection screen P7 where the name of the receiver 4 is displayed, the display unit 51 displays a display screen (information selection screen) P8 including an information selection image Im3 and a map Mp6 on the display unit 51, as shown in FIG. 16 (step S25).

[0158] Here, if the terminal user wishes to obtain existing status information, for example, the terminal user taps on a portion of the information selection image Im3 where the character string "Obtain existing information" is displayed.

[0159] When the terminal user taps on the portion where the character string "Acquire existing information" is displayed (step S26: Yes), the request unit 251 of the display system 2 transmits an existing information request signal to the receiver 4 provided in the disaster prevention system 1A, requesting transmission of status information related to the degradation status of the storage battery 441 pre-stored in the disaster prevention system 1A (step S27). If the terminal user taps on, for example, "first sensor" in the facility selection image Im2, the request unit 251 transmits to the receiver 4 an existing information request signal requesting transmission of communication information related to the communication status between the sensor 31 pre-stored in the disaster prevention system 1A and the receiver 4.

[0160] When the second communication unit 42 of the receiver 4 receives the existing information request signal, the output unit 452 of the receiver 4 transmits the existing state information related to the degradation state of the storage battery 441 stored in the memory unit 46 to the display system 2. Here, the existing state information includes, for example, the value of the storage battery voltage of the storage battery 441 most recently measured by the charge / discharge control unit 455.

[0161] When the acquisition unit 252 of the display system 2 acquires the existing status information (step S28), the information image generation unit 258 of the display system 2 generates an existing information image Im4 that visualizes the existing status information based on the existing status information, and the third output unit 261 superimposes the existing information image Im4 (see Figure 17) on the map Mp6 and displays it on the display unit 51.

[0162] The existing information image Im4 includes, as an example, the name of the facility 9A (first store), the name of the receiver 4 ("first receiver"), a character string representing a display of existing information ("existing information"), a character string indicating the value of the storage battery voltage of the storage battery 441 most recently measured by the charge / discharge control unit 455 ("storage battery voltage: 21V"), and a character string indicating the deterioration state of the storage battery 441 ("storage battery state: normal"). Note that, here, it is assumed that the storage battery voltage of the storage battery 441 most recently measured is 21V, which is higher than the predetermined value of 20.4V.

[0163] In other words, when the acquisition unit 252 of the display system 2 acquires the existing status information, the third output unit 261 causes the display unit 51 to display a display screen (existing information display screen) P9 including an existing information image Im4 and a map Mp6 including a marker Mk1 indicating the position of the facility 9A, as shown in FIG. 17 (step S29).

[0164] These operations of the linkage system 100 enable the terminal user to obtain information about the disaster prevention system 1 at a location away from the facility 9 in which the disaster prevention system 1 is installed.

[0165] On the other hand, when the terminal user wishes to obtain new status information, the terminal user taps on a portion of the information selection image Im3 where the character string "Obtain new information" is displayed.

[0166] When the terminal user taps the portion where the character string "Get new information" is displayed (step S26: No), the request unit 251 generates status information related to the degradation state of the storage battery 441 and transmits a new information request signal to the receiver 4 requesting transmission of the generated status information (step S30). Note that, if the terminal user taps, for example, "first detector" in the facility selection image Im2, the request unit 251 generates communication information related to the communication state between the detector 31 and the receiver 4 and transmits a new information request signal to the receiver 4 requesting transmission of the generated communication information.

[0167] When the second communication unit 42 of the receiver 4 receives the new information request signal, the charge / discharge control unit 455 cuts off the power supply path from the commercial power source to the storage battery 441, and measures the storage battery voltage immediately after the storage battery 441 starts discharging.

[0168] Here, it is assumed that the battery voltage of the storage battery 441 is, for example, 20 V, which is lower than the predetermined voltage of 20.4 V. In this case, the charge / discharge control unit 455 generates battery error information related to the deterioration of the storage battery 441. As described above, the battery error information includes information on the value of the storage battery voltage (20 V) of the storage battery 441. In other words, the battery error information transmitted in response to a new information request signal includes new status information (a newly measured value of the storage battery voltage).

[0169] Next, the output unit 452 of the receiver 4 transmits the generated storage battery error information to the display system 2. That is, the information that the disaster prevention system 1A transmits to the display system 2 in response to the request signal includes error information (storage battery error information in this operation example) related to the error that has occurred in the disaster prevention system 1A.

[0170] When the acquisition unit 252 acquires storage battery error information including new status information (step S31), the information image generation unit 258 generates a new information image Im5 based on the storage battery error information.

[0171] When the information image generating unit 258 generates the new information image Im5, the third output unit 261 causes the display unit 51 to display the new information image Im5 (see FIG. 18) on the map Mp6 in a superimposed manner.

[0172] The new information image Im5 includes, for example, the name of the facility 9A (first store), the name of the receiver 4 ("first receiver"), a character string representing the display of new information ("new information"), a character string indicating the value of the storage battery voltage of the storage battery 441 measured by the charge / discharge control unit 455 ("storage battery voltage: 20V"), and a character string indicating the deterioration state of the storage battery 441 ("storage battery state: abnormal (replacement required)"). Note that a part of the new information image Im5 (for example, a character string indicating the deterioration state of the storage battery 441) may be displayed in a manner different from other parts of the new information image Im5 to call the attention of the terminal user. For example, a part of the new information image Im5 may be displayed in a color, font, or the like different from other parts of the new information image Im5.

[0173] In other words, when the acquisition unit 252 of the display system 2 acquires new status information, the third output unit 261 causes the display unit 51 to display a display screen (new information display screen) P10 including a new information image Im5 and a map Mp6, as shown in FIG. 18 (step S32).

[0174] These operations of the linkage system 100 enable the terminal user to obtain the latest information on the disaster prevention system 1 at a location away from the facility 9 in which the disaster prevention system 1 is installed.

[0175] (4) Variations The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. In addition, the same function as the display system 2 may be embodied in a display method, a computer program, or a non-transitory recording medium on which a program is recorded, etc.

[0176] The display method according to one embodiment includes an acquisition step and a display control step. In the acquisition step, event information related to an abnormality detected by a disaster prevention system 1 installed in a facility 9 is acquired. In the display control step, a display screen P1 showing a map Mp1 including the occurrence position of the abnormality detected by the disaster prevention system 1 and the current position of a display terminal 5 including a display unit 51 is displayed on the display unit 51 based on the event information.

[0177] A (computer) program according to one aspect is a program for causing one or more processors to execute a display method.

[0178] Modifications of the above embodiment are listed below. The modifications described below can be applied in appropriate combinations.

[0179] In the above embodiment, as described in "(3.2) Example of Operation When an Error Occurs", when the acquisition unit 252 acquires error information from the disaster prevention system 1, the second output unit 260 displays the display screen P4 (see FIG. 10) or the display screen P5 (see FIG. 12) on the display unit 51. At this time, even if the display screen P4 or the display screen P5 is displayed on the display unit 51, when the acquisition unit 252 acquires event information, the second output unit 260 may display the display screen P1 (see FIG. 4) on the display unit 51 in preference to the event information based on the event information. As described in "(3.1) Example of Operation When an Anomaly Occurs", the display screen P1 includes a position related to the source of the anomaly (fire). Note that the event information is information related to an anomaly detected by the disaster prevention system 1, which is different from the error information. This allows the terminal user, who is the first user, to respond to the anomaly in preference to an error in the disaster prevention system 1, thereby reducing the possibility of a delay in responding to the anomaly.

[0180] In the above embodiment, the user determination unit 255 of the display system 2 determines the attribute of the terminal user (whether the user is the first user or the second user) based on attribute information registered in advance by the terminal user of the display terminal 5, but the attribute of the terminal user may be determined by unique ID information assigned to the display terminal 5. In this case, it is sufficient that the storage unit 24 of the display system 2 stores information regarding the correspondence between the ID information unique to the display terminal 5 and the attributes of the user of the display terminal. This eliminates the need for the terminal user to register attribute information.

[0181] The information selection image Im3 may include a character string for selecting acquisition of existing information ("Acquire existing information") and a character string for selecting acquisition of new information ("Acquire new information"), as well as a character string for generating new information (for example, "Generate new information"). When the terminal user taps on the character string for generating new information, the request unit 251 transmits to the receiver 4 a new information generation signal requesting the generation of new information (for example, status information on the degradation state of the storage battery 441). The information generated at this time may be acquired by tapping on "Acquire existing information" at any timing of the terminal user's choice.

[0182] The display system 2 in the present disclosure includes a computer system. The computer system is mainly composed of a processor and a memory as hardware. The processor executes a program recorded in the memory of the computer system, thereby realizing the function of the display system 2 in the present disclosure. The program may be pre-recorded in the memory of the computer system, may be provided through an electric communication line, or may be provided by being recorded in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits such as IC or LSI referred to here are called by different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, a field-programmable gate array (FPGA) that is programmed after the manufacture of the LSI, or a logic device that can reconfigure the connection relationship inside the LSI or reconfigure the circuit partition inside the LSI, can also be adopted as a processor. The electronic circuits may be integrated in one chip, or may be distributed among multiple chips. The multiple chips may be integrated into one device, or may be distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0183] Furthermore, it is not essential for the display system 2 that multiple functions are integrated into one housing, and the components of the display system 2 may be distributed across multiple housings. Furthermore, at least some of the functions of the display system 2 may be realized by, for example, the cloud (cloud computing) or the like.
