[0011] (1) Overview The drawings described in the following embodiments are schematic drawings, and the ratios of the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensional ratios.

[0012] The disaster prevention support method according to this embodiment relates to disaster prevention at a site 200 (see FIGS. 1 and 2), such as a work site or a construction site.

[0013] In this disclosure, a "site" refers to a location where construction or building-related activities are carried out. In this disclosure, "construction" refers to economic activities such as architecture, civil engineering, tunnels, bridges, roads, dams, river improvement, ports, airports, parks, or urban development. For example, the subject of "construction" may be a residential building such as a detached house or an apartment building, or a non-residential building such as a commercial building. In addition, in this disclosure, "building" refers to the economic activity of building a structure such as a ship. In the following, as an example, it is assumed that the site 200 is a construction site for a commercial building.

[0014] In the following, the event that is the target of disaster prevention measures is assumed to be a fire. However, the event that is the target of disaster prevention measures is not limited to a fire, but may also be a flood, earthquake, gas leak, or CO (carbon monoxide) generation due to incomplete combustion.

[0015] Here, a disaster prevention support method according to one embodiment of the present invention includes a support step. In the support step, a disaster prevention system 1 including at least one disaster prevention device 2 is loaned to a manager X1 (see FIG. 1) of the site 200, and a disaster prevention function is established for the site 200 during the activity period (here, the construction period) in which the activity is carried out. Hereinafter, the person who loans the disaster prevention system 1 may be referred to as the "lender," and the person who receives the loan of the disaster prevention system 1 may be referred to as the "loanee."

[0016] The manager X1 is a person who manages the site 200 that is scheduled to be constructed or is currently under construction, and is assumed to include a member of the construction company 502 that is contracted by a client (orderer) to construct a commercial building at the site 200. In other words, the manager X1 includes the person to whom the disaster prevention system 1 is loaned (the construction company 502). Therefore, the manager X1 may include a site supervisor X10 (the person in charge of the site 200) and an operator X12, who are members of the construction company 502.

[0017] According to this configuration, in the support step, the disaster prevention system 1 is loaned to establish a disaster prevention function for the site 200 during the activity period. Therefore, for the site 200 where strengthening disaster prevention is difficult to achieve due to issues such as cost, the loaned disaster prevention system 1 is likely to solve the problem. As a result, the disaster prevention support method has the advantage of making it easier to achieve strengthening disaster prevention at the site 200.

[0018] The administrator X1 may include not only the "loanee" but also a member of the maintenance company 501 (e.g., a maintenance worker X11) who installs and recovers the disaster prevention system 1 at the site 200. The administrator X1 may also include a member of the security company 503 (e.g., a security guard X13) who rushes to the site 200 upon receiving a report of a fire at the site 200.

[0019] A disaster prevention support system 100 according to another aspect of the present embodiment includes a disaster prevention system 1 including at least one disaster prevention device 2, and a support unit 31 (see FIG. 1). The support unit 31 lends the disaster prevention system 1 to a manager X1 of a site 200, and establishes a disaster prevention function for the site 200 during the activity period in which the activity is carried out. For example, the support unit 31 manages and supports data related to the lending of the disaster prevention system 1.

[0020] In the following, it is assumed that the functions of the support unit 31 are incorporated into a support server 3 that is located outside the site 200 and is composed of one server device. However, the functions of the support unit 31 may be incorporated into a plurality of server devices in a distributed manner, or such server devices may constitute, for example, a cloud (cloud computing).

[0021] This configuration also has the advantage of making it easier to strengthen disaster prevention measures at the site 200.

[0022] In this embodiment, the disaster prevention support method includes a presentation step in which advice information regarding the installation of a disaster prevention system 1 including at least one disaster prevention device 2 is presented to a manager X1 of the site 200. At the site 200, at least one of the shape and size of an activity area 300 (see FIG. 4) changes depending on the progress of the construction or building activity.

[0023] According to this configuration, the presentation step presents advice information regarding the installation of the disaster prevention system 1. This increases the likelihood that the disaster prevention system 1 can be easily installed at the site 200 in the activity area 300, whose shape or size at least may change depending on the progress of the activity. As a result, the disaster prevention support method has the advantage of being able to improve the ease of installing the disaster prevention system 1 at the site 200.

[0024] In this embodiment, the disaster prevention support system 100 includes a disaster prevention system 1 including at least one disaster prevention device 2, and a presentation unit 32 (see FIG. 1). The presentation unit 32 presents advisory information regarding the installation of the disaster prevention system 1 to a manager of a site 200 where at least one of the shape and size of the activity area 300 changes depending on the progress of activities related to construction or building. For example, the presentation unit 32 outputs the advisory information via the network NT1 to a presentation device 6 (see FIGS. 1 and 5) owned by a maintenance worker X11 of a maintenance company 501, and causes the presentation device 6 to present the advisory information.

[0025] In the following, it is assumed that the function of the presentation unit 32 is located outside the site 200 and is incorporated into the support server 3 in the same manner as the function of the support unit 31. However, the function of the presentation unit 32 may be incorporated into a housing (device) different from the housing (device) into which the function of the support unit 31 is incorporated. Furthermore, the function of the presentation unit 32 may be incorporated in a distributed manner into a plurality of server devices, and such server devices may constitute, for example, a cloud (cloud computing).

[0026] This configuration also has the advantage of making it easier to install the disaster prevention system 1 at the site 200.

[0027] (2)Details Hereinafter, an integrated system A1 including a disaster prevention support system 100 according to this embodiment will be described in detail with reference to FIGS.

[0028] (2.1) Overall structure of the integrated system As shown in FIG. 1, the integrated system A1 includes a disaster prevention support system 100 and a plurality of external devices 5 (a total of five in FIG. 1).

[0029] The disaster prevention support system 100 provides support for disaster prevention at a plurality of sites 200 (see FIGS. 1 and 2), such as work sites or construction sites. In the following, it is assumed that the plurality of sites 200 includes a first site 201 and a second site 202, as shown in FIG.

[0030] For the sake of convenience, the following description will assume that the first site 201 and the second site 202 are both construction sites contracted by the same construction company 502, but they may be construction sites of different construction companies. Also, it is assumed that the client requesting the construction of the building at the first site 201 is different from the client requesting the construction of the building at the second site 202, but they may be the same.

[0031] In the following description, it is assumed that the construction period at the first site 201 and the construction period at the second site 202 do not overlap, and that construction at the second site 202 begins after the construction period at the first site 201 ends. However, it is of course possible that at least a portion of the construction periods of the two sites overlap.

[0032] As an example, the disaster prevention support system 100 includes a plurality of disaster prevention systems 1 each including at least one disaster prevention device 2, and a support server 3.

[0033] The support server 3 is installed outside the site 200. It is assumed that the support server 3 is operated by, for example, a "lessor" who is the party that lends the disaster prevention system 1. The lessor is a leasing company 500, and the support server 3 is installed within the leasing company 500. The support server 3 is connected to a network NT1 (see FIG. 1) such as the Internet via a router or the like installed within the leasing company 500.

[0034] The leasing company 500 purchases one or more disaster prevention systems 1 from a company (hereinafter referred to as a "manufacturer") that manufactures and sells the disaster prevention systems 1. The detailed configurations of the disaster prevention system 1 and the support server 3 will be described in the following sections.

[0035] A leasing company 500 concludes a service contract for "leasing" and "disaster prevention support" with a construction company 502 (lessee), and leases (rents) one or more disaster prevention systems 1. In this embodiment, the construction of a commercial building is assumed, and therefore the lessee is a construction company 502 (a so-called general contractor). However, the lessee is not limited to the construction company 502, and may be, for example, a building contractor that undertakes the construction of a detached house or the like.

[0036] In short, in this embodiment, as an example, the leasing company 500 provides both the leasing service and the disaster prevention support service.

[0037] The leasing company 500 has a business partnership with a maintenance company 501. The leasing company 500 requests the maintenance company 501 to comprehensively perform tasks such as installation, collection, and cleaning of the disaster prevention system 1 that is the subject of the lease. For example, when the leasing company 500 concludes the above-mentioned service contract with the construction company 502, the leasing company 500 instructs the maintenance company 501 to install the disaster prevention system 1 at each of the first site 201 and the second site 202 under the jurisdiction of the construction company 502. The leasing company 500 receives payment of a service fee (including a lease fee) in consideration for providing the above-mentioned service. The leasing company 500 also performs credit management for the construction company 502, with which it has become a trading partner.

[0038] Incidentally, the leasing service and the disaster prevention support service may be provided by different parties. For example, the manufacturer may be responsible for disaster prevention support-related operations, and the leasing company 500 may be responsible for leasing-related operations (collection of lease fees, etc. and credit management). The manufacturer may, for example, sell the disaster prevention system 1 to the leasing company 500, pay a fixed monthly fee to the leasing company 500, and then return the disaster prevention system 1 (leaseback). In other words, the manufacturer has the right to use the disaster prevention system 1. The manufacturer instructs the maintenance company 501 to install and collect the disaster prevention system 1. In this case, the support server 3 may be operated by the manufacturer. The construction company 502 pays a service fee (including the lease fee) to the leasing company 500. The leasing company 500 passes a portion of the paid service fee to the manufacturer.

[0039] The plurality of external devices 5 (a total of five in the illustrated example) include, for example, a maintenance server 4, a presentation device 6, a monitoring server 70, an information terminal 71, and a security server 8, as shown in FIG.

[0040] The maintenance server 4 is a server operated by the maintenance company 501. The maintenance server 4 is installed, for example, inside the maintenance company 501. The maintenance server 4 is connected to the network NT1 via a router or the like installed inside the maintenance company 501. The maintenance server 4 is capable of bidirectional communication with the support server 3 operated by the leasing company 500 via the network NT1. The maintenance server 4 may also be capable of bidirectional communication with other external devices 5 via the network NT1.

[0041] The presentation device 6 is assumed to be an information terminal such as a smartphone or tablet terminal carried by a member of the maintenance company 501 (for example, a maintenance worker X11). When the maintenance worker X11 carrying the presentation device 6 is outside the company, the presentation device 6 is connected to the network NT1 via a mobile phone network (carrier network) provided by a telecommunications company or a public wireless LAN (Local Area Network).

[0042] Although details will be described later, advice information regarding the installation of the disaster prevention system 1 is presented through the presentation device 6. The presentation device 6 has a display unit 60 (see FIG. 5) including a touch panel type liquid crystal display or an organic EL (Electro-Luminescence) display, and it is assumed that "presentation of advice information" is performed by screen output from the display unit 60. The presentation device 6 is pre-installed with dedicated application software (hereinafter simply referred to as "presentation app") for communicating with the support server 3 etc. and presenting a GUI (Graphical User Interface) regarding the advice information. The advice information is transmitted to the presentation device 6 directly from the support server 3 or from the support server 3 via the maintenance server 4.

[0043] The maintenance worker X11 uses the presentation device 6 to perform installation work and collection work of the disaster prevention system 1 at each site 200. The maintenance worker X11 also uses the presentation device 6 to manage and monitor various conditions related to the disaster prevention system 1. The maintenance worker X11 also performs cleaning work for the disaster prevention system 1.

[0044] The presentation device 6 may be a stationary personal computer equipped with a display unit (display), etc. Furthermore, the "presentation of advice information" is not limited to screen output, and may be performed by audio output instead of or in addition to the screen output.

[0045] The monitoring server 70 is a server operated by the construction company 502. The monitoring server 70 is installed, for example, inside the construction company 502. The monitoring server 70 is connected to the network NT1 via a router or the like installed inside the construction company 502. The monitoring server 70 is capable of bidirectional communication with the support server 3 operated by the leasing company 500 via the network NT1. The monitoring server 70 is also capable of bidirectional communication with each disaster prevention system 1 and the security server 8 via the network NT1. The monitoring server 70 may also be capable of bidirectional communication with other external devices 5 via the network NT1.

[0046] An operator X12 of the construction company 502 manages and monitors the status of each site 200 using a terminal (for example, a personal computer) connected to the monitoring server 70 via an in-house LAN.

[0047] The information terminal 71 is assumed to be a smartphone or tablet terminal carried by a person of the construction company 502 (for example, the site supervisor X10 or the operator X12). The information terminal 71 may also be a wearable terminal (wearable computer) that can be attached or worn by a person. When the site supervisor X10 carrying the information terminal 71 is outside the company (for example, at the construction site 200), the information terminal 71 is connected to the network NT1 via a mobile phone network or a public wireless LAN provided by a telecommunications carrier.

[0048] As will be described in detail later, when the disaster prevention system 1 detects the outbreak of a fire at the site 200, the fact (fire information) is notified to the information terminal 71, etc. via the network NT1. Note that hereinafter, the detection of a fire by the sensor 21 of the disaster prevention system 1 may be simply referred to as "a fire has occurred."

[0049] The information terminal 71 has a display unit including a touch panel type liquid crystal display or an organic EL display, and it is assumed that the "notification" of fire information is performed by screen output of the display unit. The information terminal 71 is pre-installed with dedicated application software (hereinafter simply referred to as the "notification app") for communicating with the disaster prevention system 1 and presenting a GUI related to fire information. The fire information is transmitted to the information terminal 71 directly from the disaster prevention system 1 or from the disaster prevention system 1 via the monitoring server 70.

[0050] The notification information output through the notification app upon receiving the fire information includes information that can identify the site 200 where the fire occurred (such as the address, the details of the construction work, and the name of the client). The notification information also includes, for example, simple map information about the surrounding area where the site 200 is located. It is preferable that the map information display a marker indicating the location of the site 200 and a marker indicating the location within the site 200 where the fire was detected (the location of the interlocking source detector 21).

[0051] The disaster prevention device 2 of the disaster prevention system 1 may acquire its current location information using a satellite positioning system such as a GPS (Global Positioning System), and transmit the location information together with fire information to the information terminal 71. The notification information may display a marker indicating the GPS position of the disaster prevention device 2 on map information. The information terminal 71 may also acquire its current location information using a satellite positioning system such as a GPS, and display a marker indicating the current location of the information terminal 71 on map information.

[0052] The notification information may include image information of the fire site 200. The image information may include real-time video or still images of the fire site 200 captured by an imaging unit (camera, etc.). The imaging unit may be attached to the disaster prevention equipment 2 or may be installed separately from the disaster prevention equipment 2. The "notification" of the fire information is not limited to screen output, and may be performed by audio output instead of or in addition to screen output.

[0053] Security server 8 is a server operated by security company 503. Construction company 502 partners with security company 503 for disaster prevention and crime prevention services. Security server 8 is installed, for example, inside security company 503's premises. Security server 8 is connected to network NT1 via a router or the like installed inside security company 503's premises. Security server 8 can communicate bidirectionally with monitoring server 70 and information terminal 71 operated by construction company 502 via network NT1.

[0054] For example, if a fire breaks out at a construction site 200, a security guard X13 of a security company 503 will rush to the construction site 200 at a request from the construction company 502. The security server 8 receives the request (information) from the construction company 502 from the monitoring server 70 or the information terminal 71. The request from the construction company 502 may be conveyed to the security guard X13 orally over the telephone by the site supervisor X10 or the operator X12, etc. Note that the security guard X13 also makes regular patrols of each construction site 200 at the request of the construction company 502, even during normal times when no fire has occurred.

[0055] The security server 8 may be able to communicate directly with each disaster prevention system 1 via the network NT1. The above-mentioned fire information may be transmitted directly from each disaster prevention system 1 to the security server 8. The security server 8 may also be able to communicate bidirectionally with other external devices 5 via the network NT1.

[0056] (2.2) Disaster prevention system Next, the configuration of the disaster prevention system 1 to be loaned will be described with reference to Figures 2 and 3A. The disaster prevention system 1 described below is merely one example that can be loaned to each site 200, and it is sufficient that the system includes at least one disaster prevention device 2. However, it is desirable that the disaster prevention system 1 has a communication function for notifying an outside of the site 200 of fire information in the event of a fire occurring at the site 200.

[0057] In this embodiment, the number and types of disaster prevention devices 2 may vary depending on the scale of the construction site 200, the type of construction work, the number of on-site workers, etc. For example, the number and types of disaster prevention devices 2 installed at the first construction site 201 may differ from those installed at the second construction site 202.

[0058] Furthermore, the shape and / or size of the activity area 300 (see FIG. 4) at each construction site 200 may change depending on the progress of the construction work. Therefore, in this embodiment, even at the same construction site 200, the number and types of disaster prevention devices 2 installed will change over time.

[0059] 2, the disaster prevention system 1 includes a plurality of (five in the illustrated example) disaster prevention devices 2. The plurality of disaster prevention devices 2 include a plurality of (two in FIG. 2) sensors 21, an adapter 23 (reporting contact adapter), lighting devices 22, and a communication device 24.

[0060] The disaster prevention equipment 2 may be electrically connected to an external power source (e.g., a commercial power system) and may be driven by converting AC power (e.g., 100 V effective value) supplied from the external power source into DC current. However, at the construction site 200, it is highly likely that the disaster prevention equipment 2 will not be able to obtain power from an external power source. Therefore, in this embodiment, as an example, all of the disaster prevention equipment 2 is battery-powered. In other words, the disaster prevention equipment 2 is driven by power from an internal battery. Therefore, the disaster prevention system 1 can be used even if there is no external power source or emergency power source at the construction site 200.

[0061] As the construction work progresses and the construction period approaches, it may become easier to obtain power from an external power source. In this case, at least one of the disaster prevention devices 2 may be replaced with one that is powered by an external power source.

[0062] Each detector 21 has a detection function for detecting the occurrence of a fire. There is a high possibility that dust particles from building materials are floating in the air at the fire site 200. Therefore, each detector 21 is configured as a heat-sensitive detector that detects the occurrence of a fire in response to heat associated with the occurrence of a fire.

[0063] However, at least one of the multiple detectors 21 may be configured as a photoelectric detector that detects the occurrence of a fire based on the amount (concentration) of smoke generated by the occurrence of a fire. Alternatively, at least one of the multiple detectors 21 may have both thermal and photoelectric functions. In this case, the detector 21 may switch its operation so that it detects fires by heat during the daytime when there is a high possibility of dust and other particles floating around, and detects fires by smoke during the nighttime when construction work is suspended. Furthermore, at least one of the multiple detectors 21 may be configured as a multi-gas sensor that can detect various gas types.

[0064] Furthermore, it is preferable that each sensor 21 has a waterproof structure, considering that it may be installed at a construction site 200 where the walls, ceiling, etc. are not yet completed depending on the construction situation.

[0065] Each sensor 21 also functions as an alarm that notifies the surrounding area when it detects the occurrence of a fire, and therefore outputs a sound such as an alarm when a fire occurs.

[0066] The multiple sensors 21 are so-called interlocking sensors, and are configured so that when any one of the sensors 21 detects a fire, it will interlock with the other sensors 21 (together with the other sensors 21) and issue an audible alarm. The sensor 21 located at the source of the fire (interlocking source) will issue an audible alarm, for example, "Buzz buzz, there's a fire." The other sensors 21 (interlocking destinations) will issue an audible alarm, for example, "Buzz buzz, there's a fire somewhere else."

[0067] Specifically, for example, one of the multiple sensors 21 functions as a master sensor, and the remaining sensors 21 function as slave sensors. The master sensor 21 stores identification information of the other slave sensors 21. The setting of each sensor 21 as a master sensor or a slave sensor is switched by a DIP switch or the like attached to the sensor 21. The setting of the master sensor or slave sensor is performed at the site 200, for example, by a maintenance worker X11.

[0068] If the slave unit is the interlocking source, it sends an interlocking signal to the master unit indicating that it has detected a fire. Upon receiving the interlocking signal, the master unit issues an alarm sound and also sends an interlocking signal to the other slave units to cause them to issue alarm sounds. Even when the master unit is the interlocking source, it also sends an interlocking signal to all slave units to cause them to issue alarm sounds. The master unit also sends an alarm signal to adapter 23 indicating that it has detected a fire.

[0069] 3A, each sensor 21 has a control unit 210, a communication unit 211, a (built-in) battery 212, an alarm unit E1 (a working light 213 and an audio unit 215), and a detection unit 216. The battery 212 is, for example, a lithium battery, and the sensor 21 operates using power supplied from the battery 212.

[0070] The control unit 210 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 (applications) stored in one or more memories to function as the control unit 210. Here, the programs are pre-recorded in the memory of the control unit 210, but they may also 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.

[0071] The control unit 210 stores the unique identification information of the own device. If the own device is a parent device, the control unit 210 stores the unique identification information of the child device.

[0072] The control unit 210 controls the communication unit 211, the notification unit E1, the detection unit 216, etc. The control unit 210 also controls a power supply circuit that generates operating power for various circuits from DC power of the battery 212.

[0073] The detection unit 216 is a heat-sensitive sensor. The detection unit 216 has one or more heat detection elements such as thermistors. Each heat detection element detects heat at a temperature corresponding to a fire and transmits an electric signal (detection signal) to the control unit 210. The control unit 210 determines whether a fire has occurred based on the detection signal from the detection unit 216. The detection unit 216 may have a photoelectric sensor instead of or in addition to the heat-sensitive sensor.

[0074] The communication unit 211 transmits and receives wireless signals using radio waves as a medium. The communication unit 211 communicates with the communication units 211 of other sensors 21. If the sensor 21 itself is a master sensor, the communication unit 211 communicates with the adapter 23 (report transfer contact adapter). The communication unit 211 has an antenna, a transmission circuit, and a reception circuit. The transmission circuit modulates data input from the control unit 210 into a wireless signal and transmits it via the antenna. The reception circuit demodulates the wireless signal received via the antenna and outputs the demodulated data to the control unit 210.

[0075] The communication unit 211 performs wireless communication in accordance with, for example, the "radio station for low-power security systems" stipulated in Article 6, Paragraph 4, Item 3 of the Radio Law Enforcement Regulations, and performs wireless communication with other sensors 21 and adapters 23 using radio waves in the 426 MHz frequency band.

[0076] The notification unit E1 is composed of an operating light 213 and an audio unit 215. The notification unit E1 has a function of notifying the surrounding area of ​​the occurrence of a fire.

[0077] The acoustic unit 215 outputs sound (sound waves). When the control unit 210 determines that a fire has occurred, the acoustic unit 215 outputs an alarm sound to notify the occurrence of the fire. The acoustic unit 215 is composed of a speaker that converts an electrical signal into sound, an acoustic circuit, etc. Furthermore, when the control unit 210 determines that replacement is required, a malfunction has occurred, or the battery has run out, the acoustic unit 215 outputs a sound (alert sound) to notify the occurrence. The acoustic unit 215 also experimentally outputs the alarm sound and the alert sound during an operation test.

[0078] The operation test can be performed by pressing an operation button exposed from the housing 20 of each detector 21. In particular, by pressing an operation button attached to the adapter 23, operation tests of multiple detectors 21 can be performed in conjunction with each other.

[0079] If the operation button of the detector 21 or the adapter 23 is pressed during the alarm, the output of the alarm sound will stop.

[0080] The operation light 213 has an LED (Light Emitting Diode) 214 as a light source, an illumination circuit, and the like. The operation light 213 is normally off (during fire monitoring). When the control unit 210 determines that a fire has occurred, the operation light 213 starts flashing or lighting up together with the start of an alarm sound, and stops when the alarm sound stops. Furthermore, when the control unit 210 determines that replacement time, a malfunction, a dead battery, or the like has occurred, the operation light 213 flashes to notify people in the vicinity of the occurrence. In other words, people working at the site 200 can check the operating status of the detector 21 by visually checking the operation light 213.

[0081] The adapter 23 (report contact adapter) is configured to communicate wirelessly with the parent detector 21. As described above, when the parent detector 21 detects a fire in its own detector or one of the child detectors 21, it transmits an alarm signal indicating this to the adapter 23. The alarm signal includes information that can identify the interlocking detector 21 that caused the fire (e.g., identification information of the detector 21, etc.). The adapter 23 is installed, for example, near the entrance to the activity area 300 (see FIG. 5).

[0082] As described above, the adapter 23 also has operation buttons for stopping alarms from multiple detectors 21 in a coordinated manner and for executing operational tests in a coordinated manner. The adapter 23 is battery-powered and operates on power supplied from a built-in battery such as a lithium battery.

[0083] Here, the adapter 23 is communicatively connected to the lighting device 22 and the communication device 24 at least at the site 200. Specifically, the adapter 23 is connected to the lighting device 22 and the communication device 24 via two signal lines L1 (schematically shown as one line in FIG. 2 ) in a crossover wiring system. The adapter 23 has a pair of no-voltage terminals (report contacts). Upon receiving an alarm signal from the parent detector 21, the adapter 23 closes the report contact (a-contact) to turn on the lighting device 22 and further causes the communication device 24 to transmit fire information to external devices 5 such as the information terminal 71 and the monitoring server 70. In other words, upon receiving an alarm signal from the parent detector 21, the adapter 23 outputs a no-voltage report via the signal line L1 to the lighting device 22 and the communication device 24. When an operation button is pressed during report transfer, the adapter 23 opens the report contact to stop the report transfer output.

[0084] The lighting device 22 has a light source such as an LED, a lighting circuit for lighting the light source, and the like. When the lighting device 22 receives a report from the adapter 23 via the signal line L1, it turns on the light source. In other words, the disaster prevention support method includes at least a lighting step of turning on the lights at the site 200 in conjunction with the occurrence of an event (fire) that is the subject of disaster prevention measures, when the event (fire) occurs at the site 200. Here, the lighting device 22 is installed near the entrances and exits of the activity area 300 or along the evacuation route as lighting for evacuation guidance (see FIG. 5).

[0085] The lighting device 22 is configured to be easily installable at the site 200. It is preferable that the lighting device 22 has a small housing that is easy to carry. The lighting device 22 is battery-powered and is assumed to operate on power supplied from a built-in battery such as a lithium battery, but may also operate on power supplied from an external battery (for example, a UPS (Uninterruptible Power Supply)).

[0086] If the lighting devices 22 are installed at the construction site 200, the lighting devices 22 turn on when a fire is detected, thereby providing an environment in which people at the construction site 200 can easily evacuate. As a result, people at the construction site 200 can quickly evacuate when a fire occurs. In particular, if a fire occurs and a power outage occurs while construction site workers are performing construction work in an environment where it is difficult to ensure sufficient lighting, such as a basement, the lighting devices 22 can be turned on to prevent people from being late in evacuating.

[0087] The communication device 24 has a communication function for communicating with external devices 5, such as the information terminal 71 and the monitoring server 70, via the network NT1. When the communication device 24 receives a report from the adapter 23 via the signal line L1, it generates a wireless signal indicating fire information, including identification information of the interlocking source detector 21, and transmits the signal to the information terminal 71, the monitoring server 70, and other predetermined external devices 5. In particular, the site supervisor X10 may change depending on the site 200 where the system is installed, and the information terminal 71 to which the fire information is to be sent may also change. Therefore, each time the disaster prevention system 1 is rented, the identification information specifying the destination in the memory of the communication device 24 is changed. The communication device 24 is installed, for example, near the entrance / exit of the activity area 300 (see FIG. 5).

[0088] When the information terminal 71 and the monitoring server 70 receive the fire information from the communication device 24, they identify the location of the site 200 where the disaster prevention system 1 is installed, etc., based on the unique identification information of the interlocking source detector 21 and the rental information M1 (see FIG. 3B) described later. The information terminal 71 launches a notification app and displays the location of the site 200, etc., on a screen. The support server 3 manages the rental information M1. The information terminal 71 and the monitoring server 70 each acquire the rental information M1 from the support server 3. The acquisition timing is not particularly limited, and may be when installation at the site 200 is completed or when fire information is received. Furthermore, as described above, if the disaster prevention device 2 acquires its own location information using GPS, the GPS-based location information may be displayed on the screen of the information terminal 71.

[0089] Each disaster prevention device 2 of this embodiment has a mounting portion 26 (see FIG. 6B) to facilitate installation at a construction site 200 where the walls, ceiling, and other surfaces are incomplete. FIG. 6B is a schematic side view showing the detector 21 installed on a steel frame T1 that forms the framework of the building at the construction site 200. The mounting portion 26 is formed, for example, by a magnet fixed to the upper surface of the base of the housing of each disaster prevention device 2 (in FIG. 6, the mounting base of the housing 20 of the detector 21). The mounting portion 26 may be formed by double-sided tape or a hook structure. By providing the mounting portion 26 in this manner, the disaster prevention device 2 can be installed directly on the base of the wall or ceiling of a building, or on temporary scaffolding, etc.

[0090] (2.3) Support Server Next, the configuration of the support server 3 operated by the lessor who lends the disaster prevention system 1 will be described with reference to FIGS. 1 and 3B.

[0091] 1 and 3B, the support server 3 includes a processing unit 30. The support server 3 further includes a communication unit 33 and a storage unit 34, as shown in FIG.

[0092] The communication unit 33 is a communication interface for the support server 3 to communicate with each of the plurality of external devices 5 via the network NT1.

[0093] The memory unit 34 is composed of a readable and writable memory. The memory unit 34 is, for example, a flash memory. The memory unit 34 is provided outside the processing unit 30, but may also be provided inside the processing unit 30. In other words, the memory unit 34 may be an internal memory of the processing unit 30. The memory unit 34 stores the loan information M1. The memory unit 34 also stores identification information of the communication device 24 of the disaster prevention system 1 and identification information of multiple external devices 5. The memory unit 34 also stores various other data.

[0094] The processing unit 30 can be realized, for example, by 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 (applications) stored in one or more memories to function as the processing unit 30. Here, the programs are pre-recorded in the memory of the processing unit 30, but they may also 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. The processing unit 30 has a support unit 31 and a presentation unit 32. In other words, the processing unit 30 has the function of the support unit 31 and the function of the presentation unit 32.

[0095] The support unit 31 is configured to lend the disaster prevention system 1 to a manager X1 (e.g., construction company 502) of the site 200, and establish a disaster prevention function for the site 200 during a construction period (activity period) when construction (activity) is carried out. In other words, the disaster prevention support method includes a support step of lending the disaster prevention system 1 to the manager X1 of the site 200, and establishing a disaster prevention function for the site 200 during a construction period (activity period) when construction (activity) is carried out. Here, the support unit 31 stores and manages data related to the lending of the disaster prevention system 1 (hereinafter referred to as "lending information M1") in the memory unit 34.

[0096] [Lending Information] The rental information M1 will now be described. The rental information M1 is data that associates first information about the disaster prevention system 1 to be rented, second information about the site 200 and construction company 502 where the disaster prevention system 1 will be installed, and third information about the rental period. The rental information M1 is generated, for example, for each disaster prevention system 1 to be rented, that is, for each disaster prevention system 1 to be installed at the site 200. When the rental period of the disaster prevention system 1 ends, the above association is dissolved, and the rental information M1 is stored as historical information.

[0097] The first information includes information on the number, type, and unique identification information of the disaster prevention devices 2 included in the loaned disaster prevention system 1. The type information may include, for example, items related to the type of the detector 21, lighting device 22, adapter 23, or communication device 24, and items related to the type of the detector 21, whether it is thermal or photoelectric. The type information may include a product number or model number.

[0098] The storage unit 34 stores catalog information (master information) regarding the disaster prevention equipment 2 that can be rented by the leasing company 500. The catalog information is acquired by downloading from, for example, a manufacturer's server. The type information, identification information, and the like of the first information are information based on the catalog information.

[0099] The second information includes information about the construction company 502, which is the party (customer) to whom the disaster prevention system 1 is leased. The second information also includes information about the site 200 where the disaster prevention system 1 will be installed (such as the location, size, construction content, and number of on-site workers). The second information is information based on customer information (master information) that may be registered at the time a service contract is concluded between the leasing company 500 and the construction company 502.

[0100] As described above, the third information is information regarding the rental period. The rental period generally coincides with the construction period at the construction site 200, but this does not necessarily coincide. The support unit 31 generates rental status information based on the third information and manages whether multiple disaster prevention devices 2 are currently on loan. The rental status information is stored in the memory unit 34. In other words, the disaster prevention support method further includes a management step of managing rental status information indicating whether multiple disaster prevention devices 2 to be loaned are currently on loan. The support unit 31 outputs the rental status information to a display of a user terminal, such as a personal computer, of a person (e.g., a person in charge) at the leasing company 500. The rental status information is also transmitted to the maintenance server 4 and the presentation device 6, etc., and shared with the maintenance company 501. Managing the rental status information in this manner facilitates management of the disaster prevention system 1. For example, the type and number of disaster prevention devices 2 that are not currently on loan and are stored in a warehouse, etc., can be easily identified.

[0101] In the present embodiment, as an example, the support unit 31 sets a group for two or more pieces of disaster prevention equipment 2 to be loaned. Then, the support unit 31 manages the loaning of the disaster prevention equipment 2 in groups. Specifically, the support unit 31 assigns a group ID to two or more pieces of disaster prevention equipment 2 to be loaned to one site 200, and manages the loan information M1 by linking the group ID with a loan period (third information). In other words, the disaster prevention support method includes a setting step of setting a group for two or more pieces of disaster prevention equipment 2 to be loaned. When the loan period ends, the set group is dissolved, and when the equipment is loaned to a new site 200, the group is reset. Setting a group makes it easier to manage the disaster prevention system 1. However, the support unit 31 may also manage the loan period in units of disaster prevention equipment 2.

[0102] The support server 3 of this embodiment is configured to receive a rental request (signal) from a construction company 502 requesting the rental of a disaster prevention system 1 to be installed at a certain construction site 200. Upon receiving the rental request, the support server 3 estimates and proposes the number and type of disaster prevention equipment 2 based on the size (building area, etc.) of the construction site 200, the construction period, the construction content, the number of on-site workers, etc. The construction content may, for example, be residential or non-residential, and whether the construction is wooden, reinforced concrete, or steel. The storage unit 34 stores multiple models (which may be machine learning models) based on the size of the construction site 200, the construction content, the number of on-site workers, etc. As a specific example, a model corresponding to the construction of a small building includes information such as five sensors 21, one adapter 23, one lighting device 22, and one communication device 24. In addition to the above models, the support server 3 generates proposal information based on BIM (Building Information Modeling) data. The BIM data includes the shape of the building, spatial relationships, geographic information, the quantity and characteristics of building components, and may also include data in which the building is represented by a three-dimensional model. It is assumed that the support server 3 receives a loan request including BIM data of the target site 200 from an external device 5 such as a monitoring server 70 or an information terminal 71.

[0103] When the support unit 31 receives a loan request for a certain construction site 200 via the communication unit 33, it selects a model that matches the construction site 200 from multiple models stored in the storage unit 34. Then, the support unit 31 generates proposal information including the recommended number and type of disaster prevention devices 2 based on the selected model, and transmits the proposal information to the sender of the loan request (e.g., the monitoring server 70 or the information terminal 71). The proposed information preferably represents the maximum number and type of disaster prevention devices estimated to be required for the final scale of the construction site 200 at the end of the construction period. When the support unit 31 receives a positive response from the sender (e.g., the monitoring server 70 or the information terminal 71) to which the proposal information was sent, the support unit 31 determines the number and type of disaster prevention devices 2 to be loaned based on the proposal information. Of course, the number and type of disaster prevention devices 2 to be loaned may also be determined based on a direct specification from the construction company 502. When the support unit 31 receives a negative response to the proposal information, it selects a different model and transmits different proposal information (re-proposal).

[0104] Once the number and type of disaster prevention equipment 2 to be loaned, the loan period, etc. have been determined, the support unit 31 generates loan information M1 based on the first information, the second information, and the third information. The generated loan information M1 is stored in the storage unit 34. Note that when the support unit 31 generates the loan information M1, if there is any missing information regarding the first information, the second information, and the third information, a person in charge at the leasing company 500 inputs the information appropriately using a user terminal.

[0105] The support unit 31 transmits an installation request (signal) to the maintenance server 4 or the presentation device 6, etc., in accordance with the generated rental information M1, and requests the maintenance company 501 to install the disaster prevention system 1 at the target site 200. The installation request includes at least information for identifying the site 200 and information for identifying the disaster prevention equipment 2 to be installed.

[0106] Based on the received installation request, the maintenance worker X11 of the maintenance company 501 prepares the disaster prevention equipment 2 to be installed, transports it to the site 200, and performs the installation work. The transportation work and the installation work may be performed at different times. Depending on the progress of the construction, for example, it may be difficult to secure a place to install the detectors 21, etc., soon after construction has started (at the foundation work stage). Therefore, the installation work may start a predetermined period after the start of construction.

[0107] Then, when the loan period is about to end, the support unit 31 sends a collection request (signal) to the maintenance server 4 or the presentation device 6, etc., and requests the maintenance company 501 to collect the disaster prevention system 1 from the target site 200.

[0108] Here, the disaster prevention system 1 of this embodiment is reused at a site 200 different from the site 200 after the construction period (activity period). That is, after the rental period for the first site 201 ends and the maintenance worker X11 retrieves the disaster prevention system 1, when the rental period for the second site 202 begins, the maintenance worker X11 installs the retrieved disaster prevention system 1 at the second site 202 in response to an installation request. As a result, disposal of the disaster prevention system 1 can be suppressed, and the loaned disaster prevention system 1 can be effectively utilized.

[0109] The disaster prevention system 1 installed at the site 200 is likely to be dirty due to dust from building materials and exposure to wind and rain, and if the detector 21 is particularly dirty, there is a possibility that a false detection of a fire may occur. Therefore, when the maintenance worker X11 retrieves the disaster prevention system 1 from the site 200, he or she cleans the disaster prevention system 1 in preparation for reuse.

[0110] After the construction of the commercial building is completed (after completion), a disaster prevention system other than the disaster prevention system 1 is installed in the commercial building. In other words, a disaster prevention system other than the loaned disaster prevention system 1 is installed at the construction site 200 after the construction period (activity period). The "other disaster prevention system" includes, for example, all brand new disaster prevention equipment 2. The types and number of disaster prevention equipment 2 of the "other disaster prevention system" may be the same as those of the loaned disaster prevention system 1, but are generally assumed to be different. If the building is a commercial building, as in this embodiment, the "other disaster prevention system" is an automatic fire alarm system that includes multiple sensors 21, as well as receivers, transmitters, emergency broadcast equipment, and the like. In this way, since the "other disaster prevention system" is installed after the construction period, it is easier to provide a disaster prevention system 1 to be loaned that emphasizes simplicity as a stopgap until completion.

[0111] However, the disaster prevention system 1 may include one or more pieces of disaster prevention equipment 2 that are continuously installed at the construction site 200 even after the construction period (activity period). For example, one or more pieces of disaster prevention equipment 2 may remain installed on the ceiling surface until a tenant moves into the constructed commercial building, and even after the tenant moves in. In this case, too, the effort and cost of introducing and installing new, separate disaster prevention equipment 2 in the constructed commercial building can be saved, and the loaned disaster prevention system 1 can be used effectively.

[0112] The disaster prevention system 1 may include one or more pieces of disaster prevention equipment 2 that can be purchased by the administrator X1 at the end of the construction period (activity period). For example, the one or more pieces of disaster prevention equipment 2 that have been loaned may be purchased by the construction company 502, or if a security company 503 will be in charge of building management of the commercial building after construction, the security company 503 may purchase them. In this case as well, the loaned disaster prevention system 1 can be effectively utilized. The administrator X1 may request payment for the one or more pieces of disaster prevention equipment 2 that have been purchased from the client (owner).

[0113] (2.4) Expiration date management In addition to managing the rental status information described above, the support unit 31 of this embodiment manages information relating to at least one of (here, for example, both) the expiration date and the number of times the system has been used (rented) for the disaster prevention system 1. In other words, in the management step, information relating to at least one of (here, for example, both) the expiration date and the number of times the system has been used (rented) for the disaster prevention system 1 is further managed.

[0114] Specifically, as described above, each disaster prevention device 2 of the disaster prevention system 1 of this embodiment is installed at a construction site 200 where it is difficult to obtain power from an external power source, and therefore operates on power from a (built-in) battery. However, for example, if the battery (battery 212) of the detector 21 runs out during the loan period, there is a possibility that a false alarm will occur at the site 200. Furthermore, as described above, the disaster prevention system 1 is reused at multiple sites 200, and therefore there is a possibility that the disaster prevention devices 2 will be loaned out at all times.

[0115] Therefore, the support unit 31 manages the expiration date for each piece of disaster prevention equipment 2 in the disaster prevention system 1. The support unit 31 stores and manages the "expiration date" based on the replacement period (for example, 10 years) for each piece of disaster prevention equipment 2 and the replacement period (for example, several years) for the (built-in) battery in the memory unit 34. The support unit 31, for example, periodically determines whether there is any disaster prevention equipment 2 whose expiration date is about to expire, and notifies the maintenance server 4 or the presentation device 6, etc. of the determination result. If there is any disaster prevention equipment 2 whose expiration date is about to expire, the maintenance worker X11 excludes that disaster prevention equipment 2 from being available for loan, or replaces the battery.

[0116] In particular, if there is any disaster prevention equipment 2 nearing the end of its usage period in the disaster prevention system 1 currently being rented based on the rental status information, the support unit 31 sends a replacement notice to the maintenance server 4 or the presentation device 6, etc. In other words, the leasing company 500 requests the maintenance company 501 to replace the target disaster prevention equipment 2 (or just the battery) currently installed at the site 200 by sending the replacement notice.

[0117] The support unit 31 also stores and manages the number of times the disaster prevention system 1 has been used (actual number of times) for each disaster prevention device 2 in the memory unit 34. The support unit 31 counts the number of times each disaster prevention device 2 has been used by, for example, "+1" for each loan, that is, "+1" for each time the device has been installed at a site 200 and then collected. The more times it has been used, the higher the possibility that the disaster prevention device 2 has deteriorated. The support unit 31, for example, periodically determines whether there is any disaster prevention device 2 whose number of times of use has reached a threshold number, and notifies the maintenance server 4, the presentation device 6, or the like of the determination result.

[0118] A plurality of thresholds may be set. In this case, for example, when the number of times of use reaches a first threshold, the support unit 31 issues a notice to conduct an operational inspection of the disaster prevention equipment 2. Furthermore, when the number of times of use reaches a second threshold that is greater than the first threshold, the support unit 31 issues a notice to exclude the disaster prevention equipment 2 from being available for loan.

[0119] In this way, by managing information relating to at least one of the expiration date and the number of times of use, it is possible to reduce the possibility that disaster prevention equipment 2 that is close to the time for replacement will be installed at the site 200, for example.

[0120] (2.5) Remote Monitoring In the disaster prevention support system 100 of this embodiment, the loaned disaster prevention system 1 is configured so as to be capable of being remotely managed or monitored.

[0121] As described above, the disaster prevention system 1 of this embodiment notifies the outside when it detects a fire at the construction site 200. In other words, the disaster prevention support method further includes a notification step of notifying the external device 5 when at least an event that is a target of disaster prevention (here, a fire) occurs at the construction site 200. As described above, when the communication device 24 of the disaster prevention system 1 receives a report from the adapter 23, it generates a wireless signal indicating the fire information and transmits it to the external device 5, such as the information terminal 71, the monitoring server 70, and the security server 8. Therefore, the construction company 502 and the security company 503 can remotely monitor the presence or absence of a fire at the construction site 200. As a result, even a rental disaster prevention system 1 can easily provide the external notification function, improving convenience. In this embodiment, the fire information is also transmitted to the support server 3 together with environmental information, which will be described later, for collection and analysis as big data.

[0122] The communication device 24 of the disaster prevention system 1 not only transmits information to the outside when it detects the occurrence of a fire, but also transmits environmental information of the site 200 to the support server 3, for example, periodically.

[0123] The environmental information may include, for example, the ambient temperature and humidity at the site 200. The environmental information may also include information about the air quality at the site 200, i.e., information about the amount of substances detected in the air depending on their types and concentrations. The environmental information may also include images (still images or video) of the site 200. The disaster prevention system 1 of this embodiment includes a temperature and humidity sensor, an air quality sensor, and an imaging unit (such as a camera). These sensors and imaging units are assumed to be attached to any of the detector 21, the adapter 23, the lighting equipment 22, and the communication device 24, but may also be provided separately. If the detection unit 216 of the detector 21 is photoelectric, the information about the air quality may be information obtained from a detection signal detected by the detection unit 216. The environmental information may also include information about the communication status (such as received signal strength).

[0124] The communication device 24 periodically transmits the environmental information, for example, several times a day, to the support server 3. Furthermore, when a fire occurs, the communication device 24 transmits the environmental information at the time of the occurrence together with the fire information to the support server 3. The environmental information may be transmitted in response to an environmental request signal from the support server 3.

[0125] For example, the support unit 31 analyzes the situation of the site 200 based on the environmental information. The support unit 31 also analyzes whether or not each disaster prevention device 2 is correctly installed in a specific location at the site 200. If the analysis reveals that the number of installed disaster prevention devices 2 is incorrect or that the disaster prevention devices 2 are installed in a location different from the specific location, the support unit 31 notifies the maintenance server 4 or the like of an error.

[0126] Furthermore, based on the environmental information, the support unit 31 re-proposes an installation location of the disaster prevention equipment 2 that is more suitable for the site 200. For example, if the support unit 31 obtains from the environmental information an analysis result that a certain sensor 21 currently being installed is installed in a location with a lot of dust, etc., the support unit 31 notifies the maintenance server 4 or the like to relocate the sensor 21.

[0127] In this way, the support server 3 remotely manages or monitors the installation status of the disaster prevention system 1 at the site 200 from outside the site 200 through the environmental information. In other words, the disaster prevention support method further includes a status step of remotely managing or monitoring the installation status of the disaster prevention system 1 at the site 200 from outside the site 200. Therefore, the installation status of the disaster prevention system 1 can be easily grasped even from outside the site 200.

[0128] Environmental information obtained from the loaned disaster prevention system 1 can be collected and analyzed as big data. For example, the support unit 31 analyzes the cause of a fire based on the environmental information at the time of the fire. The support unit 31 also analyzes environmental information collected from multiple sites 200 and reflects the optimal installation location of the disaster prevention equipment 2 in a machine learning model.

[0129] Incidentally, the disaster prevention equipment 2 installed at the construction site 200 may have functions or specifications different from those installed in a normal building after construction. For example, the detector 21 (which may be the adapter 23 or the communication device 24) may periodically (for example, every few hours) output a voice message such as "Everything is normal" during a monitoring state in which no fire is detected. By periodically outputting a voice message, it is possible to give a sense of security to nearby on-site workers and also to alert them to the risk of fire.

[0130] Furthermore, taking into consideration that the detector 21 is installed in a noisy site 200, the volume of the alarm sound of the detector 21 may be set higher than the volume of a general detector.

[0131] It is preferable that the setting of the voice message (changing the message content, etc.) and the adjustment of the volume of the alarm sound can be performed by remote control from the support server 3, the monitoring server 70, the information terminal 71, etc. Furthermore, taking into account environmental information, it is also preferable that the adjustment of the sensitivity of the detector 21 for fire detection can be performed by remote control from the support server 3, the monitoring server 70, the information terminal 71, etc. The sensitivity may be set to switch between daytime and nighttime.

[0132] (2.6) Providing advisory information Incidentally, the activity area 300 of the construction site 200 may change in at least one of its shape and size depending on the progress of construction. FIG. 4 schematically shows how both the shape and size of the activity area 300 of the construction site 200 change over time. As shown in FIG. 4, for example, in the first week after construction begins, the assembly of steel frames for approximately half of the first floor is completed. In the second week, the assembly of steel frames for all of the first floor is completed. In the third week, the assembly of steel frames for approximately half of the second floor is completed. As the activity area 300 changes, temporary scaffolding, soundproofing and dustproofing sheets (not shown in FIG. 4), etc. are also installed.

[0133] Therefore, it may not be easy for the maintenance worker X11 who installs the disaster prevention system 1 to determine where to install which type of disaster prevention device 2. Particularly during the construction period when the walls and ceiling surfaces have not yet been completed, determining where to install the detectors 21 may not be as easy as when installing the detectors 21 in a building after construction in accordance with the Fire Service Act.

[0134] Therefore, the presentation unit 32 is configured to present advice information regarding the installation of the disaster prevention system 1 to the manager X1 (e.g., maintenance worker X11) of the site 200. In other words, the disaster prevention support method includes a presentation step of presenting advice information regarding the installation of the disaster prevention system 1 to the manager X1 of the site 200.

[0135] A maintenance worker X11 installs disaster prevention equipment 2 at one construction site 200 in stages according to the progress of construction. The support server 3 determines the number of stages to divide the installation work into, for example, based on BIM data, and generates installation schedule information. The support server 3 transmits an installation request to the maintenance server 4 or the presentation device 6, etc., according to the installation schedule information and loan information M1. The maintenance worker X11 performs the installation work according to the installation schedule information included in the installation request.

[0136] The installation schedule information may include, for example, information such as: first week (planned installation date: April 7th), installation location: first floor, type: detector (number of installations: 5), type: adapter (number of installations: 1), type: communication device (number of installations: 1), and type: lighting equipment (number of installations: 1). The installation schedule information may also include, for example, information such as: second week (planned installation date: April 14th), installation location: second floor, type: detector (number of installations: 5), and relocation: adapter. The "relocation" here refers to a case in which it is desirable to relocate adapter 23, which was originally installed on the first floor, to the second floor, because the shape and size of activity area 300 change as construction progresses and the wireless communication environment may also change.

[0137] The presentation unit 32 generates advice information based on the installation schedule information and the rental information M1, transmits it to the presentation device 6 carried by the maintenance worker X11, and causes it to be presented on the display unit 60 (see FIG. 5). Here, the advice information includes identification information for identifying the disaster prevention system 1 that is recommended for installation at the site 200. The identification information includes type information and number information of the disaster prevention devices 2. Note that the number information in the first information of the rental information M1 indicates the maximum number of devices that can be installed at the site 200, so the number of devices installed in the first week, second week, etc. in FIG. 4 may be less than the number indicated by the number information in the first information.

[0138] The advice information also includes location information for identifying the installation location of the disaster prevention system 1 in the site 200. As an example in this embodiment, as shown in Fig. 5, the presentation unit 32 displays, on the display unit 60 of the presentation device 6, two-dimensional map information 600 of the activity area 300 in which installation of the detector 21 is recommended. Then, the presentation unit 32 superimposes a marker P1 indicating the location of the recommended disaster prevention equipment 2 on the map information 600. In Fig. 5, for example, a floor plan of the first floor of the site 200 is schematically displayed on the display unit 60. In Fig. 5, the detector 21, the adapter 23, the lighting equipment 22, and the communication device 24 are each indicated by a different marker P1.

[0139] 5, the markers P1 of the adapter 23, the lighting devices 22, and the communication devices 24 are displayed near the entrance / exit on the map information 600. In other words, as an example, the presentation unit 32 advises that the adapter 23, the lighting devices 22, and the communication devices 24 be installed near the entrance / exit in consideration of the communication conditions, evacuation guidance, and the like.

[0140] The position information preferably includes information regarding the installation "orientation" of the disaster prevention equipment 2. For example, in the case of the detector 21, the position information preferably includes information that the front surface on which the operation buttons and the like are provided should be oriented vertically downward or horizontally.

[0141] In addition to the identification information and location information, the advice information also includes information regarding the location of the site 200 and the installation date (scheduled date). In FIG. 5, the character string information "First site" and "April 7th", which indicates the installation date, is displayed in a display area 601 in the upper left of the screen. By tapping the display area for "First site", the address of the first site 201 and the name of the contracted construction company 502 are displayed. Also in FIG. 5, the above-mentioned identification information is displayed in a display area 602 below the center of the screen.

[0142] When each marker P1 on the map information 600 is tapped, more detailed information showing the installation location is displayed as a pop-up. For example, as shown in FIG. 6A, a three-dimensional composite image is displayed showing the steel frame T1 to be installed and the detector 21 installed on the steel frame T1. The image of the steel frame T1 is acquired from the BIM data of the construction site 200. In this case, by displaying the three-dimensional composite image, information regarding the "orientation" of the installation of the disaster prevention equipment 2 can also be visually provided.

[0143] The maintenance worker X11 can check the advisory information by starting the presentation app on the presentation device 6. By presenting the advisory information in this way, the ease of installing the disaster prevention system is improved. At least a part of the advisory information may be shared not only with the maintenance worker X11 but also with a person of the construction company 502 (for example, the site supervisor X10, etc.).

[0144] The advice information is preferably information presented based on progress information that indicates the progress of construction (activity) during the construction period (activity period). Specifically, construction work may be delayed from the original building plan due to, for example, rain. Therefore, the support server 3 acquires construction progress information from a server (such as the monitoring server 70) of the construction company 502. The progress information may be information based on BIM data, or may be information input by the site supervisor X10 via the information terminal 71. The progress information may include, for example, information that the assembly of steel frames up to the third floor has been completed at this time.

[0145] The support server 3 updates the installation schedule information to the latest state based on the progress information during the construction period at the site 200. The presentation unit 32 generates advice information based on the updated installation schedule information and presents it on the display unit 60 of the presentation device 6. As a result, there is a high possibility that advice information appropriate for the actual progress status will be presented. Therefore, the maintenance worker X11 can more accurately know the next scheduled installation date at the same site 200 (for example, the scheduled installation date for the second floor).

[0146] When the disaster prevention devices 2 are installed in stages at the same site 200 on different days depending on the progress, the presentation unit 32 automatically determines and presents the optimal type and number of disaster prevention devices 2 for each scheduled installation date, for example, using a machine learning model trained by supervised learning. Furthermore, in this embodiment, for example, the maintenance worker X11 can start a presentation app on the presentation device 6 and input the type, number, etc. of disaster prevention devices 2 to be installed on a certain day.

[0147] Here, the presentation unit 32 of this embodiment is configured to present advisory information for the schedule of a specific day within the construction period (activity period). In other words, in the presentation step, advisory information for the schedule of a specific day within the construction period (activity period) is presented. The specific day can be any day within the construction period, and here it is assumed to be the planned installation date. Specifically, the advisory information has a chronological data structure constructed regarding the installation location of the recommended disaster prevention system 1, and includes map information 600 that takes into account the progress of construction as of the specific day (planned installation date). For example, the maintenance worker X11 can confirm the advisory information for the specified planned installation date by launching the presentation app, specifying the planned installation date, and inputting (schedule) the type and number of disaster prevention devices 2 to be installed, etc. The advisory information presents map information 600 based on the schedule (construction plan) and recommended specific information. Therefore, there is a high possibility that advisory information appropriate for the schedule of the specific day will be presented.

[0148] The support server 3 may present, as advice information, a method of maintenance such as cleaning for the disaster prevention equipment 2 from the presentation device 6. In this case, the maintenance worker X11 can clean the detector 21 while checking the advice information from the presentation device 6.

[0149] (2.7) Operation explanation The operation of the integrated system A1 will be briefly described below with reference to Figures 7 and 8. However, the order of the following operations is merely an example and is not particularly limited.

[0150] [Example 1] First, the procedure for installing the loaned disaster prevention system 1 at the first site 201 will be described with reference to the sequence diagram of FIG.

[0151] An information terminal 71 (or the monitoring server 70) carried by an employee of the construction company 502 transmits a request for lending the disaster prevention system 1 for the first site 201 to the support server 3 (step S1). The lending request includes, for example, BIM data related to the first site 201. Upon receiving the lending request, the support server 3 generates proposal information including the number and type of disaster prevention equipment 2 according to the scale of the first site 201, etc. (step S2: proposal processing), and transmits the proposal information to the information terminal 71 (step S3).

[0152] When the information terminal 71 receives the proposal information, it displays the proposal content on the screen (step S4). The information terminal 71 transmits response information to the proposal information in response to an operation input from the construction company 502 (step S5). If the received response information includes a positive response, the support server 3 generates rental information M1 (step S6). Furthermore, the support server 3 generates installation schedule information (step S7). Note that if the received response information includes a negative response, the support server 3 generates different proposal information and makes a new proposal.

[0153] The support server 3 sends an installation request to the maintenance server 4 according to the generated rental information M1 and installation schedule information (step S8), and requests the maintenance company 501 to install the disaster prevention system 1 at the first site 201. In response to the maintenance server 4 receiving the installation request, the maintenance worker X11 prepares the disaster prevention equipment 2 to be installed according to the installation schedule information, transports it to the first site 201, and performs the installation work.

[0154] Here, when performing installation work at the first site 201, the maintenance worker X11 may want advice regarding the installation of the disaster prevention system 1. In particular, since the activity area 300 of the first site 201 may change in shape and size depending on the progress of construction, the maintenance worker X11 may not be able to easily determine the installation location of each piece of disaster prevention equipment 2. Therefore, in response to an operation input from the maintenance worker X11, the presentation device 6 transmits an advice request (signal) requesting advice information to the support server 3 (step S9).

[0155] When the support server 3 receives the advice request, it generates advice information about the first site 201 (step S10) and transmits it to the presentation device 6 (step S11). As a result, the advice information is presented on the display unit 60 of the presentation device 6 (step S12), and the maintenance worker X11 can install the disaster prevention system 1 while referring to the advice information.

[0156] When the installation of the disaster prevention equipment 2 is completed, the maintenance worker X11 inputs that fact into the presentation device 6 (step S13: reception of installation completion). In response to the input, the presentation device 6 transmits an installation completion signal indicating the completion of installation to the support server 3 (step S14). For example, the maintenance worker X11 captures an image of the installed disaster prevention equipment 2 using a camera or the like attached to the presentation device 6. The presentation device 6 transmits the captured image together with the installation completion signal.

[0157] When the support server 3 receives the installation completion signal, it sets an installation completion flag in the rental information M1 to indicate that the planned installation of the disaster prevention equipment 2 at the first site 201 has been completed (step S15). The installation completion flag is preferably set when it is determined that the disaster prevention equipment 2 has been properly installed. This determination may be made automatically by the support server 3 by analyzing the image included in the installation completion signal, or may be made by a person (for example, a person in charge at the leasing company 500) directly checking the image.

[0158] Thereafter, when the loan period for the first site 201 is about to expire, the support server 3 transmits a collection request to the maintenance server 4 to request the maintenance company 501 to collect the disaster prevention system 1 from the first site 201 .

[0159] [Example 2] Next, the operation of the disaster prevention system 1 installed at the first site 201 will be described with reference to the sequence diagram of FIG.

[0160] The communication device 24 of the installed disaster prevention system 1 periodically transmits environmental information of the first site 201 obtained by a sensor or the like to the support server 3 (step S21).

[0161] For example, suppose a certain detector 21 (slave) detects a fire (step S22). The detector 21 (slave) issues an alarm sound and wirelessly transmits an interlocking signal to the detector 21 (parent) (step S23). Upon receiving the interlocking signal, the detector 21 (parent) issues an alarm sound and transmits the interlocking signal to other detectors 21 (slave) to interlock the alarms (step S24: execute interlocking).

[0162] Furthermore, the detector 21 (parent device) wirelessly transmits an alarm signal indicating that a fire has been detected to the adapter 23 (step S25).

[0163] Upon receiving the alarm signal, the adapter 23 turns on the notification contact (step S26). As a result, the lighting device 22 receives the notification output and turns on (step S27). Furthermore, upon receiving the notification output, the communication device 24 transmits the fire information to the information terminal 71 and external devices 5 such as the monitoring server 70 (step S26: external notification). A notification app is started in the information terminal 71, and information (such as an address) that can identify the first site 201 where the fire occurred is notified.

[0164] Furthermore, if the construction company 502 personnel or security guard X13 who rush to the scene after receiving the external notification checks the source of the fire and finds that it is a false alarm, they can press the operation button on the adapter 23 to stop the detector 21 from sounding an alarm and the lighting device 22 from turning on.

[0165] [advantage] As described in the above operation examples 1 and 2, according to this embodiment, the disaster prevention system 1 is loaned to establish a disaster prevention function at the site 200 during the activity period. Therefore, for the site 200 where strengthening disaster prevention measures is difficult to implement due to issues such as cost, the loaned disaster prevention system 1 is likely to resolve this. As a result, the disaster prevention support system 100 has the advantage of making it easier to implement strengthening disaster prevention measures at the site 200.

[0166] Furthermore, as described in the above operation example 1, according to this embodiment, advice information regarding the installation of the disaster prevention system 1 is presented. Therefore, it is more likely that the disaster prevention system 1 can be easily installed at the site 200 in the activity area 300, the shape and size of which may change depending on the progress of construction. As a result, the disaster prevention support system 100 has the advantage of being able to improve the ease of installing the disaster prevention system 1 at the site 200.

[0167] (3) 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. Furthermore, functions similar to those of the disaster prevention support system 100 according to the above embodiment may be embodied in a disaster prevention support method, a computer program, a non-transitory recording medium on which a computer program is recorded, or the like.

Furthermore, field-programmable gate arrays (FPGAs), which are programmable after the LSI is manufactured, or logic devices that allow the reconfiguration of internal connections or circuit partitions within the LSI, can also be used as processors. The electronic circuits may be integrated into one chip or distributed across multiple chips. The chips may be integrated into one device or 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.

[0170] Furthermore, it is not essential that the multiple functions of the disaster prevention support system 100 are concentrated in one housing. The components of the disaster prevention support system 100 may be distributed across multiple housings. Specifically, in the basic example, all of the multiple functions of the disaster prevention support system 100 are concentrated in one support server 3, but some or all of the functions may be distributed across the maintenance server 4, the monitoring server 70, the security server 8, etc.

[0171] Conversely, multiple functions of the disaster prevention support system 100 may be integrated into one housing, as in the basic example. Furthermore, at least some of the functions of the disaster prevention support system 100, for example, some of the functions of the disaster prevention support system 100 may be realized by the cloud (cloud computing) or the like.
