[0014] Preferred embodiments of the present disclosure will be described in detail below with reference to the drawings. Elements common to the embodiments described below are designated by the same reference numerals, and redundant descriptions of the common elements will be omitted. The following embodiment is merely one of various embodiments of the present disclosure. Various modifications can be made to the embodiment depending on the design, etc., as long as the object of the present disclosure can be achieved.

[0015] (Embodiment 1) (1) Overview First, an overview of an alarm linkage system 10 according to the first embodiment will be described with reference to FIGS.

[0016] As shown in FIG. 1, the alarm linkage system 10 according to the first embodiment includes a plurality of alarm systems 1 (three in the example of FIG. 1). Specifically, the alarm linkage system 10 according to the first embodiment includes a first alarm system 1a, a second alarm system 1b, and a third alarm system 1c. Each of the first alarm system 1a, the second alarm system 1b, and the third alarm system 1c is an alarm system 1 that detects a fire in a facility. The first alarm system 1a according to the first embodiment is provided in a first facility 100. The second alarm system 1b is provided in a second facility 200, and the third alarm system 1c is provided in a third facility 300.

[0017] In this disclosure, the term "facility" includes residential facilities used for residential purposes, as well as non-residential facilities such as stores (tenants), offices, welfare facilities, educational facilities, hospitals, and factories. Non-residential facilities also include restaurants, amusement parks, hotels, inns, kindergartens, nurseries, and community centers. In the first embodiment, the first facility 100, the second facility 200, and the third facility 300 are non-residential facilities such as office buildings. In the first embodiment, the first facility 100, the second facility 200, and the third facility 300 are located in close proximity to one another. In this disclosure, "vicinity" refers to the range within which the alarm system 1 can transmit fire information wirelessly without using another network. Furthermore, "vicinity" can also include the range within which the fire may spread and the range within which smoke or ash generated by the fire may reach if a fire breaks out at a facility.

[0018] As shown in Fig. 1, the first alarm system 1a includes a plurality of first sensors 4a. The plurality of first sensors 4a are installed in a first facility 100 (facility), which is a non-residential building, and are sensors 4 such as alarms that detect fires in the first facility 100 (facility). In the following description, each of the plurality of first sensors 4a may be referred to as a "first sensor 4a."

[0019] The second alarm system 1b (external system) also includes a plurality of second sensors 4c. The plurality of second sensors 4c are installed in a second facility 200 (facility) separate from the first facility 100, and are sensors 4 such as alarms that detect a fire in the second facility 200 (facility). In the following description, each of the plurality of second sensors 4c may be referred to as a "second sensor 4c."

[0020] 2, the first alarm system 1a includes an external communication unit 52 (first external communication unit). The external communication unit 52 transmits fire information relating to a fire detected by the first detector 4a to the second alarm system 1b, which is another alarm system 1 (external system), without going through another network such as the Internet.

[0021] "Fire information" in this disclosure may include facility information regarding the facility where the fire occurred, scale information regarding the scale of the fire, and meteorological information regarding the weather, such as wind direction and humidity.

[0022] The second alarm system 1b of the first embodiment has the same configuration as the first alarm system 1a. That is, the second alarm system 1b includes an external communication unit 52 (second external communication unit). The external communication unit 52 receives fire information related to a fire detected by the first detector 4a from the first alarm system 1a, which is an external system, without going through another network.

[0023] According to the alarm linkage system 10 of the first embodiment, the first alarm system 1a transmits fire information to the second alarm system 1b installed in the second facility 200 located near the first facility 100, thereby reducing damage in the vicinity of the fire site (the second facility 200). Furthermore, the first alarm system 1a transmits fire information directly to the second alarm system 1b without going through another network such as the Internet, which has the advantage of being less susceptible to communication failures in other networks. In other words, the first alarm system 1a can more reliably transmit fire information that needs to be promptly transmitted to the second alarm system 1b to the second alarm system 1b. Furthermore, the second alarm system 1b can reduce damage in the second facility 200 by issuing an alert regarding a fire that has occurred in, for example, the first facility 100.

[0024] (2)Details Next, details of the alarm linkage system 10 according to the first embodiment will be described with reference to FIGS.

[0025] (2.1) Alarm Linkage System As shown in FIG. 1, the alarm linkage system 10 includes a first alarm system 1a, a second alarm system 1b, and a third alarm system 1c.

[0026] (2.2) First Alarm System The first alarm system 1a according to the first embodiment is installed in a first facility 100. The first alarm system 1a includes a plurality of first sensors 4a, a plurality of first sensors 4b, a first master unit 5a, a first receiver 6a, and a first repeater 7a.

[0027] In the following description, each of the multiple first sensors 4b may be referred to as the "first sensor 4b." Also, the first sensor 4a or the first sensor 4b may be simply referred to as the "sensor 4." Also, the first master unit 5a may be simply referred to as the "master unit 5." Also, the first receiver 6a may be simply referred to as the "receiver 6." Also, the first repeater 7a may be simply referred to as the "repeater 7."

[0028] (2.2.1) Sensor The first detector 4a and the first detector 4b are detectors 4 included in the first alarm system 1a. The first detector 4a and the first detector 4b detect a fire in the first facility 100. The first detector 4a and the first detector 4b in the first embodiment function as slaves of the first master unit 5a. The first detector 4a communicates with the first master unit 5a using a wireless communication method conforming to standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low-power wireless (specified low-power wireless) that does not require a license. On the other hand, the first detector 4b is connected to the first master unit 5a via a wired connection and communicates with the first master unit 5a via the wired communication method. The first detector 4b may be connected to the first receiver 6a via a wired connection, thereby enabling communication with the first receiver 6a via the wired communication method.

[0029] As shown in FIG. 2, the detector 4 includes a communication unit 41, a control unit 42, a sensing unit 43, and a notification unit 44.

[0030] The sensor 4 includes, for example, a microcomputer having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the control unit 42. In other words, the control unit 42 is realized by a computer system having a processor and a memory. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or recorded on a non-transitory recording medium such as a memory card.

[0031] The communication unit 41 includes a communication interface configured to be able to communicate with other devices such as the parent unit 5. In this disclosure, "capable of communication" means being able to exchange information directly or indirectly via a network or a repeater, using an appropriate communication method such as wired communication or wireless communication.

[0032] The communication unit 41 of the first sensor 4a can communicate directly with the parent device 5 using a wireless communication method. Furthermore, the communication unit 41 of the first sensor 4a can communicate indirectly with the parent device 5 using a wireless communication method via the repeater 7.

[0033] The communication unit 41 of the first sensor 4b can communicate directly with the parent device 5 using a wired communication method. Furthermore, the communication unit 41 of the first sensor 4b can communicate indirectly with the parent device 5 using a wired communication method via other devices such as the first sensor 4b.

[0034] The communication unit 41 of the first sensor 4b may be configured to be able to communicate directly with the receiver 6 using a wired communication method. Furthermore, the communication unit 41 of the first sensor 4b may be configured to be able to communicate indirectly with the receiver 6 using a wired communication method via another device such as the first sensor 4b.

[0035] The communication unit 41 transmits the detection result of the detection unit 43 to the parent unit 5 together with information indicating the identifier of the device itself. The communication unit 41 also receives a notification instruction from the parent unit 5. The communication unit 41 of the first sensor 4b may be configured to transmit the detection result of the detection unit 43 to the receiver 6 together with information indicating the identifier of the device itself.

[0036] The sensor 43 has a function of detecting a fire (sensing function). Here, the sensor 43 is, for example, a photoelectric sensor that detects smoke. The sensor 43 includes, for example, a light-emitting element such as an LED (Light Emitting Diode) and a light-receiving element such as a photodiode.

[0037] The light-emitting unit and the light-receiving unit are arranged in the labyrinth of the housing of the device so that the light-receiving surface of the light-receiving unit is off the optical axis of the light emitted by the light-emitting unit. In the event of a fire, smoke can be introduced into the labyrinth through holes provided in the housing.

[0038] When there is no smoke in the labyrinth of the housing, the light emitted by the light-emitting unit hardly reaches the light-receiving surface of the light-receiving unit. On the other hand, when there is smoke in the labyrinth of the housing, the light emitted by the light-emitting unit is scattered by the smoke, and some of the scattered light reaches the light-receiving surface of the light-receiving unit. In other words, the sensing unit 43 receives the light emitted by the light-emitting unit that has been scattered by the smoke at the light-receiving unit.

[0039] The sensing unit 43 outputs to the control unit an electrical signal (sensing result) indicating a voltage level corresponding to the amount of light received by the light receiving unit.

[0040] The alarm unit 44 has a function of notifying the occurrence of a fire (an alarm function). The alarm unit 44 according to the first embodiment has a light-emitting unit such as an LED and a speaker, and issues an alarm by light and sound based on an instruction from the control unit 42.

[0041] The control unit 42 controls the communication unit 41 and the alarm unit 44. The control unit 42 controls the communication unit 41 so that the detection result of the fire by the detection unit 43 is transmitted to the master unit 5. The control unit 42 also controls the alarm unit 44 so that the alarm unit 44 issues an alarm based on an alarm instruction received from the master unit 5. The control unit 42 of the first sensor 4b may also control the communication unit 41 so that the detection result of the fire by the detection unit 43 is transmitted to the receiver 6. The control unit 42 of the first sensor 4b may also control the alarm unit 44 so that the alarm unit 44 issues an alarm based on an alarm instruction received from the receiver 6.

[0042] (2.2.2) Parent unit The first master unit 5a is the master unit 5 included in the first alarm system 1a. The master unit 5 transmits the detection results received from the detectors 4 to the receiver 6.

[0043] The base unit 5 includes a communication unit 51, an external communication unit 52 (first external communication unit), a control unit 53, and a storage unit .

[0044] The base unit 5 includes, for example, a microcomputer having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the control unit 53. In other words, the control unit 53 is realized by a computer system having a processor and a memory. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card.

[0045] The communication unit 51 includes a communication interface configured to be able to communicate with the sensor 4, the receiver 6, and the repeater .

[0046] The communication unit 51 receives the detection result directly from the detector 4 or indirectly via the repeater 7. The communication unit 51 also transmits the detection result received from the detector 4 to the receiver 6. The communication unit 51 receives a notification instruction from the receiver 6. The communication unit 51 also transmits the notification instruction received from the receiver 6 to the detector 4.

[0047] The external communication unit 52 is configured to be able to communicate with a plurality of alarm systems 1 (external systems) respectively installed in a plurality of other facilities without going through another network. The external communication unit 52 of the first alarm system 1a is configured to be able to communicate with a second alarm system 1b installed in a second facility 200 and a third alarm system 1c installed in a third facility 300. The external communication unit 52 has a transmission unit 521 and a reception unit 522.

[0048] The transmitting unit 521 transmits fire information to another alarm system 1 (external system) without going through another network, using a wireless communication method that complies with standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low-power radio (specified low-power radio) that does not require a license.

[0049] The transmitter 521 of the first alarm system 1a has a function of transmitting fire information about a fire detected by the first sensor 4a (4b) to at least one of the second alarm system 1b and the third alarm system 1c (external systems) without passing through another network. The transmitter 521 also transmits fire information received by the receiver 522 from an external system to another external system without passing through another network. For example, the transmitter 521 of the first alarm system 1a transmits fire information received by the receiver 522 from the second alarm system 1b equipped with the second sensor 4c (4d) to the third alarm system 1c, which is different from the second alarm system 1b equipped with the second sensor 4c (4d), without passing through another network. The transmitter 521 of the first alarm system 1a also transmits fire information received by the receiver 522 from the third alarm system 1c to the second alarm system 1b.

[0050] Furthermore, the transmitting unit 521 according to the first embodiment transmits fire information to another alarm system 1 (external system) based on the estimation result of an estimating unit 621 (described later) included in the receiver 6, without going through another network.

[0051] The first alarm system 1a of the first embodiment can reduce damage in the vicinity of the first facility 100 (third facility 300) by transmitting fire information received from another alarm system 1 (second alarm system 1b) to yet another alarm system 1 (third alarm system 1c). Furthermore, in the first alarm system 1a, the master unit 5 configured to be able to communicate with the receiver 6 has an external communication unit 52, so that fire information can be transmitted to the other alarm systems 1 stably and quickly.

[0052] The receiving unit 522 receives fire information about a fire detected by a detector 4 included in the other alarm system 1 from the other alarm system 1 without going through another network. The receiving unit 522 receives fire information from the other alarm system 1 without going through another network using a wireless communication method that complies with standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark) or low-power radio that does not require a license (specified low-power radio).

[0053] For example, the receiving unit 522 of the first alarm system 1a receives information about a fire detected by the second sensor 4c (4d) from the second alarm system 1b that includes the second sensor 4c (4d) without going through another network. Also, the receiving unit 522 of the first alarm system 1a may receive information about a fire detected by the second sensor 4c (4d) from the third alarm system 1c without going through another network.

[0054] The storage unit 54 is a semiconductor memory such as a ROM (Read Only Memory), a RAM (Random Access Memory), or an EEPROM (Electrically Erasable Programmable Read Only Memory). Note that the storage unit 54 is not limited to a semiconductor memory, and may be a hard disk drive or the like.

[0055] The memory unit 54 stores destination information of other alarm systems 1 (external systems) to which the external communication unit 52 (transmitter 521) transmits fire information. Since the memory unit 54 stores destination information, the external communication unit 52 can transmit fire information to a pre-registered alarm system 1 as the destination. The memory unit 54 also stores identifiers of each of the multiple sensors 4 included in the alarm system 1. Note that the external communication unit 52 may also employ a method of randomly transmitting fire information to multiple surrounding alarm systems 1 rather than to a pre-registered alarm system 1 as the destination.

[0056] The control unit 53 controls the communication unit 51. The control unit 53 controls the communication unit 51 so that it transmits the detection result received from the detector 4 to the receiver 6. The control unit 53 also controls the communication unit 51 so that it transmits the notification instruction received from the receiver 6 to the detector 4, which is a slave unit. The control unit 53 also controls the communication unit 51 so that it transmits fire information received from another alarm system 1 (external system) to the receiver 6.

[0057] The control unit 53 controls the external communication unit 52. Based on a communication instruction from the receiver 6, the control unit 53 controls the external communication unit 52 so that it transmits fire information detected by the detector 4 to another alarm system 1 (external system). Based on a communication instruction from the receiver 6, the control unit 53 also controls the external communication unit 52 so that it transmits fire information received from another alarm system 1 (for example, the second alarm system 1b) to another alarm system 1 (for example, the third alarm system 1c).

[0058] (2.2.3) Repeater The first repeater 7a is a repeater 7 included in the first alarm system 1a. The first repeater 7a of the first embodiment includes a communication interface configured to be able to communicate with the multiple first sensors 4a and the parent unit 5 via wireless communication. The first repeater 7a relays communication between the multiple first sensors 4a. The first repeater 7a also relays communication between the first sensor 4a and the parent unit 5.

[0059] (2.2.4) Receiver The first receiver 6a is the receiver 6 included in the first alarm system 1a. The receiver 6 receives the detection result of a fire detected by a sensor 4 in the alarm system 1 including the receiver 6. For example, the first receiver 6a receives the detection result of a fire detected by the first sensor 4a (4b). The receiver 6 of the first embodiment functions as a control device in the alarm system 1.

[0060] The receiver 6 includes a communication unit 61 , a control unit 62 , a storage unit 63 , a display unit 64 , and an operation unit 65 .

[0061] The receiver 6 includes, for example, a microcomputer having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the control unit 62. In other words, the control unit 62 is realized by a computer system having a processor and a memory. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or recorded on a non-transitory recording medium such as a memory card.

[0062] The communication unit 61 includes a communication interface configured to be able to communicate with the parent device 5. The communication unit 61 may also be configured to be able to communicate with the first sensor 4b connected by wire.

[0063] The storage unit 63 is a semiconductor memory such as a ROM, a RAM, or an EEPROM. Note that the storage unit 63 is not limited to a semiconductor memory, and may be a hard disk drive or the like.

[0064] The storage unit 63 of the first embodiment stores map information of the facility in which the alarm system 1 is installed, and map information of the vicinity of the facility in which the alarm system 1 is installed. The map information of the facility includes information on the installation location of each of the multiple sensors 4. The storage unit 63 also stores identifiers of each of the multiple sensors 4 included in the alarm system 1.

[0065] The display unit 64 has a display device such as a liquid crystal panel display. The display unit 64 is capable of displaying various information. For example, the display unit 64 can display information about the location where the detector 4 that transmitted the detection result to the receiver 6 is installed, information for selecting the detector 4 to which the notification instruction is to be transmitted, information about the elapsed time since the detector 4 first detected a fire, etc. The display unit 64 can also display information about the fire information received by the external communication unit 52 of the master unit 5.

[0066] The operation unit 65 accepts operation inputs by the user, such as various settings for the alarm system 1 and selection of the detector 4 to which an alarm instruction is to be sent. In the present disclosure, it is assumed that the user is a facility manager. The receiver 6 of the first embodiment is equipped with, for example, a touch panel type liquid crystal display as an operation display device including the display unit 64 and the operation unit 65. The operation display device functions as a user interface (GUI: Graphic User Interface).

[0067] The control unit 62 controls the communication unit 61, the display unit 64, and the operation unit 65. For example, the control unit 62 controls the communication unit 61 to transmit a notification instruction based on an operation input received by the operation unit 65 to the parent device 5. Note that the control unit 62 may also control the communication unit 61 to transmit a notification instruction based on an operation input received by the operation unit 65 to the first sensor 4b.

[0068] The control unit 62 of the first embodiment includes an estimation unit 621 and a determination unit 622.

[0069] The estimation unit 621 performs estimation processing to estimate the status of a fire based on the detection results of a fire detected by the sensors 4 in the alarm system 1 including the estimation unit 621. For example, the estimation unit 621 included in the first alarm system 1a estimates the status of a fire that has broken out in the first facility 100 based on the detection results of a fire detected by the first sensor 4a (4b). The estimation unit 621 may also estimate the status of a fire based on, in addition to the detection results output from the sensor 4, weather information obtainable from a server of a weather service provider that provides meteorological data on current weather and forecast data on future weather. The weather information may include information on the current and future weather (temperature, humidity, precipitation, wind direction, wind force, etc.) in the area including the facility where the fire is occurring.

[0070] The estimation unit 621 estimates the state of the fire based on the number of detection results received by the communication unit 61, the installation location of the detector 4 that transmitted the detection result, the elapsed time since the detector 4 first detected the fire, the concentration of smoke (magnitude of voltage level) detected by the detector 4, etc. The estimation unit 621 outputs the estimated result of the fire state to the determination unit 622.

[0071] The determination unit 622 makes a determination regarding the fire information. The determination unit 622 generates fire information based on the estimation result of the estimation unit 621. As described above, the fire information may include facility information regarding the facility where the fire occurred, scale information regarding the scale of the fire, and meteorological information.

[0072] Facility information may include information about the location of the facility, including the address of the facility where the fire occurred, information about the location of the fire within the facility, such as the room or floor where the fire occurred, information about the type (category) and name of the facility, and information about the storage (keeping) of hazardous materials under the Fire Service Act.

[0073] The decision unit 622 controls the communication unit 61 to send a transmission instruction to the master unit 5 to transmit the fire information generated based on the estimation result of the estimation unit 621 to another alarm system 1 (external system). The estimation result of the estimation unit 621 is based on the fire detection result. In other words, the receiver 6 causes the external communication unit 52 to transmit the fire information based on the fire detection result. In the first embodiment, the transmission instruction includes the fire information. When the master unit 5 receives the transmission instruction, the external communication unit 52 of the master unit 5 transmits the fire information based on the estimation result of the estimation unit 621 to the external system.

[0074] According to the alarm system 1 of the first embodiment, fire information is transmitted based on an instruction from the receiver 6 that receives the detection results from the detector 4, which makes it possible to reduce, for example, erroneous transmission of fire information. By transmitting the fire information generated based on the estimation result of the estimation unit 621 to an external system, it is possible to notify the external system of the status of the fire, such as the scale of the fire.

[0075] The scale information may include information about the range of the fire, the time the fire started, the time elapsed since the fire started, and the like.

[0076] The decision unit 622 decides to transmit the fire information to at least one of the plurality of external systems based on the estimation result of the estimation unit 621. The decision unit 622 of the first alarm system 1a decides to transmit the fire information to at least one of the second alarm system 1b and the third alarm system 1c.

[0077] The determination unit 622 controls the communication unit 61 to transmit a transmission instruction to the master unit 5 to transmit the fire information to another alarm system 1 (external system) that has been determined as the destination of the fire information. When the master unit 5 receives the transmission instruction, the external communication unit 52 of the master unit 5 transmits the fire information to at least one external system among the multiple external systems based on the transmission instruction. The transmission instruction is based on the estimation result of the estimation unit 621. In other words, the external communication unit 52 of the master unit 5 transmits the fire information to at least one external system among the multiple external systems based on the estimation result of the estimation unit 621.

[0078] According to the alarm system 1 of embodiment 1, based on the estimation result of the estimation unit 621, fire information can be transmitted to other alarm systems 1 installed in facilities that are estimated to be highly susceptible to the effects of a fire, for example.

[0079] Furthermore, when fire information is to be transmitted to two or more external systems among a plurality of external systems, the determination unit 622 determines the transmission order based on the estimation result of the estimation unit 621. For example, the determination unit 622 of the first alarm system 1a determines the transmission order for the second alarm system 1b to be 1 (first) and the transmission order for the third alarm system 1c to be 2 based on the estimation result of the estimation unit 621.

[0080] The determination unit 622 controls the communication unit 61 to transmit a transmission instruction to the master unit 5 to transmit the fire information to the alarm systems 1 determined as the destinations of the fire information in the transmission order determined by the determination unit 622. When the master unit 5 receives the transmission instruction, the external communication unit 52 of the master unit 5 transmits the fire information to two or more external systems in the order based on the transmission instruction when transmitting the fire information to two or more external systems among the multiple external systems. Since the transmission instruction is based on the estimation result of the estimation unit 621, the external communication unit 52 of the master unit 5 transmits the fire information to two or more external systems in the order based on the estimation result of the estimation unit 621 when transmitting the fire information to two or more external systems among the multiple external systems.

[0081] According to the alarm system 1 of embodiment 1, based on the estimation result of the estimation unit 621, fire information can be preferentially transmitted to other alarm systems 1 installed in facilities that are estimated to have a relatively high probability of being affected by the fire, for example.

[0082] (2.3) Secondary Alarm System As shown in FIG. 1, the second alarm system 1 b is installed in a second facility 200 .

[0083] The second alarm system 1b includes a plurality of second sensors 4c, a plurality of second sensors 4d, a second master unit 5b, a second receiver 6b, and a second repeater 7b. In the following description, each of the plurality of second sensors 4c may be referred to as a "second sensor 4c." Also, each of the plurality of second sensors 4d may be referred to as a "second sensor 4d."

[0084] The second alarm system 1b is the alarm system 1. That is, the second sensor 4c, the second sensor 4d, the second master unit 5b, the second receiver 6b, and the second repeater 7b provided in the second alarm system 1b correspond to the first sensor 4a, the first sensor 4b, the first master unit 5a, the first receiver 6a, and the first repeater 7a provided in the first alarm system 1a, respectively. Therefore, a detailed description of the second alarm system 1b will be omitted.

[0085] The second alarm system 1b transmits, for example, fire information received from the first alarm system 1a to the third alarm system 1c. The second alarm system 1b also determines the transmission order of fire information regarding a fire detected by the second detector 4c (4d) and transmits the information to the first alarm system 1a and the third alarm system 1c.

[0086] (2.4) Third Alarm System As shown in FIG. 1, the third alarm system 1 c is installed in a third facility 300 .

[0087] The third alarm system 1c includes a plurality of third sensors 4e, a plurality of third sensors 4f, a third master unit 5c, a third receiver 6c, and a third repeater 7c. In the following description, each of the plurality of third sensors 4e may be referred to as a "third sensor 4e." Also, each of the plurality of third sensors 4f may be referred to as a "third sensor 4f."

[0088] The third alarm system 1c is an alarm system 1. That is, the third sensor 4e, the third sensor 4f, the third master unit 5c, the third receiver 6c, and the third repeater 7c provided in the third alarm system 1c correspond to the first sensor 4a, the first sensor 4b, the first master unit 5a, the first receiver 6a, and the first repeater 7a provided in the first alarm system 1a, respectively. Therefore, a detailed description of the third alarm system 1c will be omitted.

[0089] The third alarm system 1c transmits, for example, fire information received from the first alarm system 1a to the second alarm system 1b. The third alarm system 1c also determines the transmission order of fire information regarding a fire detected by the third sensor 4e (4f) and transmits the information to the first alarm system 1a and the second alarm system 1b.

[0090] (3) Operation Next, an operation example of the alarm linkage system 10 according to the first embodiment will be described with reference to Fig. 3. Fig. 3 illustrates an example in which a fire breaks out in the first facility 100 in which the first alarm system 1a is installed.

[0091] First, the detector 4 of the first alarm system 1a detects a fire (S1). The first detector 4a (4b) that detected the fire transmits the detection result to the first master unit 5a (S2). The first master unit 5a receives the detection result and transmits it to the first receiver 6a (S3).

[0092] When the first receiver 6a receives the fire detection result, it performs an estimation process to estimate the status of the fire based on the detection result (S4).The first receiver 6a transmits a transmission instruction including the fire information to the first master unit 5a (S5).

[0093] The first master unit 5a, which has received the transmission instruction, transmits the fire information to another alarm system 1 (external system) based on the transmission instruction. In the example of Fig. 4, the transmission instruction is an instruction to transmit the fire information to the second alarm system 1b installed in the second facility 200 and the third alarm system 1c installed in the third facility 300. The transmission instruction is also an instruction to transmit the fire information to the second alarm system 1b and then the third alarm system 1c in that order.

[0094] The first master unit 5a of the first alarm system 1a transmits fire information to the second master unit 5b of the second alarm system 1b without going through any other network (S6). The second master unit 5b of the second alarm system 1b then receives the fire information without going through any other network (S7). The first master unit 5a of the first alarm system 1a then transmits the fire information to the third master unit 5c of the third alarm system 1c without going through any other network (S8). The third master unit 5c of the third alarm system 1c then receives the fire information without going through any other network (S9). In the second alarm system 1b and the third alarm system 1c, for example, an alert regarding a fire that has occurred in the first facility 100 is issued based on the received fire information.

[0095] It should be noted that the sequence diagram shown in FIG. 3 is merely an example, and the order of the processes may be changed as appropriate, and processes may be added or deleted as appropriate.

[0096] For example, the first alarm system 1a may simultaneously transmit fire information about a fire detected by the first detector 4a (4b) to the second alarm system 1b and the third alarm system 1c.

[0097] Furthermore, the first detector 4b that has detected a fire may transmit the detection result directly to the first receiver 6a by wired communication, without transmitting it to the first master unit 5a.

[0098] (4) Variations The first embodiment is merely one example of various embodiments of the present disclosure, and various modifications can be made to the first embodiment depending on the design and the like as long as the object of the present disclosure can be achieved.

[0099] Furthermore, functions equivalent to those of the alarm system 1 according to the first embodiment may be embodied as a linking method, a (computer) program, a non-transitory recording medium on which a program is recorded, or the like. A linking method according to one aspect is a method used in a first alarm system 1a (alarm system 1). The alarm system 1 includes a first sensor 4a (4b) installed in a first facility 100 that is a non-residential building and that detects fires. The linking method includes a transmitting step. In the transmitting step, fire information regarding a fire detected by the first sensor 4a (4b) is transmitted to an external system (second alarm system 1b) without going through another network. The external system includes a second sensor 4c (4d) installed in a second facility 200 that is different from the first facility 100 and that detects fires. Furthermore, a linking method according to one aspect is a method used in a second alarm system 1b (alarm system 1). The alarm system 1 includes a second sensor 4c (4d) installed in the second facility 200 that is a non-residential building and that detects fires. The linking method includes a receiving step. In the receiving step, fire information is received from the external system (first alarm system 1a) without going through another network. The fire information is information relating to a fire detected by a first sensor 4a (4b) that is installed in a first facility 100 separate from the second facility 200 and that detects fires. The external system is a system that includes the first sensor 4a (4b). A program according to one aspect is a program that causes one or more processors to execute the above-described cooperation method.

[0100] The alarm system 1 of the present disclosure includes, for example, a computer system. The computer system is primarily composed of a processor and memory as hardware. The functions of the alarm system 1 of the present disclosure are realized by the processor executing a program stored in the memory of the computer system. The program may be pre-stored in the memory of the computer system, provided via a telecommunications line, or provided in a non-transitory recording medium such as a memory card, optical disk, or hard disk drive that is readable 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 ICs and LSIs, are referred to by different names depending on the degree of integration, and include integrated circuits called system LSIs, very large-scale integrations (VLSIs), and ultra-large-scale integrations (ULSIs). Furthermore, field-programmable gate arrays (FPGAs), which are programmed after the LSI is manufactured, or logic devices that allow the reconfiguration of internal connections or internal circuit partitions of 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.

[0101] At least some of the functions of the alarm system 1 may be realized by the cloud (cloud computing) or the like.

[0102] Furthermore, the estimation unit 621 of the alarm system 1 may estimate the status of a fire that has broken out in a facility using a trained model generated by machine learning. The trained model is generated, for example, by supervised learning using a plurality of training data sets that indicate the relationship between the detection results of a fire detected by the detector 4 and the status of the fire. By inputting the detection results of a fire detected by the detector 4 into the trained model, the estimation unit 621 can obtain information indicating the status of the fire as the output of the trained model.

[0103] An example of the machine learning algorithm is a neural network. However, the machine learning algorithm is not limited to a neural network and may be, for example, an XGB (eXtreme Gradient Boosting) regression, a Random Forest, a decision tree, a Logistic Regression, a Support Vector Machine (SVM), a Naive Bayes classifier, or a k-nearest neighbors method. Furthermore, the machine learning algorithm may be, for example, a Gaussian Mixture Model (GMM), or a k-means clustering method.

[0104] In addition, the learning method is supervised learning as an example in the first embodiment. However, the learning method is not limited to supervised learning, and may be unsupervised learning or reinforcement learning.

[0105] Additionally, the trained model may be updated by performing additional training.

[0106] The entire first alarm system 1a does not have to be installed within the first facility 100. It is sufficient that at least the detector 4 included in the first alarm system 1a is installed within the first facility 100. Furthermore, the entire second alarm system 1b does not have to be installed within the second facility 200. It is sufficient that at least the detector 4 included in the second alarm system 1b is installed within the second facility 200.

[0107] The transmission route for fire information between multiple alarm systems 1 may be determined in advance. For example, a transmission route may be determined in advance such that fire information is transmitted from the first alarm system 1a to the second alarm system 1b, and then from the second alarm system 1b to the third alarm system 1c. Furthermore, the transmission route for fire information regarding a fire detected by a sensor 4 in one's own system may be different from the transmission route for fire information regarding a fire detected by a sensor 4 in another alarm system 1. Note that the destination information may include information regarding the transmission route.

[0108] The alarm system 1 may include a plurality of repeaters 7 .

[0109] In the first embodiment, the receiver 6 receives detection results from the detectors 4, estimates the status of the fire, and then determines the destinations to which the fire information will be sent and the order in which it will be sent. However, it is not essential that the receiver 6 estimates the status of the fire, that is, it is not essential that the receiver 6 has the estimation unit 621. For example, the receiver 6 may determine the destinations to which the fire information will be sent and send the fire information based on an operation input by a user who confirms the detection results received by the receiver 6.

[0110] In the first embodiment, the receiver 6 includes the estimation unit 621 and the determination unit 622. However, instead of the receiver 6, any of the detector 4, the master unit 5, and the repeater 7 may include the estimation unit 621 and the determination unit 622. For example, the first master unit 5a may include the estimation unit 621 and the determination unit 622. When the first master unit 5a includes the estimation unit 621, the first master unit 5a estimates the status of a fire that has occurred in the first facility 100 based on the detection result of the fire detected by the first detector 4a (4b). When the first master unit 5a includes the determination unit 622, the first master unit 5a transmits fire information generated based on the estimation result of the estimation unit 621 to another alarm system 1 (external system). In other words, the first master unit 5a causes the external communication unit 52 to transmit fire information based on the detection result of the fire. Since fire information is transmitted based on instructions from the master unit 5, which relays the results of fire detection by the first detector 4a (4b) to the receiver 6, it is possible to reduce, for example, erroneous transmission of fire information.

[0111] In the first alarm system 1a, the case where the first master unit 5a has the external communication unit 52 has been exemplified, but instead of the first master unit 5a, any one of the first sensor 4a, the first receiver 6a, and the first repeater 7a may have the external communication unit 52. Similarly, in the second alarm system 1b, the case where the second master unit 5b has the external communication unit 52 has been exemplified, but instead of the second master unit 5b, any one of the second sensor 4c, the second receiver 6b, and the second repeater 7b may have the external communication unit 52. Furthermore, which of the sensor 4, master unit 5, receiver 6, and repeater 7 has the external communication unit 52 may differ for each alarm system 1.

[0112] For example, if the first master unit 5a of the first alarm system 1a has an external communication unit 52, the first master unit 5a transmits fire information to the second alarm system 1b without going through another network. The second alarm system 1b may receive the fire information transmitted by the first master unit 5a using any of the second detector 4c, the second master unit 5b, the second receiver 6b, and the second repeater 7b. The second alarm system 1b, which has received the fire information using any of the second detector 4c, the second master unit 5b, the second receiver 6b, and the second repeater 7b, issues an alert regarding a fire that has occurred in the first facility 100, for example, based on an operational input from a user who has confirmed the received fire information.

[0113] Furthermore, if the first sensor 4a of the first alarm system 1a has an external communication unit 52, the first sensor 4a transmits fire information to the second alarm system 1b without going through another network. The second alarm system 1b may receive the fire information transmitted by the first sensor 4a using any of the second sensor 4c, the second master unit 5b, the second receiver 6b, and the second repeater 7b.

[0114] Furthermore, if the first repeater 7a of the first alarm system 1a has the external communication unit 52, the first repeater 7a transmits the fire information to the second alarm system 1b without going through another network. The second alarm system 1b may receive the fire information transmitted by the first repeater 7a at any of the second sensor 4c, the second master unit 5b, the second receiver 6b, and the second repeater 7b.

[0115] Furthermore, if the first receiver 6a of the first alarm system 1a has an external communication unit 52, the first receiver 6a transmits fire information to the second alarm system 1b without going through another network. The second alarm system 1b may receive the fire information transmitted by the first receiver 6a using any of the second sensor 4c, the second master unit 5b, the second receiver 6b, and the second repeater 7b. Note that, in a configuration in which the fire information is transmitted from the first receiver 6a to the second receiver 6b, the first receiver 6a and the second receiver 6b may be connected by a communication cable. In a configuration in which the first receiver 6a and the second receiver 6b are connected by a communication cable, the first receiver 6a may transmit fire information to the second receiver 6b using a wired communication method without going through another network.

[0116] (Embodiment 2) (1) Overview As shown in FIG. 4, the warning linkage system 10 of the second embodiment differs from the warning linkage system 10 of the first embodiment in that the second warning system 1b (warning system 1) is installed in a second facility 200, which is a residential facility.

[0117] (2) Details Next, the second alarm system 1b according to the second embodiment will be described in detail with reference to FIG.

[0118] (2.1) Secondary Alarm System The second alarm system 1b according to the second embodiment includes a plurality of second sensors 8, a control device 9, and a second repeater 7b.

[0119] (2.2) Sensor The multiple second sensors 8 include a parent second sensor 8a and multiple child second sensors 8b. In the following description, each of the multiple second sensors 8 may be referred to as a "second sensor 8." Also, each of the multiple second sensors 8b may be referred to as a "second sensor 8b."

[0120] (2.2.1) Child device The second sensor 8b includes a communication unit 81b, a control unit 82b, a sensing unit 83, and a notification unit 84.

[0121] The second sensor 8b includes, for example, a microcomputer having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the control unit 82b. In other words, the control unit 82b is realized by a computer system having a processor and a memory. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card.

[0122] The communication unit 81b can communicate with the second sensor 8a, which is the master device, directly using wireless communication. Furthermore, the communication unit 81b can communicate with the second sensor 8a, which is the master device, indirectly using wireless communication via the second repeater 7b (repeater 7).

[0123] The communication unit 81b transmits the detection result of the detection unit 83 together with information indicating the identifier of the own device to the second sensor 8a which is the master device. The communication unit 81b also receives a notification instruction from the second sensor 8a which is the master device.

[0124] The sensing unit 83 has a function of detecting a fire (sensing function). Here, the sensing unit 43 is, as an example, a photoelectric sensor that detects smoke. The configuration of the sensing unit 83 is the same as that of the sensing unit 43 described in the first embodiment, and therefore a description thereof will be omitted.

[0125] The notification unit 84 has a function of notifying the occurrence of a fire (notification function). The configuration of the notification unit 84 is the same as that of the notification unit 44 described in the first embodiment, and therefore a description thereof will be omitted.

[0126] The control unit 82b controls the communication unit 81b and the notification unit 84. The control unit 82b controls the communication unit 81b so as to transmit the result of fire detection by the detection unit 83 to the second detector 8a, which is the parent device. The control unit 82b also controls the notification unit 84 so as to make an alert based on an alert instruction received from the second detector 8a, which is the parent device.

[0127] (2.2.2) Parent unit The second sensor 8a, which is the master sensor, includes a communication unit 81a, a control unit 82a, a sensor unit 83, a notification unit 84, a storage unit 85, and an external communication unit 86.

[0128] The second sensor 8a includes, for example, a microcomputer having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the control unit 82a. In other words, the control unit 82a is realized by a computer system having a processor and a memory. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or recorded on a non-transitory recording medium such as a memory card.

[0129] The communication unit 81a can communicate directly with the control device 9 and the second sensor 8b, which is a slave device, using a wireless communication system. Furthermore, the communication unit 81a can communicate indirectly with the control device 9 and the second sensor 8b, which is a slave device, using a wireless communication system via the second repeater 7b.

[0130] The communication unit 81a receives the detection result directly from the second sensor 8b or indirectly via the second repeater 7b. The communication unit 81a also transmits the detection result received from the second sensor 8b to the control device 9. The communication unit 81a receives a notification instruction from the control device 9. The communication unit 81a also transmits the notification instruction received from the control device 9 to the second sensor 8b.

[0131] The external communication unit 86 is configured to be able to communicate with a plurality of alarm systems 1 (external systems) respectively installed in a plurality of other facilities without going through another network. The external communication unit 86 is configured to be able to communicate with the first alarm system 1a installed in the first facility 100 and the third alarm system 1c installed in the third facility 300.

[0132] The external communication unit 86 receives fire information regarding a fire detected by a detector 4 included in the other alarm system 1 from the other alarm system 1 without going through another network. The external communication unit 86 receives fire information from the other alarm system 1 without going through another network using a wireless communication method that complies with standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark) or low-power radio that does not require a license (specified low-power radio).

[0133] Furthermore, the external communication unit 86 transmits fire information received from an external system to another external system without going through another network. For example, the external communication unit 86 transmits fire information received from the first alarm system 1a to a third alarm system 1c separate from the first alarm system 1a without going through another network.

[0134] The storage unit 85 is a semiconductor memory such as a ROM, a RAM, or an EEPROM. Note that the storage unit 85 is not limited to a semiconductor memory, and may be a hard disk drive or the like.

[0135] The storage unit 85 stores destination information of other alarm systems 1 (external systems) to which fire information is transmitted by the external communication unit 86. The storage unit 85 also stores the identifiers of each of the plurality of second sensors 8b included in the second alarm system 1b.

[0136] The control unit 82a controls the communication unit 81a. The control unit 82a controls the communication unit 81a so that it transmits the detection result received from the second detector 8b to the control device 9. The control unit 82a also controls the communication unit 81a so that it transmits the notification instruction received from the control device 9 to the second detector 8b, which is a slave device. The control unit 82a also controls the communication unit 81a so that it transmits fire information received from another alarm system 1 (external system) to the control device 9.

[0137] The control unit 82a controls the external communication unit 86. For example, the control unit 82a controls the external communication unit 86 so that fire information received from another alarm system 1 (for example, the first alarm system 1a) is transmitted to another alarm system 1 (for example, the third alarm system 1c).

[0138] (2.3) Repeater The second repeater 7b is the repeater 7 included in the second alarm system 1b. The second repeater 7b of the second embodiment includes a communication interface configured to be able to communicate wirelessly with the second sensor 8a, which is the master device, and the plurality of second sensors 8b, which are slave devices. The second repeater 7b relays communication between the second sensor 8a and the second sensor 8b.

[0139] (2.4) Control device The control device 9 is, for example, a controller for a home energy management system (HEMS), and is capable of communicating with a plurality of devices provided in the second facility 200. The plurality of devices includes the above-described plurality of second sensors 8. The control device 9 is also capable of communicating with devices such as lighting devices and air conditioners provided in the second facility 200.

[0140] The control device 9 receives the result of the detection of the fire detected by the second detector 8 in the second alarm system 1b.

[0141] The control device 9 includes a communication unit 91 , a control unit 92 , and a storage unit 93 .

[0142] The control device 9 includes, for example, a microcomputer having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the control unit 92. In other words, the control unit 92 is realized by a computer system having a processor and a memory. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card.

[0143] The communication unit 91 includes a communication interface configured to be able to communicate with the second sensor 8a, which is the master device.

[0144] The storage unit 93 is a semiconductor memory such as a ROM, a RAM, or an EEPROM. Note that the storage unit 93 is not limited to a semiconductor memory, and may be a hard disk drive or the like.

[0145] The storage unit 93 stores the identifiers of the plurality of second sensors 8 included in the second alarm system 1b.

[0146] The control unit 92 controls the communication unit 91. For example, the control unit 92 controls the communication unit 91 so as to transmit a notification instruction to the second sensor 8a.

[0147] The second embodiment is merely one example of various embodiments of the present disclosure, and various modifications can be made to the second embodiment depending on the design and the like, as long as the object of the present disclosure can be achieved.

[0148] Although an example has been given in which the second sensor 8a, which is the parent device, has an external communication unit 86, instead of the second sensor 8a, any one of the second sensor 8b, which is the child device, the second repeater 7b, and the control device 9 may have the external communication unit 86.

[0149] The various configurations (including modified examples) described in the second embodiment can be adopted in appropriate combination with the various configurations (including modified examples) described in the first embodiment.

[0150] (summary) As described above, the alarm system according to the first aspect (first alarm system 1a) is an alarm system (1) including first sensors (4a; 4b). The first sensors (4a; 4b) are installed in a first facility (100) that is a non-residential building, and detect fires in the first facility (100). The alarm system (1) includes an external communication unit (52). The external communication unit (52) transmits fire information related to a fire detected by the first sensors (4a; 4b) to an external system (second alarm system 1b) without passing through another network. The external system includes second sensors (4c; 4d; 8). The second sensors (4c; 4d; 8) are installed in a second facility (200) separate from the first facility (100), and detect fires in the second facility (200).

[0151] According to this embodiment, the alarm system (first alarm system 1a) transmits fire information to the second alarm system (1b) installed in the second facility (200), thereby reducing damage in the vicinity of the fire site (second facility 200). In addition, the alarm system (1) transmits fire information directly to an external system without going through another network such as the Internet, which has the advantage of being less susceptible to communication failures in other networks.

[0152] The alarm system (first alarm system 1a) according to the second aspect is the same as the first aspect, but further includes an estimation unit (621). The estimation unit (621) estimates the state of the fire based on the detection result of the fire detected by the first sensors (4a; 4b). The external communication unit (52) is configured to be able to communicate with a plurality of external systems (second alarm system 1b; third alarm system 1c) provided in a plurality of second facilities (second facility 200; third facility 300), respectively, without going through another network. The external communication unit (52) transmits fire information to at least one of the plurality of external systems based on the estimation result of the estimation unit (621).

[0153] According to this aspect, based on the estimation result of the estimation unit (621), fire information can be transmitted to an external system (second alarm system 1b; third alarm system 1c) installed in a facility (second facility 200; third facility 300) that is estimated to be highly likely to be affected by the fire, for example.

[0154] In the alarm system according to the third aspect (first alarm system 1a), in the second aspect, when transmitting fire information to two or more external systems among a plurality of external systems (second alarm system 1b; third alarm system 1c), the external communication unit (52) transmits the fire information to each of the two or more external systems in an order based on the estimation result of the estimation unit (621).

[0155] According to this aspect, based on the estimation result of the estimation unit (621), fire information can be preferentially transmitted to external systems (second alarm system 1b; third alarm system 1c) installed in facilities (second facility 200; third facility 300) that are estimated to have a relatively high probability of being affected by the fire.

[0156] The alarm system according to the fourth aspect (first alarm system 1a) is the first to third aspect and further includes an estimation unit (621). The estimation unit (621) estimates the state of the fire based on the detection result of the fire detected by the first detector (4a; 4b). The external communication unit (52) transmits fire information based on the estimation result of the estimation unit (621) to an external system (second alarm system 1b; third alarm system 1c).

[0157] According to this aspect, by transmitting the fire information generated based on the estimation result of the estimation unit (621) to an external system (second alarm system 1b; third alarm system 1c), the external system can be notified of the fire situation, such as the scale of the fire.

[0158] An alarm system according to a fifth aspect (first alarm system 1a) is the alarm system according to any one of the first to fourth aspects, further including a receiver (6). The receiver (6) receives a result of fire detection detected by the first detector (4a; 4b). Based on the result of fire detection, the receiver (6) causes the external communication unit (52) to transmit fire information.

[0159] According to this aspect, fire information is transmitted based on an instruction from the receiver (6) that receives the detection result from the first detector (4a; 4b), so that it is possible to reduce, for example, erroneous transmission of fire information.

[0160] An alarm system according to a sixth aspect (first alarm system 1a) is the alarm system according to any one of the first to fourth aspects, further including a master unit (5). The master unit (5) transmits the detection results received from the first sensors (4a; 4b) to a receiver (6). The receiver (6) receives the detection results of the fire detected by the first sensors (4a; 4b). The master unit (5) causes the external communication unit (52) to transmit fire information based on the fire detection results.

[0161] According to this embodiment, fire information is transmitted based on instructions from the parent unit (5), which relays the results of fire detection by the first detector (4a; 4b) to the receiver (6), thereby reducing, for example, erroneous transmission of fire information.
