Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the technology described in, for example, Patent Document 1, an operation of setting the time period for suppressing the alarm using a setting switch such as a DIP switch of a fire alarm provided on the ceiling or wall must be performed. Therefore, it may be difficult to set the time period for suppressing the alarm.

[0005] One object of the present invention is to enable a user to easily set the time period for suppressing the alarm.

Means for Solving the Problems

[0006] One aspect of the present invention provides an alarm system comprising: a detection unit for detecting an abnormality; a setting unit for setting a time period for suppressing alarms in accordance with the operation of a user terminal; and an alarm control unit for outputting an alarm sound from a sound output unit in response to the detection of the abnormality, wherein the alarm control unit reduces the volume of the alarm sound when it is output during the set time period compared to when it is output outside the time period. [Effects of the Invention]

[0007] According to the present invention, users can easily set the time period during which alarms are suppressed. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] 1. Structure Figure 1 shows an example of the configuration of the alarm system 1 according to this embodiment. In the alarm system 1, the user can set the time period during which the volume of the alarm sound output in response to various abnormal occurrences such as fires is changed. For example, if the alarm sound is output at a predetermined standard volume while the user is sleeping, the user may feel uncomfortable. Therefore, the user can set the system to lower the volume of the alarm sound output in response to various abnormal occurrences such as fires during such time periods. The alarm system 1 comprises a plurality of alarm devices 10, a user terminal 20, and a server device 30. These devices are connected via a network 40. The network 40 includes, for example, the Internet and a mobile communication network. The server device 30 and the network 40 may be connected by wire or wirelessly. Similarly, the plurality of alarm devices 10 may be connected by wire or wirelessly. In addition, although Figure 1 shows only one set of alarm devices 10 and one user terminal 20 installed in one building, the alarm system 1 may include multiple sets of alarm devices 10 and multiple user terminals 20 installed in multiple buildings.

[0010] The alarm device 10 is installed on the ceiling or wall of a building and detects a fire occurring in the building and outputs an alarm. The alarm device 10 is, for example, a residential fire alarm installed in a house. However, the alarm device 10 is not limited to a residential fire alarm, but may also be a fire alarm system installed in buildings such as commercial buildings or office buildings. The user terminal 20 is used by users entering and leaving the building to set a time period during which the alarm from the alarm device 10 is suppressed (hereinafter referred to as the "alarm suppression time period"). The user terminal 20 includes, for example, a smartphone, mobile phone, tablet device, or wearable device. However, the user terminal 20 is not limited to these devices, and may be any device used by a user. The server device 30 instructs the alarm device 10 to set the alarm suppression time period in response to the operation of the user terminal 20.

[0011] Figure 2 shows an example of the configuration of the alarm device 10. The alarm device 10 comprises a control unit 101, a storage unit 102, a communication unit 103, an operation unit 104, a display unit 105, a sound output unit 106, and a fire detection unit 107. The parts of the alarm device 10 are connected via a bus. The parts of the alarm device 10 may be connected by wire or wirelessly.

[0012] The control unit 101 controls each part of the alarm device 10 and performs various processes. The control unit 101 includes one or more processors, such as a CPU. The processor performs the above-mentioned control and processing by executing a program stored in the memory unit 102. The memory unit 102 stores various data used by the control unit 101. The memory unit 102 includes at least one of RAM, ROM, and EEPROM (registered trademark). The data stored in the memory unit 102 includes a program for realizing the functions of the alarm device 10, an identifier for the alarm device 10, and alarm sound data indicating an alarm sound. The communication unit 103 is a communication interface for communicating with the server device 30 via the network 40. The communication unit 103 includes, for example, a network adapter. The operation unit 104 accepts user operations and includes, for example, operation buttons. The display unit 105 displays various information and includes, for example, LEDs. The sound output unit 106 outputs various alarm sounds. These alarm sounds include alarm sounds that signal the occurrence of an abnormality such as a fire. The sound output unit 106 includes, for example, a speaker. The fire detection unit 107 detects a fire. The fire detection method is, for example, photoelectric or fixed temperature. However, the fire detection method is not limited to photoelectric or fixed temperature, and any method capable of detecting a fire may be used, such as an operating type, infrared type, ultraviolet type, or a combination thereof. The fire detection unit 107 is an example of a "detection unit" according to the present invention.

[0013] The control unit 101 of the alarm device 10 functions as a setting unit 111 and an alarm control unit 112. These functions are realized, for example, by the processor of the control unit 101 executing a program stored in the memory unit 102 to perform calculations or to control each part of the alarm device 10.

[0014] The setting unit 111 sets an alarm suppression time zone according to an instruction of the server device 30 in response to an operation of the user terminal 20. The alarm control unit 112 causes the sound output unit 106 to output an alarm sound corresponding to the alarm sound data stored in the storage unit 102 in response to the detection of a fire by the fire detection unit 107. When the alarm sound is output outside the alarm suppression time zone set by the setting unit 111, the alarm control unit 112 causes the sound output unit 106 to output the alarm sound at the reference volume. On the other hand, when the alarm sound is output during the alarm suppression time zone, the alarm control unit 112 causes the sound output unit 106 to output the alarm sound at a volume lower than the reference volume. In other words, when the alarm sound is output during the alarm suppression time zone, the alarm control unit 112 lowers the volume of the alarm sound compared to when it is output outside the alarm suppression time zone. The volume of the alarm sound output during the alarm suppression time zone is also predetermined like the reference volume. However, the volume of the alarm sound output during the alarm suppression time zone is preferably a volume lower than the reference volume but audible to the user. In addition, when the fire detection unit 107 detects a fire, the alarm control unit 112 causes the LED of the display unit 105 to blink or light up in addition to the output of the alarm sound.

[0015] FIG. 3 is a diagram showing an example of the configuration of the user terminal 20. The user terminal 20 includes a control unit 201, a storage unit 202, a communication unit 203, an operation unit 204, and a display unit 205. Each unit of the user terminal 20 is connected via a bus. The control unit 201, the storage unit 202, the communication unit 203, and the operation unit 204 are basically the same as the control unit 101, the storage unit 102, the communication unit 103, and the operation unit 104 of the above-described alarm device 10. However, the storage unit 202 stores a program for realizing the functions of the user terminal 20 and an identifier of the user terminal 20. The display unit 205 displays various types of information. The display unit 205 includes, for example, a liquid crystal display.

[0016] The control unit 201 of the user terminal 20 functions as a transmission unit 211. This function is realized, for example, by the processor of the control unit 201 executing a program stored in the storage unit 202 to perform calculations or controlling each part of the user terminal 20. When an operation for setting an alarm suppression time zone is performed by the user, the transmission unit 211 transmits operation information indicating this operation to the server device 30.

[0017] FIG. 4 is a diagram showing an example of the configuration of the server device 30. The server device 30 includes a control unit 301, a storage unit 302, and a communication unit 303. Each part of the server device 30 is connected via a bus. The control unit 301, the storage unit 302, and the communication unit 303 are basically the same as the control unit 101, the storage unit 102, and the communication unit 103 of the alarm device 10 described above. However, a program for realizing the functions of the server device 30 is stored in the storage unit 302. The storage unit 302 may further include a storage such as an HDD or an SSD.

[0018] The control unit 301 of the server device 30 functions as a setting instruction unit 311. This function is realized, for example, by the processor of the control unit 301 executing a program stored in the storage unit 302 to perform calculations or controlling each part of the server device 30. When operation information is received from the user terminal 20, the setting instruction unit 311 instructs the alarm device 10 to set an alarm suppression time zone according to the operation indicated by this operation information.

[0019] 2. Operations Figure 5 is a sequence diagram showing an example of the operation to set the alarm suppression period. This operation is initiated when the user requests the display of the alarm suppression period setting screen 250. In step S11, when the user makes this request by operating the operation unit 204 of the user terminal 20, the setting screen 250 is displayed on the display unit 205 of the user terminal 20. This setting screen 250 is a screen displayed by an application program stored in the storage unit 202, for example. Alternatively, the setting screen 250 may be a web screen provided by the server device 30 in response to a request from the user terminal 20 and displayed by a web browser stored in the storage unit 202. In step S12, the user uses the operation unit 204 of the user terminal 20 to set the alarm suppression period on the setting screen 250.

[0020] Figure 6 shows an example of the settings screen 250. The settings screen 250 includes input areas 251 and 252. Input area 251 accepts input for the alarm suppression period on weekdays. Input area 252 accepts input for the alarm suppression period on holidays. Holidays include, for example, Saturdays, Sundays, and public holidays. Weekdays are, for example, days other than holidays. The user operates the operation unit 204 of the user terminal 20 to input the weekday alarm suppression period in input area 251 and the holiday alarm suppression period in input area 252. For example, if the weekday alarm suppression period is from 21:00 to 7:00 the next day, the user enters the alarm suppression period of 21:00 to 7:00 the next day in input area 251. Also, if the holiday alarm suppression period is from 0:00 to 9:00, the user enters the alarm suppression period of 0:00 to 9:00 in input area 252.

[0021] Returning to Figure 5, in step S13, the transmission unit 211 of the user terminal 20 transmits operation information indicating the user's setting operation, along with the identifier of the user terminal 20, to the server device 30. This operation information includes the alarm suppression time periods for weekdays and holidays. In step S14, when the setting instruction unit 311 of the server device 30 receives the operation information and the identifier of the user terminal 20 from the user terminal 20, it transmits an instruction to the alarm device 10 to set the alarm suppression time period corresponding to the operation indicated by this operation information. For example, the storage unit 302 of the server device 30 stores in advance the identifier of the user terminal 20 used by the user, and the identifier and communication address of the alarm device 10 installed in the building that the user enters and exits. The setting instruction unit 311 of the server device 30 transmits an instruction to set the alarm suppression time period to the communication address of the alarm device 10 that is stored in association with the identifier of the user terminal 20 received from the user terminal 20. Alternatively, the user operates the user terminal 20 to input the identifier of the alarm device 10 installed in the building they enter and exit into the setting screen 250. The transmission unit 211 of the user terminal 20 transmits the operation information along with the identifier of the alarm device 10 to the server device 30. The storage unit 302 of the server device 30 stores the identifier of the alarm device 10 and its communication address in a pre-associated manner. The setting instruction unit 311 of the server device 30 sends an instruction to set the alarm suppression time period to the communication address of the alarm device 10 that is stored in association with the identifier of the alarm device 10 received from the user terminal 20.

[0022] In step S15, when the alarm suppression time period setting instruction is received from the server device 30, the setting unit 111 of the alarm device 10 sets the alarm suppression time period according to this setting instruction. Specifically, the setting unit 111 of the alarm device 10 stores the alarm suppression time period setting information 120 in the storage unit 102.

[0023] Figure 7 shows an example of the alarm suppression time period setting information 120. The setting information 120 includes the weekday alarm suppression time period and the holiday alarm suppression time period included in the setting instruction. This sets the weekday alarm suppression time period and the holiday alarm suppression time period. In the example shown in Figure 7, the weekday alarm suppression time period is 21:00-7:00 the next day, and the holiday alarm suppression time period is 0:00-9:00. This indicates that if an alarm sound is output during the weekday 21:00-7:00 the next day or holiday 0:00-9:00 time period, the alarm sound will be output at a volume lower than the standard volume, while if an alarm sound is output outside of these time periods, the alarm sound will be output at the standard volume.

[0024] Figure 8 is a flowchart showing an example of the alarm output operation of the alarm device 10. This operation is initiated when the alarm device 10 detects a fire. In step S21, if the fire detection unit 107 detects a fire (the determination in step S21 is YES), the process proceeds to step S22, where the alarm control unit 112 determines, based on the setting information 120 stored in the memory unit 102, whether the current date and time fall within the alarm suppression period. This current date and time is, for example, the date and time when the determination in step S22 is made. This current date and time can be considered as the date and time when the alarm sound is output.

[0025] For example, if the current time is 10:00 on a weekday, in the example shown in Figure 7, the weekday alarm suppression period is from 21:00 to 7:00 the next day, so the alarm control unit 112 determines that the current time does not fall within the alarm suppression period (the determination in step S22 is NO). In this case, the process proceeds to step S23, where the alarm control unit 112 outputs an alarm sound corresponding to the alarm sound data stored in the memory unit 102 at a standard volume from the sound output unit 106. This alarm sound is, for example, "Beep, whistle, whistle, fire, fire." On the other hand, if the current time is 22:00 on a weekday, in the example shown in Figure 7, the weekday alarm suppression period is from 21:00 to 7:00 the next day, so the alarm control unit 112 determines that the current time falls within the alarm suppression period (the determination in step S22 is YES). In this case, the process proceeds to step S24, where the alarm control unit 112 outputs an alarm sound corresponding to the alarm sound data stored in the memory unit 102 from the sound output unit 106 at a volume lower than the reference volume. This alarm sound is similar to the alarm sound output in step S23, for example, "Beep, whistle, whistle, fire, fire." However, the volume of the alarm sound output in step S24 is lower than the volume of the alarm sound output in step S23.

[0026] In the example shown in Figure 7, the alarm suppression period on weekdays is from 21:00 to 7:00 the following day, while the alarm suppression period on holidays is from 0:00 to 9:00. Therefore, the alarm suppression periods differ between weekdays and holidays. Consequently, in step S22 described above, if the current time is 8:00 on a weekday, the alarm sound is output at the standard volume, but if it is 8:00 on a holiday, the alarm sound is output at a volume lower than the standard volume. Also, if the current time is 22:00 on a weekday, the alarm sound is output at a volume lower than the standard volume, but if it is 22:00 on a holiday, the alarm sound is output at the standard volume.

[0027] According to the embodiment described above, the alarm suppression period can be set by operating the user terminal 20, so the user can easily set the alarm suppression period. Furthermore, more detailed settings can be made for the alarm suppression period, such as setting alarm suppression periods for weekdays and alarm suppression periods for holidays. If the alarm suppression period were to be set in response to operation of the alarm device 10, it would be necessary to provide a user interface such as a display on the alarm device 10 for setting the alarm suppression period, which would increase the size of the alarm device 10 and the cost of manufacturing the alarm device 10. However, in the embodiment described above, the alarm suppression period can be set by operating the user terminal 20, so it is possible to prevent the alarm device 10 from becoming larger and the cost of manufacturing the alarm device 10 from increasing.

[0028] 3. Variant The present invention is not limited to the embodiments described above, and may be implemented in the following modified forms. The following modified forms may be used individually or in combination of two or more.

[0029] Variation 1 In the embodiment described above, the alarm suppression period may be set in more detail. For example, the alarm suppression period may be set for each day of the week, each week, or each day. In addition, in the setting screen 250, it may also be possible to set the volume of the alarm sound output during the alarm suppression period, in addition to the alarm suppression period. Furthermore, multiple stages of alarm suppression period may be set. For example, the volume of the alarm sound output outside the alarm suppression period may be set to high, the volume of the alarm sound output during the first alarm suppression period may be set to medium, and the volume of the alarm sound output during the second alarm suppression period may be set to low. According to this modification, more detailed settings can be made for the alarm suppression period.

[0030] Variation 2 In the embodiments described above, the alarm sound whose volume is suppressed during the alarm suppression period is not limited to an alarm sound that signals the occurrence of a fire. This alarm sound can be any alarm sound that notifies the user of the occurrence of an event. For example, even if an alarm sound indicating an equipment abnormality such as a dead battery, soiling, or malfunction of the alarm 10 is output during the alarm suppression period, the volume of the alarm sound may be lowered compared to when it is output outside the alarm suppression period. In this case, the alarm 10 is equipped with an equipment abnormality detection unit that detects equipment abnormalities. The alarm control unit 112 outputs an alarm sound from the sound output unit 106 in response to the detection of equipment abnormalities by the equipment abnormality detection unit. This "equipment abnormality detection unit" is an example of a "detection unit" according to the present invention for detecting abnormalities in the alarm 10.

[0031] Variation 3 In the embodiment described above, the alarm suppression period may be set automatically based on information about the user's behavior obtained from the user terminal 20, without user intervention. Information about the user's behavior includes, for example, the operating mode and schedule information of the user terminal 20. However, information about the user's behavior is not limited to this information and may include other information obtainable from the user terminal 20.

[0032] In one example, the alarm suppression period is set based on the operating mode of the user terminal 20. In addition to the normal operating mode, the user terminal 20 has a sleep mode that is set during the user's sleeping hours. The time when sleep mode is set indicates the time when the user is asleep. Therefore, in this example, the alarm suppression period is set to the time when sleep mode is set. In this modified example, the memory unit 202 of the user terminal 20 stores a history of the times when sleep mode is set. The control unit 301 of the server device 30 further functions as an acquisition unit and a determination unit. The acquisition unit acquires a history of the times when sleep mode is set from the user terminal 20. The determination unit determines the alarm suppression period based on the history acquired by the acquisition unit. For example, if the typical value of the time when sleep mode is set on weekdays is 21:00-7:00 the next day, the determination unit determines 21:00-7:00 the next day as the weekday alarm suppression period. Furthermore, if the typical time for which the rest mode is set on holidays is 21:00-7:00 the following day, the determination unit will determine 21:00-7:00 the following day as the alarm suppression period on holidays. The setting instruction unit 311 then instructs the alarm device 10 to set the alarm suppression period determined by the determination unit.

[0033] In other examples, the alarm suppression period is set based on schedule information obtained from the user terminal 20. The schedule information may include the user's bedtime and wake-up time. The user's bedtime and wake-up time indicate the time the user is asleep. In this example, the alarm suppression period is set to the time from the user's bedtime to their wake-up time. In this case, the schedule information is obtained from the user terminal 20 in the same way as when the alarm suppression period is set based on the history of when the sleep mode is set, and a representative value of the time from the user's bedtime to their wake-up time is determined as the alarm suppression period.

[0034] According to this modified version, the alarm suppression period is set to suit the user's behavior without the user having to perform any operation to set the alarm suppression period. The automatic setting of the alarm suppression period described in this modified version may be used together with the manual setting of the alarm suppression period described in the above embodiment, or it may be used in place of the manual setting of the alarm suppression period.

[0035] Variation 4 In the embodiment described above, the alarm suppression period may be automatically set based on the user's behavior pattern recognized from information about user operations obtained from home appliances installed in the building, without user intervention. The home appliances are connected to the server device 30 via the network 40. Examples of home appliances include smart speakers and lighting. However, the home appliances are not limited to this example and may include other home appliances.

[0036] In this modified version, the control unit 301 of the server device 30 further functions as an acquisition unit, a recognition unit, and a determination unit. The acquisition unit acquires the user's operation history from home appliances. The recognition unit recognizes the user's behavior pattern based on the history acquired by the acquisition unit. For example, if a smart speaker is operated by the user's voice, it indicates that the user is awake. On the other hand, the time when the smart speaker is not operated may indicate that the user is asleep. Also, some smart speakers have functions that allow the user to operate room lighting fixtures by voice or have an alarm clock function. If the lighting fixtures are on, it indicates that the user is awake. On the other hand, the time when the lighting fixtures are off may indicate that the user is asleep. Furthermore, if an alarm clock is set, the user may go to sleep afterward. The user may wake up at the time the alarm set on the alarm clock is set. Therefore, the recognition unit recognizes the user's behavior pattern by analyzing the operation history of home appliances acquired by the acquisition unit. This behavior pattern includes the time when the user is asleep. Furthermore, the recognition unit may recognize the user's behavior patterns by using machine learning on the operation history acquired by the acquisition unit. The determination unit determines the time when the user is asleep, which is included in the user's behavior pattern recognized by the recognition unit, as the alarm suppression period. The setting instruction unit 311 then instructs the alarm device 10 to set the alarm suppression period determined by the determination unit.

[0037] According to this modified version, the alarm suppression period is set to suit the user's behavior without the user having to perform any operation to set the alarm suppression period. The automatic setting of the alarm suppression period described in this modified version may be used together with the manual setting of the alarm suppression period described in the above embodiment, or it may be used in place of the manual setting of the alarm suppression period.

[0038] Variation 5 In the embodiment described above, the server device 30 may set the alarm suppression period instead of the alarm device 10. In this modified example, the control unit 301 of the server device 30 functions as a setting unit 111 and an alarm control unit 112. The storage unit 302 of the server device 30 stores setting information 120 for the alarm device 10, associated with the identifier of the alarm device 10. When a fire is detected by the alarm device 10, it queries the server device 30 to determine whether or not it is within the alarm suppression period. The alarm control unit 112 of the server device 30 determines whether or not the current date and time fall within the alarm suppression period based on the setting information 120 stored in the storage unit 302. If the current date and time does not fall within the alarm suppression period, the alarm control unit 112 of the server device 30 instructs the alarm device 10 to output an alarm sound at a standard volume. On the other hand, if the current date and time falls within the alarm suppression period, the alarm control unit 112 of the server device 30 instructs the alarm device 10 to output an alarm sound at a volume lower than the standard volume. The sound output unit 106 of the alarm device 10 outputs an alarm sound according to the instructions of the server device 30. Even with this modified configuration, the volume of the alarm sound can be reduced when outputting the alarm sound during the alarm suppression period.

[0039] Variation 6 In the embodiment described above, the server device 30 is not necessarily required. In this modified example, the alarm device 10 and the user terminal 20 are connected via a network such as a wireless LAN. The transmission unit 211 of the user terminal 20 transmits operation information indicating the user's setting operation to the alarm device 10. Upon receiving the operation information from the user terminal 20, the setting unit 111 of the alarm device 10 sets the alarm suppression time period according to the operation indicated by this operation information. Even with the configuration according to this modified example, the alarm suppression time period can be easily set.

[0040] Variation 7 In the embodiments described above, the configuration of the alarm system 1 is not limited to the examples described above. The alarm system 1 may be configured to include one or more of the devices described above, or it may be configured to omit some of the devices. In one example, the alarm system 1 may be a disaster prevention system comprising a detector, a fire alarm receiver, user terminals 20, a server device 30, and emergency broadcasting equipment. In this case, the detector comprises the fire detection unit 107 described above. The control unit 101 of the server device 30 functions as the setting unit 111 described above and the alarm control unit 112. The fire alarm receiver and emergency broadcasting equipment comprises the sound output unit 106 described above. In another example, the alarm system 1 may be a local disaster prevention system comprising an alarm 10 installed in a certain area, a plurality of user terminals 20 used by a plurality of users in that area, and a server device 30.

[0041] Variation 8 In the embodiments described above, the operation of the alarm system 1 is not limited to the examples described above. The processing steps of the alarm system 1 may be rearranged as long as they do not contradict each other. In addition, some of the processing steps of the alarm system 1 may be omitted.

[0042] Modification 9 Another embodiment of the present invention may provide a method having processing steps performed in at least one of the alarm system 1, alarm device 10, user terminal 20, and server device 30. Yet another embodiment of the present invention may provide a program to be executed in each of the alarm device 10, user terminal 20, and server device 30. This program may be provided stored on a computer-readable recording medium or provided by download via the Internet or the like.

[0043] Variation 10 In the embodiments described above, the alarm 10 is not limited to detecting a fire and issuing an alarm, but may also detect and issue an alarm for abnormalities other than fire. For example, the alarm 10 may be a gas alarm that detects a gas leak and issues an alarm. Alternatively, the alarm 10 may be an alarm with a motion sensor that detects the intrusion of a suspicious person and issues an alarm. Both the gas alarm and the motion sensor are examples of the "detection unit" according to the present invention, as they detect abnormalities in the monitored area. In short, the alarm 10 may be any device that detects an abnormality and issues an alarm. The abnormality detected by the alarm 10 is not limited to a fire, but may be any abnormality such as a gas leak or the intrusion of a suspicious person.
