Description

  The present invention relates to an alarm device that performs an interlocking alarm among a plurality of devices.

Conventionally, “Parent and child alarm devices have a voltage level fluctuation that lowers the voltage level of the 2-wire signal line to a predetermined notification level when the fire detector detects a fire factor such as smoke or heat. A fire alarm system is known that includes a control circuit and a fire alarm control unit that outputs an alarm when it is determined that the voltage level generated in the two-wire signal line has dropped to a predetermined notification level (for example, Patent Document 1).
In recent years, there are also known devices in which each alarm device is wirelessly connected so that the alarm device can be easily installed in each room of an existing dwelling unit.

Japanese Patent Laying-Open No. 2005-339032 (page 3, FIG. 1)

  In the conventional fire alarm system, when a decrease in the voltage level of a signal line connected to another alarm device is determined, an interlocking alarm is performed. That is, a plurality of alarm devices simultaneously start a linked alarm. For this reason, if the users who were in each room who heard the interlocking alarm gathered together on the evacuation route to evacuate, it would be possible that evacuation would be hindered due to congestion.

  The present invention has been made to solve the above-described problems, and is an alarm that can alleviate congestion of evacuation routes by residents during evacuation in a general dwelling unit (or apartment) such as a detached house. A container is provided.

  The alarm device according to the present invention is an alarm device that transmits and receives an interlock control signal to and from other alarm devices. An abnormality alarm output means for outputting an abnormality alarm, an interlock control signal transmission means for transmitting an interlock control signal with its installation floor information added to another alarm device when an abnormality is detected, and from other alarm devices Based on the interlock control signal receiving means for receiving the interlock control signal, the installation floor information added to the received interlock control signal and the self-installation floor information, a predetermined delay time until the interlock alarm is output is set. A delay time setting means for performing the operation and an interlocking alarm output means for outputting the interlocking alarm after the predetermined delay time has elapsed.

  Further, in the alarm device, the delay time setting means sets a predetermined delay time corresponding to a difference between the value of the installation floor information added to the received interlock control signal and the value of the own installation floor information. Is.

  Further, in the alarm device, the delay time setting means cancels the setting of the delay time when receiving interlock control signals from two or more different alarm devices.

  Further, the alarm device includes a human body detection sensor for detecting a human body, and the delay time setting means detects the human body and the installation floor information added to the received interlock control signal. When the difference with the own floor information satisfies a predetermined condition, the set delay time is canceled or shortened.

  In addition, in the alarm device that transmits and receives the interlock control signal to and from other alarm devices, the installation floor information setting means for setting its own installation floor information, the top floor information holding means for holding the top floor information, When an abnormality is detected, an abnormality alarm output means for outputting an abnormality alarm, and when an abnormality is detected, an interlock control signal is transmitted to other alarm devices based on the top floor information and the own installation floor information. A delay time setting means for setting a predetermined delay time for each installation floor, and an interlocking control signal to which the installation floor information of the transmission destination is added after the delay time set for each installation floor has elapsed. , Interlock control signal transmitting means for transmitting to other alarm devices, interlock control signal receiving means for receiving interlock control signals from other alarm devices, installation floor information added to the received interlock control signal, and self When the installation floor information matches A linked alarm output means for outputting interlocking alarm, those having a.

  Further, in the alarm device, the delay time setting means sets a predetermined delay time according to a difference between the value of the own installation floor information and each installation floor information.

  Further, when the alarm device receives the interlock control signals from two or more different alarm devices, the interlock alarm output means includes the installation floor information added to the received interlock control signal and the own installation floor information. Regardless of whether they match, an interlocking alarm is output.

  Further, the alarm device includes a human body detection sensor for detecting a human body, and the interlock alarm output means detects the human body and the installation floor information added to the received interlock control signal. When the difference from the own floor information satisfies a predetermined condition, an interlocking alarm is output.

  According to the present invention, when an abnormality occurs in a general dwelling unit (or apartment) such as a detached house, the alarm device installed on each floor outputs a linked alarm after the delay time corresponding to the floor where the abnormality has occurred. . Since alarm devices installed on each floor do not perform interlocking alarms at the same time, congestion of evacuation routes by residents during evacuation can be alleviated.

  In addition, a predetermined delay time proportional to the difference between the floor where the abnormality occurred and the floor where it is installed is set. For this reason, for example, if the delay time is shortened for a room that is closer to the floor where the abnormality occurred, the interlocking alarm is output earlier for the lower floor of the floor where the abnormality occurs, the earlier the floor that takes time to evacuate. It is possible to relieve congestion of evacuation routes by residents during evacuation, and to evacuate quickly.

  Further, when the interlock control signals from two or more different alarm devices are received, the setting of the delay time is canceled. For this reason, when an abnormality expands and a plurality of alarm devices detect the abnormality, an interlocking alarm can be output without waiting for a delay time, and prompt evacuation can be promoted for residents and the like.

  In addition, a human body detection sensor is provided to detect a human body and to set a delay time when the difference between the installation floor information added to the received interlock control signal and the own installation floor information satisfies a predetermined condition. Release or shorten the delay time. For this reason, when there is a person, prompt evacuation can be promoted according to the difference between the floor where the abnormality has occurred and the floor on which it is installed.

Embodiment 1 FIG.
Hereinafter, in the first embodiment, a case where the present invention is applied to a fire alarm device that is driven by a battery and performs wireless communication will be described as an example.

  FIG. 1 is a functional block diagram showing the main configuration of the fire alarm according to Embodiment 1 of the present invention. In FIG. 1, a fire alarm 100 includes a control circuit 1, a battery 2, a power supply circuit 3, a battery voltage detection circuit 4, a transmission / reception circuit 5, an antenna 6, a fire detection circuit 7, an alarm sound control circuit 8, an indicator light circuit 9, An installation floor information setting switch 12 and a human body detection sensor 13 are provided.

  The battery 2 supplies DC power to the power supply circuit 3. The power supply circuit 3 controls the voltage of the battery 2 to a predetermined voltage and supplies it to the control circuit 1, the transmission / reception circuit 5, the fire detection circuit 7, the alarm sound control circuit 8, and the indicator lamp circuit 9.

  The battery voltage detection circuit 4 detects the voltage of the battery 2 applied to the power supply circuit 3 and outputs a battery voltage detection signal corresponding to the detected voltage to the control circuit 1. When the battery voltage detection circuit 4 detects that the remaining battery level has dropped or has fallen below the threshold for running out of the battery, the battery voltage detection circuit 4 outputs it to the control circuit 1, and the control circuit 1 displays a warning sound control circuit 8. The light circuit 9 is driven, and a state signal including state information about the battery exhaustion is output from the transmission / reception circuit 5.

  The fire detection circuit 7 detects a physical quantity or a physical change of an object to be detected such as smoke or heat based on a fire phenomenon, and outputs a signal corresponding to the detected content to the control circuit 1. The alarm sound control circuit 8 is a circuit that controls the sound (or sound) sounding operation by a buzzer / speaker or the like. The indicator lamp circuit 9 is a circuit that controls the lighting operation of indicator lamps such as light emitting diodes.

  The transmission / reception circuit 5 is connected to an antenna 6 for transmitting / receiving a radio signal, and includes a transmission circuit 51 and a reception circuit 52. The reception circuit 52 performs a reception sampling operation by performing a reception sampling operation by detecting a radio signal input from the antenna 6. The received signal is output to the control circuit 1. The transmission circuit 51 is controlled by the control circuit 1 to perform transmission processing of a signal such as an interlock control signal described later.

The control circuit 1 has a function of discriminating a fire state or the like based on the signal output from the fire detection circuit 7, performs necessary processing based on the signal received by the transmission / reception circuit 5, and transmits / receives as necessary. The circuit 5 is controlled to transmit various signals to other fire alarms.
When it is determined that the fire is in a fire state, the alarm sound control circuit 8 and the indicator light circuit 9 are controlled to give a fire alarm by sound and indicator light, and the transmitter circuit 51 is controlled to control another fire alarm device. A signal called an interlock control signal is transmitted.
Here, the interlock control signal is a signal for notifying other fire alarms that a fire has been detected and for causing a fire alarm (interlock alarm) from other fire alarms. In the transmission process of the interlock control signal, the control circuit 1 repeatedly transmits the interlock control signal for a predetermined period (for example, about 10 seconds). By doing in this way, the reception probability by the fire alarm on the receiving side can be increased.

  The timer 10 is provided with a time measuring device, starts measuring time according to an instruction from the control circuit 1, and outputs a time-up signal to the control circuit 1 when measuring a designated time.

  The storage element 11 is a nonvolatile memory such as an EEPROM, and stores programs executed by the control circuit 1 and various data. Further, as shown in FIG. 2, a self address AD201 is stored. This self address AD201 is set at the time of factory shipment or when installed in a dwelling unit or the like, and is an address unique to each fire alarm at least in an installation environment (for example, in a single house or apartment).

  The installation floor information setting switch 12 is composed of, for example, a rotary switch, and is a switch for setting the installation floor where the fire alarm 100 is installed. The installation floor information setting switch 12 sets its own installation floor by a user such as an installer of the fire alarm 100 or a resident.

The human body detection sensor 13 is a sensor that sends a human body detection signal to the control circuit 1 when a resident is detected.
In the first embodiment, the “abnormal alarm output means” and “interlocking alarm output means” of the present invention correspond to the control circuit 1, the fire detection circuit 7, and the alarm sound control circuit 8. The “interlocking control signal transmitting unit” corresponds to the control circuit 1 and the transmitting circuit 51, and the “interlocking control signal receiving unit” corresponds to the control circuit 1 and the receiving circuit 52. The “delay time setting means” corresponds to the control circuit 1 and the installation floor information setting switch 12. The “installation floor information setting means” corresponds to the installation floor information setting switch 12.

FIG. 3 is a flowchart showing the monitoring processing operation of the fire alarm 100 configured as described above.
First, it is determined whether or not the fire detection circuit 7 has detected a fire (S101). And when a fire is detected, the alarm sound control circuit 8 and the indicator light circuit 9 are controlled, and a fire alarm is given by sound and an indicator light (S102). After the fire alarm, an interlock control signal transmission process (S103) described later is performed.
If a fire is not detected (S101), a linked alarm monitoring process described later is performed (S104).
As described above, the fire alarm device 100 repeatedly performs the processing shown in FIG. 3 to perform fire monitoring of the area where the device is installed and monitoring of the interlocking alarm.

FIG. 4 is a flowchart showing the interlock control signal transmission process. The interlock control signal transmission process is a process of transmitting an interlock control signal for notifying a fire alarm installed in another room that a fire has been detected. FIG. 5 is a data configuration example of a signal transmitted in the interlock control signal transmission process.
As shown in FIG. 4, the fire alarm device 100 transmits an interlock control signal to which the transmission source FD and the transmission source AD are added to other fire alarm devices (S110). The transmission source FD added here is the own installation floor information FD set in the installation floor information setting switch 12. Further, the transmission source AD is the self address AD201 stored in the storage element 11. In Embodiment 1 and Embodiment 2 to be described later, “FD” means a value on the installation floor, and “AD” means an address.

  FIG. 6 is a flowchart showing the interlocking alarm monitoring process. In the interlocking alarm monitoring process in the first embodiment, the presence or absence of the interlock control signal is roughly monitored, and when the interlock control signal is received, the installation floor (that is, the fire of the interlock control signal) After the lapse of the delay time according to the floor), the interlock alarm is output. It is assumed that the installation floor information setting switch 12 is preset with its own installation floor information FD.

  First, it is determined whether or not the delay time has elapsed (S121). This delay time is the time counted by the timer 10 and is the time from when the interlock control signal is received until the interlock alarm is output. Therefore, this step S121 is an effective step after receiving the interlock control signal once (S122). Here, if the delay time has elapsed, an interlocking alarm is output and the timer 10 is cleared (S130). If the delay time has not elapsed, it is determined whether an interlock control signal has been received (S122).

  When the interlock control signal is received, the transmission source FD and the transmission source AD added to the interlock control signal are stored (S123), and it is determined whether the stored transmission source AD is two or more different (S123). S124). If there are two or more different, the delay time is canceled and the interlocking alarm is output immediately, and the timer 10 is cleared (S130). If there is one, the vertical relationship between the transmission source FD (that is, the floor where the fire has occurred) and the own FD (the installation floor of the self) is determined (S125). This can be determined by obtaining a difference between the value of the transmission source FD and the value of the self FD.

  In step S125, when the transmission source FD is equal to or less than the self-FD, that is, when the self is installed on the floor above the fire floor, the interlocking alarm is output immediately by setting the delay time to 0 seconds, and the timer 10 is cleared (S130).

  In step S125, if the transmission source FD is directly above the own FD, that is, if the self is set immediately below the fire floor, for example, 30 seconds is set as the delay time (S128). However, before that, human body detection is performed (S127), and when a human body is detected, 30 seconds as a delay time is canceled and an interlocking alarm is output immediately, and the timer 10 is cleared (S130). If no human body is detected, 30 seconds is set as the delay time (S128), the timer 10 starts counting the delay time (S129), and the process is terminated.

  In step S125, if the source FD is an upper floor excluding the floor directly above the own FD, that is, if the sender FD is installed on a floor lower than the fire floor and is not a floor immediately below, the delay time For example, 60 seconds is set (S126), the timer 10 starts the timer count of the delay time (S129), and the process is terminated.

If the interlock control signal has not been received in step S122, it is determined whether the interlock control signal has already been received (S131). As described above, when the interlock control signal is received, since the transmission source FD and the transmission source AD are stored (S123), it is determined whether or not the interlock control signal has been received depending on whether or not these are stored. Can do. If the interlock control signal has been received, the delay time timer count may be started (S129) as described above. In this case, the delay time until the interlock alarm is output is waited. It can be said that it is in a state. In this case, human body detection is performed. If a human body is detected and the transmission source FD is directly above itself (S132), an interlocking alarm is output and the timer 10 is cleared (S130). That is, even when waiting for the delay time to elapse, if a human body is detected when a fire has occurred immediately above itself, the delay time is canceled and an interlocking alarm is immediately issued. If no human body is detected, or if the transmission source FD is not directly above itself, the process is terminated.
In step S131, the process is also terminated when the interlock control signal has not been received (that is, when the interlock control signal has never been received).

FIG. 7 is a diagram illustrating an example of a dwelling unit in which the fire alarm 100 is installed, and illustrates an example of a four-story building provided with two rooms on each floor.
Taking the dwelling unit shown in FIG. 7 as an example, the operation when a fire occurs will be described with reference to FIG.

First, a case where a fire has occurred in the room 3-1 on the third floor will be described as an example.
In this case, the fire alarm in the room 3-1 outputs a fire alarm when a fire is detected, and transmits an interlock control signal to the fire alarm in another room.
The fire alarm in each room that has received the interlock control signal (S122) stores the transmission source FD and the transmission source AD added to the interlock control signal (S123), and determines the relationship between the transmission source FD and its own installation floor. to decide.

  Fire alarms installed on the third and higher floors, that is, the fire alarms in the room 3-2, the room 4-1, and the room 4-2, immediately output an interlocking alarm without delay ( S130).

The fire alarm installed on the floor immediately below the third floor, that is, the fire alarm in the room 2-1, the room 2-2 performs human body detection (S127), and if a human body is detected, the delay time is detected. The basic setting of 30 seconds is canceled and an interlocking alarm is output immediately (S130). If not detected, a delay time of 30 seconds is set (S128), and a timer count of the delay time is started (S129).
When the delay time elapses (S121), an interlocking alarm is output and the timer 10 is cleared (S130).
Further, the fire alarms in the room 2-1 and the room 2-2 can output a linked alarm immediately after releasing the delay time if a human body is detected (S132) even if the delay time is 30 seconds. Then, the timer 10 is cleared (S130).

The fire alarms installed on lower floors other than the third floor, which is the fire floor, that is, the fire alarms in the room 1-1 and the room 1-2, set a delay time of 60 seconds (S126), The timer count of the delay time is started (S129).
When the delay time elapses (S121), an interlocking alarm is output and the timer 10 is cleared (S130).

  In this way, the fire alarm installed on the fire floor or higher outputs an interlocking alarm as soon as it receives the interlocking control signal. The fire alarm installed below the fire floor outputs an interlocking alarm after the delay time corresponding to the installation floor has elapsed. On the floor immediately below, when a human body is detected, an interlocking alarm is immediately output without waiting for the delay time to elapse.

Next, a case where a fire occurs in the room 3-2 after a fire has occurred in the room 3-1 on the third floor and the interlock control signal has been transmitted will be described as an example.
In this case, the fire alarm in the room 3-2 outputs a fire alarm when a fire is detected (steps S101 and S102 in FIG. 3), and transmits an interlock control signal to the other fire alarms (FIG. 4). Step S110).
The fire alarm in each room that has received the interlock control signal (S122) stores the transmission source FD and the transmission source AD added to the interlock control signal (S123). The stored information is confirmed, and since two or more different senders AD are stored (S124), an interlocking alarm is output and the timer 10 is cleared (S130).

  As described above, when the interlock control signals transmitted from two or more different fire alarms are received, the interlock alarm is immediately output even when the delay time due to the first interlock control signal is waiting.

  As described above, the fire alarm that has detected a fire repeatedly transmits the interlock control signal for a predetermined period (for example, 10 seconds). Therefore, the fire alarm installed in another room may receive the interlock control signal issued from the same fire alarm multiple times. Even in such a case, the delay time is cleared only when the transmission source AD is stored and two or more different transmission source ADs are stored (steps S123 and S124 in FIG. 6). The delay time is not canceled by receiving the transmitted interlocking control signal twice or more.

  As described above, according to the fire alarm device according to the first embodiment, the delay time from the reception of the interlock control signal to the output of the interlock alarm is based on the floor where the fire occurred and the floor on which the fire is installed. Was set. For this reason, an interlocking alarm can be outputted in steps according to the positional relationship with the fire floor. Since all fire alarms at the interlocking destination do not perform the interlocking alarm at the same time, the congestion of the evacuation route by residents etc. during evacuation can be reduced.

  In addition, when the floor on which it is installed is lower than the fire floor, the delay time is shortened for rooms closer to the fire floor. For this reason, an interlocking warning is output earlier for lower floors than fire floors, so that the higher floors that take longer to evacuate can alleviate the congestion of evacuation routes by residents during evacuation and speed up evacuation. Can be done.

  In addition, when an interlock control signal transmitted from two or more different fire alarms is received, the interlock alarm is output immediately without waiting for the delay time. For this reason, when a fire spreads, a resident can be promptly evacuated.

  In addition, a human body detection sensor is provided, and when a human body is detected and the floor is immediately below the fire floor, the interlocking alarm is output immediately without waiting for the delay time. For this reason, when a user exists on the floor close to the fire floor, prompt evacuation can be promoted.

  In addition, with a simple configuration in which only the installation floor information setting switch 12 is provided, it is possible to delay the interlocking alarm (delay time setting) for each installation floor. For this reason, it is not necessary to provide a fire alarm database or the like provided in the building when performing the interlocking alarm. Therefore, even if the number of fire alarms to be installed increases or decreases, the operation can be continued and the usability is good.

Embodiment 2. FIG.
In the first embodiment described above, when a fire alarm device that detects a fire transmits a interlock control signal, the fire alarm device that has received the interlock control signal outputs an interlock alarm after a predetermined delay time has elapsed. In the second embodiment, an example will be described in which a fire alarm device that detects a fire transmits an interlock control signal after a delay time has elapsed for each installation floor of the destination fire alarm device. In other words, in the second embodiment, the transmission side alarm device delays the interlocking alarm by adjusting the transmission timing of the interlocking control signal.
Note that the basic configuration of the fire alarm 100A according to the second embodiment is the same as that of the first embodiment described above, and therefore, the differences will be mainly described.

FIG. 8 is a functional block diagram showing the main configuration of the fire alarm 100A according to the second embodiment. In FIG. 8, the point having the top floor information setting switch 14 is different from that of the first embodiment.
The top floor information setting switch 14 is configured by, for example, a rotary switch and is a switch for setting the top floor of the building where the fire alarm 100A is installed. The setting of the top floor to the top floor information setting switch 14 is performed by a user such as an installer or a resident of the fire alarm 100A.

Further, as shown in FIG. 9, a delay time storage area 202 is secured in the storage element 11 in addition to the self address AD201. The delay time storage area 202 is rewritable, and various types of information are stored by processing to be described later.
In the second embodiment, the “top floor information holding unit” of the present invention corresponds to the top floor information setting switch 14.

  The fire alarm 100A configured as described above performs the same monitoring processing operation as that of FIG. That is, by repeatedly executing the process shown in FIG. 3, fire monitoring and interlocking alarm monitoring are performed. However, the contents of the interlock control signal transmission process and the interlock alarm monitoring process are different and will be described below.

  FIG. 10 is a data configuration example of a signal to be transmitted in the interlock control signal transmission process according to the second embodiment. As shown in FIG. 10, the fire alarm device 100A transmits an interlock control signal to which a transmission source AD and a transmission destination FD are added. The transmission destination FD can be obtained based on the value of the top floor set in the top floor information setting switch 14.

FIG. 11 is a flowchart showing the interlock control signal transmission process. It is assumed that the installation floor information setting switch 12 is preset with its own installation floor information FD and the top floor information setting switch 14 is preset with the value of the top floor.
First, a delay time until the interlock control signal is transmitted is set for each installation floor of the fire alarm device as a transmission destination (S141). For example, in the case of an n-story building, delay times are set for the first to nth floors. Here, it is assumed that the delay time is 0 second (no delay) for the floors above the installation floor (fire floor), 30 seconds for the immediately lower floor, and 60 seconds for the lower floors other than the immediately lower floor. The set delay time is stored in the delay time storage area 202 of the storage element 11 for each installation floor. The example of the memory element 11 shown in FIG. 11 shows an example of a fire alarm in the room 3-1 when a fire occurs in the room 3-1 in FIG. 7 described above. The delay time is set to 0 seconds for the fourth floor, 30 seconds for the floor immediately below the fire floor (second floor), and 60 seconds for the lower floors (first floor) other than the floor immediately below.

Next, an interlock control signal to which the transmission destination FD and the transmission source AD are added is transmitted to the installation floors above the installation floor (S142). The transmission destination FD to be added here is a value equal to or higher than its own installation floor, and the transmission source AD is the self-address AD201 stored in the storage element 11. In addition, when there are a plurality of transmission destinations FD, a transmission signal may be configured so that a plurality of transmission destinations FD can be designated by one transmission of the interlock control signal. An interlocking control signal may be transmitted to.
As described above, the interlock control signal is immediately transmitted to the fire alarm installed on the fire floor or higher without delay time.

Subsequently, the timer 10 starts counting the delay time (S143), waits until the delay time of 30 seconds elapses, and when 30 seconds elapses (S144), it transmits to the floor immediately below its own installation floor. An interlock control signal with the destination FD and source AD added is transmitted (S145). The transmission destination FD to be added here is a value immediately below the floor on which it is installed, and the transmission source AD is the self address AD201.
As described above, the interlock control signal is transmitted to the fire alarm installed immediately below the fire floor after the delay time of 30 seconds.

Continuously, it waits until the delay time of 60 seconds elapses, and when 60 seconds elapse (S146), the interlock control in which the transmission destination FD and the transmission source AD are added to the lower floors except the floor immediately below the own installation floor. A signal is transmitted (S147). The transmission destination FD to be added here is a value of a lower floor excluding the floor immediately below the installation floor of itself, and the transmission source AD is a self address AD201.
As described above, the interlock control signal is transmitted after the delay time of 60 seconds to the fire alarm installed on the lower floor except for the floor immediately below the fire floor.
Then, the timer 10 is cleared and the process is terminated (S148).

Next, the interlocking alarm monitoring process will be described.
FIG. 12 is a flowchart showing the interlocking alarm monitoring process according to the second embodiment.
First, it is determined whether an interlock control signal has been received (S151). If received, the transmission source AD and the transmission destination FD are stored (S152), and it is determined whether the stored transmission source AD is two or more different (S153). If two or more are different, an interlocking alarm is output (S157), and the process is terminated. If there is one, it is determined whether the transmission source FD added to the interlock control signal is the self FD (S154).

In step S154, when the transmission destination FD added to the interlock control signal is the self FD set in the installation floor information setting switch 12, an interlock alarm is output (S157).
In step S154, if the transmission destination FD is not the own FD, that is, if it is not the interlocking control signal addressed to the installation floor, human body detection is performed (S155), and the human body is detected. If the FD is directly above the floor on which it is installed (when a fire has occurred on the floor directly above) (S156), an interlocking alarm is output (S157). If no human body is detected (S155), or if the transmission destination FD is an upper floor other than the floor directly above the installation floor, the process ends.

  If the interlock control signal has not been received in step S151, it is determined whether the interlock control signal has already been received (S159). As described above, when the interlock control signal is received, since the transmission source FD and the transmission source AD are stored (S152), it is determined whether or not the interlock control signal has been received depending on whether or not these are stored. Can do. When the interlock control signal has been received, human body detection is performed (S155), and when a human body is detected, the transmission destination FD is directly above its installation floor (when a fire has occurred on the upper floor) ) (S156), an interlocking alarm is output (S157). If no human body is detected (S155), or if the transmission destination FD is an upper floor other than the floor directly above the installation floor, the process ends.

As described above, according to the fire alarm device according to the second embodiment, when a fire is detected, a delay time is set for each installation floor of the destination fire alarm device. An interlock control signal is sent to each fire alarm. The fire alarm device that has received the interlock control signal outputs an interlock alarm when the interlock control signal is addressed to its own installation floor.
Also, for lower floors than fire floors, the closer to the fire floor, the shorter the delay time until the interlock control signal is transmitted.
In addition, when an interlock control signal transmitted from two or more different fire alarms is received, the interlock alarm is output immediately without waiting for the delay time.
In addition, a human body detection sensor is provided so that when a human body is detected and directly below the fire floor, an interlocking alarm is output even when the interlocking control signal addressed to the self is not received.
With such a configuration, it is possible to obtain the same effect as in the first embodiment.

In addition, with a simple configuration in which only the installation floor information setting switch 12 and the top floor information setting switch 14 are provided, it is possible to delay interlocking alarms (delay time setting) for each installation floor. For this reason, it is not necessary to provide a fire alarm database or the like provided in the building when performing the interlocking alarm. Therefore, even if the number of fire alarms to be installed increases or decreases, the operation can be continued and the usability is good.
In the second embodiment, the top floor information of the building is set by the top floor information setting switch 14 so that the user who installs the fire alarm can make the setting. However, the top floor information setting switch 14 may not be provided, but the top floor information may be stored in advance in storage means such as an EEPROM, and the “top floor information holding means” of the present invention may be configured by the storage means.

In the above description, the interlock alarm is output immediately on the floors above the fire floor without providing a delay time. This is because the upper floor of the fire floor is likely to be filled with smoke and toxic gas due to the fire, and is intended to prompt prompt evacuation by issuing an interlocking alarm as soon as possible. However, depending on the number of floors of the building and the fire floor, a delay time until the interlock alarm is output may be provided even on the upper floor of the fire floor. For example, the delay time may not be provided only for the fire floor and the floor immediately above it, and the delay time proportional to the difference from the fire floor may be provided for the other floors.
Moreover, the delay time (30 seconds, 60 seconds) demonstrated above is an example, and can be arbitrarily determined according to the number of floors of a building and an evacuation route.

In the above description, when a human body is detected and the floor on which the user is installed is directly under the fire floor, the interlock alarm is output by releasing the delay time without waiting for the delay time. For example, the delay time may be canceled in the same manner even when the installation floor is directly below the fire floor and further down there. In other words, when a human body is detected and the difference between the installed floor information added to the received interlock control signal and the own installed floor information satisfies a predetermined condition, the delay time may be canceled. Good. Furthermore, when a human body is detected, it may be determined not to cancel the delay time based on the difference between the installation floor information added to the received interlock control signal and the own installation floor information. Furthermore, instead of canceling the delay time, it may be shortened (for example, 30 seconds is set to 10 seconds). Even in this way, it is possible to prompt evacuation as quickly as possible while reducing congestion of the evacuation route during evacuation.
In the above explanation, even if a human body is detected, the delay time is set as it is if the installation floor is not directly under the fire floor, but the difference between the fire floor and the installation floor is Accordingly, the delay time can be shortened (for example, 60 seconds is set to 30 seconds). In this way, it is possible to prompt evacuation as quickly as possible when there is a user while reducing congestion of the evacuation route during evacuation.
In addition, based on the difference between the installation floor information added to the received interlock control signal and its own installation floor information, a floor that does not release the delay time, a floor that releases the delay time, and a floor that reduces the delay time. It is good also as a structure which can be set suitably.
Also, in the above description, the installation floor information setting switch 12 sets the fire alarm's own installation floor information so that the user who installs the fire alarm can make the setting. However, the installation floor information setting switch 12 is not provided, but the own installation floor information is stored in advance in storage means such as an EEPROM, and the “installation floor information setting means” of the present invention can be configured by the storage means.

  In the first embodiment, a delay time setting means is realized by the installation floor information setting switch 12 and the control circuit 1, and in the second embodiment, the installation floor information setting switch 12, the top floor information setting switch 14, and the control circuit 1 are used. The delay time setting means was configured. However, a database for delaying the interlocking alarm output or delaying the transmission of the interlocking control signal may be stored in advance in storage means such as an EEPROM. And the database to memorize | store may be a database based on installation floor information, and is good also as a database based on the address set individually to each fire alarm. Even if it does in this way, the effect similar to Embodiment 1, 2 can be acquired.

  In the above description, a four-story building has been described as an example, but the present invention can also be applied to a dwelling unit having an underground floor. Further, the present invention can be applied not only to dwelling units but also to apartments.

  Moreover, although the case where this invention was applied to the fire alarm device driven with a battery was demonstrated to the example in the said description, the supply method of a power supply is not limited to this. Moreover, although the case where signal transmission / reception is performed by wireless communication has been described as an example, the same effect can be obtained even by wired communication. In the above description, the fire alarm device has been described as an example, but the present invention can also be applied to an alarm device that detects abnormalities in other monitoring areas such as gas leakage.
