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 adjacent alarm device address 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. Then, the control circuit 1 drives the alarm sound control circuit 8 and the indicator lamp circuit 9 and causes the transmission / reception circuit 5 to output a state signal including battery state information.

  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 adjacent alarm device address setting switch 12 is configured by, for example, a rotary switch, and is a switch for setting an address of a fire alarm device set in a region adjacent to the region where the device is installed (for example, a room). The adjacent alarm device address setting switch 12 can set one or a plurality of arbitrary addresses. Address setting to the adjacent alarm device address setting switch 12 is performed by a user such as an installer or a resident of the fire alarm device 100.
The adjacent alarm device is an alarm device installed in a region adjacent to itself, and the user can determine which alarm device is the adjacent alarm device. For example, if there are multiple rooms each with one fire alarm, the alarms in the rooms next to each other may be “adjacent alarms”, or the alarms in the rooms opposite to each other may be “adjacent alarms”. It can also be set arbitrarily according to the structure of the building.

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 adjacent alarm device address setting switch 12, and the “alarm device address holding means” corresponds to the adjacent alarm device address 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 AD is added to other fire alarm devices (S110). The transmission source AD added here is the self-address AD201 stored in the storage element 11. In the first embodiment and the second embodiment to be described later, “AD” means an address.

  FIG. 6 is a flowchart showing the interlocking alarm monitoring process. In the interlock 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 source AD (ie, fire is detected) of the interlock control signal. After the delay time corresponding to the fire alarm) has elapsed, a process to output an interlocking alarm is performed. It is assumed that the address of one or more adjacent alarm devices is set in advance in the adjacent alarm device address setting switch 12.

First, it is determined whether an interlock control signal has been received from a fire alarm that has detected a fire (S121). When the interlock control signal is received, the transmission source AD added to the interlock control signal is stored (S122), and it is determined whether the stored transmission source AD is two or more different (S123). If two or more are different, an interlocking alarm is output (S131), and the timer 10 is cleared (S132). If there is one, it is determined whether or not the transmission source AD matches any one of the addresses set in the adjacent alarm device address setting switch 12 (S124). If they match, the transmission source of the interlock control signal, that is, the fire source is the adjacent alarm device. In this case, an interlock alarm is output (S131), and the timer 10 is cleared (S132).
If they do not match, it means that the source of the interlock control signal, that is, the fire source is not the adjacent alarm device, and in this case, human body detection is performed (S125). Then, for example, if a human body is detected, the delay time is set to 30 seconds (S126). If no human body is detected, the delay time is set to 60 seconds (S127), and the delay time timer count is started (S127). S128), the process is terminated.

If the interlock control signal has not been received in step S121, it is determined whether the interlock control signal has already been received (S129). As described above, since the transmission source AD is stored when the interlock control signal is received (S122), it can be determined whether or not the interlock control signal has been received based on whether or not this is stored. If the interlock control signal has been received, the timer count of the delay time may be started (S128) as described above. In this case, the delay time until the interlock alarm is output is waited. Even if the delay time has elapsed, an interlocking alarm is output and the timer 10 is cleared (S130, S131, S132). If the delay time has not elapsed, the process is terminated as it is.
In step S129, 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 showing an example of a dwelling unit in which the fire alarm 100 is installed, and shows an example of a building in which eight rooms from room 1 to room 8 are provided on a certain floor. In FIG. 7, “AD1” or the like shown in the fire alarm device means a self-address AD installed in the fire alarm device.
Taking the dwelling unit shown in FIG. 7 as an example, the operation when a fire occurs will be described with reference to FIG.

In this example, it is assumed that each fire alarm device has the addresses of the fire alarm devices in the left and right adjacent and front rooms set in the adjacent alarm device address setting switch 12 as the adjacent alarm device address. Specifically, the adjacent alarm device addresses installed in each fire alarm device are as follows.
Room 1: AD2, AD5
Room 2: AD1, AD3, AD6
Room 3: AD2, AD4, AD7
Room 4: AD3, AD8
Room 5: AD1, AD6
Room 6: AD2, AD5, AD7
Room 7: AD3, AD6, AD8
Room 8: AD4, AD7

First, a case where a fire occurs in the room 1 will be described as an example.
In this case, when the fire alarm in the room 1 detects a fire, it outputs a fire alarm 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 (S121) stores the transmission source AD added to the interlock control signal (S122), and the transmission source AD is set in its own adjacent alarm device address setting switch 12 It is determined whether or not it matches any of the addresses that have been set (S124).

  The fire alarm having the fire source room 1 as the adjacent alarm device, that is, the fire alarms installed in the room 2 and the room 5, immediately outputs a linked alarm without delay time (S131).

The fire alarm that does not use the room 1 as the fire source as an adjacent alarm, that is, the fire alarm installed in the room 3, the room 4, the room 6, the room 7, and the room 8, performs human body detection (S125). If a human body is detected, a delay time of 30 seconds is set (S126). If no human body is detected, a delay time of 60 seconds is set (S127), and a delay time timer count is started (S128).
When the delay time elapses (S130), an interlocking alarm is output and the timer 10 is cleared (S131, S132).

  Thus, when the fire alarm installed in the room adjacent to the fire alarm installed at the fire source receives the interlock control signal, it immediately outputs the interlock alarm by setting 0 seconds as the delay time. . In addition, a fire alarm installed in a non-adjacent room outputs an interlocking alarm after a lapse of a different delay time depending on whether a human body is detected.

Next, a case where a fire occurs in the room 2 after the fire has occurred in the room 1 and the interlock control signal is transmitted will be described as an example.
In this case, when the fire alarm in the room 2 detects a fire, it outputs a fire alarm and transmits an interlock control signal to the other fire alarms.
The fire alarm in each room that has received the interlock control signal (S121) stores the transmission source AD added to the interlock control signal (S122). Since two transmission sources AD, AD1 and AD2, are stored (A123), an interlocking alarm is immediately output (S131), and the timer 10 is cleared (S132).

  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 if the delay time due to the initial 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, since the transmission source AD is stored and only two or more different transmission source ADs are stored, the interlocking alarm is output regardless of the delay time (steps S123 and S131 in FIG. 6). The delay time is not canceled by receiving the interlock control signal transmitted from the same fire alarm twice or more.

  As described above, according to the fire alarm device according to the first embodiment, the delay time from when the interlock control signal is received until the interlock alarm is output is set according to whether or not it is adjacent to the fire source. Since it did in this way, an interlocking alarm can be outputted in steps according to the proximity degree with the fire origin. In addition, since all the fire alarms at the interlocking destination do not perform the interlocking alarm at the same time, it is possible to alleviate the congestion of the evacuation route due to residents or the like during evacuation.

  Also, for alarms that are not adjacent to the fire source, the delay time until the interlock alarm is output when a human body is detected is set short. For this reason, while being able to ease congestion of the evacuation route by the resident etc. at the time of evacuation, evacuation can be performed quickly.

  In addition, when the 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, it is possible to delay the interlocking alarm of the fire alarm installed in the area not adjacent to the fire source with a simple configuration in which only the adjacent alarm device address setting switch 12 is provided. For this reason, it is not necessary to provide a database or the like for holding a list of addresses of fire alarms provided in the building when performing a linked 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.
Of course, instead of providing the adjacent alarm device address setting switch 12, storage means for storing a database of address lists of adjacent alarm devices may be provided, and the same effect as described above can be obtained.

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, a fire alarm that detects a fire transmits an interlock control signal immediately to an adjacent alarm device and to a non-adjacent alarm device after a delay time elapses. An example of performing a delay will be described.
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. 8 is different from the above-described first embodiment in that it has an alarm final address setting switch 14 and is not provided with a human body detection sensor 13.

  The alarm device final address setting switch 14 is configured by, for example, a rotary switch, and is a switch for setting the final address of the building where the fire alarm device 100A is installed. In the second embodiment, it is assumed that the addresses assigned to each fire alarm are sequential numbers starting from 1, and the largest number among these addresses is the final address. Setting of the final address to the alarm device final address setting switch 14 is performed by a user such as an installer or a resident of the fire alarm device 100A.

  As shown in FIG. 9, in the storage element 11, a delay time storage area 202 is secured in addition to the self address AD201. The delay time storage area 202 is provided with an area for storing a predetermined delay time corresponding to addresses 1 to an arbitrary number. This delay time storage area 202 is rewritable, and stores a delay time until the interlock control signal is transmitted for each fire alarm device by a process described later.

  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 AD are added.

FIG. 11 is a flowchart showing the interlock control signal transmission process. It is assumed that the address of one or more adjacent alarm devices is set in advance in the adjacent alarm device address setting switch 12.
First, a delay time until the interlock control signal is transmitted is set for each address of the fire alarm device as the transmission destination (S141). Here, the fire alarm 100A sets the address of each fire alarm other than itself in the delay time storage means 202 by reading the address of the alarm final address setting switch 14 and the self address AD201 in the storage element 11. Next, for example, a delay time of 0 second (no delay) is set for its own adjacent alarm device, and a delay time of 30 seconds is set for other than the adjacent alarm device. Then, the set delay time is set in the delay time storage area 202 of the storage element 11 for each address of each fire alarm. The example of the memory element 11 shown in FIG. 11 shows an example of the fire alarm of the room 1 when a fire occurs in the room 1 of the building shown in FIG. For example, a delay time of 0 second is set for fire alarms (AD2, AD5) of 5, and a delay time of 30 seconds is set for other fire alarms (AD3, AD4, AD6, AD7, AD8). .

Next, the interlock control signal to which the transmission destination AD and the transmission source AD are added is transmitted to the adjacent alarm device (S142). The transmission destination AD to be added is the address of the adjacent alarm device set by the adjacent alarm device address setting switch 12. The transmission source AD is a self address AD201 stored in its own storage element 11. When there are a plurality of transmission destinations AD, a signal may be configured so that a plurality of transmission destinations AD can be specified by transmitting a single interlocking control signal, or each transmission destination AD is individually linked. A control signal may be transmitted.
As described above, in step S142, the interlocking control signal is immediately transmitted to the adjacent alarm device without setting the delay time by setting 0 seconds as the delay time.

Subsequently, the timer 10 starts the timer count of the delay time (S143), waits until the delay time of 30 seconds elapses, and when 30 seconds elapses (S144), for the fire alarm devices other than the adjacent alarm device, An interlock control signal to which the transmission source AD and the transmission destination AD are added is transmitted (S145). The transmission destination AD to be added is an address in which “30 seconds” is set as the delay time among the addresses stored in the delay time storage area 202.
As described above, the interlock control signal is transmitted to the fire alarm device other than the adjacent alarm device after the delay time of 30 seconds.
Then, the timer 10 is cleared and the process ends (S146).

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 or not an interlock control signal has been received (S151). If the interlock control signal has not been received, the process ends. When the interlock control signal is received, the transmission source AD is stored (S152), and it is determined whether there are two or more stored transmission source ADs (S153). If two or more are different, an interlocking alarm is output (S155), and the process is terminated. If there is one, it is determined whether or not the transmission destination AD added to the interlock control signal is the self AD, and if it is the self AD, an interlock alarm is output (S155). .

  As described above, according to the fire alarm device according to the second embodiment, when a fire is detected, the delay time elapses immediately for the adjacent alarm devices and for the fire alarm devices other than the adjacent alarm devices. An interlock control signal was sent later. The fire alarm that receives the interlock control signal outputs an interlock alarm when the interlock control signal is addressed to itself (addressed to the self address). For this reason, an interlocking alarm can be outputted in steps according to the degree of proximity to the fire source. 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 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, the interlocking alarm can be delayed with a simple configuration in which the adjacent alarm device address setting switch 12 and the alarm device final address setting switch 14 are provided. 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 user who attaches the fire alarm device is configured such that the addresses of the fire alarm devices are serial numbers and the final address is set by the alarm device final address setting switch 14. It enables to set the delay of interlocking alarm. However, the alarm final address setting switch 14 may not be provided, and a database of addresses of fire alarms installed in the building may be stored in advance.
In addition to the adjacent alarm device address setting switch 12, instead of providing an alarm device final address setting switch 14 or a database of addresses, a dedicated broadcast address for simultaneous transmission to all fire alarm devices is provided. The interlock control signal may be transmitted to this address after a predetermined delay time has elapsed. The fire alarm (fire alarm device other than the adjacent alarm device) that receives the interlock control signal addressed to the broadcast exclusive address judges that it is an interlock control signal addressed to itself (addressed to the self address) and outputs an interlock alarm. To do. Even if it does in this way, the effect similar to this Embodiment 2 can be acquired.

  In the first and second embodiments, the adjacent alarm device address setting switch 12 is set to the address of the fire alarm device adjacent to its own fire alarm device, but other than the adjacent fire alarm device is set. May be. For example, an arbitrary setting can be made according to the structure of the building and the situation of the user, such as setting the address of the fire alarm in the room of the user who needs time for evacuation to the adjacent alarm device address setting switch 12.

  In the first and second embodiments, whether or not a delay time until a linked alarm is output is determined depending on whether or not an address is set in the adjacent alarm device address setting switch 12. However, it may be distinguished whether the delay time is long or short, rather than whether or not the delay time is provided. For example, a fire alarm whose address is set in the adjacent alarm device address setting switch 12 may have a short delay time (for example, 15 seconds), and a non-set fire alarm device may have a long delay time (for example, 60 seconds). . Even in this case, the evacuation timing of the resident can be shifted, so that congestion of the evacuation route can be alleviated.

A plurality of types of switches corresponding to the adjacent alarm device address setting switch 12 described in the first and second embodiments may be provided, and the delay time may be determined for each switch. For example, a switch A for setting an adjacent alarm device and a switch B for setting an adjacent alarm device that is not adjacent to each other are provided. The switch A has a delay time of 0 seconds, the switch B has a delay time of 30 seconds, and the others have a delay time of 60 seconds. Set it as seconds. By doing so, it is possible to further delay the interlocking alarm step by step, which is useful for alleviating congestion on the evacuation route.
In the first embodiment, when the human body detection sensor 13 detects a human body, the adjacent alarm device that is not adjacent cancels or shortens the delay time (for example, 30 seconds is changed to 0 seconds or 15 seconds). The alarm device that is neither adjacent nor adjacent may be configured to reduce the delay time (for example, 60 seconds to 30 seconds).

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.
Moreover, this invention is applicable not only to a dwelling unit but to an apartment.
