This corresponds to the LED 42 or the like. Moreover, the alerting | reporting method of the alerting | reporting part 40 is arbitrary, For example, you may change the kind of sound, a volume, etc. according to the interlocking | linkage origin alarm and the interlocking | linkage destination alarm which are mentioned later.

  The operation unit 50 is an operation unit that receives various operations on the residential alarm 10 and includes the alarm stop switch 51 described above. This alarm stop switch 51 is an alarm stop operation accepting means for accepting an alarm stop operation of the residential alarm 10.

  The battery power source 60 is a power supply unit that supplies power to the residential alarm 10. Although the specific kind of this battery power supply 60 is arbitrary, an alkaline dry battery, a lithium battery, etc. are used, for example.

  The control unit 70 is a control unit that performs various types of control in the residential alarm 10. The specific configuration of the control unit 70 is arbitrary. For example, the control unit 70 can be configured as a CPU (Central Processing Unit) that calls a program stored in the storage unit 80 and executes analysis.

  The control unit 70 includes an interlocking alarm processing unit 71, a recovery determination unit 72, and an alarm stop processing unit 73. The interlocking alarm processing unit 71 is an interlocking alarm processing unit that controls interlocking alarms between the dwelling alarm device 10 and the other dwelling alarm devices 10, and includes an interlocking source alarm processing unit 71a and a interlocking destination alarm processing unit 71b. Has been. When an abnormality is detected by the sensor unit 20, the interlocking source alarm processing unit 71 a outputs an alarm indicating the interlocking source (hereinafter referred to as an interlocking source alarm) by the speaker 41 and indicates a fire alert or the like by the transmission unit 31. This is an interlocking source alarm processing means for transmitting an alarm signal to another residential alarm device 10.

Thereby, the residence guard 10 can enable state transition control for a newly generated event. The method for storing the generated event in the state storage area 81b is arbitrary. For example, a method for sequentially storing the generated event and a method for overwriting the current generated event on the previous generated event are applicable.

(Regarding the processing operation of the home alarm)
Next, the processing operation of the residential alarm 10 will be described. As shown in FIG. 1, the home security device 10A is installed in the bedroom, the home security device 10B is installed in the living room, and the home security device 10C is installed in the kitchen. First, an abnormality is detected by the home security device 10A. Next, a case where an abnormality is detected by 10C will be described as an example. FIG. 4 is a flowchart showing the flow of the interlocking alarm process executed by the plurality of residential alarm devices 10A, 10B, and 10C. In the following description, “step” is abbreviated as “S”. Further, the step of the residential alarm 10A is abbreviated as “SA”, the step of the residential alarm 10B as “SB”, and the step of the residential alarm 10C as “SC”. In addition, events that occur during the operation of the home alarm devices 10A, 10B, and 10C are recorded in the state storage areas 81b of the storage units 80 by the control units 70.

  As shown in FIG. 4, when the sensor unit 20 of the home alarm device 10A detects an abnormality in the bedroom (SA1), an alarm signal is transmitted from the transmission unit 31 of the home alarm device 10A to the home alarm devices 10B and 10C. (SA2). This alarm signal is continuously transmitted while the sensor unit 20 of the home alarm device 10A detects an abnormality (hereinafter, the alarm signal of SC4 described later is also the same). The alarm signal includes a transmission source code 81 a stored in the memory 81 of the storage unit 80. Thus, when the home alarm devices 10B and 10C receive the alarm signal, it is possible to specify that the source of the alarm signal is the home alarm device 10A (hereinafter referred to as an SC4 alarm signal, SA6, which will be described later). The source code 81a is also included in the recovery signal of SC11 and the stop signal of SA10). Before and after SA2 or simultaneously with SA2, the home alarm device 10A outputs an interlocking source alarm through the speaker 41 to inform the user in the bedroom of the abnormality in the bedroom (SA3). The specific output method of the interlock source alarm is arbitrary. For example, in the case of the home guard 10A, the home guard of the interlock source, such as “Please confirm that the home guard in the bedroom was activated” is displayed. A voice message including the installation position of the device 10A is repeatedly output.

  On the other hand, when the receiving unit 32 of the home alarm devices 10B and 10C receives the alarm signal from the home alarm device 10A (SB1, SC1), the home alarm devices 10B and 10C are configured to sleep in the living room or the user in the kitchen. In order to notify the abnormality, an interlocking destination alarm is output by the speaker 41 (SB2, SC2). Although the operation method of the receiving unit 32 of the home alarm devices 10B and 10C is arbitrary, in order to reduce the power consumption of the battery power supply 60, for example, it is preferable to operate intermittently at a predetermined interval (hereinafter referred to as a housing). The receiving unit 32 of the alarm device 10A also operates in the same manner as the receiving units 32 of the residential alarm devices 10B and 10C). In addition, the specific output method of this interlocking destination alarm is arbitrary. For example, in the case of the house alarms 10B and 10C, it is interlocked as "Please check that the house alarm in the bedroom was activated". A voice message including the installation position of the original residence guard 10A is repeatedly output. In addition, the installation position of the interlocking home police 10A at this time is stored in advance in the storage unit 80 by associating the installation position of each residential policer 10 and the transmission source code 81 with each other. This can be done by referring to this information accordingly.

  Next, when the sensor unit 20 of the home alarm device 10C detects an abnormality in the kitchen (SC3), an alarm signal is transmitted from the transmission unit 31 of the home alarm device 10C to the home alarm devices 10A and 10B (SC4). At the same time, the interlocking source alarm is output by the speaker 41 in the residential alarm 10C (SC5). Here, in the residential alarm 10C, the interlocking destination alarm is output in the process of SC2, but in order to give priority to notifying the user in the kitchen of the abnormality of the kitchen, the interlocking is performed by the speaker 41. Only the original alarm is output. Therefore, for example, in the home alarm 10C, the voice message up to that point is “Installation of the home alarm 10C that became the interlocking source, such as“ Please confirm that the home alarm in the kitchen was activated ”. Is switched to a voice message containing

  On the other hand, in the house alarm devices 10A and 10B, the receiving unit 32 receives an alarm signal from the house alarm device 10C (SA4 and SB3). Here, the home alarm device 10A is in a state in which an interlocking destination alarm can be output, but the interlocking source alarm is continuously output after the processing of SA3, and the bedroom alarm is issued to the user in the bedroom. Since it is preferable to give priority to notifying the abnormality, the interlocking source alarm is continuously output by the speaker 41 (SA5). Further, since the interlocking destination alarm is output in the process of SB2 in the home alarm device 10B, the interlocking destination alarm is subsequently output (SB4). Although the specific output method of this interlocking destination alarm is arbitrary, in order to notify the user in the living room of the abnormality of the bedroom and the kitchen, for example, in the housing alarm device 10B, “Woo Woo bedroom housing alarm device” ”And” Woooo The kitchen resident alarm has been activated, please confirm ”, and the voice message including the installation location of the resident alarm 10A that is the linking source The voice message including the installation position of the original residence guard 10C is alternately and repeatedly output.

  Next, when the sensor unit 20 of the home alarm device 10A no longer detects an abnormality in the bedroom (SA6), the home alarm device 10A transmits to stop the interlocking destination alarm for the home alarm devices 10B and 10C. The restoration signal is transmitted by the unit 31 (SA7), and the interlocking source alarm is stopped. However, since the receiving unit 32 continues to receive the alarm signal from the residential alarm 10C in the residential alarm device 10A after the processing of SA4, the interlocking destination alarm is output by the speaker 41 (SA8). For example, in the home alarm 10A, the voice message up to that point included the installation position of the home alarm 10C that is the interlocking source, such as “Please check that the home alarm in the kitchen was activated”. Switch to voice message and output repeatedly.

  On the other hand, the receiving unit 32 of the home alarm devices 10B and 10C receives the recovery signal (SB5, SC6), but in the home alarm device 10B, the receiving unit 32 continues the alarm signal from the home alarm device 10C after the processing of SB3. Therefore, the interlocking destination alarm is continuously output by the speaker 41 (SB6). Further, in the residential alarm 10C, as in the process of SC5, the interlocking source alarm is continuously output by the speaker 41 (SC7).

  Subsequently, when a user in the bedroom operates the alarm stop switch 51 of the residence guard 10A (SA9), a stop signal is transmitted from the transmission unit 31 (SA10), and the interlocking destination alert is issued. Is stopped (SA11). In addition, although it is supposed here that the interlocking destination alarm is stopped, at this point, since the home guard 10C that is the interlocking source still remains, the home guard 10 that is the interlocking source in this way, When at least one residential alarm 10 that has not received an alarm stop operation by the alarm stop switch 51 remains, the interlocking destination alarm may be continued.

  On the other hand, when the receiving unit 32 of the home alarm devices 10B and 10C receives the stop signal from the home alarm device 10A (SB7, SC8), in the home alarm device 10B, when the interlocking destination alarm is stopped, the user in the living room is notified. On the other hand, since it becomes impossible to notify the abnormality of the kitchen, the interlocking destination alarm is continuously output by the speaker 41 (SB8). That is, when the home alarm device 10B receives the stop signal, there remains even one home alarm device 10 that is the home alarm device 10 that is the interlocking source and that has not received the alarm stop operation by the alarm stop switch 51. If it remains, the interlocking destination alarm is continued. In addition, when the interlocking source alarm is stopped in the residential alarm device 10C, it becomes impossible to notify the user in the kitchen of the abnormality of the kitchen, so the interlocking source alarm is continuously output by the speaker 41 (SC9). .

  Thereafter, when the sensor unit 20 of the home alarm device 10C does not detect any abnormalities in the kitchen (SC10), the home alarm device 10C transmits the stop alarm to the home alarm devices 10A and 10B. The restoration signal is transmitted by the unit 31 (SC11), and the interlocking source alarm is stopped (SC12).

  On the other hand, when the receiving unit 32 of the home alarm devices 10A and 10B receives the recovery signal (SA12, SB9), the interlocking destination alarm is stopped in the home alarm device 10A following the processing of SA11 (SA13). Moreover, in the house alarm device 10B, the interlocking destination alarm is stopped (SB10). That is, when the home alarm device 10B receives the stop signal, there remains even one home alarm device 10 that is the home alarm device 10 that is the interlocking source and that has not received the alarm stop operation by the alarm stop switch 51. If it does not remain, the interlocking destination alarm is stopped. This completes the interlocking process.

(Fire monitoring process)
Next, a fire monitoring process executed by the home alarm device 10 when any of the home alarm devices 10 belonging to the alarm system 1 detects an abnormality such as a fire will be described. FIG. 5 is a flowchart showing the fire monitoring process of each residential alarm 10. In the following processing, it is assumed that the power supply of these residential alarms 10 is always turned on, and that it is possible to always execute each processing in accordance with the program stored in the storage unit 80, except for specially noted subjects. Then, the process is performed by the control unit 70.

  First, in order to determine whether or not an abnormality has been detected in the room in which the home alarm device 10 is installed, the control unit 70 causes the sensor unit 20 to perform a monitoring operation on the room (SD1). In the subsequent processing, the interlocking source alarm process (the process of SD2 to SD8 mainly performed by the interlocking source alarm processing unit 71a) performed when the house alarm 10 detects an abnormality and the other house alarms 10 are abnormal. Is largely divided into interlocking destination alarm processing (SD9 to SD15 processing mainly performed by the interlocking destination alarm processing unit 71b).

  Here, when the smoke concentration in the room exceeds a predetermined level and a fire detection signal is output from the smoke detector 21 of the sensor unit 20, it is considered that the residential alarm 10 has detected an abnormality. Therefore (SD1, Yes), the interlocking source alarm processing unit 71a causes the transmitting unit 31 to transmit an alarm signal in order to output the interlocking destination alarm to the other home alarm devices 10 (SD2). At the same time, the interlocking source alarm processing unit 71a causes the speaker 41 to output an interlocking source alarm to notify the user in the room of the abnormality of the room (SD3). In addition, while the smoke detector 21 outputs the fire detection signal, the interlocking source alarm processing unit 71a causes the transmission unit 31 to repeatedly transmit the alarm signal every predetermined time. Further, while the smoke detector 21 of the sensor unit 20 outputs a fire detection signal, the controller 70 turns on or blinks the LED 42 provided in the alarm stop switch 51 (hereinafter referred to as an SD10 interlocking destination alarm described later). The control unit 70 may turn on the LED 42 or the like at the time of output.

  After the processing of SD3, it is considered that the abnormality that has occurred in the room due to fire extinguishing activities by the user or the interlocking source alarm is stopped by the user. The stop processing unit 73 performs processing for determining whether or not to stop the interlocking source alarm. For example, the restoration determination unit 72 determines whether or not it is necessary to restore the residential alarm device 10 to the normal monitoring state based on whether or not an abnormality has occurred in the room. Further, the alarm stop processing unit 73 determines whether or not to stop the interlock source alarm based on the presence or absence of an instruction to stop the alarm.

  Specifically, the restoration determination unit 72 determines whether or not it is necessary to restore the home alarm device 10 based on the presence or absence of a fire detection signal output from the smoke detector unit 21 of the sensor unit 20 (SD4). . Here, when the fire detection signal is no longer output from the smoke detector 21 of the sensor unit 20, it is considered that the residential alarm 10 has not detected an abnormality (SD 4, Yes), so the recovery determination unit 72. Determines that the dwelling device 10 should be restored. In response to this determination, the interlocking source alarm processing unit 71a transmits a recovery signal in order to stop the interlocking destination alarm with respect to the other residential alarm devices 10 (SD5). At the same time, the interlocking source alarm processing unit 71a stops the interlocking source alarm output from the speaker 41 (SD8), returns to immediately before SD1, and restores the home alarm device 10 to the normal monitoring state.

  Moreover, when the fire detection signal is output from the smoke detection unit 21 of the sensor unit 20, it is considered that the house alarm device 10 has detected an abnormality (SD 4, No), so the recovery determination unit 72 is It is determined that the residence guard 10 should not be restored. In response to this determination, the alarm stop processing unit 73 further determines whether or not to stop the interlocking source alarm based on the presence or absence of the alarm stop operation of the alarm stop switch 51 (SD6). Here, when the interlock source alarm is not stopped because the alarm stop operation of the alarm stop switch 51 has not been performed (No in SD6), the interlock source alarm processing unit 71a is connected to the interlock source alarm by the speaker 41. Is continuously output, and the process returns to immediately before SD1. On the other hand, when it is determined that the interlock source alarm is stopped due to the alarm stop operation of the alarm stop switch 51 (SD6, Yes), the interlock source alarm processing unit 71a is connected to another resident alarm device. In order to stop the interlocking destination alarm with respect to 10, a stop signal is transmitted (SD7). At the same time, the interlocking source alarm processing unit 71a stops the interlocking source alarm output from the speaker 41 (SD8) and returns to immediately before SD1.

  On the other hand, in SD1, when the smoke detection unit 21 of the sensor unit 20 outputs a fire detection signal because the smoke concentration in the room falls below a predetermined level, the residential alarm 10 detects an abnormality. Since it is thought that there is no (SD1, No), the control unit 70 is transmitted from the other resident alarm 10 by the receiving unit 32 in order to determine whether or not the other resident alarm 10 has detected an abnormality. It is monitored whether an alarm signal is received (SD9).

  Here, when an alarm signal is received by the receiving unit 32 from the other house alarm device 10 (SD9, Yes), it is considered that the other house alarm device 10 has detected an abnormality. The processing unit 71b causes the speaker 41 to output an interlocking destination alarm in order to notify the user in the room that an abnormality has occurred in another room (SD10). On the other hand, when the alarm signal is not received from the other residential alarm device 10 by the receiving unit 32 (No in SD9), it is considered that the other residential alarm device 10 has not detected an abnormality. The processing unit 71b proceeds to SD11 without outputting the interlocking destination alarm.

  After the processing of SD10, the abnormality that has occurred in the other room due to the fire extinguishing activity by the user disappears, or the interlocking destination alarm or the interlocking source alarm output from the other mortgage alarm 10 by the user is stopped. Therefore, the recovery determination unit 72 or the alarm stop processing unit 73 performs a process of determining whether or not to stop the interlocking destination alarm. For example, the recovery determination unit 72 determines whether or not the other home alarm device 10 has recovered based on whether or not a recovery signal transmitted from the other home alarm device 10 has been received. Further, the alarm stop processing unit 73 determines whether or not to stop the interlocking destination alarm output from the other home alarm device 10 based on whether or not the stop signal transmitted from the other home alarm device 10 is received. Determine.

  Specifically, the recovery determination unit 72 determines whether or not the reception unit 32 has received a recovery signal from all of the other residential alarm devices 10 that are transmitting the alarm signal (SD11). Here, when the receiving part 32 has received the recovery signal from all of the other home alarm devices 10 that are transmitting the alarm signal (SD11, Yes), there is an abnormality in any of the other home alarm devices 10. Therefore, the interlocking destination alarm processing unit 71b stops the interlocking destination alarm output from the speaker 41 (SD15). In addition, although the specific method of determining whether the recovery signal is received from all the other residence police devices 10 which are transmitting the warning signal is arbitrary, for example, the recovery determination part 72 is the receiving part 32. The transmission source code 81a included in the alarm signal received by the transmission signal 81 and the transmission source code 81a included in the received recovery signal are stored in the state storage area 81b of the storage unit 80 and collated as necessary. When all the original codes 81a match, it may be determined that a recovery signal has been received from all of the other home alarm devices 10 that have transmitted the alarm signal (hereinafter, in the processing of SD12 described later, In the same manner as this, it is determined whether or not the alarm stop processing unit 73 has received a stop signal from all the other residential alarm devices 10 that are transmitting the alarm signal).

  Moreover, when the receiving part 32 has not received the recovery signal from all the other residential alarm devices 10 that are transmitting the alarm signal (SD11, No), at least a part of the other residential alarm devices 10 is still Since it is considered that an abnormality has been detected, the interlocking destination alarm processing unit 71 b continues to output the interlocking destination alarm by the speaker 41. Thereafter, the alarm stop processing unit 73 determines whether or not the reception unit 32 has received a stop signal from all of the other residential alarm devices 10 that are transmitting the alarm signal (SD12). Here, when the receiving unit 32 has received stop signals from all of the other home alarm devices 10 that are transmitting alarm signals (SD12, Yes), the other home alarm devices 10 have detected an abnormality. Regardless of whether the alarm is present or not, since it is considered that the user's instruction is to stop the alarm, the interlocking destination alarm processing unit 71b stops the interlocking destination alarm output from the speaker 41 (SD15).

  Moreover, when the receiving part 32 has not received the stop signal from all the other residential alarm devices 10 that are transmitting the alarm signal (SD12, No), at least a part of the other residential alarm devices 10 still remains. Since the abnormality is detected and it is considered that it is not a user's instruction to stop the alarm, the interlocking destination alarm processing unit 71b continues to output the interlocking destination alarm by the speaker 41. Thereafter, the alarm stop processing unit 73 determines whether or not to stop the interlocking destination alarm based on the presence or absence of the alarm stop operation of the alarm stop switch 51 of the residential alarm 10 (SD13). Here, when it is determined that the alarm stop operation of the alarm stop switch 51 has not been performed (No in SD13), the interlocking destination alarm processing unit 71b continuously outputs the interlocking destination alarm by the speaker 41, and the SD1 Return to just before. On the other hand, when it is determined that the alarm stop operation of the alarm stop switch 51 has been performed (SD13, Yes), the interlocking destination alarm processing unit 71b stops the interlocking destination alarm output from the other residential alarm device 10. Therefore, a stop signal is transmitted (SD14), the interlocking destination alarm output from the speaker 41 is stopped (SD15), and the process returns to SD1.

(Regarding the interlocking source alarm processing of the home alarm 10A)
Next, as the interlocking source alarm process of the home alarm device 10A, the processes of SA1 to SA7 shown in FIG. 4 and the processes of SD1 to SD6 and SD8 shown in FIG.

  First, when it is detected that an abnormality has occurred in the bedroom where the residential alarm 10A is installed (SA1) (SD1, Yes), the interlocking source alarm processing unit 71a causes the transmission unit 31 to transmit an alarm signal ( SA2, SD2), the interlocking source alarm is output by the speaker 41 (SA3, SD3). Here, even when an alarm signal is received from the residential alarm 10C (SA4), the interlocking source alarm processing unit 71a of the residential alarm 10A continues to output only the interlocking source alarm through the speaker 41 (SA5).

  Here, until the process of SA6 is reached, the control unit 70 repeats the processes of SD1 to SD4 and SD6. For example, after the process of SA5, the recovery determination unit 72 determines whether or not an abnormality has been detected (SD4), and if there is an abnormality detection (SD4, No), the alarm stop processing unit 73 performs an alarm stop operation of the alarm stop switch 51. Whether or not to stop the interlock source alarm is determined based on the presence or absence of the alarm (SD6), but if the alarm stop operation of the alarm stop switch 51 is not performed, it is determined that the interlock source alarm is not stopped (SD6, No), return to SD1.

  Thereafter, the restoration determination unit 72 determines whether or not an abnormality has been detected (SD4). If there is no abnormality detection (SA6) (SD4, Yes), the linkage source alarm processing unit 71a The recovery signal is transmitted (SA7, SD5), the interlocking source alarm is stopped (SD8), and the process returns to SD1.

(Regarding the interlocking destination alarm processing of the home alarm 10B)
Next, as the interlocking destination alarm process of the home alarm device 10B, the processes of SB1 to SB10 shown in FIG. 4 and the processes of SD1, SD9 to SD13, and SD15 shown in FIG.

  First, when it is detected that no abnormality has occurred in the living room where the home alarm device 10B is installed (SD1, No), the control unit 70 has received an alarm signal from the home alarm devices 10A and 10C. Whether or not is monitored (SD9). Here, when an alarm signal is received from the housing alarm device 10A (SB1) (SD9, Yes), the interlocking destination alarm processing unit 71b causes the speaker 41 to output an interlocking destination alarm (SB2, SD10). Further, when an alarm signal is subsequently received from the residential alarm device 10C (SB3) (SD9, Yes), the interlocking destination alarm processing unit 71b continuously outputs the interlocking destination alarm (SB4, SD10).

  After the process of SB4, until the process of SB9 is reached, the control unit 70 repeats the processes of SD1, SD9 to SD13. For example, after the processing of SB4 and SD10, the recovery determination unit 72 receives the recovery signal from only the mortgage 10C to which the reception unit 32 is transmitting the alarm signal (SB5), the reception unit 32 receives the alarm signal. If it is determined that the restoration signal has not been received from all of the housing alarm devices 10A and 10C that are transmitting (SD11, No), and the stop signal is received only from the housing alarm device 10A (SB7), the receiving unit 32 determines that the stop signal has not been received from all of the residential alarm devices 10C that are transmitting alarm signals (SD12, No), and further performs an alarm stop operation of the alarm stop switch 51 in the residential alarm device 10B. If not (SD13, No), the linkage destination alarm is continuously output (SB6, SB8, SD10).

  On the other hand, in the process of SB9, the recovery determination unit 72 determines that the reception unit 32 has received the recovery signal from the residential alarm device 10C that is transmitting the alarm signal (SB9) (SD11, Yes). The interlocking destination alarm processing unit 71b stops the interlocking destination alarm output from the speaker 41 (SB10, SD15).
