As the second identification information stored in the storage unit 27, for example, the serial number or address number of the group monitor device 20 can be used.

(Processing-Communication processing)
Next, processing executed by the communication system 1 configured as described above will be described. First, the communication process which the group monitor apparatus 20 installed in each dwelling unit 3 performs is demonstrated. FIG. 4 is a flowchart of the communication process (in the following description of each process, step is abbreviated as “S”). This process is started after the power is turned on in each of the group monitor devices 20, for example. As a premise of this communication processing, when the wireless terminal 10 determines that an abnormality such as a fire has occurred based on the detection result by the sensor unit, information indicating that an abnormality such as a fire has occurred in the dwelling unit 3 (anomaly) Information) and first identification information for uniquely identifying itself is transmitted.

  As shown in FIG. 4, when the communication process is activated in the group monitor device 20, the abnormality determination unit 26a determines whether or not the abnormality switch is turned on (SA1).

  As a result, when the abnormal switch is turned on (SA1, Yes), the abnormality determining unit 26a determines that an abnormality has occurred in the dwelling unit 3 where the group monitor device 20 is installed, and the transfer unit 26b is in the dwelling unit 3. A signal (abnormal signal) including information indicating that an abnormality has occurred is transmitted from the communication unit 22 (SA2). The transfer unit 26b includes the second identification information stored in the storage unit 27 in the abnormal signal and causes the communication unit 22 to transmit the second identification information. It may be added to the abnormal signal that the abnormality determination is caused by pressing the abnormal switch.

  Subsequently, the transfer unit 26b waits until the restoration switch is turned on (SA3, No), and when the restoration switch is turned on (SA3, Yes), a signal (recovery signal) including information indicating that there is no abnormality in the dwelling unit 3 ) Is transmitted from the communication unit 22 (SA4). At this time, the transfer unit 26b includes the second identification information stored in the storage unit 27 in the recovery signal and causes the communication unit 22 to transmit it.

  In SA1, when the abnormality determination unit 26a determines that the abnormality switch is not turned on (No in SA1), the abnormality determination unit 26a determines whether the reception unit 23 has received a radio signal (SA5). . A specific determination method is arbitrary. For example, when a radio wave having a certain intensity or more is detected in the reception circuit of the reception unit 23, when a message included in the radio signal can be interpreted, the radio signal is It is determined that it has been received.

  As a result, when the abnormality determination unit 26a determines that the reception unit 23 has received a wireless signal (SA5, Yes), the abnormality determination unit 26a determines whether or not the received identification signal is included in the received wireless signal. Is determined (SA6). For example, it is determined whether or not the first identification information is included as the transmission source identification code of the message included in the received wireless signal.

  As a result, when the first identification information is not included in the wireless signal (SA6, No), the abnormality determining unit 26a indicates that the wireless signal received by the receiving unit 23 is a wireless signal from the wireless terminal 10 belonging to the communication system 1. Return to SA1.

  On the other hand, when the first identification information is included in the radio signal (SA6, Yes), the abnormality determination unit 26a determines whether or not the first identification information is stored in the storage unit 27 of the group monitor device 20. (SA7).

  As a result, when the first identification information included in the radio signal received by the reception unit 23 is not stored in the storage unit 27 (SA7, No), the abnormality determination unit 26a receives the radio signal received by the reception unit 23. Is a wireless signal from the wireless terminal 10 installed in another dwelling unit 3, and it is not necessary to perform abnormality determination based on the wireless signal, and the process returns to SA1.

  In addition, when the radio signal received at this time is a radio signal from another dwelling unit 3, if the content of the signal includes abnormality information such as a fire, there is a high possibility that an abnormality has occurred in a neighboring dwelling unit. From this, it is also possible to store information on the occurrence of abnormalities in the neighborhood and to perform a warning warning or warning display in advance. Even if the abnormal dwelling unit cannot be identified from the contents included in the received wireless signal, a simple alarm such as only a fire display may be performed based on the contents included in the wireless signal. If it is a dwelling unit in the same group that warns when an abnormality occurs, detailed contents such as an unusual place from the group monitoring device 20 of the abnormal dwelling unit via the coaxial cable 7 are included after a predetermined time has passed since the fire expanded. In this case, a detailed abnormality alarm specifying the dwelling unit name and the abnormality content can be performed. In this way, by performing a first-stage alarm by receiving a radio signal, and by performing a second-stage alarm by receiving an abnormality alarm from the coaxial cable, a step-by-step alarm according to the abnormality content can be performed, Both wireless systems and cable systems can be used effectively. In addition, when the wireless terminal 10 of the self-dwelling unit reports, the wireless terminals 10 also transmit and receive abnormal signals, and a plurality of wireless terminals of the same dwelling unit give an abnormality alarm, but wireless signals from other dwelling units are transmitted. When received, the alarm method may be changed by issuing an alarm only with the group monitor device 20.

  On the other hand, when the first identification information included in the radio signal received by the reception unit 23 is stored in the storage unit 27 (SA7, Yes), the abnormality determination unit 26a is configured to transmit the radio signal received by the reception unit 23. It is determined whether the information included in the data code is abnormal information (SA8). The abnormality determination unit 26a determines, for example, whether or not the information included in the data code is abnormal information by decoding a communication control code of a radio signal.

  As a result, when the information included in the data code of the wireless signal received by the receiving unit 23 is not abnormal information (SA8, No), for example, the information included in the data code of the wireless signal is If the information is for notifying that the output voltage of the battery is less than the threshold, or information for notifying that some failure has occurred in the wireless terminal 10, the abnormality determination unit 26 a It is assumed that there is no need to transmit any information to the dwelling unit 3, and the process returns to SA1. At this time, only the group monitor device 20 in the dwelling unit gives an alarm and notification according to the type of information.

  On the other hand, when the information included in the data code of the radio signal received by the receiving unit 23 is abnormal information (SA8, Yes), the abnormality determining unit 26a transmits a wireless signal including the abnormal information at that time. It is determined whether there are two or more wireless terminals 10 (reporting terminals) (SA9). For example, in the abnormality determination unit 26a, the reception unit 23 receives a plurality of wireless signals, the first identification information included in each wireless signal is different, and the information included in the data code of each wireless signal is abnormal. In the case of information, it is determined that the number of reporting terminals is two or more.

  As a result, when the number of reporting terminals is two or more (SA9, Yes), the abnormality determination unit 26a determines that an abnormality has occurred in the dwelling unit 3 in which the group monitor device 20 is installed, and the transfer unit 26b. Causes an abnormal signal to be transmitted from the communication unit 22 (SA2). At the time of transfer, the type and location code of the reporting terminal may be transmitted at the same time, and an unusual location or type may be specified and displayed at another dwelling unit.

  On the other hand, when the number of reporting terminals is not two or more (SA9, No), that is, when the number of reporting terminals is one, the abnormality determination unit 26a is in the dwelling unit 3 where the group monitor device 20 is installed. The pre-alarm flag indicating that an abnormality may have occurred is set to ON, and the transfer unit 26b transmits a signal (pre-alarm) including information indicating that an abnormality may have occurred in the dwelling unit 3 from the communication unit 22. (SA10). The transfer unit 26b includes the second identification information stored in the storage unit 27 in the pre-alarm and causes the communication unit 22 to transmit it. The pre-alarm flag is stored in the RAM of the control unit 26, for example. Thereafter, the control unit 26 returns to SA1. It is also possible to set so that an abnormal alarm is sent only to one's own house without sending an abnormality to the other dwelling units during the pre-alarm. The number of reporting terminals may be one and multiple, and the method of voice alerting at the wireless terminal may be different.

  In SA5, when the abnormality determination unit 26a determines that the reception unit 23 has not received a wireless signal (No in SA5), the abnormality determination unit 26a determines whether the pre-alarm flag is ON (SA11). ).

  As a result, when the pre-alarm flag is ON (SA11, Yes), the abnormality determination unit 26a has not received the radio signal even if a predetermined time has elapsed since the pre-alarm flag was turned ON. Therefore, the pre-alarm flag is turned OFF assuming that no abnormality has occurred in the dwelling unit 3 where the group monitor device 20 is installed, and the transfer unit 26b is informed that the possibility that the abnormality has occurred in the dwelling unit 3 has been cancelled. A signal (cancellation signal) including the signal is transmitted from the communication unit 22 (SA12). The transfer unit 26b includes the second identification information stored in the storage unit 27 in the release signal and causes the communication unit 22 to transmit it. Thereafter, the control unit 26 returns to SA1.

  On the other hand, if the pre-alarm flag is not ON (OFF) (SA11, No), the abnormality determination unit 26a assumes that no abnormality has occurred in the dwelling unit 3 in which the group monitor device 20 is installed, and SA1 Return.

(Processing-Output processing)
Next, the output process which the group monitor apparatus 20 installed in each dwelling unit 3 performs is demonstrated. FIG. 5 is a flowchart of the output process. This process is started after the power is turned on in each of the group monitor devices 20, for example, and is executed in parallel with the communication process described above.

  As shown in FIG. 5, when the communication process is started in the group monitor device 20, the output control unit 26 c receives an abnormal signal from the group monitor device 20 installed in another dwelling unit 3 via the communication unit 22. Is determined (SB1).

  As a result, when an abnormal signal is received from the group monitor device 20 installed in another dwelling unit 3 via the communication unit 22 (SB1, Yes), the output control unit 26c outputs an alarm from the display unit 24 or the speaker 25. (SB2). For example, the output control unit 26c refers to the storage unit 27 based on the second identification signal included in the abnormal signal, and identifies the dwelling unit 3 in which the group monitor device 20 that is the transmission source of the abnormal signal is installed. Then, an alarm indicating that an abnormality has occurred in the dwelling unit 3 (for example, “A fire has occurred at Mr. XX's house!”) Is output from the display unit 24 or the speaker 25. An alarm may be given of the type of the terminal that issued the abnormality, the monitoring location, and the like.

  Subsequently, the output control unit 26c waits until a restoration signal is received from the group monitor device 20 of the dwelling unit 3 that is the transmission source of the abnormal signal received at SB1 via the communication unit 22 (SB3, No), and receives the restoration signal. When it does (SB3, Yes), the alarm output from the display unit 24 or the speaker 25 is stopped (SB4). In the determination of SB3, the output control unit 26c is a recovery signal transmitted from the group monitor device 20 of the dwelling unit 3 that is the transmission source of the abnormal signal received in SB1, based on the second identification signal included in the recovery signal, for example. Determine whether. After SB4, the control unit 26 returns to SB1.

  Moreover, in SB1, when the abnormal signal is not received via the communication part 22 from the group monitor apparatus 20 installed in the other dwelling unit 3 (SB1, No), the output control part 26c is installed in the other dwelling unit 3. It is determined whether or not a pre-alarm has been received from the group monitor device 20 via the communication unit 22 (SB5).

  As a result, when the pre-alarm is not received from the group monitor device 20 installed in the other dwelling unit 3 via the communication unit 22 (SB5, No), the output control unit 26c has an abnormality in the other dwelling unit 3. It is assumed that there is no information to be output and the process returns to SB1.

  On the other hand, when the pre-alarm is received from the group monitor device 20 installed in another dwelling unit 3 via the communication unit 22 (SB5, Yes), the output control unit 26c outputs the pre-alarm from the display unit 24 or the speaker 25. (SB6). For example, the output control unit 26 c identifies the dwelling unit 3 in which the group monitor device 20 that is the transmission source of the pre-alarm signal is installed based on the second identification signal included in the pre-alarm, and an abnormality is detected in the dwelling unit 3. An alarm indicating that it may have occurred (for example, “There is a possibility of fire at Mr. XX's house”) is output from the display unit 24 or the speaker 25.

  Subsequently, the output control unit 26c waits until a release signal is received via the communication unit 22 from the group monitor device 20 of the dwelling unit 3 that has transmitted the pre-alarm received in SB5 (SB7, No), and receives the release signal. If it is performed (SB7, Yes), the output of the pre-alarm from the display unit 24 and the speaker 25 is stopped (SB8). In the determination of SB7, the output control unit 26c is a cancellation signal transmitted from the group monitor device 20 of the dwelling unit 3 that is the transmission source of the pre-alarm received in SB5 based on, for example, the second identification signal included in the cancellation signal. Determine whether. After SB8, the control unit 26 returns to SB1.
