The number of operations of the connected device is counted each time an alarm signal from the fire alarm device 4 or the gas leak alarm device 6 is input to the port Pio in step S1. Therefore, the number of operations of the connected device may be paraphrased as the number of times of input of an alarm signal (notification signal).

  Next, the alarm generation data indicating the alarm content of the alarm signal determined in step S3 is modulated by the modulation / demodulation processing digital processing circuit DP together with its own identification information registered in the non-volatile memory NVM, and the communication high frequency circuit Wireless transmission is performed from the unit RF to the antenna AT through the communication channel registered in the nonvolatile memory NVM (step S7). Next, the number of times of wireless transmission of alarm generation data is counted (step S8-1), and the counted number of wireless transmissions is registered in the nonvolatile memory NVM as history data of the wireless slave unit (step S8-2), and then step S1. Return to

  On the other hand, when the alarm signal from the fire alarm device 4 or the gas leak alarm device 6 is not input to the port Pio (N in step S1), the interruption occurrence data from the wireless master device 2 described in detail later, In the communication channel in which alarm generation data from other wireless slave units 3 and 5 are registered in the non-volatile memory NVM, the content including its own identification information is received by the antenna AT or the communication high-frequency circuit unit RF and used for modulation / demodulation processing. It is confirmed whether or not the signal is demodulated and inputted by the digital processing circuit DP (step S9).

  When the interruption occurrence data from the wireless master device 2 or the alarm occurrence data from the other wireless slave devices 3 and 5 are not input (N in step S9), the process proceeds to step S13 to be described later. (Y in step S9), the number of times of wireless reception from the wireless master device 2 and the other wireless slave devices 3 and 5 is counted (step S10-1), and the counted number of wireless receptions is stored in the nonvolatile memory NVM. It is registered as history data (step S10-2), and then the fire alarm 4 and gas leak alarm 6 indicate that the gas supply has been shut off by the shutoff valve of the gas meter 1 indicated in the shutoff occurrence data. An alarm state has occurred in the fire alarm device 4 or the gas leak alarm device 6 connected to the other wireless slave devices 3 and 5 indicated in the interruption notification signal to be notified by output or the alarm generation data. A fire alarm signal or a gas leak alarm device 6 connected to the port Pio generates an alarm notification signal to be notified by voice output, and is output from the port Pio to the fire alarm device 4 or the gas leak alarm device 6 After (step S11), the process returns to step S1.

  Further, in step S13, the handy terminal 7 to be described in detail later is reached in step S13 which proceeds to step S9 when no interruption occurrence data from the wireless master unit 2 or alarm generation data from other wireless slave units 3 and 5 is input in step S9. The history request signal is received from the antenna AT or the communication high-frequency circuit unit RF and is demodulated by the modulation / demodulation processing digital processing circuit unit DP. If it is not input (in step S13) N) Return to step S1.

  On the other hand, if a history request signal from the handy terminal 7 is input (Y in step S13), the number of wireless reception of the history request signal from the handy terminal 7 is counted (step S14-1), and the counted number of wireless receptions Is registered in the nonvolatile memory NVM as history data of the wireless slave unit (step S14-2). Next, the alarm history data of the alarm device registered in the nonvolatile memory NVM and the wireless device such as the number of transmissions and the number of receptions The history data is read out, and a history data signal including these is generated and modulated by the modulation / demodulation processing digital processing circuit DP together with its own identification information registered in the non-volatile memory NVM, and the communication high-frequency circuit unit RF Through the antenna AT, wireless transmission is performed using the communication channel registered in the nonvolatile memory NVM (step S15). Next, the number of wireless transmissions of the history data signal is counted (step S17-1), and the counted number of wireless transmissions is registered in the nonvolatile memory NVM as history data of the wireless slave unit (step S17-2), and then step S1. Return to

  In the wireless slave devices 3 and 5 of the above-described embodiment, the number of times of wireless transmission and reception of alarm generation data, the number of times of wireless reception of history request signals, and the number of times of transmission of history data signals are the number of wireless communications in the claims. Equivalent to.

  As described above, according to the automatic linkage system of the present embodiment, other necessary items such as time are added to the alarm contents of the alarm signal from the fire alarm device 4 and the gas leak alarm device 6 connected to the wireless slave devices 3 and 5. In addition to the added alarm history data being registered in the non-volatile memory NVM, the number of operations of the connected device, the frequency of radio transmission and reception of alarm generation data, the frequency of radio reception of history request signals, and the history data signal Since the wireless communication history data of the wireless device such as the number of wireless transmissions is also registered in the non-volatile memory NVM, the operation state detection history of the fire alarm device 4 and the gas leak alarm device 6 and the related wireless communication frequency of the wireless device itself The history data including can be stored and managed, and the cause investigation when the wireless device becomes abnormal can be facilitated. For example, an abnormal state related to battery consumption can be analyzed based on the total number of times of wireless transmission and wireless reception of the wireless device itself. Also, by analyzing the frequency of wireless transmission of alarm occurrence data, analyze whether the installation environment of the alarm device is an environment that is likely to generate an alarm state, or indirectly recognize alarm side alarms and It is possible to analyze whether or not the threshold value is appropriate, and to determine deterioration of the sensor.
