(processing)
Next, management processing executed by the sensor 100 and the management device 40 of FIG. 1 configured as described above will be described. FIG. 3 is a flowchart of the management process (in the following description of each process, step is abbreviated as “S”). The “management process” is a process for managing the plurality of sensors 100, and specifically, a process for performing at least timing adjustment control. The timing for executing this management process is arbitrary. For example, after the sensor 100 and the management apparatus 40 are turned on, the management process is repeatedly started and executed every predetermined period (for example, 10 days). A description will be given from the start of the management process. In the following description, each part or element of the generically named sensor 100 in FIG. 1 is simply referred to as “communication part of the sensor 100” or the like without showing a reference numeral.

  First, as shown in FIG. 3, in SA1, the adjustment control unit 451 of the management device 40 transmits a request signal that is a signal for requesting battery voltage information. Here, for example, management target information (for example, “ID1” to “ID3” that are sensor IDs to be managed is included) that specifies the sensor 100 that is the management target of the management device 40 of FIG. (Information) is recorded in the recording unit 44 of the management device 40, which will be described below. Specifically, for SA1, the management target information is acquired from the recording unit 44, a request signal including the sensor ID of the acquired management target information is generated, and the generated request signal is transmitted to the communication unit 41 and the communication network N1. Is transmitted to the sensor 100. Here, for example, a request signal including “ID1” to “ID3” is generated and transmitted.

  Returning to FIG. 3, on the other hand, in SB <b> 1, the control unit of the sensor 100 determines whether or not a request signal to itself is received. Specifically, the communication unit of the sensor 100 of FIG. 1 is monitored, and the sensor ID included in the request signal received by the communication unit of the sensor 100 is acquired. It compares with sensor ID of a recording part, and it determines based on whether these correspond. When the communication unit of the sensor 100 has not received the request signal, or when the acquired sensor ID does not match the sensor ID of the recording unit of the sensor 100, the request signal to itself is received. SB1 is repeatedly executed until it is determined that the request signal has been received (NO in SB1). If the acquired sensor ID matches the sensor ID of its own recording unit, it is determined that a request signal to itself has been received (YES in SB1), and the process proceeds to SB2. Here, for example, since the request signals including “ID1” to “ID3” are transmitted, each control unit of the sensor 100 determines that the request signal to itself has been received.

  Returning to FIG. 3, in SB3, the control unit of the sensor 100 acquires its own battery voltage information. A specific method for acquiring battery voltage information is arbitrary, but here, for example, each of the sensors 100 in FIG. 1 includes a known voltage measuring unit that measures the output voltage of the battery of its own power supply unit. This will be described below as acquisition using this voltage measuring means. Specifically, for the processing of SB2, the value of the output voltage measured by the voltage measuring means is acquired as battery voltage information. Here, for example, the measurement value of the voltage measurement unit of the sensor 10 is “2.89”, the measurement value of the voltage measurement unit of the sensor 20 is “2.91”, and the voltage measurement unit of the sensor 30 is, for example. Is “2.91”, the sensor 10 acquires “2.89” as the battery voltage information, the sensor 20 acquires “2.91” as the battery voltage information, and the sensor 30. Acquires “2.91” as battery voltage information.

  Returning to FIG. 3, in SB <b> 2, the control unit of the sensor 100 transmits a response signal that is a response to the request signal. Specifically, the control unit of the sensor 100 of FIG. 1 acquires the sensor ID from its own recording unit, and generates a response signal including the acquired sensor ID and the battery voltage information acquired by the SB2. The generated response signal is transmitted to the management device 40 via the communication unit of the sensor 100 and the communication network N1. Here, for example, the sensor 10 generates and transmits a response signal including “ID1” and “2.89”, and the sensor 20 generates a response signal including “ID2” and “2.91”. Then, the sensor 30 generates and transmits a response signal including “ID3” and “2.91”.

  Returning to FIG. 3, on the other hand, in SA2, the adjustment control unit 451 of the management device 40 receives the response signal. Specifically, the response signal transmitted in SB3 is received via the communication unit 41 in FIG. Here, for example, a response signal including “ID1” and “2.89”, a response signal including “ID2” and “2.91”, and a response signal including “ID3” and “2.91” are received. .

  Returning to FIG. 3, in SA3, the adjustment control unit 451 of the management device 40 updates the battery voltage history information of the recording unit 44. Specifically, the battery voltage history information is updated based on the response signal received at SA2. Here, for example, the following description will be given on the assumption that the management device 40 of FIG. 1 includes a timing unit (not shown) that counts the date and time. In detail about the process of SA3, the date and time when the process of SA2 was performed is specified based on the time measurement result of the time measuring means of the management device 40, and the sensor ID and battery included in the response signal received at SA2 After acquiring the voltage information, the specified date and time, the acquired sensor ID and the battery voltage information are associated with each other and accumulated and updated in the battery voltage history information of the recording unit 44. Here, for example, when each response signal is received at SA2 at “13:00 on March 01, 2015”, the information shown in FIG. Accumulate and update information up to.

  Returning to FIG. 3, in SA4, the adjustment control unit 451 of the management device 40 determines whether or not to perform timing adjustment control and sensitivity adjustment control. Specifically, the determination is made based on information received at SA2 and accumulated at SA3. Here, the “time adjustment control” is the control described above, and specifically, the control for adjusting the light emission period of the light emitting unit of the physical quantity detecting unit of the sensor 100 of FIG. “Sensitivity adjustment control” is control for adjusting the sensitivity of detecting an abnormality in at least one of the plurality of sensors 100. Specifically, the “sensitivity adjustment control” is a control of the recording unit of the sensor 100. This control adjusts the fire determination threshold. In detail regarding SA4, whether or not to perform timing adjustment control and sensitivity adjustment control may be determined individually or collectively, but here, a case where determination is collectively performed will be described. . The specific determination method is arbitrary as long as the information received at SA2 and stored at SA3 is used. Here, for example, an arbitrary method is used based on the battery voltage information of FIG. A case will be described in which the future output voltage of the battery is predicted and a determination is made based on the predicted output voltage.

  FIG. 4 is a graph showing an example of a change in the output voltage of the battery. The horizontal axis in FIG. 4 indicates the elapsed time, and the vertical axis indicates the output voltage. The plot of FIG. 4 shows the past output voltage value, and the broken line shows the predicted output voltage value. Specifically, the details of the process of SA4 are as follows. First, in the battery voltage history information of the recording unit 44, battery voltage information corresponding to each of the sensors 100 is acquired, and a known method is based on the change of the acquired battery voltage information. An approximate curve is obtained at, and a predicted value of the output voltage is calculated based on the obtained approximate curve to generate a plot and a broken line in FIG. Next, based on the predicted value of the output voltage of the battery of each sensor 100 and the determination threshold voltage of the recording unit 44, the expected replacement is a time when the output voltage of the battery of each sensor 100 matches the determination threshold voltage. Get the time. Specifically, the expected replacement times T1 to T3, which are times corresponding to the intersections between the broken line in FIG. 4 and the two-dot chain line indicating the determination threshold voltage, are acquired. The expected replacement time T1 is the predicted replacement time of the sensor 10, the expected replacement time T2 is the predicted replacement time of the sensor 20, and the expected replacement time T3 is the predicted replacement time of the sensor 30. Next, among the acquired predicted replacement times (hereinafter referred to as acquired predicted replacement times) (in the case of FIG. 4, the predicted replacement times T1 to T3), the farthest predicted replacement time (hereinafter referred to as the predicted final replacement time) (see FIG. 4, based on the predicted replacement time T3), whether or not the predicted replacement time in which the time difference with respect to the predicted final replacement time is equal to or greater than the determination threshold period of the recording unit 44 is included in the acquired predicted replacement time. Based on this, it is determined whether or not the timing adjustment control and the sensitivity adjustment control are performed in SA4 of FIG. Then, when the predicted replacement time in which the time difference with respect to the predicted final replacement time is equal to or greater than the determination threshold period of the recording unit 44 is not included in the acquired predicted replacement time, it is determined that the timing adjustment control and the sensitivity adjustment control are not performed. (SA4 NO), the process proceeds to SA8. In addition, when the predicted replacement time in which the time difference with respect to the predicted final replacement time is equal to or longer than the determination threshold period of the recording unit 44 is included in the acquired predicted replacement time, it is determined that the timing adjustment control and the sensitivity adjustment control are performed. (YES in SA4), the process proceeds to SA5.

  In addition, when the number of repeated executions of the management process of FIG. 3 is small and the number of pieces of battery voltage information corresponding to each sensor 100 is small in the battery voltage history information of the recording unit 44 of FIG. 3), in SA4 of FIG. 3, it is determined that the timing adjustment control and the sensitivity adjustment control are not performed after outputting the information notifying that the battery voltage information is small via the display unit 43 of FIG. However (NO in SA4), the process may move to SA8.

  Here, for example, as shown in FIG. 4, the predicted replacement time T3 of the sensor 30 is farthest from the present, and the deviation of the predicted replacement time T2 of the sensor 20 with respect to the predicted replacement time T3 is “one week”. When the deviation of the predicted replacement time T1 of the sensor 10 from the predicted replacement time T3 is “3 months”, it is determined in SA4 in FIG. 3 that the time adjustment control and the sensitivity adjustment control are performed.

  Next, in SA5, the adjustment control unit 451 of the management device 40 determines the control content of the timing adjustment control. Specifically, the timing adjustment control object and the timing adjustment control adjustment amount are determined based on the determination result of SA4. Here, the “timing adjustment control target” is a control target of the timing adjustment control. The “time adjustment control adjustment amount” is an adjustment amount of a control item of the time adjustment control, and specifically, an increase / decrease amount of the light emission period of the light emitting unit of the sensor 100.

  First, details of the determination of the timing adjustment control target are arbitrary. For example, the timing adjustment control is performed on a sensor in which the time difference with respect to the expected final replacement time in SA4 is equal to or greater than the determination threshold period of the recording unit 44. Decide as a target. Here, for example, the sensor 10 is determined as a timing adjustment control target.

  The timing adjustment control adjustment amount can be determined in any detail. For example, the light emission period of the light emitting part of the sensor 100 is extended (for example, the light emitting part is maintained in a state where the light emission time of the light emitting part is kept constant). In consideration of the fact that the power consumption of the sensor 100 decreases as the time of the light-off time increases, the light-off time to be added is determined as the timing adjustment control adjustment amount. The length of the “lighting-out time to be added” here can be arbitrarily determined, but here, for example, a table for identifying a change in the amount of power consumption with respect to a change in the light-off time in the light emitting unit, or An arithmetic expression is prepared and is determined using this table or arithmetic expression. Here, for example, the “light-out time to be added” of “30 (seconds)” is determined as the timing adjustment control adjustment amount.

  Next, in SA6, the adjustment control unit 451 of the management device 40 determines the control content of the sensitivity adjustment control. Specifically, the sensitivity adjustment control target and the sensitivity adjustment control adjustment amount are determined based on the determination result of SA4. Here, the “sensitivity adjustment control target” is a control target of the sensitivity adjustment control. The “sensitivity adjustment control adjustment amount” is an adjustment amount of a control item of sensitivity adjustment control, and specifically, an increase / decrease amount of the fire determination threshold value of the recording unit of the sensor 100.

  First, the details of the determination of the sensitivity adjustment control target are arbitrary. For example, the sensitivity adjustment is performed on the sensor 100 in which the time difference with respect to the predicted final replacement time in SA4 is less than the determination threshold period of the recording unit 44. Determine as a control target. Here, for example, the sensors 20 and 30 of FIG. 1 are determined as timing adjustment control targets.

  The determination of the sensitivity adjustment control adjustment amount is arbitrary in detail. For example, as the value of the fire determination threshold value of the recording unit of the sensor 100 decreases, the sensor 100 becomes easier to detect fire (that is, In consideration of the increase in sensitivity), the amount of decrease that is the amount by which the fire determination threshold is decreased is determined as the sensitivity adjustment control adjustment amount. The value of the “decrease amount of the fire determination threshold value” here can be arbitrarily determined, but here, for example, the predetermined “decrease amount of the fire determination threshold value” of “1 (%)” is set. The sensitivity adjustment control adjustment amount is determined.

  Returning to FIG. 3, in SA7, the adjustment control unit 451 of the management device 40 transmits a control signal. Here, the “control signal” is a signal for controlling the sensor 100, for example, a timing adjustment control signal for performing timing adjustment control and a sensitivity adjustment control signal for performing sensitivity adjustment control. is there.

  First, with respect to the timing adjustment control signal, specifically, after generating the timing adjustment control signal including the sensor ID of the timing adjustment control target determined in SA5 and the timing adjustment control adjustment amount, the generated timing adjustment control signal is It transmits to the sensor 100 via the communication part 41 and the communication network N1 of FIG. Here, for example, a timing adjustment control signal including “ID1” and “30 (seconds)” is generated and transmitted.

  Further, for the sensitivity adjustment control signal, specifically, after generating the sensitivity adjustment control signal including the sensor ID and sensitivity adjustment control adjustment amount determined in SA6, the generated sensitivity adjustment control signal is The data is transmitted to the sensor 100 via the communication unit 41 and the communication network N1. Here, for example, a sensitivity adjustment control signal including “ID2”, “ID3”, and “1 (%)” is generated and transmitted.

  Returning to FIG. 3, on the other hand, in SB4, the control unit of the sensor 100 determines whether or not a control signal to itself has been received. Specifically, the communication unit of the sensor 100 of FIG. 1 is monitored, and the sensor ID included in the control signal received by the communication unit of the sensor 100 is acquired. It compares with sensor ID of a recording part, and it determines based on whether these correspond. When the communication unit of the sensor 100 does not receive a control signal, or when the acquired sensor ID does not match the sensor ID of its own recording unit, the control signal to itself is received. SB4 is repeatedly executed until it is determined that it has not been received (NO in SB4) and it is determined that a control signal to itself has been received. If the acquired sensor ID matches the sensor ID of its own recording unit, it is determined that a request signal to itself has been received (YES in SB4), and the process proceeds to SB5. Here, for example, the control unit 16 of the sensor 10 determines that the timing adjustment control signal has been received, and the control unit 26 of the sensor 20 and the control unit 36 of the sensor 30 have received the sensitivity adjustment control signal. Judge that it is.

  Returning to FIG. 3, in SB5, the control unit of the sensor 100 performs control. Specifically, information included in the control signal received in SB4 is acquired, and timing adjustment control or sensitivity adjustment control is performed based on the acquired information.

  Here, for example, the control unit 16 of the sensor 10 of FIG. 1 acquires “30 (seconds)” as information included in the control signal received in SB4, and the light emission time of the light emission unit of the physical quantity detection unit 12 In such a state, control for extending the turn-off time by 30 (seconds) is performed, and light emission and turn-off of the light emitting unit of the physical quantity detection unit 12 are repeatedly performed in the state after the control. Since the light emission cycle of the sensor 10 is extended after this control, the power consumption is reduced as compared with that before the control. Therefore, the expected replacement time T1 in FIG. 4 can be shifted to the expected replacement time T3 side.

  Further, for example, the control unit 26 of the sensor 20 acquires “1 (%)” as information included in the control signal received in SB4, and decreases the fire determination threshold of the recording unit 25 by 1 (%). Control is performed, and fire detection processing by the control unit 26 is performed in a state after the control. Here, the “fire detection process” is a known process for detecting a fire. For example, when the detection result of the physical quantity detection unit 22 is equal to or greater than the fire determination threshold value of the recording unit 25, a fire is detected. When the detection result of the physical quantity detection unit 22 is less than the fire determination threshold value of the recording unit 25, it is a process that does not detect a fire.

  Further, for example, the control unit 36 of the sensor 30 acquires “1 (%)” as information included in the control signal received by the SB 4 in the same manner as the control unit 26 of the sensor 20. Control to reduce the fire determination threshold of the recording unit 35 by 1 (%) is performed, and fire detection processing by the control unit 36 is performed in a state after the control. The sensors 20 and 30 after these controls increase the sensitivity of detecting a fire, and thus, for example, assist the operation of the sensor 10 in which the light emission period may be extended and the fire detection speed may be slightly delayed. The fire can be reliably detected in the entire monitoring area of the sensor 100.

  Returning to FIG. 3, on the other hand, in SA8 after SA7, the adjustment control unit 451 of the management device 40 determines whether or not to perform replacement guidance regarding at least one of the sensors 100. The determination method here is arbitrary, but here, for example, the remaining lifetime that is a period between the expected replacement time used in SB4 and the current date and time (specifically, the date and time when SA8 is executed) A case will be described in which the period is calculated, the calculated remaining life period and a predetermined guidance determination period (for example, one month) are compared for each of the sensors 100 in FIG. If the calculated remaining lifetime is equal to or longer than the predetermined guidance determination period for all the sensors 100, it is determined that no guidance is provided (NO in SA8), and the process is terminated. If the calculated remaining lifetime is less than the predetermined guidance determination period for at least one sensor in the sensor 100, it is determined that guidance is to be performed (YES in SA8), and the process proceeds to SA9.

  Next, in SA9, the adjustment control unit 451 of the management device 40 provides replacement guidance regarding at least one of the sensors 100. Here, for example, “The sensor replacement time is approaching. Replace the sensor.” Or “The sensor battery replacement time is approaching. Replace the sensor battery.” Are displayed on the display unit 43 of the management device 40 of FIG. This completes the management process.

In addition, for example, it is possible to prevent the sensor 100 that has been left for a long period of time (for example, one year) before meeting a predetermined replacement standard from being replaced in vain.

  In addition, by performing the control for adjusting the period of the disaster prevention operation as the timing adjustment control, for example, it is not necessary to completely stop the operation of the plurality of sensors 100, so that the reliability of the plurality of sensors 100 for disaster prevention is improved. Can be maintained.

  Further, by adjusting the sensitivity for detecting the abnormality in the sensor 100 based on the battery voltage information, for example, the degree of influence by the timing adjustment control for detecting the abnormality in the monitoring region can be reduced. The reliability of the plurality of detectors 100 for disaster prevention can be maintained.

  In addition, by performing replacement guidance regarding the sensor 100, for example, the user can be notified of the replacement timing of the sensor 100, so that the sensor 100 can be managed appropriately.

[Modifications to Embodiment]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can do. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above contents, and may vary depending on the implementation environment and the details of the configuration of the invention. May be solved, or only some of the effects described above may be achieved.

(About distribution and integration)
The above-described configuration is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific forms of distribution and integration of the respective units are not limited to those shown in the drawings, and all or a part thereof can be configured to be functionally or physically distributed or integrated in arbitrary units. The “system” in the present application is not limited to one configured by a plurality of devices, but includes one configured by a single device. In addition, the “apparatus” in the present application is not limited to one configured by a single apparatus, but includes one configured by a plurality of apparatuses. For example, each unit for executing the management process of FIG. 3 among the units of the management device 40 may be provided in at least some of the sensors 100.

(About battery voltage information)
Moreover, although the said embodiment demonstrated the case where the management apparatus 40 requests | requires battery voltage information in SA1 of FIG. 3, it is not restricted to this. For example, the sensor 100 voluntarily transmits its own battery voltage information to the management device 40 at a predetermined transmission timing without requesting the management device 40, and the management device 40 receives the battery voltage information. You may comprise so that a management process may be performed. Here, the “predetermined transmission timing” is a timing at which the sensor 100 transmits the battery voltage information and is an arbitrary timing. For example, a predetermined period (for example, 10 The timing may be every other day, or may be every predetermined period (for example, 10 days) after the output voltage of the battery of the sensor 100 falls below the transmission start voltage. The “transmission start voltage” is a reference voltage value for starting transmission of battery voltage information, and is, for example, a voltage value higher than the “determination threshold voltage” in the embodiment.

(About judgment (1))
Moreover, although the said embodiment demonstrated the case where timing adjustment control and sensitivity adjustment control were collectively determined by the same reference | standard in SA4 of FIG. 3, it is not restricted to this. For example, whether or not timing adjustment control is performed and whether or not sensitivity adjustment control is performed may be individually determined based on different criteria. Specifically, as the “determination threshold period” described in the embodiment, “determination threshold period for timing adjustment control” for determination of timing adjustment control, and “determination threshold for sensitivity adjustment control” for determination of sensitivity adjustment control. By adopting “period” and setting the determination threshold period for timing adjustment control to be longer than the determination threshold period for sensitivity adjustment control, the following determination may be made. Specifically, it is determined whether or not the timing adjustment control is performed using the timing adjustment control determination threshold period, and whether or not the sensitivity adjustment control is performed using the sensitivity adjustment control determination threshold period. judge. The above-described determination may be performed after setting the determination threshold period for timing adjustment control to be shorter than the determination threshold period for sensitivity adjustment control.

(About judgment (2))
Moreover, although the said embodiment demonstrated the case where it determined based on "expected replacement | exchange time" demonstrated using FIG. 4 in SA4 and SA8 of FIG. 3, it is not restricted to this. For example, the determination may be made using the current output voltage. Specifically, “timing adjustment control threshold voltage” for determination of timing adjustment control, “threshold voltage for sensitivity adjustment control” for determination of sensitivity adjustment control, and “threshold voltage for guidance determination” for determination of guidance The data is recorded in the recording unit 44 of the management device 40, and the current output voltage of the battery of the power supply unit of each sensor 100 is grasped in the same manner as the processing of SA1 and SA2 in FIG. 3 of the embodiment. In the above, it may be determined as follows. More specifically, it is determined that the timing adjustment control is performed only when a sensor having an output voltage lower than the threshold voltage for timing adjustment control is present in the sensor 100, and more than the threshold voltage for sensitivity adjustment control. Only when a sensor with a low output voltage exists in the sensor 100, it is determined that the sensitivity adjustment control is performed, and a sensor with an output voltage lower than the threshold voltage for guidance determination exists in the sensor 100. It may be determined that the guidance is performed only when it is performed. Note that the values and magnitude relationships of these threshold voltages are arbitrary as long as they are within the “normal voltage range” described in the embodiment, and at least two of them may be the same, Although the three may be different from each other, for example, the threshold voltage for timing adjustment control becomes larger than the threshold voltage for sensitivity adjustment control, and the threshold voltage for sensitivity adjustment control becomes larger than the threshold voltage for guidance determination, In addition, the guidance determination threshold voltage may be set to be larger than the “determination threshold voltage” in the embodiment.

(About the control contents of the timing adjustment control (1))
Further, in the above embodiment, in SA5 of FIG. 3, a sensor whose time difference with respect to the expected final replacement time in SA4 is equal to or longer than the determination threshold period of the recording unit 44 is determined as a timing adjustment control target. However, the present invention is not limited to this. For example, a part or all of the sensor 100 may be determined as a timing adjustment control target. When configured in this manner, after determining the “light-out time to be added” or “light-out time to be subtracted” described in the embodiment so that all expected replacement times of the sensor 100 are within the determination threshold period, The light emission period may be extended or shortened.

(About the control contents of the timing adjustment control (part 2))
Moreover, although the said embodiment demonstrated the case where only the light extinction time of the light emission part of the sensor 100 was adjusted as timing adjustment control, it is not restricted to this. Arbitrary control may be performed as long as the amount of power consumption of the light emitting unit of the sensor 100 can be changed. For example, only the light emitting time of the light emitting unit may be adjusted, or both the turn-off time and the light emitting time are adjusted. Alternatively, the amount of current supplied to the light emitting unit of the sensor 100 may be adjusted.

(Details of sensitivity adjustment control (Part 1))
Further, in the above embodiment, in SA6 in FIG. 3, a sensor whose timing difference with respect to the expected final replacement time in SA4 is less than the determination threshold period of the recording unit 44 is determined as a sensitivity adjustment control target. However, the present invention is not limited to this. For example, a part or all of the sensor 100 (including the sensor determined as the timing adjustment control target in SA5) may be determined as the sensitivity adjustment control target. Further, for example, only a sensor installed in the vicinity of the sensor determined as the timing adjustment control object in SA5 may be determined as the sensitivity adjustment control object.

(Details of sensitivity adjustment control (Part 2))
Moreover, although the said embodiment demonstrated the case where sensitivity was raised by determining the reduction amount of a fire determination threshold value as sensitivity adjustment control adjustment amount in SA6 of FIG. 3, it is not restricted to this. For example, after determining the sensitivity adjustment control target using the method “(Contents of sensitivity adjustment control (part 1))” of the embodiment or the modification, the frequency of occurrence of non-fire reports in the sensor 100 is determined. From the viewpoint of reducing and preserving the battery power of the sensor 100, the sensitivity may be lowered by determining the increase amount that is the amount by which the fire determination threshold is increased as the sensitivity adjustment control adjustment amount.

(About guidance)
Moreover, although the said embodiment demonstrated the case where the message etc. were displayed and guided on the display part 43 of the management apparatus 40 of FIG. 1 in SA9 of FIG. 3, it is not restricted to this. For example, the management device 40 may be provided with a known speaker or printer, and a message or the like may be output as audio from the speaker or printed out from the printer for guidance.

(About sensitivity adjustment control)
In addition, regarding the sensitivity adjustment control of SB5 of FIG. 3 in the above embodiment, a lower limit value may be set so that the fire determination threshold value is not too low, and the sensitivity adjustment control may be performed with the set lower limit value as a limit.

(About each process)
Moreover, in the management process of FIG. 3 of the said embodiment, you may abbreviate | omit or add arbitrarily about processes other than the process relevant to time adjustment control.

(About disaster prevention past information)
Further, disaster prevention past information is stored in the recording unit 44 of the management device 40 in FIG. 1, and the adjustment control unit 451 changes the change control time in addition to the timing adjustment control target and the timing adjustment control adjustment amount in SA5 in FIG. After the band is determined, the determined change control time period may be transmitted to the sensor 100 at SA7, and the timing adjustment control may be performed during the transmitted change control time period. Here, “disaster prevention past information” is past information related to disaster prevention, specifically, information on occurrence of abnormality in the monitoring area, for example, the sensor 100 for each time slot of the day. This information identifies the fire occurrence frequency in the same type of monitoring area. Further, the “change control time zone” is a time zone in which the control content is changed in the sensor 100, and specifically, is a time zone in which control based on the control signal transmitted in SA7 in FIG. 3 is to be performed.

  Specifically, when the characteristics of this modification are applied, the adjustment control unit 451 of the management device 40 determines the timing adjustment control target and the timing adjustment control adjustment amount in the same manner as in the embodiment, With reference to the disaster prevention past information in the recording unit 44, the time zone in which the fire occurrence frequency is lowest (for example, the time zone in units of 6 hours) is specified, and the specified time zone is determined as the change control time zone Then, in addition to the information described in the embodiment, a timing adjustment control signal including the determined change control time zone is transmitted to the sensor 100. And the sensor 100 which received this transmitted timing adjustment control signal light-emits with the light emission period based on the information contained in a timing adjustment control signal only in the change control time slot | zone included in a timing adjustment control signal. To control. Note that the recording unit 44 storing disaster prevention past information in this modification corresponds to “disaster prevention past information storage unit”. When comprised in this way, by performing time adjustment control based on disaster prevention past information and battery voltage information, for example, a pattern related to past disaster prevention (for example, the frequency of occurrence of fire for each time zone of the day, etc.) In consideration, the timing adjustment control can be performed in an appropriate time zone.

(About the output of presentation information)
Moreover, you may comprise so that the adjustment control part 451 of the management apparatus 40 of FIG. 1 of the said embodiment may output presentation information. Here, “presentation information” is information to be presented to the user, and is information based on the battery voltage information received by the communication unit 41.

  Specifically, when the characteristics of this modification are applied, the adjustment control unit 451 responds to a request from the user through the input unit 42 or performs predetermined processing (for example, SA3 in FIG. 3). ) Automatically generates and outputs presentation information. The presentation information to be generated is arbitrary. For example, the output voltage itself or statistical value (equivalent average value, median value, variance value, etc.) of each battery of the sensor 100, the history of the battery of each sensor 100, or It is a predicted value or the graph of FIG. Moreover, the output method of presentation information is arbitrary, for example, it may be displayed and output on the display unit 43 of FIG. 1, or as described in “(About Guidance)” of the modified example, audio output from the speaker Or printing out from a printer. In such a configuration, by outputting presentation information that is information based on battery voltage information and information to be presented to the user, for example, the state of the sensor 100 can be presented to the user. The device 100 can be appropriately managed.

(About status information)
Moreover, although the said embodiment demonstrated the case where battery voltage information was received as state information and timing adjustment control was performed, it is not restricted to this. For example, the timing adjustment control may be performed by receiving information specifying the state of deterioration of elements (for example, capacitors, LEDs, etc.) of disaster prevention equipment.
