A heat sensor, a smoke sensor, or a flame sensor can be used for the first sensor 4a and the second sensor 4b. For example, the first sensing unit 4a is a differential spot type sensor, and the second sensing unit 4b is a constant temperature spot type sensor.

FIG. 3 is a block diagram showing the control system of the battery-type automatic fire extinguishing apparatus with function realizing means. The battery unit 30 supplies power to the control unit 10, the activation unit 20, and the display unit 40. The battery-type automatic fire extinguishing apparatus according to the present embodiment includes a first battery part 31 and a second battery part 32 as the battery part 30. The first battery unit 31 and the second battery unit 32 are switched by the battery switching unit 70, and power is supplied from the first battery unit 31 or the second battery unit 32.
The second battery unit 32 does not supply power before switching from the first battery unit 31 to the second battery unit 32, and after switching from the first battery unit 31 to the second battery unit 32, the control unit 10. , Power is supplied to the activation unit 20 and the display unit 40.
In this way, by supplying power alternatively from the first battery unit 31 or the second battery unit 32, the reliability of the device is improved. In the present embodiment, since the power supply by the second battery unit 32 is not performed before the switching from the first battery unit 31 to the second battery unit 32, the remaining amount of the second battery unit 32 before the switching is not increased. The decrease can be considered only due to spontaneous discharge.

  In addition, the 1st battery part 31 and the 2nd battery part 32 are each comprised by the single or several lithium battery. When the 1st battery part 31 and the 2nd battery part 32 are each comprised with the lithium battery of the same capacity | capacitance, electric power supply can be performed over a long period of time by the low power consumption of the whole apparatus.

The control unit 10 includes a capacity check unit 50, a disconnection check unit 60, and a battery switching unit 70. The control unit 10 activates the activation unit 20 when the sensing unit 4 detects a fire, and also displays the display unit 40. Indication of fire occurrence at.
The capacity check unit 50 measures the remaining amount of the battery unit 30. The remaining amount of the first battery unit 31 is measured every time set in the timer unit 51, and is measured, for example, at a 25-hour cycle. Further, the remaining amount measurement of the second battery unit 32 is performed when the power supply is switched from the first battery unit 31 to the second battery unit 32. In the present embodiment, after switching from the first battery unit 31 to the second battery unit 32, the remaining amount of the second battery unit 32 is not measured, and after switching to the second battery unit 32, the device By restricting the operation to the minimum necessary function maintenance, power consumption is suppressed and the rate of decrease in the remaining amount of the second battery unit 32 is delayed.
The disconnection check unit 60 detects the disconnection of the wiring 6 between the control unit 10 and the sensing unit 4 and the wiring 6 between the control unit 10 and the activation unit 20. Here, the disconnection is checked based on the presence or absence of current.
The battery switching unit 70 measures that the remaining capacity of the first battery unit 31 has fallen below the set value by the capacity check unit 50 and that the remaining amount of the second battery unit 32 has exceeded the set value. Then, the power supply to the control unit 10, the activation unit 20, and the display unit 40 is switched from the first battery unit 31 to the second battery unit 32. When it is measured that the remaining amount of the second battery unit 32 is below the set value, the battery switching unit 70 does not switch from the first battery unit 31 to the second battery unit 32, and the first battery unit The power supply by 31 continues, and the display unit 40 displays that the remaining battery level is low. Therefore, even if a situation occurs in which the remaining amount of the second battery unit 32 is lower than the set value for some reason before the remaining amount of the first battery unit 31 falls below the set value, By supplying power, maintenance of the automatic fire extinguishing function and alerting of battery replacement can be performed for a certain period of time. In addition, what is necessary is just to each determine the setting value of the residual amount of the 1st battery part 31 and the 2nd battery part 32 in consideration of the electric power required in order to maintain the function of an apparatus. For example, when the initial battery capacities of the first battery unit 31 and the second battery unit 32 are the same 6.0V and the power required to maintain the function of the device is about 3.3V, Is set to 4.0V.

The display unit 40 includes a battery display unit 41, an abnormality display unit 42, a fire display unit 43, and a power supply display unit 44.
The battery display unit 41 displays that the remaining battery level is low when the battery switching unit 70 switches the power supply from the first battery unit 31 to the second battery unit 32. Alternatively, since it is measured that the remaining amount of the second battery unit 32 is lower than the set value, the switching from the first battery unit 31 to the second battery unit 32 by the battery switching unit 70 is not performed, and the first battery When the power supply from the unit 31 is continued, it is displayed that the remaining battery level is low. In addition, it is preferable to make it easy to notice the surroundings by turning on or blinking the LED lamp. More preferably, a sound output unit is provided and linked with a sound alarm such as a buzzer or voice.
When the disconnection check unit 60 detects a disconnection of the sensing unit 4 or the activation unit 20, the abnormality display unit 42 notifies the surroundings of the abnormality by lighting or blinking the LED lamp. In this case as well, it is preferable to link the alarm with sound generated by the sound output unit.
The fire display unit 43 is used when only one of the first sensing unit 4a and the second sensing unit 4b senses a fire, or when both the first sensing unit 4a and the second sensing unit 4b sense a fire. indicate. Here, when only one of the first sensing unit 4a or the second sensing unit 4b senses a fire, the LED lamp blinks, and both the first sensing unit 4a and the second sensing unit 4b sense a fire. In some cases, it is preferable to distinguish between the two by, for example, turning on an LED lamp. Also in this case, it is preferable to link with an alarm by sound generated by the sound output unit.
The power display unit 44 displays that the power is supplied from the first battery unit 31 or the second battery unit 32 with an LED lamp or the like. In this case, it is preferable to make the LED lamp blink at an interval of about once every 10 seconds, rather than lighting the LED lamp.

FIG.4 and FIG.5 is a flowchart which shows the processing flow of the control system of the battery type automatic fire extinguishing apparatus.
From Step 1 to Step 14, the first battery unit 31 supplies power to the control unit 10, the activation unit 20, and the display unit 40, and the second battery unit 32 does not supply power.
In step 1, when the power is normally supplied from the first battery unit 31, it is displayed that the power is being supplied by, for example, the LED lamp of the power supply display unit 44 blinking at a predetermined interval. (Step 2).

In step 3, when a fire is detected by both the first sensing unit 4a and the second sensing unit 4b, the control unit 10 activates the activation unit 20, and the fire display unit 43 turns on an LED lamp to cause a fire. Is displayed (step 4). When the activation unit 20 is activated by the control unit 10, the activation unit 20 breaks the sealing plate of the pressure cylinder 7. Then, the fire extinguishing agent in the tank 2 is radiated from the nozzle 3 together with the gas enclosed in the pressurized cylinder 7 (step 5).
In step 3, when the control unit 10 does not detect the fire in both the first sensing unit 4a and the second sensing unit 4b, the presence or absence of fire detection in either the first sensing unit 4a or the second sensing unit 4b Is determined (step 6).
If a fire is detected in either the first sensing unit 4a or the second sensing unit 4b in step 6, an indication that there is a possibility of a fire is caused by the LED lamp of the fire display unit 43 blinking or the like. (Step 7). Then, if the other sensing unit 4 that has not sensed the fire thereafter senses a fire, it proceeds to step 4 and step 5.
In step 6, when both the first sensing unit 4a and the second sensing unit 4b do not sense a fire, the control unit 10 determines whether or not a predetermined time has passed by the timer unit 51 or the like (step 8).
If it is determined in step 8 that the predetermined time has not elapsed, step 3 is executed.
In step 8, if the predetermined time has elapsed, the disconnection check unit 60 detects whether the first sensing unit 4a, the second sensing unit 4b, and the activation unit 20 are disconnected (step 9).
In step 9, when a disconnection is detected in any of the first sensing unit 4a, the second sensing unit 4b, and the activation unit 20, an abnormality is displayed by turning on the LED lamp of the abnormality display unit 42 or the like. (Step 10). In this case, it is preferable to display the abnormality after confirming twice or three times instead of displaying the abnormality immediately after the disconnection is first detected, so that false alarms can be prevented.
In step 9, when no disconnection is detected in any of the first sensing unit 4a, the second sensing unit 4b, and the activation unit 20, the capacity check unit 50 sets the remaining amount of the first battery unit 31 to the first set value. It is determined whether or not this is the case (step 11). Here, the first set value is, for example, 5.0V.
If it is determined in step 11 that the remaining amount of the first battery unit 31 is greater than or equal to the first set value, step 3 is performed.
In step 11, when the remaining amount of the first battery unit 31 is measured to be less than the first set value,
The power supply from the first battery unit 31 is continued, and the capacity check unit 50 determines whether or not the remaining amount of the first battery unit 31 is greater than or equal to the second set value (step 12). Here, the second set value is, for example, 4.0V. Further, when the remaining amount of the first battery unit 31 is measured to be less than the first set value, it is displayed that the battery needs to be replaced by blinking the LED lamp of the battery display unit 41 (step 13). ). By providing the first set value and the second set value in this way, it is possible to notify the surroundings that the remaining amount of the battery unit 30 is decreasing before switching the power supply to the second battery unit 32. . In this case, when the remaining amount of the first battery unit 31 is detected to be less than the first set value, the measurement is repeated a plurality of times, and when less than the first set value is detected a plurality of times, the process proceeds to step 12 and step 13. It can prevent malfunction.
In step 12, when the remaining amount of the first battery unit 31 is measured to be equal to or greater than the second set value, step 3 is performed.
If it is determined in step 12 that the remaining amount of the first battery unit 31 is less than the second set value, the capacity check unit 50 determines whether the remaining amount of the second battery unit 32 is greater than or equal to the set value (step). 14). In this case, when the remaining amount of the first battery unit 31 is detected to be less than the second set value, the measurement is repeated a plurality of times, and when detected less than the second set value for a plurality of times, the operation proceeds to step 14 to cause a malfunction. Can be prevented.
In step 14, when the remaining amount of the second battery unit 32 is measured to be equal to or greater than the set value, the battery switching unit 70 switches the power supply from the first battery unit 31 to the second battery unit 32 (step 15).

  In step 15, after the power supply is switched from the first battery unit 31 to the second battery unit 32 by the battery switching unit 70, the power to the control unit 10, the activation unit 20, and the display unit 40 is supplied to the second battery unit. 32 (step 16), the first battery unit 31 does not supply power. While the power is normally supplied from the second battery unit 32, it is displayed that the power is being supplied, for example, the LED lamp of the power supply display unit 44 blinks at a predetermined interval (step). 17), it is displayed that the battery needs to be replaced by blinking the LED lamp of the battery display unit 41 (step 18).

On the other hand, in step 19, when both the first sensing unit 4a and the second sensing unit 4b sense a fire, the control unit 10 activates the activation unit 20, and the fire display unit 43 turns on the LED lamp. The occurrence of a fire is displayed (step 20). When the activation unit 20 is activated by the control unit 10, the activation unit 20 breaks the sealing plate of the pressure cylinder 7. Then, the fire-extinguishing agent in the tank 2 is radiated from the nozzle 3 together with the gas enclosed in the pressurized cylinder 7 (step 21).
In step 19, if the control unit 10 does not detect the fire in both the first sensing unit 4a and the second sensing unit 4b, the presence or absence of fire detection in either the first sensing unit 4a or the second sensing unit 4b Is determined (step 22).
If a fire is detected in either the first sensor 4a or the second sensor 4b in step 22, an indication that there is a possibility of a fire is caused by, for example, the LED lamp of the fire display 43 blinking. (Step 23). If a fire is detected by the other sensing unit 4 that has not sensed a fire after that, the process proceeds to step 20 and step 21.
In step 22, when both the first sensing unit 4a and the second sensing unit 4b do not sense a fire, the control unit 10 determines whether or not a predetermined time has passed by the timer unit 51 or the like (step 24).
If it is determined in step 24 that the predetermined time has not elapsed, step 19 is executed.
If the predetermined time has passed in step 24, the disconnection check unit 60 detects the presence or absence of disconnection of the first sensing unit 4a, the second sensing unit 4b, and the activation unit 20 (step 25).
If disconnection is detected in any of the first sensing unit 4a, the second sensing unit 4b, and the activation unit 20 in step 25, an abnormality is displayed, for example, by turning on the LED lamp of the abnormality display unit 42. (Step 26). In this case, if a disconnection is detected, measurement is repeated a plurality of times, and if a disconnection is detected a plurality of times, an error is displayed to prevent false reports.
If no disconnection is detected in any of the first sensing unit 4a, the second sensing unit 4b, and the activation unit 20 in Step 25, Step 19 is performed.

As described above, according to the present embodiment, there are two main and secondary power systems, and the function of the device is maintained for a certain period of time by the secondary system battery even when the remaining battery level of the main system falls below the set value. Therefore, it is possible to prevent a situation in which the device is stopped due to the battery being exhausted without noticing the battery exhaustion alarm, and the device does not operate when a fire occurs.
For example, when the first battery unit 31 and the second battery unit 32 are each composed of one lithium ion primary battery having the same capacity (6V, 2400 mAh), the lifetime of the battery unit 30 is calculated as follows. The

  First, the lifetime of the first battery unit 31 is calculated. Since the power consumption at the time of monitoring is 21.73 μAh, the converted value per year is 21.73 μAh × 24 hours × 365.25 days = 190.49 mAh. Moreover, the power consumption at the time of inspection (power consumption in the inspection once / year) is 0.08 mAh. In addition, the battery capacity is 2400 mAh, but the threshold setting for the start-up ensuring voltage is considered as 10% based on the lithium battery characteristics when calculating the lifetime. Therefore, the lifetime of the first battery unit 31 is 2400 × 0.9 / (190.49 + 0.08) = 11.33 years.

  Next, the lifetime of the second battery unit 32 after the power supply is switched is calculated. Since the power consumption at the time of monitoring is 21.73 μAh, the converted value per year is 21.73 μAh × 24 hours × 365.25 days = 190.49 mAh. Moreover, the power consumption at the time of inspection (power consumption in the inspection once / year) is 0.08 mAh. Further, since the power consumption of the alarm for notifying that the remaining battery level is low is 75 μAh per hour, the converted value per year is 75 μAh × 24 hours × 365.25 days = 657.45 mAh. . Further, since the self-discharge is 1% / year, the battery capacity is 2400 mAh × 0.8867 = 2128 mAh when switching after 11.33 years.
