Abstract
Official abstract text for this publication.
A flood sensor includes a notification unit that notifies of detection of flooding, and a primary battery. The primary battery includes a positive electrode, a negative electrode, and a separator that is disposed between the positive electrode and the negative electrode and to which an electrolyte adheres. When the separator is flooded, the electrolyte is dissolved in water to form an electrolyte solution, and the primary battery starts generating power to supply power necessary for driving the notification unit.
First claim
Opening claim text (preview).
1 . A flood sensor comprising: a notification unit that notifies of detection of flooding; and a primary battery, wherein the primary battery includes a positive electrode, a negative electrode, and a separator that is disposed between the positive electrode and the negative electrode and to which an electrolyte adheres, and when the separator is flooded, the electrolyte is dissolved in water to form an electrolyte solution, and the primary battery starts generating power to supply power necessary for driving the notification unit. 2 . The flood sensor according to claim 1 , further comprising a plurality of primary batteries connected in series. 3 . The flood sensor according to claim 1 , further comprising a detection sensor provided above the primary battery, wherein the detection sensor includes a positive electrode, a negative electrode, and a separator that is disposed between the positive electrode and the negative electrode and to which an electrolyte adheres, and the notification unit notifies that flooding is occurring at a height of the primary battery in a vertical direction when driven by the power supplied from the primary battery, and notifies that flooding is occurring at a height of the detection sensor in the vertical direction when power generation due to flooding of the separator of the detection sensor is detected after driving with the power supplied from the primary battery. 4 . The flood sensor according to claim 1 , wherein the negative electrode is formed of one or more metals selected from magnesium, zinc, aluminum, and iron, or an alloy containing, as a main component, one or more metals selected from magnesium, zinc, aluminum, and iron. 5 . The flood sensor according to claim 1 , wherein the separator is formed of an insulator having water absorbency. 6 . A notification system comprising: the flood sensor according to claim 1 ; and a notification server that is connected to the flood sensor and refers to a position and a height of the flood sensor, wherein the notification unit of the flood sensor notifies of flooding of the flood sensor, and the notification server determines an importance of an alarm according to the position and the height of the flood sensor that has notified of flooding. 7 . The notification system according to claim 6 , wherein the notification server determines the importance of the alarm according to the number of the flood sensors that notify of occurrence of flooding. 8 . The notification system according to claim 6 , wherein the notification server further determines the importance of the alarm according to a precipitation amount at a position where the flood sensor is installed. 9 . The flood sensor according to claim 2 , wherein the negative electrode is formed of one or more metals selected from magnesium, zinc, aluminum, and iron, or an alloy containing, as a main component, one or more metals selected from magnesium, zinc, aluminum, and iron. 10 . The flood sensor according to claim 3 , wherein the negative electrode is formed of one or more metals selected from magnesium, zinc, aluminum, and iron, or an alloy containing, as a main component, one or more metals selected from magnesium, zinc, aluminum, and iron. 11 . The flood sensor according to claim 2 , wherein the separator is formed of an insulator having water absorbency. 12 . The flood sensor according to claim 3 , wherein the separator is formed of an insulator having water absorbency. 13 . The flood sensor according to claim 4 , wherein the separator is formed of an insulator having water absorbency. 14 . A notification system comprising: the flood sensor according to claim 2 ; and a notification server that is connected to the flood sensor and refers to a position and a height of the flood sensor, wherein the notification unit of the flood sensor notifies of flooding of the flood sensor, and the notification server determines an importance of an alarm according to the position and the height of the flood sensor that has notified of flooding. 15 . A notification system comprising: the flood sensor according to claim 3 ; and a notification server that is connected to the flood sensor and refers to a position and a height of the flood sensor, wherein the notification unit of the flood sensor notifies of flooding of the flood sensor, and the notification server determines an importance of an alarm according to the position and the height of the flood sensor that has notified of flooding. 16 . A notification system comprising: the flood sensor according to claim 4 ; and a notification server that is connected to the flood sensor and refers to a position and a height of the flood sensor, wherein the notification unit of the flood sensor notifies of flooding of the flood sensor, and the notification server determines an importance of an alarm according to the position and the height of the flood sensor that has notified of flooding. 17 . A notification system comprising: the flood sensor according to claim 5 ; and a notification server that is connected to the flood sensor and refers to a position and a height of the flood sensor, wherein the notification unit of the flood sensor notifies of flooding of the flood sensor, and the notification server determines an importance of an alarm according to the position and the height of the flood sensor that has notified of flooding. 18 . The notification system according to claim 7 , wherein the notification server further determines the importance of the alarm according to a precipitation amount at a position where the flood sensor is installed.
