Description

[Technical Field]

[0001] The present invention relates to a fire monitoring system. [Background technology]

[0002] Conventionally, there is a fire alarm system equipped with a fire detector that is installed at a garbage station located on the premises of a building such as an apartment building. Because combustible garbage is accumulated at the garbage station, fires may occur due to arson or the like, and installing the fire detector at the garbage station makes it possible to detect fires (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-296836 Summary of the Invention [Problem to be solved by the invention]

[0004] Garbage stations are not only located on the premises of buildings, but are also set up in designated locations in residential areas and other urban areas, and just like the garbage stations located on the premises of buildings, there is a possibility of fires occurring due to arson, etc. Therefore, it is desirable to install fire detectors at garbage stations in urban areas as well to monitor for fires.

[0005] On the other hand, conventional fire detectors receive the power required to operate from a commercial power source. At garbage stations located in urban areas, it may be difficult to secure a commercial power source, making it difficult to install conventional fire detectors as they are.

[0006] It is possible to install solar panels and generate electricity to power the fire detectors, but the amount of electricity generated by solar panels depends on the amount of sunlight received, so if the garbage station is installed in a shady location or in a place that is prone to getting dirty with dust, it will be difficult to provide a stable power supply.

[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a fire monitoring system that can provide a more stable power supply even when installed in a location where it is difficult to supply power from a commercial power source. [Means for solving the problem]

[0008] The present invention is a fire monitoring system comprising a fire detection unit and a power supply unit that supplies power to the fire detection unit, the power supply unit having a water battery and a water storage unit for supplying water to the water battery, the water storage unit being configured to be able to store water.

[0009] In the present invention, the water storage section may be connected to an overflow path as an overflow. Also, in the present invention, the fire detection section may further include an ultraviolet irradiation section. Also, in the present invention, a wireless communication section may be further included, and the fire monitoring system may be configured to be able to communicate with an information terminal located in the area where the fire monitoring system is installed via the wireless communication section. Also, in the present invention, the water storage section may include a tank section for storing water and a lid section that allows water to be introduced into the tank section. [Effects of the Invention]

[0010] In the present invention, the power supply unit that supplies power to the fire detection unit has a water battery, so it is possible to provide a fire monitoring system that can provide a more stable power supply even when installed in a location where it is difficult to supply power from a commercial power source. [Brief explanation of the drawings]

[0011] [Figure 1] 1 is a side schematic view of an embodiment of the present invention. [Figure 2] FIG. 1 is a block diagram of an embodiment of the present invention. [Figure 3] FIG. 2 is a schematic diagram illustrating a fire detection process according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] An embodiment of the present invention will be described with reference to Figures 1 to 3. Fire monitoring system 1 includes a fire detection unit 2 and a power supply unit 3. In this embodiment, it further includes a wireless communication unit 4. Fire monitoring system 1 is provided with a base 5, and can be fixed via base 5 to a location near the object to be monitored, such as a utility pole P near a garbage station G, a fence, or a rain gutter.

[0013] The fire detection unit 2 is provided to detect fires. The fire detection unit 2 is connected to the power supply unit 3 and is configured to receive power from the power supply unit 3. The fire detection unit 2 is also provided with various sensors for detecting fires. In this embodiment, the fire detection unit 2 has a flame detection unit 6, which is covered with a light-shielding cover 7. The fire detection unit 2 is also fixed to the base 5 via a mounting base 8.

[0014] The configuration of the flame detection unit 6 can be appropriately adapted from the configuration of a known flame detector, but for example, the flame detection unit 6 has a light receiving element 9 that serves as a flame sensor and is capable of detecting light L of a wavelength, such as infrared or ultraviolet light, emitted by a fire flame F. The number of light receiving elements 9 may be one, but it is also possible to provide multiple light receiving elements 9 that can detect light of different wavelengths, which makes it possible to reduce false detections caused by sunlight, electric lights, etc.

[0015] In this embodiment, the fire detection unit 2 further includes a light irradiating unit. The light irradiating unit is configured to irradiate light in a wavelength range that is invisible to humans but visible to birds and other animals, especially crows, such as ultraviolet light, especially near-ultraviolet light, and is provided as an ultraviolet light irradiating unit 10 in this embodiment.

[0016] At the garbage station G, damage can occur when crows and other birds rummage through the garbage, scattering it everywhere. However, by providing the ultraviolet ray irradiation unit 10, the crows and other birds will be put off by ultraviolet rays, making it possible to reduce the damage. When the ultraviolet ray irradiation unit 10 is provided, it is preferable that the flame detection unit 6 be capable of detecting infrared rays to prevent false detection. The ultraviolet ray irradiation unit 10 can also be provided in a location separate from the fire detection unit 2.

[0017] The timing of irradiating ultraviolet rays from the ultraviolet irradiating unit 10 may be constant or may be arbitrary timing. For example, the arbitrary timing may be irradiating at regular intervals, or irradiating when an infrared sensor such as the light receiving element 9 of the flame detecting unit 6 detects something that appears to be a crow or the like.

[0018] It is preferable to provide a timer, optical sensor, etc. in the ultraviolet irradiating unit 10 so that the irradiation of ultraviolet rays is stopped at night. By doing so, it is thought that damage is less likely to occur at night because crows and other insects that normally rummage through garbage are dormant at night, but it is also possible to prevent insects that are active at night, such as moths and winged insects, from gathering because they react to ultraviolet rays.

[0019] The power supply unit 3 has a water battery 11 and a water storage unit 12. The water battery 11 is a battery that generates electromotive force when water is supplied, and is, for example, a primary battery with a copper positive electrode and a magnesium negative electrode, stacked in the order of positive electrode, catalyst, separator, and negative electrode (the catalyst and separator may be alternately composed of multiple layers).

[0020] The water storage section 12 is provided to be able to store water and to supply water to the water cell 11. In this embodiment, the water storage section 12 is provided to be able to store rainwater W, and has a lid section 13 and a tank section 14.

[0021] The lid 13 is provided so that rainwater W and other water can be introduced into the tank 14. In this embodiment, the lid 13 is formed in a lattice shape to prevent dust from entering the tank 14. That is, in this embodiment, the lid 13 also serves as a dust filter.

[0022] Tank section 14 is provided to store rainwater W or other water introduced through lid section 13, and is connected to flow path 15 that supplies stored water to water cell 11. Flow path 15 is preferably configured to supply water from tank section 14 to water cell 11 intermittently, for example, by dripping. Of course, when there is a shortage of rainwater W due to a period of good weather, or when fire monitoring system 1 is installed indoors, it is also possible to replenish tank section 14 with water separately from lid section 13. Tap water or other water (including non-potable water) can be used as the water.

[0023] Furthermore, the water storage section 12 is provided with an overflow path (not shown) to allow a certain amount of water to overflow so as to prevent excessive water supply to the water cell 11. The capacity of the tank section 14 may be adjusted to prevent excessive water supply, and the overflow path may be provided as needed.

[0024] The wireless communication unit 4 is provided to enable the fire monitoring system 1 to communicate via the wireless communication unit 4 with information terminals T, such as electronic information terminals such as smartphones and personal computers, IoT terminals such as smart speakers, and various alarm devices, such as residential fire alarms capable of wireless communication, located within the area in which the fire monitoring system 1 is installed, for example, within the area under the jurisdiction of the neighborhood association or town council that manages the garbage station G.

[0025] In this embodiment, the wireless communication unit 4 is configured to be able to communicate with the information terminal T via a base station B installed in the area or in a nearby area. Note that the communication between the wireless communication unit 4, the base station B, and the information terminal T may be either one-way communication or two-way communication, and can be selected appropriately.

[0026] The fire monitoring system 1 is configured so that when the fire detection unit 2 detects a fire, it can transmit fire information to the information terminal T via the wireless communication unit 4. Note that it may also be possible to transmit information other than fire information; for example, a water detection sensor may be provided in the water storage unit 12, and upon detecting that a predetermined amount of water has run out, a message urging the water storage unit 12 to be filled with water may be transmitted.

[0027] When water such as rainwater W is supplied to the water storage section 12 (in this embodiment, the tank section 14), the water is supplied to the water battery 11 via the flow path 15, thereby providing power to the fire detection section 2. The fire detection section 2 uses this power to operate various sensors continuously or intermittently, and monitors the monitoring target, for example, a garbage station.

[0028] When the fire detection unit 2 detects a fire, it transmits that information to an information terminal T located within the area via the wireless communication unit 4. Residents of the area who have checked the information terminal T can go to the scene, confirm whether a fire has occurred, and take appropriate measures, such as extinguishing the fire in its initial stage or reporting it to the fire department.

[0029] Therefore, in the fire monitoring system 1 of this embodiment, power is supplied to the fire detection unit 2 by a water battery 11, making it possible to supply more stable power even when the system is installed in a location where it is difficult to supply power from a commercial power source, such as a garbage station G in the city.

[0030] Although the present invention has been described based on the above embodiment, the present invention is not limited to the above embodiment and can be modified as appropriate within the scope of the invention.

[0031] (1) In the above embodiment, the explanation was given assuming that the device would be installed at a garbage station G located in the city, but the installation location is not limited to a garbage station G located in the city, and the device can be installed outside a garbage station on the premises of a building, or in various other locations where fire monitoring is required.

[0032] (2) In the above embodiment, the fire detection unit 2 has a flame detection unit 6, but it is also possible to provide a smoke detection unit (not shown) that detects smoke generated by a fire and / or a heat detection unit (not shown) that detects heat generated by a fire instead of or in addition to the flame detection unit 6.

[0033] The smoke detection unit may be configured to have a known smoke detector, such as a dark box and a light-emitting element and a light-receiving element provided in the dark box. The heat detection unit may be configured to have a known heat detector, such as a thermistor.

[0034] (3) A backup power source (not shown), such as a dry cell battery, may be provided in the fire monitoring system 1. When the amount of water in the water storage unit 12 falls below a certain level, the backup power source is switched to and a message is sent to the information terminal T urning the water storage unit 12, thereby preventing the fire monitoring system 1 from shutting down unexpectedly.

[0035] (4) The fire monitoring system 1 may be provided with an imaging means (not shown). For example, by recording images before and after the fire breaks out, if the fire is suspected to be caused by a suspicious fire, the cause can be easily identified. In addition, the timing for irradiating ultraviolet light by the ultraviolet light irradiation unit 10 may be set to only when the imaging means detects a crow or the like, thereby reducing power consumption. A visible light camera, an infrared camera, or the like can be appropriately adopted as the imaging means.

[0036] (5) The fire monitoring system 1 may be provided with an audio means (not shown) so that when a fire or other incident occurs, the occurrence is notified to those in the vicinity by audio (such as an alarm sound such as a siren or an alarm message). [Explanation of symbols]
