Description

The present invention relates to a disaster warning system.

Heavy rains such as torrential downpours and localized torrential downpours often result in flooding of houses. On the other hand, a breaker that detects the occurrence of water intrusion and shuts off electricity is described in Patent Document 1. In addition, if a leakage occurs due to flooding, the leakage breaker will shut off the electricity, so the risk of fire due to flooding of the house is low. However, after the water has subsided from inside the house, an electrical fire may occur when a resident reenergizes the house during a power outage. The technology described in Patent Document 1 does not protect against such electrical fires.

In addition, heavy rains often cause landslides and mudslides on the hills behind houses, causing a lot of damage to houses and residents. Patent Document 2 discloses installing a landslide sensing means on a back mountain or the like in order to deal with landslides and landslides. In this way, it may be possible to detect the occurrence of a landslide, but in cases where the owner of the house and the mountain behind the house are different, it is difficult to install a detection means, and it is difficult to prevent damage to the house and residents from landslides. difficult.

It is a figure which shows the different example which took countermeasures against flood damage using a disaster warning system. FIG. 2 is a diagram showing an example of taking measures against fire using a disaster warning system. FIG. 2 is a diagram showing an example of taking measures against landslides using a disaster warning system.

A mode for carrying out the invention will be shown below. The disaster warning system 1 of this embodiment includes an alarm device 2 in a house 8 that predicts a disaster to the house 8 and outputs a warning. An example of this disaster warning system 1 includes a sensor unit that is installed at least one inside the house 8 or around the house 8 and detects an event that occurs to the house 8, and a sensor unit that detects an event that occurs to the house 8. It is equipped with a calculation section 21 that determines the risk of disaster, and an output section 22 that outputs the determination result of the calculation section 21, and the sensor section includes a flood sensor 31 that detects that rain or water has accumulated to a certain depth. The calculation unit 21 is composed of a disaster-related event sensor that detects events related to disasters that increase the risk of occurrence due to rain or water accumulating to a certain depth, and the calculation unit 21 uses information sent from the flood sensor 31. The risk of disaster to the house 8 is determined by combining the information sent from the disaster-related event sensor and the information sent from the disaster-related event sensor. Therefore, it is possible to provide a more complete warning than before for disasters caused by a large amount of water on the house 8.

Further, in another example of the disaster warning system 1 of the embodiment, a sensor unit that is installed at least one inside the house 8 or around the house 8 and detects an event that occurs to the house 8, and a sensor unit that detects an event occurring in the house 8, and a sensor unit that is installed in at least one of the house 8 or around the house 8, and A communication unit 23 that receives disaster-related information that is information about the situation and the occurrence of a disaster, and a calculation unit 21 that determines the risk of disaster to the house 8 based on the information obtained from the sensor unit and the information obtained from the communication unit 23. and an output section 22 that outputs the determination result of the calculation section 21.The sensor section is composed of a flood sensor 31 that detects rain or water accumulated to a certain depth. The disaster risk to the house 8 is determined by combining the information sent from the communication unit 23 with the disaster-related information received by the communication unit 23. Therefore, it is possible to provide a more complete warning than before for disasters caused by a large amount of water on the house 8.

These disaster warning systems 1 are systems 1 that predict disasters to houses 8 due to heavy rain, etc., and issue warnings. Disasters to house 8 due to heavy rain, etc., include flood damage to house 8, landslides due to increased moisture content in the soil around house 8, fire that occurs when house 8 is flooded, and flood damage to house 8. These are flood damage to the house 8 itself or disasters related to the flood damage to the house 8, such as a fire caused by electricity when the power is turned on again after a power outage occurs.

In this system 1, information obtained from a flood sensor 31 that detects the occurrence of flooding of a house 8 constituting a sensor unit, and information obtained from other sensors or disaster-related information are combined, Predicts a disaster to the house 8 and outputs a warning.

This system 1 includes an alarm device 2 that has at least a calculation section 21 that receives information from a sensor section and an output section 22 that outputs a determination result of the calculation section 21. At least one of the sensors constituting the sensor section is a flood sensor 31 that detects prediction or occurrence of flood damage to the house 8. The flood sensor 31 that predicts or detects the occurrence of flood damage to the house 8 may be any sensor that detects rain or water accumulation up to a certain height, and may be a flood sensor, a water level sensor, a water detection sensor, etc. There may be.

In addition to the flood sensor 31 that predicts or detects the occurrence of flood damage to the house 8, the sensor unit also includes sensors related to disasters that increase the risk of occurrence due to rain or water accumulating to a certain depth. It may also include a disaster-related event sensor that detects events. More specifically, a sensor capable of predicting or detecting the occurrence of a disaster to the house 8 may be separately provided. For example, a sensor 34 (ultrasonic sensor, Doppler sensor, sound sensor, seismic sensor, etc.) that monitors signs of a landslide, a sensor that monitors the state of the electrical system of the house 8 and detects signs of a fire (insulation deterioration detection sensors, current sensors, voltage sensors, disconnection detection sensors, tracking detection sensors, etc.). Furthermore, by providing a plurality of these sensors, the accuracy of disaster prediction and occurrence detection may be improved.

As understood from the illustration in FIG. 1 , the alarm device 2 can include a communication section 23 . The communication unit 23 is a part through which the alarm device 2 communicates with the outside. The communication department 23 communicates with external parties to receive weather warnings and advisories from the Japan Meteorological Agency, evacuation information (warning levels, etc.) from the Ministry of Land, Infrastructure, Transport and Tourism and local governments, and hazard maps (estimated inundation depth, risk of landslides, etc.). ) and other disaster-related information can be received from outside. Alternatively, the communication unit 23 may receive signals from a device or device provided separately from the alarm device 2. For example, a signal related to the determination result of the calculation unit 21 may be transmitted to an audio device provided separately from the alarm device 2, and a sound may be output from the audio device to notify the prediction or occurrence of a disaster to the house 8.

The calculation unit 21 may determine the risk of disaster to the house 8 based on information sent from a plurality of sensors that constitute the sensor unit, or may determine the risk of disaster to the house 8 based on the information sent from the sensors and the communication unit 23. The risk of disaster to the house 8 may be determined from the disaster-related information received by the user.

The output unit 22 outputs the calculation result of the calculation unit 21. The output format may be sound, light, or signal output. The output by the output unit 22 may be different depending on the calculation result of the calculation unit 21. For example, when the calculation unit 21 expresses the risk of disaster to the house 8 in five levels, it is preferable that the output unit 22 outputs the five levels.

When the risk of disaster to the house 8 is high, it is preferable to output a warning to make the user aware of the danger. For example, you can increase the volume of the sound, increase the intensity of the light, or change the content of the output audio. Further, depending on the danger of disaster to the house 8, the power supply to the house 8 may be cut off by not only outputting a warning from the output unit 22 but also outputting a cutoff signal to a breaker.

As can be understood from the illustration in FIG. 1, the alarm device 2 of the embodiment includes a calculation section 21, an output section 22, and a communication section 23; however, it is not necessary to separate the functions into each section; It is also possible to provide the output section 22 with the function of the output section 22.

Note that there is a risk that the house 8 may experience a power outage due to flooding damage to the house 8. In preparation for such a case, the alarm device 2 is equipped with a power source (battery, generator, etc.) that is independent of the grid power supply of the house 8. etc.) is preferably provided. By doing so, the alarm device 2 can operate normally even during a power outage, predict further disasters to the house 8, and output a warning. Further, the alarm device 2 may include a storage section. Even if there is a time difference between the timing of information sent from a plurality of sensors or the timing of information sent from a sensor and disaster-related information sent from a communication section, the calculation section 21 can make a decision by combining the information. As such, it is preferable that the information sent from the sensor or the communication section 23 is stored in the storage section.

Here, an example of countermeasures against flood damage will be explained. Possible causes of flooding to the house 8 include flooding caused by the rise and overflow of rivers due to heavy rain, flooding caused by tsunamis brought about by heavy rain and typhoons, and large amounts of water flooding into the house 8 due to localized torrential rain. , the first water immersion sensor 31a detects danger, and then the second water immersion sensor 31b detects the occurrence. At this time, it is preferable that the first water immersion sensor 31a and the second water immersion sensor 31b are installed at different locations. For example, the installation locations may be different, such as inside the house 8 and outside the house 8, or both may be installed inside the house 8 or outside the house 8, but at different heights. By doing so, the first flood sensor 31a can determine that there is a risk of flood damage, and the second flood sensor 31b can determine that the risk of flood damage has increased or that flood damage has occurred. can be determined.

As a specific example, as can be understood from FIG. 2, a first flood sensor 31a is installed around the house 8. Further, a second flood sensor 31b is installed in the house 8 at a higher position than the first flood sensor 31a. In this case, when the first water immersion sensor 31a detects water immersion, it outputs a signal to the calculation unit 21. Thereafter, the calculation unit 21 determines that there is a risk of flooding to the house 8, and an alarm to the effect that there is a risk of flooding to the house 8 is issued from the output unit 22.

Further, when the second water immersion sensor 31b detects water immersion, it outputs a signal to the calculation unit 21. The calculation unit 21 determines that flooding has occurred in the house 8 based on the signals from both the first flood sensor 31a and the second flood sensor 31b, and the output unit 22 determines that flooding has occurred in the house 8. A warning will be issued. If signals are obtained from both the first flood sensor 31a and the second flood sensor 31b, the danger to the house 8, residents, etc. is higher, so a warning that clearly indicates the high danger is issued. It is preferable that the Further, in this case, since there is a risk of fire due to flooding of the house 8, a cutoff signal may be outputted from the output section 22 to the breaker to cut off the power supply.

In the example shown in FIG. 2, the first flood sensor 31a is installed around the house 8, but there is no need to limit it to such an embodiment. For example, as understood from FIG. 3, the first water immersion sensor 31a may be installed under the floor 81, and the second water immersion sensor 31b may be installed on the floor 81. Note that when multiple flood sensors 31 are installed, if the flood sensor 31 installed at the bottom does not detect water and another flood sensor 31 detects it, the calculation unit 21 will determine that it is a false detection. can be determined. In other words, by installing a plurality of water immersion sensors 31, it is possible to prevent false detection by the sensor section.

Here, an example of the water immersion sensor 31 that detects that rain or water has accumulated to a certain depth will be described. For example, it may be possible to detect that rain or water has accumulated to a certain depth (up to a reference height) by detecting that water has come into contact with the water immersion sensor 31 placed at a reference height. In this case, it is preferable to take measures to prevent malfunctions due to contact with water droplets, such as covering the periphery of the water immersion sensor 31. Moreover, it is provided with a plurality of electrodes having different lengths, and is installed with a voltage applied to the longer electrode. When rain or water accumulates due to heavy rain, etc., both the longer electrode and the shorter electrode are soaked in the rain or water, and voltage is applied to the shorter electrode, so continuity is detected. By doing so, it may be possible to detect that rain or water has accumulated to a certain depth (to the bottom end of the shorter electrode). Furthermore, if continuity of the shorter electrode can no longer be detected, it is possible to detect that rain or water has receded. In addition, the water level may be calculated from data obtained when waves emitted from the water immersion sensor 31 are reflected on the water surface and returned. In this case, water can be detected even if water does not come into contact with the water immersion sensor 31. As described above, any known method may be used for the water intrusion sensor 31 to detect that rain or water has accumulated to a certain depth.

Next, an example using disaster-related information will be described. Currently, the expected magnitude of damage in the event of a disaster such as heavy rain is provided by disaster-related information such as weather warnings and advisories from the Japan Meteorological Agency, evacuation information from the Ministry of Land, Infrastructure, Transport and Tourism and local governments, and hazard maps. To be announced. This disaster-related information includes disaster prediction information, such as how deep the house 8 and the area around the house 8 will be flooded due to a disaster, and how much there is a risk of landslides. The communication unit 23 of the alarm device 2 of the embodiment is configured to be able to receive these disaster-related information.

The disaster-related information received by the communication unit 23 is used by the calculation unit 21 to determine the risk of disaster occurrence. For example, if the flooding depth at the time of a disaster is such that the house 8 will not be flooded, the risk is "low", if the depth is below the floor, the risk is "medium", and if the water is below the floor level, the risk is "medium" In some cases, the risk is ``high.'' Note that since the reference depth differs depending on each house 8, information on the house 8 can be registered in the calculation unit 21 of the alarm device 2, so that the information on the house 8 can be included in the determination. It is preferable to do so.

The communication unit 23 may be configured to receive disaster-related information only around the house 8, or may receive disaster-related information in a wider area than the area around the house 8, and the calculation unit 21 extracts only the information around the house 8. You can do it like this.

In the embodiment, a flood sensor 31 is installed in addition to the communication unit 23 that receives disaster-related information. By installing the flood sensor 31 in the house 8, it is possible to detect that the house 8 has actually suffered flood damage. It is preferable to determine the installation height of the water immersion sensor 31 by taking into consideration information on the water immersion depth (inundation depth).

By combining disaster-related information and detection from the flood sensor 31 in this way, various advantages can be produced. For example, if the disaster-related information indicates that there is a risk of a disaster around the house 8 to the extent that the house 8 will not be flooded in the event of a disaster, the flood sensor 31 installed at a higher position than the height assumed by the disaster-related information If the system detects rain or water accumulation, it can tell that the flood damage is greater than expected.

On the other hand, if the disaster-related information indicates that there is a risk of flooding around the house 8 to a depth greater than the floor level in the event of a disaster, the flood sensor 31 can be installed at a position below the depth at which the house 8 will not be flooded. , flood damage to the house 8 can be detected at an early stage, and evacuation time can be secured.

Therefore, it is preferable that the calculation unit 21 calculates the recommended installation height of the water immersion sensor 31 and outputs it from the output unit 22. In other words, the installation height of the flood sensor 31 recommended by the calculation unit 21 may be calculated based on information about the house 8 registered in the calculation unit 21 of the alarm device 2 and disaster-related information in the area around the house 8. .

Next, a case will be described in which the present system 1 is used as a countermeasure against a fire caused when the house 8 is flooded and a fire caused by energization when the power is re-energized. When the house 8 is flooded due to heavy rain, the electrical systems such as electric wires, outlets, and home appliances wired to the house 8 are also flooded. When the electrical system is flooded, abnormalities occur in the electrical system such as a decrease in insulation resistance, increasing the risk of fire. If there is an abnormality in the electrical system, functions such as earth leakage breakers will cut off the power and create a power outage, reducing the risk of fire, but the abnormality in the electrical system will not be removed when the power is turned on again. There is a risk of fire.

Therefore, in the example described below, danger is detected using the water immersion sensor 31, an insulation deterioration detection sensor, and the like. The calculation unit 21 of the alarm device 2 receives a detection signal from a flood sensor 31 that detects the occurrence of flooding in the house 8, and a sensor 33 that monitors the state of the electrical system that detects an abnormality in the electrical system of the house 8 (insulation deterioration). Based on detection signals from detection sensors, current sensors, voltage sensors, etc.), the calculation unit 21 determines the risk of fire in the electrical system (particularly the risk of energization fire at the time of re-energization), and issues an alarm from the output unit 22. Output. In this way, the sensor unit includes a sensor 33 that monitors the state of the electrical system, and monitors the state of the electrical system and the information sent from the flood sensor 31 that detects that rain or water has accumulated to a certain depth. It is preferable that the calculation unit 21 determines the risk of fire to the house by combining the information sent from the sensor 33.

Note that if the alarm device 2 also goes into a power outage state in conjunction with the power outage state of the house 8, the detection by the sensor unit and the calculation by the calculation unit 21 will not be performed normally. It is preferable to install a power source (such as a battery or a generator) that is independent from the By doing so, even after a power outage occurs due to flooding of the house 8, the risk of fire in the electrical system can be determined.

In the case of a fire due to energization during re-energization, human actions are involved in re-energizing, such as turning on the breaker, inserting the plug into the outlet, and turning on the power to home appliances. Therefore, the alarm device 2 may include a human sensor that detects human motion and heat. In this case, when the detection signal from the flood sensor 31, the detection signal from the sensor 33 that monitors the state of the electrical system, and the detection signal from the human sensor are obtained, the calculation unit 21 of the alarm device 2 Preferably, it is determined that there is a risk of energization fire, and the output unit 22 outputs a warning to that effect.

In the example shown in FIG. 4, a flood sensor 31 is installed to detect subfloor flooding of the house 8, and a sensor 33 is installed on the distribution board 91 in the house 8 to monitor the state of the electrical system. The sensor 33 that monitors the state of the electrical system is an insulation deterioration detection sensor, etc., and in this example, it constantly measures insulation resistance and detects a decrease in insulation resistance to detect an abnormality in the electrical system. ing. The sensor 33 that monitors the state of the electrical system is not limited to an insulation deterioration detection sensor, and may be, for example, a current sensor, a voltage sensor, a disconnection detection sensor, a tracking detection sensor, or the like. In this case, current values, voltage values, etc. may be constantly measured to detect abnormalities in the electrical system.

Note that when under-floor flooding occurs in the house 8 due to heavy rain or the like, a detection signal from the flooding sensor 31 is sent to the calculation unit 21, thereby detecting that under-floor flooding has occurred. Thereafter, when a signal indicating that an abnormality in the electrical system has been detected is sent from the sensor 33 that constantly monitors the state of the electrical system to the calculation unit 21, the calculation unit 21 determines that there is a risk of fire due to flooding of the house 8. It is only necessary to determine this and output it from the output unit 22.

Next, an example of use in countermeasures against landslides will be explained. Due to heavy rain, the amount of moisture in the soil around the house 8 increases, and as the amount of moisture in the soil increases, the risk of occurrence of landslide disasters such as landslides and landslides increases. In a house 8 located near a place where a landslide is likely to occur, the flood sensor 31 installed around the house 8 detects that the land around the house 8 is in a state where it cannot absorb any more rain or water. , it can be seen that the amount of water in the soil is increasing. Therefore, when the inundation sensor 31 detects water, the output unit 22 may output a message indicating that there is a risk of landslide.

Furthermore, when information is sent to the alarm device 2 from the sensor 34 that monitors for signs of a landslide, the signal detected by the flood sensor 31 and the signal detected by the sensor 34 that monitors for signs of a landslide are obtained. The calculation unit 21 determines that a landslide has occurred. In a situation where this determination is made, the output unit 22 may output that a landslide has occurred. In this way, the sensor unit 3 includes a sensor 34 that monitors signs of landslides around the house 8, and receives information sent from the flood sensor 31 that detects rain or water that has accumulated to a certain depth, and It is preferable that the calculation unit 21 determines the risk of a landslide to the house 8 by combining information sent from the sensor 34 that monitors signs of a landslide in the surrounding area.

Note that the disaster-related information also includes information about the risk of landslides, so by detecting the risk using the disaster-related information and the flood sensor 31, the probability of predicting landslides can be further increased. . Furthermore, the risk of a landslide to a house may be determined by combining the disaster-related information, the flood sensor 31, and the sensor 34 that monitors signs of a landslide.

In the example shown in FIG. 5, a flood sensor 31 and a sensor 34 for monitoring signs of a landslide are installed around the house 8. The sensor 34 that monitors signs of a landslide is a sensor such as an ultrasonic sensor or a Doppler sensor that monitors the movement of objects (trees, buildings, etc. standing on soil that may cause a landslide). It may be a device that detects signs of a landslide, or it may be a device that detects a landslide by monitoring the sounds and vibrations when a landslide occurs, such as a sound sensor or seismic sensor. Good too. In this way, the sensor 34 for monitoring signs of a landslide may be any known sensor.

Note that when rain or water accumulates around the house 8 due to heavy rain or the like, a detection signal is sent from the flood sensor 31 to the calculation unit 21. The calculation unit 21 that has received the detection signal can determine that the amount of moisture in the soil in the area around the house 8 has increased, so the output unit 22 outputs a message indicating that there is a risk of landslide. control. Furthermore, when a detection signal from the sensor 34 that monitors signs of a landslide is sent to the calculation unit 21, the calculation unit 21 detects that the risk of a landslide has increased in the area surrounding the house 8, or that the risk of a landslide has actually increased. It may be determined that a landslide has occurred, and the output unit 22 may output a message to that effect.

Although the present invention has been described above using the embodiments as examples, the present invention is not limited to the above embodiments, and can be modified in various ways. There are no restrictions on where various sensors can be installed; for example, sensors that monitor the status of the electrical system to detect the risk of fire to a house can be installed in the wiring path instead of inside the distribution board. It is. Furthermore, the type and number of disaster-related event sensors are not limited, and any event may occur as long as it occurs in a house, and by providing multiple disaster-related event sensors, The accuracy of detecting the risk of disaster may be improved.
