Description

  The present invention is applicable to residential facilities such as apartment buildings, commercial facilities such as shopping centers, accommodation facilities such as hotels, or industrial facilities such as factories, and detects toxic gas and notifies safe evacuation routes. The present invention relates to toxic gas detection and evacuation guidance systems.

  Conventionally, in order to safely and quickly guide evacuation of disaster victims when a disaster occurs, guide lights are installed in residential facilities, commercial facilities, accommodation facilities, industrial facilities, and the like.

  However, in recent years, there have been many cases of unexpected toxic gas generation in such facilities.

When toxic gas is generated, if there is no evacuation by an accurate route, there is a risk that a toxic gas will be sucked during evacuation and a secondary disaster will occur. For example, hydrogen sulfide (hereinafter H ₂ S), which is frequently reported due to chemical accidents and suicide, has a specific gravity of 1.19, which is heavier than air. On the other hand, H ₂ S is sucked, which is dangerous. Also, carbon monoxide (hereinafter referred to as CO) generated by incomplete combustion of gas appliances has a specific gravity of 0.97, which is slightly lighter than air. There is a possibility that. An invention for notifying the evacuation posture has been proposed by paying attention to the specific gravity of such toxic gas (Patent Document 1).

  Moreover, when a disaster occurs in a building, an invention has been proposed in which an evacuation route is set according to the location and scale of the disaster and a notification is made (Patent Document 2).

JP-A-6-241874 JP 2000-113357 A

  However, the invention disclosed in Patent Document 1 merely notifies the evacuation posture in accordance with the detected type of toxic gas, and is not configured to notify the evacuation route.

  The invention disclosed in Patent Document 2 divides a building into predetermined three-dimensional blocks, determines the current state of a disaster, predicts the time transition thereof, and searches for a safe evacuation route.

  However, the invention of Patent Document 2 is described in detail when a fire occurs, but does not mention a method for calculating an evacuation route when a toxic gas is generated.

  The present invention has been made in view of the above-described problems, and by inhaling toxic gas during evacuation, it is possible to evacuate residents and facility users safely without inducing a secondary disaster. An object is to provide a poison gas detection and evacuation guidance system.

  In the toxic gas detection and evacuation guidance system according to the present invention, a plurality of toxic gas detection means provided in each room or passage of a building having a plurality of levels detect the concentration, type and location of the generated toxic gas. The evacuation route is determined based on the detected concentration, type and location of the toxic gas, and the determined evacuation route is notified visually or audibly so that the toxic gas generated during the evacuation can be detected. It informs of a safe evacuation route that does not suck.

  That is, the toxic gas detection and evacuation guidance system according to the present invention is installed in each room or passage of a multi-level building, and detects the concentration of toxic gas, the type of toxic gas, and the location where the toxic gas is generated. A plurality of toxic gas detection means for outputting, a monitoring means for monitoring the outputs of the plurality of toxic gas detection means, and based on the monitoring result of the monitoring means, from the type of toxic gas and the generation location, An evacuation route determination means for calculating an evacuation route from each room or passage to the outside of the building (hereinafter simply referred to as the outside), and the evacuation route determined by the evacuation route determination means to each room or passage An informing means for informing visibly or audibly, an information transmitting means for transmitting information by connecting the toxic gas detecting means, the monitoring means, and the informing means. And said that there were pictures.

  According to the toxic gas detection and evacuation guidance system of the present invention, the toxic gas concentration, type and location of occurrence are detected by the toxic gas detection means installed in each room (hereinafter referred to as each door) or passage on each floor. The detected toxic gas concentration, type and location are transmitted to the monitoring means by the information transmission means, and the monitoring means sends the evacuation route to the evacuation route determination means based on the concentration, type and location of the toxic gas. The evacuation route determination means determines the evacuation route based on the type and location of the toxic gas, and the determined evacuation route is sent to the notification means provided in each door or passage by the information transmission means. The information is sent and notified to each door or passage visually or audibly by the notification means. Therefore, an appropriate evacuation route is transmitted to residents and users in each building or passage of the building, and it is possible to evacuate safely to the outside.

  Further, in the toxic gas detection and evacuation guidance system according to the present invention, the building is provided with an emergency stairway leading to the outside of the building on each floor, and the evacuation route determination means is configured to detect the toxic gas detected. When the specific gravity determined uniquely from the type is smaller than that of air and the concentration of the toxic gas is equal to or higher than a predetermined value, the floor where the toxic gas is detected and the floor below the floor where the toxic gas is detected For the above, the route for evacuating from each floor to the lower floor is determined as the evacuation route, and the emergency stairs from each floor to the upper floor than the floor where the toxic gas is detected. The evacuation route is determined as the evacuation route, and when the specific gravity uniquely determined from the type of the toxic gas is greater than that of air and the concentration of the toxic gas is a predetermined value or more, For a floor where gas is detected, a route to evacuate is determined as the evacuation route using the emergency stairs above the floor where the toxic gas is detected, and from the floor where the toxic gas is detected For the upper floors, a route for evacuating from each floor using the emergency stairs is determined as the evacuation route, and for floors lower than the floor where the toxic gas is detected, from each floor It is desirable that the route for evacuating toward the lower floor is determined as the evacuation route.

  According to the toxic gas detection and evacuation guidance system according to the present invention configured as described above, when the specific gravity of the detected toxic gas is smaller than air and the concentration of the toxic gas is equal to or higher than a predetermined value, For lower floors, including floors where poisonous gas has been generated, a route to evacuate to the lower floors is instructed. For floors higher than toxic gas, evacuate from the emergency stairs on each floor. The route to be directed is indicated.

  In addition, when the specific gravity of the detected toxic gas is greater than that of air and the concentration of the toxic gas is equal to or higher than a predetermined value, the floor where the toxic gas is generated is temporarily raised from the floor to the upper floor. The route to evacuate using the emergency stairs on the upper floor is instructed, and for the upper floors above the floor where toxic gas is generated, the route to evacuate from the emergency stairs on each floor is directed, and the floor where toxic gas is generated For the lower floor, a route to evacuate toward the lower floor is instructed.

  Therefore, when toxic gas with low specific gravity is generated, the generated gas spreads upward, so a downward evacuation route that is opposite to the direction in which toxic gas is spread is set on the floor where toxic gas is generated. By notifying the evacuation route, it is possible to prevent the occurrence of a secondary disaster that sucks toxic gas during evacuation.

  In addition, when toxic gas with a large specific gravity is generated, the generated gas spreads to the floor. By setting an evacuation route to be notified and informing the evacuation route, it is possible to prevent the occurrence of a secondary disaster that sucks in toxic gas during evacuation.

Furthermore, in the toxic gas detection and evacuation guidance system according to the present invention, it is desirable that the toxic gas detected by the toxic gas detection means is at least one of H ₂ S and CO.

According to the toxic gas detection and evacuation guidance system according to the present invention configured as described above, when H ₂ S and CO are generated, an evacuation route based on their specific gravity can be calculated and notified. . Therefore, a safe evacuation route can be instructed to a resident or user of a building even when H ₂ S or CO has frequently been reported recently.

  In the toxic gas detection and evacuation guidance system according to the present invention, it is preferable that the information transmission means transmits at least information detected by the toxic gas detection means through a power line that supplies power to each room or passage. .

  According to the toxic gas detection and evacuation guidance system according to the present invention configured as described above, the concentration, type, and location of the toxic gas detected by the toxic gas detection means through the power supply power line already installed in the building, Can be transmitted to the monitoring means, whereby the monitoring means can instruct the evacuation route determination means to determine the evacuation route based on the concentration, type and location of occurrence of the toxic gas. The evacuation route determined by the determination means can be notified. Therefore, it is possible to reduce the amount of electric wires used for installing the toxic gas detection and evacuation guidance system, and hence the time required for the installation work can be shortened, so that the installation cost can be reduced.

  According to the toxic gas detection and evacuation guidance system according to the present invention, when a toxic gas is generated, the residents and users of the building can be evacuated safely without inducing a secondary disaster that sucks the generated toxic gas. Can do.

In addition, as shown in FIG. 2B, residential areas are arranged on the third floor with the passage 910 interposed therebetween. The elevator 900 or the stairs 800 is used to go to the upper and lower floors. Moreover, the 1st emergency staircase 810 and the 2nd emergency staircase 820 are installed in the both ends of each floor. It is assumed that this structure is the same on floors other than the third floor. In addition, as shown in FIG. 2C, a first stairway 840 leading to the outside is provided in the first floor portion of the first emergency staircase 810, and the first floor portion of the second emergency staircase 820 leads to the outside. A second stairway 850 is provided, and a third stairway 830 leading to the outside is provided in the first floor portion of the staircase 800.

  The toxic gas detection and evacuation guidance system 1 according to the present embodiment detects the concentration, type, and location of toxic gas generated in each house, and is provided with a unique ID number that uniquely identifies the installation location. Means 100, monitoring means 300 for monitoring information on the concentration, type and location of the toxic gas detected by the toxic gas detection means 100 of each house, and the concentration and location of the toxic gas monitored by the monitoring means 300. Based on the evacuation route determination means 400 for determining the evacuation route of each door (hereinafter referred to as evacuation route information), the notification means 500 for visually or audibly informing the determined evacuation route information to each door, and Information transmission for transmitting poisonous gas detection means 100, the monitoring means 300, and the notification means 500 to convey the type, concentration, location of toxic gas, and evacuation route information And it includes a stage 200.

Toxic gas detection means 100, specifically, the _{H 2} S detection sensor 110 for detecting the _{H 2} S, and CO detection sensor 120 for detecting the CO, toxic gas detected by the _{H 2} S detection sensor 110 and the CO sensor 120 And a sensor information collecting unit 130 that collects the concentration of the sensor.

Specifically, the information transmission means 200 is installed in each house, and the H ₂ S concentration collected by the sensor information collection unit 130, the CO concentration, and the ID number of the toxic gas detection means 100 (hereinafter collectively referred to as “collection”). Evacuation modulated to superimpose on the commercial AC voltage signal (hereinafter simply referred to as AC voltage signal) and further transmitted from the evacuation route determination means 400 while being superimposed on the AC voltage signal. A first information modulation / demodulation unit 210 that demodulates path information, a first power outlet 220 that supplies an AC voltage to each house, and an administrator room 610 shown in FIG. The second power outlet 230 to be supplied and the evacuation route information calculated by the evacuation route determination means 400 are modulated so as to be superimposed on the AC voltage signal. A power line that connects the second information modulation / demodulation unit 240 that demodulates the toxic gas detection information transmitted by being superimposed on the pressure signal, the first power outlet 220 and the second power outlet 230, and supplies an AC voltage signal to each house. 225. Note that operating power is supplied from the first power outlet 220 to the toxic gas detection means 100, the first information modulation / demodulation unit 210, and the notification means 500, and from the second power outlet 230, the second information modulation is performed. Operating power is supplied to the demodulation unit 240, the monitoring unit 300, and the evacuation route determination unit 400.

  Specifically, the evacuation route determination means 400 includes an evacuation route database 410 that stores preset evacuation route information for each house based on the structure of the apartment house 600 and guidance information that expresses the evacuation route information in text or voice. Based on the toxic gas detection information and the evacuation route information and guidance information stored in the evacuation route database 410, the evacuation route determination unit 420 for determining the evacuation route information of each house is determined based on the instruction from the monitoring unit 300. And an evacuation route presentation unit 430 for presenting evacuation route information.

  More specifically, the notification unit 500 notifies the evacuation route information determined by the evacuation route determination unit 400 by voice, and the voice output unit 510 including a speaker and the evacuation route information determined by the evacuation route determination unit 400 by screen information. And an evacuation route presentation unit 520 composed of a display device.

  Here, the toxic gas detection means 100 and the notification means 500 are installed in each house of the apartment house 600, and the monitoring means 300 and the evacuation route determination means 400 are installed in the manager room 610.

Various types of sensors for detecting H ₂ S and CO have been devised. For example, a semiconductor sensor that detects changes in resistance when a metal oxide semiconductor comes into contact with these gases as a gas concentration, or gas is electrolyzed on an electrode held at a constant potential. A constant potential electrolytic sensor that detects a current generated in the gas as a gas concentration. Any of these sensors may be used as the H ₂ S detection sensor 110 and the CO detection sensor 120.

Since the specific gravity of H ₂ S is greater than that of air, it is desirable to install the H ₂ S detection sensor 110 near the floor surface. Since the specific gravity of CO is slightly smaller than that of air, the CO detection sensor 120 is close to the ceiling. It is desirable to install. This is to ensure that a trace amount of toxic gas can be detected.

  Next, the operation of the toxic gas detection and evacuation guidance system 1 according to the present embodiment will be described with reference to the flowchart of FIG.

The concentration of each toxic gas is constantly measured by the H ₂ S detection sensor 110 and the CO detection sensor 120 installed in each house, and the result is transmitted to the sensor information collection unit 130 and stored in the memory of the sensor information collection unit 130. Remembered. Since the memory included in the sensor information collection unit 130 has a capacity limitation, when density information is stored a predetermined number of times, the density information stored first is deleted in order.

The monitoring means 300 sequentially calls the toxic gas detection means 100 installed in each house using the ID number assigned to each toxic gas detection means 100 (S1 in FIG. 4), and the called toxic gas detection means 100 is The first H ₂ S concentration stored in the sensor information collecting unit 130, the latest CO concentration, and the ID number of the called toxic gas detection means 100 are collected as first toxic gas detection information. The information is transmitted to the information modulation / demodulation unit 210 (S2 in FIG. 4).

  The first information modulation / demodulation unit 210 modulates the toxic gas detection information with a carrier frequency of about 100 kHz, and the modulated toxic gas detection information has a voltage of 100 or 200 V, a frequency of 50 or This is superimposed on the 60 Hz AC voltage signal (S3 in FIG. 4).

  The reason why the toxic gas detection information is modulated is to increase the discrimination between the 50 or 60 Hz AC voltage signal and the toxic gas detection information. Since the frequency that can be used for indoor power line carrier communication is defined by law, the carrier frequency of the modulated wave is set to a frequency within that range, for example, 100 kHz. However, the carrier frequency is not limited to this frequency, and an appropriate frequency is selected in light of design requirements.

  The alternating voltage signal on which the toxic gas detection information is superimposed is transmitted from the first power outlet 220 of each house to the second information modulation / demodulation unit 240 via the power line 225 and further via the second power outlet 230 ( S4 in FIG.

  The second information modulation / demodulation unit 240 demodulates the toxic gas detection information based on the AC voltage signal on which the toxic gas detection information is superimposed (S5 in FIG. 4). The demodulated toxic gas detection information is sent to the monitoring means 300 (S6 in FIG. 4).

The monitoring means 300 collects toxic gas detection information from each house (S7 in FIG. 4), and monitors toxic gas detection information collected from each house (S8, S10, S11 in FIG. 4). Here, if the concentration of the toxic gas exceeds a preset threshold value (concentration threshold value D1 of H ₂ S, concentration threshold value D2 of CO), it is determined that toxic gas is generated, An instruction for evacuation route determination is issued to the evacuation route determination unit 420. Moreover, when the confirmation of the toxic gas detection information of all the houses is completed, the process returns to S1 in FIG. 4 again to continue monitoring (S16 in FIG. 4).

  The evacuation route determination unit 420 evacuates the evacuation route that is stored in the evacuation route database 410 in advance when the toxic gas is generated in the room where the monitoring unit 300 determines that the toxic gas is generated. Read route. (S9, S12 in FIG. 4).

  In addition, since it is dangerous to operate the elevator 900 when toxic gas is generated, the elevator 900 is stopped at the nearest floor according to an instruction from the evacuation route determination unit 420, and after the passenger gets off, the door is closed and the operation is performed. Stop (S13 in FIG. 4).

Next, a procedure for calculating evacuation route information will be described. The evacuation route database 410 stores in advance evacuation route information when toxic gas is generated. FIG. 3 shows actually stored evacuation route information when H ₂ S occurs and evacuation route information when CO occurs. Actually, the evacuation route information for all the houses of the apartment house 600 is prepared, but since the amount is complicated and complicated, only a part thereof is illustrated. The vertical axis of FIG. 3 describes the room number of each house where toxic gas is generated, and the horizontal axis describes the evacuation route of each house.

  In FIG. 3, the notation “X ↓” is connected to X by going down to the first floor using any one of the staircase 800, the first emergency staircase 840, or the second emergency staircase 850 described in the portion of X. A route for evacuating to the outside from the first stairway 840, the second stairway 850, or the third stairway 830 is shown.

  The notation “Staircase ↑” goes up one level using the staircase 800 and goes down to the first floor using the first emergency staircase 810 or the second emergency staircase 820 on the first floor. A route for evacuating to the outside from the first stairway exit 840 connected to the staircase 810 or the second stairway exit 850 connected to the second emergency staircase 820 is shown.

  Furthermore, the notation “Z →” indicates a route for evacuating to the outside from any one of the first stairway 840, the second stairway 850, or the third stairway 830 described in the portion Z. Represents.

For example, in FIG. 3, a resident in room 302 710 goes up to the fourth floor using stairs 800 when H ₂ S occurs in room 301, and uses the first emergency stairs 810 on the fourth floor to go to the first floor. Evacuate to the outside from the first stairway exit 840, or go down to the first floor using the second emergency staircase 820 on the 4th floor and evacuate to the outside from the second stairway exit 850 (see FIG. 3 P). In addition, for example, it is shown that a resident in Room 203 (not shown in FIG. 2) descends to the first floor using the stairway 800 and evacuates to the outside from the third stairway 830 (Q in FIG. 3). .

  On the other hand, T in FIG. 3 shows that when CO is generated in room 301, the resident in room 302 710 descends to the first floor using stairs 800 and evacuates to the outside from the third stairs entrance 830. ing.

Thus, even in the same room 302, different evacuation routes are instructed depending on the type of generated toxic gas. That is, when H ₂ S is generated on the nth floor, which has a higher specific gravity than air, if the n-th floor resident evacuates to the lower floor using the stairs 800, the H ₂ S has a higher specific gravity and falls downward. There is a risk that a secondary disaster will occur by sucking H ₂ S in the middle of evacuation or at the evacuation destination. Therefore, after going up to the upper floor, the route to evacuate is instructed using the emergency stairs on the upper floor. When H ₂ S occurs on the top floor, the route to evacuate is instructed using the first emergency staircase 810 or the second emergency staircase 820 after going up to the rooftop.

  On the other hand, when CO is generated with a slightly lower specific gravity than air, if you evacuate through the upper floors, there is a risk that the CO that has risen may inhal the CO while evacuating to the upper floors or at the evacuation destination. The route to evacuate to the lower floor is instructed using the stairs 800, the first emergency stairs 810, or the second emergency stairs 820.

  For the residents on the bottom floor, the first emergency stairway exit is provided on the shortest route to shorten the evacuation time and to facilitate the evacuation of residents on the upper floors, regardless of the type of toxic gas generated. A route to evacuate to the outside is instructed from 840, second emergency stairway exit 850, or third staircase exit 830.

Hereinafter, the flow of processing for notifying the evacuation route will be described. For example, when H ₂ S occurs in room 302 710, the evacuation route determination unit 420 stores the portion R in FIG. 3 corresponding to “when H ₂ S occurs in room 302” from the evacuation route database 410. Is read (S9 in FIG. 4). The evacuation route determination unit 420 determines an evacuation route based on the read evacuation route (S14 in FIG. 4), and creates sound and screen information to be notified to each house (S17 in FIG. 4). The voice and the screen information are created using the evacuation route information of each house stored in the evacuation route database 410 in advance and the guidance information expressing the information in text or voice. The created audio and screen information is assigned the same ID number as the ID number assigned to the toxic gas detection means 100 installed in the room informing the information, and is modulated by the second information modulation / demodulation unit 240. After that, the first information modulation / demodulation unit 210 installed in the corresponding room is superimposed on the AC voltage signal (S18 in FIG. 4), passes through the second power outlet 230, the power line 225, and the first power outlet 220. (S19 in FIG. 4).

  In each house, the first information modulation / demodulation unit 210 demodulates the AC voltage signal on which the sound and the screen information are superimposed (S20 in FIG. 4), and confirms that the ID number corresponding to each house is given. The voice output unit 510 and the evacuation route presentation unit 520 provided in each door notify the evacuation route by voice or screen information (S21 in FIG. 4).

For example, when H ₂ S is generated in the room 301, the speaker constituting the audio output unit 510 in the room 302, “hydrogen sulfide gas is generated in the room 301. “Please evacuate on the 4th floor emergency staircase” is output, and the screen information shown in FIG. 6 is displayed on the display constituting the evacuation route presentation unit 520. Residents in room 302 710 evacuate according to these voice guidance and screen information.

  As described above, according to the toxic gas detection and evacuation guidance system of the present embodiment, the toxic gas generated based on the concentration of the toxic gas, the specific gravity determined uniquely from the type of the toxic gas, and the location where the toxic gas is generated. For each type, it is possible to determine an evacuation route that does not inhale toxic gas during evacuation and to notify this, so it is possible to prevent secondary disasters during evacuation and evacuate safely. be able to.

  The evacuation route is not limited to the route shown in this embodiment. That is, the toxic gas detection means 100 may be installed not only in each house of the apartment house 600 but also in the passage 910 and the stairs 800. In that case, the evacuation route information corresponding to FIG. 3 can be set in more detail. Compared to the present embodiment, a more detailed evacuation route can be set.

  Further, in this embodiment, the evacuation route information determined by the evacuation route determination unit 420 is transmitted to each door via the power line 225 in the information transmission means 200 and is notified by the notification means 500 of each door. When the Internet line is laid in the apartment house 600, the evacuation route information determined by the evacuation route determination unit 420 may be transmitted to the notification unit 500 through the Internet line and notified to each house. In this case, the evacuation route information is transmitted after appropriate encoding is performed according to the Internet line.

  Alternatively, for example, in a small apartment, after the manager in the manager room 610 confirms the evacuation route information determined by the evacuation route determination unit 420, information on the evacuation route is reported to each house through a telephone line. It may be.

In the present embodiment, the case has been described where the H 2 _S occurs, even if the CO is generated, is calculated similarly evacuation routes, notifying them.

Furthermore, even when toxic gas is simultaneously generated in a plurality of rooms, or when H ₂ S and CO are simultaneously generated, the configuration of this embodiment can be used. However, in such a case, there are enormous numbers of toxic gas generation patterns, and it is difficult to create evacuation route information corresponding to FIG. 3 in advance. Therefore, it corresponds as follows.

For example, when H ₂ S occurs in a plurality of rooms at the same time, the evacuation route determination unit 420 first refers to the evacuation route in FIG. 3 and assumes that H ₂ S has occurred individually in each room. Calculate multiple evacuation routes. Next, the evacuation route determination unit 420 compares the evacuation routes in the same room among the calculated evacuation routes, and when the evacuation routes match, the matched evacuation route is determined as the final of the room. A simple evacuation route should be used.

On the other hand, when the evacuation routes of the same room do not match, the evacuation route determination unit 420 compares the H ₂ S concentrations of the rooms collected by the monitoring means 300 and the room with the highest H ₂ S generation concentration. May be the final evacuation route for the room.

When H ₂ S and CO occur simultaneously in different rooms, first, the evacuation route determination unit 420 first determines the evacuation route of each room with respect to H ₂ S and the evacuation route of each room with respect to CO. Calculate each. Next, the evacuation route determination unit 420 compares the evacuation route for H ₂ S and the evacuation route for CO in the same room, and when the evacuation routes match, the matched evacuation route is determined as the final of the room. A simple evacuation route can be used.

On the other hand, if the evacuation route for H ₂ S in the same room and the evacuation route for CO do not match, the evacuation route determination unit 420 has the most influence on the body based on the H ₂ S concentration and the CO concentration in each room. A room where a large amount of toxic gas is generated and the type of the toxic gas may be specified, and the evacuation route for the room may be the final evacuation route of the room.

  Further, in this embodiment, when a telephone line is connected to the monitoring unit 300 installed in the manager's room 610 and the monitoring unit 300 issues an instruction for evacuation route determination to the evacuation route determination unit 400, the telephone line If you configure the system to send toxic gas detection information to the fire department or police station using, you can send toxic gas detection information to these institutions at the same time as the generation of toxic gas, Rapid relief activities by the fire department and police can be implemented.

  Further, in this embodiment, the present invention is applied to the apartment house 600 shown in FIG. 2, but as long as the evacuation route information corresponding to FIG. Needless to say, it is applicable.
