Description

The present invention relates to a disaster prevention system and a disaster prevention method using structural health monitoring technology.

Since the Great East Japan Earthquake, various measures for evacuation of residents and human and material support in the event of disasters such as earthquakes and tsunamis have been studied.
Elementary and junior high school buildings, public halls, halls, etc. that are diverted as shelters in the event of a disaster meet prescribed earthquake resistance standards based on the Building Standards Act, etc., and can protect the lives and bodies of evacuees without collapsing due to major earthquakes, etc. It is required to be a safe building.

  However, even if the building satisfies the specified earthquake resistance standards, the risk of collapse due to a subsequent aftershock is higher than before if a large damage caused by the earthquake causes structural damage. If a large number of evacuees are housed in a building with such a high risk of collapse, many lives are at risk.

  Conventionally, as shown in Patent Document 1, a technique for diagnosing the structural performance of a building based on acceleration data of a plurality of seismographs (acceleration sensors) and reporting the diagnosis result to a central disaster prevention center has been proposed. Yes. The structural health monitoring technique is described in more detail in Non-Patent Document 1.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic overall configuration diagram of a disaster prevention system according to an embodiment of the present invention. In this embodiment, the first elementary school S1, the second elementary school S2, and the third elementary school S3 are designated in advance as refuge candidates for residents at the time of disaster such as an earthquake. Implemented by City Hall G, which plays a role.

  As shown in FIG. 1, shelter computers (hereinafter simply referred to as “computer 130S”) are installed in the first to third elementary schools S1 to S3 as shelter candidates. In addition, a disaster prevention center computer (hereinafter simply referred to as “computer 130G”) is installed in the city hall G as a disaster prevention center. A computer 130H is also installed in the hospital H, which is in business in cooperation with the city hall G when a disaster occurs. Computers 130M and 130N are also installed in a human resource procurement center M that dispatches predetermined human resources to an evacuation center and a material procurement center N that conveys materials in the event of a disaster. Here, the human resource procurement center M and the material procurement center N are collectively referred to as a resource procurement center R.

The human resources procurement center M is a facility or institution for procuring human resources to accept residents in evacuation shelters, accept various supplies, set up evacuation facilities, take care of refugees' personal life, nursing, care, etc. This includes municipal offices, police stations, self-defense forces, and volunteer groups. The human resource procurement center M only needs to have a function of procuring and dispatching a required number of human resources according to the human support instruction received from the computer 130G of the city hall G. Absent.
The material procurement center N is a facility that stores various materials such as beverages / food, bedding, daily necessities, medicines, televisions, radios, lighting equipment, air conditioning equipment, and fuel to be transported to an evacuation center. Materials to be stored may include emergency generators, chargers, communication facilities, and the like.

  The computers 130 </ b> S, 130 </ b> G, 130 </ b> H, 130 </ b> M, and 130 </ b> N are connected to each other by a wired or wireless network 200 and configured to be able to transmit and receive information through the network 200. The network 200 includes a robust local area network (LAN) that can withstand a large-scale earthquake.

  In the present embodiment, a plurality of buildings are configured so that structural performance can be diagnosed by structural health monitoring technology. Specifically, at least a structural health monitoring system is introduced into the first elementary school S1, the second elementary school S2, and the third elementary school S3 designated in advance as shelters. A structural health monitoring system may be introduced into the city hall G, hospital H, human resources procurement center M, and material procurement center N.

  Hereinafter, the first elementary school S1 in FIG. 1 will be described as an example. FIG. 2 is a configuration diagram of the structural health monitoring system of the first elementary school S1. The second elementary school S2 and the third elementary school S3 have the same configuration.

  As shown in FIG. 2, acceleration sensors 101 to 104 are installed on each floor and ground of the first elementary school S1. The acceleration sensor needs to be installed at least on the lower floor (first floor), the higher floor (top floor), and the ground of the building, and for a high-rise building or the like, it is also necessary to install it on the middle floor. The acceleration sensors 101 to 104 measure earthquakes (including insensitive earthquakes that cannot be felt by humans), microtremors from vibration sources from cities, and the like.

  As the acceleration sensors 101 to 104, high-sensitivity sensors of 0.1 gal or less that can detect insensitive earthquakes are used. As the acceleration sensors 101 to 104, MEMS (Micro Electro Mechanical Systems) type acceleration sensors are used. By using the MEMS type acceleration sensor instead of the conventional servo type, the size can be reduced and the cost can be reduced.

  The acceleration data output from the acceleration sensor is input to the recording device 120 via the hub 110a. The recording device 120 stores the acceleration data of the synchronized acceleration sensors 101 to 104.

A computer 130 </ b> S is connected to the recording device 120, and the computer 130 </ b> S is connected to the network 200 via the router 140.
Although not shown, it is desirable to separately provide an uninterruptible power supply to supply power to the recording device 120, the computer 130S, etc. even in the event of a disaster.

  In addition, the robot 10S is installed in the first elementary school S1 that is installed in the evacuation center in advance. The robot 10S is a security robot, a cleaning robot, a communication robot, a multipurpose robot, an entertainment robot, or the like. The robot 10S is connected to the network 200 via the wireless repeater 150 and the hub 110b. A robot 10S is also installed in the second elementary school S2 and the third elementary school S3.

FIG. 3 is a diagram showing an example of the configuration of the computer 130S.
The computer 130S is configured by hardware and software of a computer system, and includes an input / output interface 131, an input unit 132 such as a keyboard and a mouse, an output unit 133 such as a display and a printer, an arithmetic processing unit 134S including a CPU, A storage unit 135 that stores various data and programs, and a communication control unit 136 for transmitting and receiving data and commands to and from the network 200 are provided.

  The basic configuration of the computer 130G of the city hall G, the computers 130S of the other elementary schools S2 and S3, and the other computers 130H, 130M, and 130N is the same as that shown in FIG.

Here, a function of the arithmetic processing unit 134S of the computer 130S is shown in a block diagram as shown in FIG.
In FIG. 4, the analysis unit 134 a calculates the maximum acceleration and the maximum interlayer deformation angle (the twice integrated value of the acceleration detection value) based on the acceleration data of each floor received from the recording device 120, and the natural frequency and mode ( The decrease in rigidity is calculated from the change in the amplitude shape when vibrating at the natural frequency. The diagnosis unit 134b outputs a structural performance diagnosis result of the first elementary school S1 based on a predetermined diagnosis program. For example, the diagnosis unit 134b outputs a diagnosis result in which the first elementary school S1 is a safe building when the maximum interlayer deformation angle or the decrease in rigidity is within a predetermined standard, and the first elementary school S1 when the predetermined standard is exceeded. Outputs the diagnosis result that is a dangerous building.
When the structural health monitoring system is introduced into the city hall G, the hospital H, the human resources procurement center M, and the material procurement center N, the arithmetic processing units of the respective computers 130G, 130H, 130M, and 130N have the same function.

The structural performance diagnosis results of the first to third elementary schools S1 to S3 are displayed on the output unit 133 such as a display in FIG. 3 and transmitted from the communication control unit 136 to the computer 130G of the city hall G via the network 200. The
That is, in the disaster prevention system according to this embodiment, the computer 130G of the city hall G can sequentially grasp the structural performance diagnosis results of the first to third elementary schools S1 to S3.

5-7 has shown the display screen 133a of the output part 133 of the computer 130S installed in 1st elementary school S1. FIG. 8 shows a display screen 133a of the computer 130S installed in the second elementary school S2, for example. The display information shown in FIGS. 5 to 8 is preferably transmitted to the computer 130G of the city hall G so that the same screen can be displayed in real time on the output unit of the computer 130G.
In addition, the computer 130S of each elementary school S1-S3 can be installed in each staff room, for example.

  FIG. 5 is a display screen 133a before the occurrence of the earthquake. The display screen 133a is provided with a seismic intensity display unit 133b that displays the current seismic intensity and the maximum seismic intensity (both estimated values) of each floor, and a diagnostic result display unit 133c that displays a diagnostic result of the structural performance of the school building. Before the occurrence of the earthquake, each of the display units 133b and 133c is blank.

  FIG. 6 is a display screen 133a during the occurrence of an earthquake. Due to the occurrence of the earthquake, the arithmetic processing unit 134S calculates the seismic intensity from the acceleration waveform measured by the acceleration sensors 101 to 103, and displays the current value and the maximum value of the seismic intensity of each floor on the seismic intensity display unit 133b. The earthquake occurrence time is displayed on the time display unit 133d, and an alarm indicating the occurrence of the earthquake is displayed on the alarm display unit 133e.

FIG. 7 shows the display screen 133a after the occurrence of the earthquake. As shown in FIG. 7, the diagnosis unit 134b in the arithmetic processing unit 134S of the computer 130S diagnoses the structural performance of the first elementary school S1, and displays the result on the diagnosis result display unit 133c.
In the example of FIG. 7, the first elementary school S1 is determined to be dangerous by the diagnosis unit 134b, and this is displayed on the diagnosis result display unit 133c.

During this time, the structural performance diagnosis is also performed in another elementary school, for example, the second elementary school S2.
FIG. 8 shows a display screen 133a in the second elementary school S2. If the ground is more stable in the second elementary school S2 than in the first elementary school S1, or if there is no risk of the school building collapsing because of sufficient seismic construction, the second elementary school S2 Is diagnosed as “safe”, and the fact is displayed on the diagnosis result display section 133c.

In addition, when the structural health monitoring system is introduced in the city hall G, the hospital H, the human resources procurement center M, and the material procurement center N, not only the structural performance diagnosis results of the first to third elementary schools S1 to S3, These structural performance diagnosis results may also be transmitted to the computer 130G of the city hall G.
The structural performance diagnosis is not necessarily executed by the computers 130S, 130G, 130H, 130M, and 130N of each building. For example, the acceleration data of the acceleration sensors 101 to 104 may be transmitted to the computer 130G of the city hall G, and the structural performance of each building may be diagnosed by the computer 130G of the city hall G.

  FIG. 9 is a block diagram illustrating functions of the arithmetic processing unit 134G in the computer 130G of the city hall G. The arithmetic processing unit 134G selects a shelter selection unit 134c that selects a safe building as a shelter based on the structural performance diagnosis results of a plurality of buildings, and selects a shelter for a building that has not been selected as a shelter. It functions as an evacuation instructing unit 134d that transmits information on the buildings that have been selected and instructs the evacuees of the buildings not selected as evacuation centers to evacuate to the buildings selected as evacuation centers.

  The refuge selection unit 134c selects a safe building as a refuge from the first to third elementary schools S1 to S3 designated in advance as refuges. As a result, a building that has been prepared in advance as an evacuation site is selected as an evacuation site, so that it is possible to avoid confusion or the like with respect to the acceptance of evacuees. However, limiting the selection target to buildings designated as evacuation shelters will limit the choices, so that the evacuation shelter selection unit 134c is operated by the city hall G, hospital H, human resources procurement center M, and material procurement center N. Etc. may be selectable as shelters.

The arithmetic processing unit 134G functions as a support determining unit 134g that determines the amount of resources to be sent to the building selected as the refuge. The support determination unit 134g determines the amount of resources to the building based on the estimated number of evacuees of the building, taking into account the number of evacuees evacuating from the building not selected as the evacuation site. The support determination unit 134g includes a personnel dispatch determination unit 134e and a material transport determination unit 134f.
The arithmetic processing unit 134G functions as a robot operation unit 134h that remotely controls the robot 10S.

Hereinafter, the function of the arithmetic processing unit 134G will be described in detail.
The shelter selection unit 134c selects a safe building as a shelter based on the structural performance diagnosis results of the first to third elementary schools S1 to S3. The refuge selecting unit 134c selects, for example, the second elementary school S2 and the third elementary school S3 diagnosed as safe without selecting the first elementary school S1 diagnosed as dangerous.

  The evacuation instruction unit 134d issues an instruction to evacuate the first elementary school S1 refugee who has not been selected as a refuge to the building selected as the refuge. Specifically, an evacuation instruction signal 160 for instructing evacuation is transmitted from the communication control unit 136 to the computer 130S of the first elementary school S1 via the network 200.

  If there are a plurality of buildings selected as the evacuation shelter, the evacuation instruction unit 134d transmits two or more pieces of information on the buildings selected as the evacuation shelter to the buildings not selected as the evacuation shelter. Instruct the evacuees of buildings that were not selected to evacuate to the buildings selected as shelters. Therefore, here, the evacuation instruction unit 134d includes the information of the second elementary school S2 and the third elementary school S3 in the evacuation instruction signal 160 and transmits the information to the computer 130S of the first elementary school S1, and then sends the second elementary school S2 and the third elementary school S3. Instruct them to evacuate and evacuate.

The evacuation instruction unit 134d determines the allocation of refugees to the first elementary school S1 to new evacuation destinations (second elementary school S2, third elementary school S3) in consideration of various conditions. Originally, the approximate number (accommodation number) of each elementary school S1 to S3, which was originally regarded as a refuge candidate, is determined in advance. Therefore, the evacuation instruction unit 134d determines the allocation in consideration of the capacity of the second elementary school S2, the third elementary school S3, the size of the second elementary school S2, the third elementary school S3, the distance from the first elementary school S1, and the like. .
Even when the shelter selection unit 134c selects a plurality of shelters, depending on the distances of the plurality of shelters (when not within a predetermined distance), the evacuation instruction unit 134d does not instruct distributed evacuation. It may be set.

  Upon receiving the evacuation instruction signal 160, the first elementary school S1 notifies the residents of the evacuation to the second elementary school S2 or the third elementary school S3 using the notification system (broadcasting system) of the first elementary school S1. It is also desirable to notify the residents of evacuation using appropriate transmission means (local television, FM broadcast, street broadcast, public information vehicle, telephone, etc.). At this time, the residents are notified of each evacuation destination based on the allocation of the refugees included in the evacuation instruction signal 160.

FIG. 10 is a conceptual diagram for explaining an evacuation situation.
In FIG. 10, P ₁ , P _1a , P _1a , P ₂ , and P ₃ are the numbers of a plurality of resident groups, respectively, and the number P ₁ that was originally scheduled to evacuate to the first elementary school S ₁ is the second elementary school. S2 is _{P 1a, P 1b} third Elementary S3, and will be evacuated allocated respectively. In this case, the assumed number of evacuees in the elementary schools S2 and S3 is P ₂ + P _1a and P ₃ + P _1b , respectively. The assumed increase ratio of evacuees (the increase ratio relative to the original number of evacuees) is (P ₂ + P _1a ) / P ₂ , (P ₃ + P _1b ) / P ₃ , respectively.

If the numbers P ₁ , P ₂ , and P ₃ are almost equal and P _1a : P _1b ≈3: 2, the assumed increase rate of evacuees in the second elementary school S2 is 1.6 times. The assumed increase ratio of evacuees at 3 elementary school S3 is 1.4 times.

  Assuming that the amount of human and material support for evacuees is proportional to the number of evacuees, the number of human resources and the amount of goods that should be sent to each elementary school S2, S3 to support evacuees is (Estimated number of evacuees) can be determined. From this, the human resource dispatch determination unit 134e and the material transport determination unit 134f obtain the assumed increase ratio (the number of assumed refugees) from the evacuation instruction signal 160 of the evacuation instruction unit 134d, and respectively send it to the second elementary school S2 and the third elementary school S3. Recognize how much human resources and supplies should be sent.

The personnel dispatch determining unit 134e in FIG. 9 determines the number of personnel to be dispatched to each of the elementary schools S2 and S3, and transmits it as a resource support command (personal support command) to the computer 130M of the personnel procurement center M in FIG. The same information is transmitted to the computers 130S of the elementary schools S2 and S3 on the side of accepting the dispatched personnel.
9 determines the amount of goods to be distributed to each elementary school S2 and S3, and transmits it as a resource support command (physical support command) to the computer 130N of the material procurement center N in FIG. At the same time, the same information is transmitted to the computers 130S of the elementary schools S2 and S3 on the side of accepting the conveyed goods. Here, it is assumed that the human support instruction and the physical support instruction include the scheduled arrival date of human resources and supplies to each elementary school.

The computer 130M of the human resources procurement center M procures a necessary number of human resources of a predetermined mission and type according to the received human support instruction, and dispatches them to each elementary school at the scheduled date and time. Further, the computer 130N of the material procurement center N procures a predetermined number of necessary materials in accordance with the received physical support instruction, and transports them to each elementary school on the scheduled date and time.
As described above, since the elementary school S2 and S3 have already received the human support instruction and the physical support instruction from the computer 130G of the city hall G, the acceptance system of human resources and supplies is already in place.

  As described above, even if evacuation to an elementary school diagnosed as dangerous is impossible among multiple elementary schools that are evacuation shelter candidates, refugees can be assigned to other safe elementary schools. On the other hand, an appropriate and sufficient amount and type of human resources and supplies can be sent as resources.

  In addition, it is dangerous for residents to act in the first elementary school S1 diagnosed as dangerous (not selected as a refuge). Therefore, in this embodiment, the robot operation unit 134h remotely operates the robot 10S of the first elementary school S1 from the communication control unit 136 via the network 200 and the wireless repeater 150, and performs the work in the first elementary school S1. To do.

FIG. 11 is a functional block diagram of the robot 10S of the first elementary school S1. The robot 10S of the second elementary school S2 and the third elementary school S3 is assumed to have the same configuration.
As shown in FIG. 11, the robot 10S has a patrol sensor 208 for patroling the first elementary school S1. The traveling sensor 208 includes a distance sensor, an angle sensor, and the like.

  Detection data of the traveling sensor 208 is transmitted to the drive control unit 210 via the input / output interface 202. The drive control unit 210 includes a central processing unit (CPU), and generates a control command for the drive mechanism 209 based on the detection data of the patrol sensor 208. The drive mechanism 209 includes a motor, wheels, walking means, and the like, and moves the robot 10S according to this control command.

  Further, the robot 10S includes an imaging unit 201 that can capture a still image or a moving image. The imaging unit 201 includes a camera and the like. The still image or moving image captured by the imaging unit 201 is input to the recording unit 203 via the input / output interface 202. The recording unit 203 includes a ROM, a RAM, and the like. The arithmetic processing unit 204 causes the wireless transmission / reception unit 205 to transmit the still image or moving image input to the recording unit 203 to the computer 130G of the city hall G. The arithmetic processing unit 204 is configured including a central processing unit (CPU), and comprehensively controls all functions and operations of the robot 10S.

The robot 10S also includes an evacuee detection unit 206 that includes a microphone, an infrared sensor, and the like and detects an evacuee, and an evacuee response unit 207 that includes a speaker and a display and responds to the evacuee. .
Thereby, a new evacuation destination is transmitted from the evacuee response unit 207 to the evacuees who evacuate to the first elementary school S1 by remote control by the robot operation unit 134h, or evacuees who remain in the first elementary school S1. The imaging unit 201 and the refugee detection unit 206 can detect and call for evacuation, or the driving mechanism 209 can patrol the first elementary school S1. Therefore, since it is not necessary for the residents to stay in the first elementary school S1 diagnosed as dangerous or for the residents to work in the first elementary school S1, the safety of the residents can be ensured.

As described above, according to the present embodiment, from the result of the structural performance diagnosis of the building by the structural health monitoring technology, to a new evacuation destination where the earthquake-proof performance is sufficiently secured for the evacuees of the building diagnosed as dangerous. Because instructions are given promptly to evacuate, the safety of residents can be ensured. At this time, if there are multiple buildings selected as evacuation centers, there will be a flood of residents in one evacuation area in order to issue instructions to evacuate to two or more new evacuation destinations. And can evacuate residents appropriately.
In addition, the disaster prevention center (city hall G) can centrally manage the risks associated with the collapse of the evacuation center, so that not only can safe and secure evacuation be provided to evacuees, but also the command at the disaster prevention center. It is also possible to strengthen the system (improve command capability).

  The structural performance diagnosis of the building based on the acceleration data of the acceleration sensor can be executed at any time in real time. Therefore, even if a resident evacuates to an elementary school, if the safety diagnosis result of the elementary school is changed from “safe” to “dangerous” due to a subsequent aftershock, the computer 130G of the city hall G will newly evacuate. The destination can be determined, and the evacuation site selection information can be transmitted to the computer 130S of the elementary school to prompt evacuation again. At the same time, the computer 130G newly generates a human / physical support instruction and transmits it to each procurement center M, N, etc., so that appropriate human / physical support for a new evacuation destination can be performed.

  In addition, according to the structural health monitoring technology, it is possible to determine the appropriate timing of earthquake-proofing work and repair work by diagnosing the structural performance of the building over time. Therefore, according to this embodiment, it is possible to manage the necessity of earthquake-proof construction and repair work of the first to third elementary schools S1 to S3 at the disaster prevention center (city hall G).

Needless to say, the number and types of facilities as evacuation shelters are not limited to the above embodiment, and different buildings (for example, gymnasiums and classrooms) in the same facility (for example, elementary school) are each evacuation shelter candidates. The present invention may be applied as follows.
According to an embodiment of the present invention, there is a disaster prevention system in which a plurality of buildings for diagnosing structural performance using a structural health monitoring technology are connected via a network, and transmits and receives information through the network. The evacuation center selection section selects safe buildings as evacuation shelters from the structural performance diagnosis results, and sends information on the buildings selected as evacuation centers to buildings that were not selected as evacuation shelters. There is provided a disaster prevention system including an evacuation instruction unit for instructing an evacuee of a building not selected to evacuate to a building selected as an evacuation site.
The disaster prevention system may further include a disaster prevention center computer installed in the disaster prevention center and connected to a network, and the disaster prevention center computer may function as an evacuation center selection unit and an evacuation instruction unit.
The above-described shelter selection unit may select a safe building as a shelter from among a plurality of buildings previously designated as shelters.
The disaster prevention system further comprises a shelter computer installed in a building designated in advance as a shelter and connected to the network, and the shelter computer uses the structural health monitoring technology to determine the maximum interlayer deformation angle or natural frequency and Calculates the decrease in rigidity required from the mode change, and outputs the diagnosis result that the building is a safe structure to the disaster prevention center computer when the maximum interlayer deformation angle or the decrease in rigidity is within the specified standard. Good.
If there are multiple buildings selected as evacuation shelters, the above evacuation instruction section sends two or more pieces of information about the buildings selected as evacuations to buildings that were not selected as evacuation shelters. It may be instructed to evacuate the evacuees of the buildings that are not selected as places to the buildings selected as the refuges.
The disaster prevention system further includes a support determination unit that determines the amount of resources to be sent to the building selected as the evacuation site, and the support determination unit determines the number of refugees evacuating from the building not selected as the evacuation site. The amount of resources for the building may be determined based on the estimated number of evacuees in the building taking into account the above.
The disaster prevention system further includes a robot installed in a plurality of buildings designated as shelters in advance, and the robot is operated remotely when the building in which the robot is installed is not selected as a shelter. It should be possible.
