  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a view for explaining a schematic configuration of an earthquake information providing system 1 according to an embodiment of the present invention. The earthquake information providing system 1 according to the present invention is installed in a predetermined building C, predicts the influence of the earthquake on the building C, and is provided with speakers 110, signage monitors 120 installed at a plurality of places in the building C hall. An information transmission unit such as the personal computer group 130 transmits information on earthquakes to people in the building C.

  As a main configuration of the earthquake information providing system 1 according to the present invention, an information processing apparatus 70 communicably connected to the communication line N is used. The information processing apparatus 70 includes a communication unit that transmits and receives data via the communication line N, an arithmetic processing unit that performs arithmetic processing of data, a storage unit that stores data, and a data display unit that displays data. A widely spread personal computer can be used. Of course, an information processing apparatus 70 other than a personal computer may be used as appropriate.

  The information processing device 70 is connected to the communication network N, and is configured to be able to receive information from the earthquake information transmission server 60 that transmits various types of earthquake information. The earthquake information transmission server 60 is assumed to be an example related to the earthquake early warning provided by the Japan Meteorological Agency, but another one can be used.

  The basis of the earthquake information transmission server 60 when transmitting information will be described. When an earthquake occurs, the earthquake information transmission server 60 instantaneously calculates the position of the earthquake source and the size of the earthquake from the initial tremors (P waves) detected by seismographs installed at a plurality of locations, and this information is "earthquake occurrence information" , And transmits to the information processing apparatus 70 via the communication network N. Furthermore, several seconds after the occurrence of the earthquake, seismographs that detect the seismic waves increase with the spread of the seismic waves due to the earthquake, so it is possible to predict the location and size of the earthquake source with higher accuracy. Accordingly, the earthquake information transmission server 60 transmits this as “update information” to the information processing apparatus 70 via the communication network N several seconds after the occurrence of the earthquake.

  FIG. 2 is a diagram for explaining the concept of time series of information transmission by the earthquake information transmission server 60. In FIG. 2, the distance between the epicenter and the building C is shown as X instead of the epicenter. Moreover, in FIG. 2, M has shown the earthquake scale. In FIG. 2, the earthquake information transmission server 60 transmits (earthquake scale M, epicenter distance X) as "earthquake occurrence information", but in "update information" updated every 20 seconds, for example, (earthquake scale In M ', the epicenter distance X'), and "update information" updated every 20 seconds or less, it changes as (seismic scale M '', epicenter distance X ''), ....

  As shown in FIG. 1, the information processing apparatus 70 is communicably connected to information transmitting units such as speakers 110, signage monitors 120, and personal computer groups 130 installed at a plurality of places in the building C. The information processing apparatus 70 performs predetermined arithmetic processing based on the information received from the earthquake information transmission server 60 as described above, and based on this, the information transmission unit such as each speaker 110, signage monitor 120, personal computer group 130, etc. Send data to be sent to

  FIG. 3 is a view showing an example of an installation state of the information transmitting unit in the building C. As shown in FIG. It is assumed that the building C described in the present embodiment has two east west sections, and in some cases, different sections transmit different information in each section according to the degree of scattering in the room due to earthquakes. Let's do it. FIG. 3 is a diagram for bird's eye view of the first floor of the building C, and the section on the right side indicates the first floor east, and the section on the left side indicates the first floor west. It can be seen that the configuration shown in the bird's-eye view of FIG. 3 is mainly a fixture, and the number is small in the first floor east and large in the first floor west. As will be described later, the number of fixtures in each section is held as data, and is used for information transmission in each section.

  The speakers 110 shown in the bird's eye view transmit information on earthquakes to people in each section by uttering voice data provided in each section and transmitted from the information processing apparatus 70. In addition, the signage monitor 120 shown in the bird's-eye view shows information on earthquakes to persons in each section by displaying the display data provided in each section and transmitted from the information processing apparatus 70. In the personal computer group 130 used in each section, it is preferable that sound data and display data related to earthquakes be reproduced from the information processing apparatus 70 in a push type.

  In the present embodiment, the information transmission unit will be described using the speaker 110, the signage monitor 120, and the personal computer group 130 as an example, but other information transmission means may be used.

  The storage unit (not shown) of the information processing apparatus 70 stores a database 80 that describes various data used in the earthquake information providing system 1 according to the present invention. Such database 80 is roughly classified into a past earthquake database 81, floor response database 82, a section-by-section cabinet arrangement status database 83, and an outgoing data database 84. FIG. 4 is a view showing the structure of the database 80 of the earthquake information providing system 1 according to the embodiment of the present invention.

  The past earthquake database 81 of the database 80 stores time history waveforms (also referred to as “reference waveforms”) observed at the construction site of the building C and its surroundings in a large earthquake (reference earthquake) in the past. In addition to the reference waveform described above, the magnitude and the epicenter distance (the distance between the building C and the epicenter) are also stored.

  In the earthquake information providing system 1 according to the present invention, based on the past earthquake database 81 and the earthquake occurrence information and update information acquired from the earthquake information transmission server 60, the past reference earthquake and the currently occurring occurrence earthquakes. The correction coefficient k between them is calculated based on the following equation (1).

here,
M ₀ · X ₀ is the scale of the standard earthquake and the epicenter distance,
M · X is the scale of the generated earthquake and the source distance. M · X is a value obtained from earthquake occurrence information and update information.

Further, in the earthquake information providing system 1 according to the present invention, from the past earthquake database 81 and the earthquake occurrence information and the update information acquired from the earthquake information transmitting server 60, the shaking duration time T _d is _expressed by the following equation (2) or Calculated based on the following equation (3).

Here, c ₁ , c ₂ and c ₃ are predetermined constants, M is the scale of the occurring earthquake, and Δ is the epicenter distance of the occurring earthquake. M · Δ is a value obtained from earthquake occurrence information and update information.

Here, M is the scale of the occurring earthquake, and M is a value obtained from the earthquake occurrence information and the update information.

  Next, each floor response database 82 stored in the database 80 will be described. In the earthquake information providing system 1 according to the present invention, the prediction of the sway of the building C is obtained by response analysis using the past earthquake observation record whose amplitude is corrected as an input. The response analysis of the building C with respect to the input (the input of ground vibration) is not performed each time an earthquake occurs, but the response when the amplitude ratio is changed is calculated in advance, and the correction coefficient calculated by (1) as appropriate The response of each floor of the building C is determined in accordance with (k).

FIG. 5 is a conceptual diagram of the response analysis of the building C. As shown in FIG. Moreover, FIG. 6 is a figure which shows the relationship of the amplitude ratio which is beforehand calculated by response analysis, and the maximum response of each floor. In FIG. 6, information on all floors of the building C is omitted. A graph shown in FIG. 6 is stored in each floor response database 82, and in the earthquake information providing system 1 according to the present invention, for example, maximum response A ₁₅ of the 15th floor, maximum of the 10th floor according to the correction coefficient k. Response A ₁₀ , maximum response A ₅ of the 5th floor, etc. can be obtained.

  In the compartment-by-section fixture placement situation database 83 of the database 80, the placement situation of fixtures in each section of the building C is shown. For example, for a block as shown in FIG. 3, data such as (1st floor east) = (1st floor small), (1st floor west) = (a large number of top panel) is stored in the section-by-section cabinet layout status database 83. It is done. In the earthquake information providing system 1 according to the present invention, the information related to the possibility of falling of the furniture etc. is sent out for the section on the first floor west, which is (a lot of furniture).

Fixture for the maximum response acceleration A ₀ limitations of falling, for example, can be calculated by the following equation (4).

here,
b: width of fixture h: center of gravity height of fixture g: gravitational acceleration A: maximum acceleration of swing V: maximum velocity of swing. The values of b and h may be preset from examples of model fixtures. Alternatively, b and h may be input from the size and the like of typical fixtures of each room in the fixture arrangement status database 83, and may be set using that.

  Next, the transmission data database 84 stored in the database 80 will be described. In the earthquake information providing system 1 according to the present invention, when transmitting earthquake information of the building C, this is basically performed at four timings. The four timings are referred to as a first timing, a second timing, a third timing, and a fourth timing, respectively, in the order of earlier timing.

  The first timing is timing when the information processing apparatus 70 first acquires earthquake occurrence information from the earthquake information transmission server 60 and finishes processing related to the information.

  In addition, after the earthquake information transmitting server 60 detects the second timing and transmits the earthquake occurrence information, the information processing apparatus 70 receives this and the earthquake to the building C predicted based on the received earthquake occurrence information Timing of the arrival of

  The third timing is the timing from the arrival of the earthquake to the building C to the convergence of the sway, and is a timing in the midst of the sway occurring in the building C due to the earthquake.

  Further, the fourth timing is a timing after the earthquake has converged and the influence of the earthquake on the building C has disappeared.

  If the shaking continues for a long time, not only the inside of the room will be scattered and the person may be injured easily, but also panic may make it impossible to take appropriate action during the shaking or after the convergence of the shaking. Therefore, in the earthquake information providing system 1 according to the present invention, even if the shaking may continue for a long time even after the shaking arrives, the person in the building grasps the situation until the convergence of the shaking and the safety Transmit information during the swing to ensure security. In addition, after the shaking has converged, information is transmitted so that an appropriate initial response can be taken according to the conditions in the building estimated from the size of the shaking and the like.

  In the earthquake information providing system 1 according to the present invention, by transmitting information on the occurred earthquake at least at each of the first to fourth timings as described above according to the number of floors and sections, the shaking continues to be long. Even in the case of an earthquake, we will eliminate the psychological uneasiness of the people in the building, or prompt the people in the building to take appropriate measures. The transmission data database 84 stores transmission data for performing such information transmission.

  FIG. 7 is a view showing an example of the data structure of transmission data stored in the transmission data database 84 of the earthquake information providing system 1 according to the present invention.

  FIG. 7A shows an example of transmission data (speech, text) at the first timing when an earthquake occurs, and FIG. 7B shows transmission data at the second timing when the shaking reaches the building C 7 (C) is an example of transmission data (speech, text) at the third timing in the midst of shaking due to earthquake, and FIG. 7 (D) is after convergence of shaking of earthquake. It is an example of transmission data (speech, text) at the fourth timing.

  At each timing, transmission data is determined according to the seismic intensity predicted from the earthquake occurrence information and the update information and the duration of the shaking. The threshold value for determining this transmission data is the "reference value" in FIG. Depending on this reference value, it is determined which transmission data (voice, text) is transmitted to which section.

  The contents of the transmission data (speech, text) of FIG. 7 are constructed based on the following concept.

  Information sent during the earthquake is not only the size and duration of the shaking, but also the possibility of falling or moving furniture or fixtures that may cause injury to the person, such as anxiety or difficulty of movement. Related to the influence of and on the influence of structures and non-structural members. As information transmission, first, when the shaking reaches, tell the residents about the security of the visitors (the second timing).

  Specifically, based on the relationship between the magnitude of shaking and the degree of behavioral difficulty investigated by the subject experiment as shown in FIG. Give instructions in short as appropriate so that you can take a safe posture as needed, such as “Such as it is”. Next, when the shaking continues for a while, information on the time until the shaking converges and the influence of the shaking on people and buildings so that the resident can not understand the situation and feel uneasy Tell (3rd timing).

  Here, from the relationship as shown in FIG. 9, the magnitude of the shaking is represented by the influence on people, or it is represented by the influence on the structural frame, such as noticing earthquake noise from the wall or ceiling but not affecting the earthquake resistance. In order to understand the situation in the middle of the swing and to be cool. Furthermore, if there is a possibility that the shaking will continue for a long time, information will be sent out at regular intervals, and it will be understood that the time for the shaking to converge has become shorter, so that the anxiety of the building will not increase. Make it

  After the earthquake sway has converged, the situation in the building predicted from the size of the sway, locations with the risk of injury due to falling objects, presence or absence of the need for safety actions such as evacuation, and prevention of secondary damage Transmit information such as inspection points to do (the fourth timing). In addition, if the impact on people is expected to be large, we encourage them to respond calmly so as not to panic.

  Next, an outline of the process flow of the earthquake information providing system 1 according to the present invention configured as described above will be described based on FIG.

  In FIG. 10, when the earthquake information providing system 1 according to the present invention acquires earthquake occurrence information from the earthquake information transmitting server 60 in step S100, the process proceeds to step S101 and the seismic intensity for each floor (the method described above) Predicted seismic intensity) and arrival time until arrival of an earthquake (arrival predicted time) are calculated.

  In step S102, it is determined whether the predicted seismic intensity is 4 or more or less than 4. If the determination result in step S102 is less than 4, the processing of the earthquake information providing system 1 according to the present invention is ended.

  On the other hand, if the determination result in step S102 is 4 or more, the process proceeds to step S103, and information transmission at the first timing is performed based on the transmission data of FIG. 7A based on the speaker 110, signage monitor 120, and personal computer group 130. Etc. sends information to people in the building C. For example, if the seismic intensity is 6 or less, voice or text display such as "You will expect a very large shake after 10 seconds. Take a safe posture on the spot." Is displayed.

  When the earthquake information provision system 1 according to the present invention acquires update information from the earthquake information transmission server 60 in step S200 at the timing of the arrival time of the earthquake, the process proceeds to step S201, and each floor is processed by the method described above. The seismic intensity for each time (predicted seismic intensity) and the time (duration time) that the earthquake lasts are calculated.

  In step S202, it is determined whether the predicted seismic intensity is 4 or less or more than 4. If the determination result in step S202 is 4 or less, the process proceeds to step S400.

  On the other hand, if the determination result in step S202 is more than 4, the process proceeds to step S203. In step S203, it is determined whether the duration is less than 20 seconds or more than 20 seconds. If the determination result in step S203 is less than 20 seconds, the process proceeds to step S400.

  On the other hand, if the determination result in step S203 is 20 seconds or more, the process proceeds to step S204, and information transmission at the first timing is performed based on the transmission data of FIG. 7B based on the speaker 110, signage monitor 120, personal computer group The information transmitting unit such as 130 transmits information to the person in the building C.

  In the case where the earthquake intensity of the limit is that the fixture falls down, the information transmission in step S204 stores the information related to (small amount of fixtures) and (large number of fixtures) stored in each section in the fixture arrangement status database 83 classified by section It is used.

  For example, the message of A2 in FIG. 7 (B) is adopted for a section stored as (small fixtures), and “the shaking of the level which can not stand is continued for several tens of seconds. And take a safe posture. ”Voice and text are displayed.

  On the other hand, the message of A2 'in FIG. 7 (B) is adopted for the section stored as (a lot of furniture), and "the swing of the furniture falls over for several tens of seconds. "Please take a safe posture." Such as voice and text display.

  Thus, in the earthquake information providing system 1 according to the present invention, it is possible to transmit the possibility of falling of the fixtures due to the earthquake to the people in the building C.

  For example, when the earthquake information providing system 1 according to the present invention acquires update information from the earthquake information transmitting server 60 in step S300 at a timing 20 seconds after the arrival time of the earthquake, the process proceeds to step S301 and proceeds first. According to the method described, the seismic intensity (predicted seismic intensity) for each floor and the time (duration) in which the earthquake lasts are calculated.

  In step S302, it is determined whether the duration is less than 10 seconds or greater than 10 seconds. If the determination result in step S302 is less than 10 seconds, the process proceeds to step S400.

  On the other hand, if the determination result in step S303 is 10 seconds or more, the process proceeds to step S303, and information transmission at the third timing is performed based on the transmission data of FIG. 7C based on the speaker 110, signage monitor 120, personal computer group The information transmitting unit such as 130 transmits information to the person in the building C. For example, if the time until convergence of the shaking is 60 seconds or more, speech or text display such as "Still shaking for a while. Keep safe posture." Is displayed.

  For example, when the earthquake information providing system 1 according to the present invention acquires update information from the earthquake information transmission server 60 in step S400 at a timing 5 seconds after the predicted convergence time of the earthquake, the process proceeds to step S401. According to the method described above, the seismic intensity (predicted seismic intensity) for each floor and the time for which the earthquake lasts (duration time) is calculated.

  Subsequently, the process proceeds to step S402, and information transmission at the fourth timing is based on the transmission data of FIG. 7D from the information transmission unit such as the speaker 110, the signage monitor 120, the personal computer group 130, etc. Send information to people in

  As the reference value used in FIG. 7D, the maximum seismic intensity predicted from the earthquake occurrence information and the update information can be used. For example, if the predicted maximum seismic intensity is "more than 5 seismic intensity," speech or text such as "Please confirm the safety of the surroundings and restart the business" is displayed.

  In the above flow, the earthquake information providing system 1 according to the present invention is configured to predict the seismic intensity, duration, etc. only with the information from the earthquake information transmitting server 60, but if it is in the building C or around the building C In the case where a seismograph is provided, it is possible to perform processing that utilizes information of the seismometer as appropriate. For example, by providing a seismograph, it is possible to determine the arrival of the earthquake to the building C, the determination of the convergence, and the like with higher accuracy.

  As described above, in the earthquake information providing system 1 according to the present invention, since the information transmitting unit transmits transmission data related to the earthquake at a plurality of timings after the occurrence of the earthquake, the earthquake information providing system 1 according to the present invention According to the above, even in the case of a long-lasting earthquake, depending on the number of floors in the building, eliminate the psychological unrest of the people in the building, or prompt the people in the building to take appropriate measures. It becomes possible.

  In addition, according to the earthquake information providing system 1 according to the present invention, it is possible to inform the building C residents of the size of the shaking and the indication of the continuation time with high accuracy for earthquakes that shake for a long time. As well as preparation before it comes, it can reduce anxiety during swings and lead to an appropriate recovery response (accelerated) after the swings are settled.
