Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a service system for storing, analyzing, and providing seismic waveform information.
[0002]
[Prior art]
Conventional general means for collecting earthquake information is to collect the output of a seismometer installed by the Japan Meteorological Agency or various research institutes either online or offline. The number of seismic information that can be collected from these is less than 1,000 throughout Japan.
In addition, individual operators collect data independently within the scope of their own company, such as a major construction company installing its own seismometer on a part of the building it has built and collecting data. There are also examples. In such a case, the number of seismic information that can be collected is even smaller than the above.
[0003]
On the other hand, Japanese Patent Application Laid-Open No. 2001-130848 proposes an "elevator earthquake damage prediction system". This is to record the regional distribution of the shaking intensity in the earthquake (ground motion distribution) in association with the epicenter and magnitude of the earthquake at that time in order to quickly grasp the situation of elevator damage at the time of the earthquake. In addition, when an earthquake occurs, the distribution of ground motion is estimated using records near the epicenter, and the damage to the elevator is predicted. However, in Japanese Patent Application Laid-Open No. 2001-130848, the seismic waveform is not recorded, but the intensity of shaking is used as an index, and in particular, a unique index called an SI value is used.
[0004]
[Problems to be solved by the invention]
However, with the above-mentioned general collection means, the number of installed seismometers is small, and for example, ground information (ground structure, responsiveness to earthquake) in the unit of city or ward in an urban area or in the unit of a smaller area. Is difficult to estimate.
Even if the seismographs are increased to the extent that the above is possible, it is not easy to construct a means for collecting the output of the seismographs in a short time, that is, a network for transmitting and receiving the data of the earthquake information. In addition, it is difficult to perform maintenance management for maintaining the performance of many seismographs.
[0005]
The proposal disclosed in Japanese Patent Application Laid-Open No. 2001-130848 is a method for estimating the earthquake damage of an elevator on a certain ground, and the provision of the information is performed by a person related to the elevator (a maintenance company, a manager, Etc.), and does not collect and provide ground information extensively. In Japanese Patent Application Laid-Open No. 2001-130848, the input of earthquake information is simply by "earthquake information input means". Instead of inputting an earthquake waveform, an index of the intensity of shaking is input from a keyboard or the like. It is.
[0006]
The present invention has been made in order to solve the above-described problems. Instead of the conventional general earthquake information collecting means, the present invention collects information of a large number of seismometers and obtains ground information in a relatively small area unit. It is also possible to estimate information and provide that information widely. Unlike Japanese Patent Application Laid-Open No. 2001-130848, instead of inputting the magnitude of the indexed shaking, the seismic waveform itself is input and used as a database.
[0007]
[Means for Solving the Problems]
The earthquake data providing service of the present invention stores seismometers installed in a plurality of buildings in which elevators are installed, a maintenance network of the elevators, and individual information of the elevators including location information of the buildings in which the elevators are installed. Information that combines the output data of the seismometer collected via the maintenance network and the location information of the building in which the elevator is installed extracted from the elevator individual information database. It is characterized by comprising a processing device and an earthquake information database for storing earthquake data combined by the information processing device.
[0008]
Further, the present invention is characterized in that a secondary database obtained by stratifying and processing the earthquake data of the earthquake information database is provided.
[0009]
Further, a means for providing at least one of the earthquake data and the secondary data is provided.
[0010]
Further, the invention is characterized in that there is provided means for combining the earthquake data with the epicenter information and the scale information of the earthquake.
[0011]
It is also characterized in that it is a secondary database stratified by the location of the building.
[0012]
It is also characterized by a secondary database that is stratified by building usage.
[0013]
Further, at least one of the earthquake data and the secondary data is provided via a network line.
[0014]
Further, at least one of the seismic data and the secondary data is provided to an owner or a manager of the elevator via a maintenance circuit network of the elevator.
[0015]

Embodiment 1 FIG.
FIG. 1 is a system configuration diagram of Embodiment 1 of an earthquake data providing service according to the present invention, and FIG. 2 is an enlarged view of the vicinity of an elevator in the earthquake data providing service. In the figure, reference numeral 1 denotes a maintenance network of an elevator, 1a denotes a trunk line of a maintenance network 1 of an elevator, 1b denotes a branch line of a maintenance network 1 of an elevator, 2 denotes an elevator connected to the maintenance network 1 of an elevator, and 2a denotes an elevator 2 3 is a building, 4 is a building, 4 is a seismometer with an output line connected to the communication device of the elevator, 5 is a server, 6 is a computer for information processing, and 7 is individual information of the elevator.

[0016]
When an earthquake occurs, the building 2 shakes, and when the shaking exceeds a certain level (for example, seismic intensity 2 or more), the seismometer 4 installed in the building is activated, and the output is transmitted to the communication device 2a. Although the output of the seismometer is directly an analog waveform, the output is digitized by the AD converter and transmitted from the communication device 2a to the server 5 via the maintenance network 1 of the elevator. The output of the seismograph digitized and transmitted to the server 5 is extracted from the elevator individual information database 7 by the information processing computer 6, and the location information of the building where the elevator is installed, the use information of the building, the architecture The structure information is added and stored in the earthquake database 8. The information on the epicenter and magnitude of the earthquake announced by the Japan Meteorological Agency is added to the earthquake data by the external information input device 9 and stored in the earthquake database 8.
[0017]
Here, the building use information is, for example, information indicating the use of the building such as office use, hospital use, and commercial use. The building structure information is information such as a flexible structure and a rigid structure, and information such as the number of floors.
[0018]
The earthquake data stored in the earthquake database 8 is stratified by the information processing computer 6 according to location information, and is normalized in relation to the epicenter and scale information of the earthquake to obtain ground data for each location. , Are stored in the secondary database 9.
[0019]
In addition, the earthquake data accumulated in the earthquake database 8 is stratified by use by the information processing computer 6, and the strength of the ground is corrected by ground data for each location to obtain information for each use, It is stored in the secondary database 9.
[0020]
The earthquake data stored in the earthquake database 8 is stratified by the information processing computer 6 according to the structure of the building, and the strength of the ground is corrected based on the ground data of each location. And stored in the secondary database 9.
[0021]
These earthquake data and secondary data are transmitted to a user's personal computer 13 via a general network line 12 and provided for a fee or free of charge.
[0022]
The owner and the manager of the elevator can be provided with earthquake data and secondary data via the maintenance network 1 for the elevator. Of course, a general network line 12 can be used.
[0023]
Further, these earthquake data and secondary data can be output to an electromagnetic medium such as a magnetic tape, a flexible disk, an MO, a CD-ROM, and a DVD via the off-line output device 11 and provided off-line.
[0024]
In FIG. 2, the seismometer 4 is illustrated as being installed on the lowest floor of the building 2, but is not necessarily limited to this. Since it is close to the ground, it is preferable to place it on the lowest floor or in the pit of an elevator, but it may be located elsewhere if appropriate correction means are provided. Further, the installation of the seismometer is not limited to one place in the same building, and a plurality of seismometers may be placed in one building. In the case of arranging a plurality of objects, if the objects are arranged in the vertical direction of the building, ground information and response information of the building can be obtained.
[0025]
As of 2002, a single major elevator maintenance company alone provides a remote monitoring service for more than 15,000 elevators via a maintenance line.
Therefore, if a seismometer is installed in a building equipped with an elevator that performs the above-described remote monitoring service, it is possible to obtain 15 times or more the number of pieces of earthquake information as compared with the conventional case.
Most elevators are installed in urban areas, so in urban areas only, earthquake information can be obtained twice or more times, that is, 30 times or more as compared with the past.
In addition, since the remote monitoring service via the maintenance line tends to increase not only for newly installed elevators but also for existing elevators, more earthquake information can be obtained.
[0026]
If a large number of pieces of earthquake information can be obtained as described above, it is possible to estimate ground information on a regional basis in accordance with the information. The principle is based on a method of grasping vibration characteristics by multi-point excitation and multi-point response well known in engineering. In the case of an earthquake, the excitation point corresponds to the epicenter and the response point corresponds to the point where the seismometer was installed. By increasing the number of installed seismometers as in the present invention, the number of response points increases, so that finer vibration characteristics (= ground information) can be understood.
[0027]
Even in the same shaking earthquake, urban areas that are densely populated are said to be severely damaged by earthquakes. As described above, since the number of installed elevators is large in urban areas, it is preferable to use the maintenance network of the elevators as a means for obtaining disaster prevention information on earthquakes.
[0028]
Also, since the elevators are regularly patroled by maintenance personnel for maintenance, there is an advantage that the maintenance management of the installed seismometer can be performed simultaneously with the maintenance of the elevators.
[0029]
In addition, many elevators are already equipped with seismometers, which has the advantage that the cost of installing a new seismometer can be reduced.
[0030]
The destination of the data assumed in the earthquake information providing service, that is, the user of the data is, for example, as follows.
Government agencies and local governments that conduct earthquake countermeasures, universities and research institutes that conduct earthquake research, architectural design offices, building companies, owners and managers of buildings where the seismometers are installed.
However, it is not limited to this.
[0031]
Governments and municipalities can take more appropriate disaster countermeasures if they know the geological information of each region.
[0032]
Universities and research institutes have access to much seismic information, which accelerates research.
[0033]
For architectural design firms and architectural companies, this is a guide to determine which areas require seismic design and how effective it is in designing new buildings and renovating existing ones. In addition, since the strengths of each use and structure of the building are clarified, it is easy to take countermeasures for each use and structure.
[0034]
For the owners and managers of the building where the seismograph is installed, the strength of the ground in the area and the strength of the building's seismic resistance will be clear. It becomes easy to examine the refusal.
[0035]
