Abstract

To make it possible to provide information regarding safety against earthquakes, in response to a request of a customer of a management building, to the customer by a simple structure.SOLUTION: Measured data (acceleration information, inclination information) is sent from a measurement sensor 2 of a management building 1 to a seismic strength determination server 30 via a measurement capture server 20. The seismic strength determination server 30 sends the measured data to a building state analysis server 40 only when the acceleration information is larger than a threshold, and analyzes the measured data to create and preserve building status data (numeric data) regarding the safety of the management building 1. A manager terminal 70 can browse, in a manager connection server 60 upon a request, status display data that is obtained by processing the building status data and expressed in a recognizable language regarding safety. Information of the management building 1 and the configuration of various servers can be executed from a customer management server 50.SELECTED DRAWING: Figure 1

Description

The present invention relates to a building diagnosis system for earthquakes that measures and diagnoses conditions based on measurement data from managed buildings after an earthquake, primarily wooden structures, and notifies the manager of the managed building, etc.

Conventionally, an earthquake detection device has been proposed that detects data related to building vibrations, generates features for earthquake detection, and uses teacher data management means to learn using the teacher data when making earthquake detection (Patent Document 1).
In addition, although there is no specific description regarding the measurement of earthquake motion, a device has been proposed that diagnoses the safety of a building from measured earthquake motion based on the energy absorption capacity calculated from the structure's natural period, mass, wall magnification factor, etc. (Patent Document 2).
In addition, a program has been proposed for diagnosing buildings by performing a secondary analysis using a method different from the primary analysis from sensor signals obtained by measuring the acceleration and other vibration data of the building at specified time intervals (Patent Document 3).

JP 2016-156712 A Patent Publication No. 7004361 Patent Publication No. 6762631

Of the above-mentioned conventional technologies, the technology of Patent Document 1 requires a teacher data set that corresponds to the features for earthquake judgment, which requires a huge amount of preparation before operation and is not suitable for simple building diagnosis systems.
Furthermore, the technology of Patent Document 2 requires a large amount of information for diagnosis, such as the requirement of the mass of the structure to be diagnosed in order to handle energy, and is therefore not suitable for simple building diagnosis systems.
In addition, in Patent Document 3, a primary analysis and a secondary analysis are performed on one vibration data, which allows for more flexible operation, but since two analyses are required, it is not suitable for simple building diagnosis systems.

The present invention solves the above problem by sending the measurement data to a building condition analysis server after processing in the earthquake intensity judgment server, and further by storing customer data including each server's setting data in a customer management server for each server, and connecting the customer management server to each server.

That is, the first invention is a building diagnosis system for use in an earthquake, characterized in that it comprises a measuring device, a customer management server, a main server, and an administrator connection server, and is configured as follows.
(1) The measurement device is installed in a management building to acquire measurement data.
(2) The customer management server accumulates and processes customer data including managed building data, manager data for the managed building, and configuration data for each server for each manager or for each managed building.
(3) The main bar was configured as follows:
(a) receiving, in the event of an earthquake, the measurement data from the measuring device for each of the managed buildings;
(b) determining whether the earthquake intensity data included in the measurement data is equal to or greater than a preset earthquake intensity;
(c) if the earthquake intensity is greater than or equal to a preset earthquake intensity,
The measurement data is stored for each managed building and for each earthquake, and from the measurement data stored in the measurement data server,
The stored measurement data is subjected to a predetermined analysis to generate and store building condition data relating to the safety of the managed building.
(4) The administrator connection server is
connected to the main server;
Connecting the information terminal of the manager,
In response to an operation from the information terminal of the administrator,
The building condition data of the managed building is provided to the information terminal of the manager.

The second invention is a building diagnosis system during an earthquake, comprising a measuring device, a customer management server, a measurement data input server, an earthquake intensity judgment server, a building condition analysis server, and an administrator connection server, and configured as follows:
(1) The measurement device is installed in a management building to acquire measurement data.
(2) The customer management server accumulates and processes customer data including managed building data, manager data of the managed building, and setting data of each server for each manager or for each managed building. (3) The measurement data import server
When an earthquake occurs, the measurement data is acquired from the measuring devices installed in each managed building at the time of the earthquake occurrence, and is accumulated for each managed building.
(4) The earthquake intensity assessment server is
The measurement data is received from the measurement data import server, and for each managed building, it is determined whether the earthquake intensity data included in the measurement data is equal to or greater than a preset earthquake intensity.
(5) The building condition analysis server has the following configuration.
(a) for each such managed building:
When the earthquake intensity judgment server judges that the earthquake intensity is equal to or greater than a preset intensity,
(b) receiving the measurement data of the managed building from the earthquake intensity determination server, for each managed building and for each earthquake,
From the measurement data stored in the measurement data server,
We will create building status data on the safety of the managed building in the event of an earthquake,
(c) The building condition data is stored for each managed building and for each earthquake.
(6) The administrator connection server is
Connected to the building status analysis server,
Connecting the information terminal of the manager,
In response to an operation from the information terminal of the administrator,
The building condition data of the managed building is provided to the information terminal of the manager.

The building diagnosis system for earthquakes according to the second invention is configured as follows.
(1) The measurement data shall be data measured by at least two sensor devices installed vertically in the managed building,
(2) The sensor device is configured to integrally incorporate sensors capable of measuring acceleration measurement information and tilt measurement information,
(3) The earthquake intensity data is data supplied from acceleration measurement information of the sensor device.

The earthquake intensity determination server is a building diagnosis system for earthquakes that extracts only acceleration information from the measurement data of the measuring device and determines the earthquake intensity by only comparing whether the acceleration information is greater than preset acceleration information.

The building diagnosis system for earthquakes described in the second invention imports structural test data, including wall shear test data related to managed buildings or general-purpose data, into a building condition analysis server, creates supplemental building condition data, stores the supplemental building condition data in a building condition database, and makes the supplemental building condition data and structural test data viewable from an administrator terminal.

By setting up an earthquake intensity judgment server, only measurement data with earthquake intensity levels equal to or greater than a preset level is sent to the building condition analysis server, which reduces the capacity of the building condition analysis server, which requires the most processing power. In addition, the configuration information for each server is stored in the customer management server and connected to each server, making it possible to set the earthquake intensity judgment threshold and the analysis method for the building condition analysis server according to the administrator's wishes, making it possible to perform customized diagnosis of managed buildings for each customer. Therefore, despite the simple configuration of a single system, it is possible to provide information that is more in line with the administrator's needs.

1 is a schematic diagram showing a configuration of a system according to the present invention; FIG. 13 is a schematic diagram showing another configuration of the building condition determination server in the system configuration of the present invention. FIG. 2 is a schematic diagram illustrating the placement of diagnostic sensors for use in the system of the present invention.

An embodiment of the invention will be described with reference to the drawings.

1. System configuration

The building diagnosis system 100 for earthquakes is composed of a managed building 1, a measurement sensor 2 installed in the managed building 1, a main server 10 that receives and processes data from the measurement sensor 2 (measurement data import server 20, earthquake intensity judgment server 30, building condition analysis server 40), an administrator connection server 60 connected to the main server 10, an administrator terminal 70 connected to the administrator connection server 60, and a customer management server 50.
Typically, the measurement data from the measurement sensor 2 is sent to the main server 10 (measurement data server 20) via various communication means, where it is imported and processed within the main server 10 as follows.

(1) Managed building 1
The managed building 1 is the target of this building diagnostic system and is mainly a wooden building. Managers such as the resident, owner, construction company, and maintenance company are set for the managed building 1, and information about the managed building 1 is managed in a customer management database 51 of a customer management server 50.

(2) Measurement sensor 2
A measurement sensor 2 is attached to a management building 1. The measurement sensor 2 is a sensor device equipped with an acceleration measurement function and an inclination measurement function built into one small case. In other words, acceleration data and inclination data are measured from one measurement sensor 2 and sent to a measurement data import server 20.
It is desirable to use at least two (plural) measurement sensors (sensor devices) 2, and for example, they may be arranged as follows (FIG. 3).
(a) Using two measurement sensors 2,
- Install it on one floor of the building (the first floor in this case) - near the ceiling and near the floor (Figure 3 (a)).
(b) Using two measurement sensors 2,
-On two floors of the building,
- Install indoors (room) near the first floor or second floor (Figure 3 (b)).
(c) Using four measurement sensors 2,
・On the first and second floors of the building,
- Install indoors (room) near the ceiling and floor on the first floor and near the ceiling and floor on the second floor (Figure 3 (c)).
Furthermore, in wooden structures, it is desirable to install the measurement sensor at the joint of the column and beam, where the effects of an earthquake are most apparent and the overall behavior can be grasped. In this embodiment, since it is assumed that the measurement sensor will be applied to the managed building 1 as a repair after the building is constructed, the measurement sensor 2 is installed on the wall of the managed building 1 (as close to the joint as possible), although the accuracy is somewhat reduced in understanding the behavior. Note that the measurement sensor (threshold value of the earthquake intensity determination server 30) and the analysis method of the building condition analysis server 40 can be different depending on the installation position.
Generally, the cost naturally increases as the number of installed measurement sensors 2 increases, so the number of installed measurement sensors 2 is selected appropriately, but multiple sensors are required. The number and installation locations of the measurement sensors 2 can be set by the administrator, and are customer information stored in the customer database 51 of the customer management server 50.

(3) Customer management server 50
The customer management server 50 also stores information related to the managed building 1 which is the subject of this building diagnosis system 100, customer information related to the managed building 1, and various setting data for the earthquake intensity determination server 30 and building condition analysis server 40 according to the customer.
(a) Information on managed buildings includes:
- Location of the management building 1;
- The construction method used to construct the management building 1;
- Includes the structure of architectural hardware used in the managed building 1.
(b) The manager information (manager) of the managed building 1 is as follows:
- A contractor undertaking the maintenance of the managed building 1;
- The construction contractor of the managed building 1,
The owner of the managed building 1, the resident of the managed building 1, etc. are set for each managed building 1.
In addition, a person in charge is assigned among the managers for each managed building 1, and each function described later is selected by the person in charge.
(c) Threshold value for each managed building 1 in the earthquake intensity determination server 30 (d) Analysis contents in the building condition analysis server 40 (e) Selection and setting of the administrator terminal 70 to be connected to the administrator connection server 60, and setting of the display contents of the administrator terminal 70

(4) Measurement data import server 20
The measurement data import server 20 imports the measurement data (acceleration data, tilt data) from the measurement sensor 2 via various communication means, and temporarily stores the data in the measurement database 21. The measurement sensor 2 transmits measurement data when the data is a relatively large value (large acceleration value, large tilt value) depending on the accuracy and settings of the measurement sensor 2 itself.
Although the measurement data is temporarily stored in the measurement database 21, all the measurement data can be sent to the earthquake intensity judgment server 30 and the building condition analysis server 40.

(5) Earthquake intensity judgment server 30
The earthquake intensity determination server 30 compares the acceleration data from the measurement data with preset threshold data. In other words, it determines whether the acceleration data (which is linked to the so-called seismic intensity data) caused by the earthquake is large or small. This threshold data is set by the customer database 51 of the customer management server 50, etc.
(a) If the acceleration data is greater than the threshold data, the acceleration data and other measurement data (here, tilt data) of the same managed building 1 are sent to the building condition analysis server 40. At this time, once the measurement data has been sent to the building condition analysis server 40, the measurement data stored in the measurement database 21 can also be deleted.
(b) If the acceleration data is smaller than the threshold data, it is considered that the shaking is not strong enough to determine the building condition, so the following process is terminated. At this time, the measurement data stored in the measurement database 21 can also be deleted at the same time.

(6) Building condition analysis server 40
The measurement data (acceleration data, inclination data) sent from the earthquake intensity assessment server 30 is subjected to various data processing calculations to create building condition data, and this building condition data is stored in the building condition database 41 for each managed building 1 and for each earthquake that has occurred.
In this case, the creation of the building condition data can employ various analysis methods that have been conventionally applied. Also, the analysis method can be set for each managed building 1, and the analysis method is set based on information in the customer database 51 of the customer management server 50, etc.
Moreover, the building condition data here is generally numerical data.

(7) Administrator connection server 60
An administrator terminal 70 is connected to the administrator connection server 60 .
The administrator connection server 60 creates status display data in understandable language such as “safe,” “requires inspection,” “urgent inspection,” and “danger” based on the building status data (numerical data) stored in the building status database 40 based on the set thresholds, and stores the data in the administrator provided database 61.
The contents of the status display data are set for each manager and managed building 1 according to instructions from the management terminal 70 or the information in the customer database of the customer management server 50.
In addition, various information about the managed building 1 is also obtained from the customer database 51 of the customer management server 50 and stored in the administrator-provided database 61 as administrator-provided data.

(8) Administrator terminal 70
The administrator terminal 70 is connected to the administrator connection server 60, and can obtain administrator-provided data from the administrator-provided database 61 within the permitted range based on instructions and settings from the administrator terminal 70. In addition, it is also possible to set it so that building condition data from the building condition database 41 of the building condition analysis server 40 can be obtained based on settings from the customer information in the customer management database 51 of the customer management server 50 and settings on the administrator terminal 70. Settings for selecting various information to be sent to the administrator terminal 70 are also set from the customer management server 50.
As described above, the administrator terminal 70 is intended for various people related to the managed building, such as construction companies, maintenance managers, and owners, and among the administrator terminals 70, administrators who can connect to the administrator connection server 70 are set from customer information in the customer database 51 of the customer management server 50.
In addition, the administrator terminal 70 can be configured on the customer management server 50 so as to connect directly to the customer management server 50 or via the administrator connection server 60 to modify various customer information in the customer management database of the customer management server 50.

2. Operation of the building diagnostic system 100

(1) When an earthquake occurs, measurement data (acceleration information, tilt information) is sent from the measurement sensor 2 installed in the managed building 1 to the measurement data import server 20 via various communication means such as Wi-Fi (in some cases, this may be excluded in the case of a minor earthquake), and is stored in the measurement database 21. Measurement data is stored for each managed building 1 and each earthquake.

(2) Of the measurement data, the acceleration information is immediately sent to the earthquake intensity assessment server 30 and compared with a preset threshold value. The threshold data is set as standard, but can be freely set for each manager, each managed building 1, etc. by changing the information in the customer database 51 of the customer management server 50 from the manager terminal 70, etc., as described above.
(a) When the acceleration data is greater than the threshold data, the acceleration data and tilt data are sent from the measurement database 21 to the building condition analysis server 40. Note that, as described above, once the measurement data is sent to the building condition analysis server 40, the measurement data stored in the measurement database 21 can also be set to be deleted.
(b) If the acceleration data is smaller than the threshold data, the following process is terminated. Note that the measurement data can also be set so that the measurement data stored in the measurement database 21 is deleted once it has been sent to the building state analysis server 40.

(3) Next, the building condition analysis server 40 performs a preset analysis process on the measurement data (acceleration data, tilt data), creates building condition data, and stores it in the building condition database 41 for each managed building 1 and for each earthquake. Here, the analysis method is set as standard, but as described above, by changing the information on the building condition analysis server 40 from the manager terminal 70 or using customer information in the customer database 51 of the customer management server 50, it is possible to freely select from a number of analysis methods, such as for each manager or for each managed building 1, and also to set the necessary numerical values.
As mentioned above, building condition data is generally numerical data.

(4) Next, when a request to view building status data is made from the administrator terminal 70 to the administrator connection server 60, the administrator connection server 60 retrieves the building status data of the managed building 1 instructed by the administrator terminal from the building status database 41, converts the building status data of the building status server 41 into status display data such as “safe”, “requires inspection”, “urgent inspection”, “dangerous”, etc. based on a preset conversion function (threshold value; instruction from the customer information in the customer database 51 of the administrator management server 50), and transfers the building status data to the administrator terminal 70 via the administrator connection server 60.
Also, in the above, the status display function can be provided in the administrator connection server 60 instead of the building status analysis server 40, and processing can be performed as follows: That is, when a request to view building status data is made from the administrator terminal 70 to the administrator connection server 60, the administrator connection server 60 retrieves the building status data of the managed building 1 from the building status database 41, converts the building status data into status display data such as "safe", "inspection required", "urgent inspection", "danger", etc. based on a conversion function (threshold value; instruction from the administrator management server) preset in the administrator connection server, and transfers it to the administrator terminal 70.

(5) The administrator terminal 70 can be configured to connect to the administrator connection server 60 at any time and display building status data (status display data) for the managed building 1.

3. Other embodiments

(1) In the above embodiment, a structural test database 80 including various structural data such as wall shear test data can be set up, and the building condition judgment analysis server 40 can be connected to the structural test database 80 to import the structural experiment data, create supplemental building condition data for the managed building 1, and store the supplemental building condition data in the building condition database 41 (FIG. 3). The structural test database 80 contains information on the managed building 1 or general-purpose information.
In this case, the administrator terminal 70 can be set up so that the supplemental building status data or the supplemental building status data that has been processed so as to be comprehensible can be viewed via the administrator connection server 60.
Similarly, the administrator connection server 60 can be connected to the structural test database 80 so that only various structural data can be viewed (not shown).

(2) In addition, in the above embodiment, if an earthquake occurs, the current state of the managed building can be visually confirmed, and on-site visual inspection data for the managed building can be created using images and text, and stored in a building condition analysis server or the like, and can be viewed from an administrator terminal (Figure 2). In this case, the building condition data can be supplemented by taking into account the visual inspection data, such as by correcting it.
