  The present invention incorporates, for example, an elevator inspection technique, which is a part of a conventional building, into a conventional earthquake measurement system for an entire building, and can easily install an earthquake measurement facility for the entire building, and evaluate earthquake damage. The present invention relates to a seismic damage measurement system and a seismic damage measurement method.

Generally, in a plant, for example, a power plant, the soundness of structures such as buildings, equipment, and piping at the time of an earthquake should be provided with measuring means for measuring information related to structures such as accelerometers, strain gauges, and displacement meters. Is being monitored.
The data measured by these measuring means is sent to a data monitoring room, etc., away from the site, collected and analyzed by a data analysis computer, etc., and the soundness evaluation after the occurrence of earthquakes such as buildings, equipment, piping, etc. Used for safety confirmation.

  These measurement means are wired with a power supply cable, a measurement cable for transferring measurement data, or a network cable for transmission as digital data.

  Recently, as a digital measurement data collection system for collecting measurement data, a measurement device and a data collection computer can perform two-way communication, for example, a wired telephone, a wireless telephone represented by PHS, a wireless LAN, etc. A measurement system that performs data communication is used.

  As an example, a state monitoring system at the time of an earthquake has been proposed for the purpose of providing seismic measurement equipment in power plants and buildings and providing evaluation data for evaluating the soundness of structures from the measurement data. Yes. In this case, seismometers are installed at various locations in the building, and the seismometer power supply and cables for observation signals are wired in the building, which requires extensive installation work (for example, Patent Document 1).

  In addition, there is a proposal for reducing wiring by digitizing measurement data at observation points and transferring the measurement data to a data collection computer via a network cable for the purpose of reducing the cost of data transfer for earthquake measurement. Also in this case, the network cable that is the backbone needs to be wired in the building from the observation point (for example, Patent Document 2).

Also, as an inspection system after an elevator earthquake, a CCD camera attached to the elevator car is used to measure the horizontal cross-sectional shape in the hoistway while raising and lowering the elevator, and the horizontal cross-sectional shape at each height is collected. A system has been proposed (for example, Patent Document 3).
Similarly, there has been proposed a system that detects an abnormality of a hoistway from an image change before and after an earthquake based on an image of a camera attached to an elevator car (for example, Patent Document 4).

Construction was necessary.

  Therefore, in order to construct a new seismic measurement system in an existing building, etc., enormous construction funds, labor and time were required. For this reason, there is a limit in the system configuration in order to install an earthquake measurement system in an existing building and monitor earthquake damage.

  On the other hand, as an inspection system for elevators that are part of buildings, a system for inspecting earthquake damage in hoistways has been proposed as described above, but it is possible to monitor earthquake damage related to the entire building. There is nothing.

In addition, it is possible to easily evaluate earthquake damage.

  Embodiments of an earthquake damage measurement system according to the present invention will be described below with reference to the drawings.

Example 1 will be described with reference to FIGS. 1A, 1B, and 2. FIG.
FIG. 1A shows the configuration of the first embodiment. That is, the elevator hoistway 4 passes between the floors 2 of the building 1, that is, the interlayer 3, and the displacement meter 5 that measures the interlayer displacement between the floors 2 through which the hoistway 4 passes is A displacement gauge base 6 installed on each floor 2 of the road 4 is attached. A target 7 for supplying a displacement amount to the displacement meter 5 is attached to a target base 8 installed on each floor 2 of the hoistway 4.

  Examples of the displacement meter 5 include a laser displacement meter and an eddy current type displacement meter as a non-contact type, and a capacitance type displacement meter and a strain gauge type displacement meter as a contact type. Examples of the target 7 include a laser reflector, an induced surface of eddy current, and an electrode surface on one side of the capacitor.

  By causing the displacement meter 5 and the target 7 to face each other in the interlayer 3 of each floor 2 of the hoistway 4, the interlayer displacement of each floor 2 is measured. The signal measured by the displacement meter 5 is collected via a cable 9 installed in the hoistway 4.

  The signal measured by the displacement meter 5 can be digitized by A / D conversion and digitally transferred by a LAN cable installed in the hoistway 4.

  In the first embodiment configured as described above, when an earthquake occurs, interlayer displacement occurs mainly horizontally (in the direction of the arrow) in the interlayer 3 of each floor 2 of the building 1. The inter-layer displacement is measured by a displacement meter 5.

  As shown in FIG. 1B, when a large damage occurs in the interlayer 10, the displacement meter 11 measures the large interlayer displacement and outputs measurement data. The signal measured by the displacement meter 5 is collected via the cable 9 installed in the throughway 4 for the hoistway, as in FIG.

  In either case of FIG. 1 (A) or FIG. 1 (B), the damage evaluation data collection device 37 shown in FIG. 2 uses this measurement data as the interlayer displacement data of each floor 2 stored in the interlayer database in advance. And assessing the soundness of the building by estimating the occurrence of large earthquake damage in the interlayer 10.

  FIG. 2 is a block diagram showing a generalized configuration diagram of the earthquake damage measurement system shown in FIGS. 1 (A) and 1 (B).

  This earthquake damage measurement system is composed of interlayer displacement measurement means 33 and building soundness evaluation means 35.

  The inter-layer displacement measuring means 33 is installed in the hoistway 4 and includes a displacement meter 5 for measuring the inter-layer displacement of each layer of the construction and a transfer means 34 for transferring the displacement measurement data by cable or wirelessly.

In comparison, the interlayer displacement distribution can be compared and evaluated more accurately. As a result, the accuracy of identifying the damaged floor is improved.

  In addition, when a typical and average interlayer displacement distribution of a building is required, a displacement meter is installed in a hoistway near the center of the building, and an interlayer displacement distribution due to the torsional vibration of the building is required. In this case, if a displacement meter is installed in a hoistway close to the periphery of a building, evaluation data can be acquired with high accuracy.
