The buildings 11, 14, 17, and 19 are applicable as long as there is at least one building in one area.

  Then, vibration data detected based on the earthquake that occurred in the area where the earthquake detector 1 is installed is transmitted to the vibration data analysis device 4 via the Internet 3. The Japan Meteorological Agency 2 transmits an earthquake early warning including vibration data to the vibration data analysis device 4 via the Internet 3 based on an earthquake that has occurred in an area (not shown) where a seismometer (not shown) under the jurisdiction of the Meteorological Agency 2 is installed.

  The storage unit 5 of the vibration data analysis device 4 stores geological data 6 and building data 7. The geological data 6 is data defining a relationship between an earthquake occurrence location and a vibration force with respect to a plurality of regions 10 and 16 which are controlled by the vibration data analysis device 4. The building data 7 is data that defines the structure, height, age, etc. of the building.

  The earthquake data creating means 8 of the vibration data analysis device 4 includes the earthquake data and geological data 6 included in the vibration data transmitted from the earthquake detector 1 via the Internet 3 or the emergency earthquake flash report transmitted from the Meteorological Agency 2 via the Internet 3. Based on the above, predicted earthquake data such as a hypocenter direction, a predicted seismic intensity, and a predicted period corresponding to each of the regions 10 and 16 under the jurisdiction are created, and the created predicted earthquake data is output to the control data creating means 9 of the vibration data analyzer 4. I do.

  The control data creation means 9 is based on the predicted earthquake data calculated by the earthquake data creation means 8 and the building data 7, and the active systems installed in each of the plurality of buildings 11, 14, 17, 19 in the regions 10, 16. The control data corresponding to each of the vibration control devices 12, 13, 15, 18, 20, 21 is created, and the created control data is transmitted to the active vibration control devices 12, 13, 15, 18, 18, 20, 21 via the corresponding Internet.

To work.

  FIG. 2 illustrates an active damping device 29 corresponding to the active damping devices 12, 13, 15, 18, 20, 21 shown in FIG. In FIG. 2, the inside of an oil damper 30 of the active vibration damping device 29 is divided into a first inner chamber 32 and a second inner chamber 33 by a piston 31, and hydraulic oil is provided in the first inner chamber 32 and the second inner chamber 33. When the piston 31 moves in the direction of decreasing the volume of the first inner chamber 32 with the piston rod 36, the hydraulic oil 34 flows from the bypass 37 via the electromagnetic orifice portion 38 and the bypass 39 to reduce the volume. When the piston 31 moves in the direction of decreasing the volume of the second inner chamber 33 by the piston rod 36 into the increasing second inner chamber 33, the hydraulic oil 35 passes from the bypass 39 through the electromagnetic orifice portion 38 and the bypass 37. Then, it flows into the first inner chamber 32 whose volume increases. The mounting portion 40 of the oil damper 30 is mounted on one of the portions to be damped such as columns and beams in the buildings 11, 14, 17, 19 shown in FIG. 1, and the mounting portion 41 of the piston rod 36 is shown in FIG. It is attached to the other of the portions to be damped such as columns and beams in the buildings 11, 14, 17, and 19.

  Then, the electromagnetic orifice section 38 controls the passage cross section of the orifice (not shown) of the electromagnetic orifice section 38 which relays the bypasses 37 and 39 based on the control data output from the control data creating means 9 of the vibration data analyzer 4. I do. By controlling the passage cross section of the orifice of the electromagnetic orifice portion 38, when the passage cross section of the orifice increases, the flow rate of the hydraulic oil 34, 35 flowing between the bypasses 37, 39 increases, and when the passage cross section of the orifice decreases, the bypass 37, 37 decreases. The flow rates of the hydraulic oils 34 and 35 flowing between 39 decrease. Therefore, the flow rate of the hydraulic oil between the bypasses 37 and 39 is adjusted based on the control data input by the electromagnetic orifice section 38, and the active vibration damping device 29 suppresses the shaking of the vibration control target portion of the building. That is, the active vibration damping device 29 includes the electromagnetic orifice portion 38 that controls the flow of the hydraulic oil 34, 35 between the first inner chamber 32 and the second inner chamber 33 separated by the piston 31 inside the oil damper 30. Therefore, the electromagnetic orifice unit 38 is controlled by control data consisting of an electric signal transmitted from the control data creating means 9 to the active vibration damping device 29 via the Internet 3, and the active vibration damping device 29 Part shaking can be suppressed.

  The operation of the building vibration suppression system according to the embodiment of the present invention will be described with reference to FIG. In FIG. 3, when an earthquake occurs in step 301, a seismometer (not shown) managed by the Meteorological Agency 2 transmits observation data to the Meteorological Agency 2 in step 302. In step 303, the Meteorological Agency 2 transmits an emergency earthquake alert including the earthquake data to the vibration data analyzer 4 via the Internet 3, and proceeds to step 305. Further, in step 304, the earthquake detector 1 detects the earthquake that occurred in step 301, and the detected earthquake data is transmitted to the vibration data analyzer 4 via the Internet 3 by the earthquake detector 1, and the process proceeds to step 305. In step 305, the earthquake data creating means 8 of the vibration data analysis device 4 creates predicted earthquake data such as an epicenter direction, a predicted seismic intensity, and a predicted period for each of the regions 10 and 16 based on the earthquake early warning or the vibration data and the geological data 6. I do.

  Then, in step 306, the control data creation means 9 of the vibration data analysis device 4 uses the vibration data and the building data 7 to construct the buildings 11, 14, 17, 19 and the active vibration suppression devices 12, 13, The control data for each of 15, 18, 20, and 21 is obtained, and the obtained control data is transmitted to each of the active vibration dampers 12, 13, 15, 18, 20, and 21 via the Internet 3. In step 307, the active vibration damping devices 12, 13, 15, 18, 20, 21 individually operate based on the control data, and the active vibration damping devices 12, 13, 15, 18, 20, 21 are moved to the buildings 11, 14, 17, respectively. , 19 are suppressed.

  As described above, the vibration suppression system for a building according to the embodiment of the present invention provides, when an earthquake occurs, the predicted earthquake data and the active vibration damping device for each of the areas 10 and 16 controlled by the vibration data analysis device 4.
