Here, a case will be described in which the initial setting information database DB1 is constructed in advance in order to avoid complications.

  In step 100 of the figure, the horizontal displacement amount, the vertical displacement amount, and the temperature measurement information from the transmission device 60 and the reception of the displacement measurement position specifying information and the temperature measurement position specifying information associated therewith are waited for, In the next step 102, all the initial measurement values are read from the initial setting information database DB1, and the horizontal displacement measurement transmission device 14 or the vertical displacement measurement transmission device 16 is provided based on the read initial measurement values and the received information. The horizontal deviation amount, device height fluctuation amount, and flange inclination in the seismic isolation device 12 are calculated.

It is determined whether or not the seismic isolation device 12 to be present is present. If a negative determination is made, the process proceeds to step 112 described later, whereas if an affirmative determination is performed, the process proceeds to step 110.

Finally, control is performed so that the time interval set by the processing of step 118 is reached. Further, in the seismic isolation device monitoring processing program according to the present embodiment, the date and time when monitoring of the seismic isolation device 12 to be monitored is terminated is predetermined as the predetermined end timing applied in the processing of step 120. However, the present invention is not limited to this, for example, the timing at which an instruction input for instructing the end of the seismic isolation device monitoring processing program is made via the keyboard 20E or the like, or secondary storage It goes without saying that other timings such as a timing when the remaining storage capacity of the unit 20D becomes a predetermined amount or less can be applied.

  As described above in detail, in this embodiment, the horizontal displacement amount (horizontal deviation amount in this embodiment), vertical displacement amount (in this embodiment, the device height fluctuation amount and the flange) (Slope) and temperature are stored continuously in chronological order at predetermined time intervals, and the state of deformation of the seismic isolation device over time based on the horizontal displacement, vertical displacement, and temperature Since the deformation state information indicating is displayed, it is possible to grasp the occurrence of an unexpected abnormality of the seismic isolation device with high accuracy.

  Further, in the present embodiment, control is performed so that a warning is issued when the seismic isolation device having a degree of deformation indicated by the deformation state information is equal to or greater than a predetermined degree. It is possible to easily grasp that the seismic device has deformed abnormally.

  Furthermore, in the present embodiment, the horizontal displacement amount, the vertical displacement amount, which are measured for the seismic isolation device whose degree of deformation per predetermined time indicated by the deformation state information is smaller than a predetermined degree, Since the temperature storage frequency is controlled to be lower than the storage frequency for the other seismic isolation devices, the storage capacity for storing the measurement information can be saved.
