From the point of view of, the monitoring to shock isolating pedestal health status is particularly important.
In prior art, the monitoring to the stressing conditions of shock isolating pedestal relies primarily on pressure sensitive unit, and sensing unit
Recording the data message after pressure needs to derive by lead it is necessary to do micropore on bearing for drawing wire, and then
The mechanical property leading to bearing overall is affected, because the bearing of bridge needs to bear huge load, even small
Hole will also result in huge potential safety hazard；In addition, the replacing of sensing unit is also front holder technical field face one
A difficult problem, because sensing unit is usual and support body is affixed or imbed the reasons such as bearing inside, to carry out more to sensing unit
Change, then need to change whole bearing, high cost and complex operation.
