Description

A quick-reporting instrument for earthquake response monitoring

technical field

The invention relates to the technical field of earthquake damage monitoring and quick reporting instruments, in particular to an earthquake response monitoring quick reporting instrument.

Background technique

The existing instruments for recording the seismic response of large structures and slopes mainly include strong motion recorders and intensity rapid reporting instruments. Due to the small number of channels and high price, the strong motion recorder is mainly used in the official seismic network. If it is used for multi-point seismic response monitoring of structures or slopes, multiple strong motion instruments are required, resulting in high cost. Therefore, strong motion instruments are difficult to popularize in large structures and slopes. Due to its low price, the intensity rapid reporting instrument can be widely used for seismic intensity rapid reporting, but because its function is too single, it has the following disadvantages: (1) basically has no data storage function or can only store a small amount of data; (2) Each instrument can only monitor the ground motion response of one location, and the time synchronization ability between multiple instruments is poor. Therefore, it is of great practical significance to develop a multi-channel, low-cost, and rapid-reporting special earthquake monitoring and rapid-reporting instrument in combination with the actual needs of seismic response monitoring of large structures and slopes.
