| Abstract: | The technical indexes of the trigger control of the strong-motion observation system are explained.And some triggering methods used in the trigger-judgment function module of the digital strong-motion observation system and their principles are introduced,including an improved method of STA/LTA trigger which can realize continuous trigger in one motion record and an improved measure of threshold-value trigger which can restrain the influence of zero shift.Practical application indicates that the new methods are of good stability and reliability. |
