Self-adaptive anti-seismic noise reduction method and device and bridge pier
The invention discloses a self-adaptive anti-seismic noise reduction method and device and a bridge pier in the technical field of bridge seismic resistance, which can automatically judge whether a seismic signal acting on entities such as the bridge pier is caused by an earthquake or not and react on the entities such as the bridge pier through vibration opposite to the phase of the seismic signal to reduce damage and loss caused by the earthquake. The method comprises the steps of collecting a first vibration signal acting on an entity; acquiring frequency spectrum information of the first vibration signal, judging whether the first vibration signal meets a set condition or not based on the frequency spectrum information, and sending a control signal when a judgment result is yes; and generating a second vibration signal opposite to the first vibration signal in phase based on the frequency spectrum information and the control signal, and enabling the second vibration signal to act on the entity.
本发明公开了桥梁抗震技术领域的一种自适应抗震降噪方法、装置及桥墩，能自动判断作用于桥墩等实体的震动信号是否由地震引起，并通过与震动信号相位相反的振动反作用于桥墩等实体，减少地震带来的破坏和损失，方法包括采集作用于实体的第一震动信号；获取所述第一震动信号的频谱信息，基于所述频谱信息，判断所述第一震动信号是否符合设定条件，并在判断结果为“是”时，发出控制信号；基于所述频谱信息和所述控制信号产生与所述第一震动信号相位相反的第二震动信号，并使所述第二震动信号作用于所述实体。
