Description

地震预测仪
本实用新型涉及一种预报测定地震的地震预测仪。
地震是一种对国民经济和人民生命财产有重大危害的自然现象，人们一直希望能够了解地震产生的原因，认识这种地震的活动规律，实现对强地震发生时间、地点和量级的准确预报，以便尽可能避免或减少强地震造成的损失。人们对地震的产生原因和预测地震的发生时间、地点及震级已作了不少研究报导，从对于预测地震发生研究结果告诉人们，在地震发生的前期往往会产生异常的电磁辐射现象。虽然，当今常有地震发生的国家已研制出了多种地震观测仪器，在对预测地震发生及预报地震方面取得了积极的作用，可至今没有一种基于震前异常电磁辐射的探测，能准确预测地震震源位置和震源覆盖范围及估算地震发生时刻、震源深度和震级的仪器。
本实用新型的目的针对现有技术存在的不足而设计一种能通过探测地震前异常电磁辐射信号、准确预报测定地震的震源位置和震源的覆盖范围及估算出地震发生时间、震源深度和震级的地震预测仪。
本实用新型的目的是这样实现的：一种地震预测仪，其特征在于包括由三维宽频带感应探头、前置放大器、传输屏蔽电缆、主机及慢速磁带机组成，其主机内配有50Hz陷波器、A/D转换器、GPS接收器、自校数字钟和信号分析器，及设有键盘和鼠标接口，感应探头与前置放大器相连接，前置放大器由传输屏蔽电缆与主机的50Hz陷波器连接，陷波器与A/D转换器相连接，A/D转换器与信号分析器相连接，主机的GPS接收器分别与信号分析器、自校数字钟相连接，自校数字钟与A/D转换器、慢速磁带机相连接。其工作原理为：由地表面上放置的一组三维宽频带高灵敏感应探头，探测地表空间中微弱的电磁信号，对三个方向通道上的分量信号分别产生放大的输出电压信号。由于震前电磁信号可能极弱，要通过高灵敏度、低噪声、低温漂的前置放大器，将探头产生的输出信号再次放大。为消除50Hz市电干扰，通过一个频响为50Hz的陷波器，除去放大信号中的市电干扰成分，得到所要探测的三个分量的电磁信号。与此同时，通过GPS接收器接收标准的秒信号，送入自校数字钟，从数字得到标准的时标信号。三分量电磁信号与标准的时标信号一方面作为模拟信号可直接输入慢速磁带机内由磁带记录下来，以便查找、检验；另一方面要直接输入A/D转换器内，将三分量模拟信号和时标信号换成数字信号，送入信号分析器，GPS接收器接收的观测点定位数据也同时送入信号分析器。信号分析器能对电磁信号加以识别，选出电磁辐射类型的信号，并分别对三分量所选信号进行分析处理，预报测定地震的震源位置和震源覆盖范围，估算出地震发生时间、震源深度和震级。
本实用新型结构简单、安装方便、操作容易，能准确的测定地震前异常电磁辐射信号，对预报地震发生具有相对的正确性，值得推广应用。
