Earthquake early warning monitor location change identification method based on magnetic field sensor

Abstract

The invention relates to the field of earthquake early warnings, in particular to an earthquake early warning monitor location change identification method based on a magnetic field sensor. The problems of misinformation of an early warning system, the large earthquake early warning parameter deviation and the like caused by the fact that an earthquake early warning monitor is moved are solved. The magnetic field sensor for detecting the earth magnetic field strength of the position where the earthquake early warning monitor is located is allocated in the earthquake early warning monitor. The earthquake early warning monitor location change identification method includes the start judging step, the parameter setting step, the earth magnetic field monitoring step, the judging step and the executing step. A system comprises a start judging module, a parameter setting module, an earth magnetic field monitoring module, a judging module and an executing module. The judging module and the executing module can be arranged on the earthquake early warning monitor or an early warning center. The earthquake early warning monitor location change identification method is concise, convenient to implement, suitable for earthquake early warning monitors without GPS location devices, and favorable for improving the reliability of the earthquake early warning system.

Description

technical field [0001] The invention relates to the field of earthquake early warning, in particular to a magnetic field sensor-based method for identifying the position change of an earthquake early warning and monitoring instrument, which is used to monitor whether the earthquake early warning and monitoring instrument is moved. Background technique [0002] In earthquake early warning, earthquake early warning and monitoring instruments are required to accurately locate the epicenter, and the location of earthquake early warning and monitoring instruments is the basis for determining the location of the epicenter. important. For this reason, after the earthquake early warning and monitoring instrument is installed, it is necessary to bind the longitude and latitude of the instrument's location with the instrument's ID number. The position of the instrument can be determined by a GPS positioning device, but this method requires each instrument to be equipped with a GPS mo...
