Seismic Network In Real Time Automatic Processing Method And System Implementation

The thesis makes a lot of researches about the identification of earthquake suitable for the area, earthquake location method and early to calculate approximate wave magnitude by the analysis of Daqing Digital Seismic Network seismic records.it makes full use of the methods to develop a series of data processing system that is suitable for the Daqing Digital Seismic Network,which can make the network gives reasonable and reliable seismic parameters in second-class time after the earthquake (Network to receive the three stations after the first break)。so as to enhance the seismic velocity at the time, for the Daqing region's economic construction and people's lives and security escort for the Government to provide timely and accurate decision-making information to reduce the earthquake and the resulting secondary disasters.Phase identification technology mainly uses the traditional analysis of the length of time window, while adding digital filter technology to remove interference with information in advance, and then use the length of time window for automatic analysis phase.Earthquake location method is to use of the grid technology, adopts the advanced double difference earthquake location method and makes use of the coming of the three of the first break Taiwan to complete the seismic wave positioning.to optimize the use of grid search saves a plenty of time in the earthquake location.The calculation of magnitude earthquake cases aims mainly at the summary and the beginning of fitting to be used to calculate maximum amplitude wave magnitude formula for calculating the magnitude.At the same time, with the help of Windons system, Using Visual C ++ language to develop automated real-time seismic processing system gets the rapid result of seismic location,which greatly increased the speed reporting when it happens.
