卫星传输大震速报系统中的数据采集模块简介

卫星传输大震速报系统的软件包由数据采集和检测定位两个模块组成，数据采集模块可以实现波形数据的实时接收、保存、波形回放、人机结合提取震相参数、系统时钟的校准、对系统运行进行监视以及报警功能；检测定位模块可以实现大震速报的事件检测和参数计算。本文介绍了数据采集模块内各种功能的实现方法和可以改进的地方，供以后在似工作的人员参考。

Brief introduction of data collection module in large earthquake rapid alerting system of satellite transmission

The software package of large earthquake rapid alerting system of satellite transmission is composed of two modules: data collection and test location. Data collection module can realize real time receiving and preserving of wave data, wave shape playback, pick up phase parameter by person and computer combination, calibration of system clock, monitor of system operation and alarm function. Test location module can realize event test and parameter calculation of large earthquake rapid alerting. This paper introduces the method to realize various functions in data collection module and the improvable contents which can be as a reference for those who will do the similar things.
