关于计算机在数字化地震前兆观测系统中的应用,首要的问题是实时地收集前兆数据。本文介绍的数字化前兆实时采集程序是在国产DJS—131计算机的支持下,在实时操作系统XRTOS的控制下,实时响应中断,实时采数;对采得的数据进行多种功能的判别、处理,并按一定格式编排,写入数字磁带,供进一步分析处理用。该程序主要应用于电信传输地震台网的前兆观测系统中。程序的设计思想及其处理方法可推广到任何其它的实时采集数据的系统中。
As for the application of computers in digital seismic precursory observation systems, the primary issue is collecting precursor data in real time. This article describes the real-time acquisition of digital precursors program is in the domestic DJS-131 computer with the support of the real-time operating system under the control of XRTOS, real-time response to interrupts, real-time acquisition of the collected data for a variety of functions of discrimination, processing, And according to a certain format, write digital tapes for further analysis and processing. This procedure is mainly used in the precursor observation system of telecommunication transmission seismograph network. Program design ideas and methods can be extended to any other real-time data acquisition system.
