一、概述为了改变我国地震观测设备的落后面貌,为了满足地震资料分析和地震预报对观测系统宽频带、大动态、数字化的要求,以及便于地震资料的国际交换,研制了基准台现代化数字测震系统,简称 BSO。在研制过程中,系统的计算机部份进行了三次修改,从采用小型机到瀲计算机,最后定型为单板机,反映了近年来由于微电子技术的革命推动了计算机技术的飞 I. Overview In order to change the backwardness of China’s seismic observation equipment, in order to meet the requirements of wideband, large dynamic and digital observation system for seismic data analysis and earthquake prediction, and to facilitate the international exchange of seismic data, a modern digital seismic survey System, referred to as BSO. In the development process, the computer part of the system was revised three times, from the use of minicomputers to the computer, the final stereotypes for the single-board machine, reflecting the recent years as a result of the revolution in microelectronics technology to promote computer technology to fly
