摘要
INOVA公司的iX1数字系统是一个完全数字化的地震勘探采集系统,这就意味着在系统中没有模拟组件,因而也就不会出现模拟设备故障或模拟电气指标的变化,这在应用中会极大地简化系统测试过程.但测试项目的变化也会给常年使用模拟系统的技术人员带来困惑,譬如,哪些模拟测试项目可以用做数字系统的评价?哪些项目在数字系统没有意义?本文通过对INOVA的AccuSeis SL11单分量数字检波器工作原理介绍,进而说明数字系统的测试指标及其测试原理.
The iX1 digital system is a full digitalized seismic exploration acquisition system that means there is no analog component,as well as no appearance of any analog device failures and electrical parameters change.This will greatly simplify the system test progress in its application.But this change brings confusion to the technicians who have been using the analog system all year round.For example,which analog test items can be used to evaluate digital systems?What items do not make sense in digital systems?Based on the working principle of AccuSeis SL11 1C digital geophone,this article introduces the testing index and principle of digital system.
