摘　　要：介绍了一种完全自主研发的新型数字地震记录仪,系统采用双CPU结构、GPS授时同步与高精度恒温晶振相结合的时钟机制、新型24位A/D、完全超大容量电子固态存储以及内建自测试(BIST)等新技术,非常适合于天然地震的野外流动观测,也可应用在人工源反射、折射地震勘探等其他领域,是一种数据可靠、使用方便、具有较高性能价格比的宽频带地震数据采集系统.As a new generation digitizer, BSR-2 broad band seismic recorder adopt advanced computer and electronics technologies such as the double CPU structure, the precise timing service combined of GPS receiver and OCXO digital clock, the 24-bit Delta-Sigma A/D converters, the mass on-site data storage system, the build-in self-test method and so on. The ideal acquisition device can be widely used in the observation of ground motions caused by local and distant earthquakes, artificial explosions, vibrators and other natural and human induced activities. It is a reliable and convenient seismic data acquisition system with a high ratio of property to price.
