新型多通道强震记录器研发及其应用

The development and application of the new multi-channel strong motion recorder

多通道记录器具有广泛的应用需求。为了满足用户多样化通道数量需求,我们研制了通道便于扩展的多通道记录器。该记录器采用24位AD采集器,可定制4、8、12、16、20、24通道,且通道之间完全同步采集。为了适应多通道数据记录需求,该仪器具备40GB数据存储能力。目前该仪器原型机已经进入24小时连续运行测试阶段,在测试期间完整记录到了2013年11月22日、23日吉林松原发生的三次5.0级以上地震。通过对不同触发参数、人造振动和松原地震的测试,仪器触发、记录功能准确可靠,长期连续运行稳定,具有产品化价值。

The multi-channel recorder has extensive application,such as in earthquake observation and et al. In order to meet user demand for a variety number of channels,we developed a multi-channel recorder with channels' number can be extended easily. Our new recorder adopts 24 AD. It can be customized to 4,8,12,16,20,24 channels with complete synchronization. In order to fit our new recorder to big amount data storage requirements of continous multi-channel data record for days,we equiped it with 40 GB storage space. At present,the instrument prototypes have been continuously tested for 4000 hours around,the full test is sucessful and it illustate our new recorder is long-term accurate and reliable. Moreover,during the test we record reliable 22-23 November 2013 Jilin Songyuan three times 5. 0 magnitude earthquake. Thus,we believe our new recorder is worthy of popularization.
