摘要
遥爆系统是地震勘探中重要的辅助设备,而遥爆系统的时差同步性则直接影响地震数据的采集质量。本文介绍了基于ARM9嵌入式芯片的遥爆系统同步时差测试仪器的设计,该仪器具有精确度高、功耗低、使用方便的特点,能够很好地帮助遥爆系统的同步误差的调整,对遥爆系统的检测、维修、施工前TB延迟(误差)的测试都有很好的实用价值。
Blasting system is a very important auxiliary equipment for seismic exploration, while the time error and the synchronization about the blasting system will directly impact the quality of seismic data acquisition. This article describes the design of ARM9-based embed chip synchronization tester. With fectures such as high precision, low power consumption and easy to use, this tester can be used for the system synchronization error adjustment and can be helpful for the testing, maintenance and pre-TB latency （error） test of the blasting system in field operation.
