Seismic exploration equipment has developed rapidly over the past few decades. One such piece of equipment is a centralized seismograph, which plays an important role in engineering, so improving its performance is of great scientific significance. In this research, the core part of general seismic-data acquisition devices is packaged to develop a centralized seismic-data acquisition system (named CUGB-CS48DAS) that has independent operating ability and high scalability, which can be used for seismic exploration in various engineering uses. Furthermore, by extending and modifying the acquisition circuit and corresponding software, the function of electrical method data acquisition has also been achieved. Thus, the proposed CUGB-CS48DAS makes it possible for joint exploration of seismic and electrical data in a single acquisition station, which is implicitly of great convenience in engineering prospecting as well as a solution to reduce the ambiguity problem. The low power-consumption computer of the system comprises a 24 bit Σ modulation A/D converter and 48 sampling channels with an optional sampling rate of 50 Hz to 64 kHz. With regard to the host computer, the architecture of the control software is smart, and it can integrate the multiple functions of data acquisition, preprocessing, and self-testing. To complete the networking ability and remote monitoring of this proposed system, the technology of the narrow-band internet of things (NB-IoT) was introduced and tested. Field experiments were implemented to prove that the system is stable and convenient to use, and the performance could meet the demand of high-precision joint exploration.

开发新的地震勘探集中式数据采集系统

在过去的几十年中，地震勘探设备发展迅速。集中式地震仪就是这样一种设备，它在工程中起着重要作用，因此提高其性能具有重要的科学意义。在这项研究中，将通用地震数据采集设备的核心部分包装在一起，以开发具有独立操作能力和高可扩展性的集中式地震数据采集系统（名为CUGB-CS48DAS），可用于各种工程中的地震勘探用途。此外，通过扩展和修改采集电路和相应的软件，还实现了电气方法数据采集的功能。因此，建议的CUGB-CS48DAS使得在单个采集站中联合勘探地震和电气数据成为可能，这无疑在工程勘察中提供了极大的便利，并为减少歧义问题提供了解决方案。该系统的低功耗计算机包括一个24位的计算机。Σ调制A / d转换器和48a采样与50A ???? Hz至64A ????千赫可选采样速率信道。对于主机，控制软件的体系结构很智能，可以集成数据采集，预处理和自检的多种功能。为了完成该提议系统的联网能力和远程监控，引入并测试了窄带物联网（NB-IoT）技术。通过现场实验证明该系统稳定，使用方便，性能满足高精度联合勘探的要求。
