One of the main devices in the earthquake monitoring system is the digitizer, which converts the analog signal to a digital one. We design and implement a trigger digitizer to store/transmit the seismic data. The implemented digitizer consists of several blocks, i.e., the power source, the front end circuit, analog to digital converter (ADC), GPS receiver, microcontrollers, microprocessor, and deep learning picking module. Besides, we use three finite impulse response (FIR) filters to decimate the sampling rate of the input seismic data. In addition, we utilize the CapsPhase network to pick the first arrival time of the earthquake. In this way, the digitizer is a trigger device, where an enable signal is released once the earthquake is detected to take the appropriate action.

“…The ambiguity problem of a single geophysical exploration method has always been a tricky problem in geophysical prospecting (Guo et al, 2020). Multi-method joint exploration has then become popular since it remains the advantages of different geophysical methods while reducing ambiguity problems.…”

Abstract. In this paper, we propose a new type of power station unit with wireless data transmission capability. This work breaks the limitation that conventional equipment is unable to upload data directly to central unit. Based on that, a novel distributed geophysical data acquisition architecture is also proposed. Designs that realize functions including isolated high-power output, power management and monitoring, high-speed data transmission as well as high-precision clock synchronization etc. are introduced in this article. The prototype was packaged then, and a series of evaluation experiments were implemented to verify the key parameters of the instrument. Experiment results proved that the overall design of the instrument is feasible, and the key parameters outperforms the industry leading instrument LAUL-428. Due to the wireless networking strategy, the proposed instrument further realizes remote control and real-time data playback through the host computer software, making it suitable for joint geophysical exploration as well as microseismic monitoring. In a sense, a new birth was also given to the conventional seismic and electrical acquisition stations.

Abstract. In this paper, we propose a new type of power station unit with wireless data transmission capability. This work breaks the limitation that conventional equipment is unable to upload data directly to a central unit. Based on that, a novel distributed geophysical data acquisition architecture is also proposed, enhancing the work efficiency by simplifying the system structure while maintaining core features. Designs that realise key functions including isolated high-power output, power management, wireless data transmission and high-precision clock synchronisation are introduced in this article. The prototype was packaged then, and a series of evaluation experiments were implemented to verify the key parameters of the instrument. Experiment results proved that the overall design of the instrument is feasible, and the key parameters outperform the industry leading instrument LAUL-428. Due to the wireless networking strategy, the proposed instrument further realises remote control and real-time data playback through the host computer software, making it suitable for joint geophysical exploration as well as microseismic monitoring. As for the system level, it could be customised by connecting different kinds of conventional acquisition stations for many kinds of prospecting targets.
