“…A regional network in the Vrancea region is used to detect earthquakes and issue a warning to industrial facilities in Bucharest, providing 20-25 s warning time (Wenzel et al 1999;Marmureanu et al 2011). The four strong events (M 6.9-7.7) observed during the last century all occurred in the same region at hypocentral distances of ∼160 km.…”

“…Over the last two decades, several countries have built operational earthquake early warning (EEW) systems, including Japan (Hoshiba et al, 2008), Mexico (Espinosa-Aranda et al, 1995), Romania (Mărmureanu et al, 2011), Turkey (Erdik et al, 2003), Taiwan (Hsiao et al, 2011), and China (Peng et al, 2011). Other countries, such as the United States (Böse, Allen, et al, 2013), Italy (Satriano et al, 2011), and Switzerland (Behr et al, 2015), are currently developing systems or evaluating algorithms in their seismic real-time networks.…”

“…As the main 5 equipment for seismic exploration, the acquisition station is the core of resource exploration and energy acquisition, with the collection of raw data with high signal-to-noise ratio (SNR), resolution and fidelity being the most crucial aspect [1] [7] . A distributed wireless microseismic acquisition station pre-processes and amplifies the analog signals collected by the detector and converts them into digital signals with strong anti-interference ability.…”

Abstract. In recent years, owing to the shortage of oil and gas resources and increased difficulty in mining, traditional (wired) microseismic monitoring equipment has been unable to meet the needs of energy exploitation. Therefore, it is necessary to develop new high-precision seismic exploration and data acquisition systems. In this study, we combined advance acquisition 10 systems with wireless technology to develop a new wireless microseismic acquisition system. The hardware circuit of the acquisition system mainly included a data acquisition board and a main control board. High-precision analog-to-digital conversion and digital filtering technologies were used to provide data with high signal-to-noise ratios, resolution, and fidelity to the acquisition stations. Key technologies were integrated into the ARM of the main control board. Reliable GPS technology was employed to realize synchronous acquisitions among various acquisition stations, and WIFI technology was used to 15 achieve wireless data communication between acquisition stations and the central station, thus improving the data transmission speed and accuracy. After conducting a series of evaluation tests, it was found that the system was stable, convenient to use, and had high data accuracy, therefore providing significant support for the solution to problems encountered in current oil and gas exploration processes, such as the complicated environment and inconvenient construction. 20
