A real-time data gathering design is introduced in this paper, which can be used in remote sensing system as seismic data acquisition system. Generally, this kind of system is designed as distributed formation. Data acquired remotely should be transferred to a storage device or analysis center continuously. With the growing of remote sensing scale, it is more difficult to gather data real-time. Data...
Nowadays, long-distance data transmission is one of the key features for remote sensing systems such as seismic exploration. In these kinds of systems, ordinary twisted pair is more suitable than fiber optics because of working environments or limited costs. But there are two limitations as long distance and data transmission speed which are not easy to be improved in these systems. We designed and...
A reliable high density and precise streamer cable digitizer for marine seismic exploration system is introduced. In this digitizer, there are total 16 data acquisition channels each of which can be connected to hydrophones directly. Analog signals are converted into digital data by 24-bit high precise ΔΣ ACDs which is controlled by FPGA in real time. For quality control (QC) testing online, there...
In industrial control fields, surveying and control systems compose huge numbers of sensors and data transmission systems, which have a great applications in marine and land seismic exploration. The system has characteristics of large coverage area, multi-channels device and remote data transmission, which bring problems in system synchronization, data transmission and storage, system management....
