| titleOfInvention | Real time seismic telemetry system |
| abstract | REAL TIME SEISMIC TELEMETRY SYSTEM ABSTRACT OF THE INVENTION A real time seismic telemetry system includes a central station (10) for communication with a plurality of remote data acquisition units (14). The command station (10) has a command unit (34) for controlling the operation of a transmitter (40) for providing instructions to the data acquisition units (14). The data acquisition units (14) receive the data on a receiver (80) and process the data in a logic control circuit (88). Remote data is picked up with a hydrophone (30) and coverted to digital data for transmission through a transmitter (78) which is tuned to a discrete channel for each data acquisition unit (14). The command station (10) has a PCM receiver (62) tuned to each of the channels for demodulating the data stream therefrom. A digital receiver (66) is provided for synchronizing and processing the data. The digital receiver (66) synchronizes both to the bat rate and to the beginning and ending of the digital word such that data contained in the digital word can be multiplexed onto a data bus (68). The data bus (68) is controlled by an external storage/control (70) for storage of the data from all of the digital receivers (66) for all of the discrete channels. |
