[0056] The invention will be described in detail below with reference to the accompanying drawings and examples.
[0057] Such as figure 1 As shown, the present invention is an easy to expand the flexible marine seismic exploration streamer simulation system including: analog system board, indoor system, and computer;
[0058] The analog system circuit board includes: interface module, single cable analog module, and functional inspection module, which is based on a FPGA chip design in the board, and uses the interface chip on the board to achieve data transmission;
[0059] The interface module includes a plurality of full-duplex fibers or electrical interfaces, the number of interfaces is the same as the number of streamers in the stream DAQ system, and the number of transceiver drivers in the FPGA is driven. The simulation module and the two-way transmission task between the data and commands between the indoor system or function verification module, the connection of the modul...
