Modular device for the reception, the acquisition and the transmission, to a central control and recording unit, of signals picked up by a very large number of seismic acoustic receivers distributed along a streamer of great length under water in operation. The receivers in each one of the sections (Tk) of the streamer are arranged in several groups and the receivers (H1 to Hp) of a same group are connected with an acquisition unit (U1 to Um) located close to them. All the units of each section are connected through digitized command and data transmission lines (LOC,BD) with a common memory and a transmission management unit in an interconnection box (Bk) at one end of the streamer section. Transferring a great part of the electronic equipment into the streamer sections is very favorable for the balancing of the streamer in the water, for obtaining a good signal to noise ratio and it facilitates the development and the exploitation of the material.
A modular system for transmitting signals received by seismic sensors in an immersed seismic streamer to a central control and recording station on a ship towing the seismic streamer with the streamer comprising a sheath made by a series of connected sections interconnected by interconnection boxes with the sensors being distributed along a length of a plurality of the sections, the modular system including an electronic device comprising:
