Abstract

Installation of multiplexed transmission of seismic signals, and more particularly installation for transmission to a central unit of registration of the electrical signals of different sensors or groups of sensors of seismological vibrations, characterized by comprising a single transmission line arranged in the area of the sensors between the central recording unit and a pulse generator mounted at the end of the line, each sensor being associated with the line by means of a connection assembly comprising a multiplexing element comprising electronic gates to establish communication between the sensor and the line, and an element to command the opening of said doors, in response to the specific reception of the impulses, in such a way that the signals arrive at the central recording unit according to a multiplexing sequence corresponding to the frequency of command pulses.
