METHOD AND DEVICE FOR REMOTE TRANSMISSION OF SIGNALS AND APPLICATION TO THE DETECTION AND/OR MEASURING THE FUEL GAS CONTENT IN AN ATMOSPHERE

摘要

The invention relates to a method and apparatus for transmitting signals transmitted by at least one energy-assisted transducer and connected to a teletransmission line and consists in that the energy required for the power supply of the transducer is transmitted by line in the form of an alternating current of intensity in a substantially constant manner, said line fulfilling the triple function of supplying the energy of the signal transducer from it. The device mainly comprises at least one bifillary transmission line, fed into the alternating current, fed into the alternating current and containing a transformer at each of its extremities. It further comprises at least one energy-assisted transducer of each transmission line, as well as the central control unit and computerized processing, at least one demodulator modulator, connected, on the one hand, to the transformer located at one end of each transmission line and at least one demodulator modulator, connected to the transducer at the other end of each transmission line, each transducer being connected to each demodulator modulator connected to the other end of each transmission line.
