摘要：<p>The method transmits two state information down a transmission line with very high reliability, typically for use on railways and other systems where very high reliability is required. The transmitting and receiving equipments operate in a handshaking manner to ensure failsafe operation. A signal generator (1) which responds to some condition to be reported, is linked to a remote receiver via a transmission line (6). The receiver supplies the transmitter with a phase, frequency or pattern encoded auxiliary signal over an auxiliary transmission line (11), and this is used at the transmitter (1) to define the precise pattern of the transmitted signal, typically via a frequency divider (10) and electro optical link (3').</p>
