<p>The present invention pertains to a method and a system for synchronization of time slots to a part of an a.c. net frequency half cycle as well as an apparatus for performing the synchronization. More particularly it relates to a transfer method and a system for communication of pulse signals over a series cable powered by a constant current regulator for control and monitoring of lightings, lamps, sensors, detectors and other loads. It specifically relates to the technical field of control and monitoring of airfield lighting systems (TWY1, TWY2, TWY3, SB1, LO1) including sensors for Surface Movement and Guidance Control Systems (SMGCS).</p> |
