Method for synchronising, control system for synchronising secondary units and synchronisable secondary units

摘要

The method involves managing time synchronization of two supporting units. The supporting units and the master unit are connected by two signals. A signal sent by the master unit to all supporting units returns to the master unit. In each supporting units two independent counters are provided, receiving a reference signal which the master unit sends. The first timer counts the time since the receipt of the reference signal over the first signal and the second counter the time since the receipt of the reference signal over the second signal. The counts are selected, as soon as the sum of the counts reaches the master unit communicated signal turn-around time. An independent claim is included for a control system.
