Abstract
A multiplex transmission system (100) in which any (N.sub.i) of a plurality of nodes (N.sub.l -N.sub.n) connected loop-like with a signal transmission path (1a, 1b) and each respectively connected to, for controlling, one of a plurality of electrical equipments is adapted for transmitting, in a given order (i) and in accordance with a time base (1/2t.sub.1) that this node (N.sub.i) itself has, a prepared signal (A.sub.i, D) to the signal transmission path (1a, 1b) and for receiving prepared signal (A.sub.i, D; A.sub.x, D) from the signal transmission path (1a, 1b), wherein any (N.sub.i) of the nodes (N.sub.l -N.sub.n) is adapted, at a time point (r.sub.2, r.sub.3) where this node (N.sub.i) has received the prepared signal (A.sub.x, D) from any other node (N.sub.x) to have its own time base (1/2t.sub.1) synchronized with the time base (1/2t.sub.1) of the other node (N.sub.x). Any (N.sub.i) of the nodes (N.sub.l -N.sub.n) further comprises a monitoring timer (CNT.sub.2) adapted to have a monitoring time interval (t.sub.2, t.sub.i3, t.sub.i4) set thereon at a predetermined time point (59, 62, 71, 84, 88), and is adapted to rise for transmitting the prepared signal (A.sub.i, D) thereof…
