URBAN RAIL TRAIN AND TRAIN HARD-WIRED SIGNAL TRANSMISSION CIRCUIT THEREFOR, AND TAIL CLOSED LOOP CIRCUIT FOR USE IN TRAIN HARD-WIRED SIGNAL SCENARIO

摘要

An urban rail train and a train hard-wired signal transmission circuit therefor, and a tail closed loop circuit for use in a train hard-wired signal scenario. The train hard-wired signal transmission circuit comprises: a first storage battery (10); a first connector (20); a second connector (30); N key signal switching units; a first electrical signal receiving component (40); and a second electrical signal receiving component (50). A first end of the first connector (20) is connected to the first storage battery (10), and a second end and the first end of the first connector (20) are connected to each other. The N key signal switching units are connected in series between the second end of the first connector (20) and a second end of the second connector (30), where N is a positive integer. A third end of the second connector (30) is respectively connected to the first electrical signal receiving component (40) and the second electrical signal receiving component (50). The second end and the third end of the second connector (30) are connected to each other.
