Title:
単線を用い双方向通信を実行する方法及び装置
Document Type and Number:
Japanese Patent JP4573250
Kind Code:
B2
Abstract:
A communication system transfers a signal over a single signal wire (SW) between a first system (S1) and a second system (S2). The first system (S1) comprises: a first controller (C1) to supply an output signal (MO) and a switch signal (MS), and to receive an adapted input signal (MIA). The output signal (MO), the switch signal (MS), the adapted input signal (MIA), and the first controller (C1) are referenced to a first ground potential (G1). A first galvanic separating unit (U 1) receives the output signal (MO), the first ground potential (G1), and a second ground potential (G2) to supply to the single signal wire (SW) an adapted output signal (MOA) referenced to the second ground potential (G2). A second galvanic separating unit (U2) receives the first ground potential (G1), the second ground potential (G2) and at an input terminal (IT) an input signal (MI) referenced to the second ground potential (G2) to supply the adapted input signal (MIA) referenced to the first ground potential (G1). A galvanic separated switching unit (U3) receives the switch signal (MS) and the first ground potential (G1), and has a switching path (T3) arranged between the single signal wire (SW) and the input terminal (IT). The switch signal (MS) controls the switching path (T3) over an galvanic separation to selectively connect the single signal wire (SW) to the input terminal (IT). The second system (S2) comprises a second controller (C2) referenced to the second ground potential (G2) to supply the input signal (MI) to the single signal wire (SW), and for receiving the adapted output signal (MOA) from the single signal wire (SW).
