Title: Device for data transmission and track guidance of vehicles
Inventor: GOETTING JUN HANS-HEINRICH DIP
IPC: H04B5/00
Filed: 1989-05-22
Abstract: In a data transmission between track-guided vehicle and devices on the installation side, conductor loops in the track are often used, as for track guidance. Adjacent conductor loops interfere with each other by means of coupling. For separated conductor loops, separated grooves must also be provided in the track. The invention makes possible the laying of data tranmission loops and track-guidance conductors or loops in one groove without interference. The problem is solved by means of the symmetrical construction of the loops. Interfering fields are thus compensated by means of equally large or oppositely-directed fields. Ribbon-cable conductors are advantageously used in this case. Equipment of installation for operating vehicles.
