Anti-collision control system for trackless vehicles - has stationary transmitter and guide AC cable

摘要

In addition to the alternating current, a pulsed item of information is fed into the cable by a stationary transmitter at fixed timed intervals. This information then is received by all vehicles. Each of the vehicles has a receiving device preferably arranged on its bottom and receiving the pulse originating from the cable and containing the information. When they receive pulsed information from the cable, the vehicles transmit, in turn, pulsed information in the form of a burst at the tail of the vehicle Cable (K).
