Remote control system using TDM transmission stations - transmits orders on sequential programme and on detection of modification, changes to other order at end of cycle

摘要

The TDM transmission system uses a number of autonomous transmission stations, each with a transmitter and a receiver, for transmitting orders to receivers associated with remotely-controlled movable objects, e.g. trains in an automatic train system. Each staion transmits orders within a transmission cycle modified in according with previous orders. The transmission point for each station within the sequential transmission programme is determined by a received identification code with the message transmitted to a station for modifying the orders immediately after the end of the transmission cycle for the preceding station in the sequence.
