System for distributed automatic train supervision and control
First Claim
1. A system for supervision and control of a rail vehicle on a network of a plurality of sections of track having corresponding wayside locations, the system comprising:
- multi-access transport means for communicating between a first location and a plurality of subsequent locations, through substantially simultaneous transmission of a first signal from a said first location to said plurality of subsequent locations, and substantially simultaneous receipt at said first location of a plurality of subsequent signals from said plurality of subsequent locations, respectively;
a plurality of wayside controller units, one each respectively located at the corresponding wayside locations, and each electrically coupled to said multi-access transport means, thereby to transmit said first signal and to receive said plurality of subsequent signals between each of said plurality of wayside controller units, for local configuration and reporting and control of said plurality of wayside controller units; and
operator interface means electrically coupled to said multi-access transport means, for interacting by an operator with said plurality of wayside controller units.

Abstract
A system for supervising and controlling the movement of a railway vehicle is provided, wherein a plurality of wayside controller units are each distributed to a plurality of wayside controller locations by a multi-access carrier, such as a fiber LAN or IEEE 802.3 Ethernet, for instance, such that supervisory and control operations may be communicated between each of the wayside controller units with a multi-access protocol on the multi-access carrier. The present invention replaces the use of a serial-link protocol for point-to-point communication with a multi-access protocol on a multi-access carrier. In a preferred embodiment, a computer-based control system may be connected through the multi-access carrier, so that communication is achieved solely with multi-access protocols. Related art Centralized traffic control (CTC) functions may be eliminated from a global services (GS) block of the central office (CO) and implemented as Distributed Traffic Control functions that are distributed to the wayside controller units.

6. A system for distributed automatic supervision and control of a railway vehicle among a plurality of wayside locations, wherein the system comprises:
-
a plurality of wayside controller units, each located at one of a plurality of wayside locations, respectively, thereby to transmit a first generated signal and to receive a plurality of subsequent signals related to supervision and control of each one of said plurality of wayside controller units; multi-access transport means for communicating between each one of said plurality of said wayside controller units, through substantially simultaneous transmission of said first generated signal and said plurality of subsequent signals,wherein each of said plurality of said wayside controller units is electrically coupled to said multi-access transport means; and operator interface means electrically coupled to said multi-access transport means, for interacting by an operator with said plurality of wayside controller units. - View Dependent Claims (7, 8, 9, 10)
