Abstract
A method and an apparatus for an on-board train control device are provided, and are based on converting speed codes received from wayside cab-signaling devices into movement authority limits. The device determines the train location independent of the wayside train detection system, and generates and enforces stopping profiles based on said movement authority limits.
Claims31
An on-board train control system that interfaces with wayside cab-signaling installation, comprising:
- an on-board location determination subsystem,
- on-board means for receiving, and decoding cab-signaling speed codes,
- on-board means for converting said cab-signaling speed codes received from cab-signaling installation to movement authority limits, and
- on-board means for generating a stopping profile to enforce a movement authority limit.
An on-board train control system that interfaces with wayside cab-signaling installation, comprising:
- an onboard vital module to determine the location of the train,
- an onboard vital module that decodes a speed code received from a wayside device, and converts it into a corresponding movement authority limit, and
- an onboard vital module that generates and enforces a stopping profile based on said movement authority limit.
A train control system, wherein a vital on-board controller interfaces with a wayside cab-signaling installation, and wherein said on-board controller determines the location of the train, receives discrete speed codes from wayside cab-signaling devices, generates movement authority limits that correspond to the speed codes received from cab-signaling devices, and generates and enforces stopping profiles based on said movement authority limits.
A train control system, wherein a vital on-board controller interfaces with a wayside cab-signaling installation, and wherein said vital on-board controller comprises:
- an on-board location determination subsystem,
- an on-board interface device to receive speed codes from the cab-signaling installation,
- an on-board vital processor with a computer-readable medium encoded with a control logic and a vital data base to control the movement of the train, a control logic segment that converts a received cab-signaling speed code into a movement authority limit, and
- a control logic segment that generates and enforces stopping profiles that are based on movement authority limits.
A method for an on-board controller that interfaces with a wayside cab-signaling installation comprising the on-board steps of:
- determining the location of the train,
- converting speed codes received from cab-signaling wayside devices into movement authority limits, and
- generating and enforcing stopping profiles based on said movement authority limits.
An on-board train controller that interfaces with wayside cab-signaling equipment, and wherein the on-board controller comprises:
- an on-board location determination subsystem,
- an on-board interface device that receives speed codes from said cab-signaling wayside equipment,
- an on-board processor with a computer-readable medium encoded with a control logic to control the movement of the train,
- a control logic segment that converts speed codes received from cab-signaling wayside equipment into movement authority limits, and
- a control logic segment that generates and enforces stopping profiles that are based on said movement authority limits
A train control system that integrates an on-board communication based train control device with wayside cab-signaling equipment, wherein the onboard communication based train control device comprises:
- onboard transponder based location determination subsystem,
- an onboard interface device that receives speed codes from said wayside cab-signaling equipment,
- onboard means for converting said speed codes to movement authority limits, and
- onboard means for generating and enforcing stopping profiles that correspond to said movement authority limits.
