Assignee:

General Electric Company - Schenectady NY

International Classification:

G08B 23/00

US Classification:

340576, 180272

Abstract:

A system is provided for monitoring an alertness of an operator of a powered system. The system includes a controller configured to initiate an alert countdown upon determining a lack of input received from the operator during an operation of the powered system. The controller is configured to communicate an alert to the operator during the alert countdown. Additionally, the controller is configured to measure a response time of the operator to the alert. A method is also provided for monitoring an alertness of an operator of a powered system.

Assignee:

General Electric Company - Schenectady NY

International Classification:

G08B 23/00

US Classification:

340576, 180272

Abstract:

A system is presented for monitoring an alertness of an operator of a powered system which operates based on a profile. The monitoring system includes a controller to initiate a query to the operator during an operation of the powered system. The query is used to prompt the operator for information related to the operation of the powered system along the profile. The controller compares a response to the query with a correct answer of the query to determine the alertness of the operator.

Abstract:

A route defect detection system for a powered system, the route defect detection system including a control system connected to the powered system for application of tractive effort, and a processor to determine an unplanned change in the application of tractive effort and/or otherwise associated with the tractive effort of the powered system. Based on the unplanned change, the processor determines a type of defect encountered along a mission route. A method and computer software code stored on a computer readable media and executable with a processor are also disclosed for a powered system to detect a defect along a mission route.

US Classification:

701 19, 249187 C, 701 20, 701 2, 701123, 60706, 60711

Abstract:

A control system for a rail vehicle system including a lead powered unit and a remote powered unit is provided. The system includes a user interface, a master isolation module and a slave controller. The user interface is disposed in the lead powered unit and is configured to receive an isolation command to turn on or off the remote powered unit. The master isolation module is configured to receive the isolation command from the user interface and to communicate an instruction based on the isolation command. The slave controller is configured to receive the instruction from the master isolation module. The slave controller causes the remote powered unit to supply tractive force to propel the rail vehicle system when the instruction directs the slave controller to turn on the remote powered unit. The slave controller causes the remote powered unit to withhold the tractive force when the instruction directs the slave controller to turn off the remote powered unit.
