Locomotive control system having variable energy management

Abstract

A control system for a train is disclosed. The system may include an input / output (I / O) module configured to receive one or more inputs indicative of operating parameters of the train, a plurality of energy management modules configured to generate control signals associated with components of the train based on the operating parameters of the train, an interface gateway in communication with each of the plurality of energy management modules, and a control module in communication with the I / O module and the interface gateway. The control module may be configured to select one of the energy management modules based on the one or more inputs received by the I / O module, receive control signals via the interface gateway from the selected one of the energy management modules, and send command signals to components of the train based on the control signals from the selected one of the energy management modules.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a control system, and more particularly, to a locomotive control system having variable energy management.BACKGROUND[0002]Machines, such as passenger vehicles, trains, tractor trailers, airplanes, marine vessels, construction equipment, etc., are used to perform a number of different tasks under varying operating conditions. To achieve optimum performance under a given set of operating conditions, operational control strategies for such machines may be adjusted as operating conditions change. For instance, each type of machine may be controlled differently based on changes in ambient temperature, humidity, load (e.g., based on cargo weight, uphill / downhill travel, headwinds, etc.), altitude, and / or other operating parameters. Other control variables may include regulatory restrictions, such as speed limits, sound level limits, emission constituent limits, etc. Because machine control strategies can be complex and involve numerou...

AI Technical Summary

Benefits of technology

The present patent is directed to a control system for a train that can manage energy usage based on operating parameters of the train. The system includes an input / output module, multiple energy management modules, an interface gateway, and a control module. The control module can select the energy management modules based on the operating parameters, receive control signals from the selected energy management modules, and send command signals to components of the train. The technology can help improve efficiency and safety of the train by optimizing energy usage and controlling components based on real-time information.

Problems solved by technology

Because machine control strategies can be complex and involve numerous variables, automatic control systems have been implemented that receive predetermined and sensory inputs and generate tailored control signals based on the inputs.

Because trains are typically very heavy and can include, in some instances, hundreds of rolling stock assets that span lengths of track over a mile long, energy management strategies for trains can be very complex.

While the system of the '143 patent may allow an energy management system to be received from a client module, it may not be optimum.

In particular, the ability of the system of the '143 patent to conserve fuel may be limited by the scope of control or the particular control strategy associated with the energy management application of the client module.

That is, the energy management application of the client device may not be optimum under all circumstances and for performing all types of tasks required of the train.
