Abstract
A consist power monitor provides information to the engineer of a multiple unit consist on the ability of each locomotive to provide traction power and dynamic braking. The consist power monitor is a microprocessor based device which communicates with other locomotive consist power monitors, either through the MU cable or over a wireless link, to display consist status to the engineer. Where the communication is through the MU cable, the communications link is provided by a high frequency carrier superimposed on an existing MU cable wire. No modification is required to the MU cable allowing for easy retrofit of existing locomotives. The alternative wireless communication is accomplished by means of a low power, spread spectrum data link now being incorporated into new locomotives. Information exchanged among the consist power monitors pertains to loading and dynamic brake conditions of the locomotives in the consist. Locomotive consist information is presented continuously.
