Wireless display unit for ECP transition system
First Claim
1. An interface system for interfacing a pneumatic train brake control system to a train of electrically controlled pneumatic (ECP) brake equipped cars, the interface system comprising:
- a controller monitoring pressure on a locomotive brake pipe port, the controller controlling pressure on a train brake pipe port in response to the monitored pressure on the locomotive brake pipe port, the controller providing ECP commands on an ECP trainline via a train electrical trainline terminal in response to the monitored pressure on the locomotive brake pipe port, and providing electrical power on the ECP trainline via the train electrical trainline terminal from the locomotive electrical trainline terminal;
a transceiver connected to the controller for wireless communication with the controller; and
a wireless display unit for communication via the transceiver with the controller and displaying information from the controller to the operator remote from the interface system and providing inputs from the operator to the controller,wherein communication is not established between the controller and the display unit if the controller is communicating with a device other than the display unit, and wherein once, and as long as, communication is established between the display unit and the controller, the controller rejects all request for links from devices other than the display unit to ensure secure, bidirectional communication between the display unit and the controller to enable error checking and interface heartbeat.

Abstract
The present interface system includes a controller monitoring pressure on a locomotive brake pipe port, controlling pressure on a train brake pipe port in response to the pressure on a locomotive brake pipe port, providing ECP commands on an ECP trainline via a train electrical terminal in response to the pressure on the locomotive brake pipe port, and providing electrical power on the ECP trainline via an train electrical trainline terminal from the locomotive electrical trainline terminal. A transceiver is connected to the controller for wireless communication with the controller. A wireless display unit communicates via the transceiver with the controller and displays information from the controller to the operator remote from the interface system and provides inputs from the operator to the controller. The system also includes a three position change over valve. An event recorder and a GPS system may be connected to the controller.
