Microprocessor based electro-pneumatic locomotive brake control and train monitoring system
First Claim
1. For use in a railroad train comprising a plurality of interconnected vehicles including at least one locomotive and a plurality of cars, the improvement comprising an apparatus for electronically controlling pneumatically actuated train brakes, the apparatus comprising in combination:
- a digital control device on each car to electrically control and monitor electro-pneumatic brake control valve functions on said car;
a master controller on a locomotive for instructing the control devices on each car;
a Neuron chip on each car in a LonWorks network between the control device on each car and master controller for exchanging information and instructions; and
power source means for providing power to the control device on each car and master controller.

Abstract
A computerized electro-pneumatic braking system that includes a train monitoring system. Preferably, the braking system control device is installed on all vehicles on the train. When braking is initiated, the system applies the brakes instantaneously and simultaneously to all the vehicles on the train, bringing the train to a stop quickly. Sensors on the system'"'"'s control device also monitor operating conditions of each vehicle and report the results to the master controller.
