Method for the testing and monitoring of brakes in rail vehicles
First Claim
1. A method for the testing and monitoring of brakes of railroad vehicles individually and coupled together in a train comprising the steps of;
- placing sensors at predetermined points in a railroad vehicle braking system to obtain information as to the status of a braking system function at each said point, said information being generated as information signals by said sensors;
storing said information signals for each bogie of the railroad vehicle in a bogie processor mounted in the railroad vehicle;
reading said information signals from said bogie processors and storing said information signals related to a predetermined operational period in a car processor mounted in the railroad vehicle;
selectively reading said information signals stored in said car processor, performing diagnostic tests on said information signals to generate test results and storing said test results; and
issuing status reports representing said test results, said status reports including faulty sensor reports, travel clearance reports, braking system fault diagnoses reports, orders and instructions for fault elimination and advisories for maintenance operations that are due.

Abstract
A method for performing operationally prescribed brake trials before the departure of a railway train, utilizes an indicating and diagnostic system disposed on board the train and operated by the train driver. Sensors in the braking system of each car bogie supply information signals representing pressures, travels and forces to a bogie processor which is connected with a car processor. The car processors are connected by a continuous data bus line with a central processor. The central processor processes the operational information from the brake system according to a processing program into status reports such as general status indications, fault diagnoses and maintenance instructions. The indications and instructions are visually displayed on a monitor and a printer, and acoustically reproduced by a speech synthesizer through a loudspeaker. The car processors are programmable by means of mobile computers and interrogatable by means of pocket terminals. Stored operational data is interrogable from outside each railway car by means of a mobile personal computer at each railroad vehicle.
