Problems solved by technology

[0037] Therefore, it is clear that it is not profitable to develop a single electronic architecture that may simultaneously provide service brake functions, emergency brake functions, diagnostic functions and other functions, since said architecture must be fully realized according to SIL ≥ 3 levels, economical resource consumption Large, long development time

Abstract

An electronic control system of emergency and service braking (500) is described comprising an emergency brake module (501) and a service brake module (507) each including an independent and segregated electronic architecture; the service brake module (507) receives a deceleration / service braking demand signal (530) and generates a service braking pressure signal (535); the emergency brake module(501) is connected to the service brake module (507) to receive the service braking pressure signal (535), receives a signal indicative of an emergency braking demand, generates a respective intermediate braking pressure signal indicating an emergency braking (523), generates a signal corresponding to the higher value between the service braking pressure signal (535) and the intermediate braking pressure signal indicative of an emergency braking (523), which is converted to braking pressure.

Description

technical field [0001] The present invention is generally in the field of railway braking systems; in particular, the present invention relates to a system for controlling emergency braking and service braking of railway vehicles. Background technique [0002] Conventional rail braking systems perform different functions that are characterized by the state of the rail vehicle. These two main functions are called "service brake" and "emergency brake". [0003] Service braking is the condition in which a rail vehicle is decelerated during the normal phase of operational service. In this state, it must be ensured that the probability of failure of the braking performance is less than 10 -7 . This value corresponds to the Safety Integrity Level SIL2 of EN50126. [0004] Emergency braking is the state in which a train must provide braking within a stopping distance predetermined by international standards, where the probability of failure to achieve performance is usually equ...
