Abstract[English]
A detection device is disclosed for detecting a hose burst or breakage of a brake hose (1) in a pneumatic brake system, preferably in a brake system of a train, comprising: an ECU (7) comprising a brake controller, said detection device further comprising a pressure controller, control valves (5, 8, 9), and a brake pressure sensor (4), said pressure controller being configured to control said control valves for providing a brake pressure for operating a brake cylinder (2), said brake pressure sensor (4) being configured to detect the actual brake pressure lead to the brake cylinder (2), said brake controller being configured to receive the actual brake pressure, the demanded brake pressure, and the control valve outputs of the pressure controller, wherein the brake controller comprises an algorithm configured to determine a hose break.[French]
L'invention divulgue un dispositif de détection pour détecter un éclatement ou une rupture de flexible d'un flexible de frein (1) dans un système de freinage pneumatique, de préférence dans un système de freinage d'un train, comprenant : une ECU (7) comprenant un régulateur de freinage, ledit dispositif de détection comprenant en outre un régulateur de pression, des soupapes de commande (5, 8, 9) et un capteur de pression de freinage (4), ledit régulateur de pression étant conçu pour commander lesdites soupapes de commande afin de fournir une pression de freinage pour faire fonctionner un cylindre de frein (2), ledit capteur de pression de freinage (4) étant conçu pour détecter la pression de freinage réelle menée au cylindre de frein (2), ledit régulateur de freinage étant conçu pour recevoir la pression de freinage réelle, la pression de freinage demandée et les sorties de soupape de commande du régulateur de pression, le régulateur de freinage comprenant un algorithme conçu pour déterminer une rupture de flexible.
