Abstract:
(EN) A test apparatus (100) for measuring the impedance of data cables (102) for a vehicle in a spatially resolved manner is presented. The test apparatus (100) comprises a pulse cable (108); a voltage source (104) for charging the pulse cable (108) via a high-value resistor (106); a switch (110) which is set up to connect the pulse cable (108) to a data cable (102) to be tested in order to discharge the charged pulse cable (108) to the data cable (102) to be tested; a measuring device (112) for measuring a voltage curve (120) between the pulse cable (108) and the data cable (102) to be tested while the pulse cable (108) is discharged to the data cable (102) to be tested; and an evaluation device (122) which is set up to evaluate the voltage curve (120) in order to determine a fault in a spatially resolved manner.
(FR) L’invention concerne un dispositif de contrôle (100) pour la mesure d’impédance à résolution spatiale de câbles de données (102) pour un véhicule. Le dispositif de contrôle (100) comprend un câble à impulsions (108) ; une source de tension (104) destinée à charger le câble à impulsions (108) à travers une résistance (106) fortement ohmique ; un commutateur (110) qui sert à relier le câble à impulsions (108) à un câble de données (102) à contrôler afin de décharger le câble à impulsions (108) chargé dans le câble de données (102) à contrôler ; un dispositif de mesure (112) destiné à mesurer une courbe de tension (120) entre le câble à impulsions (108) et le câble de données (102) à contrôler, lors de la décharge du câble à impulsions (108) dans le câble de données (102) à contrôler ; et un dispositif d’évaluation (122) qui sert à évaluer la courbe de tension (120) pour déterminer un défaut avec une résolution spatiale.
(DE) Es wird eine Prüfvorrichtung (100) zur ortsaufgelösten Impedanzmessung von Datenkabeln (102) für ein Fahrzeug vorgestellt. Die Prüfvorrichtung (100) umfasst ein Pulskabel (108); eine Spannungsquelle (104) zum Laden des Pulskabels (108) über einen hochohmigen Widerstand (106); einen Schalter (110), der dazu eingerichtet ist, das Pulskabel (108) mit einem zu prüfenden Datenkabel (102) zu verbinden, um das geladene Pulskabel (108) auf das zu prüfende Datenkabel (102) zu entladen; eine Messeinrichtung (112) zum Messen eines Spannungsverlaufs (120) zwischen dem Pulskabel (108) und dem zu prüfenden Datenkabel (102), während das Pulskabel (108) auf das zu prüfende Datenkabel (102) entladen wird; und eine Auswerteeinrichtung (122), die eingerichtet ist, den Spannungsverlauf (120) auszuwerten, um eine Störstelle ortsaufgelöst zu ermitteln.
