An apparatus in one example comprises an airflow manipulating device, a portable control device, and an air pressure sensor. The airflow manipulating device is disposed between a source of compressed air and an air brake line of a train consist. The portable control device is in wireless communication with the airflow manipulating device. The portable control device is transportable by a user along the train consist during inspection of the air brake line. The portable control device is adapted to transmit a control signal over a wireless communication channel to move a valve in the airflow manipulating device to a position that causes an increase or decrease of air pressure in the air brake line. The air pressure sensor measures an air pressure level in the air brake line for wireless transmission to the portable control device.

L'invention concerne, dans un exemple, un appareil qui comprend un dispositif de manipulation de flux d'air, un dispositif de commande portable, et un capteur de pression d'air. Le dispositif de manipulation de flux d'air est placé entre une source d'air comprimé et une conduite de frein à air d'une composition de trains. Le dispositif de commande portable communique sans fil avec le dispositif de manipulation de flux d'air. Le dispositif de commande portable peut être transporté par l'utilisateur le long de la composition de trains lors de l'inspection de la conduite de frein à air. Le dispositif de commande portable est destiné à transmettre un signal de commande sur le canal de communications sans fil pour déplacer une soupape dans le dispositif de manipulation de flux d'air vers une position qui provoque une augmentation ou une diminution dans la conduite de frein à air. Le capteur de pression d'air mesure un niveau de pression d'air dans la conduite de frein à air pour transmission sans fil au dispositif de commande portable.
