A system for monitoring pressure change within at least one compartment of an aircraft is provided. The system in-cludes a primary pressure sensor for providing a signal corresponding to a pressure within a primary compartment of the aircraft, a primary monitoring channel coupled to the primary pressure sensor, and an output driver coupled to the primary monitoring chan-nel. The primary monitoring channel includes a band pass filter for receiving and filtering the primary pressure signal, a pressure change circuit for determining a change in the filtered pressure signal and for providing a pressure change output signal corre-sponding to the change in pressure, and a threshold logic circuit for determining whether the pressure change output signal meets a predetermined threshold and for providing a threshold output signal indicating that a decompression event has occurred if the pressure change output signal meets the predetermined threshold. The output driver receives the primary threshold output signal and outputs a notification signal.
Système de surveillance des variations de pression à lintérieur dau moins un compartiment dun aéronef, le système comprenant un capteur de pression primaire destiné à produire un signal correspondant à une pression à lintérieur dun compartiment primaire de laéronef, un canal de surveillance primaire couplé au capteur de pression primaire, et un circuit pilote de sortie couplé au canal de surveillance primaire. Le canal de surveillance primaire comprend un filtre passe-bande destiné à recevoir et à filtrer le signal de pression primaire, un circuit de variation de pression destiné à identifier une variation du signal de pression filtré et à produire un signal de sortie de variation de pression correspondant à la variation de pression, et un circuit logique à seuil destiné à établir si le signal de sortie de variation de pression correspond à un seuil préétabli et à produire un signal de sortie seuil indiquant quune décompression sest produite si le signal de sortie de variation de pression correspond au seuil préétabli. Le circuit pilote reçoit le signal de sortie seuil primaire et produit un signal davertissement.
