Title
(EN) DETECTING VACUUM PRESSURE AND ANOMALOUS CYCLING IN A VACUUM SEWER SYSTEM
(FR) DÉTECTION DE PRESSION NÉGATIVE ET DE CYCLE ANORMAL DANS UN SYSTÈME D'ÉGOUT SOUS VIDE
Abstract
(EN) An example apparatus is for use in a system that includes a sewage pit, a suction pipe in the sewage pit, and a valve between the suction pipe and a vacuum pipe that connects to a sewer system. The apparatus includes a controller configured to perform operations that include: detecting a vacuum pressure in the vacuum pipe, determining that the vacuum pressure in the vacuum pipe is below a predefined pressure, and preventing the valve from opening in response to determining that the vacuum pressure in the vacuum pipe is below the predefined pressure.
(FR) L'invention concerne un appareil donné à titre d'exemple destiné à être utilisé dans un système qui comprend une fosse d'égout, un tuyau d'aspiration dans la fosse d'égout, et une soupape entre le tuyau d'aspiration et un tuyau à vide qui se raccorde à un système d'égout. L'appareil comprend un contrôleur configuré pour effectuer des opérations qui comprennent : la détection d'une pression de vide dans le tuyau à vide, la détermination que la pression de vide dans le tuyau à vide est inférieure à une pression prédéfinie, et la prévention de l'ouverture de la soupape en réponse à la détermination que la pression de vide dans le tuyau à vide est inférieure à la pression prédéfinie.
