Abstract

Procédé de recherche de fuite dans une canalisation mettant en œuvre un dispositif mobile interne et autonome de mesure. Ce procédé utilise un dispositif interne pour la recherche de fuite dans un tuyau grâce à la mesure de la pression en continu. Basé sur le principe d’introduction/extraction, l’outil se déplace grâce au flux généré dans la canalisation et enregistre des données de pression à haute résolution. Une fois récupéré, la lecture des données, couplées aux informations d’intervention permet une localisation des fuites de la conduite inspectée. L’appareil est composé d’une coque résistante à la pression, d’un capteur de mesure de pression, d’une mémoire interne, d’un microcontrôleur et d’une interface de transmission des données. Les fuites sont détectées sur le principe d’apparition au droit de la dite fuite d’une dépression ou surpression par rapport à la pression environnante.A method of searching for a leak in a pipe using an internal and autonomous mobile measuring device. This process uses an internal device to find a leak in a pipe by measuring the pressure continuously. Based on the introduction / extraction principle, the tool moves thanks to the flow generated in the pipe and records high resolution pressure data. Once recovered, reading the data, coupled with the intervention information, enables the location of leaks in the inspected pipe. The device consists of a pressure-resistant shell, a pressure measurement sensor, internal memory, a microcontroller and a data transmission interface. Leaks are detected on the principle of appearance at the right of said leak of a depression or overpressure in relation to the surrounding pressure.

un dispositif autonome destiné à être inséré dans une canalisation avec un point d’entrée et un point de sortiea self-contained device intended to be inserted into a pipeline with an entry point and an exit point

un appareil électronique avec des moyens pour mesurer la pression à haute résolution et stocker les données en interne
Dans un premier temps le dispositif est inséré dans la canalisation en charge. Il se déplace grâce au flux généré dans le tuyau et mesure les données le long de son parcours.
Ensuite le dispositif est récupéré et ses données sont lues et analysées. Les contraintes hydrauliques d’intervention comme le diamètre interne de la canalisation, le débit généré et le temps de parcours sont nécessaire à l’exploitation des données. Une fuite est déterminée par l’apparition d’une surpression ou dépression au droit de la dite fuite par rapport à la pression environnante.an electronic device with means to measure pressure at high resolution and store the data internally
First, the device is inserted into the pipe under load. It moves thanks to the flow generated in the pipe and measures the data along its route.
Then the device is retrieved and its data is read and analyzed. The hydraulic intervention constraints such as the internal diameter of the pipe, the flow generated and the travel time are necessary for the exploitation of the data. A leak is determined by the appearance of an overpressure or depression in line with said leak in relation to the surrounding pressure.

Bien sûr, l’invention n’est pas limitée aux exemples qui viennent d’être décrits et de nombreux aménagement peuvent être apportés sans sortir du cadre de l’invention.Of course, the invention is not limited to the examples which have just been described and many adjustments can be made without departing from the scope of the invention.
