Abstract

Described herein is the location of an air leak in a network for supplying pressurized air that includes one or more components and at least one leak detection loop including one or more sensing elements. The location includes receiving information representative of detection of the leak by a sensing element of the detection loop, receiving a 3D model of at least part of the network for supplying pressurized air, interrogating a database associating a leak site of a component with each location on the detection loop, determining a precise location of the leak on the network for supplying pressurized air, mapping the precise location relative to a component, and instructing display of the 3D model corresponding to the component of the supply network and of the precise location.

Claims (26)

1. A method for locating an air leak in a network for supplying pressurized air comprising a plurality of components and at least one leak detection loop comprising a plurality of sensing elements, comprising:

receiving information representative of detection of the leak by a sensing clement of said detection loop, said information comprising a reference to the sensing element having detected the leak and a location on the detection loop,

receiving a 3D model of at least part of the network for supplying pressurized air,

interrogating a database associating a leak site of a component of the supply network with each location on the detection loop,

determining, from said information representative of detection and from said database, a precise location of said leak on the network for supplying pressurized air,

mapping said precise location relative to a component of the supply network, and

instructing display of the 3D model corresponding to said component of the supply network and of said precise location;

modeling the 3D model, said 3D model comprising 3D models of components of the supply network and of the detection loop.

2. The method of claim 1 , further comprising a preliminary step of creating the database associating a leak site of a component of the supply network with each location on the detection loop.

3. The method of claim 1 , wherein the preliminary step of modeling the 3D model comprises the modeling of collars configured for attaching the detection loop to the supply network.

4. The method of claim 1 , wherein the database comprises the association between the location on the detection loop and each attachment collar of the supply network modeled in the 3D model.

5. A non-transitory computer program product for locating an air leak in a network for supplying pressurized air comprising a plurality of components and at least one leak detection loop comprising a plurality of sensing elements, said computer program product comprising program code instructions in order to execute, when said computer program product is executed on a computer, the following steps:

receiving information representative of detection of the leak by a sensing element of said detection loop, said information comprising a reference to the sensing element having detected the leak and a location on the detection loop,

receiving a 3D model of at least part of the network for supplying pressurized air,

interrogating a database associating a leak site of a component of the supply network with each location on the detection loop,

determining, from said information representative of detection and from said database, a precise location of said leak on the network for supplying pressurized air,

mapping said precise location relative to a component of the supply network, and, instructing display of the 3D model corresponding to said component of the supply network and of said precise location; and

the 3D model comprising 3 D models of components of the supply network and of the detection loop.

6. A system for locating an air leak in a network for supplying pressurized air comprising a plurality of components and at least one leak detection loop comprising a plurality of sensing elements, comprising:

a module for receiving information representative of detection of the leak by a sensing element of said detection loop, said information comprising a reference to the sensing element having detected the leak and a location on the detection loop,

a module for receiving a 3D model of at least part of the network for supplying pressurized air,

a module for interrogating a database associating a leak site of a component of the supply network with each location on the detection loop,

a module for determining, from said information representative of detection and from said database, a precise location of said leak on the network for supplying pressurized air,

a module for mapping said precise location relative to a component of the supply network,

a module for instructing display of the 3D model corresponding to said component of the supply network and of said precise location; and

the 3D model comprising 3D models of components of the supply network and of the detection loop.
