Method of detecting collisions on an airport installation and device for its implementation
First Claim
1. A method for detecting collisions between an equipped mobile object travelling around an airport installation and at least one obstacle whose position is known in a reference frame tied to the airport installation, the method comprising the steps:
- determining the real-time positions of the equipped mobile object in the reference frame tied to the airport installation,reading at least one item of information contained in at least one marker fixed to the equipped mobile object and positioned in a reading field of at least one reader of a network of readers deployed over at least one zone of the airport installation,determining an outline of the equipped mobile object on the basis of the read item of information contained in the marker,positioning the outline determined in the reference frame tied to the airport installation,calculating a distance between the outline of the equipped mobile object and the obstacle, andtriggering an alert if the calculated distance is less than a given threshold.

Abstract
A method of detecting collisions between an equipped mobile object travelling around an airport installation and at least one obstacle. The method comprises the following steps. Determining the real-time positions of the equipped mobile object in a reference frame tied to the airport installation. Reading at least one item of information contained in at least one marker fixed to the equipped mobile object. Determining an outline of the equipped mobile object on the basis of the read item of information contained in the marker. Positioning the outline determined in the reference frame tied to the airport installation. Triggering an alert if the distance between the outline of the equipped mobile object and the obstacle is less than a given threshold.

7. A device for detecting collisions between an equipped mobile object travelling around an airport installation and at least one obstacle whose position is known in a reference frame tied to the airport installation, the device comprising:
-
at least one marker fixed to the equipped mobile object comprising at least one marker identifier, a network of readers deployed over at least one zone of the airport installation, each reader having a reading field and being configured to automatically collect at least the marker identifier of each marker present in its reading field, an information processing unit comprising a piece of software configured to; determine a position in real time of the equipped mobile object in the reference frame tied to the airport installation, determine at least one outline of the equipped mobile object, calculate a distance between the outline of the equipped mobile object and the obstacle, and trigger an alert if the calculated distance is less than a given threshold. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
