Abstract

A mobile apparatus is provided for measuring photometric characteristics of airport marker lights. The mobile apparatus includes a measuring rod configured to be moved above the marker lights to be checked, in light beams emitted by these marker lights, and a device for measuring the distance between the measuring rod and the marker lights to be checked. The measuring rod carries at least one photometric sensor and includes a device for acquiring and processing the signals emitted by the photometric sensor or sensors during its movement, as a function of the distance measured between the measuring rod and the marker lights to be checked. The device for acquisition and processing is configured to generate a set of data representing photometric characteristics of each marker light checked.

Claims

1. A mobile apparatus for measuring photometric characteristics of airport marker lights, the mobile apparatus comprising:

a measuring rod configured to be moved above the marker lights to be checked, in the light beams emitted by these marker lights, and

means for measuring a distance between said measuring rod and the marker lights to be checked, said measuring rod carrying at least one photometric sensor,

wherein said measuring rod comprises means for acquiring and processing signals emitted by said at least one photometric sensor during its movement, as a function of the distance measured between said measuring rod and the marker lights to be checked, said means for acquiring and processing being configured for generating a set of data representing photometric characteristics of each marker light checked.

2. The mobile measurement apparatus according to claim 1, wherein said measuring rod constitutes a Faraday cage protecting said sensors and/or said means for acquiring and processing against electromagnetic radiation.

3. The mobile measurement apparatus according to claim 1, wherein said set of data representing the photometric characteristics of each checked marker light is a digital signal.

4. The mobile measurement apparatus according to claim 1, wherein said measuring rod carries means for transmitting said set of data to a computer enabling recording of said sets of data and/or to an interface with a user.

5. The mobile measurement apparatus according to claim 4, wherein said means for transmitting comprise means for radio transmission.

6. The mobile measurement apparatus according to claim 5, wherein said means for radio transmission are constituted by a radio transmitter complying with a WiFi standard.

7. The mobile measurement apparatus according to claim 1, wherein said measuring rod comprises a plurality of frontward-oriented photometric sensors.

8. The mobile measurement apparatus according to claim 7, wherein said measuring rod furthermore comprises a plurality of rearward-oriented photometric sensors.

9. The mobile measurement apparatus according to claim 1, wherein said measuring rod comprises at least one photometric sensor configured to detect downward-oriented marker lights.

10. The mobile apparatus according to claim 9, wherein said means for measuring the distance between said measuring rod and the lights to be checked include said photometric sensor for detecting marker lights and means for measuring a speed of movement of said measuring rod.

11. The mobile measurement apparatus according to claim 1, wherein said measuring rod comprises means for colorimetric analysis of the marker lights checked.

12. The mobile measurement apparatus according to claim 1, wherein said means for processing are constituted by an industrial programmable automaton placed in said measuring rod.

13. The mobile measurement apparatus according to claim 1, wherein the apparatus comprises a geolocation receiver enabling each set of data representing the photometric characteristics of a marker light to be associated with the geolocation coordinates of this marker light.
