Method and system for monitoring of the temperature of the surface of an aircraft
First Claim
1. A method for monitoring the temperature of the outer skin of an aircraft, in which a camera connected to a first processing unit for imaging detection of at least one region of the outer surface of the aircraft, records an image once, several times, or at regular intervals and transmits this to the first processing unit, wherein the light spectrum which may be detected by the camera lies in the infrared range and the first processing unit determines the temperatures of pictorially detected locations or has these determined by a downstream signal-processing device, characterized inthat the camera is disposed on the vertical stabilizer of the aircraft,that the camera measures at least one area of the upwardly pointing outer surface of the airplane,that the method is performed before the start of the airplane,that the first processing unit compares the temperature for individual locations with a predetermined maximum design temperature for the relevant location, and, if the maximum design temperature is exceeded, generates a warning signal, wherein simultaneously the recorded image is displayed on a display device disposed in the cockpit of the aircraft, wherein the display device, the first or a second processing unit, or another signal-processing device changes the colors of the recorded image displayed on the display device such that each temperature on the surface is allocated a different color.

Abstract
The invention relates to a method and a system for monitoring the temperature of an aircraft, in which at least one camera connected to a first processing unit, for imaging detection of at least one region of the substantially upwardly-pointing outer surface of the aircraft, detects an images once, several times, or at regular intervals and transmits this to the first processing unit, wherein the light spectrum which may be detected by the camera lies substantially in the infrared range and the first processing unit determines the temperatures of substantially all the pictorially detected locations or has these determined by a downstream signal-processing device, in each case compares the temperature for individual locations with a predetermined maximum design temperature for the relevant location, and if the maximum design temperature is exceeded, generates a warning signal. The warning signal may be used to prevent takeoff of the aircraft, wherein the determined exceeding of the temperature may be checked by checking the measurements by means of a thermographic image of the surface of the aircraft in the cockpit of the aircraft and the prevention of takeoff may be deactivated if necessary.

23. A method for monitoring the temperature of the outer skin of an aircraft using a camera disposed on a vertical stabilizer of the aircraft and arranged to measure at least one area of an upwardly pointing outer surface of the aircraft, comprising, prior to a starting of the aircraft:
-
detecting an image of at least one region of the upwardly pointing outer surface of the aircraft with the camera connected to a first processing unit; recording an image once, several times, or at regular intervals; transmitting the recorded image to the first processing unit, wherein the light spectrum which may be detected by the camera lies in the infrared range; one of the first processing unit and a downstream signal-processing device determining the temperatures of pictorially detected locations; and the first processing unit comparing the temperature for individual locations with a predetermined maximum design temperature for the relevant location, and, if the maximum design temperature is exceeded, generating a warning signal, wherein simultaneously the recorded image is displayed on a display device disposed in the cockpit of the aircraft, wherein at least one of the display device, the first or a second processing unit or another signal-processing device is operable to change the colors of the recorded image displayed on the display device such that each temperature on the surface is allocated a different color.
