Abstract
The invention relates to a method and an arrangement for recognizing potential overheating of an object. For this purpose the temperature of the object is measured by means of temperature sensors. A signal processing arrangement determines the temperature gradient from the measured temperature values. A comparator compares the determined value of the temperature gradient with a threshold value generated by a threshold value generator. When the threshold value is exceeded, a warning signal generator triggers a warning signal. This warning signal can be an acoustical or optical signal. In addition or alternatively, the warning signal can activate a protective measure arrangement.
Claims3
A method for the early recognizing of a potential overheating of an object comprising an internal combination engine or thruster having a fuel supply, the method comprising the steps of:
- measuring the temperature of said object and determining temperature values;
- determining a temperature gradient from said temperature values;
- comparing a value of said temperature gradient with a predetermined value;
- triggering a warning signal in dependence upon said comparison of said determined value of the temperature gradient with said predetermined value;
- and
- interrupting said fuel supply in dependence of said triggered warning signal.
An arrangement for the early recognizing of a potential overheating of an object comprising an internal combustion engine or thruster having a fuel supply, comprising:
- at least one temperature sensor for measuring the temperature of said object;
- signal processing means for determining the temperature gradient from temperature values measured by said at least one temperature sensor;
- comparator means for comparing a determined value of said temperature gradient with a predetermined value and for outputting a comparator signal;
- warning signal generating means for triggering a warning signal in dependence upon said comparator signal;
- and
- interrupting means for interrupting said fuel supply in dependence upon said triggered warning signal.
