Abstract

A method for ascertaining a closing state of a house door or of a house window, having the following method steps: acquisition of a rate of rotation of the house door or of the house window using a first acquisition device, and calculation of an opening angle of the house door or of the house window on the basis of the acquired rate of rotation, and ascertaining whether the calculated opening angle falls below a prespecified angular threshold value; acquisition of a rate of vibration of the house door or of the house window using a second acquisition device, and ascertaining whether the acquired rate of vibration exceeds a prespecified rate of vibration threshold value within a prespecified first time span; and ascertaining whether the acquired rate of rotation exceeds a prespecified rate of rotation threshold value within a prespecified second time span since the exceeding of the vibration rate threshold value.

First claim

What is claimed is:

1. A method for ascertaining a closing state of one of a house door and a house window, comprising:
acquiring, during a movement of the one of the house door and the house window, a rate of rotation of the one of the house door and the house window using a first acquisition device;
calculating, during the movement of the one of the house door and the house window, an opening angle of the one of the house door and the house window on the basis of the acquired rate of rotation;
ascertaining, during the movement of the one of the house door and the house window, whether the calculated opening angle falls below a prespecified angular threshold value;
acquiring, during the movement of the one of the house door and the house window, a rate of vibration caused by mechanical oscillations of the one of the house door and the house window using a second acquisition device; and
ascertaining the closing state by ascertaining:
whether the acquired rate of vibration exceeds a prespecified rate of vibration threshold value within a prespecified first time, and
whether the acquired rate of rotation exceeds a prespecified rate of rotation threshold value within a prespecified second time span since an exceeding of the vibration rate threshold value.

2. The method as recited in claim 1 , wherein during at least one of the first and the second time span, a continuous acquisition takes place of the rate of rotation of the one of the house door and the house window using the first acquisition device, and a calculation of the opening angle of the one of the house door and the house window on the basis of the acquired rate of rotation, and it is ascertained whether the calculated opening angle falls below the prespecified angular threshold value.

3. The method as recited in claim 1 , wherein after a closing of the one of the house door and the house window has been ascertained, the angular threshold value is calibrated.

4. The method as recited in claim 1 , wherein as the first time span includes one of up to 3 seconds, up to 1.5 seconds, and up to 0.1 seconds.

5. The method as recited in claim 1 , wherein the second time span includes a time span of one of up to 20 seconds, up to 10 seconds, and up to 5 seconds.

6. A device for ascertaining a closing state of one of a house door and a house window, comprising:
a first acquisition device for acquiring, during a movement of the one of the house door and the house window, a rate of rotation of the one of the house door and the house window;
a second acquisition device for acquiring, during the movement of the one of the house door and the house window, a rate of vibration caused by mechanical oscillations of the one of the house door and the house window;
a computing device for calculating, during the movement of the one of the house door and the house window, an opening angle on the basis of the acquired rate of rotation;
an ascertaining device for ascertaining, during the movement of the one of the house door and the house window, whether the calculated opening angle falls below a prespecified angular threshold value; and
a monitoring device for ascertaining the closing state of the one of the house door and the house window by determining;
whether the rate of vibration exceeds a vibration rate threshold value within a prespecified first time span, and
whether the acquired rate of rotation exceeds a prespecified rate of rotation threshold value within a prespecified second time span since an exceeding of the vibration rate threshold value.

7. The device as recited in claim 6 , wherein the first acquisition device includes a rotational rate sensor for acquiring data relating to a currently prevailing rate of rotation of the one of the house door and the house window.

8. The device as recited in claim 6 , wherein the second acquisition device includes a vibration sensor for acquiring mechanical vibrations of the one of the house door and the house window.

9. The device as recited in claim 6 , wherein the computing device temporally integrates the acquired rate of rotation in order to calculate the opening angle of the one of the house door and the house window.
