Abstract

A device for monitoring an immobile space region includes: a radar transmitting device fixedly installed with respect to the immobile space region and configured for emitting radar beams; a radar receiving device fixedly installed with respect to the immobile space region and configured for receiving the emitted radar beams reflected at an object in the immobile space region; an evaluation device for evaluating the received radar beams using a predetermined evaluation model for determining a position and/or a trajectory of the object in the immobile space region; a control unit for generating a control signal based on a predetermined decision model as well as based on the determined position and/or the determined trajectory of the object; and an actuator device controlled using the control signals generated by the control unit.

Claims

1. A method for monitoring an immobile space region, comprising:

emitting radar beams into the immobile space region by using a radar transmitting device fixedly installed with respect to the immobile space region;

receiving, by a radar receiving device fixedly installed with respect to the immobile space region, the emitted radar beams reflected in the immobile space region at an object;

evaluating, by an evaluation device, the received radar beams with the aid of a predetermined evaluation model for determining at least one of a first position and a trajectory of the object in the immobile space region;

generating, by a control unit, a control signal based on a predetermined decision model and at least one of the determined first position and the determined trajectory of the object; and

actuating an actuator device of the using the generated control signal.

2. The method as recited in claim 1, wherein:

at least one of the predetermined evaluation model and the predetermined decision model includes selected information on a second position of a structure with reference to the radar receiving device;

during the evaluation of the received radar beams, a first relative motion of the object is determined relative to the structure, based on the selected information; and

the control signal is generated further based on the determined first relative motion of the object relative to the structure.

3. The method as recited in claim 2, wherein:

during the evaluation of the received radar beams, a second relative motion of the object is determined relative to the radar receiving device; and

the control signal is generated further based on the determined second relative motion of the object relative to the radar receiving device.

4. The method as recited in claim 2, wherein:

during the evaluation of the received radar beams, a length of stay of the object in the space region is determined; and

the control signal is generated further based on the determined length of stay of the object.

5. A device for monitoring an immobile space region, comprising:

a radar transmitting device for emitting radar beams, said radar transmitting device being fixedly installed with regard to the immobile space region;

a radar receiving device fixedly installed with respect to the immobile space region for receiving the emitted radar beams which are reflected at an object in the immobile space region;

an evaluation device for evaluating the received radar beams by using a predetermined evaluation model for determining at least one of a first position and a trajectory of the object in the immobile space region;

a control unit for generating a control signal based on a predetermined decision model and at least one of the determined first position and the determined trajectory of the object; and

an actuator device controlled by the control signal generated by the control unit.

6. The device as recited in claim 5, wherein:

at least one of the predetermined evaluation model and the predetermined decision model includes information on a second position of a structure with reference to the radar receiving device;

the evaluation device is further configured to determine a first relative motion of the object relative to the structure, based on the information on the second position; and

the control unit is configured to generate the control signal further based on the determined first relative motion of the object relative to the structure.

7. The device as recited in claim 6, wherein:

the evaluation device is configured to further determine a second relative motion of the object relative to the radar receiving device; and

the control unit is configured to generate the control signal further based on the determined second relative motion of the object relative to the radar receiving device.

8. The device as recited in claim 6, wherein:

the evaluation device is configured to determine a length of stay of the object in the immobile space region; and

the control unit is configured to generate the control signal further based on the determined length of stay of the object in the immobile space region.

9. The device as recited in claim 6, further comprising:

a housing, wherein at least the radar transmitting device, the radar receiving device, the evaluation device, and the control unit are situated within the housing, and wherein the structure is an immobile structure, and wherein the housing is fixedly installed on the immobile structure with respect to the immobile space region.

10. The device as recited in claim 6, further comprising:

an interface, wherein at least one of the evaluation model of the evaluation device and the decision model of the control unit is adapted using the interface.
