Abstract

To improve the accuracy of the determination on whether or not a moving object is present in a predetermined region, a control device for use in a system configured to conduct presence-or-absence determination on whether or not a moving object is present on the basis of detection by a first sensor provided in a predetermined compartment region, the control device comprising: a mode control section configured to control switching of an operation mode for the detection by the first sensor or the presence-or-absence determination; and an acquisition section configured to acquire a determination result of whether or not a moving object is present in an adjacent region adjacent to the predetermined compartment region and not including the predetermined compartment region; wherein the mode control section controls the switching of the operation mode in response to the determination result acquired by the acquisition section, is provided.

Claims

1. A control device for use in a system configured to conduct presence-or-absence determination on whether or not a moving object is present on the basis of detection by a first sensor provided in a predetermined compartment region, the control device comprising:

a mode control section configured to control switching of an operation mode for the detection by the first sensor or the presence-or-absence determination; and

an acquisition section configured to acquire a determination result of whether or not a moving object is present in an adjacent region adjacent to the predetermined compartment region and not including the predetermined compartment region;

wherein the mode control section controls the switching of the operation mode in response to the determination result acquired by the acquisition section.

2. The control device according to claim 1, wherein

the first sensor is a Doppler sensor configured to generate a Doppler signal on the basis of a transmitted wave and a received wave including a reflected wave of the transmitted wave.

3. The control device according to claim 1, wherein

the mode control section

switches the operation mode to a first operation mode when a determination result indicating that a moving object is not present in the adjacent region is acquired by the acquisition section, and

switches the operation mode to a second operation mode when a determination result indicating that a moving object is present in the adjacent region is acquired, and

in the second operation mode, a situation in which a determination result indicating that a moving object is present is obtained in the presence-or-absence determination is more limited than in the first operation mode.

4. The control device according to claim 3, wherein

the detection by the first sensor is stopped in the second operation mode.

5. The control device according to claim 3, wherein

a scope of detection by the first sensor is reduced in the second operation mode.

6. The control device according to claim 3, wherein

in the second operation mode, a direction of detection by the first sensor is changed to an opposite side from the adjacent region.

7. The control device according to claim 3, wherein

the presence-or-absence determination is conducted by comparing a value obtained on the basis of the detection by the first sensor and a threshold value, and

a different value is applied as the threshold value in the first operation mode from in the second operation mode.

8. The control device according to claim 1, wherein

a plurality of first sensors are provided in the predetermined compartment region, and

the control device further comprises a determination section configured to determine whether or not a moving object is present on the basis of the detection by the first sensors, and

the determination section conducts determination on whether or not a moving object is present by using each detection by the first sensors with a weight according to the determination result acquired by the acquisition section.

9. The control device according to claim 1, wherein

the acquisition section determines whether or not a moving object is present in the adjacent region on the basis of a detection result by a second sensor of which a scope of detection includes the adjacent region.

10. The control device according to claim 9, wherein

the second sensor is a human-sensing sensor.

11. The control device according to claim 9, wherein

the second sensor is an image sensor.

12. The control device according to claim 9, wherein

the second sensor is a human-operated switch sensor provided for the predetermined compartment region.

13. The control device according to claim 1, wherein

the adjacent region is a region that a human being steps in when patrolling the predetermined compartment region, and

the acquisition section determines whether or not a human being, which is a moving object, is present in the adjacent region, on the basis of a preset patrol schedule of a human being.

14. The control device according to claim 1, further comprising

a display control section configured to cause a display section to display a determination result of whether or not a moving object is present, obtained on the basis of the detection by the first sensor.

15. The control device according to claim 14, wherein

the display control section causes the display section to further display information indicating in which operation mode the determination result based on the detection by the first sensor is obtained.

16. The control device according to claim 1, further comprising

a storage section configured to store a history of the determination result based on the detection by the first sensor.

17. The control device according to claim 1, wherein

the moving object is a human being.

18. A control system configured to conduct presence-or-absence determination on whether or not a moving object is present on the basis of detection by a first sensor provided in a predetermined compartment region, the control system comprising:

the first sensor;

a second sensor of which a scope of detection includes an adjacent region adjacent to the predetermined compartment region and not including the predetermined compartment region; and

a control device including

a mode control section configured to control switching of an operation mode for the detection by the first sensor or the presence-or-absence determination, and

an acquisition section configured to acquire a determination result of whether or not a moving object is present in the adjacent region on the basis of communication with the second sensor,

wherein the mode control section controls the switching of the operation mode in response to the determination result acquired by the acquisition section.
