Claims

1. An automatically opening and closing controlled door is installed in the opening, An image sensor is provided around the door to detect a person or object within a detection area, An abnormality detection unit that determines an abnormality in the image sensor based on the pixel values ​​of multiple imaging data acquired in the same area, A control unit controls the opening and closing drive of the door based on the detection results of the image sensor, An automatic door system equipped with the following features.

2. The abnormality detection unit determines a pixel abnormality based on the difference in pixel values ​​of the multiple imaging data acquired in the same area with different sensitivity settings. The automatic door device according to claim 1.

3. The abnormality detection unit determines pixel abnormalities based on the difference in pixel values ​​of multiple data sets, where the number of combinations of imaging data acquired with a single sensitivity in the same area differs by one or more. The automatic door device according to claim 1.

4. When the abnormality detection unit determines that there is an abnormality, it instructs the control unit to restrict the opening and closing of the door. The automatic door device according to claim 1.

5. The system includes a notification unit that notifies when the abnormality detection unit determines that an abnormality has occurred. The automatic door device according to claim 1.

6. The abnormality detection unit determines whether there is a moving person or object in the multiple imaging data acquired in the same area, and if there is no movement, it determines whether there is an abnormality. The automatic door device according to claim 1.

7. The abnormality detection unit uses the imaging data when the door is fully closed. The automatic door device according to claim 1.

8. The abnormality detection unit determines an abnormality if the brightness difference used as the difference in pixel values ​​is within a reference value. The automatic door device according to claim 2 or claim 3.

9. It is equipped with an illuminance information acquisition unit that acquires illuminance information, If the illuminance is below the threshold, the abnormality detection unit instructs the control unit to stop the door in the fully open position. The automatic door device according to claim 1.

10. When the sensitivity is low, the abnormality detection unit determines that there is an abnormality if the brightness difference used as the difference in pixel values ​​is greater than or equal to a reference value. The automatic door device according to claim 2 or claim 3.

11. The anomaly detection unit determines the presence or absence of edges from the imaging data, and determines an anomaly when edges are no longer detected. The automatic door device according to claim 1.

12. The system includes a data storage unit that stores image sensor information when the abnormality detection unit makes a determination. The automatic door device according to claim 1.

13. The system includes an output unit that outputs image sensor information when the abnormality detection unit makes a determination. The automatic door device according to claim 1.

14.
