Abstract

In example implementations, a door monitoring sensor is provided. The door monitoring sensor includes a communication interface to transmit an alarm when a door operates outside of operational parameters of the door, an angular sensor to measure rotational movement of the a door, a movement sensor to detect movement along an x-y-z coordinate plane, a radar sensor to detect an object, a rechargeable power supply to provide power to the angular sensor, the movement sensor, and the radar sensor, and a processor. The processor is communicatively coupled to the communication interface, the angular sensor, the movement sensor, and the radar sensor. The processor is to determine that the door is moving outside of the operational parameters of the door and generate the alarm that is transmitted by the communication interface in response to determination that the door is moving outside of the operational parameters of the door.

First claim

The invention claimed is:

1. A door monitoring sensor, comprising:
a communication interface to transmit a communication when a door operates outside of operational parameters that are unique to the door;
an angular sensor to measure rotational movement of the door;
a movement sensor to detect movement along an x-y-z coordinate plane of the door;
a radar sensor to detect an object;
a rechargeable power supply to provide power to the angular sensor, the movement sensor, and the radar sensor, wherein a housing of the door monitoring sensor comprises contacts that electrically connect to contacts of a power source when the door is in a desired position; and
a processor communicatively coupled to the communication interface, the angular sensor, the movement sensor, and the radar sensor, wherein the processor is to:
determine that the door is moving outside of the operational parameters of the door; and
send a notification by the communication interface to a central monitoring system in response to a determination that the door is moving outside of the operational parameters that are unique to the door.

2. The door monitoring sensor of claim 1 , wherein the rotational movement measured by the angular sensor comprises pitch, roll, and yaw.

3. The door monitoring sensor of claim 1 , wherein the movement sensor comprises a gyroscope.

4. The door monitoring sensor of claim 1 , wherein the movement sensor comprises an accelerometer.

5. The door monitoring sensor of claim 1 , wherein the movement sensor comprises a level sensor.

6. The door monitoring sensor of claim 5 , wherein the level sensor is to determine that the door is level.

7. The door monitoring sensor of claim 1 , further comprising:
a memory to store the operational parameters that are unique to the door, wherein the operational parameters that are unique to the door are defined during an initialization process that monitors a plurality of opening and closing cycles of the door.

8. The door monitoring sensor of claim 7 , wherein the operational parameters that are unique to the door comprise an average of values recorded by the angular sensor and the movement sensor during the plurality of opening and closing cycles of the door.

9. The door monitoring sensor of claim 1 , wherein the processor is further to:
deactivate the radar sensor when the movement sensor detects that the door is in an open position.

10. A door, comprising:
a vertically rolling door, comprising a plurality of panels having wheels;
a plurality of tracks to guide movement of the vertically rolling door via the wheels of the plurality of panels that roll inside of the plurality of tracks;
a door barrel to wrap the vertically rolling door around the door barrel when the vertically rolling door is opened; and
a door monitoring sensor to measure six different movements of the vertically rolling door and to transmit a notification to a central monitoring system when at least one of the six different movements is measured to be outside of unique operational parameters defined for the door.

11. The door of claim 10 , wherein the door monitoring sensor comprises:
a rechargeable power supply to power sensors of the door monitoring sensor.

12. The door of claim 10 , wherein the door monitoring sensor comprises:
an angular sensor to measure three different rotational movements of the vertically rolling door.

13. The door of claim 10 , wherein the door monitoring sensor comprises:
a movement sensor to detect movement along an x-y-z coordinate plane of the vertically rolling door.

14. The door of claim 13 , wherein the movement sensor comprises a level that is used to determine that the vertically rolling door is level.

15. The door of claim 10 , further comprising a radar sensor to detect an object and to return the vertically rolling door to a default position when the object is detected while the vertically rolling door is closing.

16. A method, comprising:
defining operational parameters unique to a door during an initialization process;
measuring a plurality of different movements during operation of the door;
determining that the door is malfunctioning when at least one of the plurality of different movements falls outside of the operational parameters of the door;
generating a notification; and
transmitting the notification to a central monitoring system in response to the determining.

17. The method of claim 16 , wherein the initialization process comprises:
performing a plurality of opening and closing cycles of the door;
measuring the plurality of different movements during the plurality of opening and closing cycles; and
calculating an average value for each one of the plurality of different movements during the plurality of opening and closing cycles to define the operational parameters of the door.

18. The method of claim 16 , wherein the plurality of different movements comprises a movement along an x-y-z coordinate plane, pitch, roll, and yaw.

19. The method of claim 16 , wherein one of the operational parameters comprises detection of an object via a radar sensor while the door is closing, and the method further comprises:
moving the door to a default position in response to the detection of the object.

20. The method of claim 19 , further comprising:
determining that the door is in an open position; and
deactivating the radar sensor in response to determining that the door is in the open position.
