Door monitoring system
A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.
1. A door assembly comprising:
a first door skin;
a second door skin spaced apart from the first door skin;
an energy sensor generating an energy signature signal;
a memory storing a door component operating signature;
a controller coupled to the energy sensor and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison,
wherein the door component operation status signal corresponds to both a hinge status and an indication that a person is trying to hang themselves from the door.
2. A door assembly as recited in claim 1 wherein the energy sensor comprises an accelerometer.
3. A door assembly as recited in claim 1 wherein the energy sensor comprises a multi-axis accelerometer.
4. A door assembly as recited in claim 1 wherein the energy sensor is disposed between the first door skin and the second door skin.
5. A door assembly as recited in claim 1 wherein the energy sensor, the memory, and the controller are disposed between the first door skin and the second door skin.
6. A door assembly as recited in claim 1 wherein the energy sensor and memory are disposed within a door operator assembly.
7. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to an improperly adjusted operator assembly.
8. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to a door position.
9. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to a door clearance.
10. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to a virtual force applied to the door.
11. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to an abuse of the door.
12. A system comprising:
a door assembly as recited in claim 1 ;
a central controller in communication with the controller.
13. A method comprising:
generating an energy signature signal during door operation;
comparing the energy signature signal to a door component operating signature; and
generating a door component operation status signal in response to comparing;
wherein the door component operation status signal corresponds to both a hinge status and an indication that a person is trying to hang themselves from the door.
14. A method as recited in claim 13 wherein generating the door component operation status signal also corresponds to an improperly adjusted door operator assembly.
15. A method as recited in claim 14 wherein generating the door component operation status signal also corresponds to a door position.
16. A method as recited in claim 13 wherein generating the door component operation status signal also corresponds to a door clearance.
17. A method as recited in claim 16 further comprising communicating the door operation status signal to a central controller.
