Abstract
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.
Claims20
A method for monitoring a plurality of door assemblies at a facility, wherein each door assembly of the plurality of door assemblies in the facility comprises a door, a door frame, a hinge connecting the door to the door frame, an energy sensor, a memory and a door controller, the method comprising:
- generating a plurality of energy signature signals with the energy sensor of each door assembly,
- comparing each energy signature signal of the plurality of energy signature sensors to a door component operating signature stored in the memory of each corresponding door assembly,
- generating a plurality of door component operation status signals in response to the comparing,
- communicating the plurality of door component operation status signals to a central controller or a manufacturer controller;
- and
- generating a report with the central controller or the manufacturer controller,
- wherein the energy sensor is located on the door frame or the hinge of each corresponding door assembly,
- the door component operation status signal corresponds to a door-to-frame clearance and a door-to-ground clearance, and
- the energy sensor comprises an accelerometer.
A door assembly comprising:
- a door;
- a door frame;
- a hinge connecting the door to the door frame;
- an energy sensor generating an energy signature signal;
- a memory storing a door component operating signature;
- a door controller coupled to the energy sensor,
- wherein the door controller 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,
- the energy sensor comprises an accelerometer,
- the energy sensor is located on the door frame or the hinge, and
- the door component operation status signal corresponds to a door-to-frame clearance and a door-to-ground clearance.
A method of monitoring a plurality of door assemblies, wherein each door assembly of the plurality of door assemblies comprises a door, a door frame, and a hinge, the method comprising:
- attaching an energy sensor to the door frame or the hinge of each corresponding door assembly,
- generating an energy signature signal with the energy sensor,
- comparing the energy signature signal to a door component operating signature, and
- generating a door component operation status signal in response to the comparison,
- wherein the door controller compares the energy signature signal to a door component operating signature stored in a memory,
- the energy sensor comprises an accelerometer, and
- the door component operation status signal corresponds a door-to-frame clearance and a door-to ground clearance.
