Abstract

A control system for a door includes: a controller; a door motor configured to be operatively connected to the controller; an object sensor configured to be operatively connected to the controller and to detect a presence of an object; and an operation sensor configured to be operatively connected to the controller and to detect movement of a door, and wherein the controller is configured to send a operation signal to the door motor to cause the door motor to operate when the controller detects both: a signal from the object sensor indicating that the operation sensor has detected the presence of and object; and a signal from the operation sensor indicating that the operation sensor has detected movement.

First claim

I claim:

1. A control system for a door comprising:
a controller;
a door motor configured to be operatively connected to the controller;
a first object sensor configured to be operatively connected to the controller and to detect a presence of an object; and
an operation sensor configured to be operatively connected to the controller and to detect movement of the door, and
wherein the controller is configured to send an operation signal to the door motor to cause the door motor to operate in response to the controller receiving both:
a signal from the first object sensor indicating that the first object sensor has detected the presence of the object; and
a signal from the operation sensor indicating that the operation sensor has detected the movement.

2. The control system of claim 1 , further comprising at least one second object sensor configured to be operatively connected to the controller and to detect the presence of the object, wherein the controller is further configured to send the operation signal to the door motor to cause the door motor to operate when the controller detects both:
a signal from at least one of the at least one second object sensor indicating that the at least one second object sensor has detected the presence of the object; and
the signal from the operation sensor indicating that the operation sensor has detected the movement.

3. The control system of claim 1 , wherein the operation sensor includes any one of a torque sensor, a motor current sensor, a motor movement sensor, or a sensor that is configured to detect rotational movement.

4. The control system of claim 1 , wherein the operation sensor is configured to sense movements associated with the door.

5. The control system of claim 1 , further comprising a revolving door and the door motor is operatively connected to the door.

6. The control system of claim 5 , wherein the first object sensor is mounted in a door frame.

7. The control system of claim 1 , wherein the first object sensor is configured to detect the presence of the object in an entranceway of a door system.

8. The control system of claim 1 , wherein the controller is configured to:
receive a plurality of inputs, the plurality of inputs comprising the signal from the object sensor, the signal from the operation sensor, and at least one additional input; and
send a plurality of outputs, the plurality of outputs comprising the operation signal and at least one additional output.

9. The control system of claim 1 , wherein the controller is configured to control at least one of either lights associated with a door system or a locking system associated with the door.

10. The control system of claim 1 , wherein the controller is configured to receive inputs from a remote device.

11. A door system comprising:
a revolving door;
a controller for controlling the door;
a door motor operatively connected to the controller;
a first object sensor operatively connected to the controller and configured to detect a presence of an object; and
an operation sensor operatively connected to the controller and configured to detect movement of the door, and
wherein the controller is configured to send an operation signal to the door motor to cause the door motor to operate in response to the controller receiving both:
a signal from the first object sensor indicating that the first object sensor has detected the presence of the object; and
a signal from the operation sensor indicating that the operation sensor has detected the movement.

12. The door system of claim 11 , further comprising a second object sensor operatively connected to the controller and configured to detect the presence of the object, wherein the controller is configured to send the operation signal to the door motor to cause the door motor to operate when the controller detects both:
a signal from the second object sensor indicating that the second object sensor has detected the presence of the object; and
a signal from the operation sensor indicating that the operation sensor has detected the movement.

13. The door system of claim 11 , wherein the operation sensor is a torque sensor that is configured to detect rotational movement of a shaft operatively connected to the door.

14. The door system of claim 11 , wherein the operation sensor is configured to sense movements associated with the door.

15. A method of controlling a revolving door comprising:
providing a controller;
configuring a door motor to be operatively connected to the controller;
operatively connecting a first object sensor to the controller and to detect a presence of an object;
configuring an operation sensor to be operatively connected to the controller and to detect movement of the door, and
configuring the controller to send an operation signal to the door motor to cause the door motor to operate in response to the controller receiving both:
a signal from the first object sensor indicating that the first object sensor has detected the presence of the object; and
a signal from the operation sensor indicating that the operation sensor has detected the movement.

16. The method of claim 15 , further comprising:
configuring at least one second object sensor to be operatively connected to the controller and to detect the presence of the object; and
configuring the controller to send the operation signal to the door motor to cause the door motor to operate when the controller detects both:
a signal from any one of the at least one second object sensor indicating that the one of the at least one second object sensor has detected the presence of the object; and
a signal from the operation sensor indicating that the operation sensor has detected movement.

17. The method of claim 15 , further comprising configuring the operation sensor to sense movements associated with the door.

18. The method of claim 15 , further comprising mounting the first object sensor to a door frame.

19. The method of claim 15 , further comprising configuring the first object sensor to detect the presence of the object in an entranceway of a door system.

20. The method of claim 15 , operatively connecting the door motor to the revolving door.
