Abstract

The present disclosure includes systems, methods, and articles of manufacture for controlling a door. In various embodiments, exemplary systems may include a controller that may initialize and/or reset a limit count. A controller may initialize and/or reset a limit count in response to detection by a first position sensor of a first target. A controller may further initialize and/or reset a limit count by incrementing the limit count in response to a signal from a gear tooth sensor until a second position sensor detects a second target, whereupon the controller may store the limit count.

Claims (63)

1. A system comprising:

a controller for controlling a door,

a tangible, non-transitory memory configured to communicate with the controller,

the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising:

receiving, by the controller, a limit setting input;

translating, by the controller and via an operator comprising one or more motors, the door to a first position in response to the receiving the limit setting input;

detecting, by a first position sensor in communication with the controller, a first target on the door in response to the door reaching the first position;

receiving, by the controller and from the first position sensor, a first signal indicating the detection of the first target;

translating, by the controller and via the operator, the door from the first position to a second position;

detecting, by a second position sensor in communication with the controller, a second target on the door in response to the door reaching the second position;

receiving, by the controller and from the second position sensor, a second signal indicating the detection of the second target;

receiving, by the controller, a measured count from a gear tooth sensor, wherein the measured count is a number of detected gear teeth counted by the gear tooth sensor during the translation of the door from the first position to the second position;

setting, by the controller, a limit count based on the received measured count;

translating, by the controller and via the operator, the door from a third position to at least one of the first position or the second position;

translating, by the controller and via the operator, the door from the at least one of the first position or the second position to at least one of the second position or the first position;

receiving, by the controller, a second measured count from the gear tooth sensor in response to the translation of the door from the at least one of the first position or the second position to the at least one of the second position or the first position;

comparing, by the controller, the limit count to the second measured count;

determining, by the controller, whether the limit count matches the second measured count; and

calculating, by the controller, a relative position of the door based upon the comparison of the limit count to the second measured count.

2. The system of claim 1 , wherein the operations further comprise storing, by the controller, the limit count in response to setting the limit count.

3. The system of claim 1 , wherein the operations further comprise:

resetting, by the controller, the limit count in response to the limit count differing from the second measured count.

4. The system of claim 1 , wherein the operations further comprise monitoring, by the controller, an operational status of at least one of the controller or the door.

5. An article of manufacture for controlling a door, including a non-transitory, tangible computer-readable memory having instructions stored thereon that, in response to execution by a controller, cause the controller to perform operations comprising:
