Barrier Operator Strain Detection

摘要

A barrier sensor device and associated control device monitor operation of a barrier operator system. The barrier sensor device monitors operation of barrier operators for undesirable amounts of strain without barrier operator force as an input. The barrier sensor device instead detects both motion and tilt of a barrier. By monitoring these two aspects of barrier operation, the barrier sensor device compiles data that can be analyzed by the control device and compared to un-strained or previously compiled barrier operator data to determine whether the barrier operator system is under strain and requires service.

主权项

1. A retrofit monitoring apparatus for a movable barrier system, the apparatus comprising:
one or more sensing devices configured to be secured to a movable barrier driven by a movable barrier operator and to obtain position and movement data of the movable barrier; a control device remote from the movable barrier operator and configured to be in communication with the sensing devices, the control device configured to:
receive the position and movement data;compare the position and movement data to target operational data; andgenerate a service signal in response to comparing the position and movement data to the target operational data.
