Abstract
A monitoring system (100) for an overhead door arrangement (10), wherein the overhead door arrangement (10) comprises a door leaf (11), comprising a plurality of door panels (17a-f), being movable between a vertical closed position and a horizontal, opened or overhead position within a side frame (16), wherein the movement is caused by an operating system (20) comprising at least one motor (28) and a drive arrangement (25) connected to the motor (28) and at least one of the door panels (17a-f), and wherein the door leaf (11) is balanced by means of a counter balancing mechanism (70) connected to the door leaf (11) and comprising a balancing shaft (73) and one or more balancing springs (71, 72).
Claims23
A monitoring system (100) for an overhead door arrangement (10), wherein the overhead door arrangement (10) comprises a door leaf (11), comprising a plurality of door panels (17a-f), being movable between a vertical closed position and a horizontal, opened or overhead position within a side frame (16), wherein the movement is caused by an operating system (20) comprising at least one motor (28) and a drive arrangement (25) connected to the motor (28) and at least one of the door panels (17a-f), and wherein the door leaf (11) is balanced by means of a counter balancing mechanism (70) connected to the door leaf (11) and comprising a balancing shaft (73) and one or more balancing springs (71, 72),
- wherein the monitoring system (100) comprises:
- a controller (120),
- a load sensing device (110) operatively connected to the controller (120) and configured to acquire load data associated with the counterbalancing torque provided by the counter balancing mechanism (70), whereby the controller (120) is configured to obtain said load data.
A method (5000) for operating an overhead door system (1000),
- wherein the overhead door system (1000) comprises:
- an overhead door arrangement (10), wherein the overhead door arrangement comprises a door leaf (11) comprising a plurality of door panels (17a-f) being movable between a vertical closed position and a horizontal, opened or overhead position within a side frame (16) and an operating system, wherein the movement is caused by the operating system (20) comprising at least one motor (28) and a drive arrangement (25) connected to the motor (28) and at least one of the door panels (17a-f), the overhead door arrangement (10) further comprising a counter balancing mechanism (70), wherein the door leaf (11) is balanced by means of the counter balancing mechanism (70) and said counter balancing mechanism is connected to the door leaf (11) and comprises a balancing shaft (73) and one or more balancing springs (71, 72),
- and a monitoring system (100), wherein the monitoring system (100) comprises a controller
(120) and a load sensing device (110) operatively connected to the controller (120) and configured to acquire load data associated with the counterbalancing torque provided by the counterbalancing mechanism (70), whereby the controller (120) is configured to obtain said load data,
- wherein the method comprises:
- acquiring (5001) load data associated with the counterbalancing torque provided by the counterbalancing mechanism (70), and
- causing (5003) operation of the overhead door arrangement (10) based on said load data.
