The sensor circuit may be configured to generate sensor signals indicative of a position of the covering material. The control circuit may be configured to determine a present sensor state of the sensor circuit, determine a predicted sensor state for the sensor circuit based at least in part on a power-down position recorded at a first time and a final position recorded at a second time, compare the predicted sensor state with the present sensor state, and determine a present position of the covering material based on the comparison of the predicted sensor state and the present sensor state. Methods of adjusting a position of a covering material of a motorized window treatment also are disclosed.

The present disclosure relates to an apparatus for controlling a door drive comprising a path-measuring apparatus for the sensing of a door position and/or a door drive position and for the emitting of a corresponding door position signal as well as comprising a control device for the control of the door drive in dependence on an absolute value of the door position signal and at least one reference point. In accordance with the present disclosure, the apparatus for controlling a door drive is characterized in that the path-measuring apparatus is made with at least two channels and comprises an absolute value encoder for the emitting of an absolute value signal on a first channel and a reference value encoder for the emitting of a plurality of reference point signals on a second channel, and the control device distinguishes a respective reference point signal from other reference point signals using the associated absolute value signal and controls the door drive starting from a specific reference point.
摘要:
A system for operating a barrier system such as a garage door, gate or fence. A DC motor is connected to and operates a barrier drive. A power amplifier is configured to receive power signals from a power supply and to output modulated DC signals to the DC motor. A controller implements an intelligent closed-loop motion control algorithm to control the power amplifier according to a non-linear motion profile. A feedback sensor provides status signals to the controller to determine position or speed of the barrier.

A method of controlling a motorized window treatment provides for continued operation of the motorized window treatment during an overload condition, a low-line condition, or an electrostatic discharge (ESD) event. The motorized window treatment is driven by an electronic drive unit having a motor, a motor drive circuit, a rotational position sensor, a controller, and a memory for storing the command. The controller stores the present position of the motorized window treatment in the memory each time the rotational position of the motor changes by a predetermined angle, such that a plurality of positions are stored in the memory. When the controller is reset due to an overload condition or ESD event, the controller recalls the desired position from the memory, determines the present position, and continues to drive the motor drive circuit in response to the command and the present position.
摘要:
A process for initializing a motorized roller shutter that moves between two extreme positions includes moving the shutter in a first direction at fast speed, then moving it at slow speed, then reversing it in a second direction at fast speed followed by slow speed. The shutter is moved back in the first direction at fast speed, then at slow speed, after which the times are determined that are needed to cover the full travel at fast speed between the two extreme positions in the first direction and in the second direction.

摘要:
A controller for a shutter moved between an opened position and a closed position. A plurality of location ranges is defined between the opened position and the closed position. The controller detects the current moving speed of the shutter in each range, compares the moving speed with a predetermined reference speed, and generates a stop signal based on the comparison result to stop the movement of the drive mechanism.
