A garage door status monitoring and control system includes a motor operable to move a garage door to alternate garage door positions, an encoder associated with the motor and configured to generate a pulse stream comprising motor signal pulses indicative of movement of the motor, a door control module with a first microprocessor operatively coupled to the encoder via a first path and configured to receive the pulse stream, and a garage door operator having a door controller with a second microprocessor operatively coupled to the encoder via a second path and configured to receive the pulse stream from the encoder independent of the door control module. The first microprocessor is configured to generate a digital door status indicative of one of the alternate garage door positions in response to the pulse stream. The garage door operator provides supervisory control over movement of the motor based upon the pulse stream.

Remote monitoring and control of movable barrier status

Movable barrier monitoring apparatus and methods are provided for rapidly responding to barrier travel obstructions and other abnormal occurrences to cause the movable barrier operator to halt barrier travel or stop and reverse barrier travel, while ignoring typical and normal impediments to barrier travel. Alternate methods are described for programming the barrier operator controller to compare characteristics of the monitored barrier run over the defined travel path with the characteristics of a good barrier run without interruption to barrier travel, with the degree of differentiation of such characteristics determinative of whether the operator controller is to interrupt barrier travel or not.

Movable barrier apparatus and methods for responding to barrier travel obstructions and abnormalities

A garage door status monitoring and control system includes a control module for receiving door position information and receiving change of door position commands from a remote Internet access device. The control module includes a programmable platform configured to: route door position information to a wireless interface for transmission to the Internet access device; and cause said change of door position commands to generate a light and sound command and a door position command. A Bluetooth microprocessor generates a wireless signal to actuate a light fixture in response to the light and sound command. The light fixture includes a microprocessor for wirelessly returning an acknowledge signal. The acknowledge signal is conductively transmitted to the programmable platform from the Bluetooth microprocessor. Receipt of the acknowledge signal allows the door position command to be generated only after a defined period of time following the generation of the light and sound command.

Remote monitoring and control of garage door opener incorporating jackshaft door operator drive assembly

A garage door status monitoring and control system for a jackshaft operator may include a control module comprising a programmable platform configured to: receive a change-door-status command to change a position of a door; in response to the change-door-status command, generate and communicate a light or sound command to a wireless controller; delay a period of time after communicating the light or sound command to the wireless controller; and only after the delay, generate a door command corresponding to said change-door-status command to change the position of the door.

Remote monitoring and control of moveable barrier in jackshaft door operator system

Disclosed herein is an access control apparatus for a barrier movement system that moves a barrier. The access control apparatus includes a near field communications (NFC) module, a radiofrequency (RF) module, and a controller coupled to the NFC module and RF module. The controller is configured to read an NFC signal from an authenticated external device, via the NFC module. In response to reading the NFC signal, the controller transmits a command signal, via the RF module, that commands the barrier movement system to move the barrier.

Near field communications activated door access panel

A system for moving a barrier includes a motor with an integrated encoder operative to generate pulses as a function of rotation of the rotatable shaft of the motor. A preferred form of encoder is a rotary optical encoder to generate optical pulses as a function of rotational movement of the rotatable shaft. Both a microcontroller to determine door status and a controller to control door movement receive the pulses and separately execute methods in response thereto.

A movable barrier opener system having a brushless DC motor is provided. The movable barrier opener system may have a power supply unit with a drive circuit power module and a storage bank. The storage bank may be chargeable by the drive circuit power module and may be connectable to the drive assembly to provide electrical power to the drive assembly to move the movable barrier. The drive circuit power module may be selectably turned on and off to improve efficiency of power consumption by turning off during periods of lowered demand.

Power supply for movable barrier opener with brushless DC motor

A movable barrier opener system having a multiphase brushless DC motor in the drive assembly is provided. The multiphase brushless DC motor may impart motive force to a movable barrier in response to barrier movement instructions from the barrier operator controller to the drive assembly. The barrier operator controller of the movable barrier opener system is configured to detect a back EMF of at least one winding of the multiphase brushless DC motor and determines a position of the movable barrier and/or determines a torque of the multiphase brushless DC motor in response to the detected back EMF. A position sensor and a back EMF sensor module provides actual operating parameters to the controller.

Movable barrier opener with brushless DC motor

A controller for a door operator including a processor, a first actuator, and a transmitter, and associated method. The method may include inverting bit positions of a rolling code, dividing the inverted code by a predetermined number, converting the divided inverted code to base 9 coefficients, and substituting an output nibble for each base 9 coefficient in the divided converted code. The transmitter may be configured to transmit the substituted output nibble responsive to actuation of the first actuator.

Universal barrier operator transmitter

Systems and methods for controlling a moving barrier responsive to a transmission by a barrier operator controller comprising a plurality of 4-bit output nibbles generated from a 32 bit rolling code. The bit positions of the rolling code are inverted, divided by 16, converted to four bit base 9 coefficients, each four bit base 9 coefficients is substituted with a corresponding 4-bit output nibble. Receipt of the plurality of 4-bit output nibbles causes a barrier operator to actuate a motor connected to the moving barrier.

An Internet based system for remotely monitoring and changing the open/closed door status of a garage door. A position detector is coupled to the door. Two position detectors, preferably substantially orthogonal with respect to one another, determine the barrier status. A wireless transmitter transmits the barrier status to a multi-functional control module. The control module also receives a change of status command from the Internet Cloud to move one or more doors in accordance with the command. Multiple relays paired with the doors allow the control module to control a plurality of doors.

Remote transmission of barrier status and change of status over a network

A system for enabling both the remote monitoring and receipt of remote change-of-door status commands, via the Internet, of the open or closed status of the garage door. The system includes an encoder generating signal pulses as a function of the motor and garage door movement. A microprocessor processes the signal pulses to generate digital pulses indicative of the open or closed status of the garage door, which status is wirelessly transmitted, via the Internet, for remote monitoring. Change-of-door status commands remotely transmitted, via the Internet, are received by the system to activate a warning and delayed change of door status.
