摘要:
A fixed position remote control unit (20) as used with a movable barrier operator (11) has an externally accessible plug-in module interface (25). This interface (25) operably couples to the link (23 and 24) between the remote control unit (20) and the operator (11). So configured, a plug-in module (40) that docks and couples with this plug-in module interface (25) can receive operating (or charging) power from the movable barrier operator (11), exchange signaling with the movable barrier operator (11), or both. The ability to readily exchange signaling without invasive wiring permits a wide variety of plug-in modules (40) to be utilized.
摘要:
A barrier mount system which opens and closes a barrier such as a gate or garage door (14) in response to user generated commands. An obstruction detection apparatus (34, 90, 110, 122) is provided for safety of operation. When an obstruction is sensed, the barrier movement system is inhibited from responding to user generated commands until a predetermined event occurs. The event may be passage of a predetermined amount of time or barrier movement of a particular amount.

Appareil (10) d'ouverture et de fermeture de porte de garage à sécurité de fonctionnement améliorée. Ledit appareil comprend un circuit de commande (101) qui réagit à un certain nombre de stimuli d'entrée pour générer des commandes d'ouverture et de fermeture d'une porte de garage (14), ainsi que d'arrêt du mouvement de la porte de garage. Trois relais (130, 131, 132) réagissent aux commandes par l'intermédiaire de circuits d'entraînement (147) afin de connecter effectivement des tensions de fonctionnement de porte aux bobinages (225, 227) d'un moteur de commande de porte (24). Grâce à des redondances dans le fonctionnement de ces trois relais, des défauts de fonctionnement desdits relais aboutissent à des conditions sûres de fonctionnement de la porte. En outre, lorsqu'une commande d'arrêt de la porte est émise, le circuit de commande effectue un test afin de déterminer si la porte est encore en mouvement ou non. Si la porte est encore en mouvement, des commandes de levage de porte sont générées par le circuit de commande afin de placer la porte dans une position de sécurité.
摘要:
An electronic service reminder to automatically notify a user to when and what type of maintenance should be performed on the garage door operator (10), based on a variety of factors, including time, materials and operating environment. The garage door operator (10) is configured to automatically generate an electronic service reminder in the form of an audible (130) or visual alert (126) based on one or more operating parameters of the garage door operator (10) meeting or exceeding a predefined threshold. The predefined threshold is variable based on the values of the operating parameters.
摘要:
A method and apparatus for controlling a barrier movement operator comprising a controller (18) that dynamically controls barrier operator braking to electronically slow, stop or reverse the motor in the barrier operator controller. The apparatus includes a source of electrical power (10) for providing the necessary power to operate the apparatus, a converter (14) for supplying power to a DC motor (16), and a controller for enabling dynamic braking of the movable barrier operator using electronic braking of the electric motor. The dynamic braking of the motor gradually slows movement of the barrier operator, thereby reducing forces acting on the motor and on the barrier.
摘要:
A method and apparatus for controlling power supplied to a motor (60), comprising a power controller (58) having a source of electrical power (52) for providing the necessary power to operate the apparatus (50), an oscillator (56) for generating gating signals at a relatively higher frequency than the electrical power supplied, circuitry responsive to the gating signals for gating the low frequency electrical power to generate a DC voltage, and an inhibitor for inhibiting the generating of gating signals by the oscillator (56) to regulate the DC voltage generated so as to control the speed of any motor connected to the apparatus. The apparatus may be setup to inhibit the oscillator when certain circuit conditions such as an over current condition is detected. The apparatus may also be setup to keep the oscillator in an OFF state once inhibited until a specified amplitude or a period of the input signal has been reached.
摘要:
Methods and apparatus for controlling an automatic barrier movement system, particularly for beginning movement (316) of a barrier which has been stopped (305) between an open and closed position of the barrier. The receipt of a barrier movement command will generally start movement of the barrier toward the open position, (317) however, when predetermined conditions (321,325) are met the barrier may be started in a direction determined by a preprogrammed algorithm (325). The predetermined conditions (321,325) may include that the barrier has been stopped for less than 5, minutes (321) and/or that the barrier was stopped in response to an obstruction during travel toward the open position. The preprogrammed algorithm (325) may be to move the barrier toward the closed position (327) or move the barrier in a direction determined from other sensed conditions.
摘要:
In a multiple barrier movement operator environment (Fig. 2), one switch module (339) for controlling all of the barrier movement operators. The switch module (339) may be mounted for convenient and communicates with the barrier operator either wirelessly or through a wired interface. The switch module (339) controls and operates movement of any barrier singly while controlling the operation of the overhead light and response inhibit modes of all the barrier operators. A stop button (239) also maybe provided to enable all the barrier operators to discontinue movement of their respective barriers.
摘要:
In a control system (10) having a learning mode (20) such that performance limits can be automatically determined for subsequent use during normal operating modes (40), one or more user manipulable controls (18) are provided to allow a user to selectively adjust the previously automatically determined performance limits. In one embodiment the range of adjustment can be limited. The user control (18) can be located in various positions with respect to the control unit (15). In an exemplary embodiment, the control system (10) comprises a movable barrier operating system such as a garage door opener.
摘要:
A garage door opening and closing apparatus (10) having improved operational safety is diclosed. The apparatus includes a control circuit (101) which responds to a number of input stimuli to generate commands to open and close a garage door (14) as well as to stop garage door movement. Three relays (130, 131, 132) respond to the commands via drive circuitry (147) to actually connect door operating voltages to the windings (225, 227) of a door controlling motor (211). By redundancies in the operation of the three relays, faults in the operation of those relays result in safe door operating conditions. Additionally, the control circuitry upon issuing a door stop command, performs a test to determine whether or not the door is still moving. If the door is still moving, doorup commands are generated by the control circuitry to place the door in a safe position.
