Low cost, low power consumption radio frequency transceivers are incorporated in barrier operator control systems for transmitting signals between an operator control unit, one or more remote control units, a diagnostic or calibration device and an obstruction detector. Similar detector devices, including such transceivers, may be employed in loading docks for detecting the status of dock levelers and vehicle restraint devices. Radio frequency communication eliminates the need for hard wiring and also provides for transmission of commands and status information between various control units.
In a barrier operator system for moving a barrier between open and closed positions, a motor operably connected to a mechanism connected to said barrier, a base controller operably connected to said motor and operable to receive signals from barrier position limit detection means, and at least one remote control unit operable for wireless communication with said base controller, the improvement characterized by:
In a movable barrier operator system including a base controller having a radio frequency base transceiver and a remote control unit for controlling movement of said barrier, said remote control unit including a radio frequency remote transceiver operable to communicate with said base transceiver, a method including the steps of:
In a barrier operator system for moving a barrier between open and closed positions, a motor operably connected to a mechanism connected to said barrier, a base controller operably connected to said motor and operable to receive signals from barrier position limit detection means, at least one remote control unit operable for wireless communication with said base controller, at least one of a barrier status indicating unit and an obstruction detection unit operable for wireless communication with at least one of said base controller and said at least one remote control unit;
In a barrier operator system for moving a barrier between open and closed positions, a motor operably connected to a mechanism connected to said barrier, a base controller operably connected to said motor and operable to receive signals from barrier position limit detection means, at least one remote control unit operable for wireless communication with said base controller, at least one of a barrier status indicating unit and an obstruction detection unit operable for wireless communication with at least one of said base controller and said one remote control unit;
In a loading dock, including a dock leveler and at least one vehicle restraint disposed adjacent said dock leveler, said vehicle restraint and said dock leveler including, respectively, detector units associated therewith for transmitting radio frequency signals to a transceiver and control unit indicating the status of said vehicle restraint and said dock leveler, respectively, and a master, control unit operably connected to respective control units for said vehicle restraint and said dock levelers transmitting radio frequency signals to indicate the status of each of said vehicle restraints and said dock levelers, respectively and wherein said detector units are operable between a lower power consumption mode until a change of status signal is provided from the control unit to the detector units, wherein in response to said change of status signal, said detector units operate in a higher power consumption mode.
In a barrier operator system for moving a barrier between open and closed positions, a motor operably connected to a mechanism connected to said barrier, a base controller operably connected to said motor and operable to receive signals from barrier position limit detection means, and at least one remote control unit operable for wireless communication with said base controller, the improvement characterized by:
