System and methods for automatically moving access barriers initiated by mobile transmitter devices

摘要

An operator system and related methods for automatically controlling access barriers which includes a base controller associated with at least one access barrier and at least one base receiver associated with the base controller. The system also includes at least one mobile transmitter that automatically and periodically generates at least one mobile signal detectable by the base receiver. The base controller selectively generates barrier movement commands upon receipt of the at least one mobile signal. Timers may be used to block receipt of any mobile signals for a period of time to prevent any further door movement. Such a system allows for hands-free operation of the access barrier. A discrete processing system may also be used to retrofit existing barrier operator systems for use in hands-free operation.
