Movable barrier operator with signal translation module

摘要

The present invention is generally a movable barrier system that employs a movable barrier operator with a signal translation module, which enhances the quality of communications between wired components of a movable barrier system, including long distance wired communications between controllers and position sensors. In an exemplary embodiment, position sensors comprising encoders are coupled to translation module for reducing electromagnetic interference or noise from various components that may otherwise interfere with the communication; error detection and error correction means may be further implemented to facilitate diagnostic monitoring of the system from a monitoring device.

主权项

1. A movable barrier operator, comprising:
a first module, including: a motor configured to move a barrier; one or more sensors for generating one or more signals concerning one or more parameters of the barrier; and a first translation module for reducing electromagnetic interference, wherein the first translation module is configured to:
receive the one or more signals,generate a differential signaling transmission concerning the one or more signals, andtransmit the differential signaling transmission concerning the one or more signals to a control board; anda second module situated remote from and in wired communication with the first module, the second module comprising the control board and including:a second translation module configured to receive, from the first module, the differential signaling transmission concerning the one or more signals, and a controller situated at the control board, the controller configured to:
generate data concerning the one or more signals, andprovide the data concerning the one or more signals via a user interface.
