Abstract
A door monitoring system included a braking system. The present disclosure may include a position sensor that determines a position of a door; a position filter in series with the position sensor to generate a position signal; a speed filter to generate a speed signal from the position signal; an anticipation circuit to determine an anticipated position of the door at a future period based on the position signal and the speed signal; determine, based on the anticipated position, an anticipated speed; and determine whether the anticipated speed exceeds an allowable speed and engage a relay configured to disconnect a drive circuit and connect at least one braking resistor to a motor to slow the speed of the door. In some aspects, the braking system comprises at least one controller for performing one or more of the above steps.
