Abstract

A controller for a garage door of the roller type includes a ring gear 1 which is used to drive the door. A follower gear 5, which is driven from the ring gear, drives a position wheel 3 and cutter wheel 4. The position gear has a series of arcuate projections of different radii on its underside, which may encode a 3 bit gray code. The movement of the projections as the position wheel rotates is detected by opto-interrupters, and this can be related to the position of the door. The speed of the door is detected by cutter wheel 4 as teeth on the wheel pass an optical sensor. Output from the position wheel and cutter wheel is used to control the door so that it stops at the limits of its travel, and will stop if door movement is prevented by an obstruction.
