ABSTRACT:
Disclosed is a radio controlled clock movement control system, including two stepper motors, two gearings, and a photo electronic control unit. The two stepper motors are operated independently each one driving a gearing, where the first gearing contains a second wheel, and the second gearing contains an hour wheel and a minute wheel. The photo electronic control unit contains a first photo detector, a second photo detector, and a light source. Multiple through holes are formed in succession over one sector near the rim of the second and minute wheels, which are moved in the direction of rotation over the photo detectors that undertakes to check the minute and second wheels for the zero alignment. Therefore, a radio controlled clock having the present clock movement control system can be self reset in a fast manner.
