The invention provides a control device of an electric push rod and furniture. The control device of the electric push rod comprises an alternating current relay control circuit (1), an electric pushrod control circuit (2), an electric push rod control interface circuit (3), and a laser radar signal reception judging circuit (4), wherein the electric push rod control circuit (2) controls the motion of the electric push rod through the electric push rod control interface circuit (3) according to input signals. According to the control device of the electric push rod, by adopting the structureof an alternating current relay circuit, the ordinary household switch connection and the Internet of things household switch connection are solved. By adopting the structure of laser radar and a controller, the problem that products such as electric forward turning bed or side turning bed cannot stop actively when encountering obstacles (children, the elderly and pets) is solved.
