Light-control curtain automatic control system

Abstract

The invention discloses a light-control curtain automatic control system. The light-control curtain automatic control system comprises a photosensitive sensor which is used for collecting light intensity of the external environment, a signal correction signal which is used for receiving, and amplifying and filtering the light signal collected by the photosensitive sensor, an A / D converter which is used for converting an analog signal transmitted from the signal correction circuit into a digital circuit, a single chip microcomputer which is used for performing control according to the received digital signal to realize forward rotation, backward rotation and stop of a stepping motor, the stepping motor which is an executing device for controlling on-off of the curtain and performs forward rotation or backward rotation according to the instruction of the single chip microcomputer and a key instruction, a display module which is used for displaying various kinds of states of the curtain control system, and a keyboard module which controls the single chip microcomputer to input instruction through different keys so as to manually control the curtain.

Description

technical field [0001] The invention relates to the field of smart home, in particular to an automatic control system for light-controlled curtains. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's pursuit of living comfort is becoming more and more intense, and curtains are necessary in every family life, and their basic functions are to protect the privacy of residents and shade the sun, etc. .

Problems solved by technology

However, most of the traditional curtains are opened and closed by hand. It is not only labor-saving to open and close every day, but also may miss the best light time, especially for large curtains, which are relatively heavy and long, and require a lot of effort to open and close. Curtains are particularly inconvenient. In response to this phenomenon, electric curtains are produced

The existing electric curtains can basically be controlled by buttons to automatically open and close the curtains. Although it saves effort, the design in some aspects is still not humanized enough.
