Description

Combined smart curtain

technical field

The invention relates to a combined intelligent curtain.

Background technique

At present, curtains have become a necessity in people's work and life, and every window is equipped with curtains to block strong sunlight and create a better indoor environment. We need to open and close the curtains at least once a day.

With the increasingly fast pace of life today, people will ignore the change of indoor light because they are absorbed in some things, and people need to open or close the curtains by themselves. In addition, with the continuous development of smart homes, human life has become more and more intelligent, and the original curtains can no longer meet human needs.

For example, in hot summer, especially when people take a break at noon, they need a relatively dark environment. If the curtains are opened, the outdoor sunlight will be irradiated strongly, which will affect people's rest; Therefore, a single curtain cannot meet people's needs.

In the prior art, although smart curtains have also appeared, there are still some problems, such as, the opening and closing of the curtains cannot be controlled remotely; there is only one photosensitive element, the sensitivity is not enough, and it is easy to be interfered by external factors; and It is impossible to flexibly control the stop of the motor, and it is very easy to cause the sensor to hit the wall and be damaged due to the failure of the motor to stop in time, and so on.

Contents of the invention

The present invention is made to solve the above problems, and the purpose is to provide a combined intelligent curtain that can automatically open or close the curtain according to the collected indoor light intensity and outdoor light intensity in different time periods.
