Description

a smart window

technical field

The invention relates to a window, in particular to a smart window, which belongs to the technical field of smart home.

Background technique

With the rapid development of Internet of Things technology, smart home decoration has become an important part of the development of family informatization and social informatization. Smart home is also called smart house. When connected together, a modern smart home system with powerful functions and high intelligence is formed. Smart home emphasizes people-oriented, pays attention to the coordination between people and the living environment, and can control the living environment at will to a certain extent. The application of smart home control system enables people to enjoy a comfortable, safe and convenient life at home, and the living environment is more in line with environmental protection requirements.

Many household electrical appliances such as color TVs, refrigerators, air conditioners, etc. have been labeled with intelligent labels, and have made great contributions to the improvement of people's quality of life. But it is a pity that the eyes of the living room - the windows, have not been able to keep up with the pace of the times. Even in many intelligent living quarters, we can find that almost all window management is still in the original management mode, which has nothing to do with intelligence. If the windows have certain intelligence, such as automatically closing the windows when it rains, automatically opening the windows when indoor harmful gases exceed the standard, and automatically alarming when thieves enter, this will bring many conveniences to people's home life, thereby further improving people's health. quality of life and standard of living. In recent years, the emergence of electronically controlled windows has met this demand of people. However, most of the domestic products have relatively separated functions, and the price of similar foreign products is relatively expensive, so it is very necessary to design and research a smart window system.

The seasons change and the weather is unpredictable. People need a smart window that can be closed automatically when it rains or winds suddenly, so as to relieve the worries of people who are busy with work. Although air-conditioning has been gradually popularized in residents' homes, people still feel that air-conditioning wind is far less comfortable than natural wind. In the hot summer, the outside air is relatively stuffy in the first half of the night, and residents need the service of air conditioning, and the outdoor air is relatively refreshing in the second half of the night. Turning off the air conditioner and opening the windows is the best choice. At this time, a smart window is needed to realize automatic switching. functions without destroying people's dreams.

In this embodiment, the raindrop detection circuit adopts a comb circuit, which has a simple structure but can well realize the function of testing raindrops. Every once in a while, the single-chip microcomputer collects the indoor temperature as a sample, and displays the indoor temperature on the display screen. When running into a rainy day, the raindrop detector detects and transmits a control signal back to the single-chip microcomputer, and the single-chip microcomputer controls the first DC motor 5 to automatically close the window. The photosensitive sensor detects the light intensity, and provides control signals for the single-chip microcomputer to control the closing of windows and curtains.

The single-chip microcomputer is loaded with a control program, which can set the time for opening and closing the window. On a sunny morning, the single-chip microcomputer system outputs the forward rotation signals of the first to second DC motors according to the set window opening time, and the first to second DC motors rotate forward. The occlusion of the two gear rods automatically controls the opening of windows and curtains; when the sun sets in the evening, according to the set time, the first to second DC motor reverse signals are output, the first to second DC motors reverse, and the first to second The gears are respectively engaged with the first to the second gear bars, and the windows and curtains are automatically closed. If it rains outside after the window is opened, the raindrop detection circuit detects the rain, and sends a control signal to the single-chip microcomputer, and the single-chip microcomputer outputs the reverse signal of the first DC motor 5, and the window is closed automatically by the engagement of the first gear 7 and the first gear rod 4 , so that the room will not be wet. The temperature detection circuit detects the temperature and sends it to the single-chip microcomputer. After the single-chip processing, the display screen displays the current indoor temperature. The clock chip sends the time information to the single-chip microcomputer. After the single-chip processing, the display screen displays the current time; Switching between automatic control and manual control, when switching to manual control, the windows and curtains can be opened and closed according to the needs of the owner; at the same time, in the manual control state, corresponding control parameters can be set and adjusted according to changes in seasonal climate and temperature standards.

The present invention is especially suitable for owners who are short of time and have no time to open and close windows or ventilate; or there are old people and children at home, and they are unable to open and close windows in time. The smart window system will automatically open the windows every morning and close them in the evening to adjust the indoor temperature and replace the indoor air; the windows can be closed in time even in rainy days, and the current temperature and time can also be displayed at the same time, which can greatly facilitate people's lives and improve the quality of life of residents. The worries of office workers.

The drive circuits of the first to the second DC motors all use double-end input, double-end output, and single-power-supplied bridge push-pull power amplifier circuits as the drive circuit, which effectively synthesizes two half-period signals on the load into a complete Signal. The digital signal transmitted by the single-chip microcomputer 1 is amplified by the power of the triode 8550 and 8050, so as to control the forward and reverse rotation of the first to second DC motors.
