Background technique

Smart home is an efficient, comfortable, safe, convenient and environment-friendly living environment based on the residence as a platform, combining construction, network communication, information appliances, equipment automation, and integrating systems, structures, services, and management. Smart home connects various devices in the home (such as audio and video equipment, lighting system, curtain control, air conditioning control, security system, digital theater system, network appliances, and three-meter copying, etc.) through the Internet of Things technology to provide home appliance control. , lighting control, curtain control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, and programmable timing control and other functions and means. Compared with ordinary homes, smart homes not only have traditional living functions, but also provide a comfortable, safe, high-grade and pleasant family living space; they have also transformed from the original passive static structure into dynamic and intelligent tools, providing a full range of information interaction functions , to help families maintain smooth communication with the outside world, optimize people's lifestyles, help people effectively arrange time, enhance the safety of home life, and even save money for various energy costs. There are many research aspects for smart homes, but what people care most about is the organic combination of safety and comfort.

The life of modern people is busy, due to reasons such as going out to work, there is often no one at home. If the owner fails to close the window when leaving, it may cause criminals to take the opportunity to invade, or damage indoor property due to sudden rainfall. In order to overcome this problem, there are currently many solutions to automatically close the window sash, such as the patent "A New Type of Automatic Anti-theft Window" with the authorized announcement number of 201297105. On the side of the frame, there are fastening screws on the glass support, and several motors are respectively installed in the middle of the upper and lower ends of the glass, and the several motors are respectively connected with each roller, and each roller is set on its own slideway. A left controller and a right controller are respectively arranged under the two sides of the window frame, and a control module is arranged on one side of the right controller, which can facilitate anti-theft control; there is also a patent application with a publication number of 102465644A "automatically closing the rainproof window" , including windows, sponge materials, toothed metal strips and gear motors, sponge materials are installed on the lower part of the window, the sponge materials are connected to the working circuit of the electromagnetic relay installed indoors through wires, toothed metal strips are installed on the upper part of the window, and the gear motor is connected to the indoor The working circuit of the installed electromagnetic relay is connected and can drive the toothed metal bar to move. Due to the above structure, when it rains, the rainwater is sucked by the sponge material. Since the rainwater is a conductor, the working circuit of the electromagnetic relay is connected, and the gear motor drives the toothed metal strip to move, and the window is closed to prevent rainwater from floating into the room. Purpose. But above-mentioned technical solution is aimed at anti-theft and anti-rain problem, but can not meet the demand in order to improve the living comfort of the owner in smart home. For example, the owner feels that the room is hotter before resting, and opens the window for ventilation, but the temperature drops after falling asleep, and the owner cannot find out in time and close the window, which will cause the owner to catch a cold. In addition, the opening direction of ordinary windows is determined when the house is built. When the opening direction of the bedroom window faces the bed, it is easy to make the owner who is resting suffer from the cold due to direct exposure to the wind.

If the body surface temperature is still lower than If the threshold is set, the single-chip microcomputer continues to drive the motor to rotate until the sash is completely closed.

When the body surface temperature of the house owner collected by the infrared thermometer is higher than the second set threshold, the single-chip microcomputer sends a signal to drive the motor to rotate, changing the direction of opening the window sash, and if the body surface temperature is still higher than the second set threshold after the set period threshold, then the single-chip microcomputer continues to drive the motor to rotate until the sash is fully opened; the second set threshold is higher than the set threshold.

The installation positions of the infrared thermometer include the head, the middle and the tail of the bed, wherein the body surface temperature collected in at least one position is lower than the set threshold or the body surface temperature collected in at least two positions is higher than the second set threshold , the microcontroller sends out a signal.

The beneficial effects of the present invention are: the present invention prevents the owner of the house from getting cold due to excessive ventilation by collecting the indoor temperature. The present invention adopts an infrared thermometer to collect the body surface temperature of the house owner instead of an ordinary thermometer, and considers the temperature reduction caused by the cold wind taking away the water on the body surface of the house owner. The present invention collects the temperatures at the head, middle and end of the bed respectively, and fully considers the influence brought by the owner of the house covering the body surface with bedding or clothing. The invention also adopts steel bars or induction wires, taking into account the anti-theft function.
