[0002] With the improvement of the material living quality of modern people, people begin to yearn for smart home. Related technologies such as smart windows and smart curtains have attracted more and more attention. The opening and closing of traditional windows are manually controlled. When sudden weather changes occur, such as sudden rain or wind, the windows cannot be closed in time. Secondly, it is also difficult to close windows manually for high-rise or large windows. With the mature development of single-chip microcomputers and sensors now, such technologies can be applied to the field of windows. The inventor searched and found that most window technologies mainly focus on electric windows. For example, patent publication number CN1786403A records an electric window. These windows do not require manual opening and closing of the window sashes, only solving the problems existing in manual opening and closing. There is no mature technology for remote control and judging the opening and closing state of the window according to the weather and environment, as well as the corresponding opening and closing angles of the window.

[0019] The following further describes the present utility model with reference to the drawings:

[0020] Embodiment: As Figure 1-8 shown, a casement window control device includes a casement window body including a window frame and a window sash. An opening mechanism is installed between the window frame and the window sash. The opening mechanism is used to realize the opening and closing of the window sash and its opening and closing angle. The opening mechanism includes a controller, a swing arm 2, and a guide rail 3. The controller 1 includes a housing. A stepping motor, a power supply, and a microcontroller are placed inside the housing. One end of the swing arm is hinged to the output end of the stepping motor, and the other end of the swing arm is hinged to a slider 4. The slider moves within the guide rail. The input end of the microcontroller is respectively connected to a key, a smoke sensor, a rain drop sensor, and a wind speed sensor. The rain drop sensor and the wind speed sensor are both installed on the outer surface of the window sash, for example, on the frame of the window sash, that is, the frame is designed with a placement area or a placement groove corresponding to the sensors. The rain drop sensor 12 and the wind speed sensor 13 are installed in the placement area or the placement groove. The data line and the power line are connected to the microcontroller and the power supply inside the controller along the frame. The output end of the microcontroller is connected to a stepping motor driver, a buzzer, and a display screen. The motor driver is used to drive the stepping motor. The microcontroller communicates with a control terminal through a communication module. Similarly, a placement area or a placement groove is designed on the inner surface of the window frame. A single-chip microcomputer 5, a buzzer 6, a display screen 7, an LED lamp 9, a smoke sensor 10, a switch 8, and a WIFI module 11 are installed in the placement area or the placement groove. The power supply is used to supply power to the entire device.

[0021] In the above embodiment: The microcontroller uses an STM32 microcontroller, the communication module uses a WiFi module ESP8266, the display screen uses an OLED display screen, the rain drop sensor uses a YL-83 rain drop sensor for monitoring outdoor rain drop signals, the wind speed sensor uses a ZTS-3000-FSJT polycarbonate wind speed sensor for monitoring outdoor wind speed signals including wind speed and wind grade, and the smoke sensor uses an MQ-2 smoke concentration sensor for monitoring indoor smoke.

[0022] Similarly, the above MQ-2 smoke concentration sensor can also be installed in the placement area or the placement groove on the outer surface of the window frame for monitoring outdoor smoke conditions, and the control device closes the window according to the smoke conditions.

[0023] In the above embodiment: The housing of the controller is fixed to the window frame by screws, and the guide rail is fixed to the window sash by screws.

[0024] In the above embodiment: One side of the window sash is rotatably connected to the window frame through a hinge.

[0025] In this embodiment, two modes are designed. In the manual mode, the casement window is the same as the traditional window and relies on manual operation to open and close the window. In the automatic mode, the casement window depends on the data signals detected by various sensors to open and close the window. Threshold requirements are preset for the controller. If the signals obtained by the smoke sensor, raindrop sensor, and wind speed sensor meet the set requirements, the single-chip microcomputer sends a signal to the actuator to close the window. In terms of intelligent interaction, a WIFI module is selected to connect to the network, and data can be received and sent through the OneNET cloud platform. The mobile phone APP can receive real-time sensor data and remotely operate through the mobile phone.

[0026] The opening and closing actions are realized by the window opening mechanism, which consists of a stepper motor, a reduction mechanism, a swing arm, a guide rail, etc. The output part of the stepper motor meshes with multiple gears through a gear. There is a hole on the gear shaft for positioning in the shell. The last-stage gear cooperates with the coupler. The adapter of the window opening swing arm cooperates with the coupler. The window opening swing arm and the window opening swing arm coupler are connected by bolts to realize the hinged rotation function. A common window opening limiter swing arm on the market is adopted. A hole is drilled at its end and connected to the adapter with screws. The other end cooperates with the slide rail cylinder adapter on the guide rail.

[0027] The specific operation process of the control system is as follows:

[0028] After the system is powered on and running, the system and each sensor will be initialized. After the WIFI module is connected to the network, the sensors start to monitor the outdoor environment signals;

[0029] The STM32 microcontroller reads the wind speed information monitored by the environmental wind speed sensor module and judges whether the wind speed exceeds the set value; reads the outdoor raindrop signal monitored by the raindrop sensor module to determine whether it is raining outdoors; reads the outdoor smoke concentration signal monitored by the smoke sensor module and judges whether it reaches the set standard; to determine whether the system implements the actions of opening and closing the window.

[0030] After the STM32 microcontroller processes and converts the relevant data, it controls the OLED display screen to display the real-time data of each sensor. The WIFI communication module connects to the cloud platform through the set network and uploads the real-time collected data to the OneNET cloud platform client, and then realizes remote communication with the window, so as to remotely view the relevant environmental information and window status through the mobile phone application.

[0031] The mobile phone APP inputs instructions to the system through the artificial client of the OneNET cloud platform. Then the system continuously searches the WIFI module repeatedly to check whether there are new instructions from the OneNET cloud platform. When a new instruction is received, the STM32 controls the operation of each functional module of the entire system.

[0032] The operation mode of the window can be adjusted through the button function, which is divided into manual and automatic gears. The automatic gear relies on the signals monitored by each sensor to open and close the window. When switched to the manual mode, it can only be controlled by the manual opening and closing window instructions.

[0033] The above are all preferred embodiments of the present invention. For those of ordinary skill in the art, without departing from the principle of the present invention, the modifications of various equivalent forms of the present invention all fall within the protection scope of the appended claims of this application.
