Among them, controller 1 adopts STC12C5A60S2 single-chip microcomputer. The power module 2 adopts a 12V2A switching power supply. Temperature and humidity sensor 3 adopts DHT11 digital temperature sensor. The chip of the real-time clock module 7 adopts DS1302 chip. Liquid crystal display module 9 adopts LCD12864 liquid crystal display screen. The motor drive module 10 adopts the A4988 module.

This device takes STC12C5A60S2 single-chip controller 1 as the core, and consists of power module 2, temperature and humidity sensor 3, wind speed sensor 4, raindrop sensor 5, button module 6, real-time clock module 7, electromagnetic lock 8, liquid crystal display module 9, and motor drive module 10 and stepper motor 11 form. The liquid crystal display module 9 adopts LCD12864 liquid crystal, which has the characteristics of large amount of display information and clear characters; the temperature and humidity sensor 3 adopts DHT11 digital temperature sensor, and the measurement range of this temperature and humidity sensor is humidity 20-95RH, temperature 0-50 ℃; real-time Clock module 7 adopts high-performance real-time clock chip DS1302 with RAM, and has leap year compensation function; motor drive module 10 adopts A4988 module, this special motor drive chip has load circuit protection and short circuit protection functions, and has five optional Mode; power supply module 2 uses 12V2A switching power supply as the working power supply of the electromagnetic lock and motor, and reduces the 12V/2A power supply to 5V through LM2576 as the voltage used by the control chip and other modules.

Solution to adjust the opening width: In view of the different sizes of various sliding windows, if the smart window switch device is to be used universally, it should have the function of adjusting the opening width. This device uses a stepper motor 11 with a screw rod 17 as the actuator, which can easily calculate the relationship between the moving distance and the number of pulses. The width to be opened is set through the key module 6, and the system will automatically calculate and send it to the stepper motor 11. Due to the precise coupling between the screw rod 17 and the slider 15, the accurate opening distance can be guaranteed. This can save the limit switch and reduce the complexity of the system.

The solution that does not affect the manual opening and closing of the window: In order not to affect the function of manually opening/closing the window, an electromagnetic lock 8 is added to this device. When opening/closing the window, the electromagnetic lock 8 is energized, and the electromagnetic lock 8 stretches out to touch the baffle plate 16 of the window sash 13, driving the window sash 13 to move; after the execution, the electromagnetic lock 8 is retracted, and the window sash 13 is completely separated from the intelligent window switch device , so the manual opening and closing of the window is the same as before the installation of the window drive.

This device adopts A4988 as the motor drive module 10 of the stepper motor 11 . The A4988 is a DMOS microstepping driver with converter and overcurrent protection, which can operate bipolar stepping motors in full, half, 1/4, 1/8 and 1/16 stepping modes, output drive performance Up to 35V and ±2A. The A4988 contains a fixed off-time current regulator that can operate in slow or mixed decay modes. The converter is the key to the ease of implementation of the A4988. As long as a pulse is input into the "step" input, the motor can be driven to produce microsteps. There is no need for phase sequence tables, high frequency control lines or complex interface programming. And the direction of motor rotation can be controlled by the high and low levels of the DIR pin. Since the driving motor is easy to generate noise, the 1/16 step mode is directly used, that is, MS1, MS2 and MS3 are directly connected to VCC, and other pins are connected according to their respective functions, as long as the two I/O ports of the microcontroller are used. Control the work of the motor.

This system does not need to accurately calculate the wind speed, but only needs to judge whether the wind speed reaches a certain threshold, which is used as the driving signal for closing the window, so it is implemented in a simple and cheap way. A small fan blade is used as the detection of wind speed, and a pair of infrared tubes are placed on both sides of the fan blade. In this way, under the action of the wind force, the fan blades rotate accordingly, the infrared light is blocked, and a pulse signal is generated after the comparison circuit. The pulse frequency is proportional to the wind speed, and the approximate wind speed can be calculated by calculating the pulse frequency through software.

The above embodiments of the utility model have been described in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the scope of knowledge of those skilled in the art.
