Detailed Description
The invention will now be further described with reference to the following examples and drawings:
the invention is based on the development trend of smart home, combines the existing scientific and technological means, monitors the environment outside the window in real time, and can better serve users.
The automatically controllable intelligent window based on the environmental factor change mainly comprises: the system comprises a perception environment factor change system, an environment change response system, a solar power supply system and a transmission system; the environment factor change sensing system is formed by circuits of a haze sensor, a temperature and humidity sensor, a raindrop sensor, an infrared sensor and the like, timely responds to the change of environment factors (haze, temperature, raindrops and human bodies), and transmits data information to an environment change response system with a single chip microcomputer core; the solar power supply system is a power system of the system, comprises a voltage transformation device, a voltage stabilization device, a solar cell panel voltage output device, a lithium battery and the like, and is connected together by control signals; the transmission system comprises a transmission shaft control circuit, a transmission shaft and a driving motor which are connected together by control signals.
The intelligent window capable of being automatically controlled based on the environmental factor change adopts an STM32 single chip microcomputer, and various working systems of the intelligent window are controlled through an STM32 single chip microcomputer. If outdoor haze and raised dust exist or PM2.5 exceeds the standard, the window can open the haze-proof window screen to prevent haze particles and dust from entering the room; if the outdoor rains, the window can be automatically closed; if a thief attempts to enter the room through the window, the window will automatically alarm.
The system for sensing the environmental factor change is formed by taking a sensor as a core module, wherein the sensor comprises:
the haze sensor adopts a method of combining a dust sensor based on a light scattering principle with Arduino to detect haze. The specific scheme is that an infrared light-emitting diode in the dust sensor emits infrared light, and a phototransistor on the other side receives the intensity of light refracted by dust and transmits the light to Arduino. The sampling period is designed in software, and is generally t-1 s, and the detection threshold is 75ug/m3。
The temperature and humidity sensor adopts DS18B20 and DHT11 digital temperature and humidity sensors, applies a special digital module acquisition technology and a temperature and humidity sensing technology, utilizes a resistance-type humidity sensing element and an NTC temperature measuring element of the sensor, and has a sampling period of 1s, a suitable temperature range of 18-24 ℃ and a humidity range of 45-65 percent according to the characteristics of the sensor.
The raindrop detection adopts YL-83 raindrop sensor. The sensor is divided into two parts, a sensing board and a signal comparison circuit. The sensing board is mainly used for sensing whether rainwater falls or not and is arranged outdoors, and the signal comparison circuit is used for comparing and processing signals collected by the sensing board and then outputting the signals to the single chip microcomputer for analysis and calculation. And the digital signal is selected to be output in combination with actual conditions, when no rainwater is detected, the induction plate is not conducted, the DO port outputs high level, and the singlechip judges that the rainwater does not fall. When raindrops fall, the induction plate is conducted, the DO outputs a low level, and the single chip microcomputer judges that the raindrops exist.
The infrared sensor adopts a passive pyroelectric infrared detector HC-SR 501. The normal body temperature of human body is maintained at about 36-37 deg.C, the temperature range can emit infrared ray with central wavelength of 8-12um, HC-SR501 works by detecting infrared ray with about 10um emitted by human body temperature.
The sensors are distributed outside the window frame, and can normally work by responding to the change of environmental factors (haze, temperature, raindrops and human bodies) and transmitting sensed data information to an environmental change response system with a single chip microcomputer core.
The environment change response system consists of 3 STM32 single-chip microcomputers, two of which are used as sub-control systems for processing relevant factors, and the other single-chip microcomputer is used as a total processing center. In addition, the master control singlechip has the priority to the incoming signal: people > rainfall > haze > humiture, so handle more have the rationality. The 3 singlechips are respectively divided and coordinated to work, so that the whole system works orderly.
A voltage stabilizing circuit is designed in the solar power supply system, so that the solar battery can charge the battery of the whole system. The voltage stabilizing circuit is used for a switch type power supply chip LM2577 voltage boosting module. The input voltage range of the chip is 2-24V, the output voltage can reach 28V at most, the driving capacity of 2 amperes, the output voltage of the module is adjustable, the charging voltage is higher than twenty-four percent of the voltage of the battery according to the charging standard of the solar battery, the output voltage of the voltage stabilizing module is adjusted to be about 7v, and the power is continuously supplied to the lithium battery. The circuit is embedded in the window frame, so that the circuit is integrated with a window conveniently.
The main structure of the transmission system is a five-wire four-phase stepping motor 28BYJ-48 driven by a 5V power supply. The stepping motor converts the electric pulse into corresponding angular displacement or linear displacement, and the angle of each step of the stepping motor is constant. Under the conventional condition, the stop position and the rotation speed of the window are only dependent on the frequency and the pulse number of the pulse signal, are independent of the ambient temperature, the air pressure and the vibration, are not influenced by voltage fluctuation, and can be used for controlling the opening and closing of the window. The structure is embedded in the window frame with the motor, directly utilizes the rotation of motor to drive the inside and outside switch of window.

Description figure 2 is a schematic diagram of an environmental factor sensing module detailing the function of various sensors. Namely sensing which environmental factors, power supply modes, expression forms among the environmental factors and the power supply modes and the connection with the main control single chip microcomputer.
The attached figure 3 of the specification is a layout schematic diagram of each module, which particularly illustrates the actual layout situation of each module and each sensor on the push-pull type window, and the solar cell panel is placed above one outdoor side of the window frame to better receive sunlight; the liquid crystal display panel, the main control panel, the temperature and humidity sensor and the stepping motor are sequentially arranged on the right side of the indoor side of the window frame, so that the required space is reduced, and the influence on the accuracy of related measurement results due to overlong circuits is avoided; pyroelectric sensor, raindrop sensor arrange in the outdoor one side below of window frame, make measuring condition more accord with actual conditions, and the dust sensor avoids each device to disturb at the outdoor one side left surface of window frame. Through reasonable layout arrangement, each module can fully exert the utility, the reliability of the measured parameters is ensured, and the interference of other irrelevant factors is avoided.
The idea of programming control is shown in the attached figure 4 of the specification, a specific threshold value is set in the programming according to the environmental factors, and once the environmental factors reach the threshold value set by the program, the program judges whether the motor needs to be controlled to make a corresponding instruction so as to control the opening and closing of the window and the window screening. Thus, changes in the environment can be monitored in real time.
In conclusion, the air-conditioning system is simple in principle, low in cost, capable of economically and effectively solving the problem that air damages human bodies, high in flexibility and great in market potential.
