Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of environmental purifier control circuits, and in particular to an intelligent home control system. Background Art
[0002] An air purifier primarily consists of a motor, fan, and air filter. Some models are equipped with a humidifying water tank or auxiliary purification devices such as a negative ion generator and high-voltage circuit. The air filter is the core component.

[0003] Existing purifiers typically operate in a fixed mode: once powered on, the air conditioner controls the air filter components to begin operating. These systems don't intelligently adjust the air filter based on environmental parameters, resulting in high energy consumption.

[0050] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0051] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0052] See Figure 1 The embodiment of the present invention provides a smart home control system, comprising: a controller, a sensor module, an air purification module, and a communication module. The sensor module is connected to the controller to collect and / or process environmental data. The sensor module may include multiple types. For example, it may include one or more of a PM2.5 detection circuit, a carbon dioxide (CO2) sensor, a humidity sensor, a temperature sensor, or a formaldehyde sensor. The PM2.5 detection circuit can detect PM2.5 particles; the carbon dioxide (CO2) sensor is used to detect the carbon dioxide concentration in the environment; the humidity sensor is used to detect the humidity in the environment; the temperature sensor is used to detect the ambient temperature; and the formaldehyde sensor is used to detect the formaldehyde concentration in the environment. Each sensor can detect the corresponding environmental parameter and transmit the detection data to the controller. In this way, the controller can obtain specific environmental parameter information.
[0053] The air purification module is connected to the controller, which is used to control the air purification module based on environmental data to purify the air. After the controller obtains specific environmental parameter information through the sensor module, it can control the operation of the air purification module. The air purification module is equipped with an air purifier to filter the air and thus achieve air purification. When the ambient air quality is relatively good, the controller can control the air purification module to stop operating, thereby saving air purification consumables and energy.
[0054] The communication module is connected to the controller, and the communication module is also used to communicate with the client to send environmental data to the client or receive control signals from the client under the control of the controller. The controller also controls the sensor module and / or the air purification module according to the control signal. On the one hand, the client can receive the environmental parameter information collected and transmitted by the controller, so that the client can display the environmental parameter information so that the user can obtain environmental information through the client. In addition, the user can also decide whether to start the environmental purification operation based on the current environmental parameter information. The control signal of the client can be transmitted to the controller through the communication module, and the air purification module can be turned on or off by the controller. In this way, the working mode and wind speed of the air purifier can be dynamically adjusted according to the real-time monitoring data to achieve the best purification effect, save electricity and extend the service life of the machine; in addition, remote monitoring and control of the air purification system can be achieved through mobile applications or web pages, and users can view air quality data and make adjustments anytime, anywhere. The air purification system is interconnected with other smart home devices (such as air conditioners, humidifiers, smart curtains, etc.) to provide a full range of smart home experience. By integrating voice assistants (such as Alexa, Google Assistant, etc.), users can directly control the air purifier through voice commands, greatly improving the convenience of use.
[0055] See Figure 1 、 Figure 2 and Figure 3The sensor module includes a PM2.5 detection circuit, which includes: a PM2.5 sensor, a first MOS transistor (Q101), and a second MOS transistor (Q100). The PM2.5 sensor is used to detect PM2.5 particles in the environment; the source of the first MOS transistor (Q101) is connected to the signal sending end of the PM2.5 sensor through a first resistor (R101), the source of the first MOS transistor (Q101) is also connected to the first power supply output end through a second resistor (R104), the gate of the first MOS transistor (Q101) is connected to the first power supply output end through a third resistor (R106), and the drain of the first MOS transistor (Q101) is connected to the first power supply output end of the controller through a fourth resistor (R124). The controller is connected to a signal terminal of the controller, the drain of the first MOS transistor (Q101) is also connected to the second power supply output terminal through a fifth resistor (R108); the source of the second MOS transistor (Q100) is connected to the signal receiving terminal of the PM2.5 sensor through a sixth resistor (R102), the source of the second MOS transistor (Q100) is also connected to the first power supply output terminal through a seventh resistor (R103), the gate of the second MOS transistor (Q100) is connected to the first power supply output terminal through an eighth resistor (R105), the drain of the second MOS transistor (Q100) is connected to the second signal terminal of the controller through a ninth resistor (R109), and the drain of the second MOS transistor (Q100) is also connected to the second power supply output terminal through a tenth resistor (R107).
[0056] Specifically, if Figure 3 As shown in , the PM2.5 sensor can be connected through the CN4 interface and transmit and receive signals through the PM_TX and PM_RX signal terminals. When PM_TX is a low-level signal, the source of the first MOS transistor (Q101) can be pulled down to a low-level signal, thereby turning on the first MOS transistor (Q101) and outputting a low-level signal to the controller through the -PM-TX signal terminal. When PM_TX is a high-level signal, the source of the first MOS transistor (Q101) can be pulled up to a high-level signal, thereby turning off the first MOS transistor (Q101). The -PM-TX signal terminal is pulled up to a high-level signal through the fifth resistor (R108) and the second power supply, thereby outputting a high-level signal to the controller. In this way, the controller receives the output data of the PM2.5 sensor. The voltage of the first power supply can be lower than the voltage of the second power supply. In this way, the problem of the difference between the output signal of the PM2.5 sensor and the signal of the controller can be solved.
[0057] Similarly, the operating principle of the second MOS transistor (Q100) is substantially the same as that of the first MOS transistor (Q101). The controller can send high and low level signals via the -PM-RX signal terminal to control the conduction or cutoff of the first MOS transistor (Q101), thereby outputting corresponding high and low level signals to the PM2.5 sensor, thereby achieving communication between the PM2.5 sensor and the controller. In this way, the PM2.5 sensor can transmit the collected PM2.5 particle information to the controller.
[0058] See Figure 1 、 Figure 2 and Figure 4 The air purification module includes: a motor circuit, which is connected to the fan and the controller respectively, so as to control the rotation of the fan under the action of the controller. Figure 4 As shown in , the motor circuit may include a fan interface that can be connected to a fan. This allows the fan to rotate under the control of the controller, drawing ambient air into the purifier for filtration. Fuse F1 provides short-circuit protection for the fan, while transient diodes TVS1 and TVS2 absorb transient signals from the fan to prevent damage to the controller. The controller can adjust the fan speed via the -M-PWM signal terminal and start or stop the fan via the -M-EN signal terminal.
[0059] See Figure 1 、 Figure 2 and Figure 5The communication module includes: a WIFI module, a third MOS transistor (Q10) and a fourth MOS transistor (Q12); the WIFI module is used for wireless communication connection with the client; the source of the third MOS transistor (Q10) is connected to the signal receiving end of the WIFI module through an eleventh resistor (R141); the source of the third MOS transistor (Q10) is also connected to the first power supply output end through a twelfth resistor (R136); the gate of the third MOS transistor (Q10) is connected to the first power supply output end through a thirteenth resistor (R132); the drain of the third MOS transistor (Q10) is connected to the third signal end of the controller through a fourteenth resistor (R137); the third MOS transistor (Q10) is connected to the third signal end of the controller through a fourteenth resistor (R137); The drain of the fourth MOS transistor (Q12) is also connected to the second power supply output terminal through a fifteenth resistor (R135); the source of the fourth MOS transistor (Q12) is connected to the signal sending terminal of the WIFI module through a sixteenth resistor (R142); the source of the fourth MOS transistor (Q12) is also connected to the first power supply output terminal through a seventeenth resistor (R145); the gate of the fourth MOS transistor (Q12) is connected to the first power supply output terminal through an eighteenth resistor (R148); the drain of the fourth MOS transistor (Q12) is connected to the fourth signal terminal of the controller through a nineteenth resistor (R143); and the drain of the fourth MOS transistor (Q12) is also connected to the second power supply output terminal through a twentieth resistor (R146).
[0060] Specifically, if Figure 5 As shown in , the WIFI module can be accessed through the J_WIFI interface. Signals are sent and received through the WF_TX and WF_RX signal terminals. When WF_TX is a low-level signal, the source of the third MOS tube (Q10) can be pulled down to a low-level signal, thereby turning on the third MOS tube (Q10) and outputting a low-level signal to the controller through the -WF-TX signal terminal. When WF_TX is a high-level signal, the source of the third MOS tube (Q10) can be pulled up to a high-level signal, thereby turning off the third MOS tube (Q10), and the -WF-TX signal terminal is pulled up to a high-level signal through the fifteenth resistor (R135) and the second power supply, thereby outputting a high-level signal to the controller. In this way, the controller receives the output data of the WIFI module. The voltage of the first power supply can be less than the voltage of the second power supply. In this way, the problem of the difference between the output signal of the WIFI module and the signal of the controller can be solved.
[0061] Similarly, the operating principle of the fourth MOS transistor (Q12) is substantially the same as that of the third MOS transistor (Q10). The controller can send high and low level signals via the -PM-RX signal terminal to control the conduction or cutoff of the third MOS transistor (Q10), thereby outputting corresponding high and low level signals to the WIFI module, thereby enabling communication between the WIFI module and the controller. The WIFI module can be wirelessly connected to a WIFI router. In this way, it can be connected to a remote server through the WIFI router. Since the client is also connected to the remote server, communication between the controller and the client can be achieved.
[0062] See Figure 5 The communication module further comprises: a first transistor (Q8) and a second transistor (Q9), wherein the emitter of the first transistor (Q8) is connected to a power supply, the emitter of the first transistor (Q8) is further connected to the base of the first transistor (Q8) via a twenty-first resistor (R110), and the collector of the first transistor (Q8) is connected to the power supply end of the WIFI module; the collector of the second transistor (Q9) is connected to the base of the first transistor (Q8), the emitter of the second transistor (Q9) is connected to a reference ground, the base of the second transistor (Q9) is connected to the reference ground via a twenty-second resistor (R123), and the base of the second transistor (Q9) is further connected to a control end of the controller via a twenty-third resistor (R122).
[0063] Specifically, if Figure 5 As shown in , the first transistor (Q8) and the second transistor (Q9) can be used to switch the power output of the WIFI circuit, thereby disconnecting the power supply of the WIFI circuit when the WIFI is not in use, thereby achieving the purpose of saving power. Its specific working process is that the controller can output high and low level signals through the -WF-EN signal terminal. When the -WF-EN signal terminal outputs a high level signal, the second transistor (Q9) and the first transistor (Q8) can be turned on, thereby outputting the power supply WF-V and powering the WIFI circuit. When the WIFI circuit is not needed for wireless communication, the controller can output a low level signal through the WF-EN signal terminal, thereby turning off the second transistor (Q9) and the first transistor (Q8), thereby disconnecting the power supply of the WIFI circuit, thereby achieving the purpose of saving power.
[0064] See Figure 1 、 Figure 2 and Figure 6, the smart home control system further includes: a touch circuit, the touch circuit includes a plurality of touch buttons, each of the touch buttons is connected to the controller via a current limiting resistor to send a control signal to the controller. Figure 6 As shown in , the touch circuit may include multiple touch buttons (TK1 to TK9). Each touch button can obtain touch information of a touch point and send the touch information to the controller. In this way, the controller can control the working state of each circuit module according to the touch information.
[0065] See Figure 1 、 Figure 2 and Figure 7 The smart home control system further includes a speaker circuit, which includes: a speaker, a third transistor (Q108), a fourth transistor (Q106) and a fifth transistor (Q107), wherein the base of the third transistor (Q108) is connected to the drive signal control terminal of the controller through a twenty-fourth resistor (R140), the base of the third transistor (Q108) is further connected to the reference ground through a twenty-fifth resistor (R139), the emitter of the third transistor (Q108) is connected to the reference ground, and the collector of the third transistor (Q108) is connected to one end of the speaker; the collector of the fourth transistor (Q106) is connected to the speaker through a twenty-sixth resistor (R130). The other end of the device is connected, the emitter of the fourth transistor (Q106) is connected to the output end of the speaker power supply, and the emitter of the fourth transistor (Q106) is also connected to the base of the fourth transistor (Q106) through a twenty-seventh resistor (R128); the collector of the fifth transistor (Q107) is connected to the base of the fourth transistor (Q106) through a twenty-eighth resistor (R129), the emitter of the fifth transistor (Q107) is connected to the reference ground, the base of the fifth transistor (Q107) is connected to the reference ground through a twenty-ninth resistor (R126), and the base of the fifth transistor (Q107) is also connected to the control end of the controller through a thirtieth resistor (R125).
[0066] Specifically, the controller can control the power supply of the speaker through the BUZZ_PWR signal terminal and control the sound of the speaker through the BUZZ_PWM signal terminal. The specific working process is as follows: when the controller needs to control the speaker to emit sound, it can output a high-level signal through the BUZZ_PWR signal terminal. This high-level signal can turn on the fifth transistor (Q107) and the fourth transistor (Q106), thereby outputting the power supply S12V to the speaker. At the same time, the controller also outputs a pulse signal through the BUZZ_PWM signal terminal. This pulse signal can turn on or off the third transistor (Q108), thereby controlling the output sound of the speaker.
