Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1:

[0025] Please see attached Figure 1 The embodiment of the present invention provides a smart home control system based on the Internet of Things, which is suitable for a smart home living room, where smart TVs, smart speakers, smart lighting systems and smart curtains from different manufacturers are installed. The control system includes an Internet of Things communication module, which is used to realize communication between smart home devices and a control center; a compatibility detection module, which is used to detect the communication protocols and control methods of smart home products from different manufacturers; an adaptive adjustment module, which is used to perform compatibility adaptive adjustment on smart home products from different manufacturers according to the compatibility detection results; and a control center, which is used to centrally control and manage the entire smart home system.

[0026] The compatibility detection module includes a protocol analysis unit and a control mode identification unit. The protocol analysis unit is used to analyze the communication protocols of smart home products from different manufacturers, and the control mode identification unit is used to identify the control modes of smart home products from different manufacturers. The protocol analysis unit analyzes the smart TV and finds that it uses the communication protocol P1a of manufacturer A. In the data format D1a, the video signal transmission method has a specific encoding format, and the audio output mode also has a unique parameter setting. The control mode identification unit recognizes that the smart TV can be controlled by a remote control and a mobile phone APP; for the smart speaker, the protocol analysis unit determines that it is the communication protocol P1b of manufacturer B. In the data format D1b, the file format support and sound effect adjustment parameters of music playback have specific specifications. The control mode identification unit determines that the smart speaker can be controlled by voice commands and mobile phone APP; the smart lighting system comes from manufacturer C, the communication protocol is P1c, and the data format is D1 In c, the light color is represented by a specific color space value, and the brightness adjustment range also has a unique setting. The control mode identification unit determines that it can be controlled by a wall switch and a mobile phone APP. The communication protocol of the smart curtain is P1 of manufacturer D. In the data format D1d, the degree of opening and closing of the curtain is represented by different numerical codes. The control mode identification unit finds that it can be controlled by a remote control and a mobile phone APP.

[0027] The adaptive adjustment module includes a protocol conversion unit and a control parameter adjustment unit. The protocol conversion unit is used to convert the communication protocols of smart home products from different manufacturers into a unified communication protocol. The control parameter adjustment unit is used to adjust the control parameters according to the control methods of smart home products from different manufacturers.

[0028] The conversion method of the protocol conversion unit comprises the following steps:

[0029] S1. Assume that the source communication protocol is P1, the target communication protocol is P2, the data format of the source communication protocol is D1, and the data format of the target communication protocol is D2;

[0030] S2. For each data item d1∈D1 in the source communication protocol, convert it into the corresponding data item d2=f(d1)∈D2 in the target communication protocol through the mapping function f;

[0031] S3. Repeat the above steps until all data items in the source communication protocol are converted into corresponding data items in the target communication protocol.

[0032] The protocol conversion unit first sets the source communication protocol to P1a, P1b, P1c, and P1d, and the target communication protocol to P2. For smart TVs, when the video signal encoding data items in the source communication protocol need to be converted, the mapping function f performs format conversion and encoding adjustment according to the requirements of the target communication protocol. The specific video encoding format in the source communication protocol is converted into a universal video encoding format in the target communication protocol through the mapping function f; for smart speakers, the data items supported by the music file format may be a series of specific file extensions in the source communication protocol, which are converted into the corresponding universal music format identifiers in the target communication protocol through the mapping function f; the color data items of the smart lighting system are color space values ​​in the source communication protocol, and the mapping function f converts them into easy-to-understand color names or codes in the target communication protocol; the numerical code of the opening and closing degree data item of the smart curtain in the source communication protocol is converted into a unified representation in the target communication protocol through the mapping function f.

[0033] The adjustment method of the control parameter adjustment unit is as follows:

[0034] Assume that the control parameters of smart home products from different manufacturers are C 1 , C 2 ,…,C n , the unified control parameter is C, and the unified control parameter C is calculated by weighted average method = (w 1 ×C 1 +w 2 ×C 2 +…+w n ×C n ) / (w 1 +w 2 +…+w n ), where w 1 、w 2 ,…,w n is the weight coefficient, which is determined according to the importance and usage frequency of smart home products from different manufacturers. Suppose the control parameter of smart TV is C 1 , such as screen brightness, contrast, volume, etc.; the control parameters of smart speakers are C 2 , such as volume, sound effect mode, etc.; the control parameters of the intelligent lighting system are C 3 , such as color, brightness, color temperature, etc.; the control parameters of smart curtains are C 4 , such as opening and closing speed, stay position, etc.; determine the weight coefficient according to the importance and frequency of use of these devices. If the family often watches TV, the importance of smart TV is relatively high, and a higher weight coefficient w is given. 1 , if the user likes to listen to music, the frequency of using the smart speaker is high, and a correspondingly higher weight coefficient w is given 2 , the unified control parameter C is calculated by weighted average method = (w1 ×C 1 +w 2 ×C 2 +w 3 ×C 3 +w 4 ×C 4 ) / (w 1 +w 2 +w 3 +w 4 ).

[0035] The control center includes a device management unit, a scene setting unit and a remote control unit. The device management unit is used to manage the information of smart home devices, the scene setting unit is used to set different scene modes, and the remote control unit is used to remotely control smart home devices. The device management unit includes device addition, device deletion, device information query and device status monitoring functions. The scene setting unit sets different scene modes according to user needs, including but not limited to home mode, away mode, sleep mode, movie mode, music mode and waking mode. Each scene mode corresponds to a set of control parameters of smart home devices. The remote control unit remotely controls smart home devices through mobile phone APP and web pages, and users can control and manage the smart home system anytime and anywhere. The Internet of Things communication module adopts wireless communication technology, including ZigBee, Wi-Fi and Bluetooth.

[0036] Specifically, users can query the brand, model, resolution and other information of smart TVs through the device management unit to understand their current playback status, signal source, etc. For smart speakers, users can query their brand, model, supported audio formats, etc., as well as the currently playing music tracks and volume. For smart lighting systems, users can query the color mode, brightness range, whether timer switches are supported, and other information. For smart curtains, users can query their brand, model, curtain material and current opening and closing status. The device status monitoring function displays the operating status of these devices in real time, such as whether the smart TV is turned on, the type of program currently being played, whether the smart speaker is playing music, whether the sound effect mode is surround sound, the current color and brightness of the smart lighting system, and whether the opening and closing degree of the smart curtains meets the settings. When setting the viewing mode, the smart lighting system automatically dims to an appropriate brightness, the smart curtains automatically close, the volume of the smart speaker is adjusted to a moderate level, and the smart TV switches to a specific video input source and adjusts the picture parameters. When setting the music mode, the smart lighting system switches to soft colors, the smart curtains remain slightly open to create an atmosphere, and the smart speaker is adjusted to the best sound effect mode. When users are out, they can remotely control the smart home devices in the living room through the mobile phone APP. They can turn on the smart TV and smart speakers in advance to prepare the entertainment environment when they return home, or remotely adjust the color and brightness of the smart lighting system, and control the opening and closing degree of the smart curtains.

[0037] Embodiment 2:

[0038] Please refer to the attached Figure 1 , an embodiment of the present invention provides a smart home control system based on the Internet of Things, which is suitable for a smart home bedroom and is equipped with smart air conditioners, smart air purifiers, smart humidifiers and smart bedside lamps from different manufacturers.

[0039] The protocol analysis unit analyzes that the smart air conditioner uses the communication protocol P1e of manufacturer E. In the data format D1e, the temperature setting range and wind speed adjustment mode have specific specifications. The control mode identification unit identifies that the smart air conditioner can be controlled by the remote control and mobile phone APP; the smart air purifier uses the communication protocol P1f of manufacturer F. In the data format D1f, the air quality detection indicators and purification mode parameters are uniquely represented. The control mode identification unit determines that it can be controlled by the touch panel and mobile phone APP; the smart humidifier uses the communication protocol P1g of manufacturer G. In the data format D1g, the humidity setting value and spray intensity are represented by specific numerical values. The control mode identification unit determines that it can be controlled by the mobile phone APP and buttons; the communication protocol of the smart bedside lamp is P1h of manufacturer H. In the data format D1h, the light color and brightness adjustment method have specific modes. The control mode identification unit finds that it can be controlled by touch and mobile phone APP.

[0040] The protocol conversion unit converts these different communication protocols into a unified target communication protocol P2. For the temperature data item of the smart air conditioner, the temperature setting value in the source communication protocol is converted to the corresponding value in the target communication protocol through the mapping function f. The temperature in the source communication protocol is expressed in degrees Celsius, and it may be expressed in degrees Fahrenheit in the target communication protocol. The mapping function f performs the corresponding conversion. The air quality detection index of the smart air purifier may be a series of numerical codes in the source communication protocol, which are converted into an easy-to-understand air quality level description in the target communication protocol through the mapping function f; the representation of the humidity setting value and spray intensity data items of the smart humidifier in the source communication protocol is converted into a unified format in the target communication protocol through the mapping function f; the mode of the light color and brightness adjustment data items of the smart bedside lamp in the source communication protocol is converted into the corresponding settings in the target communication protocol through the mapping function f.

[0041] The control parameter of the smart air conditioner is C 5 , such as temperature setting value, wind speed, operation mode, etc.; the control parameters of the smart air purifier are C 6 , such as air quality detection frequency, purification mode, fan speed, etc.; the control parameters of the smart humidifier are C 7 , such as humidity setting value, spray intensity, water tank capacity, etc.; the control parameters of the smart bedside lamp are C 8 , such as light color, brightness, timer switch, etc. The weight coefficient is determined according to the importance and frequency of use of these devices. If the user has high requirements for bedroom temperature, the importance of smart air conditioner is relatively high, and a higher weight coefficient w is given. 5 If the user frequently uses the humidifier in the dry season, the frequency of use of the smart humidifier is higher, and a correspondingly higher weight coefficient w is given 7 , the unified control parameter C is calculated by weighted average method = (w 5 ×C 5 +w 6 ×C 6 +w 7 ×C 7 +w 8 ×C 8 ) / (w 5 +w 6 +w 7 +w 8 ).

[0042] Users can query the brand, model, energy consumption and other information of the smart air conditioner through the device management unit, as well as the current temperature setting and operating status. For smart air purifiers, you can query their brand, model, filter replacement cycle, etc., as well as the current air quality test results and purification mode. For smart humidifiers, users can query their brand, model, water tank capacity and remaining water volume. For smart bedside lamps, users can query their brand, model, light color mode and brightness adjustment range. The device status monitoring function displays the operating status of these devices in real time, such as whether the smart air conditioner is turned on and the current temperature; whether the smart air purifier is running and the current air quality level; whether the smart humidifier is working and the current humidity; whether the smart bedside lamp is turned on and the current light color and brightness.

[0043] When the scene setting unit sets the sleep mode, the smart air conditioner automatically adjusts the temperature to a range suitable for sleeping, the smart air purifier switches to silent mode and reduces the operating power, the smart humidifier automatically adjusts the humidity to a comfortable level, and the smart bedside lamp dims the light brightness and switches to soft colors. When setting the wake-up mode, the smart air conditioner preheats the room in advance, the smart air purifier improves the purification efficiency, the smart humidifier automatically adjusts the spray intensity according to the indoor humidity, and the smart bedside lamp gradually brightens the light and switches to bright colors.
