[0040] See also Figure 1 and Figure 2 The embodiment of the present application proposes a smart home central control device 10, including a body, and an information collection module 2, an information processing module 3, a remote communication module 4, an identification function module 5 and a floating display module 6 arranged on the body.

[0041] The information acquisition module 2 is used to collect the indoor environmental status and transmit the collected data to the information processing module 3, which further analyzes and processes the data. The information acquisition module 2 may include a temperature sensor for collecting temperature information, a humidity sensor for collecting indoor humidity information, a gas sensor for detecting and measuring indoor air quality, a light sensor for collecting light brightness, a pyroelectric infrared sensor for sensing infrared radiation from surrounding objects and organisms, a smoke sensor for collecting smoke status, and a PM2.5 sensor for detecting and measuring the concentration of PM2.5 particles in the air. For some structural forms, please refer to Figure 3 The information acquisition module 2 includes multiple sensors and a data acquisition card. The multiple sensors are used to collect indoor environment data and send the collected data to the data acquisition card. The data acquisition card converts the data into analog digital data and sends it to the information processing module 3.

[0042] For example, the gas sensor can be used to detect the concentration of harmful gases (such as formaldehyde, carbon dioxide, carbon monoxide, etc.) in the room, and transmit the gas data to the information processing module 3, which analyzes the data to monitor whether the indoor environment is in a state of fire, gas leakage, etc., to provide an alarm or control the operation or shutdown of the execution device. The user can combine and set the sensor types according to the needs, or can select one to set, and there is no specific restriction on the type and quantity of the sensor.

[0043] See also Figure 4, the remote communication module 4 is connected to the information processing module 3 for communication, and is used to interact with external devices. Among them, the remote communication module 4 may include a Bluetooth module, a WIFI module, a Zigbee module, etc. The external device may be an execution device or a user terminal. In some communication modes, the information processing module 3 may be connected to the execution device through a Bluetooth module, a WIFI module, a Zigbee module, etc. The execution device may be an execution device such as a humidifier, an air conditioner, a television, a washing machine, an electric rice cooker, an alarm, a water heater, etc. The information processing module 3 may be connected to the user terminal through a WIFI module or a Zigbee module, etc. The user terminal may be a mobile phone, a computer, a tablet, a controller, etc. The user may connect different execution device user terminals according to actual needs, and no specific restrictions are made here. In this way, the user can input a control instruction to the information processing module 3 remotely, so as to control the execution device to run or shut down, and also obtain the running status of the execution device. For example, the operating mode and temperature of the bedroom air conditioner are set on the mobile phone, the remaining working time of the washing machine is obtained, the working time of the humidifier is set, etc. In addition, based on the data collected by the sensors in the information acquisition module 2, the information processing module 3 analyzes and notifies the user of the situation in a timely manner through the WIFI module when it believes that the indoor environment is at risk. It can also issue work instructions to the alarm, so that the user can understand the situation in a timely manner through the alarm.

[0044] See also Figure 5 The recognition function module 5 is used to sense the indoor environment, identify the position of the user and indoor objects, and perform three-dimensional modeling. The output end of the recognition function module 5 is electrically connected to the input end of the information processing module 3. Among them, the recognition function module 5 may include any one or any combination of a motion capture module, a face recognition module, and an object recognition module. The recognition function module 5 may include a visible light camera, an infrared camera, and a laser radar. Furthermore, the visible light camera is a fisheye lens structure with a field of view greater than 100°. When the indoor lighting is good, the indoor environment is photographed. The infrared camera also uses a wide-angle lens to photograph the indoor environment when the indoor lighting is insufficient at night. The laser radar is used to identify the position of indoor objects. The data collected by the recognition function module 5 is sent to the information processing module 3 for processing and storage.

[0045] It should be noted that the visible light camera can be composed of a lens, an image sensor, a processor and a memory. The lens is used to focus light, the sensor is responsible for converting light signals into electrical signals, the processor performs digital signal processing operations, and the memory is used to store image and video data. The visible light camera can shoot dynamic videos or static photos, and the processor transmits the digital signals of dynamic videos or static photos to the information processing module 3. When the information processing module 3 analyzes data, first, the information processing module 3 is provided with relevant data sets and relevant processing algorithms, such as: face recognition algorithm, motion capture algorithm, object recognition algorithm, etc.

[0046] For example, when performing face recognition, it is first necessary to detect faces in images or videos to determine the position and size of faces. Common face recognition algorithms include Haar cascade classifiers and convolutional neural networks based on deep learning. After detecting a face, it is necessary to extract recognizable features from the face image. Traditional methods include Local Binary Patterns (LBP), Principal Component Analysis (PCA), and Linear Discriminant Analysis (LDA). Now, methods based on deep learning, such as Convolutional Neural Networks (CNN) and facial key point detection, are also widely used. The extracted facial features are compared and matched with existing facial features. Here, the distance or similarity between features is usually calculated to measure the similarity between two faces. Common matching methods include Euclidean distance, cosine similarity, and Support Vector Machine (SVM). Judgment and decision are made based on the results of feature matching. If the matching result exceeds the set threshold, it is determined to be the same face, otherwise it is considered to be different faces. In this way, the user can first enter the face of himself or his family, so that the application can identify whether the human body in the video or image is the user or family member. If it is not the recorded facial feature, the information processing module 3 can transmit a signal to the alarm or the user's mobile phone, thereby realizing the function of security monitoring.

[0047] When performing motion capture, motion capture technology is used to capture and analyze the target person's movements in real time. Motion capture technology can use various sensors (such as inertial measurement units, electromagnetic sensors, cameras, etc.) to obtain the target person's movement and posture information, and convert it into digital signals and pass the digital signals to the information processing module 3 for analysis and processing. The motion capture module set in this application can play many interesting roles in the home, for example: somatosensory games, by using cameras or other sensors to detect the player's movements and convert them into character movements in the game. Such somatosensory games can allow players to participate in the game more deeply, improving the fun and entertainment of the game. Fitness assistance: By using cameras or other sensors, the user's movements can be tracked in real time, and then feedback and guidance can be given to guide the user to perform correct exercise postures and help users perform effective fitness training. Home health care, for example, in homes where the elderly live, by using cameras or other sensors, this application can monitor the elderly's daily activities, postures, etc. in real time, and then provide health advice and guidance to help the elderly stay healthier.

[0048] Of course, the motion capture module can also be combined with other technologies to achieve other functions. For example, after obtaining the motion and posture information of the target person, the motion capture module can be combined with tracking technology to track it in real time. The tracking algorithm can be implemented based on the appearance, motion and other characteristics of the target, such as based on Kalman filter, particle filter, correlation filter, etc. Then, combined with face recognition technology, the target task is identified and judged. If it is not the user, the information processing module 3 can transmit a signal to the alarm or the user's mobile phone, which can play a role in monitoring and security for the family.

[0049] When performing object recognition, first collect image or video datasets containing the desired objects, and use computer vision technology to extract useful features from the images or videos. Common feature extraction methods include Local Binary Patterns (LBP), Histogram of Oriented Gradients (HOG), etc. Object recognition algorithms, such as Convolutional Neural Network (CNN) or target detection algorithms (such as Faster R-CNN, YOLO, etc.), are applied to detect images or videos. These algorithms can mark the area of ​​interest in the image and give the location and bounding box of the object. The extracted object area is identified using a classification algorithm or a deep learning network. Traditional machine learning algorithms (such as support vector machines, random forests, etc.) or deep learning models (such as convolutional neural networks) can be used to classify object areas into predefined object categories. In addition, there are some open source computer vision libraries and frameworks available, such as OpenCV, TensorFlow, PyTorch, etc., which provide a wealth of tools and functions to help achieve object recognition tasks.

[0050] See also Figure 6 The floating display module 6 is connected to the information processing module 3 for communication and is used to display text information and / or graphic images in the air. The floating display content is determined by the display content sent by the data processing module to the display screen. If the data format sent by the data processing module to the display screen is a digital human image, the user can see the floating digital human image in 2D format from the floating display module 6 in the smart home central control device 10; if the data format sent by the data processing module to the display screen is prompt text information, the user can see the floating prompt information from the floating display module 6 in the smart home central control device 10.

[0051] In some structural forms, see Figure 6 The suspended display module 6 includes a box assembly 61, in which a display device 62, a beam splitter 63, and a retroreflective array film 64 are arranged. The display device 62 has a light-emitting surface and is in communication connection with the information processing module 3. The information processing module 3 is used to control the image source displayed by the display device 62. The beam splitter 63 is arranged opposite to the light-emitting surface, so that the light emitted by the light-emitting surface can be transmitted to the retroreflective array film 64 after passing through the beam splitter 63. The retroreflective array film 64 has a retroreflective surface, and the retroreflective surface is arranged opposite to the beam splitter 63. The retroreflective surface receives the transmission light from the beam splitter 63 and reflects the transmission light to the beam splitter 63, so that the transmission light passes through the beam splitter 63 and converges in the air outside the box assembly 61 to form a suspended image 65 corresponding to the image source.

[0052] In order to facilitate the installation of the display device 62, the beam splitter 63, and the retroreflective array film 64 in the box assembly 61, multiple tooling can be set in the box assembly 61, and the display device 62, the beam splitter 63, and the retroreflective array film 64 are respectively fixed on the tooling, so that they can be installed and fixed and light transmission can be achieved. Of course, installation holes with different angles can also be opened in the box assembly 61, and the display device 62, the beam splitter 63, and the retroreflective array film 64 are respectively fixed in the installation holes, and this application does not limit this.

[0053] In order to improve the viewing experience of the user when watching the suspended image 65, in some structural forms, the suspended image 65 is parallel to the vertical direction. With this arrangement, the suspended image 65 has a better visual effect and improves the user experience. In order to achieve the parallelism of the suspended image 65 with the vertical direction, the angle α between the side of the display device 62 facing away from the light-emitting surface and the horizontal direction is in the range of 0° to 30°; the angle β between the side of the beam splitter 63 close to the image source and the horizontal direction is in the range of 30° to 45°; the angle θ between the side of the retroreflective array film 64 close to the image source and the horizontal direction is in the range of 60° to 90°. The display content on the display device 62 passes through the beam splitter 63 and the retroreflective array film 64 successively, and a suspended image 65 is formed on the outside of the beam splitter 63. The screen distance of the suspended image 65 can be about 10 cm and is parallel to the vertical direction. The size of the suspended display content is related to the size of the beam splitter 63, the size of the display device 62 and the size of the retroreflective array film 64. Specifically, an 8.6-inch LCD screen is selected, and the size of the retroreflective array film 64 and the beam splitter 63 are both about 40 cm by 40 cm, so that the display area size of the suspended image 65 is about 15 cm by 15 cm.

[0054] The content displayed by the suspended image 65 is determined by the display content sent by the information processing module 3 to the display device 62. If the data format sent by the information processing module 3 to the display device 62 is a digital human image or an image image, the user can see the suspended digital human image or graphic image; if the data format sent by the information processing module 3 to the display device 62 is a prompt text message, the user can see the suspended text message. The present application can generate a suspended image 65 by setting a suspended display module 6. The suspended image 65 can interact with the user to increase the sense of participation and interactivity. Furthermore, the digital human image displayed by the suspended image 65 can be customized into a relative or virtual character who is not around, and communicates with the user through voice, making the digital human image more humanized, with a stronger sense of reality, and bringing more humanistic care to the user.

[0055] In order to realize the voice interaction between the smart home central control device 10 and the user, the smart home central control device 10 also includes a sound pickup module and a sound playback module. The sound pickup module and the sound playback module are both connected to the information processing module 3 by signal. The sound pickup module is used to receive the user's voice command, and the sound playback module is used to play the voice. Specifically, the sound pickup module can be a microphone or a microphone, which is used to receive the voice signal and convert the voice signal into text, and the sound playback module outputs it to the user through the voice signal. The present application uses the sound pickup module to enable the smart home central control device 10 to obtain the user's control command when it is far away, and after being processed by the information processing module 3, the corresponding content image can be suspended and displayed through the suspension display module 6, and the image can include image information and text information. In this way, the user can control the smart home central control device 10 from a distance when he is not in front of the smart home central control device 10, so that the convenience of use can be improved, and the setting of the suspension display module 6 can be used to confirm whether the execution of the command is in place at a distance, so that the interactive experience with the smart home central control device 10 is stronger. In addition, the execution of the command can be further confirmed by the sound playback module.

[0056] Furthermore, the sound pickup module and the sound playback module can be electrically connected to the information processing module 3, and the information processing module 3 is connected to the data source via WIFI. The data source can be a music data source, a weather data source, etc., so that users can get more services, for example: users can ask about the weather forecast, listen to music, news, etc.

[0057] Specifically, in the process of receiving voice signals and converting voice signals into text, the sound pickup module can use the automatic speech recognition (ASR) algorithm to match the voice signals with the language model, acoustic model, etc., and transcribe the voice into text. Then, the transcribed text is semantically parsed to identify information such as the user's intention, entity, and demand. Among them, the natural language understanding (NLU) algorithm can be used to perform lexical analysis, syntactic analysis, and intention recognition on the text to convert the user's semantics into a machine-understandable representation. Then, according to the user's intention and the state of the system, it is determined how the system generates a reply. Among them, the dialogue management (DM) algorithm can be used to intelligently generate appropriate replies by maintaining the dialogue state, learning user behavior patterns, and planning system responses. Based on the decision results of the dialogue management, the system generates a reply text. Among them, a predefined reply template, automatically generated text, or a natural language generation (NLG) algorithm can be used to generate a natural and fluent reply. Finally, the generated reply text is converted into a voice signal, and the voice signal of the playback module is output to the user.

[0058] In order to facilitate the installation and operation of each module, the body includes a first shell 11 and a second shell 12, and the information collection module 2, the information processing module 3, and the remote communication module 4 are arranged in the first shell 11, wherein a plurality of installation positions are arranged on the inner wall of the first shell 11, and a plurality of sensors are installed in the installation positions, and a through hole is arranged on the installation position that penetrates the outer wall of the first shell 11. In this way, the through hole can prevent the internal components of the smart home central control device 10 from affecting the sensor measurement results. The identification function module 5 and the floating display module 6 are arranged in the second shell 12, and the first shell 11 and the second shell 12 can be made of plastic or metal, wherein the second shell 12 is located at the top of the first shell 11. With such an arrangement, the identification function module 5 and the floating display module 6 both have a certain height, so that the identification function module 5 has a larger and wider viewing angle, and at the same time, the height of the display area of ​​the floating display module 6 is more in line with the user's observation needs.

[0059] In order to improve the diversity of the use of the smart home central control device 10, the smart home central control device 10 also includes a motion function module, which includes a walking component 71 and a driving component 72; the first shell 11 is installed on the walking component 71, and the information collection module 2, the information processing module 3, and the remote communication module 4 are arranged on the second shell 12. Among them, the walking component 71 can be a roller or a track, and the roller or track is driven by a motor to move, so that the smart home central control device 10 can walk in the front and back, left and right directions. In addition, the driving component 72 is arranged on the first shell 11 and is used to drive the second shell 12 to move in at least one direction on the Cartesian coordinate system and / or the polar coordinate axis, so that the floating display module 6 and the identification function module 5 can be controlled to move in at least one direction of up and down, left and right, front and back, or around the rotation axis of the driving component 72. The driving component 72 can be a six-axis manipulator, a robot, or a plurality of different linear drive modules, shafts and bearings. Here, the specific form of the driving component 72 is not limited. Such a configuration can make the floating display module 6 have a larger display range, making it easier for users to observe the floating image 65 at different angles. It can also increase the range of the recognition function module 5 to perceive the indoor environment, and can more efficiently recognize indoor objects, providing users with a better experience.

[0060] Furthermore, the recognition function module 5 is provided with a laser radar, which obtains distance and three-dimensional shape information by scanning the environment with a laser beam. By analyzing and identifying the point cloud data in the environment, obstacles in the path can be detected, and this information can be used to plan and control the automatic walking of the walking component 71, so that the smart home central control device 10 can realize the patrol monitoring function. Specifically, when the user is not at home, the information processing module 3 collects data from each sensor in the information acquisition module 2 in real time, analyzes the indoor environmental conditions, and if a risk occurs, turns on the recognition function module 5, and sends the indoor real-time conditions to the user in the form of a video through the remote communication module 4. The walking component 71 can drive the information acquisition module 2 and the recognition function module 5 to collect information and take photos at multiple locations indoors. Compared with the central control form fixed on the wall, the present application has a good sense of interaction, more functionality, and better monitoring effect.
