The whole house intelligent curtain includes a number of intelligent curtains, and each intelligent curtain can be interconnected with other intelligent curtains through the Bluetooth communication module.

[0026] like Figure 2 As shown, the specific workflow of acquiring control instructions is as follows: a microphone is built into the hardware control terminal to acquire the user's voice input, and the user's voice signal acquired by the microphone is sent to the voice control module for signal preprocessing, wherein the voice control module has a built-in deep learning model and a natural language processing algorithm, and the voice data after signal preprocessing is sent to the deep learning model for data training to establish and improve the acoustic model, and on the other hand, the natural language processing algorithm is used to extract the features of the user's voice signal, and the keyword corresponding to the user's voice signal is obtained after combining it with the acoustic model, and the keyword is output as the recognized control instruction result to the Bluetooth communication module on the hardware control terminal for sending.

[0027] The voice control module performs signal preprocessing on the input user voice signal after deep noise reduction processing, wherein offline self-learning of data training is supported in the deep learning model, and the voice control module has a built-in command word upgrade module, which has a built-in command word database for voice control. After obtaining the keywords corresponding to the user voice signal, the command word upgrade module is used to replace the keywords with command words, and the replaced command words are output as the recognized control instruction results to the Bluetooth communication module on the hardware control terminal for sending.

[0028] The voice control module adopts the 3rd generation hardware BNPU technology, supports DNN\TDNN\RNN\CNN and other neural networks and parallel vector operations, and can realize functions such as voice recognition, voiceprint recognition, command word self-learning, voice detection and deep learning noise reduction. The block diagram of the voice recognition system is as follows: Figure 5 As shown in the software flow chart, Figure 6 As shown.

After the main control chip in host one receives the control instruction sent by the hardware control terminal, it is passed to the Bluetooth hardware through the hardware interface for data transmission by the radio frequency antenna. After the host two paired with the transmitted data receives the data through the radio frequency antenna, the Bluetooth hardware passes the data to the main control chip of host two through the hardware interface to control the whole-house smart curtain to take corresponding actions.

[0030] The basic principle of Bluetooth communication technology is to use radio waves in the low-power frequency band (2.402GHz to 2.480GHz) to establish short-range wireless connections between devices to achieve data transmission and communication. This technology can form a reliable communication link between multiple devices through a decentralized network structure as well as fast frequency hopping and short packet technology. Bluetooth Mesh communication technology adopts a mesh topology structure, and each device is a node in the network with the ability to send, receive and forward data. This structure enables Bluetooth devices to form a node network with each other, thereby achieving a wider range of management and control. Through multi-hop communication and broadcast mechanisms, Bluetooth Mesh realizes flexible interconnection and data transmission between devices.

[0031] The innovations of adding voice modules to Bluetooth Mesh are mainly reflected in the following aspects:

[0032] 1. Whole-house intelligent voice control: The Bluetooth Mesh network itself has a powerful networking capability that can cover the entire home area and realize the interconnection of all devices in the house. After adding the voice module, users can directly control various devices in the Mesh network, such as lights, curtains, air conditioners, etc., through voice commands, realizing intelligent voice control without blind spots in the whole house.

[0033] 2. Improve the convenience of interaction: Traditional smart home control methods often rely on mobile phone apps or remote controls, which are relatively cumbersome to operate. The voice module allows users to interact with smart home devices through natural language, greatly improving the convenience of use and user experience.

[0034] 3. Support multi-device linkage: In the Bluetooth Mesh network, devices with voice modules can be linked and controlled with other smart devices. For example, users can use voice commands to control lights, curtains and other devices in multiple rooms at the same time, realizing scene-based intelligent control.

[0035] 4. Enhanced voice recognition capabilities: With the continuous development of voice recognition technology, Bluetooth Mesh voice modules can support more accurate voice recognition and richer voice commands. This allows users to interact with smart home devices in a more natural and intuitive way, improving the intelligence of the system.

[0036] 5. Remote wireless upgrade and maintenance: The Bluetooth Mesh voice module supports remote wireless upgrades, which means that new features and bug fixes can be pushed to the device regularly to improve the stability and security of the device. At the same time, remote wireless upgrades also simplify the maintenance of the device and reduce the maintenance cost of the user. The block diagram of Bluetooth transmission and online OTA upgrade is as follows Fig. 9 shown.

[0037] like Figure 4 As shown in the figure, the specific workflow of WiFi wireless communication is as follows: the WiFi wireless communication module in the hardware control terminal is connected to the intelligent gateway device, the intelligent gateway device is connected to the cloud platform through the MQTT proxy protocol, and the cloud platform and the mobile client are connected through the mobile data network; in addition, the WiFi wireless communication module in the hardware control terminal can also be directly connected to the cloud platform through the MQTT proxy protocol, and the cloud platform and the mobile client are connected through the mobile data network. The device data transmission network block diagram is shown in the figure. Fig.10 shown.

[0038] The present invention aims to provide an intelligent curtain system based on Bluetooth communication, WiFi communication and offline voice collaborative control. The system not only has the manual opening and closing method of traditional curtains, but also can interconnect the curtains of the whole house through the Bluetooth communication module, and use the voice module integrated in the hardware control terminal to voice control the curtains of the whole house. In terms of remote control, the system connects the cloud platform and the mobile client through the WiFi wireless communication module to communicate. Users can view the status of curtains in each room in real time through the mobile client, and realize remote one-key opening and closing of curtains in the whole house or designated rooms. In addition, the curtains can also be set to switch on and off at a scheduled time in the mobile client to prevent the situation of forgetting to close the curtains before resting at night.

[0039] Among them, the voice control module adopts deep learning and natural language processing technology; it can self-learn offline and replace command words; it can deeply reduce noise and recognize more accurately. The Bluetooth communication module has low power consumption, reducing overall energy consumption; the communication is highly real-time and the hardware cost is low; it has high security and is not easy to leak privacy. The interface of the hardware control terminal is simple and easy to understand, easy to learn and operate; it has complete functions and can add new functions through software upgrades; it has good compatibility and can run on Android or IOS platforms. The WiFi wireless communication module has high transmission efficiency and fast networking speed; it has a long communication distance and is widely used; data transmission is safe and reliable, and it is not easy to lose data.

[0040] Traditional smart home or home appliance products such as curtains often only have the manual or voice control switch function of a single curtain when they leave the factory, and cannot realize the interconnection of curtains in the whole house, as well as the functions of remotely viewing and controlling the status of curtains in the whole house. The intelligent voice curtain system with Bluetooth communication module, voice control module and WiFi wireless communication module is used to interconnect curtains in the whole house. It not only has the voice operation that the elderly and children like and the remote operation function that young people like, but also realizes the one-button switch of curtains in the whole house or curtains in designated rooms. At the same time, it also supports the mobile client to time the opening and closing of curtains in the whole house to prevent the situation of forgetting to close the curtains before going to bed at night. It meets the different needs of different groups of people and breaks the difficulties of interconnection and collaborative control of traditional smart small appliances. For the use of smart furniture and home appliances, especially lighting facilities, the ability to perform voice control satisfies the convenience of use by the elderly and children at home, and at the same time has the remote operation function, which greatly facilitates the monitoring and operation of equipment outside the house by young people. At the same time, the most important point of the system is that users can customize the working mode of smart appliances according to their own needs, greatly expanding the use scenarios of kitchen appliances to better integrate into people's lives. For example, the system is used in smart small appliances, such as curtains, toilets, lights, and kitchen appliances, to enable real-time status data monitoring and operation of a series of small appliances through mobile clients, as well as customization of voice commands and working modes.
