Description

Technical Field

[0001] This utility model relates to smart home technology. Background Technology

[0002] Currently, home renovation has entered the era of smart technology, with an increasing number of interior design styles incorporating complete smart home systems. Most existing smart home systems connect various smart devices via universal voice assistants (such as smart speakers). Each smart device exists independently, and the universal voice assistant sends commands to the relevant smart devices via the internet to complete smart tasks. This approach has the following main shortcomings: 1. General-purpose voice assistants need to be directly connected to the Internet, and the related control data is not under the user's control, which poses a network security risk; 2. General-purpose voice assistants have limited functionality and can only serve as intermediaries for transmitting commands. Each sensor in a smart home system needs to be equipped with an independent controller with wireless communication capabilities to communicate with the general-purpose voice assistant, which increases costs and the complexity of building a smart home system. 3. The device status of the general voice assistant is mainly viewed through the mobile phone. The screen is too small, making it difficult to conveniently and comprehensively obtain the control status of all smart devices in the house, resulting in a poor user experience.

Voice data and other privacy-related data from the smart devices can be anonymized and then connected to the internet via a firewall, utilizing the server's higher-performance data processing capabilities. The second LAN interface, LAN1, connects to the external network, directly linking to the internet, allowing system applications to access entertainment functions online.

[0019] Several sensor interfaces 5 support the connection of sensor devices, such as temperature and humidity sensors, optical sensors, PM2.5 sensors, and human body sensors, enabling the system to capture relevant parameters of the current environment.

The power supply voltage of each sensor interface 5 is used to power the sensor connected to that sensor interface 5, eliminating the need for the sensor to have an additional power supply cable, making the sensor connection easier. In existing smart home systems, due to the low power of the sensors, an additional power cable is usually required to power the sensor devices. In some specific implementations, the DC input voltage to the host of the smart home control system is 24V, the power management chip 2 is powered by 5V, and the power supply voltage to several sensor interfaces 5 is 5V and / or 3.3V.
