Changhong recently held a product tasting event at the 321 Cultural Industry Park in Chengdu, where the CHiQ TV Q5K was officially unveiled. This AI-powered television, featuring voiceprint recognition technology, is designed to offer a more interactive and personalized experience. The TV's ability to recognize users through their voice and tailor content accordingly has caught the attention of industry experts and consumers alike.
According to an industry insider who tested the device, "In a few years, as deep learning-based AI becomes more widespread in smart TVs, people will truly appreciate the value that the CHiQ TV Q5K brings. Voiceprint recognition allows the TV to identify users accurately and deliver content that matches their preferences."
While many smart TVs today rely on basic voice control, the real potential of AI lies in deeper integration, such as natural language processing and intelligent data analysis. The CHiQ TV Q5K goes beyond simple voice commands by incorporating advanced technologies like far-field speech, voiceprint recognition, and fuzzy retrieval. These features enable the TV to understand user intent, adapt over time, and even interact with other smart devices in the home.
With a voice recognition accuracy rate exceeding 97%, the TV can distinguish between different family members and provide personalized recommendations. For example, if a user says "Sun Wukong," the built-in AI assistant, Xiaobai, can suggest related content like "Journey to the West" or "The Three Battles with the White Bone Spirit."
Industry experts noted that the CHiQ TV Q5K stands out from conventional AI TVs due to its advanced logical reasoning and computational capabilities. During a comparison test with five other AI TV models, it was praised for its superior performance and user experience.
Behind the CHiQ TV Q5K is a strong AI technology system developed by Changhong. The voiceprint recognition technology, originally created by Changhong’s AI Lab, uses I-vector and PLDA techniques to build unique voice profiles for each user. Combined with cloud computing, this enables accurate identification and personalization.
Supported by a comprehensive data platform, the three core technologies are powered by four key algorithms: semantic understanding, retrieval, recommendation, and data mining. These allow the TV to not only interact with users but also grow and evolve based on their behavior.
To ensure seamless operation, Changhong has integrated various resources, including big data, cloud computing, AI R&D, smart manufacturing, and IoT platforms. This creates a full industrial chain centered around innovation and user-centric design.
As one industry observer stated, "Products like the Apple iPhone, Gree air conditioner, and Changhong TV are all backed by strong supply chains and technological collaboration. The evolution of Changhong’s AI technology points to the future direction of the home appliance industry, where intelligence will become more sophisticated and deeply embedded in daily life."
Modular UPS Power Supply
The categories of Modular UPS Power Supply are described as follows:
I. Definition and overview
Modular UPS power supply is a design architecture that divides the UPS system into multiple independent modules. Each module contains complete power conversion functions, such as inverters, rectifiers, batteries and control circuits, and can be operated independently, and modules can be added or reduced according to demand to adapt to different load requirements. This design improves the flexibility, reliability and maintainability of the UPS system.
Second, the main composition
Modular UPS power supply usually consists of the following main components:
Rack: The infrastructure that supports and holds each module.
UPS power module: Contains core power conversion components such as inverters, rectifiers, and chargers, which are responsible for converting input mains or battery power into stable AC power output.
Static switching module: Switches between mains and inverter output to ensure continuity of power supply.
Display communication module: Provides user interface and communication interface for monitoring UPS status and remote management.
Battery pack: Provides backup power to the UPS system to ensure continuous power supply in the event of a mains interruption.
Iii. Characteristics
Scalability:
Modular UPS allows the flexibility to expand or shrink system capacity based on load demand, by increasing or decreasing the number of modules.
Redundancy:
Each module has independent power and control functions, so the system is highly redundant. When one module fails, the other modules can continue to work, ensuring the continuous power supply of the load.
High reliability:
Due to the modular design, fault isolation is easier, and the failure of one module will not affect other modules, thus improving the reliability and availability of the entire system.
Simplify maintenance:
Modular design makes maintenance easier. When a module needs to be serviced or replaced, it can be done separately without the need to shut down the entire system, reducing maintenance time and interference with the load.
High performance:
Modular UPS systems typically have a high energy utilization rate, with the ability to adjust the number of modules according to load demand to provide greater efficiency. (
Intelligent management:
Many modular UPS are equipped with intelligent management systems, which can monitor the status of power supply, battery status, load, etc., and have fault diagnosis, automatic switching, remote monitoring and other functions.
