There’s no limit to creativity, and innovation knows no bounds. Today, we’re introducing a national invention patent for an intelligent display sensor water meter. This patent was applied for by Zhengzhou Single Point Technology Software Co., Ltd. and was officially authorized on July 18, 2017.
This utility model focuses on an intelligent display induction water meter, which falls under the category of water meter technology. A water meter is essentially a device used to measure water flow, typically for cumulative flow measurement. Water meters are generally categorized into two types: volumetric water meters and velocity water meters. The former has higher accuracy compared to the latter, but its performance can be affected if the water quality is poor, as impurities may clog it. These meters are usually installed on water pipes to record water usage when users release water. The pointers or character wheels on the meter then indicate the amount of water consumed.
A smart water meter represents a new generation of water meters that leverage modern microelectronics, sensing technologies, and smart IC card technology to measure water consumption and facilitate data transmission and settlement transactions. However, existing water meters often rely on external power sources for their intelligent controllers, which consume significant amounts of energy, leading to unnecessary waste.
To address these issues, this invention provides an intelligent display sensing water meter. It includes a water inlet housing, a total control valve, a water flow detection sensor, an electric housing, a signal converter, an intelligent controller, a communication module, a display screen, a power module, and a card sensor. There’s also an impeller, a generator, and a sealing ring involved.
An inlet pipe is installed on the water inlet housing, with a total control valve located at the water inlet of the pipe, and a water flow detection sensor on the outlet. Inside the water inlet housing, there’s an impeller whose rotating shaft connects to the generator's rotating shaft via a sleeve. The generator's rotating shaft is mounted on the housing using a sealing ring.
Above the water inlet housing sits an electric housing, housing a signal converter, intelligent controller, communication module, and power module. A display screen and card sensor are mounted on the exterior of the electric housing. The intelligent controller's power terminal connects to the power module, while the generator’s output is electrically connected to the power module's charging end through a wire. The water flow detection sensor is linked to the signal converter via a signal line. The signal converter and card sensor connect to the intelligent controller’s input end through wires, and the controller’s output connects to the main control valve and display. Additionally, the communication terminal of the intelligent controller is electrically connected to the communication module.
Preferably, the card sensor’s outer surface features an inductive marking layer, and the display screen is an LED display. This design offers advantages such as efficient energy utilization, energy savings, ease of use, simplicity of operation, and high work efficiency.
In conclusion, this innovative water meter represents a leap forward in water meter technology, offering numerous benefits over traditional models.
Multi Channel Amplifiers
Multi-channel amplifiers build on the advanced foundation of digital amplifier modules, taking audio amplification to new heights by enabling the simultaneous processing and amplification of multiple audio signals. These amplifiers are designed to meet the complex audio demands of modern applications, offering enhanced flexibility and superior sound quality.​
Multi-channel amplifiers are specialized audio devices designed to drive multiple speakers or speaker systems simultaneously, delivering precise control over sound distribution in complex setups. They are widely used in home theaters, professional audio installations, automotive systems, and commercial venues, offering flexibility and scalability for diverse audio needs.
Working Principle:​
Â
At the core, multi-channel amplifiers utilize multiple digital signal processing (DSP) paths, each corresponding to a separate audio channel. Similar to digital amplifier modules, the incoming analog audio signals for each channel are first converted to digital format by individual Analog-to-Digital Converters (ADCs). Subsequently, the DSPs for each channel perform dedicated operations such as independent filtering, precise equalization tailored to specific audio sources, and customized reverb settings. After the digital processing, Digital-to-Analog Converters (DACs) transform the signals back to analog, and the output stage amplifiers power the corresponding speakers for each channel. This independent processing for every channel ensures that each audio stream maintains its integrity and clarity, even in complex multi-source setups. For example, in a 5.1 surround sound system, the multi-channel amplifier can handle the distinct audio information for the left, right, center, left surround, right surround, and subwoofer channels with precision, creating a rich and immersive soundscape.
Advantages:
Multi-channel amplifiers are essential for creating immersive, balanced audio environments, combining technical versatility with user-friendly design for both professional and consumer applications. ​
Enhanced Audio Separation and Immersion：By providing individual amplification for each channel, multi-channel amplifiers achieve unparalleled audio separation. This allows for a more accurate placement of sound elements in the audio field, creating a highly immersive listening experience.  ​
Flexible Configuration and Scalability：These amplifiers offer great flexibility in configuration. Users can easily adjust the settings for each channel, such as volume, tone, and balance, according to their specific needs. Moreover, many multi-channel amplifiers support modular designs, enabling seamless expansion. Â
Efficient Power Management：Leveraging the energy-efficient technologies of digital amplifier modules, multi-channel amplifiers optimize power usage across all channels. Even when handling multiple audio streams simultaneously, they maintain high efficiency, reducing energy consumption and heat generation.
