Allinby attended the China Aviation Equipment Data Intelligence Test and Industrial Development Conference to demonstrate its acoustic strength

Issuing time:2024-04-01 13:55

On March 28, 2024, the China Aviation Equipment Data Intelligence Test and Industrial Development Conference was grandly opened in Mianyang, Sichuan Province, attended by domestic and foreign experts and scholars in the field of aerospace and representatives of leading enterprises in various fields. As a leader in acoustic sensor technology in China and the only acoustic sensor exhibitor, Allinby was invited to attend the conference for the first time to show its strength in the field of acoustics.

Le Jialing, academician of the Chinese Academy of Engineering, delivered a speech at the conference and said: "This conference will focus on aviation equipment, digital intelligence testing and aviation industry development, grasp the key nodes of national industrial digital transformation and upgrading, and promote the comprehensive and rapid transformation of China's aero engine design, testing and production to the direction of 'digitalization, networking and intelligence'." He said that he hoped that through this conference, he could further deepen the understanding of aviation data intelligence tests, jointly promote the rapid iterative development of the aviation engine industry, and create a stronger "Chinese heart".

During the conference, the company's booth attracted the attention of many participants, who showed a strong interest in the acoustic sensor products made by the company to break the international monopoly and achieve localization. In the active noise reduction exhibition area, the related products of Allinby's active noise reduction of 10-20dB made the experiees personally feel the remarkable effect of noise reduction technology. According to the reporter, a number of aviation industry customers have shown interest in Allinby, and said that the follow up will find specific scenes for introduction trials.

Breakthrough technology to break the international monopoly, a number of acoustic sensors appeared


In addition to active noise reduction technology, the company also presented a series of innovative acoustic microphones in the field of acoustic sensor technology, including 2.5mm ultra-thin surface microphones, high temperature resistant microphones up to 400 degrees Celsius, microphones that measure high sound pressure levels of 184dBA, and ultra-short array sensors with a length of only 30 mm. It not only breaks the monopoly of international manufacturers in related fields, but also provides strong technical support for the autonomy of domestic high-end equipment, especially in the aerospace field, showing great application potential.

According to the reporter, Allinby 2.5mm ultra-thin surface microphone is currently the only domestic product to achieve this ultra-thin technology. The product adopts a new ultra-thin design and advanced packaging technology, the thickest part of the entire microphone is only 2.5mm, which minimizes the impact of air resistance on sound measurement, provides a professional measurement tool for the surface sound measurement of high-speed aircraft in the aerospace field, and breaks the monopoly status of the ultra-thin surface microphone field which has been dominated by foreign brands. It has laid a solid foundation for the localization of China's high-end test and measurement equipment.

The high temperature resistant microphone realizes the accurate measurement of sound in some very special ultra-high temperature environments. Relevant staff told reporters that the special material can work normally at extreme high temperatures of up to 400 degrees Celsius, providing reliable measuring equipment for the noise measurement of aircraft engines. It is an important basis for aero engine design evaluation, fault warning and diagnosis and life prediction.

Aerospace professional solutions to help the aerospace industry develop in high quality



In addition to acoustic sensor products, the company also showcased its specialized acoustic solutions, such as temperature field measurement solutions based on acoustic technology and pipeline leakage solutions using acoustics. These schemes have been widely used in the power generation industry, and have shown new application prospects in many fields such as aerospace.

For example, using the principle that sound travels at different speeds in media of different temperatures, Allinby offers a non-contact, acoustic-based solution for temperature field measurement. This solution can measure the temperature field from minus 200 degrees to 2,500 degrees with a temperature measurement error of less than 1%. After years of technology promotion and iterative upgrading, this temperature field measurement technology has been widely used in the power generation industry, and more than 10 power plants such as National Energy Group and Huadian Group have been widely recognized by customers. This technology can also be applied to the field of aerospace, providing a new research direction for the measurement of the temperature field of aero-engine and rocket launch flame.

The acoustic pipeline leakage solution is to collect signals on the surface of the pipeline, use wireless transmission to summarize the data, and then use the algorithm based on the general large model to process the data, and finally give the accurate location of the pipeline leak point. This solution can accurately locate the leakage situation of different materials (carbon steel, stainless steel, PVC, etc.), and the location of the leak point can be accurate to the meter level. The staff told reporters that this system helped Tianjin University quickly locate more than 150 leaky spots on the campus that had been unable to be found for many years, saving more than 2.6 million wasted water charges annually, and investing in the recycling system within one year.

These innovative products and solutions in the field of acoustic sensors demonstrate the company's leading technical strength and innovation ability in the field of acoustics in China. In addition, Allinby also actively conducted in-depth exchanges and cooperation with other enterprises, experts and scholars at the conference. By sharing experience, discussing technical problems, and exploring joint research and development of new products, Allinby continues to expand cooperation areas and enhance technological innovation capabilities.

Allinby co-founder Li Hao told reporters: "Allinby has accumulated technology in the field of acoustics for more than 10 years, we have provided more than 2,000 customers with high-quality acoustic, vibration and related products and services, and accumulated acoustic sensor shipments of more than 100,000 units. In the future, Allinby will continue to exert its experience and technology in the field of acoustics and vibration to provide more solid support for promoting new industrialization, accelerating the formation of new quality productivity, building a manufacturing power, and contributing new vitality to Chinese-style modernization."
