On September 20, the 2023 Fortune China Best Design List was officially announced, and iFLYTEK acoustic imager won the list with its industry-leading microphone spiral array technology and sound source localization algorithm, innovative industrial AI multi-dimensional design, and diversified industrial scene applications.
This is the second time that Fortune has released China's Best Design List, focusing on excellent design works with business prospects or social influence that start from people's real needs, try to solve complex problems, and apply for them all industry leaders, covering a wide range of industries. As the first self-developed visual sound source positioning equipment independently developed by iFLYTEK, iFLYTEK acoustic imager stands out from more than 200 enterprises participating in the application due to its advantages in technology, design, prospect and social responsibility, and has become one of the best designs of Fortune China.
iFLYTEK acoustic imager can be successfully listed without strong technical support. iFLYTEK has always adhered to the core technological innovation of the source, and has successively won the championship of DCASE 2020, 2022 and 2023 International Authoritative Industrial Voiceprint Challenge. DCASE is currently the most authoritative competition in the field of sound events, and iFLYTEK has achieved the first place in the track of sound event localization and detection for two consecutive times.
In 2022, under the conditions of low resource training volume and real test set, iFLYTEK proposed a scheme including data enhancement, long-term and short-term modeling and model structure optimization to create the strongest system for sound event localization and detection. In 2023, iFLYTEK further proposed a method of fusing sound separation to solve the problem of poor prediction accuracy under high overlap rate, reduce the impact of uneven distribution of duration distribution and sound source distance, reduce the detection error of far-field, small sound, and low frequency sound categories, so that the machine can accurately separate and distinguish sounds like the human ear. iFLYTEK applies sound positioning and detection technology to acoustic imagers, breaks the monopoly of key foreign technologies, promotes the landing of localized technology, and launches the first self-developed visual sound source positioning equipment in China to achieve domestic substitution.
iFLYTEK acoustic imager innovatively integrates hearing and vision, converts sound information into visual images through conversion design, and presents the detection results in the form of acoustic images, so that the location of the sound source is "clear at a glance" and warns of possible problems in the equipment in advance. Traditional industrial inspection products can usually only process single-modal numerical data such as temperature and vibration, which has certain limitations in data collection and analysis applications. iFLYTEK acoustic imager supports multi-modal perception such as sound, image, and infrared, which can convert high-frequency sounds beyond the human hearing range or extremely fine vibrations that cannot be noticed by inspectors into intuitive images, realize information conversion between multi-modalities, and improve information processing efficiency. iFLYTEK acoustic imager makes full use of the multi-dimensional design concept of industrial AI, focuses on the design innovation of AI products in industrial scenarios, and brings users a more intelligent product experience.
At present, iFLYTEK acoustic imager has achieved practical application results in electric power, steel, chemical, gas, mining and other industries, helping intelligent operation and maintenance detection.
In the power industry, the partial discharge of the insulator joint of a substation line was successfully detected, and the hidden dangers of the equipment were discovered in time, and the patrol efficiency was improved by more than 60%.
In the steel industry, the vacuum of 12 sealed branch pipes of a sintering plant was quickly swept and 22 gas leakage points were detected, helping customers realize all-round detection of vacuum leakage points for the first time, and incorporating vacuum leakage into the subsequent normalized maintenance content.
In the chemical industry, in a petrochemical enterprise, 9 suspected leakage points such as flanges, valves and pipe elbows were found in two operating areas in 20 minutes, which were verified by gas flow detectors to be 100% accurate.
In the gas industry, gas leakage detection on a CNG filling station station, flanges, valves and other leakage points were found within 30 minutes, and the gas flow detector verified 100% accurate, if the traditional manual soapy water method of detection takes at least 5 hours.
In the mining industry, gas leakage at the interface of the compressor fan pipeline in the machine room was successfully detected in a mine, which achieved fast and accurate positioning in the high-noise environment of the coal mine and reduced the workload of inspection personnel.
At the Hangzhou Asian Games, iFLYTEK acoustic imager also "showed its talents" to help the safety of gas in the Asian Games Village. In order to better maintain the operation safety of the Asian Games Village and ensure the safety of gas use, iFLYTEK acoustic imager is used in the Asian Games gas guarantee work. The inspectors confirmed the leakage point through the equipment, notified the maintenance personnel to the scene to carry out maintenance in time, eliminated the fault, so that the gas leakage could not be hidden, and ensured that the Asian Games were foolproof.
iFLYTEK is committed to "using artificial intelligence to improve industrial efficiency", and has created a series of industrial six-sense products represented by iFLYTEK acoustic imager, so that the industrial production process has the intelligent perception ability of "hearing, smelling, touching, and thinking", which not only solves the problems of equipment management and safety detection in the industrial field, but also effectively promotes social development.
