In the wave of intelligent operation and maintenance of industrial equipment, Yubo Technology once again led the industry breakthrough-a new generation of 144-channel acoustic imager was officially released. As the founder of domestic industrial acoustic imaging technology, with the core concept of "hearing more clearly, measuring more accurately and resisting interference", we increased the number of microphones from 128 to 144, broke through the bottleneck of the industry, and expanded the frequency range to 100kHz, fully benchmarking the performance of international first-line brands, and providing revolutionary detection solutions for electric power, petrochemical, intelligent manufacturing and other fields.
1. Hardware upgrade: 144 Microphone array reconstruction detection accuracy
Breakthrough of sound source localization:
The spiral layout of 144 high-sensitivity MEMS microphones and the beamforming algorithm are used to realize the accurate positioning of 0.5 angle deviation. Compared with the previous 128-channel model, the sound field coverage density is increased by 12.5%, and more than three sound sources can be identified at the same time, especially in the 100-meter long-distance detection, the angle deviation is less than 1, which completely solves the problem of "multiple sound sources confusion" of traditional equipment.
Leak detection is more sensitive:
The detection limit is increased by 50% compared with the previous generation, and the tiny leakage of 0.0045L/min can be identified at a distance of 2.5 meters and a pressure of 1.2bar. The AI algorithm quantifies the leakage cost in real time. For example, when a leakage of 0.032L/min is detected, the annual loss is automatically calculated to be about 1,200 USD (estimated according to the industrial electricity price of 0.1 USD /kWh).
Second, technological innovation: 100kHz ultra-wideband and anti-interference double breakthrough
Full-band fault capture:
The frequency range is extended from 65kHz to 2kHz~100kHz, covering the detection of compressed air leakage (20kHz~40kHz), partial discharge (1kHz~10kHz) and mechanical abnormal sound (low frequency band). In the actual measurement of a chemical scene, the 0.0032L/min benzene vapor leakage caused by valve seal failure 200 meters away was successfully located, and the explosion risk was avoided by combining the explosion-proof design.
Anti-interference in complex environment:
Equipped with adaptive beamforming technology and dynamic noise suppression algorithm, the signal-to-noise ratio is improved to > ＞30dB in the factory workshop with background noise > ＞80dB, effectively filtering interference signals such as mechanical vibration. The temperature, humidity and air pressure compensation module can work stably in the wide temperature range of-20℃~50℃, and its environmental adaptability is superior.
Third, scene adaptation: comprehensive coverage of multi-dimensional detection capability
Deep diagnosis of power system;
It supports PRPD spectrum analysis, and can identify weak discharge signals ≤10pC, with a false alarm rate of less than 2%. The actual measurement of a provincial power grid shows that the inspection time of substation is shortened from 3 days for a team of 10 people to 6 hours for one person, and the cost of single inspection is reduced by 70%.
Safety escort of petrochemical industry;
In the inspection of LNG storage tanks, the methane leakage of 0.13ml/s (pressure of 0.6MPa) is accurately located 200 meters away, and the report of leakage rate and annualized cost is generated synchronously, which is directly connected to the enterprise asset management system (such as SAP).
Intelligent manufacturing efficiency revolution:
An automobile factory saves more than $4,000 annually by detecting compressed air leakage. In the wind farm scene, the abnormal sound of gearbox is identified 100 meters away, and the life decay curve of equipment is predicted, thus realizing the transformation from "fault maintenance" to "health management".
Fourth, the industry benchmark: domestic technology is comparable to the international front line.
Yubo Technology has been deeply involved in the field of acoustic imaging for many years, and its core technological breakthroughs include:
Algorithm autonomy:
The self-developed AI sound source classification model can distinguish four types of partial discharges, such as tip discharge and suspension discharge, with an accuracy rate of 98%, and its performance is at the forefront of the international standard.
Domestic substitution:
The core devices are 100% localized, and the equipment cost is only 1/3 of that of imported brands. At the same time, it has passed IP56 protection certification and CE/FCC electromagnetic compatibility test, and the quality system is in line with international standards.
Multimodal extension:
640×512 infrared thermal imaging module can be selected to realize "double verification of sound and heat", and simultaneously analyze temperature anomalies and acoustic signals, such as temperature difference detection caused by valve internal leakage, and the diagnostic efficiency is improved by 40%.
Fifth, open a new era of industrial testing accuracy
The release of 144-channel acoustic imager marks another technological leap of Yubo Technology in the field of industrial detection. With the mission of "hearing more clearly, measuring more accurately and resisting interference", we use domestic innovative technology to break the international monopoly and provide a solid guarantee for the transformation and upgrading of China manufacturing.
