Sound source localization is a basic method for human and animal perception of the environment. The human and the animal determine the spatial position of the sound source through the auditory system, including determining the volume, position, distance, and the like of the sound source to sense the motion of the sound source. However, due to the limitations of our visual range of the naked eye, it is impossible to obtain the specific distribution information of the sound source.
With the development and popularization of information technology, an acoustic innovation technology that simulates a biological sound source localization system was born and played a vital role in many military and civilian systems. Sound source localization and imaging technology combines expertise in acoustics, signal detection, digital signal processing, electronics, software design, etc., by processing the received sound source signals, determining the geometric position of the sound source based on the data, and generating space in real time. The sound field distribution cloud image has a wide application prospect by visually reflecting the intensity and distribution of the sound through the color and brightness of the image display.
Qingyin Acoustics enters the illegal whistle capture market through acoustic innovation
Qingyin Acoustics has its own advantages in production and research in the field of acoustics, from algorithm to software, from research and development, design to production, fully independent development, fusion of Pod Directional locating technology, beam forming technology and automatic noise suppression technology, and innovative sound source localization. And sound imaging technology, applied to the illegal whistle capture system, to achieve illegal whistle visualization, to help the traffic police quickly and efficiently enforce the law, to provide a scientific basis for the control of illegal whistle.
Clear listening acoustics illegal whistle capture system has experienced countless calculations and experiments. Through repeated refinement and fine algorithm, the detection width can cover 5 lanes, the effective detection distance can reach 50 meters, and the comprehensive accuracy rate is up to 95%. Capture the best in the industry.
| Qing listening acoustics illegal whistle capture system is technically refined and upgraded
Qing listening acoustic illegal whistle capture system through a large number of sound source data acquisition, continuous deep learning, can accurately analyze the characteristics of voiceprint, automatically eliminate the ambient sound interference such as brakes, engine, tire noise, electric car horn, real-time detection of vehicle whistle Quickly locate the whistle vehicle, automatically carry out license plate recognition, capture and vehicle tracking, real-time generation of audio-visual maps, whistle vehicle information maps, audio and video evidence, online completion of evidence upload and storage, seamless access to traffic police Some traffic violation monitoring systems are eventually pushed to mobile devices such as mobile phones of law enforcement personnel. The whole process is done in one go, and it takes less than a millisecond.
Qing listening to the acoustic illegal whistle capture system through the Ministry of Public Security authoritative testing and certification, assisting the China Institute of Metrology to develop verification procedures and industry standards, forming industry norms.
| Qing listening acoustics illegal whistle capture system installation and maintenance faster
Qing listening to the acoustic illegal whistle capture system can be installed in schools, office buildings, residential areas and other key banned areas, single-pole installation, very convenient. Due to the core technology of Qingyue Acoustics illegal whistle capture system, it is fully self-developed and has active selectivity. It can flexibly adjust the installation scheme according to the scene requirements, with higher degree of fit and higher work conversion rate.
