Recently, the world's first indoor high-precision audio positioning chip based on RISC-V architecture was released in ZJZL Chip Technology Corporation. Experts said that this means the realization of the "Made in China" audio positioning chip, a pioneering Chinese solution for indoor high-precision positioning, which not only possesses international competitiveness, but also rises from a "follower" to a "leader".
This is a dedicated chip for audio ranging, with super-strong audio signal processing performance and complete audio positioning processing capabilities.
As we all know, although navigation is convenient now, directions are often not found in high-speed rail stations and terminal buildings, indoor parking lots will fail, and in large shopping malls, it is even more difficult to know which floor is located… These "pain points" are all reflected. The importance of indoor high-precision location services. At present, this technology has been tested in different scenarios such as Nanjing South Railway Station, Baiyun Airport, and China International Exhibition Center, and has achieved good application effects.
The indoor high-precision audio positioning technology independently developed by the ZJZL team has broken through the key indoor high-precision positioning technology of consumer-grade smart terminals. It has completely independent core intellectual property rights. It has independent controllability, precise positioning, easy deployment, mobile phone access, unlimited concurrency, Six features such as privacy protection.
High-precision, small-scale, and low-power chips are currently the highest pursuit of the industry. "Sound is a signal, and audio positioning is like an indoor Beidou satellite navigation system, allowing high-precision positioning to achieve seamless switching from outdoor to indoor." National High-level Talent Distinguished Expert, Academician of the Finnish Academy of Sciences and Humanities, Wuhan Said Chen Ruizhi, director of the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing at the University.
At the press conference, ZJZL also simultaneously released core modules and special modules based on audio positioning chips, and provided developers with corresponding development boards, development kits and software development support packages for the audio positioning core engine. "It is precisely because of 6 years of accumulation that positioning chips can take a huge step forward." Chen Ruizhi said proudly.
The technological breakthrough of positioning chip has huge economic and social benefits. Speaking of future development, Chen Ruizhi said that the key R&D project of the Ministry of Science and Technology "High-availability and high-precision indoor intelligent hybrid positioning and indoor GIS technology" and its related outstanding scientific and technological achievements will be incubated in the industry, so as to create an internationally leading high-tech industry in China. Accurate indoor positioning technology.
