Exploring the commercialization opportunities of LED white light communication
LED white light communication for indoor positioning has always been the focus of research and development personnel at home and abroad. Nowadays, not only has the technology made great progress, but China has also taken the lead in realizing commercial operation. Recently, the world's first U-beacon system based on LED white indoor positioning technology commercial operation APP is the first to complete the process from technology to commercialization, becoming the world's first indoor realization of visible light communication commercial operation and indoor 3D real map Positioning Technology. Once the news was announced, it quickly attracted widespread attention and heated discussion from the industry and major media. This technology allows us to see hope. From the perspective of technology and commercialization, China is at the forefront of the world, which has increased our confidence. A senior technical expert is full of excitement, not only that, but the technology will also provide greater help to the traditional retail industry. Indeed, in the context of the rapid expansion of e-commerce and the transformation of traditional retail, O2O has become a hot spot in the industry, and indoor positioning technology that combines navigation, shopping guide, search, games, social and other functions is undoubtedly for large-scale business. Projects (such as shopping malls, supermarkets) and so on are of great significance. Undoubtedly, China's indoor positioning technology has ushered in an unprecedented development opportunity, but despite this, this new technology still faces challenges and difficulties in the process of commercialization, how to meet challenges, overcome difficulties, and its application prospects have become common in the industry. The focus of attention. What is white light indoor positioning? Want to understand the optical positioning, but also from the LED white light communication technology. Fu Qiang, deputy secretary general of the National Semiconductor Lighting Engineering R&D and Industry Alliance, said in an interview that in fact, optical positioning technology is realized based on LED white light communication technology. LED optical positioning technology is an important direction of Visible Light Communication technology. It is an emerging communication technology based on location service (LBS-Location-based Service), which utilizes the relevant characteristics of visible light lines such as LEDs to realize information exchange between intelligent terminals of lighting fixtures. It has been developed by the developed countries of the world for many years. According to experts, the principle of LED white light communication technology is mainly to compile the information to be transmitted into a special signal, and attach the signal to the driving current of the LED lamp by pulse width modulation method, so that the LED lamp flashes at a very high frequency. After the high-frequency flicker that is invisible to the naked eye is detected by the photosensitive device, it is restored to the information to be transmitted, thereby achieving the purpose of information transmission through the luminaire. Fu Qiang told reporters that Baiguang communication technology can use every indoor lighting fixture as a positioning reference point, just like the satellite in the GPS system to achieve accurate indoor positioning. Its accuracy and reliability are obvious compared to other indoor positioning technologies. Advantage. This technology is not only a revolution in intelligent lighting, but also effectively solves the worldwide problem of indoor precision positioning. What is more worth mentioning is that China's pace is faster than other countries. The above experts said. In this regard, Fu Qiang is also excited to say that in recent years, the giants of various countries have never stopped researching and developing LED white indoor positioning technology, but the good news is that China has achieved remarkable results in this technology, not only launched. The self-developed indoor positioning system, and also realizes the commercial operation of the system. At present, only one American company has mastered the same kind of technology, and they only have prototypes. Now they can only be used for exhibitions, and we have successfully developed products that can be directly applied. Yang Feng, chairman of Huace Group, is also very proud to say. It is understood that as a project of cooperation with the National Key Laboratory of Semiconductor Lighting Innovation, Huace Optical Communication Technology Co., Ltd. (hereinafter referred to as Huace Optical Communication) independently developed the U-beacon indoor positioning system based on LED white light positioning technology. An indoor positioning system with practical application value on a global scale. U-beacon indoor positioning system mainly uses CMOS camera for visible light signal reception, which really makes up for the shortcomings of other countries that are susceptible to interference from other surrounding light sources in terms of visible light signal reception. The above experts pointed out. According to Fu Qiang, U-beacon indoor positioning system is the second generation of Huace Optical Communication. The system can be applied to indoor positioning and navigation of large-scale commercial projects, public facilities, etc., and the business prospect is very broad. What are the advantages of the U-beacon positioning system? Fu Qiang told reporters that most of the existing indoor positioning technologies use Bluetooth, WiFi and other wireless signal strength estimation distance to achieve positioning, while U-beacon positioning system solves the hardware adaptation problem very well, and can directly use the user's smart phone as The optical signal receiving end, and the user only needs to install an application software on the mobile phone without adding any hardware.
