LED light source for mobile terminal positioning

If the top of the lamp can be lit by the mobile phone and other mobile terminals such as mobile terminals to interact with the information, and help you pinpoint and push information, our life will be like? Yesterday, the fifteenth session of the Chinese International Optoelectronics Expo opened in Shenzhen, the exhibition of the first set of LED lighting museum experience, and concentrating communication products and production and processing technology, laser technology, laser and optoelectronics, machine vision, infrared test and measurement technology, LED lighting and display a full range of content industry. At the exhibition, the reporter noted that the white light communication technology based on LED is maturing, relying on more secure, more accurate and lower cost positioning technology, or will replace the traditional wireless and WiFi positioning technology.

With the deepening of various fields of photoelectric production and scientific research and life, has been held in Shenzhen for 15 years Chinese light Expo this year will continue to expand the exhibition area, and covers all the exhibition hall of Shenzhen Exhibition Center, the exhibition area of 110 thousand square meters, each field of comprehensive coverage of optoelectronic applications. The reporter learned from, held for the first time since Chinese CIOE brought together industry leaders and technical elite, all-round display industry all kinds of novel design, advanced technology, innovative product solutions and new effective in keeping with the trend of application technology, has grown into the top show China and global photoelectric field.

At the exhibition site, the reporter noted that the emerging communications technology - Location-based services in the white light communication technology, in the venue by domestic and foreign counterparts and experts. This display technology Zhuhai Huace optical communication technology company, LED communication information is compiled into a white light flashes emit high frequency signal transmission signal, the LED light source technology, people are not visible flicker signal, but can be received by a mobile terminal receiver and mobile phone, technology can be used for positioning, navigation and other purposes.

For example, in the underground mine, using wireless transmission mode positioning workers imprecise location and easy to produce spark, not safe, small device with new technology only for the mine in the light source and the miners headlights, can accurate positioning for all workers, "Hua Ceguang communication technology company general manager Fu Qiang introduction, this location will more than half of low cost wireless positioning system.

At the scene, the technical staff with a dedicated APP mobile phone demo, holding the phone to move around the venue, the system will soon show the movement of its location, and only 1 meters of mobile can also be displayed. "The traditional GPS positioning accuracy is 30 - 50 meters, in the indoor small range has no meaning, the precision of the WiFi can only reach 30 - 50 meters, and white light communication technology positioning accuracy can reach 1 meters," Fu Qiang said, which means that in the mall the positioning and navigation can be accurate to a specific store. It is understood that this technology has developed a "underground personnel positioning system" and "Ubeacon indoor navigation system". Hua Ceguang communications responsible person, at present the first phase of the project plans to spend 2 billion yuan in the construction of the Hengqin new area of Zhuhai LED white light communications project headquarters.
