What if our headlights can interact with mobile devices such as mobile phones and help you pinpoint and push information? On September 4th, at the 15th China International Optoelectronic Expo, the reporter noticed that white light communication technology based on LED light source is becoming more and more mature, relying on safer, more accurate and lower cost positioning technology, or will replace traditional wireless and WiFi. Positioning Technology.
Zhuhai Huace Optical Communication Technology Co., Ltd., which exhibits this technology, introduces LED white light communication as a technology that compiles information into signals and transmits high-frequency flicker signals through LED light sources. The flashing signal is not visible to the person, but can pass through the receiver. It can be received by mobile terminals such as mobile phones, and the technology can be used for positioning, navigation, and the like.
“For example, in underground mines, wireless transmission is used to locate workers with inaccurate positions, and it is easy to generate electric sparks. It is not safe. The new technology only needs to install small devices for the light source in the mine and the headlights of the miners, so that it can be accurate for all workers. Positioning, Fu Qian, general manager of Huace Optical Communication Technology Co., Ltd., said that this positioning method will be lower than the cost of wireless positioning system by more than half.
At the scene, the technician used a mobile phone equipped with a special APP to demonstrate, holding the mobile phone in the venue, the system quickly showed the movement of its position, and only 1 meter of movement can be displayed. "The accuracy of traditional GPS positioning is 30-50 meters. It has no meaning in a small indoor range. The positioning accuracy of WiFi can only reach 30-50 meters, and the positioning accuracy of white light communication technology can reach 1 meter." Fu Qiang said. This means that this positioning and navigation in the mall can be precise to the specific store.
It is understood that this technology has developed "downhole personnel positioning system" and "Ubeacon indoor navigation system". The person in charge of Huace Optical Communications introduced that the current project plans to spend 2 billion yuan to build the LED white light communication project headquarters in Hengqin New District of Zhuhai.
