10 yuan to achieve things?

For hardware, what is intelligence?

Mass media will often be so defined: hardware products on the phone APP even intelligence.

The students in the "terryoy" smart "bondage" in this article is that: when people cut scenes of life, the primary consideration is how to serve the people, can help people quickly analysis and judgment, in certain scenarios, decided to solve the problem is really smart.

In accordance with the above two definitions, the following to be introduced in this product is also regarded as intelligent hardware, but it only spent more than $10 on the original LED lights, it is completed to the smart change.

This project is called U-Beacon, people can use it to achieve accurate positioning of indoor commercial establishments.

The U-Beacon Team Office, responsible person Tang Haijun told the author demonstrates this positioning technology: only he took out his mobile phone, open APP, front camera alignment of the roof lighting, after a few seconds, the mobile phone appeared location information.

"What is this principle? Does this light look exactly the same as the normal LED? The author asked curiously.

Ha ha, this thing is fun, you also look at the front camera to the lamp. Tang Navy said with a smile.

After I did so, the door to a new world was opened, seemingly ordinary LED lights in the phone shows a flashing black line".

"This is not the same as we usually scan the principle of two-dimensional code? I asked.

"It can be understood, but our 'two-dimensional code' is invisible to the naked eye. "

Visible light communication technology, also called LED white light communication technology, technology principle is to compile will need to transmit information into a modulated signal, attached to the drive current of LED lamp with pulse width modulation, as the carrier of the light source emitting indoor everywhere, when the user enters the lighting area, not to increase any hardware the intelligent mobile phone receiving and identifying the optical signal, the only parse out the identification information sent by the identification lamps, the information to determine the corresponding position information on the map database, complete positioning.

But we already have the life of GPS, WIFI, Bluetooth, such as the transmission of indoor positioning system, visible light communication technology and the meaning of where?

For this problem, Tang Haijun gives the answer is this:

Now more and more large shopping malls have an area of more than 100 thousand square meters, when more and more large indoor space, we have supplemented by the task of indoor positioning system will be a large error. Whether it is GPS or WIFI, or Bluetooth, technical defects, especially in terms of accuracy is very obvious. GPS positioning accuracy of 10-100 meters, and also have to be affected by the environment, the need for multi-point positioning and data matching can be completed, the reaction rate is relatively slow. Although WIFI and Bluetooth technology is relatively mature, but the principle through the wireless signal dependent mobile phone, WiFi wireless network in the air by measuring the attenuation of the wireless signal strength attenuation distance to determine the indoor location, the wireless signal attenuation is affected by the environment inside the building in the air, there is no way to the positioning accuracy of less than 5 meters, so the location is very imprecise. And it is precisely because of these defects in other positioning, visible light communication technology has the meaning of existence.

High speed light flashing signal with LED lights on the visible light communication technology can make the invisible, these signals can be used not only to transmit information, and if you can locate it, positioning accuracy can reach 1 meters. In the eyes of the U-Beacon team, which is to solve the positioning precision of the ideal scheme of war.

Prior to the U-Beacon, the U.S. Bytelight team has completed financing through a similar technology, and cooperation with lighting manufacturers, into the actual production. But U-Beacon "steps" obviously step more, their equipment 3D 360 real map using APP - easy to visit, to establish a mature online community through it, to build a O2O platform, which later integrate various data, open up more space for imagination.

So this LED lantern will not be popular? At least the team itself is very confident, they give two reasons:

First, LED lamps and smart phones are a large degree of popularity of hardware. According to the statistics at the beginning of this year, the total number of China's mobile Internet users reached 838 million; and large shopping malls are now LED needs a lot of lighting equipment, so the user can always come up with a mobile phone on the top of the lamp alignment positioning; at the same time, 2013-2015 will also be the rapid growth of LED lighting and stage rate.

Second, the use of this technology is very simple, very cheap. As long as each lamp lamp factory in LED to spend 10 dollars for a simple configuration, can realize the function of positioning, without changing the business trouble of equipment.
