Abstract

The invention discloses a method and a system for cooperative work of visible light positioning and bluetooth communication. The method comprises the steps of configuring and deploying an LED lamp capable of being modulated so as to enable the LED lamp capable of being modulated to give out visible light with a characteristic frequency band which is acquired by a camera of intelligent mobile equipment; carrying out imaging on the visible light acquired by the camera of the intelligent mobile equipment so as to extract light and shade ripples, and recognizing characteristics of the light and shade ripples so as to read a corresponding 32-bit coding ID; acquiring the current location of the intelligent mobile equipment according to a map of location where the coding ID and the LED lamp capable of being modulated are deployed inside a building; and acquiring a broadcast ID of a bluetooth module of the lamp capable of being modulated according to the 32-bit coding ID, and reading broadcast information according to the broadcast ID. According to the method disclosed by the invention, visible light positioning and bluetooth communication are utilized in a combined manner so as to carry out cooperative work, and thus problems of navigation, positioning and services indoor of a mobile intelligent application are solved, and the method is simple and reliable.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for cooperating work of visible light positioning and Bluetooth communication. Background technique [0002] With the popularity of mobile wireless communication devices, such as smart phones and tablet computers, the functions of mobile wireless communication devices are becoming more and more powerful. People have more and more requirements for the functions of accessing the network to send and receive short messages, emails and surfing the Internet anytime and anywhere. In order to provide better services for people, a large number of mobile applications (APP) have emerged. One type of mobile application needs to work according to the current location of the mobile wireless communication device. This type of mobile application is called location-based service (Location Based Service), such as shopping guide service in the mall and accurate advertisin...
