Problems solved by technology

[0003] The above-mentioned transmission methods have the following problems: the amount of data transmitted by wireless Bluetooth technology is too small, and the transmission rate is not high, especially in scenarios where wireless technology cannot be used (such as in the cabin during flight, in high-risk mines, etc.), it is difficult to play effect
There is a certain transmission delay in the transmission via the third-party network, and the transmission efficiency is low and the speed is slow for large-capacity files
Especially when the third-party network fails and suspends the service, the data transmission between mobile terminals will not be possible

Embodiment 1

[0035] In order to further describe the present invention in detail, on the basis of the above technical solutions, the following payment examples between mobile phones and mobile terminals are given, so that the payment method can be realized through short-distance point-to-point visible light duplex communication, so that it can be used at different times In the case of networking, the confirmation of the receiving and paying parties is realized. At the same time, the point-to-point communication is more secure and reliable, the connection is stronger, the communication is not easy to be stolen, and the face-to-face transfer is easier to determine the identity information. At the same time, the communication speed is faster and there is no additional cost. .

[0036] The following embodiments use the built-in flashlight, camera or external device of the mobile phone as the visible light communication transmitting and receiving module.

Abstract

The invention provides a communication terminal visible light t data transmission device and a transmission method. The device realizes the data transmission by using the light source and a camera of the mobile terminal. A light source built-in electro-optic converter of the communication terminal converts an electric signal into an optical signal, and the data information is externally sent by using a light source way; an optical-electric detector and an optical-electric converter are built in the camera of the communication terminal, thereby converting the optical signal of the light source into the electric signal and finishing the receiving function of the data information. The device provided by the invention can realize the data sending and receiving between the communication terminals with the light source and the camera function without depending on the third-party network and without needing the additional data connection line.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a data transmission device and a data transmission method of a mobile terminal light source for visible light communication. Background technique [0002] With the vigorous development of mobile Internet services, data transmission between mobile terminals is becoming more and more frequent, and the amount of data is also increasing rapidly. At present, apart from a small amount of data between mobile phone terminals being transmitted via wireless Bluetooth technology, most of the data volume still needs to be transferred by means of a third-party network for transmission. [0003] The above-mentioned transmission methods have the following problems: the amount of data transmitted by wireless Bluetooth technology is too small, and the transmission rate is not high, especially in scenarios where wireless technology cannot be used (such as in the cabin during flig...
