Example Embodiment
[0043] Example one
[0044] Such as figure 1 As shown, Embodiment 1 of the present invention provides a short-range wireless information transmission method, which includes:
[0045] Step 101: The processor of the mobile terminal on the local side generates a digital signal according to the data to be sent, and sends it to the modem of the mobile terminal on the local side.
[0046] Among them, mobile terminals include smart phones, tablet computers, point of sale (POS) machines and on-board computers. A mobile terminal usually includes a processor, which is usually used for wireless communication services and application scenarios such as taking pictures, playing music and videos, and managing local files through a wireless network. In addition, the processor is also used for short-distance communication with other mobile terminals, such as face-to-face transmission or sharing of text, pictures, videos, etc.
[0047] The data to be sent is data that needs to be transmitted to anothe...
Example Embodiment
[0068] Example two
[0069] Such as figure 2 As shown, the second embodiment of the present invention provides a mobile terminal 20, and the mobile terminal 20 includes:
[0070] The processor 21 is configured to generate a digital signal according to the data to be sent and send it to the modem 22.
[0071] The modem 22 is used to generate a modulated signal according to the digital signal and send it to the laser 23.
[0072] The laser 23 is used to generate and emit a laser signal according to the modulation signal.
[0073] Among them, the laser signal generated by the laser 23 is directly emitted, without the convergence processing of the lens group of the optical transmitting antenna, so as to facilitate the aiming and connection establishment of the opposite mobile terminal.
[0074] The optical receiving antenna 24 is used to receive laser signals and send them to the photoelectric converter 25.
[0075] The photoelectric converter 25 is used to generate an electric signal accord...
