Problems solved by technology
Communication terminals such as mobile phones will have a large power loss due to the use of radio wave antennas, and face the problem of irreconcilability between high power consumption and high-speed data transmission
The duration of high-rate burst data is too long, which will significantly shorten the standby time and use time of communication terminals such as mobile phones
However, the detection accuracy of the existing photoelectric sensors has been greatly improved, the power consumption of light emitting diodes (LEDs) is extremely low under the current technical conditions, and the device technology has been improved, which provides the possibility for information transmission by optical signals.

The invention discloses an interface adapter, a terminal, and a visible light communication system. The interface adapter comprises: a first processor, configured to process respectively signals transmitted from a network and on a power supply line, wherein the signal transmitted on the power supply line is obtained after processing of a visible light signal received by the terminal; a network interface module, connected to the first processor, configured to convert the signal on the network into a signal that the first processor is able to process, and configured to transmit the converted signal to the first processor, such that a visible light signal is obtained through conversion by the terminal and is sent by the terminal; a first front end module, connected to the first processor, configured to receive the signal on the power supply line and transmit the signal to the first processor for processing, and configured to send a signal, which needs to be sent for transmission by the first processor, onto the power supply line. Through the above mode, the visible light communication system is high in transmission rate, low in cost and high in anti-interference capability.
Description
technical field [0001] The invention relates to the field of portable electronic equipment, in particular to an interface adapter, a terminal and a visible light communication system. Background technique [0002] Traditional communication systems are all communication systems with electromagnetic waves as the medium. Electromagnetic wave communication has many weaknesses, such as radiation problems and interference problems. Communication terminals such as mobile phones will have a large power loss due to the use of radio wave antennas, and face the problem of irreconcilability between high power consumption and high-speed data transmission. If the duration of high-rate burst data is too long, the standby time and usage time of communication terminals such as mobile phones will be significantly shortened. However, the detection accuracy of existing photoelectric sensors has been greatly improved, and light emitting diodes (light emitting diodes, LEDs) have extremely low po...
