Abstract

The invention discloses a simultaneous interpretation device based on the visible light communication technology, and a working method of the simultaneous interpretation device. A transmitting moduleincludes four digital audio collecting units, a data integrating unit, an LDPC coding unit, a PPM modulation unit, a rate control unit, and an LED light emitting unit. A receiving module includes a light detecting unit, a signal extracting unit, a PPM demodulating unit, an LDPC decoding unit, an RAM storage unit, a language selection unit, and a digital audio output unit. The transmitting module and the receiving module are implemented through taking a ZYBO development board as a core platform. The device is advantageous in that the device is simple in system; the device can freely select languages and audios, is strong in anti-interference capability and is especially suitable for a safety secret occasion.

Description

technical field [0001] The invention relates to a simultaneous interpretation device, in particular to a simultaneous interpretation device based on visible light communication technology and a working method thereof. Background technique [0002] In recent years, with the global emphasis on clean energy and green environmental protection, high-brightness visible light LEDs have developed rapidly due to their significant advantages such as high energy efficiency and no pollution. LED is gradually replacing traditional incandescent and fluorescent lamps, becoming the next generation of new lighting sources. The high-speed electro-optic response of LEDs makes them also useful as communication light sources. Visible light communication relies on LEDs to send out high-speed bright and dark flickering signals that are completely imperceptible to the human eye to transmit information. Therefore, LED has dual functions of lighting and communication, which is of great significance...
