基于LED可见光通信的中英同声传译系统

The Chinese-English Simultaneous Interpretation System Based on LED Visible Light Communication

针对会议中采用的同声传译系统存在设备铺设麻烦,信号受到干扰重叠或用户数量有限等问题,根据会议同声传译系统在室内使用的特点,提出利用照明LED光源进行可见光通信来实现信号的传输。综合利用,STC单片机、LED驱动电路,LED灯、光电传感器,蓝牙模块和树莓派等硬件模块,通过科大讯飞开放平台进行语音识别、转写、机器翻译,实现了中英同声传译功能。通过实验对系统可靠性进行了验证,系统能够准确进行语音翻译,并通过LED灯将信息发送至接收端,完成同声传译功能。

The simultaneous interpretation system used in the conference has troubles in laying equipment,overlapping signals,or limiting the number of users.Considering the system is used indoors,this paper proposes that the illuminated LED light sources can be used for visible light communication to achieve signal transmission.The system is composed of STC microcontroller,LED drive circuit,LED light,photoelectric sensor,Bluetooth module,Raspberry Pi and other hardware modules.And through the language platform provided by iFLY TEK,the system can recognize,transliterate and translate the received speech to achieve the simultaneous interpretation function.It has been proved in experiments that the system is reliable,and it can accurately translate the speech and send it to the receiving end through LED lights to realize the simultaneous interpretation function.
