摘　　要：以LED为核心的可见光通信是通信领域极具发展潜力的重要方式。针对LED光通信系统的要求,采用基于AVR的嵌入式结构及虚拟仪器技术,设计了具有较小体积和较低成本的发射接收控制系统。系统采用虚拟仪器平台作为通信系统的发射源和接收端子,并采用电荷泵升压器件AAT3110驱动LED,结合低偏移电压精密放大器OPA2350实现PC利用LED可见光通信。实验结果表明,系统稳定可靠,能够较好满足设计要求。The LED visible light communication （VLC） is the extremely important ways with development potential in communications. According to the requirements of LED communication, Virtual Instruments and LED VLC control system based on ARM embedded structure is designed with smaller size and lower cost. The system uses Virtual instrument platform as the source communication system transmitting and receiving terminals, while AAT3110 charge pump step-up device drivering LED, combined with low offset voltage precision amplifier OPA2350 to achieve PC communication with LED. The experimental results indicate that the system is stable, which can satisfy the design requirements.
