摘要
为解决航空发动机转子部件在高速旋转工况下的非接触信号传输难题,设计了一种旋转环境下的无线激光通信系统。该系统采用垂直腔面发射激光器(VCSEL)与PIN光电二极管构建光通信链路,通过现场可编程门阵列(FPGA)主控模块协调MAX3656驱动芯片和MAX3760/MAX3762放大电路,实现电/光/电信号的高效转换与处理;结合自主开发的上位机软件,完成数据的实时解析与显示。实验结果表明:系统在20 cm传输距离下可实现100 Mb/s的稳定数据传输,功耗仅为3.45 W,且输入信号频率小于等于100 MHz时无波形失真,上位机数据解析零误码。
To address the challenge of non-contact signal transmission for high-speed rotating components in aero-engines,a wireless laser communication system for rotating environments was designed.The system employs a vertical-cavity surface-emitting laser(VCSEL)and a PIN photodiode to establish an optical communication link.A field-programmable gate array(FPGA)master control module coordinates the MAX3656 driver chip and MAX3760/MAX3762 amplifier circuits to achieve efficient electrical/optical/electrical signal conversion and processing.Combined with self-developed host computer software,real-time data parsing and display are accomplished.Experimental results demonstrate that the system achieves stable data transmission at 100 Mb/s over a 20 cm distance,with a power consumption of only 3.45 W.No waveform distortion occurs when the input signal frequency is≤100 MHz,and zero bit errors are observed in host computer data parsing.
