本文提出并实现了一套远程光纤供能的视频监控系统。这套系统包括远端单元、基站单元和上位机软件。远端单元以OV2640 CMOS为图像传感器、STM32为主控芯片采集数据，同时远端集成有光伏电池，将基站提供的光能经光电转换后给后级供电。基站单元采用输出激光束波长为810nm的高功率激光器提供能量，并将接收到的数据通过FT232RL接口转换芯片发送到PC端。基站和远端之间通过两根光纤连接，一根是传输波长为1310nm的单模光纤，用来传输视频数据，另一根是传输波长为810nm的多模光纤，用来传输能量。上位机软件选用可以进行实时图像信号接收的串口调试助手。

This paper proposes and implements a video surveillance system powered by distance fiber. This system includes the remote unit, the base station unit, and the upper computer software. The remote unit is mainly combined with an imaging sensor OV2640 CMOS and a control chip STM32. Also, it integrates photovoltaic cell to supply power to other circuits after photovoltaic conversion. The base station unit is used to supply power by a high-power laser in the base station unit transmitting a laser beam wavelength of 810 nm, and to send data to PC ports through interface convention chip FT232RL. The base station unit and the remote unit are connected with two fibers. One is a single mode fiber with 1310 nm transmission wavelength to transmit video data. Another one is a multimode fiber with 810 nm transmission wavelength to transmit energy. A serial debugging assistant is functioned as the upper computer software for real-time data accepting.
