摘　　要：根据单光纤激光点火装置的功能需求,研制了单光纤激光点火样机的控制系统,该系统采用双波长单光纤的光路设计结构,与单光源双光纤结构相比具有更高的可靠性与安全性。系统主要包含人机通信模块、激光器驱动模块、光电转换模块、点火时间测量模块、安保模块等几个部分。以触摸屏作为人机交互的界面与主控制器之间进行相互通信,实现对各个功能模块的控制。利用MDK开发工具设计了系统软件,并进行了整机输出测试。结果表明:安保模块中光开关的插入损耗小于3 dB;当检测激光功率为1 mW、脉宽为20 ms时,检测电压大于1. 2 V,表明系统光路具有连续性;整机输出功率与设置功率的最大偏差不超过3%。According to the functional requirements of the single fiber laser ignition prototype,the control system of the single fiber laser ignition prototype i s developed,the system adopts a dual-wavelength single-fiber optical path design structure,which has higher reliability and safety than a single-source dual-fiber structure. The system mainly includes human-machine interaction interface,laser driving module,photoelectric conversion module,ignition time measurement module,security module and other parts. The touch screen is used as a human-computer interaction interface to communicate with the main controller to realize the control of each functional module. The system software is designed with MDK development tools,and the whole machine output test is carried out.
