摘　　要：为了稳定可靠地触发CO2激光器旋转火花开关,设计了高压脉冲触发系统的信号源。该系统采用多脉冲触发模式,其信号源采用PIC单片机为主控芯片,采用复杂可编程逻辑器件CPLD为时序发生器。单片机用于脉冲类型的选择与控制,CPLD用于生成1Hz、100Hz、200Hz、300Hz、400Hz、500Hz的重频脉冲触发信号以及单次脉冲触发信号。操作者可通过按键实现两种不同占空比脉冲切换,通过拨码开关实现不同频率脉冲信号的输出选择。实验结果表明,该信号源输出脉冲信号稳定、可靠,满足设计要求。In order to improve the reliability of triggering rotated spark switch, a high-voltage pulse trigger system＇s pulse signal source is developed. The system works in multipulse trigger mode. The signal source adopts PIC MCU as the main control chip, and uses a complex programmable logic device CPLD as timing generator. Single chip microcomputer is used in pulse type selection and control. CPLD is used to generate repetition trigger pulse signals and single trigger pulse signals. The running frequencies are 1Hz、100Hz、200Hz、300Hz、400Hz and 500 Hz. The operator can through the button to achieve two different pulse duty cycle switches and can through dial switch to achieve different frequency pulse signal output options. The experimental results show that, the signal source output pulse signal is stable, reliable, and meet the design requirements.
