摘要: 在激光等离子体机理的研究中，为实现灵活的界面配置和多路脉冲激光器高精度的时序延时，设计了一种基于微控制器STM32和FPGA的多路时序延时控制系统。重点介绍了基于FPGA的多路ns级时序信号和基于ucGUI的触摸屏界面的设计。另外，采用高速光电隔离技术和高速FET开关电路技术，对驱动电路进行了设计，缩短了输出脉冲上升沿的时间，提高了系统延时精度、驱动能力和抗干扰性能。测试结果表明，该设计每路延时可调，调节范围为5 ns~10 ms，最小可调步进为5 ns，延时误差小于1 ns。Abstract: In order to realize flexible interface setting and high-precision timing control between multi-channel pulse lasers, a multi-channel timing control system was designed based on STM32 and FPGA. This paper mainly introduces the generation of multi-channel nanosecond timing signal based on FPGA and the design of touch panel interface based on ucGUI. The driver circuit was designed using high-speed optical isolation technology and high-speed switch circuit technology, which shortened the rise time of pulse outputs, improved delay precision, driver capability and anti-interference performance. The design ensures that each channel delay can be set with in the range from 5 ns to 10 ms , with minimum step of 5 ns, and precision of the system delay time is less than 1 ns.
