| 摘 要： | 设计一种基于单片机ATmegal6L控制的多脉冲序列发生器，以满足需要自动重复启动设备的需要。该多脉冲序列发生器通过接收外部TTL触发，可发出设定数量和周期的TTL脉冲序列。该系统已成功用于国家大科学装置EAST中，控制时间分辨率为5～100ms的光谱仪。通过该脉冲序列发生器输出的TTL脉冲序列电平能重复开启光谱仪，实现光谱仪的高速测量。

| Abstract: | A multi-pulse sequence generator based-on ATmegal6L MCU has been designed for automatic startup equipments. This equipment can send TTL pulse sequence with assigned quantity and period via external trigger signal. The period and quantity of pulse can be adjusted according to scenario. This system has been used in national large- equipment EAST for science research to control the spectrometer with 5 - lOOms time resolution. The TTL signal generated by multi-pulse sequence can startup spectrometer repeatedly only to achieve high-speed measurement. |
