摘　　要：为高效精准地采集激光脉冲信号,设计了一种基于嵌入式技术的激光脉冲信号采集系统。构建激光脉冲信号采集系统,由信号采集模块采集初始激光脉冲信号,并传送至信号调理模块进行调理,再将调理后的信号数据存入缓存模块;然后由嵌入式处理模块的核心ARM读取缓存模块内信号数据,对信号数据进行处理后,通过界面显示模块呈现给用户。结果表明,该系统可有效去除噪声,激光脉冲信号采集精度在90%以上,并且能够在不到1.3 s的时间内实现信号提取。In order to collect laser pulse signals efficiently and accurately, a laser pulse signal acquisition system based on embedded technology is designed. The laser pulse signal acquisition system is constructed. The initial laser pulse signal is collected by the signal acquisition module and transmitted to the signal conditioning module, and then the conditioned signal data is stored in the buffer module. Then, the core arm of the embedded processing module reads the signal data in the cache module, processes the signal data, and presents it to the user through the interface display module. The results show that the system can effectively remove noise, the laser pulse signal acquisition accuracy is more than 90%, and the signal extraction can be realized in less than 1.3 s.
